Overview PART I We are a clinical-stage biopharmaceutical company focused on the development and commercialization of novel therapies for cardiopulmonary diseases. Our lead product candidate, PB2452, is a novel reversal agent for the antiplatelet drug ticagrelor, which we are developing for the reversal of the antiplatelet effects of ticagrelor in patients with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure. Based on feedback from the United States Food and Drug Administration, or FDA, we intend to seek approval of PB2452 in the United States through an accelerated approval process. In September 2019, we completed a Phase 2a clinical trial of PB2452 where we observed immediate and complete reversal of ticagrelor’s antiplatelet activity within five minutes following initiation of infusion and sustained reversal for over 20 hours. PB2452 has been generally well tolerated in our completed trials, with no drug-related serious adverse events, or SAEs. We are currently conducting a Phase 2b trial of PB2452 and recently commenced our pivotal Phase 3 clinical trial. We are developing PB2452 pursuant to a co-development agreement, or the SFJ Agreement, with SFJ Pharmaceuticals X, Ltd., an SFJ Pharmaceuticals Group company, or SFJ. Under the SFJ Agreement, SFJ has agreed to pay us up to $120.0 million to support the clinical development of PB2452. Our second product candidate, PB1046, is a once-weekly fusion protein currently in a Phase 2b clinical trial for the treatment of pulmonary arterial hypertension, or PAH. PB1046 utilizes our proprietary half-life extending elastin-like polypeptide, or ELP, technology, which also serves as an engine for our preclinical pipeline. As we advance our clinical programs for PB2452 and PB1046 with site activations and patient enrollment, we remain in close contact with our clinical research organizations, clinical sites and suppliers to attempt to assess the impacts that COVID-19 may have on our clinical trials and current timelines and to consider whether we can implement appropriate mitigating measures to help lessen such impacts. At this time, however, we cannot fully forecast the scope of impacts that COVID-19 may have on our ability to initiate trial sites, enroll and assess patients, supply study drug and report trial results. We are also developing our preclinical product candidate, PB6440, for treatment- resistant hypertension. We retain worldwide commercial rights to all of our product candidates. PB2452 PB2452 is a novel recombinant human monoclonal antibody antigen-binding fragment, or Fab fragment, designed to reverse the antiplatelet activity of ticagrelor. Ticagrelor is an antiplatelet therapy widely prescribed to reduce the rates of death, heart attack and stroke in patients with acute coronary syndrome, or ACS, or who have previously experienced a heart attack. The American College of Cardiology, American Heart Association and European Society of Cardiology guidelines recognize ticagrelor as the preferred antiplatelet therapy for ACS. In 2019, ticagrelor, currently marketed by AstraZeneca plc, or AstraZeneca, under the brand names Brilinta and Brilique, had worldwide sales of $1.6 billion, an increase of 20% over 2018 sales. Ticagrelor binds to platelets to prevent them from forming blood clots, which could restrict blood flow to critical organs in these patients, causing heart attacks or strokes. Due to ticagrelor’s antiplatelet activity, patients on ticagrelor have an elevated risk of spontaneous bleeding. In addition, patients on ticagrelor who need urgent surgery cannot wait the recommended five days for ticagrelor’s effect to dissipate and are at increased risk of major bleeding during and after surgery. There are currently no other known reversal agents approved or in clinical development for ticagrelor or any other antiplatelet drugs. In the European Union, an extracorporeal whole blood purification adsorber device is available that may be useful for non-specific removal of ticagrelor during some cardiac procedures when used in conjunction with cardiopulmonary bypass. Upon approval, PB2452 would be the only therapeutic agent available for specific reversal of ticagrelor. We believe the availability of PB2452 as a specific reversal agent could expand ticagrelor's use by mitigating concerns regarding bleeding risk and uniquely position ticagrelor as the only oral antiplatelet drug with a reversal agent. In our Phase 1 and Phase 2a clinical trials, PB2452 achieved immediate and complete reversal of ticagrelor’s antiplatelet activity, with potential customizable duration of reversal based on the dosing regimen, which we believe has the potential to bring life-saving therapeutic benefit to these patients by increasing the safety of ticagrelor. In September 2019, we completed a Phase 2a clinical trial of PB2452 in older and elderly subjects dosed with ticagrelor and aspirin and in healthy younger subjects on supratherapeutic doses of ticagrelor. In this trial, we observed a statistically significant reversal of ticagrelor within five minutes of initiation of PB2452 infusion, which was sustained for over 20 hours. Platelet function was normalized by 15 minutes, 30 minutes for the supratherapeutic ticagrelor-dose cohort, following initiation of PB2452 infusion and remained normal for over 20 hours. PB2452 was generally well tolerated, with only minor adverse events, or AEs reported. These results are consistent with results observed in healthy younger subjects treated with ticagrelor in our Phase 1 trial. The older and elderly subjects in the Phase 2a trial resembled the patient population most likely to be treated with ticagrelor and to potentially benefit from PB2452, if approved. 3 The FDA granted Breakthrough Therapy designation for PB2452 in April 2019. The European Medicines Agency, or the EMA, granted PB2452 Priority Medicines, or PRIME, designation in February 2020. Based on feedback from the FDA, we intend to submit a Biologics License Application, or BLA, for potential accelerated approval based on an interim analysis of the first approximately 100 patients treated in our Phase 3 trial, with approximately 50 patients with uncontrolled major or life-threatening bleeding and approximately 50 patients requiring urgent surgery or an invasive procedure. We recently commenced our pivotal Phase 3 clinical trial. Based on an 18-month estimated enrollment timeline for the first 100 patients in the Phase 3 trial, we are targeting to submit our BLA for PB2452 in the second half of 2022. To support full approval for patients with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure, and consistent with the recommendation of the FDA, we plan to enroll a total of 200 patients in the Phase 3 trial. After we submit our BLA with data from the first 100 patients, we intend to complete the Phase 3 trial and establish a post-approval registry in accordance with FDA requirements. The Committee for Medicinal Products for Human Use, or CHMP, of the EMA has also generally agreed with our proposed clinical development plan for PB2452. PB1046 PB1046 is being developed as a once-weekly, novel treatment for PAH, a progressive, life-threatening, orphan disease caused by vasoconstriction and structural deterioration of the pulmonary arteries, which can lead to heart failure and, eventually, death. PB1046 is a subcutaneously- injected, sustained-release analogue of the native human peptide vasoactive intestinal peptide, or VIP. VIP is a neurohormone that relaxes the muscles surrounding blood vessels, causing them to dilate, which results in improved blood flow. In contrast to the currently approved therapies for PAH, which only target vasodilation, we believe that VIP also suppresses the adverse remodeling of blood vessels and increases cardiac contractility and relaxation. We believe that PB1046 has the potential to be disease-modifying and complementary to current standard-of-care therapies for PAH. We have completed two clinical trials of subcutaneously-injected PB1046 in subjects with cardiovascular diseases. In these trials, PB1046 was observed to be well tolerated, with no drug-related SAEs. In both trials, we observed that patients who received PB1046 experienced statistically significant reductions in blood pressure that were sustained for at least one week, with no reported episodes of symptomatic hypotension. We have also completed enrollment of an exploratory Phase 1b/2a clinical trial to evaluate the effects of PB1046 on pulmonary arterial pressure in PAH patients with a CardioMEMS device, an implanted hemodynamic monitor that continuously reports pulmonary arterial pressure and cardiac function. In preliminary results from this trial, we observed reductions in pulmonary arterial pressure and increases in cardiac output, which we believe are consistent with potential beneficial effects of PB1046. We have begun dosing patients in a randomized, double-blinded, controlled Phase 2b clinical trial in which we plan to enroll approximately 60 PAH patients to assess the safety, tolerability and efficacy of PB1046. This clinical trial will evaluate the effects of PB1046 on pulmonary arterial pressure and exercise tolerance, including the distance the patient can walk in six minutes, which is an important clinical endpoint that the FDA has previously used as the basis for approval of other PAH drugs. We have temporarily paused enrollment of new patients in this trial as a precaution to minimize potential exposure of this patient population at high risk of serious illness from COVID-19. However, we have also informed investigators that they may continue dosing PB1046 and performing assessments for current trial participants if they deem it appropriate and such activities are permitted by their respective institutions. Additionally, we continue to identify new trial sites for future initiation. Although we have been targeting to report results from this trial in the fourth quarter of 2020, we believe that the COVID-19 outbreak will temporarily prevent us from being able to initiate new trial sites and enroll new patients, likely delaying our ability to report the results of this trial into 2021. PB1046 and certain other preclinical product candidates, are based on our proprietary ELP technology. Our ELP technology extends the circulating half-life of proteins and peptides and also provides a sustained-release mechanism, resulting in exposure of active molecules for periods of a week or longer from a single subcutaneous injection. We believe that our ELP technology enhances solubility, stability and bioavailability, provides extended drug exposure and creates product candidates that are straightforward to manufacture and administer. Our strategy is to apply our ELP technology to proteins and peptides with well-characterized therapeutic activities but suboptimal half-lives to improve their pharmacokinetics, enable their use as pharmaceutical products and allow for more convenient dosing regimens. To date, we have not observed any drug-related SAEs in any of the over 500 subjects in clinical trials of our ELP product candidates. PB6440 PB6440 is a highly selective aldosterone synthase inhibitor being developed for treatment-resistant hypertension. In preclinical studies to date, PB6440 demonstrated dose-dependent aldosterone reduction without a significant increase in 11-deoxycorticosterone or deoxycortisol in both rodent and primate models. The oral bioavailability and pharmacokinetic profiles observed in these preclinical studies appear suitable for once-daily oral dosing in humans. To date, no evidence of toxicity has been observed in either in vitro toxicity studies or in animal models, including primates. We currently plan to initiate 4 nonclinical Investigational New Drug Application, or IND, -enabling studies for PB6440 in 2020, which are expected to be followed by an IND filing and a first-in-human trial in early 2021. Strategy include: Our strategy is to identify, develop and commercialize novel therapies for cardiopulmonary diseases. The key elements of our strategy • • • • • • Continue to advance PB2452 through clinical development and regulatory approval. We intend to develop and commercialize PB2452 as a novel reversal agent for the antiplatelet drug ticagrelor. We recently completed a Phase 2a clinical trial of PB2452 in older and elderly subjects dosed with ticagrelor and aspirin and in healthy younger subjects on supratherapeutic doses of ticagrelor. In October 2019, we initiated a multi-center Phase 2b clinical trial in healthy older and elderly subjects. In collaboration with SFJ, we recently commenced our pivotal Phase 3 clinical trial in patients on ticagrelor with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure, and we plan to perform an interim assessment of an initial subset of patients in this trial. We have received Breakthrough Therapy designation and plan to submit a BLA seeking accelerated approval of PB2452 prior to completion of the Phase 3 clinical trial, based on biomarker data from an initial subset of the Phase 3 patients. The EMA granted PB2452 PRIME designation, and the CHMP has generally agreed with our clinical development plan. Continue to develop PB1046. We intend to advance PB1046 through clinical trials as a once-weekly novel treatment for PAH that is vasodilatory, potentially disease-modifying and complementary to the current standard of care therapies. We are currently conducting a Phase 2b clinical trial of PB1046. We have temporarily paused enrollment of new patients as we assess the impact of COVID-19. Based on the results of this trial, we intend to advance this product candidate into Phase 3 clinical development for the treatment of PAH. Broaden the potential therapeutic applications of PB1046. Due to improvements in pharmacokinetics that we have observed with our ELP technology, we believe that the therapeutic potential of VIP can be applied to a variety of other orphan indications. Preclinical data suggest PB1046 may have clinical benefit in cardiomyopathy associated with Duchenne Muscular Dystrophy, or DMD, heart failure and other cardiomyopathies and in cystic fibrosis. As such, we intend to strategically broaden the therapeutic applications of PB1046 by exploring its development in additional indications. Continue the preclinical development of PB6440 for treatment-resistant hypertension. We are planning to initiate IND-enabling studies for PB6440 in 2020. We expect to file an IND for PB6440 with the FDA in order to initiate a first-in-human trial in early 2021. Leverage our ELP technology platform to expand our development pipeline. We believe that our ELP technology enhances solubility, stability and bioavailability, provides extended drug exposure and creates product candidates that are straightforward to manufacture and administer. As such, we plan to utilize our platform to identify product candidates for additional indications. We intend to apply our ELP technology to improve the pharmacokinetics of proteins and peptides with well-characterized therapeutic activities but suboptimal half-lives, in order to improve their pharmacokinetics, enable their use as pharmaceutical products and allow for more convenient dosing regimens. Commercialize our product candidates. We have entered into exclusive license agreements with AstraZeneca for PB2452 and Duke University, or Duke, for our ELP technology pursuant to which we retain worldwide commercial rights to our product candidates. In addition, we own all of the assets and intellectual property rights related to PB6440. If approved, we intend to commercialize PB2452 and PB6440 independently in the United States and with a collaboration partner internationally. We intend to explore collaborations or partnerships to commercialize PB1046, if approved. As we advance towards regulatory approvals for our product candidates, we intend to establish a focused marketing and sales infrastructure. Pipeline Our preclinical and clinical-stage pipeline is set forth below: 5 PB2452: Antiplatelet Therapy Reversal Agent for Ticagrelor Our lead product candidate, PB2452, is a novel ticagrelor reversal agent, which we are developing for the reversal of the antiplatelet effects of ticagrelor in patients with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure. In September 2019, we completed a Phase 2a clinical trial of PB2452 in older and elderly subjects and in healthy younger subjects on supratherapeutic doses of ticagrelor, in which we observed a statistically significant reversal of ticagrelor within five minutes of initiation of PB2452 infusion, which was sustained for over 20 hours. We are currently conducting a Phase 2b clinical trial of PB2452 and recently commenced our pivotal Phase 3 clinical trial. Background on Acute Coronary Syndrome ACS describes a range of conditions associated with sudden reduced blood flow to the heart, including unstable angina and myocardial infarction, or heart attack. ACS is caused by the inappropriate formation of clots in the coronary arteries. These blood clots are made up primarily of platelets, small lens-shaped cells found in the blood that normally aggregate at sites of injury to help stop bleeding. According to the Centers for Disease Control and Prevention, approximately 805,000 Americans have a heart attack every year, and heart attacks are a leading cause of death in the developed world. The primary treatment for ACS is the use of antiplatelet drugs to prevent the worsening of existing clots or to reduce the formation of additional clots. These clots can occur in the heart or in stents that are placed in the blocked coronary artery to keep the blood vessel open or elsewhere in the body. Without antiplatelet drugs, patients are at a significantly increased risk of recurrent heart attacks, stroke and death. The standard of care for ACS patients is dual antiplatelet therapy, or DAPT, which is a combination of aspirin and an inhibitor of a specific receptor found on platelets known as the P2Y12 receptor. This combination is started after a patient experiences a heart attack or other manifestation of ACS and has been shown to significantly reduce platelet aggregation and clot formation and reduce the frequency of recurrent heart attacks, stroke and death. While the antiplatelet drugs used in DAPT have proven effective at improving overall outcomes in ACS patients, their suppression of blood clotting increases patients’ risk of bleeding. Bleeding events in patients on antiplatelet therapy, which can occur spontaneously or as a result of injury or surgery, are classified as minor or major. In the 18,000-patient clinical trial, Platelet Inhibition and Patient Outcomes, or PLATO, conducted by AstraZeneca, ticagrelor was shown to be superior to the antiplatelet drug clopidogrel, marketed under the brand name Plavix, in reducing recurrent heart attack, stroke and death in patients with ACS. However, in both treatment groups, 11% to 12% of patients in the trial suffered major bleeding events, and in 5.8% of patients, these major bleeding events were fatal or life-threatening. The causes of bleeding varied in the trial population. In approximately 3% of the patients on ticagrelor, the major bleeding events were spontaneous and not related to any medical procedure, whereas approximately 9% of patients on ticagrelor developed major bleeding that was related to procedures like coronary artery bypass surgery, or CABG. Although the trial protocol recommended that patients who needed CABG stop taking ticagrelor for one to three days prior to surgery, nearly half of all ticagrelor patients needed surgery urgently and could not wait the up to three days for ticagrelor’s effect to dissipate so normal blood clotting could be restored. Overall, up to 80% of patients who underwent CABG surgery in the trial suffered a major or life-threatening bleeding event related to the surgery, and for those who needed urgent surgery and could not wait three days for the effects of ticagrelor to dissipate, 6 approximately 50% experienced a fatal or life-threatening bleeding event. While some of this risk was likely associated with patients’ underlying conditions, the overall bleeding risk is significantly increased by antiplatelet drugs, and the current United States and European prescribing information for ticagrelor suggests suspension of ticagrelor treatment for five days prior to surgery. Despite the increased bleeding risk, antiplatelet drugs, along with anticoagulant drugs that are used to prevent clots in veins, represent some of the most widely prescribed drugs in the United States due to their lifesaving effects. There are currently no other known reversal agents approved or in clinical development for ticagrelor or any other antiplatelet drugs. In the European Union, an extracorporeal whole blood purification adsorber device is available that may be useful for non-specific removal of ticagrelor during some cardiac procedures when used in conjunction with cardiopulmonary bypass. Upon approval, PB2452 would be the only therapeutic agent available for specific reversal of ticagrelor. In the absence of a specific reversal agent, physicians have limited treatment options, and sometimes administer platelet transfusions, which are unproven in this setting. The ability to quickly reverse the antiplatelet activity of ticagrelor and restore normal clotting would increase its safety, both in instances of major bleeding as well as in situations where surgical or other medical interventions associated with bleeding are urgently needed. Background on Antiplatelet Drugs The three oral antiplatelet P2Y12 receptor antagonist drugs prescribed in DAPT are clopidogrel, marketed under the brand name Plavix; prasugrel, marketed under the brand name Effient; and ticagrelor, marketed under the brand names Brilinta and Brilique. Unlike clopidogrel and prasugrel that permanently bind to and inhibit the target receptors on platelets, ticagrelor binds to the P2Y12 receptor in a transient manner, quickly cycling on and off the receptor. We believe this transient binding of ticagrelor presents a unique opportunity to develop a specific reversal agent for ticagrelor, whereas the permanent binding of the other drugs to the receptor precludes a reversal agent from being developed. We consider ticagrelor to be the best-in-class P2Y12 antiplatelet agent because it has demonstrated a superior benefit-risk profile compared to other products in the P2Y12 class. In 2019, ticagrelor had worldwide sales of $1.6 billion, an increase of 20% over 2018 sales. Ticagrelor has achieved this level of market share despite the availability of generic versions of clopidogrel and prasugrel. We believe ticagrelor growth is being driven in part by treatment guidelines from the American College of Cardiology, American Heart Association and the European Society of Cardiology that recognize ticagrelor as the preferred antiplatelet treatment for ACS. We believe that the availability of a reversal agent could further drive the use of ticagrelor by making it the only reversible oral P2Y12 antiplatelet treatment, thereby conferring a possible safety benefit over the other agents. Furthermore, based on the growth of clopidogrel prescriptions after the introduction of a generic form of that drug, we believe ticagrelor prescriptions could grow significantly after its patents expire in 2024 and generic competition drives prices down to similar levels as other P2Y12 antiplatelet therapies. Our Solution: PB2452 PB2452 is a human Fab fragment that binds to ticagrelor with high affinity and specificity to reverse ticagrelor’s antiplatelet activity. We believe that the availability of PB2452 may further differentiate ticagrelor from other P2Y12 receptor antagonists by providing for better clinical management of the balance between the desired antiplatelet effect and prevention or control of bleeding. We exclusively licensed PB2452 from MedImmune Limited, or MedImmune, a wholly-owned subsidiary of AstraZeneca. PB2452 Background Ticagrelor works by binding to the P2Y12 receptor on platelets, thereby preventing adenosine diphosphate, or ADP, from causing platelet aggregation. Ticagrelor binds transiently to the P2Y12 receptor, quickly cycling on and off, and allowing PB2452 to bind to free ticagrelor, thereby preventing ticagrelor’s inactivation of the receptor and removing ticagrelor from circulation. With ticagrelor removed, ADP can once again activate the P2Y12 receptor and induce platelet aggregation. This activity is illustrated below. Mechanism of action of ticagrelor and its reversal by PB2452 7 PB2452 binds to ticagrelor with an affinity that is approximately 100 times stronger than ticagrelor’s affinity for the P2Y12 receptor. This high affinity enables PB2452 to bind to free ticagrelor, resulting in an immediate reversal of ticagrelor’s effect and restoration of platelet activity. Clinical Development of PB2452 Phase 3 Clinical Trial We recently commenced our pivotal Phase 3 clinical trial. We expect to enroll a total of 200 ticagrelor patients with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure in this global, multi-center, non-randomized, open-label trial and file for an accelerated approval based upon approximately 100 patients. The primary endpoints for this trial are the reversal of the antiplatelet effects of ticagrelor with intravenous infusion of PB2452 as measured by the VerifyNow® PRUTest® biomarker and achievement of clinical hemostasis in enrolled patients. Phase 2b Clinical Trial In October 2019, we announced that the first patient had been dosed in the Phase 2b trial of PB2452. The multi-center, randomized, double-blind, placebo-controlled trial is designed to evaluate the safety and efficacy of PB2452 in reversing the antiplatelet effects of ticagrelor as part of a dual antiplatelet regimen including low-dose aspirin. Approximately 200 older and elderly (ages 50-80) subjects are expected to be enrolled, resembling the patient population most likely to be treated with ticagrelor and potentially benefit from PB2452, if approved. Subjects will be randomized in a ratio of 3:1 and will receive either PB2452 or placebo, with approximately 150 subjects receiving PB2452. The primary endpoint of the trial is reversal of the antiplatelet effects of ticagrelor with intravenous infusion of PB2452 or placebo, as measured by the VerifyNow PRUTest biomarker. We expect that the results of this trial will further support our BLA safety database. Phase 2a Clinical Trial 8 In September 2019, we completed a Phase 2a clinical trial of PB2452 in older and elderly subjects dosed with ticagrelor and aspirin and in healthy younger subjects on supratherapeutic doses of ticagrelor. We observed a statistically significant reversal of ticagrelor within five minutes of initiation of PB2452 infusion, which was sustained for over 20 hours. Platelet function was normalized by 15 minutes (30 minutes for the supratherapeutic ticagrelor-dose cohort) following initiation of PB2452 infusion and remained normal for over 20 hours. PB2452 was generally well tolerated, with only minor AEs reported. These results are consistent with results observed in healthy younger subjects treated with ticagrelor in our Phase 1 trial. The older and elderly subjects in the Phase 2a trial resemble the patient population most likely to be treated with ticagrelor and to potentially benefit from PB2452, if approved. Phase 1 Clinical Trial In September 2018, we completed a Phase 1 dose escalation clinical trial of PB2452, delivered as an intravenous infusion in healthy subjects pre-dosed with ticagrelor that was designed to identify the target dose, determine proof of concept and evaluate the safety and tolerability of PB2452. In the trial, we observed that PB2452 immediately and completely reversed the antiplatelet effects of ticagrelor. We conducted this trial pursuant to an IND application that we sponsored and that became effective in March 2018. In March 2019, the full results from this trial of PB2452 were published in the New England Journal of Medicine. Our Phase 1 clinical trial enrolled 64 subjects across 10 sequential dose cohorts. Based on pharmacokinetic and pharmacodynamic data from the early dose cohorts in the trial, we adjusted the intravenous infusion of PB2452 to identify the optimal dose and dosing regimen for future trials and for the target patient populations. The initial three cohorts of subjects were dosed with 30-minute intravenous infusions of PB2452 alone in order to assess pharmacokinetics and safety. Subsequent cohorts were pre-dosed with the standard clinical regimen of ticagrelor for two days prior to administration of PB2452 to enable direct assessment of reversal of ticagrelor’s inhibition of platelet aggregation using platelet function assays. There were no PB2452- related AEs or SAEs in any of the dose cohorts. In cohorts 5 and 6, which were the first cohorts in which potentially pharmacodynamically active doses of PB2452 were administered, we saw immediate and complete reversal of ticagrelor’s antiplatelet activity based upon restoration of platelet function. In 11 out of 12 subjects, platelet function was restored at the first measured time point at the end of the 30-minute infusion. The duration of reversal varied from approximately one to four hours depending upon the dose level and subject, with longer duration at higher doses. In cohort 7, we modified the dosing regimen to deliver a total dose of 18 g, with 3 g delivered in the first five minutes of infusion, followed by 15 g delivered at a constant rate over an additional seven hours and 55 minutes. In cohort 7, we observed that all subjects achieved complete and sustained restoration of platelet function within two hours after the start of infusion. The duration of reversal in cohort 7 lasted approximately 16 hours from the start of the infusion as measured by restoration of platelet activity. In cohorts 8, 9 and 10, the dosing regimen of PB2452 was further refined to achieve both a more rapid onset of reversal and a longer duration of reversal compared to earlier cohorts. We administered a total dose of 18 g, with the initial 6 g delivered as a bolus in cohorts 8, 9 and 10. The remaining 12 g was administered after the initial bolus for an additional 12 to 16 hours in cohorts 8, 9 and 10. In each of these cohorts, we observed both immediate and complete reversal within the first five minutes following initiation of infusion and a sustained duration of reversal of over 20 hours. We intend to further evaluate the dose and dosing regimens observed in these cohorts in future clinical trials. Future Clinical Development Plans Based on feedback from the FDA, we intend to submit a BLA for potential accelerated approval based on an interim analysis of the first approximately 100 patients treated in our Phase 3 trial, with approximately 50 patients with uncontrolled major or life-threatening bleeding and approximately 50 patients requiring urgent surgery or an invasive procedure. Based on an 18-month estimated enrollment timeline for the first 100 patients in the Phase 3 trial, we are targeting to submit our BLA for PB2452 in the second half of 2022. To support full approval for patients with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure, and consistent with the recommendation of the FDA, we plan to enroll 200 total patients in the Phase 3 trial. After we submit our BLA with data from the first 100 patients, we intend to complete the Phase 3 trial and establish a post-approval registry in accordance with FDA requirements. In April 2019, the FDA granted Breakthrough Therapy designation for PB2452. The EMA granted PB2452 PRIME designation, and the CHMP has generally agreed with our clinical development plan. PB1046 for the Treatment of Pulmonary Arterial Hypertension 9 We are developing our second product candidate, PB1046, as a once-weekly novel treatment for PAH. PB1046 is based on our proprietary ELP half-life extension technology. We are currently conducting a Phase 2b clinical trial in PAH patients to assess the safety, tolerability and efficacy of PB1046. We have received two orphan drug designations for PB1046 from the FDA: one for the treatment of PAH and a second for cardiomyopathy associated with DMD. In February 2018, we received Small Business Innovation Research, or SBIR, grants from the National Institutes of Health in an aggregate amount of $2.8 million to support the clinical development of PB1046 for the treatment of PAH for the period from February 17, 2018 to July 31, 2020. In connection with the SBIR grants, the United States government will receive a non-exclusive, royalty-free license to use any technology we develop under such grants. For the years ended December 31, 2019 and 2018, we had recognized $1.8 million and $0.7 million, respectively, of grant revenue under the SBIR grants. Background on PAH PAH is a progressive and life-threatening orphan disease with no known cure. Common symptoms, which worsen as the disease progresses, include shortness of breath, fatigue, angina, fainting, light headedness and abdominal distension. The disease is caused by abnormal constriction and adverse remodeling of the arteries and is characterized by high blood pressure in the pulmonary arteries, the blood vessels leading from the heart to the lungs. This pressure restricts blood circulation through the lungs resulting in poor oxygenation, abnormal strain on the heart’s right ventricle and underfilling of the left ventricle. Over time, the remodeling worsens as inflammatory cells are recruited. This leads to tissue scarring and fibrosis, which results in severe restriction of blood flow, increasing the risk of developing life-threatening blood clots, heart failure and premature death. The clinical severity of PAH is classified according to a system originally developed for heart failure by the New York Heart Association and then modified by the World Health Organization for patients with PAH, ranging from functional class I (no symptoms) through functional class IV (severe symptoms). Most standard-of-care therapy is initiated in patients who have progressed to class II or beyond. According to the Pulmonary Hypertension Association, there are approximately 30,000 patients diagnosed with PAH in the United States. There are several approved therapies for PAH, and patients initially start treatment with a combination of two oral therapies. While advances in the treatment of PAH over the last two decades have markedly improved median survival from 2.8 years to approximately 9 years after diagnosis, PAH patients still face significant burdens from their disease and premature death. We estimate, based on publicly disclosed data, that the global PAH market was valued at $6.0 billion in 2018 and is expected to reach $10.0 billion by the end of 2025. Limitations of Current Therapies for PAH There is currently no cure for PAH. The three main classes of currently approved drugs for the treatment of PAH are all systemic vasodilators that directly modulate vasoconstrictive or vasodilatory pathways. These currently approved therapies for PAH focus on three distinct molecular pathways: the endothelin pathway, the nitric oxide pathway and the prostacyclin pathway. The classes of drugs that target these three pathways are: • • • Endothelin Receptor Antagonists. Endothelin receptor antagonists work by blocking the action of endothelin-1, a potent vasoconstrictor, thereby increasing blood flow to the lungs. These drugs, which are delivered orally, include bosentan and macitentan, marketed by Actelion as Tracleer and Opsumit, and ambisentan, marketed by Gilead as Letairis. Nitric Oxide Pathway Modulators. Nitric oxide is a naturally occurring molecule that is widely recognized as important in a number of biological processes. Nitric oxide causes blood vessels to relax and widen, resulting in an increase in blood flow. Oral drugs such as sildenafil, marketed by Pfizer as Revatio, and tadalafil, marketed by United Therapeutics as Adcirca, are phosphodiesterase type 5 inhibitors that work by enhancing the activity of naturally occurring nitric oxide. Prostacyclin Analogues and IP Prostacyclin Receptor Agonists. Patients with PAH have been shown to have reduced levels of prostacyclin, a naturally occurring substance that relaxes the pulmonary blood vessels, prevents platelet aggregation and inhibits the proliferation of smooth muscle cells in the pulmonary vessels. Prostacyclin analogues and IP prostacyclin receptor agonists, such as iloprost, treprostinil and selexipag, marketed by Bayer and Actelion as Ventavis, United Therapeutics as Remodulin and Actelion as Uptravi, respectively, mimic the effects of prostacyclin and are approved therapies for PAH. These drugs have been shown to improve exercise capacity, quality of life, pulmonary arterial pressure and short-term survival in PAH patients and suggest enhanced long-term survival based on observational studies. However, none of the 10 current treatments is curative and long-term prognosis remains poor. These therapies have a singular approach to treating PAH by modulating the vasoconstrictive or vasodilatory pathways but have limited ability to address other disease processes such as inflammation, cell proliferation, fibrosis and vascular remodeling. Furthermore, these drugs can cause hypotension, which can cause fainting and dizziness and can be life-threatening. As the disease progresses, additional vasodilator therapies are typically added to existing therapies rather than replacing drugs that are no longer providing sufficient benefit. Our Solution: PB1046 PB1046, a novel, subcutaneously-injected VIP analogue, is a recombinant fusion protein composed of VIP and our proprietary ELP technology. Based on the pharmacokinetic profile of PB1046 observed in our clinical trials, the fusion of VIP to ELP results in both a longer circulating half-life and a prolonged absorption profile, potentially enabling once-weekly dosing. We believe that, in addition to vasodilation, PB1046 may suppress the adverse remodeling of blood vessels and increase cardiac contractility and relaxation. PB1046 has been administered to more than 60 patients with hypertension or a history of cardiac disease in three Phase 1/2 clinical trials conducted in the United States with no drug-related SAEs to date. PB1046 Background VIP is a peptide hormone produced in many tissues throughout the body. Native VIP exerts its function in the body by binding to two distinct receptors: vasoactive intestinal peptide receptor 1, or VPAC1, and vasoactive intestinal peptide receptor 2, or VPAC2. As is the case for many other peptide hormones, the body uses VIP for distinct purposes in different locations. VPAC1 is found predominantly in the gastrointestinal tract, while VPAC2 is found predominantly in the myocardial wall and pulmonary arteries. VIP plays a key role in the relaxation of smooth muscles, which in turn leads to the dilation of blood vessels and to the lowering of arterial blood pressure. VIP also inhibits airway and pulmonary vascular smooth muscle cell proliferation and has broad anti-inflammatory properties, in addition to neutralizing a variety of pulmonary vasoconstrictors, including endothelin. We designed PB1046 using our ELP technology to harness the positive therapeutic effects of native VIP while addressing the drawbacks that make native VIP inappropriate for use as a direct therapy. Native VIP is rapidly degraded, and, when injected into the body, is eliminated within minutes, limiting its therapeutic effect. High levels of native VIP also result in severe gastrointestinal problems due to VPAC1 activation. We have used our ELP technology to extend the half-life of VIP in PB1046 to approximately 60 hours. In addition, we designed PB1046 to be active predominantly on VPAC2 rather than VPAC1 in order to preferentially affect the lung and cardiac tissue and reduce the potential for gastrointestinal side effects associated with VPAC1 activation. Clinical Development of PB1046 We have completed two clinical trials of subcutaneously-injected PB1046. In these trials, PB1046 was observed to be well tolerated, with no drug-related SAEs. In both trials, we observed that patients receiving PB1046 experienced reductions in blood pressure that were sustained for at least one week, with no reported episodes of symptomatic hypotension. PB1046 Phase 2b Clinical Trial We are conducting a randomized, double-blinded, controlled Phase 2b trial in approximately 60 patients with PAH who are New York Heart Association functional class II or III, with an open-label extension. In this trial, patients receive weekly subcutaneous injections of PB1046, in addition to their oral standard-of-care medications, for 16 weeks. These patients initially receive a dose of 0.2 mg/kg of PB1046, to be escalated and ultimately increased to a maximum dose of 2.0 mg/kg, as tolerated. Because in earlier clinical trials we have observed an association between PB1046 dosing and injection-site erythema, in lieu of a completely inactive placebo we instead use a blinded control that has a very low dose of PB1046 that is below a level likely to have therapeutic benefit, but still produces local vasodilation at the injection site in most subjects. The primary endpoint is the change in pulmonary vascular resistance as measured by invasive right heart catheterization. Secondary endpoints include six minute walk distance, respiratory function and biomarkers for cardiac function. Safety endpoints include incidence and severity of AEs and immunogenicity. Six minute walk distance is an important clinical endpoint that the FDA has previously used as the basis for approval of other PAH drugs. We have temporarily paused enrollment of new patients in this trial as a precaution to minimize potential exposure of this patient population at high risk of serious illness from COVID-19. However, we have also informed investigators that they may continue dosing PB1046 and performing assessments for current trial participants if they deem it appropriate and such activities are permitted by their respective institutions. Additionally, we continue to identify new trial sites for future initiation. Although we have been targeting to report results from this trial in the fourth quarter of 2020, we believe that the COVID-19 outbreak will temporarily prevent us from being able to initiate new trial sites and enroll new patients, likely delaying our ability to report the results of this trial into 2021. 11 Phase 1 Single Ascending Dose Clinical Trial We completed a single ascending dose Phase 1 clinical trial of subcutaneously injected PB1046 in 30 patients with hypertension to assess the safety and pharmacokinetics of PB1046 and to demonstrate early proof of concept. In this clinical trial, the patients stopped taking their standard-of-care anti-hypertensive medications for 14 days before receiving either placebo or a single ascending dose of PB1046 of between 0.05 mg/kg and 0.8 mg/kg. Consistent with our expectation for slow release of ELP fusion proteins, the half-life of PB1046 was approximately 60 hours and serum levels of PB1046 exhibited a prolonged pharmacokinetic profile extending to at least seven days following a single subcutaneous dose, as illustrated below. This is in contrast to the pharmacokinetics of native VIP in which serum levels of VIP disappear within minutes. We believe these results support once-weekly subcutaneous dosing of PB1046. Pharmacokinetics of single subcutaneous doses of PB1046 in a Phase 1 dose escalation trial The pharmacodynamic activity of PB1046 was assessed by measurements of changes in blood pressure. In the highest dose cohort, we observed that systolic and diastolic blood pressure in patients receiving PB1046 were reduced within one day and remained below levels seen in placebo- treated patients for seven days, as illustrated below. At seven days, all patients resumed their standard hypertension medications and subsequent blood pressures, and the magnitude of reduction in blood pressure compared to baseline were similar whether they had received PB1046 or placebo. Mean change in systolic blood pressure in a Phase 1 trial following single subcutaneous dose of PB1046 12 Phase 1b/2a Multiple Ascending Dose Clinical Trial We conducted a double-blinded, multiple ascending dose Phase 1b/2a trial in 29 patients with heart failure with reduced ejection fraction, or HFrEF, in order to assess the safety and long-acting pharmacokinetic and pharmacodynamic activity of subcutaneously injected PB1046 in patients with cardiovascular disease. In HFrEF, the heart muscle is not able to contract adequately and therefore expels less oxygen-rich blood into the body. In this clinical trial, patients remained on their standard-of-care heart failure medications and received either weekly placebo or weekly doses of PB1046 of between 0.2 mg/kg and 1.2 mg/kg for four weeks. This clinical trial reproduced the safety, pharmacokinetic and pharmacodynamic observations of the single-dose trial, and we observed that once-weekly dosing was well tolerated. No drug-related SAEs were reported, and there were no reported instances of hypotension, excluding mild orthostatic hypotension in four subjects, which did not appear to be dose related. Of the 22 subjects who received active study drug, all experienced injection-site erythema reaching severe toxicity due to the size of the erythema, and three subjects discontinued treatment due to the erythema. We observed that patients in the highest dose cohort had a statistically significant reduction in blood pressure compared to placebo that was sustained throughout the dosing period, with p-value of 0.043, as illustrated below. A result is considered to be statistically significant when the probability of the result occurring by random chance, rather than from the efficacy of the treatment, is sufficiently low. The conventional method for determining the statistical significance of a result is known as the “p-value,” which represents the probability that random chance caused the result (for example, a p-value = 0.01 means that there is a 1% probability that the difference between the control group and the treatment group is purely due to random chance). Generally, a p-value less than 0.05 is considered statistically significant. 13 Mean change in systolic blood pressure in a Phase 1b/2a trial following four weekly subcutaneous doses of PB1046 Based on the results of this clinical trial, and an assessment of a number of clinical and commercial factors, we determined that our initial indication for PB1046 would be PAH. Phase 1b/2a CardioMEMS Pilot Clinical Trial Prior to launching a large Phase 2b trial in patients with PAH, the FDA requested that we explore the safety and hemodynamics of PB1046 in patients with PAH. To achieve this objective, we initiated a pilot Phase 1b/2a clinical trial in a small population of PAH patients who had an implanted CardioMEMS device. The patients enrolled in this trial were difficult-to-treat patients with long histories of PAH who were no longer responding to their current therapies. These patients initially received a dose of 0.2 mg/kg of PB1046, which was escalated weekly as tolerated and could be increased to a maximum dose of 2.0 mg/kg, while remaining on their existing therapies. In the first two patients dosed in this clinical trial, we observed changes in parameters that are important to PAH patients, including that patients’ pulmonary arterial pressure and pulmonary resistance decreased over time while cardiac stroke volume and overall cardiac output increased. Results for one of the patients in this trial are illustrated below. The results from the second patient were generally consistent with this patient. These observations are consistent with our expectations for a VIP-based therapy. These patients had continued improvements over a period of 60 days, which we believe suggest that, in addition to its vasodilatory activity, PB1046 may also have more long-term effects on blood vessel and cardiac remodeling. These patients also opted into a trial protocol extension. 14 Representative CardioMEMS data from one PAH patient receiving weekly doses of PB1046 In subsequent discussions with the FDA, the safety profile of our Phase 1b/2a clinical trial and the available data from this pilot clinical trial were reviewed, and the FDA determined that our data were sufficient to enable initiation of a Phase 2b clinical trial. Accordingly, we do not intend to enroll additional patients in this pilot clinical trial. Safety Overview from Clinical Trials of PB1046 There were no drug-related SAEs reported for any of the patients who have received PB1046. When PB1046 was administered subcutaneously, it was almost always associated with a mild- to moderate- injection-site erythema, or patch of redness, which on average appeared at about 12 hours after injection. The injection-site erythema was not judged by the investigator to be an allergic type reaction; rather, in the investigator’s view, it was likely to be associated with the activity of VIP binding to receptors in the skin, resulting in local vasodilation. Additionally, 70% of patients receiving a subcutaneous injection of PB1046 experienced mild pain or tenderness at the injection site, which occurred hours to days after injection and on average lasted about one week. One-third of the patients also experienced mild pruritus, or itching, at the site of injection. We believe that these events are primarily due to the fused VIP peptide since similar events were not observed in clinical trials of other constructs that contain the ELP domain. None of the injection site reactions were judged to be serious. We observed a similar tolerability profile in the Phase 1 clinical trial of PB1046. Notably, there were no events of symptomatic hypotension related to PB1046 in any of the subjects who have received PB1046. Preclinical Studies Published independent research indicates that patients with PAH have both reduced levels of VIP in the lung and in circulation as well as increased levels of VPAC2 receptors in lung tissue. Mice bred to be VIP-deficient spontaneously express symptoms of moderately severe PAH. Repeated treatment of these mice with VIP corrected the key characteristics of the disease including right heart dysfunction, vascular remodeling and lung inflammation. In the monocrotaline-induced PAH rat model, an experimental model of PAH, VIP was active in preventing, and partially reversing, the symptoms of PAH. Combination therapy with VIP and the endothelin receptor antagonist bosentan was shown to be more active than either drug 15 alone. Furthermore, in multiple preclinical studies we have demonstrated the benefits of PB1046 in cardiomyopathies, due to its ability to induce heart contractility and relaxation effects without an increase in myocardial oxygen demand. Potential Applications of PB1046 in Other Indications The biological activities associated with VIP have the potential to provide therapeutic benefit to patients with other diseases. We believe that PB1046 provides a mechanism to bring these VIP-based therapies forward in the following indications: • • DMD-associated Cardiomyopathy. Cardiac dysfunction is a very common manifestation of DMD and a common cause of death for individuals with this condition. The ability of PB1046 to increase contractibility of cardiac muscles presents the possibility that it could provide therapeutic benefit to these patients. We observed that PB1046 slowed deterioration in cardiac function and preserved skeletal muscle function in a mouse model of DMD. In addition to direct effects on cardiac function, we believe decreased fibrosis also contributed to the positive effects of PB1046 on both cardiac and skeletal muscle in this model. The FDA has granted orphan drug designation for PB1046 for the treatment of cardiomyopathy associated with DMD. Cystic Fibrosis. VIP has been shown to stimulate the processing of the cystic fibrosis transmembrane regulator, or CFTR, the protein defective in patients with cystic fibrosis, or CF. In mice lacking the gene for VIP, CFTR is not located at the cell surface, where it is required to function properly, but accumulates within the cell. These mice have lung abnormalities that resemble CF and treatment with VIP peptide restored CFTR to the cell surface and corrected the lung tissue abnormalities. Treatment of human epithelial cells containing the most common CFTR mutation found in CF patients (F508del) with PB1046 in vitro has been observed to increase CFTR activity, providing further support that PB1046 may have potential as a treatment for patients with CF. PB6440 for Treatment-Resistant Hypertension PB6440 is a selective aldosterone synthase inhibitor that we are developing as an orally administered treatment for resistant hypertension. The mineralocorticoid hormone aldosterone is a critical regulator of fluid and electrolyte balance in the body and, as such, can play an important role in the development of high blood pressure or hypertension. Elevated aldosterone levels are associated with resistant hypertension, congestive heart failure and chronic kidney disease. Agents that block the action of mineralocorticoids at the receptor level, such as spironolactone, have been shown to lower blood pressure, including in patients with resistant hypertension. However, use of these agents is limited by adverse side effects. Inhibition of the production of aldosterone through inhibition of the enzyme responsible for its synthesis, aldosterone synthase (CYP11B2), is an alternative approach to treatment of hypertension. However, development of aldosterone synthase inhibitors is challenging because of a closely-related enzyme, steroid 11β-hydroxylase (CYP11B1), which many potential compounds also inhibit. In preclinical studies, PB6440 was observed to be a highly potent and selective inhibitor of aldosterone synthase and demonstrated a dose-dependent aldosterone reduction without a significant increase in 11-deoxycorticosterone or deoxycortisol in both rodent and primate models. The oral bioavailability and pharmacokinetic profiles appear suitable for once-daily oral dosing in humans. We currently plan to initiate clinical development of PB6440 pending the completion of nonclinical IND-enabling studies planned for 2020, which are expected to be followed by an IND filing and a first-in-human trial in early 2021. ELP Technology Our proprietary ELP technology is based on recombinant biopolymers called ELPs, which comprise individual subunits or building blocks derived from a five-amino acid repeat motif found in the human protein elastin. This five-amino acid motif is repeated multiple times to form the ELP biopolymer. We produce our ELP-based products by engineering E. coli to produce a single protein comprising the active peptide or protein fused to the ELP biopolymer. This molecule is active as a fusion protein and does not require cleavage or release of the peptide. ELP fusion proteins are produced in the soluble fraction of E. coli, which allows for ease of scale-up and purification. Fusion to ELPs significantly improves the stability of peptides and proteins and enables use of natural or minimally altered peptide sequences. We believe these fusion proteins retain similar potency to the native molecule while being protected from degradation by enzymes in circulation. Additionally, we have observed that the fusion protein maintains the solubility and long half-life of the ELP, in many cases allowing for long-term liquid stability, which is important for injectable products. 16 ELP fusion proteins can undergo a reversible phase transition, in which ELP fusion proteins aggregate and form a sustained-release depot under the skin. This phase transition is driven by changes in temperature. At lower temperatures ELP fusion proteins are completely soluble, while at warmer temperatures the ELP fusion proteins are in a gel-like state. This allows the ELP fusion proteins to be easily handled and administered subcutaneously using standard, fine gauge needles and syringes. Once the ELP fusion protein is exposed to body heat, it forms a drug depot that slowly releases soluble ELP fusion protein into circulation. By modifying the amino acid sequence of the individual subunits and by varying its overall length, we can engineer our ELP fusion proteins to be released on timescales extending to a week or longer. Product candidates based on our ELP technology, including prior product candidates for which we have ceased development in order to focus on the development of therapies for cardiopulmonary diseases, have been evaluated in over 500 patients with no known drug-related SAEs. Preclinical Programs We continue to invest in applying our ELP technology to the development of novel product candidates. Our focus is on peptides and proteins that are scientifically or clinically validated but where a suboptimal half-life, stability and delivery limit their potential therapeutic applications. Our more advanced ELP preclinical programs include: • • Glucagon-like peptide-2. Glucagon-like peptide-2, or GLP-2, stimulates growth of intestinal villi, increasing their ability to absorb nutrients. GLP-2 is a potential treatment for patients with short bowel syndrome, Crohn’s disease or mucositis in patients undergoing cancer treatment. Teduglutide, currently marketed under the brand name Gattex, is an FDA-approved therapy based on GLP-2 that requires daily injections. In animal models, our GLP-2-ELP product candidate provided sustained levels of GLP-2, resulting in greater efficacy than teduglutide with less frequent dosing. C-type natriuretic peptide. C-type natriuretic peptide, or CNP, is a regulator of bone growth and can rescue defects in fibroblast growth factor 3 that cause achondroplasia resulting in dwarfism. Native CNP has a half-life of less than three minutes, limiting its use as a direct therapeutic. We are developing our CNP-ELP product candidate to deliver therapeutic levels of CNP with once weekly subcutaneous injections. In a mouse model, we observed a demonstrated effect on linear growth when our CNP-ELP product candidate was injected once every four days.

In January 2020, in connection with our entering the SFJ Agreement, we entered into an amendment to the exclusive license agreement pursuant to which MedImmune consented to a potential assignment of the MedImmune License and transfer of our business related to PB2452 to SFJ in the event of the occurrence of certain program transfer events, should they ever occur. Co-Development Agreement for PB2452 with SFJ Pharmaceuticals In January 2020, we entered into the SFJ Agreement, pursuant to which SFJ will provide us funding to support the global development of PB2452 as a reversal agent for the antiplatelet drug ticagrelor in patients with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure. Under the SFJ Agreement, SFJ has agreed to pay us up to $120.0 million to support the clinical development of PB2452. SFJ paid us an initial $10.0 million in March 2020 after we obtained the consent of Silicon Valley Bank, or SVB, to grant SFJ a security interest in all of the assets owned or controlled by us that are necessary for the manufacture, use or sale of PB2452. SFJ will pay us an additional $80.0 million through cost reimbursements followed by six equal quarterly payments beginning with the quarter ending September 30, 2020 through the quarter ending December 31, 2021, and up to an additional $30.0 million upon the achievement of specified milestones with respect to our clinical development of PB2452. During the term of the SFJ Agreement, we will have primary responsibility for clinical development and regulatory activities for PB2452 in the United States and the European Union, while SFJ will have primary responsibility for clinical development and regulatory activities for PB2452 in China and Japan and will provide clinical trial operational support in the European Union. We have agreed to use commercially reasonable efforts to conduct and complete our Phase 3 clinical trial of PB2452 and to file a BLA or its foreign equivalent within specified timelines with each of the FDA and the European Medicines Agency, or the EMA. We have formed a joint steering committee with SFJ to oversee and manage the collaboration, including our Phase 3 program and the regulatory process. 18 Under the terms of the SFJ Agreement, following the FDA approval of a BLA for PB2452, we will pay SFJ an initial payment of $5.0 million and an additional $325.0 million in the aggregate in seven additional annual payments. If the EMA, or the national regulatory authority in certain European countries, authorizes a marketing approval for PB2452, we will pay SFJ an initial payment of $5.0 million and an additional $205.0 million in the aggregate in seven additional annual payments. If either the Pharmaceuticals and Medical Devices Agency of Japan, or the PMDA, or the National Medical Products Administration of China, or the NMPA, approves a marketing application for PB2452, we will pay SFJ an initial payment of $1.0 million and then an additional $59.0 million in the aggregate in eight additional annual payments. Within 120 days following approval of a BLA, or its equivalent, for PB2452 in one of the jurisdictions described above, we have the right, at our option, to make a one-time cash payment to SFJ to buy out all or a portion of the future unpaid approval payments for such jurisdiction (i.e., the U.S. Approval Payments, EU Approval Payments or Japan/China Approval Payments, as applicable) for a price reflecting a mid-single-digit discount rate. Within 120 days following a change of control of our company, we or our successor have the right, at its option, to make a one-time cash payment to SFJ to buy out all or a portion of the future unpaid approval payments in any of the jurisdictions in which a BLA, or its equivalent, for PB2452 was approved prior to the change of control for a price reflecting a mid-single-digit discount rate, provided that SFJ has not previously assigned the right to receive such payments to a third party, in which event we or our successor shall not have such right. Under the SFJ Agreement, we granted SFJ a security interest in all of the assets we own or control that are necessary for the manufacture, use or sale of PB2452, or PB2452 Intellectual Property. In connection with the grant of the security interest, we agreed to certain affirmative and negative covenants, including restrictions on our ability to pay dividends, incur additional debt or enter into licensing transactions with respect to the PB2452 Intellectual Property. In addition, we agreed that the security interest granted to SFJ will be a first-priority security interest, subject only to the lien of SVB for our existing indebtedness to SVB. Upon execution of the SFJ Agreement, we issued to SFJ a ten-year warrant exercisable for 2,200,000 shares of our common stock at an exercise price per share of $6.50. The warrant is exercisable as follows: (i) 1,100,000 shares may be exercised at any time after the effective date of the SFJ Agreement, provided that SFJ may not sell such exercised shares until one year after such effective date, and (ii) the remaining 1,100,000 shares may be exercised at any time at SFJ’s election if the results of our Phase 3 trial meet the interim primary endpoint as set forth in the Phase 3 trial protocol. In the event that (i) we fail to pay any amounts payable to SFJ under the SFJ Agreement within a specified time period, (ii) we are in default of our obligations, subject to certain exclusions, under the MedImmune License, or (iii) either (a) we determine it is probable that we will be unable to meet our obligations as they become due within one year after the date that our financial statements for the then-current quarter are issued, or available to be issued or (b) a “going concern” footnote is included in any of our financial statements, and, in either case ((a) or (b)), we fail to remedy such going concern condition as specified in the SFJ Agreement, SFJ may elect to have our business related to PB2452 transferred to SFJ. We refer to such events (i), (ii) or (iii) as the Potential Program Transfer Events. If our business related to PB2452 is transferred to SFJ, we will not share in any revenues from the commercialization of PB2452 until SFJ has received a 300% return on its investment in PB2452, after which we will be entitled to a mid-single-digit royalty on net sales of PB2452 in the United States and certain European countries, and after SFJ has received an aggregate 500% return on its investment in PB2452, we will be entitled to a mid-single-digit royalty on net sales of PB2452 in the rest of the world. The SFJ Agreement expires upon the payment of all approval payments owing to SFJ, unless earlier terminated. The SFJ Agreement may be terminated by us at will at any time after SFJ has paid or incurred a total of $60.0 million of PB2452 development costs and before receipt of any BLA, or its equivalent, approval for PB2452 from the FDA, the EMA, the PMDA or the NMPA. SFJ may terminate the SFJ Agreement (i) upon the occurrence of a material adverse event, as defined in the SFJ Agreement, (ii) upon a change of control of us, (iii) if (a) we are enjoined from further developing or commercializing PB2452 in any of the United States, certain European countries, China, Japan or Hong Kong or (b) the future value of PB2452 is materially adversely affected due to (1) certain third-party patents that would be infringed by the manufacture, use, sale, offer for sale or import of PB2452 in any of the United States, certain European countries or China, Japan or Hong Kong or (2) invalidity or unenforceability of all patent rights controlled by us covering PB2452 as a reversal agent for the antiplatelet drug ticagrelor in patients with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure in any of the United States, certain European countries, Japan, China or Hong Kong, we refer to each of (a) and (b) as an Adverse Patent Impact, if we do not cure the Adverse Patent Impact within six months of notice from SFJ, or (iv) if SFJ disagrees with certain decisions made by us as part of the joint steering committee. The SFJ Agreement may be terminated by either party (i) upon a material breach of the SFJ Agreement by the other party, (ii) if PB2452 fails to receive regulatory approval from at least one of the FDA, the EMA, the PMDA or the NMPA after completion of the Phase 3 trial of PB2452, submission of BLAs, or their equivalents, to such agencies and the use of commercially reasonable efforts to obtain approval of such BLAs, or their equivalents, (iii) if the Phase 3 trial of PB2452 is completed or terminated and either (a) the primary endpoint in the Phase 3 trial is not achieved or (b) SFJ reasonably determines that the results of the trial do not support 19 regulatory approval, (iv) upon the bankruptcy of the other party, (v) if the independent data monitoring committee for the Phase 3 trial of PB2452 recommends termination of the trial for safety or health reasons or for futility or the parties mutually agree that a material health or safety concern exists, or (vi) upon a breach by the other party involving improper payments or a violation of anti-corruption policies, unless such breach can be cured without having a materially adverse impact on the probability of completing clinical trials of PB2452 or obtaining regulatory approval for PB2452. In certain instances, upon the termination of the SFJ Agreement, we will be obligated to pay SFJ a multiple of the amounts paid or incurred by SFJ under the SFJ Agreement, including specifically: • • • • 300% of such amounts (1) in the event that SFJ terminates the SFJ Agreement due to a material uncured breach of the SFJ Agreement by us or our bankruptcy, (2) if we terminate the SFJ Agreement at will prior to the first regulatory approval of PB2452, or (3) if the SFJ Agreement is terminated due to a safety concern and such termination either (a) arose from our gross negligence, or (b) is due to a serious safety issue that was known to us on the date of the SFJ Agreement but the data demonstrating such serious safety issue were not disclosed to SFJ or publicly known prior to the date of the SFJ Agreement; 150% of such amounts if SFJ terminates the SFJ Agreement (1) upon a change of control of us or (2) upon a breach involving improper payments or a violation of anti-corruption policies by us, unless such breach can be cured without having a materially adverse impact on the probability of completing clinical trials of PB2452 or obtaining regulatory approval for PB2452; 100% of such amounts in the event of a termination due to an Adverse Patent Impact; and 100% of such amounts (plus an amount reflecting interest on such amounts) at an annual rate of 25% in the event of termination by SFJ due to disagreement with certain decisions made by us as part of the joint steering committee. In addition, if following termination of the SFJ Agreement we continue to develop PB2452 and obtain BLA, or its equivalent, approval in the United States, the European Union, Japan or China, we will make the applicable approval payments for such jurisdiction to SFJ as if the SFJ Agreement had not been terminated, less any payments made upon termination, except that if we terminate the SFJ Agreement for SFJ’s failure to make any payment to us when due, or SFJ terminates the SFJ Agreement due to a material adverse event, as defined in the SFJ Agreement, then our obligation to make such approval payments would be reduced by 50%. Duke License Agreement In October 2006, we entered into an exclusive license agreement, which was most recently amended in April 2019, with Duke, or the Duke License. Pursuant to the Duke License, Duke granted to us an exclusive, worldwide license under certain patent rights owned or controlled by Duke, and a non-exclusive, worldwide license under certain know-how of Duke, to develop and commercialize any products or processes covered by the Duke License, or the Duke licensed products, relating to ELPs. The in-licensed patent rights are generally directed to providing extended exposure for proteins and peptides administered through subcutaneous injections and include 13 registered patents in the United States, 12 registered patents in foreign jurisdictions, four pending patent applications in the United States and six pending foreign applications. The last patent is expected to expire in 2030 without extension. We have the right to sublicense the Duke licensed products to third parties subject to certain conditions specified in the Duke License. In May 2017, certain patent rights under the Duke License reverted to Duke, and Duke subsequently granted to us a non-exclusive license under such patent rights to develop and commercialize any products or processes involving such patent rights. We also granted back to Duke an exclusive sublicense under certain patent rights licensed to us under the Duke License and a non-exclusive license under certain patent rights owned or controlled by us, in each case to exploit compounds developed using our proprietary ELP technology. Under the terms of the Duke License, we have paid or are required to pay: • • • • an upfront fee of $37,000; amendment fees of $0.2 million related to subsequent amendments of the Duke License; additional licensing fees of $0.2 million; up to $2.2 million in clinical and regulatory milestone fees; 20 • • • up to $0.4 million in commercial milestone fees; low single-digit royalty percentages on net sales of Duke licensed products, with minimum aggregate royalty payments of $0.2 million payable following our achievement of certain commercial milestones; and up to the greater of $0.3 million or a low double-digit percentage of the fees we receive from a third party in consideration of forming a strategic alliance with respect to certain patent rights covered under the Duke License. In consideration for license rights granted to us, we initially issued Duke 24,493 shares of our common stock. Until we reached a certain stipulated equity milestone, which we reached in October 2007, we were obligated to issue additional shares of common stock to Duke from time to time so that its aggregate ownership represented 7.5% of our issued and outstanding capital stock. From the inception of the Duke License through December 31, 2019, we have incurred royalty costs of $0.3 million under the Duke License. As of May 2017, Duke is required to pay us a percentage of revenue that it receives from granting a license or sublicense with respect to certain products covered under the Duke License. As of December 31, 2019, Duke has not paid us any of such fees. We also must pay Duke the first $1.0 million of non- royalty payments we receive from a sublicensee, and thereafter a low double-digit percentage of any additional non-royalty payments we receive. The Duke License requires us to use commercially reasonable efforts to develop, obtain and maintain regulatory approval for and commercialize the Duke licensed products according to a particular development schedule throughout the term of the Duke License. We are required to apply for, prosecute and maintain all United States and foreign patent rights under the Duke License. In addition, our rights under the Duke License are not assignable without the prior written consent of Duke, except to a third-party acquirer by our merger or sale of our stock or assets, or to an affiliate of our company. Unless earlier terminated, the Duke License automatically expires on the date on which all patent rights granted under the Duke License expire, or upon our bankruptcy, insolvency or certain similar occurrences. The Duke License may be terminated prior to its expiration: • • • • • by mutual written consent of us and Duke; by us upon three months’ written notice to Duke; by either party upon the other party’s illegal conduct or guilty plea with respect to intentional fraud, willful misconduct or felony; by either party upon the other party’s material breach of the Duke License that is not cured within the specified cure period based on the nature of such breach; and by Duke upon our decision to cease commercial development of the patent rights covered by the Duke License for a material period of time. Upon termination of the Duke License, we grant to Duke an exclusive, royalty-free, sublicensable license under our patent rights and know- how to use any intellectual property developed by us in the course of exercising our rights under the Duke License. Viamet Asset Purchase Agreement In January 2020, we entered into an asset purchase agreement, or the PB6440 Agreement, with Viamet Pharmaceuticals Holdings, LLC and its wholly-owned subsidiary, Selenity Therapeutics (Bermuda), Ltd., or the Sellers, pursuant to which we acquired all of the assets and intellectual property rights related to PB6440, the Sellers’ proprietary CYP11B2 inhibitor compound (formerly known as SE-6440 or VT-6440) and certain other CYP11B2 inhibitor compounds that are covered by the patent rights acquired by us under the PB6440 Agreement, or together, the Compounds. The acquired patent rights include 19 issued or pending United States and foreign patents and patent applications, with the last issued patent acquired expected to expire in 2037. Under the terms of the PB6440 Agreement, we paid the Sellers an upfront fee of $0.1 million upon the closing of the transaction, and we are required to pay the Sellers up to $5.1 million upon the achievement of certain development and intellectual property milestones with respect to certain product candidates that contain a Compound, up to $142.5 million upon the achievement of certain commercial milestones with respect to any approved product that contains a Compound, and low- to mid-single digit royalty percentages on the net sales of approved products that contain a Compound, subject to customary reductions and offsets in specified circumstances. 21 Manufacturing Our large molecule clinical and preclinical product candidates PB2452, PB1046 and our ELP preclinical and research and development pipeline candidates are currently manufactured using a microbial expression system. Our manufacturing utilizes a straight-forward E. coli fermentation process with a simple column chromatography-based purification process. Our small molecule candidate, PB6440 is manufactured through chemical synthesis. We believe that these manufacturing processes will enable our product candidates to be manufactured efficiently for clinical and commercial applications. We do not have any cGMP manufacturing facilities. Instead, we utilize third parties for the cGMP manufacture of our product candidates for clinical trials, and we intend to continue to use third parties in the near term for the future clinical development and, if they are approved, commercial manufacture of our drug products. Our contract manufacturers are FDA-inspected establishments that have a history of supplying products to the pharmaceutical industry in accordance with cGMP. PB2452 PB2452 bulk drug substance, provided to us pursuant to the MedImmune License, was filled and released for use in our initial clinical trials. The PB2452 drug substance was manufactured by Wacker Biotech GmbH, or Wacker, a third-party contract manufacturer, utilizing Wacker’s proprietary E. coli strain. Manufacturing has continued at Wacker to generate drug supply for our ongoing clinical trials. We have also engaged BioVectra, Inc., or BioVectra, to serve as our contract manufacturer of PB2452 for our ongoing clinical trials. We intend to engage BioVectra for commercial-scale production of PB2452, if approved. As we advance PB2452 through clinical development, we may establish additional supply agreements for the manufacture of PB2452 in order to meet our expected needs for potential commercial demand. PB1046 and our ELP Preclinical Pipeline To date, we have relied on a non-proprietary E. coli strain for the production of PB1046 and our preclinical ELP pipeline candidates. Third- party manufacturers have performed the cGMP manufacturing of the drug product. Due to efficiencies achieved to date, we intend to utilize this non- proprietary strain for future manufacturing. As we advance PB1046 and other preclinical product candidates through development, we intend to establish additional supply agreements and/or technology transfer agreements in order to meet our expected needs for future clinical trials and potential commercial demand. PB6440 PB6440 is a small molecule candidate manufactured through chemical synthesis. Third-party manufacturers will perform the cGMP manufacturing of the drug. As we advance PB6440 through development, we intend to establish additional supply agreements and/or technology transfer agreements in order to meet our expected needs for future clinical trials and potential commercial demand. Sales and Marketing We retain worldwide commercial rights to all of our product candidates. Given our stage of development, we have not yet established a commercial organization or distribution capabilities. We intend to commercialize PB2452, if approved, independently in the United States because we believe the patient populations and medical specialists for these indications are sufficiently concentrated to allow us to effectively promote these products with a targeted sales team. We may explore, and selectively pursue, strategic collaborations or partnerships with third parties to commercialize PB1046, if approved, in the United States and any approved products outside of the United States in order to maximize the commercial potential of our products. Competition The pharmaceutical industry is subject to rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. We face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions, governmental agencies and public and private research institutions. Any product candidates that we successfully develop and commercialize will compete with existing treatments and new treatments that may become available in the future. Our current and potential future competitors have significantly more experience commercializing drugs that have been approved for marketing. Mergers and acquisitions in the pharmaceutical and biotechnology industries could result in even more resources being concentrated among a small number of our competitors. Accordingly, our competitors may be more successful than us in obtaining regulatory approval for therapies and in achieving widespread market acceptance of their drugs. 22 It is also possible that the development of a cure or more effective treatment method for the disorders we are targeting by a competitor could render our current or future drug candidates non-competitive or obsolete or reduce the demand for our drug candidates before we can recover our development and commercialization expenses. PB2452 There are currently no other known reversal agents approved or in clinical development for ticagrelor or any other antiplatelet drugs. In the European Union, an extracorporeal whole blood purification adsorber device is available that may be useful for non-specific removal of ticagrelor during some cardiac procedures when used in conjunction with cardiopulmonary bypass. Upon approval, PB2452 would be the only therapeutic agent available for specific reversal of ticagrelor. As a result, market acceptance of PB2452, if approved, will depend heavily on the continued market acceptance and use of ticagrelor. Ticagrelor competes against other commercially available antiplatelet therapies, including other P2Y12 receptor antagonists, many of which are available as generic drugs and are therefore currently significantly less expensive than ticagrelor. New antiplatelet therapies may also be developed in the future, including other reversible P2Y12 receptor antagonists and other antiplatelet therapies, which could also have reversal agents, that could displace ticagrelor as the preferred antiplatelet agent for ACS. PB1046 Although we anticipate that PB1046 may be used as a complement to patients’ existing therapies, we expect to compete with existing treatments for PAH patients with class II through class IV symptoms that target the endothelin, nitric oxide and prostacyclin pathways, as well as any generic equivalents that may be developed. In addition to currently approved drugs within these classes, we are also aware of a number of PAH therapies in clinical development, including: • • • • • • • • • • • Ralinepag, an oral IP prostacyclin receptor agonist being developed by Arena Pharmaceuticals; Trevyent, a formulation of treprostinil being developed by United Therapeutics; Bardoxolone methyl, an oral therapy being developed by Reata Pharmaceuticals for connective tissue disease-associated PAH; LIQ861, a powder formulation of treprostinil designed for deep-lung delivery using a disposable, dry powder inhaler being developed by Liquidia Technologies; CAM2043, a liquid crystal gel formulation of treprostinil as a once-weekly subcutaneous depot injection being developed by Camurus; Treprostinil Technosphere, an inhaled, dry powder formulation of treprostinil being developed by MannKind Corporation; Beraprost sodium 314d modified release, a single isomer oral prostacyclin analogue being developed by Lung Biotechnology PBC; Sotatercept, being developed by Acceleron; GB002, being developed by Gossamer Bio; INS1009, an inhaled nanoparticle formulation of a treprostinil prodrug being developed by Insmed Incorporated; and INOpulse, inhaled nitric oxide being developed by Bellerophon Therapeutics. PB6440 Although we anticipate that PB6440 may be used as a complement to patients’ existing antihypertensive therapies, we expect to compete with existing generic treatments for hypertension that target the mineralocorticoid receptor. In addition to the currently approved mineralocorticoid receptor antagonists, eplerenone and spironolactone, we are also aware of a number of therapies in clinical development for the treatment of resistant hypertension with which PB6440 would compete if approved including: • • Aprocitentan, orally active dual endothelin receptor antagonist that is being developed by Janssen Biotech; Firibastat, a selective and specific inhibitor of Aminopeptidase A being developed by Quantum Genomics; and 23 • CIN-107, an aldosterone synthase inhibitor being developed by Cincor Pharmaceuticals. Intellectual Property Our commercial success depends in part upon our ability to obtain and maintain proprietary protection for PB2452, PB1046, PB6440 and future product candidates and related discoveries and our ELP technology; to operate without infringing on or otherwise violating the proprietary rights of others; and to prevent others from infringing or otherwise violating our proprietary rights. We seek to protect our proprietary position by, among other methods, filing United States and foreign patent applications related to our ELP technology, our product candidates and other proprietary technologies, inventions and improvements that are important to the development and implementation of our business. We also rely on trademarks, trade secrets, know- how, continuing technological innovation and potential in-licensing opportunities to develop and maintain our proprietary position. The term of individual patents varies depending on the date of filing of the patent application and the legal term of patents in the countries in which they are obtained. Generally, patents issued from regularly filed applications in the United States are granted a term of 20 years from the earliest filing date of a non-provisional application. In addition, in certain instances, a patent term can be adjusted to recapture a portion of the delay by the United States Patent and Trademark Office in issuing the patent. In addition, a patent term may be extended to recapture a portion of the patent term effectively lost as a result of the FDA regulatory review period of the drug covered by the patent. The patent term extension based upon delay by the FDA can be up to five years beyond the expiration of the patent, but cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval and the extension may only apply to one patent that covers the approved drug (and to only those patent claims covering the approved drug or a method for using it). There can be no assurance that any such patent term adjustment or extension will be obtained. The duration of foreign patents varies in accordance with provisions of applicable local law, but typically in countries that we file, the patent term is 20 years from the earliest filing date of a non- provisional patent application. However, the actual protection afforded by a patent varies on a product-by-product basis and from country to country and depends upon many factors, including the type of patent, the scope of its coverage, the availability of regulatory-related extensions, the availability of legal remedies in a particular country and the validity and enforceability of the patent. Furthermore, we rely upon trade secrets, know-how and continuing technological innovation to develop and maintain our competitive position. We seek to protect our proprietary information, in part, using confidentiality agreements with our commercial partners, collaborators, employees and consultants and invention assignment agreements with our employees. We also have confidentiality agreements or invention assignment agreements with our commercial partners and selected consultants. These agreements are designed to protect our proprietary information and, in the case of the invention assignment agreements, to grant us ownership of technologies that are developed through a relationship with a third party. These agreements may be breached and we may not have adequate remedies for any such breach. In addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our commercial partners, collaborators, employees and consultants use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions. As of December 31, 2019, our patent estate contained at least 19 patent families that we own or in-license that protect various aspects of our ELP technology or our product candidates. We own or have rights in 22 United States patents, over 18 United States patent applications, over 60 foreign patents and over 60 foreign patent applications. PB2452 With regard to PB2452, we in-licensed one patent family. As of December 31, 2019, this patent family includes two issued United States patents with composition of matter claims covering PB2452 that are expected to expire in 2035 and 2036 without taking patent term extensions into account, three pending United States patent applications and 13 pending foreign applications, that if issued, would expire in 2035. PB1046 As of December 31, 2019, our portfolio of owned and in-licensed patents and patent applications relating to PB1046 consists of six issued patents in the United States, five pending applications in the United States, 48 granted foreign patents and 16 pending foreign applications with claims directed to compositions of matter covering PB1046 and methods of use thereof, including use in PAH, cystic fibrosis and cardiomyopathy associated with DMD, that we expect to expire between 2027 and 2036, without taking patent term extensions into account. 24 PB6440 Upon acquiring the intellectual property rights of PB6440 in January 2020, we acquired three patent families relating to aldosterone synthase inhibitors, which consist of two granted patents in the United States, two pending applications in the United States and 14 pending foreign applications. The granted United States patents are expected to expire in 2037 without taking patent term extensions into account. ELP Technology As of December 31, 2019, we owned two patent families relating to our ELP technology, which consist of one granted patent in the United States, one pending application in the United States and six pending foreign applications. The granted patent expires in 2021 without taking patent term extensions into account. Government Regulation and Product Approval The FDA and other regulatory authorities at federal, state and local levels, as well as in foreign countries, extensively regulate, among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, post-approval monitoring and post-approval reporting of biologics such as those we are developing. We, along with third-party contractors, will be required to navigate the various preclinical, clinical and commercial approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval or licensure of our product candidates. The process required by the FDA before biologic product candidates may be marketed in the United States generally involves the following: • • • • • • • • • completion of preclinical laboratory tests and animal studies performed in accordance with the FDA’s Good Laboratory Practices, or GLP, regulation; submission to the FDA of an IND, which must become effective before clinical trials may begin and must be updated annually or when significant changes are made; approval by an independent Institutional Review Board, or IRB, or ethics committee at each clinical site before the trial is commenced; performance of adequate and well-controlled human clinical trials to establish the safety, purity and potency of the proposed biologic product candidate for its intended purpose; preparation of and submission to the FDA of a BLA after completion of all pivotal clinical trials; satisfactory completion of an FDA Advisory Committee review, if applicable; a determination by the FDA within 60 days of its receipt of a BLA to file the application for review; satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the proposed product is produced to assess compliance with cGMP and to assure that the facilities, methods and controls are adequate to preserve the biological product’s continued safety, purity and potency and of selected clinical investigation sites to assess compliance with Good Clinical Practices, or GCP; and FDA review and approval of the BLA to permit commercial marketing of the product for particular indications for use in the United States. Preclinical and Clinical Development Prior to beginning the first clinical trial with a product candidate, we must submit an IND to the FDA. An IND is a request for authorization from the FDA to administer an investigational new drug product to humans. The central focus of an IND submission is on the general investigational plan and the protocol(s) for clinical studies. The IND also includes results of animal and in vitro studies assessing the toxicology, pharmacokinetics, pharmacology and pharmacodynamic characteristics of the product; chemistry, manufacturing and controls information; and any available human data or literature to support the use of the investigational product. An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises safety concerns or questions about the proposed clinical trial. In such a case, the IND may be placed on clinical hold and the IND sponsor and the 25 FDA must resolve any outstanding concerns or questions before the clinical trial can begin. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical trial. Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in accordance with GCPs, which include the requirement that all research subjects provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments. Furthermore, an independent IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial and its informed consent form before the clinical trial begins at that site and must monitor the trial until completed. Regulatory authorities, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some trials also include oversight by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board, which provides authorization for whether or not a trial may move forward at designated check points based on access to certain data from the trial and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. There are also requirements governing the reporting of ongoing clinical trials and clinical trial results to public registries. For purposes of BLA approval, human clinical trials are typically conducted in three sequential phases that may overlap. • • • Phase 1—The investigational product is initially introduced into healthy human subjects or patients with the target disease or condition. These studies are designed to test the safety, dosage tolerance, absorption, metabolism and distribution of the investigational product in humans, the side effects associated with increasing doses and, if possible, to gain early evidence on effectiveness. Phase 2—The investigational product is administered to a limited patient population with a specified disease or condition to evaluate the preliminary efficacy, optimal dosages and dosing schedule and to identify possible adverse side effects and safety risks. Multiple Phase 2 clinical trials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials. Phase 3—The investigational product is administered to an expanded patient population to further evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the investigational product and to provide an adequate basis for product approval. In some cases, the FDA may require, or companies may voluntarily pursue, additional clinical trials after a product is approved to gain more information about the product. These so-called Phase 4 studies may be made a condition to approval of the BLA. Concurrent with clinical trials, companies may complete additional animal studies and develop additional information about the biological characteristics of the product candidate and must finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, must develop methods for testing the identity, strength, quality and purity of the final product or, for biologics, the safety, purity and potency. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life. BLA Submission and Review Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development, nonclinical studies and clinical trials are submitted to the FDA as part of a BLA requesting approval to market the product for one or more indications. The BLA must include all relevant data available from pertinent preclinical and clinical studies, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls and proposed labeling, among other things. The submission of a BLA requires payment of a substantial application user fee to FDA, unless a waiver or exemption applies. Once a BLA has been submitted, the FDA’s goal is to review standard applications within ten months after it accepts the application for filing or, if the application qualifies for priority review, six months after the FDA accepts the application for filing. In both standard and priority reviews, the review process is often significantly extended by FDA requests for additional information or clarification. The FDA reviews a BLA to determine, among other things, whether a product is 26 safe, pure and potent and the facility in which it is manufactured, processed, packed or held meets standards designed to assure the product’s continued safety, purity and potency. The FDA may convene an advisory committee to provide clinical insight on application review questions. Before approving a BLA, the FDA will typically inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or its drug substance will be produced, the FDA may issue an approval letter or a Complete Response letter. An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications. A Complete Response letter will describe all of the deficiencies that the FDA has identified in the BLA, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA may issue the Complete Response letter without first conducting required inspections, testing submitted product lots and/or reviewing proposed labeling. In issuing the Complete Response letter, the FDA may recommend actions that the applicant might take to place the BLA in condition for approval, including requests for additional information or clarification. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of a product. If regulatory approval of a product is granted, such approval will be granted for particular indications and may entail limitations on the indicated uses for which such product may be marketed. For example, the FDA may approve the BLA with a Risk Evaluation and Mitigation Strategy, or REMS, to ensure the benefits of the product outweigh its risks. A REMS is a safety strategy to manage a known or potential serious risk associated with a product and to enable patients to have continued access to such medicines by managing their safe use and could include medication guides, physician communication plans or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace. The FDA may require one or more Phase 4 post-marketing studies and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization and may limit further marketing of the product based on the results of these post-marketing studies. Accelerated Approval Program Any marketing application for a biologic submitted to the FDA for approval may be eligible for FDA programs intended to expedite the FDA review and approval process, such as priority review and accelerated approval. A product is eligible for priority review if it has the potential to provide a significant improvement in the treatment, diagnosis or prevention of a serious disease or condition compared to marketed products. For biologic products, priority review designation means the FDA’s goal is to take action on the marketing application within six months of the 60-day filing date (compared with ten months under standard review). Additionally, products studied for their safety and effectiveness in treating serious or life-threatening diseases or conditions may receive accelerated approval upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity or prevalence of the condition and the availability or lack of alternative treatments. As a condition of accelerated approval, the FDA will generally require the sponsor to perform adequate and well-controlled post-marketing clinical studies to verify and describe the anticipated effect on irreversible morbidity or mortality or other clinical benefit. In addition, the FDA currently requires as a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch of the product. Priority review and accelerated approval do not change the standards for approval but may expedite the development or approval process. Orphan Drug Designation 27 Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, which is a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States for which there is no reasonable expectation that the cost of developing and making available in the United States a drug or biologic for this type of disease or condition will be recovered from sales in the United States for that drug or biologic. Orphan drug designation must be requested before submitting a BLA. After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. The orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review or approval process. If a product that has orphan drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan drug exclusive approval (or exclusivity), which means that the FDA may not approve any other applications, including a full BLA, to market the same drug or biologic for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity. Orphan drug exclusivity does not prevent FDA from approving a different drug or biologic for the same disease or condition or the same drug or biologic for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the BLA application fee. A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. In addition, exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition. Breakthrough Therapy Designation To qualify for the Breakthrough Therapy program, product candidates must be intended to treat a serious or life-threatening disease or condition and preliminary clinical evidence must indicate that such product candidates may demonstrate substantial improvement on one or more clinically significant endpoints over existing therapies. The FDA will seek to ensure the sponsor of a Breakthrough Therapy product candidate receives: intensive guidance on an efficient drug development program; intensive involvement of senior managers and experienced staff on a proactive, collaborative and cross-disciplinary review; and rolling review. Breakthrough Therapy designation does not change the standards for approval but may expedite the development or approval process. Post-Approval Requirements Any products manufactured or distributed by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to record-keeping, reporting of adverse experiences, periodic reporting, product sampling and distribution and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review and approval. There also are continuing user fee requirements, under which FDA assesses an annual program fee for each product identified in an approved BLA. Biologic manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Changes to the manufacturing process are strictly regulated and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance. The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including AEs of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things: • • restrictions on the marketing or manufacturing of a product, complete withdrawal of the product from the market or product recalls; fines, warning letters or holds on post-approval clinical studies; 28 • • • refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of existing product approvals; product seizure or detention, or refusal of the FDA to permit the import or export of products; or injunctions or the imposition of civil or criminal penalties. The FDA closely regulates the marketing, labeling, advertising and promotion of biologics. A company can make only those claims relating to safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. Physicians may prescribe legally available products for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturer’s communications on the subject of off-label use of their products. Biosimilars and Reference Product Exclusivity The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, the ACA, signed into law in 2010, includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or the BPCIA, which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-approved reference biological product. To date, a number of biosimilars have been licensed under the BPCIA, and numerous biosimilars have been approved in Europe. The FDA has issued several guidance documents outlining an approach to review and approval of biosimilars. Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity and potency, can be shown through analytical studies, animal studies and a clinical study or studies. Interchangeability requires that a product is biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product in any given patient and, for products that are administered multiple times to an individual, the biologic and the reference biologic may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic. Complexities associated with the larger, and often more complex, structures of biological products, as well as the processes by which such products are manufactured, pose significant hurdles to implementation of the abbreviated approval pathway that are still being worked out by the FDA. Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing that applicant’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of its product. The BPCIA also created certain exclusivity periods for biosimilars approved as interchangeable products. At this juncture, it is unclear whether products deemed “interchangeable” by the FDA will, in fact, be readily substituted by pharmacies, which are governed by state pharmacy law. The BPCIA is complex and continues to be interpreted and implemented by the FDA. In addition, recent government proposals have sought to reduce the 12-year reference product exclusivity period. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact, implementation and impact of the BPCIA is subject to significant uncertainty. Federal and State Fraud and Abuse, Data Privacy and Security and Transparency Laws and Regulations In addition to FDA restrictions on marketing of pharmaceutical products, federal and state healthcare laws and regulations restrict business practices in the biopharmaceutical industry. These laws may impact, among other things, our current and future business operations, including our clinical research activities and proposed sales, marketing and education programs and constrain the business or financial arrangements and relationships with healthcare providers and other parties through which we market, sell and distribute our products for which we obtain marketing approval. These laws include anti-kickback and false claims laws and regulations, data privacy and security and transparency laws and regulations, including, without limitation, those laws described below. 29 The federal Anti-Kickback Statute prohibits, among other things, individuals or entities from knowingly and willfully offering, paying, soliciting or receiving remuneration, directly or indirectly, overtly or covertly, in cash or in kind to induce or in return for purchasing, leasing, ordering or arranging for or recommending the purchase, lease or order of any item or service reimbursable under Medicare, Medicaid or other federal healthcare programs. The term “remuneration” has been broadly interpreted to include anything of value. The federal Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers and formulary managers on the other hand. Although there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor. In addition, a person or entity does not need to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation. Further, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act and the civil monetary penalties statute. The federal civil and criminal false claims laws, including the False Claims Act, which prohibit, among other things, any individual or entity from knowingly presenting or causing to be presented, a false claim for payment to the federal government or knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal government. A claim includes “any request or demand” for money or property presented to the United States government. Several pharmaceutical and other healthcare companies have been prosecuted under these laws for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of products for unapproved, and thus non- reimbursable, uses. The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created additional federal criminal statutes that prohibit, among other things, knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private third-party payors and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their respective implementing regulations, impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization on certain health plans, healthcare clearinghouses and certain healthcare providers, known as covered entities, and their respective business associates, independent contractors that perform certain services involving the use or disclosure of individually identifiable health information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA and seek attorneys’ fees and costs associated with pursuing federal civil actions. The federal Physician Payments Sunshine Act requires certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, to report annually to the Centers for Medicare & Medicaid Services, or CMS, information related to payments or other transfers of value made to physicians and teaching hospitals and applicable manufacturers and applicable group purchasing organizations to report annually to CMS ownership and investment interests held by physicians and their immediate family members. We may also be subject to state and foreign law equivalents of each of the above federal laws; state laws that require manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government or that otherwise restrict payments that may be made to healthcare providers; state and local laws that require the registration of pharmaceutical sales representatives; as well as state and foreign laws that govern the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts. Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. Because of the breadth of these laws and the narrowness of the statutory 30 exceptions and regulatory safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participating in government funded healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, contractual damages, reputational harm and the curtailment or restructuring of our operations. To the extent that any of our products are sold in a foreign country, we may be subject to similar foreign laws and regulations, which may include, for instance, applicable post-marketing requirements, including safety surveillance, anti-fraud and abuse laws and implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals. We are also subject to additional federal laws, such as the United States Foreign Corrupt Practices Act, or the FCPA, which prohibits, any United States individual or business from paying, offering, or authorizing payment or offering of anything of value, directly or indirectly, to any foreign official, political party, or candidate for the purpose of influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the United States to comply with accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations. In many other countries, the healthcare providers who prescribe pharmaceuticals are employed by their government, and the purchasers of pharmaceuticals are government entities; therefore, our dealings with these prescribers and purchasers would be subject to regulation under the FCPA. Activities that violate the FCPA, even if they occur wholly outside the United States, can result in criminal and civil fines, imprisonment, disgorgement, oversight, and debarment from government contracts. Coverage and Reimbursement Market acceptance and sales of any drug products depend in part on coverage and the extent to which adequate reimbursement for drug products will be available from third-party payors, including government health administration authorities, managed care organizations and other private health insurers. Coverage and reimbursement for our product also depends on coverage and adequate reimbursement for the procedures using PB2452 as a ticagrelor reversal agent and PB1046 for the treatment of PAH. Obtaining coverage and adequate reimbursement for our products may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. Separate reimbursement for the product itself or the treatment or procedure in which our product is used may not be available. Even if the procedure using our product is covered, third-party payors may package the cost of the drug into the procedure payment and not separately reimburse the physician for the costs associated with our product. A decision by a third-party payor not to cover or separately reimburse for our products could reduce physician utilization of our products once approved. Additionally, in the United States, there is no uniform policy of coverage and reimbursement among third-party payors. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own coverage and reimbursement policies. However, decisions regarding the extent of coverage and amount of reimbursement to be provided is made on a payor-by-payor basis. One payor’s determination to provide coverage for a drug product does not assure that other payors will also provide coverage and adequate reimbursement. Third-party payors determine which medical procedures they will cover and establish reimbursement levels. Even if a third-party payor covers a particular procedure, the resulting reimbursement payment rates may not be adequate. Patients who are treated in-office for a medical condition generally rely on third-party payors to reimburse all or part of the costs associated with the procedure and may be unwilling to undergo such procedures in the absence of such coverage and adequate reimbursement. Reimbursement by a third-party payor may depend upon a number of factors, including the third-party payor’s determination that a procedure is safe, effective and medically necessary; appropriate for the specific patient; cost-effective; supported by peer-reviewed medical journals; included in clinical practice guidelines; and neither cosmetic, experimental, nor investigational. Further, from time to time, typically on an annual basis, payment rates are updated and revised by third-party payors. Such updates could impact the demand for our product candidates, to the extent that customers who are prescribed our product candidates, if approved, are not separately reimbursed for the cost of the product candidates. An example of payment updates is the Medicare program updates to physician payments, which is done on an annual basis. In the past, when the 31 application of the formula resulted in lower payment, Congress has passed interim legislation to prevent the reductions. The Medicare Access and CHIP Reauthorization Act of 2015, or MACRA, ended the use of the statutory formula and introduced a merit-based incentive bonus program for Medicare physicians, also referred to as the Quality Payment Program. This program provides clinicians with two ways to participate, including through the Advanced Alternative Payment Models, or APMs, and the Merit-based Incentive Payment System, or MIPS. In November 2019, CMS issued a final rule finalizing the changes to the Quality Payment Program. At this time, it is unclear how the introduction of the Quality Payment Program will impact overall physician reimbursement under the Medicare program. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. Impact of Healthcare Reform on our Business In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of drug product candidates, restrict or regulate post- approval activities and affect the profitable sale of drug product candidates. Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. In March 2010, the ACA was passed, which substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts the United States pharmaceutical industry. The ACA, among other things: (1) established an annual, nondeductible fee on any entity that manufactures or imports certain specified branded prescription drugs and biologic agents apportioned among these entities according to their market share in some government healthcare programs; (2) expanded the entities eligible for discounts under the 340B drug pricing program; (3) increased the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program, to 23.1% and 13% of the average manufacturer price for most branded and generic drugs, respectively and capped the total rebate amount for innovator drugs at 100% of the Average Manufacturer Price, or AMP; (4) expanded the eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals and by adding new mandatory eligibility categories for individuals with income at or below 133% of the federal poverty level, thereby potentially increasing manufacturers’ Medicaid rebate liability; (5) addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for certain drugs and biologics that are inhaled, infused, instilled, implanted or injected; (6) introduced a new Medicare Part D coverage gap discount program, in which manufacturers must now agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D; (7) created a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research; and (8) established a Center for Medicare and Medicaid Innovation at CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug. There remain judicial and Congressional challenges to certain aspects of the ACA, as well as efforts by the Trump administration to repeal or replace certain aspects of the ACA. While Congress has not passed comprehensive repeal legislation, bills affecting the implementation of certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs Act of 2017, or Tax Act, includes a provision repealing, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” In addition, the 2020 federal spending package permanently eliminates, effective January 1, 2020, the ACA-mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax and, effective January 1, 2021, also eliminates the health insurer tax. The Bipartisan Budget Act of 2018, or the BBA, among other things, amends the ACA, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole.” In December 2018, CMS published a new final rule permitting further collections and payments to and from certain ACA qualified health plans and health insurance issuers under the ACA risk adjustment program in response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. On December 14, 2018, a Texas United States District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the Tax Act. Additionally, on December 18, 2019, the United States Court of Appeals for the 5th Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining provisions of the ACA are invalid as well. On March 2, 2020, the United States Supreme Court granted two petitions to review the ruling of the 5th Circuit, and a decision is expected sometime in 2021. It is unclear how this decision, future decisions, subsequent appeals, and other efforts to repeal and replace the ACA will impact the ACA and our business. 32 Other legislative changes have been proposed and adopted since the ACA was enacted. These changes include aggregate reductions to Medicare payments to providers of 2% per fiscal year pursuant to the Budget Control Act of 2011, which began in 2013 and, due to subsequent legislative amendments to the statute, including the BBA, will remain in effect through 2029 unless additional Congressional action is taken. The American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to several providers, including hospitals and cancer treatment centers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These new laws may result in additional reductions in Medicare and other healthcare funding, which could have an adverse effect on customers for our product candidates, if approved, and, accordingly, our financial operations. Additionally, there has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. At the federal level, the Trump administration’s budget proposal for fiscal year 2020 contains further drug price control measures that could be enacted during the budget process or in other future legislation, including, for example, measures to permit Medicare Part D plans to negotiate the price of certain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid, and to eliminate cost sharing for generic drugs for low-income patients. Further, the Trump administration released a “Blueprint,” or plan, to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase drug manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products, and reduce the out of pocket costs of drug products paid by consumers. The Department of Health and Human Services has solicited feedback on some of these measures and, implemented others under its existing authority. For example, in May 2019, CMS issued a final rule to allow Medicare Advantage plans the option to use step therapy for Part B drugs beginning January 1, 2020. This final rule codified CMS's policy change that was effective January 1, 2019. Although these and other measures may require additional authorization to become effective, Congress and the Trump administration have indicated that they will continue to seek new legislative and/or administrative measures to control drug costs. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

The following information sets forth risk factors that could cause our actual results to differ materially from those contained in forward- looking statements we have made in this Annual Report on Form 10-K and those we may make from time 33 to time. You should carefully consider the risks described below, in addition to the other information contained in this Annual Report on Form 10-K and our other public filings. Our business, financial condition or results of operations could be harmed by any of these risks. The risks and uncertainties described below are not the only ones we face. Additional risks not presently known to us or other factors not perceived by us to present significant risks to our business at this time also may impair our business operations. Risks Related to Our Financial Position and Capital Needs We have incurred significant losses since our inception. We expect to incur losses over the next several years and may never achieve or maintain profitability. We are a clinical-stage biopharmaceutical company with a limited operating history. Since our inception, we have incurred significant net losses. Our net loss was $39.2 million for the year ended December 31, 2019. As of December 31, 2019, we had an accumulated deficit of $162.2 million. We expect to continue to incur significant expenses and operating losses for the foreseeable future. Since inception, we have financed our operations primarily with proceeds raised in our initial public offering, private placements of convertible debt and convertible preferred stock and borrowings under our term loan. In future periods we expect to receive up to $120.0 million from the SFJ Agreement. We have no products approved for commercialization and have never generated any revenue from product sales. We have devoted substantially all of our financial resources and efforts to the development of our clinical and preclinical product candidates and our proprietary half-life extending elastin-like polypeptide, or ELP, technology, including conducting preclinical studies and clinical trials. We expect to continue to incur significant expenses and operating losses over the next several years. We expect that it could be several years, if ever, before we have a commercialized product. Our net losses may fluctuate significantly from quarter to quarter and year to year. We anticipate that our expenses will increase substantially as we: • • • • • • • • • • • • continue our ongoing clinical trials of PB2452 and PB1046, as well as initiate and complete additional clinical trials, as needed; seek to expand our geographical reach through the SFJ Agreement and the corresponding clinical development support fees that we will incur; pursue regulatory approvals for PB2452 as a reversal agent for the antiplatelet drug ticagrelor and PB1046 for the treatment of PAH; develop PB6440 for treatment-resistant hypertension; seek to discover and develop additional clinical and preclinical product candidates; scale up our clinical and regulatory capabilities; establish a commercialization infrastructure and scale up external manufacturing and distribution capabilities to commercialize any product candidates for which we may obtain regulatory approval, including PB2452 and PB1046; adapt our regulatory compliance efforts to incorporate requirements applicable to marketed products; maintain, expand and protect our intellectual property portfolio; hire additional clinical, manufacturing and scientific personnel; add operational, financial and management information systems and personnel, including personnel to support our product development and planned future commercialization efforts; and incur additional legal, accounting and other expenses in operating as a public company. To become and remain profitable, we must succeed in developing and eventually commercializing product candidates that generate significant revenue. This will require us to be successful in a range of challenging activities, including completing preclinical testing and clinical trials of our product candidates, obtaining regulatory approval, and manufacturing, marketing and selling any product candidates for which we may obtain regulatory approval, as well as discovering and developing additional product candidates. We are only in the preliminary stages of most of these activities. We may never succeed in these activities and, even if we do, may never generate any revenue or revenue that is significant enough to achieve profitability. 34 Even if we achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would depress the value of our company and could impair our ability to raise capital, expand our business, maintain our development efforts, obtain product approvals, diversify our offerings or continue our operations. A decline in the value of our company could also cause you to lose all or part of your investment. We have a limited operating history and no history of commercializing products, which may make it difficult for an investor to evaluate the success of our business to date and to assess our future viability. We commenced operations in 2002, and our operations to date have been largely focused on raising capital and developing our clinical and preclinical product candidates and our proprietary ELP half-life extending technology, including undertaking preclinical studies and conducting clinical trials. To date, we have not yet demonstrated our ability to successfully complete pivotal clinical trials, obtain regulatory approvals, manufacture a product on a commercial scale, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful commercialization. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully developing and commercializing products. We may encounter unforeseen expenses, difficulties, complications, delays and other known or unknown factors in achieving our business objectives. We will need to develop commercial capabilities, and we may not be successful in doing so. We will need substantial additional funding to meet our financial obligations and to pursue our business objectives. If we are unable to raise capital when needed, we could be forced to curtail our planned operations and the pursuit of our growth strategy. Our operations have consumed substantial amounts of cash since inception. Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain regulatory approval and achieve product sales. We expect to continue to incur significant expenses and operating losses over the next several years as we complete our ongoing clinical trials of our product candidates, initiate future clinical trials of our product candidates, seek marketing approval for PB2452 as a ticagrelor reversal agent and PB1046 for the treatment of PAH, develop PB6440 for treatment- resistant hypertension and advance any of our other product candidates we may develop or otherwise acquire. In addition, our product candidates, if approved, may not achieve commercial success. Our revenue, if any, will be derived from sales of products that we do not expect to be commercially available for a number of years, if at all. If we obtain marketing approval for PB2452, PB1046, PB6440 or any other product candidates that we develop or otherwise acquire, we expect to incur significant commercialization expenses related to product sales, marketing, distribution and manufacturing. We also expect an increase in our expenses associated with creating additional infrastructure to support operations as a public company. As of December 31, 2019, we had cash and cash equivalents of $74.0 million. We believe that our existing cash and cash equivalents as of December 31, 2019, in addition to the $10.0 million received in March 2020 and the $80.0 million in anticipated proceeds that we will receive pursuant to the SFJ Agreement, will be sufficient to fund our operating expenses and capital requirements into the second half of 2021. This estimate is based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we expect. Changes may occur beyond our control that would cause us to consume our available capital before that time, including changes in and progress of our development activities, acquisitions of additional product candidates, and changes in regulation. Our future capital requirements will depend on many factors, including: • • • • • • • the progress and results of our ongoing and planned future clinical trials of PB2452 and PB1046 and our development of PB6440 and other preclinical programs; the timing and amount of any payments we receive under the SFJ Agreement; the scope, progress, results and costs of preclinical development, laboratory testing and clinical trials for any future product candidates we may decide to pursue; the extent to which we develop, in-license or acquire other product candidates and technologies; the number and development requirements of other product candidates that we may pursue; the costs, timing and outcome of regulatory review of our product candidates; the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our product candidates for which we receive marketing approval; 35 • • • • the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval; our ability to establish collaborations to commercialize PB1046 in the United States; our ability to establish collaborations to commercialize PB2452, PB1046, PB6440 or any of our other product candidates outside the United States; and the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims. We will require additional capital to commercialize PB2452, PB1046 and PB6440. If we receive regulatory approval for either of these product candidates, we expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution, depending on where we choose to commercialize. Additional funds may not be available on a timely basis, on favorable terms, or at all, and such funds, if raised, may not be sufficient to enable us to continue to implement our long-term business strategy. Further, our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to and volatility in the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-19 pandemic. If we are unable to raise sufficient additional capital, we could be forced to curtail our planned operations and the pursuit of our growth strategy. Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates. Until such time, if ever, as we can generate substantial revenue, we may finance our cash needs through a combination of equity offerings, government or private party grants, debt financings and license and collaboration agreements. Except with respect to the funding obligations pursuant to the SFJ Agreement, we do not currently have any other committed external source of funds. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. For example, under the SFJ Agreement, we granted SFJ a first-priority security interest in all of our assets related to PB2452, subject only to the lien of SVB for existing indebtedness to SVB. In connection with the grant of the security interest, we agreed to certain affirmative and negative covenants, including restrictions on our ability to pay dividends, incur additional debt or enter into licensing transactions with respect to intellectual property related to PB2452. Similarly, our loan and security agreement with Silicon Valley Bank, or SVB, and WestRiver Innovation Lending Fund VIII, L.P., or WestRiver, is secured by a security interest in substantially all of our current and future assets. We are also obligated to comply with various other customary covenants, including restrictions on our ability to encumber our intellectual property assets. The security interests granted to SFJ, SVB and WestRiver may preclude future debt financing or make the terms of such financings less favorable. If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish valuable rights to our technologies, future revenue streams or product candidates, grant licenses on terms that may not be favorable to us or commit to future payment streams. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves. If we receive regulatory approval for PB2452, or if the SFJ Agreement is terminated, we will be required to make substantial payments to SFJ pursuant to the SFJ Agreement. If we do not have sufficient funding or cash flow from our business to meet our payment obligations under the SFJ Agreement, SFJ could exercise its remedies as a holder of a first-priority security interest in our assets and our business could be materially harmed. On January 9, 2020, we entered into the SFJ Agreement, pursuant to which SFJ will provide up to $120 million to support the global development of PB2452. If we receive regulatory approval for PB2452 as a reversal agent for the antiplatelet drug ticagrelor, we will be required to make substantial payments to SFJ pursuant to the SFJ Agreement. Our ability to make these required payments depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flow from operations in the future sufficient to meet our obligations under the SFJ Agreement. If we are unable to generate such cash flow or to obtain additional funding through public or private equity offerings, debt financings, collaborations and licensing arrangements or other sources on acceptable terms or at all, we could default on our payment obligations to SFJ. We have granted SFJ a first-priority security interest in all 36 of our assets related to PB2452, subject only to the lien of SVB for existing indebtedness to SVB. If we are unable to meet our payment obligations to SFJ, SFJ may exercise its remedies as a holder of a first-priority security interest, which would result in a loss of our assets and our business would be materially harmed. In addition, in the event that (i) we fail to pay any amounts payable to SFJ under the SFJ Agreement within a specified time period, (ii) we are in default of our obligations (subject to certain exclusions) under the MedImmune License or (iii) either (a) we determine it is probable that we will be unable to meet our obligations as they become due within one year after the date that our financial statements for the then-current quarter are issued, or available to be issued or (b) a “going concern” footnote is included in any of our financial statements, and, in either case ((a) or (b)), we fail to remedy such going concern condition as specified in the agreement, SFJ may elect to have our business related to PB2452 transferred to SFJ. If our business related to PB2452 is transferred to SFJ, we will not share in any revenues from the commercialization of PB2452 until SFJ has received a 300% return on its investment in PB2452, after which we will be entitled to a mid-single-digit royalty on net sales of PB2452 in the United States and certain European countries, and after SFJ has received an aggregate 500% return on its investment in PB2452, we will be entitled to a mid-single-digit royalty on net sales of PB2452 in the rest of the world. In the event that the SFJ Agreement is terminated, we will be obligated to make substantial payments to SFJ. If following termination of the SFJ Agreement we continue to develop PB2452 and obtain BLA approval in the United States, the European Union, Japan or China, we will be obligated to pay applicable approval payments for any such jurisdiction to SFJ as if the SFJ Agreement had not been terminated, less any payments made upon termination, except in limited circumstances. Further, if our business related to SFJ is transferred to SFJ in the event that we breach certain provisions of the SFJ Agreement, we will not share in any revenues from the commercialization of PB2452 until SFJ has received an at least 300% return on its investment in PB2452. See “Business - License, Co-Development and Other Agreements - Co-Development Agreement for PB2452 with SFJ Pharmaceuticals.” Such payment obligations could have significant consequences for our stockholders and our business, results of operations and financial condition and could force us to delay or terminate development of PB2452 or other product candidates. Risks Related to the Development of Our Product Candidates We currently have only two clinical-stage product candidates, PB2452, a ticagrelor reversal agent, and PB1046 for the treatment of PAH. If we are unable to successfully develop, receive regulatory approval for and commercialize our product candidates for these or any other indications, or successfully develop any other product candidates, or experience significant delays in doing so, our business will be harmed. We currently have no products that are approved for commercial sale. We currently have only two clinical-stage product candidates, PB2452 and PB1046. To date, we have not yet conducted any pivotal clinical trials. We have not completed the development of any product candidates, and we may never be able to develop marketable products. We have invested substantially all of our efforts and financial resources in the development of our clinical and preclinical product candidates and our proprietary ELP technology. Our ability to generate revenue from our product candidates, which we do not expect will occur for several years, if ever, will depend heavily on the successful development, regulatory approval and eventual commercialization of our product candidates. The success of PB2452, PB1046, PB6440 or any other product candidates that we develop or otherwise may acquire will depend on several factors, including: • • • • • • • • • timely and successful completion of preclinical studies and clinical trials; sufficiency of our financial and other resources to complete the necessary preclinical studies and clinical trials; successful enrollment and completion of clinical trials; with respect to PB2452, the success of our collaboration with SFJ; successful development of, or making arrangements with third-party manufacturers for, our commercial manufacturing processes for any of our product candidates that receive regulatory approval; receipt of timely marketing approvals from applicable regulatory authorities; launching commercial sales of products, if approved; acceptance of our products, if approved, by patients, the medical community and third-party payors, for their approved indications; the prevalence and severity of adverse events experienced with PB2452, PB1046, PB6440 or any other product candidates; 37 • • • • • the availability, perceived advantages, cost, safety and efficacy of alternative therapies for any product candidate, and any indications for such product candidate, that we develop, specifically, alternative antiplatelet therapies to ticagrelor, including therapies that may be developed with a reversal agent, alternative reversal agents for ticagrelor or alternative treatments for PAH or treatment-resistant hypertension; our ability to produce PB2452, PB1046, PB6440 or any other product candidates we develop on a commercial scale; obtaining and maintaining patent, trademark and trade secret protection and regulatory exclusivity for our product candidates and otherwise protecting our rights in our intellectual property portfolio; maintaining compliance with regulatory requirements, including current good manufacturing practices, or cGMPs, and complying effectively with other procedures; and maintaining a continued acceptable safety, tolerability and efficacy profile of the products following approval. If we are not successful with respect to one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize the product candidates we develop, which would materially harm our business. If we do not receive marketing approvals for PB2452, PB1046, PB6440 or any other product candidate we develop, we may not be able to continue our operations. The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time consuming and inherently unpredictable. If we are not able to obtain required regulatory approval for our product candidates, our business will be substantially harmed. The time required to obtain approval or other marketing authorizations by the FDA and comparable foreign authorities is unpredictable, and it typically takes many years following the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, regulations, and the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions. PB2452 and PB1046 are currently our only clinical-stage product candidates. We have not obtained regulatory approval for any product candidate, and it is possible that we may never obtain regulatory approval for PB2452, PB1046, PB6440 or any product candidates we may seek to develop in the future. Neither we nor any current or future collaborator is permitted to market any drug product candidates in the United States until we receive regulatory approval of a BLA, or a new drug application, or NDA, from the FDA. To date, we have only had limited discussions with the EMA and other comparable foreign authorities regarding regulatory approval for PB2452, PB1046 or any other product candidate outside of the United States. Prior to obtaining approval to commercialize any drug product candidate in the United States or abroad, we must demonstrate with substantial evidence from well-controlled clinical trials, and to the satisfaction of the FDA or foreign regulatory agencies, that such product candidates are safe, pure and effective for their intended uses. Results from preclinical studies and clinical trials can be interpreted in different ways. Even if we believe the preclinical or clinical data for our product candidates are promising, such data may not be sufficient to support approval by the FDA and other regulatory authorities. The FDA may also require us to conduct additional preclinical studies or clinical trials for our product candidates either prior to or after approval, or it may object to elements of our clinical development programs. Of the large number of products in development, only a small percentage successfully complete the FDA or foreign regulatory approval processes and are commercialized. The lengthy approval and marketing authorization process as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval and marketing authorization to market our product candidates, which would significantly harm our business, financial condition, results of operations and prospects. We have invested a significant portion of our time and financial resources in the development of our clinical and preclinical product candidates, including PB2452, PB1046 and PB6440. Our business is dependent on our ability to successfully complete preclinical and clinical development of, obtain regulatory approval for, and, if approved, successfully commercialize PB2452, PB1046, PB6440 and any future product candidates in a timely manner. Even if we eventually complete clinical testing and receive approval of a BLA, NDA or foreign marketing application for PB2452, PB1046, PB6440 or any future product candidates, the FDA or the applicable foreign regulatory agency may grant approval or other marketing authorization contingent on the performance of costly additional clinical trials, 38 including post-marketing clinical trials. The FDA or the applicable foreign regulatory agency also may approve or authorize for marketing a product candidate for a more limited indication or patient population than we originally request, and the FDA or applicable foreign regulatory agency may not approve or authorize the labeling that we believe is necessary or desirable for the successful commercialization of a product candidate. Any delay in obtaining, or inability to obtain, applicable regulatory approval or other marketing authorization would delay or prevent commercialization of that product candidate and would materially adversely impact our business and prospects. In addition, the FDA and other regulatory authorities may change their policies, issue additional regulations or revise existing regulations, or take other actions, which may prevent or delay approval of our future products under development on a timely basis. Such policy or regulatory changes could impose additional requirements upon us that could delay our ability to obtain approvals, increase the costs of compliance or restrict our ability to maintain any marketing authorizations we may have obtained. Based on feedback from the FDA, we intend to seek regulatory approval of PB2452 in the United States through an accelerated approval process. If we are not successful with this process, the development and commercialization of PB2452 could be delayed, abandoned or significantly more costly. The FDA’s accelerated approval regulations allow drugs that are being developed to treat an unmet medical need to be approved substantially based on evidence of an effect on a surrogate biomarker endpoint that is considered reasonably likely to predict clinical benefit, rather than a clinical endpoint such as survival or irreversible morbidity. Based on feedback from the FDA, our strategy is to use an accelerated approval pathway that may require that our Phase 3 clinical trial of PB2452 be ongoing at the time of BLA approval. To support our BLA submission for accelerated approval, the FDA recommended an interim analysis of biomarker data from an initial subset of 100 patients, with approximately 50 patients with uncontrolled major or life-threatening bleeding and approximately 50 patients requiring urgent surgery or an invasive procedure, in our Phase 3 trial, together with safety data from our Phase 2 clinical trials. After we submit our BLA with data from the first 100 patients, we intend to complete the Phase 3 trial and establish a post- approval registry in accordance with FDA requirements. If the FDA requires the completion of the Phase 3 trial prior to the submission of a BLA, the development and commercialization timeline of PB2452 will be delayed. Further, the FDA may determine that the trials conducted by us were insufficient to support approval for all or some of the proposed indications, require us to conduct extensive post-approval studies or require us to make modifications to our ongoing Phase 3 clinical trial after approval and marketing. Clinical product development involves a lengthy and expensive process, with an uncertain outcome. We may incur additional costs and experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates. In order to obtain FDA approval to market a new biological or drug product we must demonstrate proof of safety, purity and efficacy in humans. The risk of failure for product candidates is high. It is impossible to predict when or if any of our product candidates will prove effective or safe in humans or will receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate, we must complete preclinical development and then conduct extensive clinical trials to demonstrate the safety, purity, potency, and efficacy of our product candidates in humans. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is inherently uncertain as to outcome. A failure of one or more clinical trials can occur at any stage of testing or at any time during the trial process. The outcome of preclinical testing and early clinical trials may not be predictive of the results of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their products. We have not completed all clinical trials required for the approval of any of our product candidates. We cannot assure you that any clinical trial that we are conducting, or may conduct in the future, will demonstrate consistent or adequate efficacy and safety to obtain regulatory approval to market our product candidates. We may incur additional costs and experience delays in ongoing clinical trials for our product candidates, and we do not know whether future clinical trials, if any, will begin on time, need to be redesigned, enroll an adequate number of patients on time or be completed on schedule, if at all. We may experience numerous unforeseen events during or as a result of clinical trials that could delay or prevent our ability to receive marketing approval or commercialize our product candidates, including: • regulators or institutional review boards may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site; 39 • • • • • • • • we may experience delays in reaching, or fail to reach, agreement on acceptable clinical trial contracts or clinical trial protocols with prospective trial sites or prospective contract research organizations, or CROs, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites; clinical trials of our product candidates may produce negative or inconclusive results, including failure to demonstrate statistical significance, and we may decide, or regulators may require us, to conduct additional clinical trials or abandon product development programs; the number of patients required for clinical trials of our product candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipate or participants may drop out of these clinical trials or fail to return for post- treatment follow-up at a higher rate than we anticipate; our product candidates may have undesirable side effects or other unexpected characteristics, causing us or our investigators, regulators or institutional review boards to suspend or terminate the trials; our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all; regulators or institutional review boards may require that we or our investigators suspend or terminate clinical development for various reasons, including noncompliance with regulatory requirements or a finding that the participants are being exposed to unacceptable health risks; the cost of clinical trials of our product candidates may be greater than we anticipate; and the supply or quality of our product candidates or other materials necessary to conduct clinical trials of our product candidates may be insufficient or inadequate. If we experience delays in the completion of, or termination of, any clinical trial of our product candidates, the commercial prospects of our product candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenues. If we are required to conduct additional clinical trials or other testing of our product candidates beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our product candidates or other testing, if the results of these trials or tests are not favorable or if there are safety concerns, we may: • • • • • • be delayed in obtaining marketing approval for our product candidates; not obtain marketing approval at all; obtain approval for indications or patient populations that are not as broad as intended or desired; obtain approval with labeling that includes significant use or distribution restrictions or safety warnings; be subject to additional post-marketing testing requirements; or have the product removed from the market after obtaining marketing approval. Success in preclinical studies or earlier clinical trials may not be indicative of results in future clinical trials. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will generate the same results or otherwise provide adequate data to demonstrate the efficacy and safety of a product candidate. Preclinical tests and Phase 1 and Phase 2 clinical trials are primarily designed to test safety, to study pharmacokinetics and pharmacodynamics and to understand the side effects of product candidates at various doses and schedules. Success in preclinical or animal studies and early clinical trials does not ensure that later large-scale efficacy trials will be successful nor does it predict final results. Our product candidates may fail to show the desired safety and efficacy in clinical development despite positive results in preclinical studies or having successfully advanced through initial clinical trials. Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials even after achieving promising results in preclinical testing and earlier-stage clinical trials. Data obtained from preclinical and clinical activities are subject to varying interpretations, which may delay, limit or prevent regulatory approval. In addition, we may experience regulatory delays or rejections as a result of many factors, including changes in 40 regulatory policy during the period of our product candidate development. Any such delays could negatively impact our business, financial condition, results of operations and prospects. Interim “top-line” and preliminary results from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data. From time to time, we may publish interim top-line or preliminary results from our clinical trials. Interim results from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Preliminary or top-line results also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, interim and preliminary data should be viewed with caution until the final data are available. Differences between preliminary or interim data and final data could significantly harm our business prospects and may cause the trading price of our common stock to fluctuate significantly. Our clinical trials may fail to demonstrate the safety and efficacy of our product candidates, or serious adverse or unacceptable side effects may be identified during the development of our product candidates, which could prevent or delay regulatory approval and commercialization, increase our costs or necessitate the abandonment or limitation of the development of some of our product candidates. Before obtaining regulatory approvals for the commercial sale of our product candidates, we must demonstrate through lengthy, complex and expensive preclinical testing and clinical trials that our product candidates are safe, pure and effective for use in each target indication, and failures can occur at any stage of testing. Clinical trials often fail to demonstrate safety or efficacy of the product candidate studied for the target indication. If our product candidates are associated with side effects in clinical trials or have characteristics that are unexpected, we may need to abandon their development or limit development to more narrow uses in which the side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. The FDA or an institutional review board may also require that we suspend, discontinue, or limit our clinical trials based on safety information, or that we conduct additional animal or human studies regarding the safety and efficacy of our product candidates which we have not planned or anticipated. Such findings could further result in regulatory authorities failing to provide marketing authorization for our product candidates or limiting the scope of the approved indication, if approved. Many product candidates that initially showed promise in early stage testing have later been found to cause side effects that prevented further development of the product candidate. Additionally, if one or more of our product candidates receives marketing approval, and we or others identify undesirable side effects caused by such products, a number of potentially significant negative consequences could result, including: • • • • • • regulatory authorities may withdraw approvals of such product; regulatory authorities may require additional warnings on the labels; we may be required to create a medication guide outlining the risks of such side effects for distribution to patients; we could be sued and held liable for harm caused to patients; we may not be able to achieve or maintain third-party payor coverage and adequate reimbursement; and our reputation and physician or patient acceptance of our products may suffer. There can be no assurance that we will resolve any issues related to any product-related adverse events to the satisfaction of the FDA or foreign regulatory agency in a timely manner or at all. Moreover, any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and could significantly harm our business, results of operations and prospects. As an organization, we have never conducted pivotal clinical trials, and we may be unable to do so for any product candidates we may develop. We will need to successfully complete pivotal clinical trials in order to obtain the approval of the FDA, EMA or other regulatory agencies to market PB2452, PB1046, PB6440 or any future product candidate. Carrying out pivotal clinical 41 trials is a complicated process. As an organization, we have not previously conducted any later stage or pivotal clinical trials. In order to do so, we will need to expand our clinical development and regulatory capabilities, and we may be unable to recruit and train qualified personnel. We also expect to continue to rely on third parties to conduct our pivotal clinical trials. See “— Risks Related to our Dependence on Third Parties —We will rely on third parties to conduct our future clinical trials for product candidates, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such trials.” In particular, pursuant to the SFJ Agreement, SFJ will have primary responsibility for clinical development and regulatory activities for PB2452 in China and Japan and will provide clinical trials operational support in the European Union. Consequently, we may be unable to successfully and efficiently execute and complete necessary clinical trials in a way that leads to BLA or NDA submission and approval of PB2452, PB1046, PB6440 or future product candidates. We may require more time and incur greater costs than our competitors and may not succeed in obtaining regulatory approvals of product candidates that we develop. Failure to commence or complete, or delays in, our planned clinical trials, could prevent us from or delay us in commercializing our product candidates. If we experience delays or difficulties in the enrollment and/or maintenance of patients in clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented. Successful and timely completion of clinical trials will require that we enroll a sufficient number of patients. Patient enrollment, a significant factor in the timing of clinical trials, is affected by many factors, including the size and nature of the patient population. Trials may be subject to delays as a result of patient enrollment taking longer than anticipated or patient withdrawal. We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA or foreign regulatory authorities. We cannot predict how successful we will be at enrolling subjects in future clinical trials. Subject enrollment is affected by other factors including: • • • • • • • • • • the eligibility criteria for the trial in question; the size of the patient population and process for identifying patients; the perceived risks and benefits of the product candidate in the trial; the availability of competing commercially available therapies and other competing drug candidates’ clinical trials; the willingness of patients to be enrolled in our clinical trials; the efforts to facilitate timely enrollment in clinical trials; potential disruptions caused by the COVID-19 pandemic, including difficulties in initiating clinical sites, enrolling participants, diversion of healthcare resources away from clinical trials, travel or quarantine policies that may be implemented, and other factors; the patient referral practices of physicians; the ability to monitor patients adequately during and after treatment; and the proximity and availability of clinical trial sites for prospective patients. Our inability to enroll a sufficient number of patients for clinical trials would result in significant delays and could require us to abandon one or more clinical trials altogether. Enrollment delays in these clinical trials may result in increased development costs for our product candidates, which would cause the value of our company to decline and limit our ability to obtain additional financing. Furthermore, we rely on and expect to continue to rely on CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials and we will have limited influence over their performance. Furthermore, even if we are able to enroll a sufficient number of patients for our clinical trials, we may have difficulty maintaining enrollment of such patients in our clinical trials. Changes in methods of product candidate manufacturing or formulation may result in additional costs or delay. As product candidates proceed through preclinical studies to late-stage clinical trials towards potential approval and commercialization, it is common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort to optimize processes and product characteristics. Such changes carry the risk that they will not achieve these intended objectives. Any of these changes could cause our product candidates to perform differently and affect the results of planned clinical trials or other future clinical trials conducted with the materials manufactured using altered processes. Such changes may also require additional testing, FDA notification or FDA approval. 42 This could delay completion of clinical trials, require the conduct of bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates and jeopardize our ability to commence sales and generate revenue. Our clinical development of PB2452 depends on the continued use of ticagrelor as an antiplatelet therapy. We are developing PB2452 as a ticagrelor reversal agent for the treatment of patients on ticagrelor with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure. If previously unknown safety risks related to ticagrelor are discovered that would affect its use as an antiplatelet therapy, or if market acceptance of ticagrelor significantly changes, we may pause or stop development of PB2452, which would significantly and adversely affect our business prospects. ELP is a novel technology, which makes it difficult to predict the time, risks and cost of development and of subsequently obtaining regulatory approval of our ELP product candidates. PB1046 and certain other preclinical product candidates are based on our proprietary ELP technology. Some of our future success depends on the successful development of this technology and products based on it. To our knowledge, no regulatory authority has granted approval to any person or entity, including us, to market and commercialize therapeutics using our novel ELP technology. We may never receive approval to market and commercialize any product candidate that utilizes ELP. If we uncover any previously unknown risks related to our ELP technology, or if we experience unanticipated problems or delays in developing our ELP product candidates, we may be unable to complete our clinical trials and preclinical studies, meet the obligations of our license agreements or commercialize our product candidates on a timely or profitable basis. If serious adverse events or unacceptable side effects are observed in clinical trials or preclinical studies of a product candidate based on our ELP technology, our ability to develop other product candidates based on our ELP technology would be adversely affected. We may be unable to obtain or maintain orphan drug designations or exclusivity for PB1046 or other product candidates, which could limit the potential profitability of such product candidates. Regulatory authorities in some jurisdictions, including the United States, designate drugs intended for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, which is a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States for which there is no reasonable expectation that the cost of developing and making available in the United States a drug or biologic for this type of disease or condition will be recovered from sales in the United States for that drug or biologic. Generally, a product that has orphan drug designation and subsequently receives the first FDA approval for the disease for which it has such designation is entitled to orphan drug exclusive approval (or exclusivity), which means that the FDA may not approve any other applications, including a full BLA, to market the same drug or biologic for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity. A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. The FDA has granted two orphan drug designations for PB1046: one for the treatment of PAH and a second for cardiomyopathy associated with DMD. We may seek orphan drug designation for future indications for PB1046 or for other product candidates. Even if we were to obtain orphan drug designation for a product candidate, we may not obtain orphan exclusivity and that exclusivity may not effectively protect the drug from the competition of different drugs for the same condition, which could be approved during the exclusivity period. Additionally, after an orphan drug is approved, the FDA could subsequently approve another application for the same drug for the same indication if the FDA concludes that the later drug is shown to be safer or more effective or makes a major contribution to patient care. Orphan drug exclusive marketing rights in the United States also may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. The failure to obtain an orphan drug designation for any product candidates we may develop, the inability to maintain that designation for the duration of the applicable period, or the inability to obtain or maintain orphan drug exclusivity could reduce our ability to make sufficient sales of the applicable product candidate to balance our expenses incurred to develop it, which would have a negative impact on our operational results and financial condition. 43 Breakthrough Therapy designation by the FDA and PRIME designation by the EMA for PB2452, or any other product candidate, may not lead to a faster development or regulatory review or approval process, and it does not increase the likelihood that the product candidate will receive marketing approval. We have received a Breakthrough Therapy designation for PB2452 for the reversal of ticagrelor's antiplatelet activity and may, in the future, apply for Breakthrough Therapy designation for other product candidates. A Breakthrough Therapy is defined as a product candidate that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the product candidate may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. For product candidates that have been designated as Breakthrough Therapies, interaction and communication between the FDA and the sponsor of the trial can help to identify the most efficient path for clinical development while minimizing the number of patients placed in ineffective control regimens. Product candidates designated as breakthrough therapies by the FDA are also eligible for priority review if supported by clinical data at the time of the submission of the BLA. Designation as a Breakthrough Therapy is within the discretion of the FDA. Accordingly, even if we believe that one of our product candidates meets the criteria for designation as a Breakthrough Therapy, the FDA may disagree and instead determine not to make such designation. In any event, the receipt of a Breakthrough Therapy designation for a product candidate may not result in a faster development process, review or approval compared to product candidates considered for approval under conventional FDA procedures and it would not assure ultimate approval by the FDA. In addition, even if one or more of our product candidates qualify as Breakthrough Therapies, the FDA may later decide that the product candidate no longer meets the conditions for qualification or it may decide that the time period for FDA review or approval will not be shortened. Access to the PRIME initiative is granted by the EMA to support the development and accelerate the review of new therapies to treat patients with unmet medical need. The receipt of this access for a product candidate may not result in a faster development process, review or approval compared to products considered for approval under conventional EMA procedures and, in any event, does not assure ultimate approval by the EMA. In addition, even though PB2452 has been granted access to PRIME, the EMA may later decide that it no longer meets the conditions for such access. We may not be successful in our efforts to increase our pipeline of product candidates, including by pursuing additional indications for our current product candidates or in-licensing or acquiring additional product candidates for other diseases. A key element of our strategy is to build and expand our pipeline of product candidates, including by developing PB1046 for the treatment of other orphan conditions, and PB6440 for treatment-resistant hypertension and identifying other product candidates using our ELP technology. In addition, we may in-license or acquire additional product candidates for other diseases. We may not be able to identify or develop product candidates that are safe, tolerable and effective. Even if we are successful in continuing to build our pipeline, the potential product candidates that we identify, in-license or acquire may not be suitable for clinical development, including as a result of being shown to have harmful side effects or other characteristics that indicate that they are unlikely to be products that will receive marketing approval and achieve market acceptance. We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success. Because we have limited financial and management resources, we focus on development programs and product candidates that we identify for specific indications. As such, we are currently primarily focused on the development of PB2452 as a ticagrelor reversal agent, PB1046 for the treatment of PAH and PB6440 for treatment-resistant hypertension. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications for PB1046 that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future development programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate. The ongoing COVID-19 pandemic could adversely impact our business, including our clinical trials. In December 2019, a novel strain of coronavirus, SARS-CoV-2, was reported to have surfaced in Wuhan, China and to cause a severe respiratory illness now known as COVID-19. Since then, COVID-19 has spread to multiple countries, 44 including the United States and several European countries, including countries in which we have ongoing and planned clinical trials. In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic, and the U.S. government imposed travel restrictions on travel between the United States, Europe, Canada and other countries. Further, the President of the United States declared the COVID-19 pandemic a national emergency, invoking powers under the Stafford Act, the legislation that directs federal emergency disaster response. We may experience disruptions due to the COVID-19 pandemic that could severely impact our business and clinical trials, including: • • • • • • delays, difficulties or a suspension in enrolling patients in our ongoing and planned clinical trials; delays, difficulties or a suspension in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff; interruptions in our ability to manufacture and deliver drug supply for trials; diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials; interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others; and limitations in employee resources that would otherwise be focused on the conduct of our clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people. For our clinical trials that are planned to be conducted at sites in countries that are experiencing heightened impact from COVID-19, in addition to the risks listed above, we may also experience the following adverse impacts: • • • • • • delays in receiving approval from local regulatory authorities to initiate our planned clinical trials; delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials; interruption in global shipping that may affect the transport of clinical trial materials, such as investigational drug product used in our clinical trials; changes in local regulations as part of a response to the COVID-19 outbreak which may require us to change the ways in which our clinical trials are conducted, which may result in unexpected costs, or to discontinue the clinical trials altogether; delays in necessary interactions with local regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government employees; and refusal of the FDA to accept data from clinical trials in these affected geographies. As we advance our clinical programs for PB2452 and PB1046 with site activations and patient enrollment, we remain in close contact with our CROs, clinical sites and suppliers to attempt to assess the impacts that COVID-19 may have on our clinical trials and current timelines and to consider whether we can implement appropriate mitigating measures to help to lessen such impacts. At this time, however, we cannot currently fully forecast the scope of impacts that COVID-19 may have on our ability to initiate trial sites, enroll and assess patients, supply study drug and report trial results. To date, we have temporarily paused enrollment of new patients in the PB1046 Phase 2b clinical trial as a precaution to minimize potential exposure of this patient population at high risk of serious illness from COVID-19. Although we have been targeting to report results from this trial in the fourth quarter of 2020, we believe that the COVID-19 outbreak will temporarily prevent us from being able to initiate new trial sites and enroll new patients, likely delaying our ability to report the results of this trial into 2021. The global COVID-19 pandemic continues to rapidly evolve. The extent to which COVID-19 may impact our business and clinical trials will depend on future developments that are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease. The United Kingdom’s withdrawal from the European Union may have a negative effect on global economic conditions, financial markets and our business. 45 Following the result of a referendum in 2016, the United Kingdom, or UK, left the European Union, or EU, on January 31, 2020, commonly referred to as Brexit. Pursuant to the formal withdrawal arrangements agreed to by the UK and the EU, the UK will be subject to a transition period until December 31, 2020, or the Transition Period, during which EU rules will continue to apply. Negotiations between the UK and the EU are expected to continue in relation to the customs and trading relationship between the UK and the EU following the expiry of the Transition Period. Since a significant proportion of the regulatory framework in the UK applicable to our business and our product candidates is derived from EU directives and regulations, Brexit, following the Transition Period, could materially impact the regulatory regime with respect to the development, manufacture, importation, approval and commercialization of our product candidates in the UK or the EU. For example, as a result of the uncertainty surrounding Brexit, the EMA relocated to Amsterdam from London. Following the Transition Period, the UK will no longer be covered by the centralized procedures for obtaining EU-wide marketing and manufacturing authorizations from the EMA and, unless a specific agreement is entered into, a separate process for authorization of drug products will be required in the UK, the potential process for which is currently unclear. Any delay in obtaining, or an inability to obtain, any marketing approvals, as a result of Brexit or otherwise, would prevent us from commercializing our product candidates in the UK or the EU and limit our ability to generate revenue and achieve and sustain profitability. In addition, we may be required to pay taxes or duties or be subjected to other hurdles in connection with the importation of our product candidates into the EU, or we may incur expenses in establishing a manufacturing facility in the EU in order to circumvent such hurdles. If any of these outcomes occur, we may be forced to restrict or delay efforts to seek regulatory approval in the UK or the EU for our product candidates, or incur significant additional expenses to operate our business, which could significantly and materially harm or delay our ability to generate revenues or achieve profitability of our business. Any further changes in international trade, tariff and import/export regulations as a result of Brexit or otherwise may impose unexpected duty costs or other non-tariff barriers on us. These developments, or the perception that any of them could occur, may significantly reduce global trade and, in particular, trade between the impacted nations and the UK. It is also possible that Brexit may negatively affect our ability to attract and retain employees, particularly those from the EU. Risks Related to the Commercialization of Our Product Candidates Market acceptance of PB2452, if approved, will depend heavily on the continued market acceptance and use of ticagrelor. The commercial success of PB2452 as a ticagrelor reversal agent, if approved, is dependent on the continued market acceptance and use of ticagrelor as an antiplatelet therapy. Ticagrelor competes against other commercially available antiplatelet therapies, including other P2Y12 receptor antagonists, many of which are available as generic drugs and therefore significantly less expensive than ticagrelor. New antiplatelet therapies may also be developed in the future, including other P2Y12 receptor antagonists and other antiplatelet therapies, which could also have reversal agents, that could displace ticagrelor as the American College of Cardiology, American Heart Association and European Society of Cardiology’s preferred antiplatelet agent for acute coronary syndrome or otherwise reduce ticagrelor’s market position. Any such changes in the market acceptance and use of ticagrelor would significantly harm our business, results of operations and prospects for PB2452. Even if any of our product candidates receive marketing approval, they may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success. If any of our product candidates receive marketing approval, they may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. If our product candidates do not achieve an adequate level of acceptance, we may not generate significant revenue and we may not become profitable. The degree of market acceptance of our product candidates, if approved for commercial sale, will depend on a number of factors, including: • • • • • • • the efficacy, safety and potential advantages compared to alternative treatments; our ability to offer our products for sale at competitive prices; the convenience and ease of administration compared to alternative treatments; product labeling or product insert requirements of the FDA or foreign regulatory authorities, including any limitations or warnings contained in a product’s approved labeling, including any black box warning; the willingness of the target patient population to try new treatments and of physicians to prescribe these treatments; our ability to hire and retain a sales force in the United States; the strength of marketing and distribution support; 46 • • • the availability of third-party coverage and adequate reimbursement for PB2452, PB1046, PB6440 and any other product candidates, once approved; the prevalence and severity of any side effects; and any restrictions on the use of our products together with other medications. If we are unable to establish sales, marketing and distribution capabilities for PB2452, PB1046, PB6440 or any other product candidate that may receive regulatory approval, we may not be successful in commercializing those product candidates if and when they are approved. We do not have sales or marketing infrastructure. To achieve commercial success for PB2452, PB1046, PB6440 or any other product candidate for which we may obtain marketing approval, we will need to establish a sales and marketing organization. In the future, we expect to build a focused sales and marketing infrastructure to market some of our product candidates in the United States, if and when they are approved. There are risks involved with establishing our own sales, marketing and distribution capabilities. For example, recruiting and training a sales force is expensive and time consuming and could delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing capabilities is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel. Factors that may inhibit our efforts to market our products on our own include: • • • • our inability to recruit, train and retain adequate numbers of effective sales and marketing personnel; the inability of sales personnel to obtain access to physicians in order to educate physicians about our product candidates, once approved; the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines; and unforeseen costs and expenses associated with creating an independent sales and marketing organization. If we are unable to establish our own sales, marketing and distribution capabilities and are forced to enter into arrangements with, and rely on, third parties to perform these services, our revenue and our profitability, if any, are likely to be lower than if we had developed such capabilities ourselves. In addition, we may not be successful in entering into arrangements with third parties to sell, market and distribute our product candidates or may be unable to do so on terms that are favorable to us. We likely will have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products effectively. If we do not establish sales, marketing and distribution capabilities successfully, either on our own or in collaboration with third parties, we will not be successful in commercializing our product candidates. We face substantial competition, which may result in a smaller than expected commercial opportunity and/or others discovering, developing or commercializing products before or more successfully than we do. The life sciences industry is highly competitive. We face competition with respect to our current product candidates, and will face competition with respect to any product candidates that we may seek to develop or commercialize in the future, from many different sources, including major pharmaceutical and specialty pharmaceutical companies, compounding facilities, academic institutions and governmental agencies and public and private research institutions. There are currently no other known reversal agents approved or in clinical development for ticagrelor or any other antiplatelet drugs. In the European Union, an extracorporeal whole blood purification adsorber device is available that may be useful for non-specific removal of ticagrelor during some cardiac procedures when used in conjunction with cardiopulmonary bypass. Upon approval, PB2452 would be the only therapeutic agent available for specific reversal of ticagrelor. There can be no assurance that competitors will not seek to develop a competing product. Moreover, the success of PB2452, if approved, will be dependent on the continued success of ticagrelor. See “—Market acceptance of PB2452, if approved, will depend heavily on the continued market acceptance and use of ticagrelor.” We are aware of several other products and product candidates as potential treatments for PAH that would compete with PB1046. Although we anticipate that PB1046 may be used as a complement to patients’ existing therapies, we expect to compete with existing treatments for PAH patients with Class II-IV symptoms that target the endothelin, nitric oxide and prostacyclin pathways, as well as any generic equivalents that may be developed. In addition to currently approved drugs 47 within these classes, we are also aware of a number of PAH therapies in clinical development with which PB1046 would compete if approved. We are aware of several other products and product candidates as potential treatments for treatment-resistant hypertension that could compete with PB6440. Although we anticipate that PB6440 may be used as a complement to patients’ existing antihypertensive therapies, we expect to compete with existing generic treatments for hypertension that target the mineralocorticoid receptor. In addition to the currently approved mineralocorticoid receptor antagonists, eplerenone and spironolactone, we are also aware of a number of therapies in clinical development for the treatment of resistant hypertension with which PB6440 would compete if approved. In addition, our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer or more effective, have fewer or less severe side effects, are more convenient or are less expensive than PB2452, PB1046, PB6440 or any other product that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for our product, which could result in our competitors establishing a strong market position before we are able to enter the market. Many of the companies against which we are competing, or against which we may compete in the future, have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or that may be necessary for, our programs. The success of PB2452 as a ticagrelor reversal agent, PB1046 for the treatment of PAH, PB6440 for treatment-resistant hypertension or any future product candidate, will depend significantly on coverage and adequate reimbursement or the willingness of patients to pay for these procedures. We believe our success depends on obtaining and maintaining coverage and adequate reimbursement for PB2452 as a ticagrelor reversal agent, PB1046 for the treatment of PAH, PB6440 for treatment-resistant hypertension and/or procedures utilizing PB2452, PB1046, PB6440 or any other product candidate, and the extent to which patients will be willing to pay out-of-pocket for such products and procedures, in the absence of reimbursement for all or part of the cost. Obtaining coverage and adequate reimbursement for our products may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. Separate reimbursement for the product itself or the treatment or procedure in which our product is used may not be available. Even if the procedure using our product is covered, third-party payors, such as Medicare, Medicaid, managed care organizations, and private health insurers, may package the cost of the drug into the procedure payment and not separately reimburse the physician for the costs associated with our product. A decision by a third-party payor not to cover or separately reimburse for our products could reduce physician utilization of our products once approved. Additionally, in the United States, there is no uniform policy of coverage and reimbursement among third-party payors. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own coverage and reimbursement policies. However, decisions regarding the extent of coverage and amount of reimbursement to be provided are made on a payor-by-payor basis. One payor’s determination to provide coverage for a drug product does not assure that other payors will also provide coverage, and adequate reimbursement. Third-party payors determine which products and procedures they will cover and establish reimbursement levels. Even if a third-party payor covers a particular product or procedure, the resulting reimbursement payment rates may not be adequate. Patients who are treated in-office for a medical condition generally rely on third-party payors to reimburse all or part of the costs associated with the procedure, including costs associated with products used during the procedure, and may be unwilling to undergo such procedures in the absence of such coverage and adequate reimbursement. Physicians may be unlikely to offer procedures for such treatment if they are not covered by insurance and may be unlikely to purchase and use our product candidates, if approved, for our stated indications unless coverage is provided and reimbursement is adequate. Reimbursement by a third-party payor may depend upon a number of factors, including the third-party payor’s determination that a procedure is safe, effective and medically necessary; appropriate for the specific patient; cost-effective; supported by peer-reviewed medical journals; included in clinical practice guidelines; and neither cosmetic, experimental, nor investigational. 48 Further, from time to time, typically on an annual basis, payment rates are updated and revised by third-party payors. An example of payment rate updates occurs in the Medicare program updates to physician payments, which is done on an annual basis. In the past, when the application of the formula resulted in lower payment, Congress has passed interim legislation to prevent the reductions. The Medicare Access and CHIP Reauthorization Act of 2015, or MACRA, ended the use of the statutory formula and introduced a merit-based incentive bonus program for Medicare physicians, also referred to as the Quality Payment Program. This program provides clinicians with two ways to participate, including through the Advanced Alternative Payment Models and the Merit-based Incentive Payment System. In November 2019, CMS issued a rule finalizing the changes to the Quality Payment Program. At this time, it is unclear how the introduction of the Quality Payment Program will impact overall physician reimbursement under the Medicare program. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. Any resulting decrease in payment under the merit-based reimbursement system may adversely affect our revenue and results of operations. In addition, the Medicare physician fee schedule has been adapted by some private payors into their plan-specific physician payment schedule. We cannot predict how pending and future healthcare legislation will impact our business, and any changes in coverage and reimbursement that further restricts coverage of our product candidates or lowers reimbursement for procedures using our products could harm our business. Foreign governments also have their own healthcare reimbursement systems, which vary significantly by country and region, and we cannot be sure that coverage and adequate reimbursement will be made available with respect to the treatments in which our products are used under any foreign reimbursement system. There can be no assurance that PB2452, PB1046, PB6440 or any other product candidate, if approved for sale in the United States or in other countries, will be considered medically reasonable and necessary, that it will be considered cost-effective by third-party payors, that coverage or an adequate level of reimbursement will be available or that reimbursement policies and practices in the United States and in foreign countries where our products are sold will not adversely affect our ability to sell our product candidates profitably, if they are approved for sale. The market for PB2452, PB1046, PB6440 or any other product candidates may be smaller than we expect. Our estimates of the potential market opportunity for PB2452, PB1046, PB6440 or any other product candidates include several key assumptions based on our industry knowledge, industry publications and third-party research reports. These assumptions include, for PB2452, the number of patients on ticagrelor who will experience uncontrolled major or life-threatening bleeding or who will require urgent surgery or an invasive procedure; for PB1046, the number of patients with PAH; and for PB6440, the number of patients with treatment-resistant hypertension, as well as the estimated reimbursement levels for each product candidate if approved. However, there can be no assurance that any of these assumptions are, or will remain, accurate. If the actual market for PB2452, PB1046, PB6440 or for any other product candidates we may develop is smaller than we expect, our revenues, if any, may be limited and it may be more difficult for us to achieve or maintain profitability. Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of any products that we may develop. We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials and will face an even greater risk if we commercially sell any products that we may develop. If we cannot successfully defend ourselves against claims that our product candidates or drugs caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in: • • • • • • • • decreased demand for any product candidates or drugs that we may develop; injury to our reputation and significant negative media attention; withdrawal of clinical trial participants; significant costs to defend the related litigation; substantial monetary awards paid to trial participants or patients; loss of revenue; reduced resources of our management to pursue our business strategy; and the inability to commercialize any products that we may develop. 49 We currently hold $5,000,000 in product liability insurance coverage in the aggregate, with a per incident limit of $5,000,000, which may not be adequate to cover all liabilities that we may incur. We may need to increase our insurance coverage as we expand our clinical trials or if we commence commercialization of our product candidates. Insurance coverage is increasingly expensive. We may not be able to maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise. Our business and operations would suffer in the event of computer system failures, cyberattacks or a deficiency in our cybersecurity. Despite the implementation of security measures, our internal computer systems, and those of third parties on which we rely, are vulnerable to damage from computer viruses, malware, natural disasters, terrorism, war, telecommunication and electrical failures, cyberattacks or cyber-intrusions over the Internet, attachments to emails, persons inside our organization, or persons with access to systems inside our organization. The risk of a security breach or disruption, particularly through cyberattacks or cyber intrusion, including by computer hackers, foreign governments, and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our product development programs. For example, the loss of clinical trial data from completed or ongoing or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach was to result in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur material legal claims and liability and damage to our reputation, and the further development of our product candidates could be delayed. Risks Related to Our Dependence on Third Parties We rely on third parties to conduct a significant portion of our existing clinical trials and potential future clinical trials for product candidates, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such trials. To date, we have generally engaged CROs to conduct our ongoing clinical trial of PB2452 and to assist in conducting portions of our ongoing clinical trial of PB1046. We expect to engage CROs for future clinical trials for PB2452, PB1046, PB6440 or other product candidates that we may progress to clinical development. In addition, pursuant to the SFJ Agreement, SFJ will have primary responsibility for clinical development and regulatory activities for PB2452 in China and Japan and will provide clinical trials operational support in the European Union. We expect to continue to rely on third parties, including clinical data management organizations, medical institutions and clinical investigators, to conduct those clinical trials. Any of these third parties may terminate their engagements with us, some in the event of an uncured material breach and some at any time for convenience. If any of our relationships with these third parties terminate, we may not be able to timely enter into arrangements with alternative third parties or to do so on commercially reasonable terms, if at all. Switching or adding CROs involves substantial cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines. Though we intend to carefully manage our relationships with our CROs, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects. Further, the performance of our CROs may also be interrupted by the ongoing COVID-19 pandemic, including due to travel or quarantine policies, heightened exposure of CRO staff who are healthcare providers to COVID-19 or prioritization of resources toward the pandemic. In addition, any third parties conducting our clinical trials will not be our employees, and except for remedies available to us under our agreements with such third parties, we cannot control whether or not they devote sufficient time and resources to our clinical programs. If these third parties do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our product candidates. Consequently, our results of operations and the commercial prospects for our product candidates would be harmed, our costs could increase substantially and our ability to generate revenue could be delayed significantly. We rely on these parties for execution of our preclinical studies and clinical trials, and generally do not control their activities. Our reliance on these third parties for research and development activities will reduce our control over these activities but will not relieve us of our responsibilities. For example, we will remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA requires us to comply with standards, commonly referred to as good clinical practices, or GCPs, for conducting, recording and 50 reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. We also are required to register ongoing clinical trials and post the results of completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within specified timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions. If we or any of our CROs or other third parties, including trial sites, fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA, EMA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials complies with GCP regulations. In addition, our clinical trials must be conducted with product produced under cGMP conditions. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process. In addition, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to the FDA. The FDA may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected interpretation of the trial. The FDA may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA and may ultimately lead to the denial of marketing approval of PB2452, PB1046, PB6440 or any other product candidates. We also expect to rely on other third parties to store and distribute product supplies for our clinical trials. Any performance failure on the part of our distributors could delay clinical development or marketing approval of our product candidates or commercialization of our products, producing additional losses and depriving us of potential revenue. We contract with third parties for the manufacture of PB2452 and PB1046 for clinical drug supply and expect to continue to do so for commercialization if approved. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts. We do not have any cGMP manufacturing facilities. We currently rely, and expect to continue to rely, on third parties for the cGMP manufacture of PB2452, PB1046, PB6440 and any other product candidates that we may pursue, for clinical development as well as for commercial manufacture of PB2452, PB1046, PB6440 and any other product candidates which we may pursue, if we receive marketing approval. We also rely on a proprietary E. coli strain owned by Wacker Biotech GmbH, or Wacker, which we have licensed for the production of PB2452. Our reliance on Wacker’s E. coli strain increases the risk that we will not have sufficient quantities of PB2452 or be able to obtain quantities at an acceptable cost or quality, which could delay, prevent or impair our ability to timely conduct our clinical trials or our other development or commercialization efforts. We will continue to rely on Wacker to manufacture our clinical supply of PB2452 for our ongoing clinical trials. We have also engaged BioVectra, another cGMP contract manufacturer, for our ongoing clinical trials and we intend to use BioVectra for commercial production of PB2452, if approved. With respect to PB2452, to date we have only relied upon Wacker for manufacture of drug substance for use in our initial clinical trials. As we scale our manufacturing of PB2452 to meet potential commercial demand, if PB2452 is approved, we have initiated a technology transfer of our current manufacturing process for PB2452 to BioVectra. We have engaged BioVectra to manufacture drug substance for our ongoing clinical trials and intend to engage BioVectra to manufacture commercial supply of PB2452, if approved. We will need to perform analytical and other tests to demonstrate that the new materials produced by Wacker, BioVectra, or any other future third-party manufacturer that we engage, are comparable in all respects to the product utilized in our previous clinical trials. There is no assurance that any such product will pass the required comparability testing, that any other future third- party manufacturer that we engage will be successful in producing PB2452 or that any materials produced by Wacker, BioVectra or any other third-party manufacturer that we engage will have the same effect in patients that we have observed to date with respect to materials used in our previous clinical trials. Moreover, if supplies are interrupted or produced in poor yield or quality, it would materially harm our business. BioVectra will be required to scale up the manufacturing process to meet our future needs of PB2452 for later-stage clinical development and, if approved, commercialization. If BioVectra is unable to successfully scale up the manufacturing process, we would need to find alternative manufacturing facilities or an alternative manufacturing process, which we may not be able to do on a timely basis or on commercially reasonable terms, if at all, and which could adversely affect the clinical development of PB2452. We also expect to rely on third-party manufacturers or third-party collaborators for the manufacture of commercial supply of PB2452, PB1046, PB6440 and any other product candidates for which we obtain marketing approval. The facilities used by our contract manufacturers to manufacture our product candidates must be inspected by the FDA or other regulatory authorities after we submit our BLA or comparable marketing application to the FDA or other regulatory authority. 51 We do not have control over a supplier’s or manufacturer’s compliance with laws, regulations and applicable cGMP standards or similar regulatory requirements and other laws and regulations, such as those related to environmental health and safety matters. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or other regulatory authorities, we may be unable to obtain regulatory approval of our marketing applications. In addition, we have no control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a comparable foreign regulatory authority finds deficiencies with or does not approve these facilities for the manufacture of our product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved. We may be unable to enter into any agreements with future third-party manufacturers or to do so on acceptable terms. Even if we enter into such agreements, qualifying and validating such manufacturers may take a significant period of time and reliance on third-party manufacturers entails additional risks, including: • • • • • • reliance on the third party for regulatory compliance and quality assurance; the possible breach of the manufacturing agreement by the third party; the incurrence of upfront scale-up costs prior to commercial approval; the possible misappropriation of our proprietary information, including our trade secrets and know-how; the possible increase in costs for the raw materials for our product candidates; and the possible termination or nonrenewal of any agreement by any third party at a time that is costly or inconvenient for us. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or drugs, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supply of our products. Our product candidates, and any drugs that we may develop, may compete with other product candidates and drugs for access to manufacturing facilities. The performance of our third-party manufacturers may also be interrupted by production shortages or other supply interruptions resulting from the ongoing COVID-19 pandemic. There are no assurances we would be able to enter into similar commercial arrangements with other manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us in a timely manner. Any performance failure on the part of our existing or future manufacturers could delay clinical development or marketing approval. We are collaborating with SFJ for the development of PB2452, and we may seek additional collaborations with third parties for the development or commercialization of our product candidates. If those collaborations are not successful, we may not be able to capitalize on the market potential of these product candidates. We are collaborating with SFJ for the development of PB2452. We may seek additional third-party collaborators for the development and commercialization of our product candidates, including for the commercialization of any of our product candidates that are approved for marketing outside the United States. Our likely collaborators for any such arrangements include regional and national pharmaceutical companies and biotechnology companies. If we enter into any additional such arrangements with any third parties, we will likely have limited control over the amount and timing of resources that our collaborators dedicate to the development or commercialization of our product candidates. Our ability to generate revenue from these arrangements will depend on our collaborators’ abilities to successfully perform the functions assigned to them in these arrangements. Collaborations involving our product candidates would pose the following risks to us: • • • collaborators have significant discretion in determining the efforts and resources that they will apply to these collaborations; collaborators may not perform their obligations as expected; collaborators may not pursue development and commercialization of any product candidates that achieve regulatory approval or may elect not to continue or renew development or commercialization programs based on clinical trial results, changes in the collaborators’ strategic focus or available funding, or external factors, such as an acquisition, that divert resources or create competing priorities; 52 • • • • • • • • collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing; collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our product candidates if the collaborators believe that competitive products are more likely to be successfully developed or can be commercialized under terms that are more economically attractive than ours; product candidates discovered in collaboration with us may be viewed by our collaborators as competitive with their own product candidates or drugs, which may cause collaborators to cease to devote resources to the commercialization of our product candidates; a collaborator with marketing and distribution rights to one or more of our product candidates that achieve regulatory approval may not commit sufficient resources to the marketing and distribution of such products; disagreements with collaborators, including disagreements over proprietary rights, contract interpretation or the preferred course of development, might cause delays or termination of the research, development or commercialization of product candidates, might lead to additional responsibilities for us with respect to product candidates, or might result in litigation or arbitration, any of which would be time-consuming and expensive; collaborators may not properly maintain or defend our or their intellectual property rights or may use our or their proprietary information in such a way as to invite litigation that could jeopardize or invalidate such intellectual property or proprietary information or expose us to potential litigation; collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability; and collaborations may be terminated for the convenience of the collaborator and, if terminated, we could be required to raise additional capital to pursue further development or commercialization of the applicable product candidates. Collaboration agreements may not lead to development or commercialization of product candidates in the most efficient manner or at all. If SFJ or any future collaborator of ours were to be involved in a business combination, the continued pursuit and emphasis on our product development or commercialization program could be delayed, diminished or terminated. We may seek to establish additional collaborations, and if we are unable to do so, we may have to alter our development and commercialization plans. Our product development programs and the potential commercialization of our product candidates will require substantial additional capital. We are collaborating with SFJ for the development of PB2452. For our other product candidates, we may decide to establish additional collaborations with pharmaceutical and biotechnology companies for the development and potential commercialization of those product candidates. We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for any collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by the FDA or similar regulatory authorities outside the United States, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge and industry and market conditions generally. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration could be more attractive than the one with us for our product candidate. Collaborations are complex and time-consuming to negotiate and document. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators. We may not be able to negotiate additional collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of such product candidate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any 53 sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate revenue. Risks Related to Our Intellectual Property If we are unable to obtain or protect intellectual property rights related to any of our product candidates, we may not be able to compete effectively in our market. We rely upon a combination of patents, trade secret protection and confidentiality agreements to protect the intellectual property related to our product candidates and our ELP technology. Our success depends in large part on our ability to obtain and maintain patent and other intellectual property protection in the United States and in other countries with respect to our proprietary technology and product candidates. As of the date of this Annual Report on Form 10-K, our patent estate contained at least 19 patent families that we own or in-license that protect various aspects of our product candidates or our ELP technology platform. We own or have rights in 22 United States patents, 18 United States patent applications, over 60 foreign patents and over 60 foreign patent applications. We cannot offer any assurances about which of our patent applications will issue, the breadth of any resulting patent or whether any of the issued patents will be found invalid and unenforceable or will be threatened by third parties. We cannot offer any assurances that the breadth of our granted patents will be sufficient to stop a competitor from developing and commercializing a product, including a biosimilar product that would be competitive with one or more of our product candidates. Furthermore, any successful challenge to these patents or any other patents owned by or licensed to us after patent issuance could deprive us of rights necessary for the successful commercialization of any of our product candidates. Further, if we encounter delays in regulatory approvals, the period of time during which we could market a product candidate under patent protection could be reduced. The patent prosecution process is expensive and time-consuming. We may not be able to prepare, file and prosecute all necessary or desirable patent applications at a commercially reasonable cost or in a timely manner or in all jurisdictions. It is also possible that we may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Moreover, depending on the terms of any future in-licenses to which we may become a party, we may not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the patents, covering technology in-licensed from third parties. Therefore, these patents and patent applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. In addition to the protection provided by our patent estate, we rely on trade secret protection and confidentiality agreements to protect proprietary know-how that is not amenable to patent protection. Although we generally require all of our employees to assign their inventions to us, and all of our employees, consultants, advisors and any third parties who have access to our proprietary know-how, information, or technology to enter into confidentiality agreements, we cannot provide any assurances that all such agreements have been duly executed, or that our trade secrets and other confidential proprietary information will not be disclosed. Moreover, our competitors may independently develop knowledge, methods and know-how equivalent to our trade secrets. Competitors could purchase our products, if approved, and replicate some or all of the competitive advantages we derive from our development efforts for technologies on which we do not have patent protection. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be harmed. We also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems. While we have confidence in these individuals, organizations and systems, our agreements or security measures may be breached, and we may not have adequate remedies for any breach. Also, if the steps taken to maintain our trade secrets are deemed inadequate, we may have insufficient recourse against third parties for misappropriating the trade secret. In addition, others may independently discover our trade secrets and proprietary information. For example, the FDA is considering whether to make additional information publicly available on a routine basis, including information that we may consider to be trade secrets or other proprietary information, and it is not clear at the present time how the FDA’s disclosure policies may change in the future. If we are unable to prevent material disclosure of the non-patented intellectual property related to our technologies to third parties, and there is no guarantee that we will have any such enforceable trade secret protection, we may not be able to establish or maintain a 54 competitive advantage in our market, which could materially adversely affect our business, results of operations and financial condition. Patent terms may be inadequate to protect our competitive position on our products for an adequate amount of time, and if we do not obtain protection under the Hatch-Waxman Amendments and similar non-United States legislation for extending the term of patents covering each of our product candidates, our business may be materially harmed. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. Depending upon the timing, duration and conditions of FDA marketing approval of our product candidates, one or more of our United States patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments, and similar legislation in the European Union. The Hatch-Waxman Amendments permit a patent term extension of up to five years for a patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval. Only one patent may be extended, and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended. However, we may not receive an extension if we fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements. Moreover, the length of the extension could be less than we request. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can enforce our patent rights for that product will be shortened and our competitors may obtain approval to market competing products sooner. As a result, our revenue from applicable products could be reduced and could have a material adverse effect on our business. If we fail to comply with our obligations in our current and future intellectual property licenses with third parties or the SFJ Agreement, we could lose rights that are important to our business. We are heavily reliant upon licenses to certain patent rights and proprietary technology for the development of PB2452, PB1046 and our ELP technology. These license agreements impose diligence, development and commercialization timelines and milestone payment, royalty, insurance and other obligations on us. If we fail to comply with our obligations, our licensors may have the right to terminate our licenses, in which event we might not be able to develop, manufacture or market any product that is covered by the intellectual property we in-license from such licensor and may face other penalties. Such an occurrence would materially adversely affect our business prospects. Licenses to additional third-party technology and materials that may be required for our development programs may not be available in the future or may not be available on commercially reasonable terms, or at all, which could have a material adverse effect on our business and financial condition. Although we control the prosecution, maintenance and enforcement of the licensed and sublicensed intellectual property relating to PB2452, we may require the cooperation of our licensors and any upstream licensor, which may not be forthcoming. Therefore, we cannot be certain that the prosecution, maintenance and enforcement of these patent rights will be in a manner consistent with the best interests of our business. If we or our licensor fail to maintain such patents, or if we or our licensor lose rights to those patents or patent applications, the rights we have licensed may be reduced or eliminated and our right to develop and commercialize any of our product candidates that are the subject of such licensed rights could be adversely affected. In addition to the foregoing, the risks associated with patent rights that we license from third parties will also apply to patent rights we may own in the future. Further, if we fail to comply with our development obligations under our license agreements, we may lose our patent rights with respect to such agreement on a territory-by-territory basis, which would affect our patent rights worldwide. Termination of our current or any future license agreements would reduce or eliminate our rights under these agreements and may result in our having to negotiate new or reinstated agreements with less favorable terms or cause us to lose our rights under these agreements, including our rights to important intellectual property or technology. Any of the foregoing could prevent us from commercializing our other product candidates, which could have a material adverse effect on our operating results and overall financial condition. In addition, intellectual property rights that we in-license in the future may be sublicenses under intellectual property owned by third parties, in some cases through multiple tiers. The actions of our licensors may therefore affect our rights to use our sublicensed intellectual property, even if we are in compliance with all of the obligations under our license agreements. Should our licensors or any of the upstream licensors fail to comply with their obligations under the agreements pursuant to which they obtain the rights that are sublicensed to us, or should such agreements be terminated or amended, our ability to develop and commercialize our product candidates may be materially harmed. 55 Further, we have granted SFJ a security interest in all of our assets related to PB2452, pursuant to the SFJ Agreement. If we are unable to meet our payment obligations to SFJ, SFJ may exercise its remedies as a holder of a first priority security interest, which would result in a loss of our PB2452 intellectual property rights and our business would be materially harmed. Patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our future patents. Our ability to obtain patents is highly uncertain because, to date, some legal principles remain unresolved, and there has not been a consistent policy regarding the breadth or interpretation of claims allowed in patents in the United States. Furthermore, the specific content of patents and patent applications that are necessary to support and interpret patent claims is highly uncertain due to the complex nature of the relevant legal, scientific, and factual issues. Changes in either patent laws or interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property or narrow the scope of our patent protection. For example, on September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act included a number of significant changes to United States patent law. These included provisions that affect the way patent applications will be prosecuted and may also affect patent litigation. The United States Patent and Trademark Office, or USPTO, has developed new and untested regulations and procedures to govern the full implementation of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy- Smith Act, and in particular, the first to file provisions, became effective in March 2013. The Leahy-Smith Act has also introduced procedures making it easier for third parties to challenge issued patents, as well as to intervene in the prosecution of patent applications. Finally, the Leahy-Smith Act contained new statutory provisions that require the USPTO to issue new regulations for their implementation, and it may take the courts years to interpret the provisions of the new statute. It is too early to tell what, if any, impact the Leahy-Smith Act will have on the operation of our business and the protection and enforcement of our intellectual property. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our future patents. Further, the United States Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on actions by the United States Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce patents that we have owned or licensed or that we might obtain in the future. An inability to obtain, enforce, and defend patents covering our proprietary technologies would materially and adversely affect our business prospects and financial condition. Similarly, changes in patent laws and regulations in other countries or jurisdictions, changes in the governmental bodies that enforce them or changes in how the relevant governmental authority enforces patent laws or regulations may weaken our ability to obtain new patents or to enforce patents that we may obtain in the future. Further, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws of the United States. As a result, we may encounter significant problems in protecting and defending our intellectual property both in the United States and abroad. For example, if the issuance in a given country of a patent covering an invention is not followed by the issuance in other countries of patents covering the same invention, or if any judicial interpretation of the validity, enforceability or scope of the claims or the written description or enablement, in a patent issued in one country is not similar to the interpretation given to the corresponding patent issued in another country, our ability to protect our intellectual property in those countries may be limited. Changes in either patent laws or in interpretations of patent laws in the United States and other countries may materially diminish the value of our intellectual property or narrow the scope of our patent protection. We may be involved in lawsuits to protect or enforce our patents, which could be expensive, time consuming and unsuccessful. Competitors may infringe the patents we have applied for. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. If we initiate legal proceedings against a third party to enforce a patent covering one of our product candidates, the defendant could counterclaim that the patent covering our product or product candidate is invalid and/or unenforceable. In patent litigation in the United States, counterclaims alleging invalidity and/or unenforceability are common, and there are numerous grounds upon which a third party can assert invalidity or unenforceability of a patent. In an infringement proceeding, a court may decide that the patent claims we are asserting are invalid and/or unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patent claims do not cover the technology in question. Third parties may also raise similar claims before administrative bodies in the United States or abroad, even outside the context of litigation. Such mechanisms include re- 56 examination, post grant review, inter partes review and equivalent proceedings in foreign jurisdictions (for example, opposition proceedings). Such proceedings could result in revocation of or amendment to our patents in such a way that they no longer cover our product candidates. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we, our patent counsel, and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on our product candidates. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly, could put our patent applications at risk of not issuing and could have a material adverse impact on our business. Interference proceedings provoked by third parties or brought by us may be necessary to determine the priority of inventions with respect to our patent applications. An unfavorable outcome could require us to cease using the related technology or force us to take a license under the patent rights of the prevailing party, if available. Furthermore, our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Our defense of litigation or interference proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees. We may not be able to prevent misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the United States. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. There could also be public announcements of the results of hearings, motions, or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of our common stock. We may be unsuccessful in licensing or acquiring intellectual property from third parties that may be required to develop and commercialize our product candidates. A third party may hold intellectual property, including patent rights that are important or necessary to the development and commercialization of our product candidates. It may be necessary for us to use the patented or proprietary technology of third parties to commercialize our product candidates, in which case we would be required to acquire or obtain a license to such intellectual property from these third parties, and we may be unable to do so on commercially reasonable terms or at all. The licensing or acquisition of third-party intellectual property rights is a competitive area, and several more established companies may pursue strategies to license or acquire third-party intellectual property rights that we may consider attractive or necessary. These established companies may have a competitive advantage over us due to their size, capital resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return on our investment or at all. If we are unable to successfully obtain rights to required third-party intellectual property rights or maintain the existing intellectual property rights we have, we may have to abandon development of the relevant program or product candidate, which could have a material adverse effect on our business. Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain. As our current and future product candidates progress toward commercialization, the possibility of a patent infringement claim against us increases. We cannot provide any assurance that our current and future product candidates do not infringe other parties’ patents or other proprietary rights, and competitors or other parties may assert that we infringe their proprietary rights in any event. We may become party to, or threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect to our current and future product candidates, including interference or derivation proceedings before the USPTO. Even if we believe such claims are without merit, a court of competent jurisdiction could hold that these third-party patents are valid, enforceable and infringed, which could have a negative impact on our ability to commercialize PB2452, PB1046, PB6440 or any future product candidates. In order to successfully challenge the validity of any such United States patent in federal court, we would need to overcome a presumption of validity. As this burden is high and requires us to present clear and convincing evidence as to the invalidity of any such United States patent claim, there is no assurance that a court of competent jurisdiction would agree with us and invalidate the claims of any such United States patent. Moreover, given the vast number of patents in our field of technology, we cannot be certain that we do not infringe existing patents or that we will not infringe patents that may be granted in the future. 57 While we may decide to initiate proceedings to challenge the validity of these or other patents in the future, we may be unsuccessful, and courts or patent offices in the United States and abroad could uphold the validity of any such patent. Furthermore, because patent applications can take many years to issue and may be confidential for 18 months or more after filing, and because pending patent claims can be revised before issuance, there may be applications now pending which may later result in issued patents that may be infringed by the manufacture, use or sale of our product candidates. Regardless of when filed, we may fail to identify relevant third-party patents or patent applications, or we may incorrectly conclude that a third-party patent is invalid or not infringed by our product candidates or activities. If a patent holder believes that one of our product candidates infringes its patent, the patent holder may sue us even if we have received patent protection for our technology. Moreover, we may face patent infringement claims from non- practicing entities that have no relevant drug revenue and against whom our own patent portfolio may thus have no deterrent effect. If a patent infringement suit were threatened or brought against us, we could be forced to stop or delay research, development, manufacturing or sales of the drug or product candidate that is the subject of the actual or threatened suit. If we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license from such third party to continue commercializing our product candidates. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if a license can be obtained on acceptable terms, the rights may be non-exclusive, which could give our competitors access to the same technology or intellectual property rights licensed to us. If we fail to obtain a required license, we may be unable to effectively market product candidates based on our technology, which could limit our ability to generate revenue or achieve profitability and possibly prevent us from generating revenue sufficient to sustain our operations. Alternatively, we may need to redesign our infringing products, which may be impossible or require substantial time and monetary expenditure. Under certain circumstances, we could be forced, including by court orders, to cease commercializing our product candidates. In addition, in any such proceeding or litigation, we could be found liable for substantial monetary damages, potentially including treble damages and attorneys’ fees, if we are found to have willfully infringed the patent at issue. A finding of infringement could prevent us from commercializing our product candidates or force us to cease some of our business operations, which could harm our business. Any claims by third parties that we have misappropriated their confidential information or trade secrets could have a similar negative impact on our business. The cost to us in defending or initiating any litigation or other proceeding relating to patent or other proprietary rights, even if resolved in our favor, could be substantial, and litigation would divert our management’s attention. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could delay our research and development efforts and limit our ability to continue our operations. We may be subject to claims that our employees, consultants, or independent contractors have wrongfully used or disclosed confidential information of third parties. We employ individuals who were previously employed at other biotechnology or biopharmaceutical companies. Although we try to ensure that our employees, consultants and advisors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or our employees, consultants, or independent contractors have inadvertently or otherwise used or disclosed confidential information of our employees’ former employers or other third parties. We may also be subject to claims that former employers or other third parties have an ownership interest in our future patents. Litigation may be necessary to defend against these claims. There is no guarantee of success in defending these claims, and even if we are successful, litigation could result in substantial cost and be a distraction to our management and other employees. We may be subject to claims challenging the inventorship or ownership of our future patents and other intellectual property. We may also be subject to claims that former employees, collaborators, or other third parties have an ownership interest in our patent applications, our future patents, or other intellectual property. We may be subject to ownership disputes in the future arising, for example, from conflicting obligations of consultants or others who are involved in developing our product candidates. Although it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own, and we cannot be certain that our agreements with such parties will be upheld in the face of a potential challenge, or that they will not be breached, for which we may not have an adequate remedy. The assignment of intellectual property rights may not be self-executing or the assignment agreements may be breached, and litigation may be necessary to defend against these and other claims challenging inventorship or ownership. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, valuable intellectual property. Such an outcome could have a material adverse effect on our business. Even if we 58 are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees. Reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed. If we rely on third parties to manufacture or commercialize PB2452, PB1046, PB6440 or any future product candidates, or if we collaborate with additional third parties for the development of PB2452, PB1046, PB6440 or any future product candidates, we must, at times, share trade secrets with them. We may also conduct joint research and development programs that may require us to share trade secrets under the terms of our research and development partnerships or similar agreements. We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if applicable, material transfer agreements, consulting agreements or other similar agreements with our advisors, employees, third-party contractors and consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information, including our trade secrets. Despite the contractual provisions employed when working with third parties, the need to share trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or other unauthorized use or disclosure could have an adverse effect on our business and results of operations. In addition, these agreements typically restrict the ability of our advisors, employees, third-party contractors and consultants to publish data potentially relating to our trade secrets. Despite our efforts to protect our trade secrets, we may not be able to prevent the unauthorized disclosure or use of our technical know-how or other trade secrets by the parties to these agreements. Moreover, we cannot guarantee that we have entered into such agreements with each party that may have or have had access to our confidential information or proprietary technology and processes. Monitoring unauthorized uses and disclosures is difficult, and we do not know whether the steps we have taken to protect our proprietary technologies will be effective. If any of the collaborators, scientific advisors, employees, contractors and consultants who are parties to these agreements breaches or violates the terms of any of these agreements, we may not have adequate remedies for any such breach or violation, and we could lose our trade secrets as a result. Moreover, if confidential information that is licensed or disclosed to us by our partners, collaborators, or others is inadvertently disclosed or subject to a breach or violation, we may be exposed to liability to the owner of that confidential information. Enforcing a claim that a third party illegally obtained and is using our trade secrets, like patent litigation, is expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the United States are sometimes less willing to protect trade secrets. We may enjoy only limited geographical protection with respect to certain patents and we may not be able to protect our intellectual property rights throughout the world. Filing and prosecuting patent applications and defending patents covering our product candidates in all countries throughout the world would be prohibitively expensive. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we have patent protection, but enforcement rights are not as strong as that in the United States or Europe. These products may compete with our product candidates, and our future patents or other intellectual property rights may not be effective or sufficient to prevent them from competing. In addition, we may decide to abandon national and regional patent applications before they are granted. The examination of each national or regional patent application is an independent proceeding. As a result, patent applications in the same family may issue as patents in some jurisdictions, such as in the United States, but may issue as patents with claims of different scope or may even be refused in other jurisdictions. It is also quite common that depending on the country, the scope of patent protection may vary for the same product candidate or technology. While we intend to protect our intellectual property rights in our expected significant markets, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market our product candidates. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate, which may have an adverse effect on our ability to successfully commercialize our product candidates in all of our expected significant foreign markets. If we encounter difficulties in protecting, or are otherwise precluded from effectively protecting, the intellectual property rights important for our business in such jurisdictions, the value of these rights may be diminished, and we may face additional competition from others in those jurisdictions. 59 The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws or rules and regulations in the United States and Europe, and many companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets, and other intellectual property rights, which could make it difficult for us to stop the infringement of our future patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in other jurisdictions, whether or not successful, could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our future patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing as patents, and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license. Some countries also have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, some countries limit the enforceability of patents against government agencies or government contractors. In those countries, the patent owner may have limited remedies, which could materially diminish the value of such patents. If we are forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired. Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment, and other requirements imposed by government patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements. Periodic maintenance fees, renewal fees, annuity fees and various other government fees on patents and/or applications will be due to be paid to the USPTO and various government patent agencies outside of the United States over the lifetime of our patents and/or applications and any patent rights we may obtain in the future. Furthermore, the USPTO and various non-United States government patent agencies require compliance with several procedural, documentary, fee payment and other similar provisions during the patent application process. In many cases, an inadvertent lapse of a patent or patent application can be cured by payment of a late fee or by other means in accordance with the applicable rules. There are situations, however, in which non-compliance can result in abandonment or lapse of the patents or patent applications, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, potential competitors might be able to enter the market, which could have a material adverse effect on our business. Any trademarks we have obtained or may obtain may be infringed or otherwise violated, or successfully challenged, resulting in harm to our business. We expect to rely on trademarks as one means to distinguish our product candidates, if approved for marketing, from the drugs of our competitors. Once we select new trademarks and apply to register them, our trademark applications may not be approved. Third parties may oppose or attempt to cancel our trademark applications or trademarks, or otherwise challenge our use of the trademarks. In the event that our trademarks are successfully challenged, we could be forced to rebrand our drugs, which could result in loss of brand recognition and could require us to devote resources to advertising and marketing new brands. Our competitors may infringe or otherwise violate our trademarks and we may not have adequate resources to enforce our trademarks. Any of the foregoing events may have a material adverse effect on our business. Intellectual property rights do not necessarily address all potential threats to our competitive advantage. The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may not adequately protect our business or permit us to maintain our competitive advantage. The following examples are illustrative: • • • • others may be able to make products that are similar to or otherwise competitive with our product candidates but that are not covered by the claims of our current or future patents; an in-license necessary for the manufacture, use, sale, offer for sale or importation of one or more of our product candidates may be terminated by the licensor; we or future collaborators might not have been the first to make the inventions covered by our issued or future issued patents or our pending patent applications; we or future collaborators might not have been the first to file patent applications covering certain of our inventions; 60 • • • • • • • others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual property rights; it is possible that our pending patent applications will not lead to issued patents; issued patents that we own or in-license may be held invalid or unenforceable as a result of legal challenges by our competitors; issued patents that we own or in-license may not provide coverage for all aspects of our product candidates in all countries; our competitors might conduct research and development activities in countries where we do not have patent rights and then use the information learned from such activities to develop competitive products for sale in our major commercial markets; we may not develop additional proprietary technologies that are patentable; and the patents of others may have an adverse effect on our business. Should any of these events occur, they could significantly harm our business, results of operations and prospects. Risks Related to Legal and Regulatory Compliance Matters Our relationships with customers, healthcare providers, physicians and third-party payors are subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws, health information privacy and security laws, and other healthcare laws and regulations. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties. Healthcare providers, physicians and third-party payors in the United States and elsewhere will play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Our current and future arrangements with healthcare professionals, principal investigators, consultants, customers and third-party payors subject us to various federal and state fraud and abuse laws and other healthcare laws, including, without limitation, the federal Anti-Kickback Statute, the federal civil and criminal false claims laws and the law commonly referred to as the Physician Payments Sunshine Act and regulations promulgated under such laws. These laws will impact, among other things, our clinical research, proposed sales, marketing and educational programs, and other interactions with healthcare professionals. In addition, we may be subject to patient privacy laws by both the federal government and the states in which we conduct or may conduct our business. The laws that will affect our operations include, but are not limited to: • • the federal Anti-Kickback Statute, which prohibits, among other things, individuals or entities from knowingly and willfully soliciting, receiving, offering or paying any remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind in return for, or to induce, either the referral of an individual, or the purchase, lease, order or arrangement for or recommendation of the purchase, lease, order or arrangement for any good, facility, item or service for which payment may be made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs. The term “remuneration” has been broadly interpreted to include anything of value. Although there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor. A person does not need to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation. In addition, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, the ACA, signed into law in 2010, provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims Act; the federal civil and criminal false claims laws, including, without limitation, the federal False Claims Act, which can be enforced by private citizens through civil whistleblower or qui tam actions, and civil monetary penalty laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment or approval from the federal government, including Medicare, Medicaid and other government payors, that are false or fraudulent or knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim or to avoid, decrease or conceal an obligation to pay money to the federal government. A claim 61 • • • • includes “any request or demand” for money or property presented to the United States federal government. Several pharmaceutical and other healthcare companies have been prosecuted under these laws for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of products for unapproved, and thus non-reimbursable, uses; the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created additional federal criminal statutes which prohibit, among other things, a person from knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation; HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their implementing regulations, which imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information on health plans, healthcare clearinghouses and certain healthcare providers, known as “covered entities”, and their respective HIPAA “business associates”, and independent contractors that perform certain services involving the use or disclosure of individually identifiable health information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA and seek attorneys’ fees and costs associated with pursuing federal civil actions; the federal transparency laws, including the federal Physician Payments Sunshine Act, which requires certain manufacturers of drugs, medical devices, biologicals and medical supplies for which payment is available under Medicare, Medicaid or the State Children’s Health Insurance Program, with specific exceptions, to report annually to the Centers for Medicare & Medicaid Services, or CMS, information related to: (1) payments or other “transfers of value’’ made to physicians, as defined by such law, and teaching hospitals, and (2) ownership and investment interests held by physicians and their immediate family members; and state and foreign law equivalents of each of the above federal laws and regulations; state laws that require manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers, marketing expenditures or drug pricing; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, or that otherwise restrict payments that may be made to healthcare providers; state and local laws that require the registration of pharmaceutical sales representatives; and state and foreign laws that govern the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts. For example, the General Data Protection Regulation (EU) 2016/679, or GDPR, which went into effect on May 25, 2018, imposes privacy and security obligations on any entity that collects and/or processes health data from individuals located in the European Union. Under the GDPR, fines of up to 20 million Euros or up to 4% of the annual global turnover of the infringer, whichever is greater, could be imposed for significant non-compliance. In addition, on June 28, 2018, California enacted the California Consumer Privacy Act, or CCPA, which took effect on January 1, 2020. The CCPA gives California residents expanded rights to access and delete their personal information, opt out of certain personal information sharing, and receive detailed information about how their personal information is used. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. Some observers have noted that the CCPA could mark the beginning of a trend toward more stringent state privacy legislation in the United States, which could increase our potential liability and adversely affect our business. As well as complicating our compliance efforts, non-compliance with these laws could result in penalties or significant legal liability. Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, 62 regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant penalties, including, without limitation, civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participating in federal and state funded healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, contractual damages, diminished profits and future earnings, reputational harm and the curtailment or restructuring of our operations, any of which could harm our business. The risk of our being found in violation of these laws is increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply with multiple jurisdictions with different compliance and/or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements. Even if we obtain regulatory approval for PB2452, PB1046, PB6440 or any future product candidates, they will remain subject to ongoing regulatory oversight. Even if we obtain any regulatory approval for PB2452, PB1046, PB6440 or any future product candidates, such product candidates, once approved, will be subject to ongoing regulatory requirements applicable to manufacturing, labeling, packaging, storage, advertising, promoting, sampling, record-keeping and submitting of safety and other post-market information, among other things. Any regulatory approvals that we receive for PB2452, PB1046, PB6440 or any future product candidates may also be subject to a risk evaluation and mitigation strategy, limitations on the approved indicated uses for which the drug may be marketed or to the conditions of approval, or requirements that we conduct potentially costly post-marketing testing, including Phase 4 trials, and in the event that we receive accelerated approval of PB2452, the completion of a Phase 3 trial, and surveillance to monitor the quality, safety and efficacy of the drug. An unsuccessful post-marketing study or failure to complete such a study could result in the withdrawal of marketing approval. We will further be required to immediately report any serious and unexpected adverse events and certain quality or production problems with our products to regulatory authorities along with other periodic reports. Any new legislation addressing drug safety issues could result in delays in product development or commercialization, or increased costs to assure compliance. We will also have to comply with requirements concerning advertising and promotion for our products. Promotional communications with respect to prescription drug products are subject to a variety of legal and regulatory restrictions and must be consistent with the information in the product’s approved label. As such, we will not be allowed to promote our products for indications or uses for which they do not have approval, commonly known as off-label promotion. The holder of an approved BLA must submit new or supplemental applications and obtain prior approval for certain changes to the approved product, product labeling, or manufacturing process. In addition, drug manufacturers are subject to payment of user fees and continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP requirements and adherence to commitments made in the BLA or NDA or foreign marketing application. If we, or a regulatory authority, discover previously unknown problems with a drug, such as adverse events of unanticipated severity or frequency, or problems with the facility where the drug is manufactured or if a regulatory authority disagrees with the promotion, marketing or labeling of that drug, a regulatory authority may impose restrictions relative to that drug, the manufacturing facility or us, including requesting a recall or requiring withdrawal of the drug from the market or suspension of manufacturing. If we fail to comply with applicable regulatory requirements following approval of PB2452, PB1046, PB6440 or any future product candidates, a regulatory authority may: • • • • • issue an untitled letter or warning letter asserting that we are in violation of the law; seek an injunction or impose administrative, civil or criminal penalties or monetary fines; suspend or withdraw regulatory approval; suspend any ongoing clinical trials; refuse to approve a pending BLA, NDA or comparable foreign marketing application (or any supplements thereto) submitted by us or our strategic partners; 63 • • • • restrict the marketing or manufacturing of the drug; seize or detain the drug or otherwise require the withdrawal of the drug from the market; refuse to permit the import or export of product candidates; or refuse to allow us to enter into supply contracts, including government contracts. Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize PB2452, PB1046, PB6440 or any future product candidates and harm our business, financial condition, results of operations and prospects. Healthcare legislative or regulatory reform measures may have a negative impact on our business and results of operations. In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities, and affect our ability to profitably sell any product candidates for which we obtain marketing approval. Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. In March 2010, the ACA was passed, which substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts the United States pharmaceutical industry. The ACA, among other things: (1) established an annual, nondeductible fee on any entity that manufactures or imports certain specified branded prescription drugs and biologic agents apportioned among these entities according to their market share in some government healthcare programs; (2) expanded the entities eligible for discounts under the 340B drug pricing program; (3) increased the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13% of the average manufacturer price for most branded and generic drugs, respectively, and capped the total rebate amount for innovator drugs at 100% of the Average Manufacturer Price, or AMP; (4) expanded the eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals and by adding new mandatory eligibility categories for individuals with income at or below 133% of the federal poverty level, thereby potentially increasing manufacturers’ Medicaid rebate liability; (5) addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for certain drugs and biologics that are inhaled, infused, instilled, implanted or injected; (6) introduced a new Medicare Part D coverage gap discount program in which manufacturers must now agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D; (7) created a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research; and (8) established a Center for Medicare and Medicaid Innovation at CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug. There remain judicial and Congressional challenges to certain aspects of the ACA, as well as recent efforts by the Trump administration to repeal or replace certain aspects of the ACA. While Congress has not passed comprehensive repeal legislation, bills affecting the implementation of certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs Act of 2017, or Tax Act, includes a provision that repealed, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” In addition, the 2020 federal spending package permanently eliminates, effective January 1, 2020, the ACA-mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax and, effective January 1, 2021, also eliminates the health insurer tax. The Bipartisan Budget Act of 2018, or the BBA, among other things, amended the ACA, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole.” In December 2018, CMS published a new final rule permitting further collections and payments to and from certain ACA qualified health plans and health insurance issuers under the ACA risk adjustment program in response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. On December 14, 2018, a Texas United States District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the Tax Act. Additionally, on December 18, 2019, the United States Court of Appeals for the 5th Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining provisions of the ACA 64 are invalid as well. It is unclear how this decision, future decisions, subsequent appeals, and other efforts to repeal and replace the ACA will impact the ACA and our business. Other legislative changes have been proposed and adopted since the ACA was enacted. These changes include aggregate reductions to Medicare payments to providers of 2% per fiscal year pursuant to the Budget Control Act of 2011, which began in 2013, and due to subsequent legislative amendments to the statute, including the BBA, will remain in effect through 2029, unless additional Congressional action is taken. The American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to several providers, including hospitals and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These laws may result in additional reductions in Medicare and other healthcare funding, which could have an adverse effect on customers for our product candidates, if approved, and, accordingly, our financial operations. Additionally, there has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. At the federal level, the Trump administration’s budget proposal for fiscal year 2020 contains further drug price control measures that could be enacted during the budget process or in other future legislation, including, for example, measures to permit Medicare Part D plans to negotiate the price of certain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid, and to eliminate cost sharing for generic drugs for low-income patients. Further, the Trump administration released a plan to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase drug manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products, and reduce the out of pocket costs of drug products paid by consumers. The Department of Health and Human Services has started soliciting feedback on some of these measures and, at the same, is immediately implementing others under its existing authority. For example, in May 2019, CMS issued a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning January 1, 2020. This final rule codified CMS's policy change that was effective January 1, 2019. While some of these and other measures may require additional authorization to become effective, Congress and the Trump administration have indicated that they will continue to seek new legislative and/or administrative measures to control drug costs. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. We expect that these and other healthcare reform measures that may be adopted in the future may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved drug. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our drugs. In addition, FDA regulations and guidance may be revised or reinterpreted by the FDA in ways that may significantly affect our business and our products. The Trump administration has also taken several executive actions, including the issuance of a number of Executive Orders, that could impose significant burdens on, or otherwise materially delay, the FDA’s ability to engage in routine oversight activities such as implementing statutes through rulemaking, issuance of guidance, and review and approval of marketing applications. It is difficult to predict how these requirements will be interpreted and implemented and the extent to which they will impact the FDA’s ability to exercise its regulatory authority. If these executive actions impose restrictions on the FDA’s ability to engage in oversight and implementation activities in the normal course, our business may be negatively impacted. Any new regulations or guidance, or revisions or reinterpretations of existing regulations or guidance, may impose additional costs or lengthen FDA review times for PB2452, PB1046, PB6440 or any future product candidates. We cannot determine how changes in regulations, statutes, policies, or interpretations when and if issued, enacted or adopted, may affect our business in the future. Such changes could, among other things, require: • • • • additional clinical trials to be conducted prior to obtaining approval; changes to manufacturing methods; recalls, replacements, or discontinuance of one or more of our products; and additional recordkeeping. 65 Such changes would likely require substantial time and impose significant costs, or could reduce the potential commercial value of PB2452, PB1046, PB6440 or other product candidates, and could materially harm our business and our financial results. In addition, delays in receipt of or failure to receive regulatory clearances or approvals for any other products would harm our business, financial condition, and results of operations. Our business activities will be subject to the Foreign Corrupt Practices Act, or FCPA, and similar anti-bribery and anti-corruption laws. As we expand our business activities outside of the United States, including our clinical trial efforts, we will be subject to the FCPA and similar anti-bribery or anti-corruption laws, regulations or rules of other countries in which we operate. The FCPA generally prohibits offering, promising, giving, or authorizing others to give anything of value, either directly or indirectly, to a non-United States government official in order to influence official action, or otherwise obtain or retain business. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect the transactions of the corporation and to devise and maintain an adequate system of internal accounting controls. Our business is heavily regulated and therefore involves significant interaction with public officials, including officials of non-United States governments. Additionally, in many other countries, the healthcare providers who prescribe pharmaceuticals are employed by their government, and the purchasers of pharmaceuticals are government entities; therefore, our dealings with these prescribers and purchasers will be subject to regulation under the FCPA. Recently the SEC and Department of Justice have increased their FCPA enforcement activities with respect to biotechnology and pharmaceutical companies. There is no certainty that all of our employees, agents, suppliers, manufacturers, contractors, or collaborators, or those of our affiliates, will comply with all applicable laws and regulations, particularly given the high level of complexity of these laws. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers, or our employees, the closing down of facilities, including those of our suppliers and manufacturers, requirements to obtain export licenses, cessation of business activities in sanctioned countries, implementation of compliance programs, and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our products in one or more countries as well as difficulties in manufacturing or continuing to develop our products, and could materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, and our business, prospects, operating results, and financial condition. Risks Related to Employee Matters and Managing Our Growth Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel. We are highly dependent on the management, development, clinical, financial and business development expertise of our executive officers, particularly Jonathan P. Mow, our Chief Executive Officer. Each of our executive officers may currently terminate their employment with us at any time. We do not maintain “key person” insurance for any of our executives or employees. Recruiting and retaining qualified scientific and clinical personnel and, if we progress the development of our product pipeline toward scaling up for commercialization, manufacturing and sales and marketing personnel, will also be critical to our success. The loss of the services of our executive officers or other key employees could impede the achievement of our development and commercialization objectives and seriously harm our ability to successfully implement our business strategy. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain regulatory approval of and commercialize products. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our development and commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited. We expect to expand our clinical development and regulatory capabilities and potentially implement sales, marketing and distribution capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations. As of December 31, 2019, we had approximately 40 employees. As our development progresses, we expect to experience significant growth in the number of our employees and the scope of our operations, particularly in the areas of 66 clinical product development, regulatory affairs and, if any of our product candidates receives marketing approval, sales, marketing and distribution. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations. Our employees, independent contractors, consultants, commercial collaborators, principal investigators, CROs, suppliers and vendors may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements. We are exposed to the risk that our employees, independent contractors, consultants, commercial collaborators, principal investigators, CROs, suppliers and vendors may engage in fraudulent conduct or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct or disclosure of unauthorized activities to us that violates FDA regulations, including those laws requiring the reporting of true, complete and accurate information to the FDA, manufacturing standards, federal and state healthcare laws and regulations, and laws that require the true, complete and accurate reporting of financial information or data. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Misconduct by these parties could also involve the improper use of individually identifiable information, including, without limitation, information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. We have adopted a code of business conduct and ethics, but it is not always possible to identify and deter misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant civil, criminal and administrative penalties, including, without limitation, damages, fines, disgorgement, imprisonment, exclusion from participation in government healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations. Risks Related to Ownership of Our Common Stock and Our Status as a Public Company An active trading market for our common stock may not continue to be developed or sustained. Prior to our initial public offering, there was no public market for our common stock, and we cannot assure you that an active trading market for our shares will continue to develop or be sustained. As a result, it may be difficult for you to sell shares at an attractive price or at all. The trading price of the shares of our common stock may be volatile, and purchasers of our common stock could incur substantial losses. Our stock price has been, and may continue to be, volatile. Since our IPO, our common stock has traded at prices ranging from $2.55 to $16.65 per share. The stock market in general and the market for biopharmaceutical companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors may not be able to sell their common stock at or above the price paid for the shares. The market price for our common stock may be influenced by many factors, including: • • • the commencement, enrollment or results of our clinical trials of PB2452, PB1046, PB6440 or any future clinical trials we may conduct, or changes in the development status of our product candidates; any delay in our regulatory filings for PB2452, PB1046, PB6440 or any other product candidate we may develop, and any adverse development or perceived adverse development with respect to the applicable regulatory authority’s review of such filings, including without limitation the FDA’s issuance of a “refusal to file” letter or a request for additional information; adverse results from, delays in or termination of clinical trials; 67 • • • • • • • • • • • • • • • • • • • adverse regulatory decisions, including failure to receive regulatory approval of our product candidates; unanticipated serious safety concerns related to the use of PB2452, PB1046, PB6440 or any other product candidate; changes in financial estimates by us or by any equity research analysts who might cover our stock; conditions or trends in our industry; changes in the market valuations of similar companies; stock market price and volume fluctuations of comparable companies and, in particular, those that operate in the biopharmaceutical industry; publication of research reports about us or our industry or positive or negative recommendations or withdrawal of research coverage by securities analysts; announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures; progress under our collaboration with SFJ for the development of PB2452; announcements of investigations or regulatory scrutiny of our operations or lawsuits filed against us; investors’ general perception of our company and our business; recruitment or departure of key personnel; overall performance of the equity markets; trading volume of our common stock; disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our technologies; significant lawsuits, including patent or stockholder litigation; changes in the structure of healthcare payment systems; general political and economic conditions; and other events or factors, many of which are beyond our control. The stock market in general, and the Nasdaq Global Market and biotechnology companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies, including very recently in connection with the ongoing COVID-19 pandemic, which has resulted in decreased stock prices for many companies notwithstanding the lack of a fundamental change in their underlying business models or prospects. Broad market and industry factors, including potentially worsening economic conditions and other adverse effects or developments relating to the ongoing COVID-19 pandemic, may negatively affect the market price of our common stock, regardless of our actual operating performance. The realization of any of the above risks or any of a broad range of other risks, including those described in this section, could have a significant and material adverse impact on the market price of our common stock. In addition, in the past, stockholders have initiated class action lawsuits against pharmaceutical and biotechnology companies following periods of volatility in the market prices of these companies’ stock. Such litigation, if instituted against us, could cause us to incur substantial costs and divert management’s attention and resources from our business. If equity research analysts do not publish research or reports, or publish unfavorable research or reports, about us, our business or our market, our stock price and trading volume could decline. The trading market for our common stock will be influenced by the research and reports that equity research analysts publish about us and our business. As a newly public company, we have only limited research coverage by equity research analysts. Equity research analysts may elect not to provide research coverage of our common stock, and such lack of research coverage may adversely affect the market price of our common stock. In the event we do have equity research analyst coverage, we will not have any control over the analysts or the content and opinions included in their reports. The price of our stock could decline if one or more equity research analysts downgrade our stock or issue other unfavorable commentary or research. If one or more equity research analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which in turn could cause our stock price or trading volume to decline. 68 A significant portion of our total outstanding shares are available for immediate resale. This could cause the market price of our common stock to drop significantly, even if our business is doing well. Sales of a substantial number of shares of our common stock in the public market could occur at any time. If our stockholders sell, or the market perceives that our stockholders intend to sell, substantial amounts of our common stock in the public market, the market price of our common stock could decline significantly. In addition, we have filed registration statements on Form S-8 registering the issuance of common stock subject to options or other equity awards issued or reserved for future issuance under our equity incentive plans. Shares registered under these registration statements on Form S-8 will be available for sale in the public market subject to vesting arrangements and exercise of options and the restrictions of Rule 144 in the case of our affiliates. Additionally, the holders of approximately 7.0 million shares of our common stock, or their transferees, have rights, subject to some conditions, to require us to file one or more registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or other stockholders. If we were to register the resale of these shares, they could be freely sold in the public market. If these additional shares are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline. The issuance of additional stock in connection with financings, acquisitions, investments, our equity incentive plan or otherwise will dilute all other stockholders. Our certificate of incorporation authorizes us to issue up to 200,000,000 shares of common stock and up to 10,000,000 shares of preferred stock with such rights and preferences as may be determined by our board of directors. Subject to compliance with applicable rules and regulations, in the future we may issue common stock or other securities convertible into shares of our common stock from time to time in connection with a financing, acquisition, investment, our equity incentive plan or otherwise. The number of new shares of our common stock issued in connection with raising additional capital could constitute a material portion of the then outstanding shares of our common stock, which could result in substantial dilution to our existing stockholders and cause the market price of our common stock to decline. Provisions in our corporate charter documents and under Delaware law may prevent or frustrate attempts by our stockholders to change our management and hinder efforts to acquire a controlling interest in us, and the market price of our common stock may be lower as a result. There are provisions in our certificate of incorporation and bylaws that may make it difficult for a third party to acquire, or attempt to acquire, control of our company, even if a change of control was considered favorable by you and other stockholders. For example, our board of directors has the authority to issue up to 10,000,000 shares of preferred stock. The board of directors can fix the price, rights, preferences, privileges, and restrictions of the preferred stock without any further vote or action by our stockholders. The issuance of shares of preferred stock may delay or prevent a change of control transaction. As a result, the market price of our common stock and the voting and other rights of our stockholders may be adversely affected. An issuance of shares of preferred stock may result in the loss of voting control to other stockholders. Our charter documents also contain other provisions that could have an anti-takeover effect, including: • • • • • only one of our three classes of directors will be elected each year; stockholders will not be entitled to remove directors other than by a 66 2⁄3% vote and only for cause; stockholders will not be permitted to take actions by written consent; stockholders cannot call a special meeting of stockholders; and stockholders must give advance notice to nominate directors or submit proposals for consideration at stockholder meetings. In addition, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which regulates corporate acquisitions by prohibiting Delaware corporations from engaging in specified business combinations with particular stockholders of those companies. These provisions could discourage potential acquisition proposals and could delay or prevent a change of control transaction. They could also have the effect of discouraging others from making tender offers for our common stock, including transactions that may be in your best interests. These provisions may also prevent changes in our management or limit the price that investors are willing to pay for our stock. 69 Concentration of ownership of our common stock among our existing executive officers, directors and principal stockholders may prevent new investors from influencing significant corporate decisions. Our executive officers, directors and current beneficial owners of 5% or more of our common stock and their respective affiliates beneficially own a significant percentage of our outstanding common stock. As a result, these persons, acting together, would be able to significantly influence all matters requiring stockholder approval, including the election and removal of directors, any merger, consolidation, sale of all or substantially all of our assets, or other significant corporate transactions. Some of these persons or entities may have interests different than yours. For example, because many of these stockholders purchased their shares at prices substantially below the current market price of our common stock and have held their shares for a longer period, they may be more interested in selling our company to an acquirer than other investors, or they may want us to pursue strategies that deviate from the interests of other stockholders. We are an “emerging growth company” and a “smaller reporting company” and, as a result of the reduced disclosure and governance requirements applicable to emerging growth companies and smaller reporting companies, our common stock may be less attractive to investors. We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, and we intend to take advantage of some of the exemptions from reporting requirements that are applicable to other public companies that are not emerging growth companies, including: • • • • not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting; not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements; reduced disclosure obligations regarding executive compensation in our periodic reports, proxy statements and registration statements; and not being required to hold a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our common stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile. We may take advantage of these reporting exemptions until we are no longer an emerging growth company. We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the closing of our initial public offering, (b) in which we have total annual gross revenue of at least $1.07 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non- convertible debt during the prior three-year period. Under Section 107(b) of the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. Even after we no longer qualify as an emerging growth company, we may, under certain circumstances, still qualify as a “smaller reporting company,” which would allow us to take advantage of many of the same exemptions from disclosure requirements, including reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could be impaired. We are subject to the reporting requirements of the Securities Exchange Act of 1934, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and the rules and regulations of the stock market on which our common stock is listed. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. 70 We may identify weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement of our financial statements. Our internal control over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected. If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, or if we are unable to maintain proper and effective internal controls, we may not be able to produce timely and accurate financial statements. If that were to happen, the market price of our stock could decline and we could be subject to sanctions or investigations by the stock exchange on which our common stock is listed, the Securities and Exchange Commission, or the SEC, or other regulatory authorities. We have broad discretion in the use of our cash and cash equivalents. We have broad discretion over the use of our cash and cash equivalents, including the net proceeds from our recent public offerings. You may not agree with our decisions, and our use of these cash and cash equivalents may not yield any return on your investment. We expect to use our existing cash and cash equivalents to advance PB2452, PB1046 and PB6440, fund development of our ELP technology and preclinical programs and for working capital and general corporate purposes. In addition, we may use a portion of our cash and cash equivalents to pursue our strategy to in-license or acquire additional product candidates. Our failure to apply our cash and cash equivalents effectively could compromise our ability to pursue our growth strategy and we might not be able to yield a significant return, if any, on our investment of these cash and cash equivalents. You will not have the opportunity to influence our decisions on how to use these cash and cash equivalents. New or future changes to tax laws could materially adversely affect our company. On December 22, 2017, President Trump signed into law H.R. 1, “An Act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018”, informally titled the Tax Cuts and Jobs Act, or the Tax Act, which significantly revises the United States Internal Revenue Code of 1986, as amended. Future guidance from the United States Internal Revenue Service and other tax authorities with respect to the Tax Act may affect us, and certain aspects of the Tax Act could be repealed or modified in future legislation. Changes in corporate tax rates, the realization of net deferred tax assets relating to our United States operations, the taxation of foreign earnings, and the deductibility of expenses under the Tax Act or future tax reform legislation could have a material impact on the value of our deferred tax assets, could result in significant one-time charges in the current or future taxable years, and could increase our future United States tax expense. The foregoing items, as well as any other future changes in tax laws, could have a material adverse effect on our business, cash flow, financial condition, or results of operations. In addition, it is uncertain if and to what extent various states will conform to the Tax Act or any newly enacted federal tax legislation. Our effective tax rate may fluctuate, and we may incur obligations in tax jurisdictions in excess of accrued amounts. We are subject to taxation in more than one tax jurisdiction. As a result, our effective tax rate is derived from a combination of applicable tax rates in the various places that we operate. In preparing our financial statements, we estimate the amount of tax that will become payable in each of such places. Nevertheless, our effective tax rate may be different than experienced in the past due to numerous factors, including passage of the newly enacted federal income tax law, changes in the mix of our profitability from jurisdiction to jurisdiction, the results of examinations and audits of our tax filings, our inability to secure or sustain acceptable agreements with tax authorities, changes in accounting for income taxes and changes in tax laws. Any of these factors could cause us to experience an effective tax rate significantly different from previous periods or our current expectations and may result in tax obligations in excess of amounts accrued in our financial statements. We might not be able to utilize a significant portion of our net operating loss carryforwards. At December 31, 2019, we had federal and state net operating loss, or NOL, carryforwards of $149.0 million, $153.4 million, respectively. The federal NOLs generated prior to 2018 may be used to offset up to 100% of future taxable income and will begin to expire in 2022, unless previously utilized. These net operating loss carryforwards could expire unused and be unavailable to offset future income tax liabilities. Under the Tax Act, federal net operating losses incurred in 2018 and in future years may be carried forward indefinitely, but the deductibility of such federal net operating losses is limited. It is uncertain how various states will respond to the Tax Act. In addition, under Section 382 of the Internal Revenue Code of 1986, as amended, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation’s ability to use 71 its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income or taxes may be limited. We may experience ownership changes as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. If an ownership change occurs and our ability to use our net operating loss carryforwards is materially limited, it would harm our future operating results by effectively increasing our future tax obligations. Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital appreciation, if any, will be your sole source of gains and you may never receive a return on your investment. You should not rely on an investment in our common stock to provide dividend income. We have not declared or paid cash dividends on our common stock to date. We currently intend to retain our future earnings, if any, to fund the development and growth of our business. In addition, the terms of the SFJ Agreement preclude us from paying dividends, and any existing or future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future. Investors seeking cash dividends should not purchase our common stock. We have begun incurring increased costs and demands upon management as a result of being a public company. As a public company listed in the United States, we are incurring significant additional legal, accounting and other costs, which we anticipate could be between $2.0 million and $3.0 million annually. These additional costs could negatively affect our financial results. In addition, changing laws, regulations and standards relating to corporate governance and public disclosure, including regulations implemented by the SEC and the Nasdaq Stock Market, may increase legal and financial compliance costs and make some activities more time-consuming. These laws, regulations and standards are subject to varying interpretations and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expense and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If notwithstanding our efforts to comply with new laws, regulations and standards, we fail to comply, regulatory authorities may initiate legal proceedings against us and our business may be harmed. Failure to comply with these rules might also make it more difficult for us to obtain some types of insurance, including director and officer liability insurance, and we might be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these events could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, on committees of our board of directors or as members of senior management. Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware and the federal district courts of the United States of America will be the exclusive forums for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees. Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim for breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (3) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws or (4) any action asserting a claim governed by the internal affairs doctrine. Our amended and restated certificate of incorporation further provides that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. These exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. For example, stockholders who do bring a claim in the Court of Chancery could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near the State of Delaware. The Court of Chancery and federal district courts may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. Some companies that adopted a similar federal district court forum selection provision are currently subject to a suit in the Chancery Court of Delaware by stockholders who assert that the provision is not enforceable. If a court were to find either choice of forum provision contained in our amended 72 and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition. Recently, the Court of Chancery of the State of Delaware issued an opinion invalidating the federal district court exclusive forum provision, which decision has been appealed. In light of that recent decision, we will not attempt to enforce this provision of our amended and restated certificate of incorporation, unless the decision is reversed on appeal. As a result, we may incur additional costs associated with resolving disputes that would otherwise be restricted by that provision in other jurisdictions, which could seriously harm our business. However, if the decision is reviewed on appeal and ultimately overturned by the Delaware Supreme Court, we would enforce the federal district court exclusive forum provision. Item 1B. Unresolved Staff Comments. None. Item 2. Properties. We lease 16,000 square feet of research and development and administrative space in Malvern, Pennsylvania, pursuant to a lease agreement that expires in September 2023. We also lease 4,000 square feet of administrative space in San Diego, California, pursuant to a lease agreement that expires in October 2022. We believe that our existing facilities are suitable and adequate to meet our current needs. We intend to add new facilities or expand existing facilities as we add employees, and we believe that suitable additional or substitute space will be available as needed to accommodate any such expansion of our operations. Item 3. Legal Proceedings. We are not subject to any material legal proceedings. From time to time, we may be involved in various claims and legal proceedings relating to claims arising out of our operations. We are not currently a party to any legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. Item 4. Mine Safety Disclosures. Not applicable. 73 Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities. Market Information for Common Stock Our common stock is listed on The Nasdaq Global Market under the symbol “PHAS." PART II Holders of Record As of March 26, 2020, we had 56 holders of record of our common stock, which excludes stockholders whose shares were held in nominee or street name by brokers.

Selected Financial Data. We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information required under this item. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our financial statements and related notes and the related Management’s Discussion and Analysis of Financial Condition and Results of Operations included in this Annual Report on Form 10-K. Overview We are a clinical-stage biopharmaceutical company focused on the development and commercialization of novel therapies for cardiopulmonary diseases, with an initial focus on cardiopulmonary indications. Our lead product candidate, PB2452, is a novel reversal agent for the antiplatelet drug ticagrelor, which we are developing for the reversal of the antiplatelet effects of ticagrelor in patients with uncontrolled major or life- threatening bleeding or requiring urgent surgery or an invasive procedure. Based on feedback from the FDA we intend to seek approval of PB2452 in the United States through an accelerated approval process. In our completed Phase 2a clinical trial of PB2452, we observed immediate and complete reversal of ticagrelor’s antiplatelet activity within five minutes following initiation of infusion and sustained reversal for over 20 hours. We are developing PB2452 with SFJ pursuant to the SFJ Agreement. Under the SFJ Agreement, SFJ has agreed to pay us up to $120.0 million to support the clinical development of PB2452. During the term of the SFJ Agreement, we will 74 have primary responsibility for clinical development and regulatory activities for PB2452 in the United States and the European Union, while SFJ will have primary responsibility for clinical development and regulatory activities for PB2452 in China and Japan and will provide clinical trials operations support in the European Union. The FDA granted Breakthrough Therapy designation for PB2452 in April 2019. The EMA granted PB2452 PRIME designation in February 2020. Based on feedback from the FDA, we intend to submit a BLA for potential accelerated approval based on an interim analysis of the first approximately 100 patients treated in our Phase 3 trial, with approximately 50 patients with uncontrolled major or life-threatening bleeding and approximately 50 patients requiring urgent surgery or an invasive procedure. We recently commenced our pivotal Phase 3 clinical trial. Based on an 18- month estimated enrollment timeline for the first 100 patients in the Phase 3 trial, we are targeting to submit our BLA for PB2452 in the second half of 2022. To support full approval for patients with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure, the FDA recommended enrollment of 200 total patients in the Phase 3 trial. After we submit our BLA with data from the first 100 patients, we intend to complete the Phase 3 trial and establish a post-approval registry in accordance with FDA requirements. The CHMP of the EMA has also generally agreed with our proposed development plan for PB2452. Our second product candidate, PB1046, is a once-weekly fusion protein currently in a Phase 2b clinical trial for the treatment of PAH. PB1046 utilizes our ELP technology, which also serves as an engine for our preclinical pipeline. We have temporarily paused enrollment of new patients in this trial as a precaution to minimize potential exposure of this patient population at high risk of serious illness from COVID-19. However, we have also informed investigators that they may continue dosing PB1046 and performing assessments for current trial participants if they deem it appropriate and such activities are permitted by their respective institutions. Additionally, we continue to identify new trial sites for future initiation. Although we have been targeting to report results from this trial in the fourth quarter of 2020, we believe that the COVID-19 outbreak will temporarily prevent us from being able to initiate new trial sites and enroll new patients, likely delaying our ability to report the results of this trial into 2021. We are also developing our preclinical product candidate, PB6440, for treatment-resistant hypertension. We retain worldwide commercial rights to all of our product candidates. We have a limited operating history. Since our inception in 2002, our operations have focused on developing our clinical and preclinical product candidates and our proprietary ELP technology, organizing and staffing our company, business planning, raising capital, establishing our intellectual property portfolio and conducting clinical trials and preclinical studies. We do not have any product candidates approved for sale and have not generated any revenue from product sales. Since inception, we have financed our operations primarily through the sale of equity and debt securities and our term loans with SVB and WestRiver. In 2018, we received $60.7 million in aggregate net proceeds from our IPO and the sale of Series D convertible preferred stock and $4.0 million in borrowings under our term loan with SVB. In April 2019, we received $46.3 million in net proceeds from an underwritten public offering of our common stock. In May 2019, we received an additional $2.5 million under our term loan with SVB and WestRiver, or our 2019 Loan, and in October 2019, we received an additional $5.0 million under our 2019 Loan. In January 2020, we entered into the SFJ Agreement pursuant to which SFJ has agreed to provide us up to $120.0 million of funding to support the clinical development of PB2452. In March 2020, SFJ paid us an initial $10.0 million. SFJ will pay us an additional $80.0 million through cost reimbursements followed by six equal quarterly payments beginning with the quarter ending September 30, 2020 through the quarter ending December 31, 2021, and up to an additional $30.0 million upon the achievement of specified clinical development milestones with respect to our ongoing Phase 3 clinical trial of PB2452. Since our inception, we have incurred significant operating losses. Our net loss was $39.2 million for the year ended December 31, 2019. As of December 31, 2019, we had an accumulated deficit of $162.2 million. We expect to continue to incur significant expenses and operating losses for the foreseeable future. We anticipate that our expenses will increase substantially in connection with our ongoing activities, as we: • • • • • • continue our ongoing clinical trials of PB2452 and PB1046, as well as initiate and complete additional clinical trials, as needed; seek to expand our geographical reach through the SFJ Agreement and the corresponding clinical development support fees that we will incur; pursue regulatory approvals for PB2452 as a reversal agent for the antiplatelet drug ticagrelor and PB1046 for the treatment of PAH; develop PB6440 for treatment-resistant hypertension; seek to discover and develop additional clinical and preclinical product candidates; scale up our clinical and regulatory capabilities; 75 • • • • • • establish a commercialization infrastructure and scale up external manufacturing and distribution capabilities to commercialize any product candidates for which we may obtain regulatory approval, including PB2452 and PB1046; adapt our regulatory compliance efforts to incorporate requirements applicable to marketed products; maintain, expand and protect our intellectual property portfolio; hire additional clinical, manufacturing and scientific personnel; add operational, financial and management information systems and personnel, including personnel to support our product development and planned future commercialization efforts; and incur additional legal, accounting and other expenses in operating as a public company. Recent Developments Co-Development Agreement with SFJ In January 2020, we entered into the SFJ Agreement with SFJ, pursuant to which SFJ has agreed to pay us up to $120.0 million to support the clinical development of PB2452. In March 2020, SFJ paid us an initial $10.0 million. SFJ will fund $80.0 million of development expenses through the end of 2021 and up to an additional $30.0 million based on us meeting specific, pre-defined clinical milestones for PB2452. During the term of the SFJ Agreement, we will have primary responsibility for clinical development and regulatory activities for PB2452 in the United States and the European Union, while SFJ will have primary responsibility for clinical development and regulatory activities for PB2452 in China and Japan and will provide clinical trials operations support in the European Union. Refer to "Item 1. Business" under the subheading Business - License, Co-Development and Other Agreements - Co-Development Agreement for PB2452 with SFJ Pharmaceuticals in this annual report. PB6440 Asset Purchase Agreement In January 2020, we entered into an asset purchase agreement with Viamet and Selenity to acquire all of the assets and intellectual property rights related to PB6440, a novel oral aldosterone synthase inhibitor, which we plan to develop for treatment-resistant hypertension. Refer to "Item 1. Business" under the subheading Business - License, Co-Development and Other Agreements - Viamet Asset Purchase Agreement in this annual report. Commencement of Pivotal Phase 3 Clinical Trial for PB2452 We recently commenced our pivotal Phase 3 clinical trial. Based on feedback from the FDA, we intend to submit a BLA for potential accelerated approval based on an interim analysis of the first approximately 100 patients treated in our Phase 3 trial, with approximately 50 patients with uncontrolled major or life-threatening bleeding and approximately 50 patients requiring urgent surgery or an invasive procedure. After we submit our BLA with data from the first 100 patients, we intend to complete the Phase 3 trial and establish a post-approval registry in accordance with FDA requirements. FINANCIAL OVERVIEW Components of Operating Results Revenue Grant Revenue Grant revenue is derived from government grants that support our efforts on specific research projects. We recognize grant revenue when there is reasonable assurance of compliance with the conditions of the grant and reasonable assurance that the grant revenue will be received. 76 Revenue Under Collaborative Agreement Revenue under collaborative agreement is derived from an agreement with our collaboration partner, ImmunoForge Co., Ltd., or ImmunoForge. We have granted ImmunoForge a license to develop certain compound indications in exchange for an upfront license payment and event- based payments subject to ImmunoForge’s achievement of specified development, regulatory and sales-based milestones. In addition, we are entitled to royalties if products under the collaboration are commercialized. We recognize revenue for upfront amounts when the license is transferred to ImmunoForge. Development milestones and other fees are recognized as revenue when it is probable that the amount will not result in a significant reversal of revenue in the future. Sales-based milestones and royalties cannot be recognized until the underlying sales occur. Research and Development Expense Research and development expense consists of expenses incurred in connection with the discovery and development of our product candidates. We expense research and development costs as incurred. These expenses include: • • • • • • • expenses incurred under agreements with contract research organizations, or CROs, as well as investigative sites and consultants that conduct our clinical trials and preclinical studies; manufacturing and supply scale-up expenses and the cost of acquiring and manufacturing preclinical and clinical trial supply and potential commercial supply, including manufacturing validation batches; clinical development support fees that we incur related to the SFJ Agreement; outsourced professional scientific development services; employee-related expenses, which include salaries, benefits and stock-based compensation; expenses relating to regulatory activities; and laboratory materials and supplies used to support our research activities. Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect our research and development expense to increase significantly over the next several years as we increase personnel costs, including stock-based compensation, conduct our later-stage clinical trials for PB2452 and PB1046, develop PB6440, conduct other preclinical studies and clinical trials and prepare regulatory filings and, if we receive regulatory approval for one or more product candidates, prepare for commercialization efforts. The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the remainder of the development of our product candidates, or when, if ever, material net cash inflows may commence from those candidates. This uncertainty is due to the numerous risks and uncertainties associated with the duration and cost of clinical trials, which vary significantly over the life of a project as a result of many factors, including: • • • • • • • • • delays in regulators or institutional review boards authorizing us or our investigators to commence our clinical trials or in our ability to negotiate agreements with clinical trial sites or contract research organizations; our ability to secure adequate supply of product candidates for our trials; the number of clinical sites included in the trials; the length of time required to enroll suitable patients; the number of patients that ultimately participate in the trials; the number of doses patients receive; any side effects associated with our product candidates; the duration of patient follow-up; and the results of our clinical trials. Our expenditures are subject to additional uncertainties, including the terms and timing of regulatory approvals, and the expense of filing, prosecuting, defending and enforcing any patent claims or other intellectual property rights. We may 77 never succeed in achieving regulatory approval for our product candidates. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of our product candidates. A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or other regulatory authorities were to require us to conduct clinical trials beyond those that we currently anticipate, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development. Product commercialization will take several years and millions of dollars in development costs. General and Administrative Expense General and administrative expense consists principally of salaries and related costs for personnel in executive and administrative functions, including stock-based compensation, travel expenses and recruiting expenses. Other general and administrative expense includes professional fees for legal, accounting and tax-related services and insurance costs. We anticipate that our general and administrative expense will increase as we continue to operate as a public reporting company and continue to develop PB2452, PB1046, PB6440 and our future product candidates. We believe that these increases likely will include increased costs for director and officer liability insurance, costs related to the hiring of additional personnel and increased fees for outside consultants, lawyers and accountants. We also expect to incur increased costs to comply with corporate governance, internal controls, investor relations, disclosure and similar requirements applicable to public reporting companies. Interest Expense Interest expense consists of interest expense on our convertible promissory notes and term loan. Following the conversion of the convertible promissory notes into shares of redeemable convertible Series D preferred stock in August 2018, we no longer recognize interest on the convertible promissory notes. We recognize interest on our term loan with SVB and WestRiver. Change in Fair Value of Warrant and Derivative Liabilities Change in fair value of warrant and derivative liabilities reflects the revaluation at each reporting date of our redeemable convertible preferred stock warrants and the conversion option on our convertible promissory notes, respectively. Following the conversion of our convertible promissory notes to preferred stock in August 2018, the conversion of all outstanding shares of our preferred stock into common stock, and the corresponding conversion of all outstanding preferred stock warrants into common stock warrants, in connection with the closing of our IPO in October 2018, we no longer remeasure the warrant liability or derivative liability for periods following the closing of the IPO. License, Co-Development and Other Agreements MedImmune Limited License Agreement In November 2017, we entered into the MedImmune License with MedImmune. Pursuant to the MedImmune License, MedImmune granted us an exclusive, worldwide license under certain patent rights owned or controlled by MedImmune to develop and commercialize the MedImmune Licensed Products, for the treatment, palliation, diagnosis or prevention of any human disorder or condition. Under the MedImmune License, we paid MedImmune an upfront fee of $0.1 million. We are also required to pay MedImmune: quarterly fees relating to technical services provided by MedImmune; up to $18.0 million in clinical and regulatory milestone fees, $1.0 million of which was incurred in the second quarter of 2019; up to $50.0 million in commercial milestone fees; and mid-single digit to low-teen royalty percentages on net sales of MedImmune Licensed Products, subject to reduction in specified circumstances. In addition, the MedImmune License offers an option for third-party product storage costs. From the inception of the MedImmune License through December 31, 2019, we have incurred costs of $1.6 million under the MedImmune License. Co-Development Agreement with SFJ Pharmaceuticals In January 2020, we entered into the SFJ Agreement, pursuant to which SFJ will provide us funding to support the global development of PB2452 as a reversal agent for the antiplatelet drug ticagrelor in patients with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure. Under the SFJ Agreement, SFJ has agreed to pay us up to $120.0 million to support the clinical development of PB2452. SFJ paid us an initial $10.0 million in March 2020 after we obtained the consent of Silicon Valley Bank, or SVB, to grant SFJ a security interest in all of the assets owned or controlled 78 by us that are necessary for the manufacture, use or sale of PB2452. SFJ will pay us an additional $80.0 million through cost reimbursements followed by six equal quarterly payments beginning with the quarter ending September 30, 2020 through the quarter ending December 31, 2021 and up to an additional $30.0 million upon the achievement of specified milestones with respect to our clinical development of PB2452. During the term of the SFJ Agreement, we will have primary responsibility for clinical development and regulatory activities for PB2452 in the United States and the European Union, while SFJ will have primary responsibility for clinical development and regulatory activities for PB2452 in China and Japan and will provide clinical trials operational support in the European Union. Under the terms of the SFJ Agreement, following the FDA approval of a BLA for PB2452, we will pay SFJ an initial payment of $5.0 million and an additional $325.0 million in the aggregate in seven additional annual payments. If the EMA or the national regulatory authority in certain European countries approve a BLA for PB2452, we will pay SFJ an initial payment of $5.0 million and an additional $205.0 million in the aggregate in seven additional annual payments. If either the PMDA of Japan or the NMPA of China approves a marketing application for PB2452, we will pay SFJ an initial payment of $1.0 million and then an additional $59.0 million in the aggregate in eight additional annual payments. Within 120 days following approval of a BLA for PB2452 in one of the jurisdictions described above, we have the right, at our option, to make a one-time cash payment to SFJ to buy out all or a portion of the future unpaid approval payments for such jurisdiction (i.e., the U.S. Approval Payments, EU Approval Payments or Japan/China Approval Payments, as applicable) for a price reflecting a mid-single-digit discount rate. Within 120 days following a change of control of our company, we or our successor have the right, at its option, to make a one-time cash payment to SFJ to buy out all or a portion of the future unpaid approval payments in any of the jurisdictions in which a BLA for PB2452 was approved prior to the change of control for a price reflecting a mid-single-digit discount rate, provided that SFJ has not previously assigned the right to receive such payments to a third party (in which event we or our successor shall not have such right). If following termination of the SFJ Agreement we continue to develop PB2452 and obtain BLA approval in the United States, the European Union, Japan or China, we will make the applicable approval payments for such jurisdiction to SFJ as if the SFJ Agreement had not been terminated, less any payments made upon termination, except that if we terminate the SFJ Agreement for SFJ’s failure to make any payment to us when due, or SFJ terminates the SFJ Agreement due to a material adverse event, as defined in the SFJ Agreement, then our obligation to make such approval payments would be reduced by 50%. Duke License Agreement In October 2006, we entered into the Duke License with Duke, which we most recently amended in April 2019. Pursuant to the Duke License, Duke granted us an exclusive, worldwide license under certain patent rights owned or controlled by Duke, and a non-exclusive, worldwide license under certain know-how of Duke, to develop and commercialize the Duke licensed products relating to ELPs. Under the Duke License, we paid Duke an upfront fee of $37,000, additional fees in connection with amendments to the Duke License of $0.2 million and other additional licensing fees of $0.2 million. In consideration for license rights granted to us, we initially issued Duke 24,493 shares of our common stock. Until we reached a certain stipulated equity milestone, which we reached in October 2007, we were obligated to issue additional shares of common stock to Duke from time to time so that its aggregate ownership represented 7.5% of our issued and outstanding capital stock. We are also required to pay Duke: up to $2.2 million in regulatory and clinical milestone fees; up to $0.4 million in commercial milestone fees; low single-digit royalty percentages on net sales of Duke licensed products, with minimum aggregate royalty payments of $0.2 million payable following our achievement of certain commercial milestones; and up to the greater of $0.3 million or a low double-digit percentage of the fees we receive from a third party in consideration of forming a strategic alliance with respect to certain patent rights covered under the Duke License. We also must pay Duke the first $1.0 million of non-royalty payments we receive from a sublicensee, and thereafter a low double-digit percentage of any additional nonroyalty payments we receive, subject to certain conditions. From the inception of the Duke License through December 31, 2019, we have incurred royalty costs of $0.3 million under the Duke License. We are also required to apply for, prosecute and maintain all United States and foreign patent rights under the Duke License. Wacker License Agreement In April 2019, we entered into a license agreement, or the Wacker License Agreement, with Wacker Biotech GmbH, or Wacker, pursuant to which Wacker granted us an exclusive license under certain of Wacker’s intellectual property rights to use Wacker’s proprietary E. coli strain for the manufacture of PB2452 worldwide outside of specified Asian countries and to commercialize PB2452, if approved, manufactured by us or on our behalf using Wacker’s proprietary E. coli strain throughout the world. We have the right to grant sublicenses under the license, subject to certain conditions as specified in the Wacker License Agreement. Under the terms of the agreement, we are required to pay a fixed, nominal per-unit royalty, which is subject to adjustment, and an annual license fee in a fixed Euro amount in the low to mid six digits. The agreement will be in 79 force for an indefinite period of time, and upon the expiration of our royalty obligations, the license will be considered fully paid and will convert to a non- exclusive license. Either party may terminate the Wacker License Agreement for breach if such breach is not cured within a specified number of days. We incurred $0.2 million in costs under the Wacker License Agreement for the year ended December 31, 2019. Viamet Asset Purchase Agreement In January 2020, we entered into the PB6440 Agreement with Viamet Pharmaceuticals Holdings, LLC and its wholly-owned subsidiary, Selenity Therapeutics (Bermuda), Ltd., or the Sellers, pursuant to which we acquired all of the assets and intellectual property rights related to the Sellers’ proprietary CYP11B2 inhibitor compound, formerly known as SE-6440 or VT-6440, and certain other CYP11B2 inhibitor compounds that are covered by the patent rights acquired by us under the PB6440 Agreement, or together, Compounds. Under the terms of the PB6440 Agreement, we paid the Sellers an upfront fee of $0.1 million upon the closing of the transaction, and we are required to pay the Sellers up to $5.1 million upon the achievement of certain development and intellectual property milestones with respect to certain product candidates that contain a Compound, up to $142.5 million upon the achievement of certain commercial milestones with respect to any approved product that contains a Compound and low- to mid-single digit royalty percentages on the net sales of approved products that contain a Compound, subject to customary reductions and offsets in specified circumstances. We incurred $0.1 million in costs under the PB6440 Agreement for the year ended December 31, 2019. Results of Operations Comparison of the Years Ended December 31, 2019 and 2018 The following table summarizes our results of operations for the years ended December 31, 2019 and 2018 (in thousands): Revenue: Grant revenue Revenue under collaborative agreement Total revenue Operating expenses: Research and development General and administrative Total operating expenses Loss from operations Other income (expense): Interest income Interest expense Foreign exchange loss Change in fair value of warrant liability Change in fair value of derivative liability Total other income (expense) Net loss Revenue Year Ended December 31, 2019 2018 Change $ 1,786 $ 575 2,361 30,911 11,186 42,097 (39,736) 1,582 (1,076) (17) — — 489 668 $ — 668 15,455 4,857 20,312 (19,644) 387 (3,924) — 11 (676) (4,202) $ (39,247) $ (23,846) $ 1,118 575 1,693 15,456 6,329 21,785 (20,092) 1,195 2,848 (17) (11) 676 4,691 (15,401) Grant revenue was $1.8 million for the year ended December 31, 2019, compared to $0.7 million for the year ended December 31, 2018. The increase was due to higher costs that qualified for grant reimbursement under our SBIR grants for the development of PB1046 during the year ended December 31, 2019. We began incurring costs that qualified for grant reimbursement in August 2018 and continued to incur costs throughout 2019. Revenue under collaborative agreement was $0.6 million for the year ended December 31, 2019, compared to zero for the year ended December 31, 2018. The increase of $0.6 million was related to revenue from our agreement with ImmunoForge, which was entered into in 2019. 80 Research and Development Expense Research and development expense was $30.9 million for the year ended December 31, 2019, compared to $15.5 million for the year ended December 31, 2018. The increase of $15.5 million was primarily attributable to increased clinical and drug production activities related to PB2452, increased personnel costs due to additional headcount, increased costs associated with our general research efforts and increased clinical activity related to PB1046. The following table summarizes our research and development expense by functional area for the years ended December 31, 2019 and 2018 (in thousands): Preclinical and clinical development Compensation and related benefits Stock-based compensation Facilities expense Other Total research and development expense Year Ended December 31, 2019 2018 Change 24,368 $ 11,857 $ 4,725 286 766 766 2,789 124 463 222 12,511 1,936 162 303 544 30,911 $ 15,455 $ 15,456 $ $ The following table summarizes our research and development expense by product candidate for the years ended December 31, 2019 and 2018 (in thousands): External research and development expense by program PB2452 PB1046 Unallocated research and development expense: Compensation and stock-based compensation Other research and development Total research and development expense General and Administrative Expense Year Ended December 31, 2019 2018 Change $ 16,660 $ 6,069 5,011 3,171 6,726 $ 4,542 2,913 1,274 $ 30,911 $ 15,455 $ 9,934 1,527 2,098 1,897 15,456 General and administrative expense was $11.2 million for the year ended December 31, 2019, compared to $4.9 million for the year ended December 31, 2018. The increase of $6.3 million was primarily attributable to an increase in professional services related to consulting services and legal services, an increase in personnel expense due to additional headcount and additional expenses associated with being a public company. Interest Income Interest income was $1.6 million for the year ended December 31, 2019, compared to $0.4 million for the year ended December 31, 2018. The increase of $1.2 million was attributable to higher balances of cash and cash equivalents during 2019. Interest Expense Interest expense was $1.1 million for the year ended December 31, 2019, compared to $3.9 million for the year ended December 31, 2018. Interest expense for the year ended December 31, 2019 was attributable to interest on the 2019 Loan. Interest expense for the year ended December 31, 2018 was primarily attributable to interest from borrowings pursuant to our convertible promissory notes, which were outstanding during 2018. These notes were converted into shares of redeemable convertible Series D stock in August 2018. Change in Fair Value of Derivative Liability 81 Change in fair value of derivative liability resulted in no expense for the year ended December 31, 2019, compared to $0.7 million of expense for the year ended December 31, 2018. The conversion option related to our convertible promissory notes was subject to remeasurement at each reporting period, with changes in fair value recorded in the statement of operations. The convertible promissory notes converted into redeemable convertible preferred stock in August 2018 upon the sale of the Series D redeemable convertible preferred stock and, accordingly, we no longer remeasure the fair value of the derivative liability. Liquidity and Capital Resources Since our inception, we have not generated any revenue from product sales and have incurred net losses and negative cash flows from our operations. We have financed our operations since our inception primarily through public offerings of our common stock, private placements of convertible debt and convertible preferred stock and borrowings under our term loans. In future periods, we expect to receive up to $120.0 million from the SFJ Agreement. In October 2017, we entered into a loan and security agreement, or the SVB Loan, with SVB, which provided that we could borrow up to $7.5 million. In August 2018, we received $17.7 million in net proceeds from the sale of our Series D redeemable convertible preferred stock. Concurrent with this financing, all of our outstanding convertible promissory notes, and accrued interest thereon, were converted into 2.1 million shares of Series D redeemable convertible preferred stock. In October 2018, we completed our IPO of our common stock, which resulted in the issuance and sale of 9.9 million shares of common stock at a public offering price of $5.00 per share, generating net proceeds of approximately $43.0 million after deducting underwriting discounts and commissions and other offering costs. Upon closing of the IPO, all outstanding shares of our redeemable convertible preferred stock were converted into an aggregate of 13.2 million shares of common stock. In March 2019, we entered into the 2019 Loan with SVB and WestRiver, pursuant to which we could borrow up to $15.0 million, issuable in three separate tranches. As of December 31, 2019, we had drawn on all three tranches under the 2019 Loan in the amounts of $7.5 million, $2.5 million and $5.0 million. In April 2019, we completed an underwritten public offering of our common stock, which resulted in the issuance and sale of an aggregate of 4,124,475 shares of common stock at a public offering price of $12.00 per share, generating net proceeds of $46.3 million after deducting underwriting discounts and commissions and other offering costs. In December 2019, we filed a shelf registration statement on Form S-3, or the 2019 Shelf Registration Statement, which became effective in January 2020. The 2019 Shelf Registration Statement permits: (i) the offering, issuance and sale by us of up to a maximum aggregate offering price of $200.0 million of common stock, preferred stock, debt securities and warrants in one or more offerings and in any combination; and (ii) the offering, issuance and sale by us of up to a maximum aggregate offering price of $60.0 million of our common stock that may be issued and sold under an “at-the- market” sales agreement, or ATM, with Citigroup Global Markets Inc. and William Blair & Company, L.L.C. No securities have been sold under the 2019 Shelf Registration Statement. In January 2020, we entered into the SFJ Agreement, pursuant to which SFJ agreed to provide funding to support the development of PB2452 as a reversal agent for the antiplatelet drug ticagrelor. Pursuant to the SFJ Agreement, SFJ has agreed to pay us up to $120.0 million, including an initial payment of $10.0 million paid in March 2020, an additional $80.0 million through cost reimbursements followed by six equal quarterly payments beginning with the quarter ending September 30, 2020 through the quarter ending December 31, 2021 and up to an additional $30.0 million upon the achievement of specific clinical development milestones with respect to our ongoing Phase 3 clinical trial of PB2452. As of December 31, 2019, we had cash and cash equivalents of $74.0 million. The following table summarizes our cash flows for each of the periods set forth below (in thousands): Net cash used in operating activities Net cash used in investing activities Net cash provided by financing activities Net increase in cash and cash equivalents 82 Year Ended December 31, 2019 2018 $ $ (39,594) $ (960) 53,528 12,974 $ (17,053) (119) 64,797 47,625 Operating Activities Net cash used in operating activities was $39.6 million during the year ended December 31, 2019. The use of cash primarily related to our net loss of $39.2 million, adjusted for non-cash charges primarily related to $1.4 million in stock-based compensation expense, $0.5 million for non-cash interest expense and a $2.4 million change in our operating assets and liabilities. The change in our operating assets and liabilities was principally due to a $2.0 million increase in prepaid expense and other assets and an increase in other receivables of $1.0 million, partially offset by a $0.8 million increase in accounts payable, all as a result of increased clinical activities for our ongoing clinical trials of PB2452 and PB1046. Net cash used in operating activities was $17.1 million during the year ended December 31, 2018. The use of cash primarily related to our net loss of $23.8 million, adjusted for non-cash charges primarily related to $3.7 million for non-cash interest expense, $0.7 million for the change in the fair value of the derivative liability and a $2.0 million change in our operating assets and liabilities. The change in our operating assets and liabilities was principally due to a $3.3 million increase in accounts payable and accrued expenses, partially offset by a $1.0 million increase in prepaid expenses, all as a result of increased clinical activities for our ongoing clinical trials of PB2452 and PB1046. Investing Activities Net cash used in investing activities was $1.0 million for the purchase of property and equipment during the year ended December 31, 2019. Net cash used in investing activities was $0.1 million for the purchase of property and equipment during the year ended December 31, 2018. Financing Activities Net cash provided by financing activities was $53.5 million during the year ended December 31, 2019, due primarily to the receipt of $46.3 million in net proceeds from the April 2019 underwritten public offering and borrowings of $8.1 million on the 2019 Loan, partially offset by $0.9 million for partial repayment of the SVB Loan. Net cash provided by financing activities was $64.8 million during the year ended December 31, 2018, consisting primarily of $43.0 million in net proceeds from our initial public offering, $17.7 million from the issuance of the Series D redeemable convertible preferred stock and $4.0 million in proceeds from the SVB Loan. Funding Requirements To date, we have not generated any revenues from the commercial sale of approved drug products, and we do not expect to generate substantial revenue for at least the next several years. If we fail to complete the development of our product candidates in a timely manner or fail to obtain their regulatory approval, our ability to generate future revenue will be compromised. We do not know when, or if, we will generate any revenue from our product candidates, and we do not expect to generate significant revenue unless and until we obtain regulatory approval of, and commercialize, our product candidates. We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the research and development of, continue or initiate clinical trials of and seek marketing approval for our product candidates. In addition, if we obtain approval for any of our product candidates, we expect to incur significant commercialization expenses related to sales, marketing, manufacturing and distribution. We anticipate that we will need substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts. We believe that our existing cash and cash equivalents as of December 31, 2019, in addition to the $10.0 million received in March 2020 and the $80.0 million in anticipated proceeds that we will receive pursuant to the SFJ Agreement, will be sufficient to fund our operating expenses and capital requirements into the second half of 2021. We intend to devote our existing cash and cash equivalents to advance our clinical and preclinical development programs. We have based our estimates on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development and commercialization of product candidates, we are unable to estimate the amounts of increased capital outlays and operating expenditures necessary to complete the development of product candidates. Our future capital requirements will depend on many factors, including: • • the progress and results of our ongoing and planned future clinical trials of PB2452, PB1046, PB6440 and our other preclinical programs; the timing and amount of payments we receive under the SFJ Agreement; 83 • • • • • • • • • the scope, progress, results and costs of preclinical development, laboratory testing and clinical trials for any future product candidates we may decide to pursue; the extent to which we develop, in-license or acquire other product candidates and technologies; the number and development requirements of other product candidates that we may pursue; the costs, timing and outcome of regulatory review of our product candidates; the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our product candidates for which we receive marketing approval; the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval; our ability to establish collaborations to commercialize PB1046 in the United States; our ability to establish collaborations to commercialize PB2452, PB1046 or any of our other product candidates outside of the United States; and the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims. Identifying potential product candidates and conducting preclinical studies and clinical trials is a time-consuming, expensive and uncertain process that takes many years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of product candidates that we do not expect to be commercially available in the near term, if at all. Our future commercial revenue, if any, will be derived from sales of products that we do not expect to be commercially available for several years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the terms of these equity securities or this debt may restrict our ability to operate. Any future debt financing and equity financing, if available, may involve agreements that include covenants limiting and restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, entering into profit-sharing or other arrangements or declaring dividends. If we raise additional funds through government or private grants, collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. Further, our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-19 pandemic. Off-Balance Sheet Arrangements We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined in the SEC rules and regulations. Critical Accounting Policies and Significant Judgments and Estimates Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with United States generally accepted accounting policies, or GAAP. The preparation of these financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the dates of the balance sheets and the reported amounts of expenses during the reporting periods. In accordance with GAAP, we evaluate our estimates and judgments on an ongoing basis. Significant estimates include assumptions we have used in the determination of accrued research and development costs. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. 84 We believe the following accounting policies are the most critical to the judgments and estimates used in the preparation of our financial statements. See Note 2 to the financial statements appearing elsewhere in this Annual Report for a discussion of our significant accounting policies. Accrued Research and Development Expense The majority of our operating expenses to date have been incurred in research and development activities. As part of the process of preparing our financial statements, we are required to estimate expenses resulting from obligations under contracts with vendors, consultants and research organizations, in connection with conducting clinical and preclinical activities. The financial terms of these contracts are subject to negotiations which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided under such contracts. We reflect preclinical study and clinical trial expenses in our financial statements by matching those expenses with the period in which services and efforts are expended. We account for these expenses according to the progress of the preclinical study or clinical trial as measured by the timing of various aspects of the preclinical study or clinical trial, or related activities. Our accrual estimates are determined through review of the underlying contracts along with preparation of financial models taking into account discussions with research and other key personnel as to the progress of preclinical studies or clinical trials, or other services being conducted. During the course of a preclinical study or clinical trial, we will adjust the rate of expense recognition if actual results differ from our original estimates. Recent Accounting Pronouncements See Note 2 to the financial statements appearing elsewhere in this Annual Report for information concerning recent accounting pronouncements. JOBS Act Transition Period In April 2012, the JOBS Act was enacted. Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies. We are in the process of evaluating the benefits of relying on other exemptions and reduced reporting requirements under the JOBS Act. Subject to certain conditions, as an emerging growth company, we may rely on certain of these exemptions, including without limitation, (i) not providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (ii) not complying with any requirement that may be adopted by the Public Company Accounting Oversight Board. We will remain an emerging growth company until the earliest to occur of (1) the last day of the fiscal year (a) ending December 31, 2023, which is the end of the fiscal year following the fifth anniversary of the completion our initial public offering, (b) in which we have total annual gross revenues of at least $1.07 billion or (c) in which we are deemed to be a “large accelerated filer” under the rules of the SEC, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. We are a “smaller reporting company” (and may continue to qualify as such even after we no longer qualify as an emerging growth company) and accordingly may provide less public disclosure than larger public companies, including the inclusion of only two years of audited financial statements and only two years of related selected financial data and management’s discussion and analysis of financial condition and results of operations disclosure. As a result, the information that we provide to our stockholders may be different than what they might receive from other public reporting companies in which they hold equity interests. Effect of Inflation Inflation did not have a significant impact on our net sales, revenues or income from continuing operations in 2019 or 2018. Item 7A. Quantitative and Qualitative Disclosures About Market Risk. 85 We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information required under this item. Item 8. Financial Statements and Supplementary Data. The information required by this Item 8 is set forth in our financial statements included in Part IV, Item 15 of this Annual Report on Form 10- K. Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure. None. Item 9A. Controls and Procedures. Disclosure Controls and Procedures We maintain “disclosure controls and procedures,” as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our principal executive and our principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. With respect to the year ended December 31, 2019, under the supervision and with the participation of our management, we conducted an evaluation of the effectiveness of the design and operations of our disclosure controls and procedures. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of December 31, 2019 to provide reasonable assurance that the information required to be disclosed by us in this Annual Report was (a) reported within the time periods specified by SEC rules and regulations and (b) communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding any required disclosure. Management's Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the company's principal executive and principal financial officers and effected by the company's board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that: • • • Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company; Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2019. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013 framework) (COSO). Based on its assessment, management believes that, as of December 31, 2019, our internal control over financial reporting is effective at the reasonable assurance level. This Annual Report does not include an attestation report of our independent registered public accounting firm as allowed by the SEC's transition period for emerging growth companies. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to 86 the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Changes in Internal Control over Financial Reporting There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the fiscal year ended December 31, 2019 which have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

(the Company) as of December 31, 2019 and 2018, the related statements of operations, redeemable convertible preferred stock and stockholders’ equity (deficit), and cash flows for the years then ended, and the related notes (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the years then ended, in conformity with U.S. generally accepted accounting principles. Change in Accounting Principle As discussed in Note 2 to the financial statements, the Company has changed its method of accounting for leases as of January 1, 2019 due to the adoption of Accounting Standards Update 2016-02, Leases, and related amendments. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. /s/ KPMG LLP We have served as the Company’s auditor since 2010.

NOTES TO THE FINANCIAL STATEMENTS 1. Organization and Description of Business Description of Business PhaseBio Pharmaceuticals, Inc. (the “Company”) was incorporated as a Delaware corporation on January 10, 2002. The Company is a clinical-stage biopharmaceutical company focused on the development and commercialization of novel therapies for cardiopulmonary diseases. The Company’s lead product candidate, PB2452, is a novel reversal agent for the antiplatelet drug ticagrelor, which the Company is developing for the reversal of the antiplatelet effects of ticagrelor in patients with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure. The Company’s second product candidate, PB1046, is a once-weekly fusion protein currently in a Phase 2b clinical trial for the treatment of pulmonary arterial hypertension. PB1046 utilizes the Company’s proprietary half-life extending elastin-like polypeptide technology, which also serves as the engine for future product pipeline candidates. Liquidity The Company has experienced net losses and negative cash flows from operations since its inception and, as of December 31, 2019, had an accumulated deficit of $162.2 million. The Company expects to continue to incur net losses for at least the next several years. As of December 31, 2019, the Company had cash and cash equivalents of $74.0 million and working capital of $70.3 million. In January 2020, the Company entered into a co- development agreement ("SFJ Agreement") with SFJ Pharmaceuticals X, Ltd., an SFJ Pharmaceuticals Group company ("SFJ") pursuant to which SFJ will provide funding and operational support for the clinical development of PB2452. Management believes that its existing cash and cash equivalents as of December 31, 2019, in addition to the $10.0 million received in March 2020 and the $80.0 million in anticipated proceeds that the Company will receive pursuant to the SFJ Agreement, will be sufficient to fund operating expenses and capital requirements into the second half of 2021. The Company currently has an effective shelf registration statement on Form S-3 ("2019 Shelf Registration Statement") on file with the Securities and Exchange Commission ("SEC"), which expires January 2023. The 2019 Shelf Registration Statement currently permits the offering, issuance and sale by the Company of up to an aggregate offering price of $200.0 million of common stock, preferred stock, debt securities and warrants in one or more offerings and in any combination, of which $60.0 million may be offered, issued and sold in "at-the-market" sales pursuant to an equity distribution agreement with Citigroup Global Markets Inc. and William Blair & Company, L.L.C ("Equity Distribution Agreement"). No securities have been sold under the 2019 Shelf Registration Statement and no shares have been sold pursuant to the Equity Distribution Agreement. Basis of Presentation The accompanying financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and the rules and regulations of the SEC. Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) promulgated by the Financial Accounting Standards Board (“FASB”). The Company manages its operations as a single reportable segment for the purposes of assessing performance and making operating decisions. 2. Significant Accounting Policies Use of Estimates The preparation of the Company’s financial statements requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in the Company’s financial statements and accompanying notes. The most significant estimates in the Company’s financial statements relate to the valuation of redeemable convertible preferred stock warrants prior to the Initial Public Offering ("IPO"), the conversion option on the convertible notes and clinical trial accruals. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results could differ materially from those estimates and assumptions. Concentrations of Credit Risk F-7 PHASEBIO PHARMACEUTICALS, INC. NOTES TO THE FINANCIAL STATEMENTS Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains certain deposits in federally insured financial institutions in excess of federally insured limits. The Company could experience losses on the money market funds in the future. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity from the date of purchase of three months or less to be cash equivalents. Cash and cash equivalents include cash in readily available checking and money market accounts. Restricted Cash The Company had restricted cash of $20,000 as of December 31, 2018, which was held in a certificate of deposit at the Company’s bank to secure the Company’s corporate credit card. The restriction was removed in June 2019. Fair Value of Financial Instruments The carrying amounts of other receivables, prepaid expenses and other assets, accounts payable and accrued expenses and other current liabilities are reasonable estimates of their fair value because of the short maturity of these items. Based on the borrowing rates currently available to the Company for loans with similar terms, the Company believes the fair values of the term loan and operating lease liabilities and corresponding right-of-use assets approximate their respective carrying values. Property and Equipment Property and equipment are recorded at cost and depreciated over the estimated useful lives of the assets (three to five years) using the straight-line method. Leasehold improvements are amortized over the shorter of their estimated useful lives or the lease term. Leases At lease commencement, the Company records a lease liability based on the present value of lease payments over the expected lease term including any options to extend the lease that the Company is reasonably certain to exercise. The Company calculates the present value of lease payments using an incremental borrowing rate as the Company's leases do not provide an implicit interest rate. The Company's incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. At the lease commencement date, the Company records a corresponding right-of-use lease asset based on the lease liability, adjusted for any lease incentives received and any initial direct costs paid to the lessor prior to the lease commencement date. The Company may enter into leases with an initial term of 12 months or less ("Short-Term Leases"). For any Short-Term Leases, the Company records the rent expense on a straight-line basis and does not record the leases on the balance sheet. The Company had no Short-Term Leases as of December 31, 2019 and 2018. After lease commencement, the Company measures its leases as follows: (i) the lease liability based on the present value of the remaining lease payments using the discount rate determined at lease commencement and (ii) the right-of-use lease asset based on the remeasured lease liability, adjusted for any unamortized lease incentives received, any unamortized initial direct costs and the cumulative difference between rent expense and amounts paid under the lease agreement. Any lease incentives received and any initial direct costs are amortized on a straight-line basis over the expected lease term. Rent expense is recorded on a straight-line basis over the expected lease term. Long-Lived Assets The Company regularly reviews the carrying value and estimated lives of all of its long-lived assets, including property and equipment and right-of-use assets to determine whether indicators of impairment may exist which warrant adjustments to carrying values or estimated useful lives. The determinants used for this evaluation include management’s estimate of the asset’s ability to generate net positive cash flow in future periods as well as the strategic significance of the assets to the Company’s business objectives. Should an impairment exist, the impairment loss would be measured based on the extent that the estimated fair value is less than its carrying value. The Company did not recognize any impairment losses in the years ended December 31, 2019 and 2018. F-8 PHASEBIO PHARMACEUTICALS, INC. NOTES TO THE FINANCIAL STATEMENTS Preferred Stock Warrant Liability The Company previously issued freestanding warrants to purchase shares of its redeemable convertible preferred stock. Since the underlying redeemable convertible preferred stock was classified outside of permanent equity, those warrants were classified as liabilities in the accompanying balance sheet. Warrants classified as liabilities were recorded at their estimated fair value on the date of issuance and were revalued at each subsequent balance sheet date, with fair value changes recognized as increases or reductions to other income (expense) in the accompanying statements of operations. The Company estimated the fair value of these warrants using the Black-Scholes option-pricing model. In connection with the Company’s IPO in October 2018, all warrants were either exercised or converted into warrants to purchase common stock, at which time the liability was reclassified to stockholders’ equity. Preclinical and Clinical Trial Accruals The Company accrues and expenses amounts incurred in connection with preclinical studies and clinical trial activities performed by third parties based upon estimates of the proportion of work completed over the life of the individual trial and subject enrollment rates in accordance with agreements with clinical research organizations, contract manufacturing organizations and clinical trial sites. The Company determines the estimates by reviewing contracts, vendor agreements and purchase orders, and through discussions with internal clinical personnel and external service providers as to the progress or stage of completion of trials or services and the agreed-upon fee to be paid for such services. However, actual costs and timing of clinical trials are highly uncertain, subject to risks and may change depending upon a number of factors, including the Company’s clinical development plan. Management makes estimates of the Company’s accrued expenses as of each balance sheet date in the Company’s financial statements based on facts and circumstances known to the Company at that time. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company will adjust the accrual accordingly. Nonrefundable advance payments for goods and services, including fees for process development or manufacturing and distribution of clinical supplies that will be used in future research and development activities, are deferred and recognized as expense in the period that the related goods are consumed or services are performed. Research and Development Expense Research and development costs are expensed as incurred. Stock-Based Compensation The Company measures and recognizes compensation expense for all stock-based compensation based on the estimated fair value at the date of grant. Currently, the Company’s stock-based awards consist only of stock options; however, future grants under the Company’s equity compensation plan may also consist of shares of restricted stock, restricted stock units, stock appreciation rights, performance awards and performance units. The Company also maintains an employee stock purchase program under which it may issue shares. The Company estimates the fair value of stock options using the Black-Scholes option-pricing model, which requires the use of estimates. The Company recognizes stock-based compensation cost for ratably vesting stock options on a straight-line basis over the requisite service period of the award and records forfeitures in the period in which they occur. The Black-Scholes option-pricing model requires the input of subjective assumptions, including the risk-free interest rate, the fair value of the underlying common stock (for option grants prior to the IPO), the expected dividend yield of the Company’s common stock, the expected volatility of the price of the Company’s common stock, and the expected term of the option. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, the Company’s stock-based compensation expense could be materially different in the future. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. F-9 PHASEBIO PHARMACEUTICALS, INC. NOTES TO THE FINANCIAL STATEMENTS The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company records uncertain tax positions on the basis of a two-step process whereby (1) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely- than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits, if any, within income tax expense, and any accrued interest and penalties are included within the related tax liability line. Grant Revenue Grant revenue is derived from government grants that support the Company’s efforts on specific research projects. The Company has determined that the government agencies providing grants to the Company are not customers. The Company recognizes grant revenue when there is reasonable assurance of compliance with the conditions of the grant and reasonable assurance that the grant revenue will be received. Revenue Under Collaborative Agreement The Company generates revenues from payments received under a collaborative agreement. Under such collaboration agreements, the Company recognizes revenue when it transfers promised goods or services to partners in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To determine revenue recognition for contracts with partners, the Company performs the following five steps: (i) identifies the promised goods or services in the contract; (ii) identifies the performance obligations in the contract, including whether they are distinct in the context of the contract; (iii) determines the transaction price, including the constraint on variable consideration; (iv) allocates the transaction price to the performance obligations in the contract; and (v) recognizes revenue when (or as) the Company satisfies the performance obligations. For revenue from such collaborative agreements, the Company generally collects an upfront license payment from the collaboration partner and is also entitled to receive event-based payments subject to the collaboration partner's achievement of specified development, regulatory and sales-based milestones. In addition, the Company is generally entitled to royalties if products under the collaboration are commercialized. Although such agreements are in form structured as collaborative agreements, for accounting purposes they represent contracts with partners that are not subject to accounting literature on collaborative arrangements. If the Company grants to collaboration partners a license to the Company’s intellectual property, the Company does not develop assets jointly with the collaboration partner and does not share in significant risks of their development or commercialization activities. Transaction price for a contract represents the amount to which the Company is entitled in exchange for providing goods and services to the partner. Transaction price does not include amounts subject to uncertainties unless it is probable that there will be no significant reversal of revenue when the uncertainty is resolved. Apart from the upfront license payment, all other fees the Company may earn under such collaborative agreements are subject to significant uncertainties of product development. Achievement of many of the event-based development and regulatory milestones may not be probable until such milestones are actually achieved. This generally relates to milestones such as obtaining marketing authorization approvals and successful completion of clinical trials. With respect to other development milestones, e.g. dosing of a first patient in a clinical trial, achievement could be considered probable prior to its actual occurrence, based on the progress towards commencement of the trial. The Company does not include any amounts subject to uncertainties into the transaction price until it is probable that the amount will not result in a significant reversal of revenue in the future. At the end of each reporting period, the Company re-evaluates the probability of achievement of such milestones and any related constraint, and if necessary, adjusts the estimate of the overall transaction price. Because such agreements generally only have one type of performance obligation, a license, which is generally all transferred at the same time as agreement inception, allocation of the transaction price among multiple performance obligations is not required. F-10 PHASEBIO PHARMACEUTICALS, INC. NOTES TO THE FINANCIAL STATEMENTS Upfront amounts allocated to licenses are recognized as revenue when the licenses are transferred to the collaboration partners. Development milestones and other fees are recognized in revenue when their occurrence becomes probable. Net Loss Per Share Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and common share equivalents outstanding for the period. Common stock equivalents are only included when their effect is dilutive. The Company’s potentially dilutive securities, which include redeemable convertible preferred stock, warrants and outstanding stock options under the Company’s stock option plan, have been excluded from the computation of diluted net loss per share as they would be anti-dilutive. For all periods presented, there is no difference in the number of shares used to compute basic and diluted shares outstanding due to the Company’s net loss position. The following table sets forth the outstanding potentially dilutive securities that have been excluded in the calculation of diluted net loss per share because their inclusion would be anti-dilutive. Common stock options Warrants to purchase common stock Total Recent Accounting Pronouncements As of December 31, 2019 2,577,718 149,595 2,727,313 2018 1,545,403 75,597 1,621,000 In February 2016, the FASB issued ASU 2016-02, Leases. This update amended the current accounting guidance for lease transactions. Under the new guidance, a lessee is required to recognize both assets and liabilities for any leases with terms in excess of twelve months. Additionally, certain qualitative and quantitative disclosures are required in the financial statements. The Company adopted ASU 2016-02 in the first quarter of 2019 using a modified retrospective transition method as of the effective date as permitted by the amendments in ASU 2018-11. As a result, the Company was not required to adjust comparative prior-period financial information for the effects of the standard or make the new required lease disclosures for periods before the date of adoption. The Company elected to adopt the package of transition practical expedients and, therefore, did not reassess (1) whether existing or expired contracts contain a lease, (2) lease classification for existing or expired leases or (3) the accounting for initial direct costs that were previously capitalized. The Company did not elect the practical expedient to use hindsight for leases existing at the adoption date. Further, the Company does not expect the amendments in ASU 2018-01, Land Easement Practical Expedient to have an effect on its financial statements because the Company does not enter into land easement arrangements. The adoption of the new leasing standards did not affect retained earnings and other components of equity as of December 31, 2018. Upon adoption in the first quarter of 2019, the Company recorded right-of-use assets and corresponding lease liabilities of $2.0 million. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement - Disclosure Framework (Topic 820): Changes to the Disclosure Requirements for Fair Value Measurement. The updated guidance improves the disclosure requirements on fair value measurements. The updated guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for any removed or modified disclosures. The Company is currently assessing the timing and impact of adopting the updated provisions. 3. Fair Value Measurement Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. The Company classifies fair value measurements in one of the following three categories for disclosure purposes: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Inputs other than Level 1 prices for similar assets or liabilities that are directly or indirectly observable in the marketplace. F-11 PHASEBIO PHARMACEUTICALS, INC. NOTES TO THE FINANCIAL STATEMENTS Level 3: Unobservable inputs that are supported by little or no market activity and values determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation. The Company’s cash equivalents are classified using Level 1 inputs within the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. None of the Company’s non-financial assets or liabilities are recorded at fair value on a non-recurring basis. No transfers between levels have occurred during the periods presented. The following table summarizes the Company’s assets and liabilities that require fair value measurements on a recurring basis and their respective input levels based on the fair value hierarchy (in thousands): As of December 31, 2019: Assets Cash equivalents As of December 31, 2018: Assets Cash equivalents Total Level 1 Level 2 Level 3 Fair Value Measurements at Reporting Date $ $ 73,761 $ 73,761 $ — $ 59,357 $ 59,357 $ — $ — — The following tables present activity for the preferred stock warrant liability and the derivative liability measured at fair value using significant unobservable Level 3 inputs during the year ended December 31, 2018 (in thousands): Balance at December 31, 2017 Issuance of warrants Exercise of warrants Changes in fair value reflected as change in fair value of warrant liability Conversion to common stock warrants upon IPO Balance at December 31, 2018 Balance at December 31, 2017 Changes in fair value reflected as change in fair value of derivative liability Extinguishment of derivative upon conversion of convertible promissory notes Balance at December 31, 2018 4.

The 2017 Notes bore interest at the rate of 8% per annum. Upon a subsequent equity financing of at least $10.0 million prior to the stated maturity date, the 2017 Notes plus accrued interest would automatically convert into shares of the stock issued by the Company in such financing at a price equal to 80% of the lowest issue price. The 2017 Notes could have converted into a variable number of shares of preferred stock, and accordingly, the Company determined the conversion provision to be a redemption feature. The redemption feature was evaluated as an embedded derivative and bifurcated from the convertible promissory notes due to the substantial premium paid upon redemption and accounted for as a derivative instrument. Upon bifurcating the redemption feature, the Company recorded a debt discount of $3.0 million that was recognized in interest expense over the term of the 2017 Notes. In connection with the 2017 Notes, the Company issued warrants to the noteholders to purchase 304,397 shares of Series C-1. The warrants were exercisable for $0.12 per share and expired upon the earlier of (1) the date of the initial closing of a liquidation event, as defined, (2) the closing of a firm commitment underwritten initial public offering, or (3) January 2024. All warrants were exercised in connection with the closing of the Company’s IPO. The Company recorded a debt discount of $1.7 million, which represented the estimated fair value of the warrants, upon issuance of the 2017 Notes, which was being amortized to interest expense over the term of the 2017 Notes using the effective-interest method. In August 2018, the Company sold 1,842,959 shares of Series D redeemable preferred stock (“Series D”) to new and existing investors at a price of $9.659 per share for net proceeds of $17.7 million and issued warrants to purchase 368,582 shares of Series C-1 at an exercise price of $0.12 per share (the “Series D Financing”). Concurrent with the Series D Financing, all of the Company’s previously outstanding 2017 Notes, including accrued interest thereon, were converted into 2,080,209 shares of Series D. Interest expense, including the debt discount related to the 2017 Notes, was $3.4 million for the year ended December 31, 2018. F-13 PHASEBIO PHARMACEUTICALS, INC. NOTES TO THE FINANCIAL STATEMENTS Term Loans October 2017 Loan Agreement with Silicon Valley Bank In October 2017, the Company entered into a Loan and Security Agreement (“SVB Loan”) with Silicon Valley Bank (“SVB”), pursuant to which the Company could borrow up to $7.5 million, issuable in three separate tranches (“Growth Capital Advances”) of $3.5 million (“Tranche A”), $2.0 million (“Tranche B”) and $2.0 million (“Tranche C”). Each of the Growth Capital Advances were available upon the achievement of certain clinical and regulatory milestones. Under the terms of the SVB Loan, as amended, the Company was required to make interest-only payments through December 31, 2018, followed by an amortization period of 24 months of equal monthly payments of principal plus interest amounts until paid in full. The maturity date of the SVB Loan was December 31, 2020. In connection with the SVB Loan, the Company issued to SVB a warrant to purchase 49,713 shares of Series C-1 at an exercise price of $9.659 per share, which became exercisable for common stock following the IPO. The warrant is immediately exercisable and expires on October 18, 2027. The Company was required to make a final payment equal to 7% of the original aggregate principal amount of the Growth Capital Advances at maturity. In November 2017, the Company drew $3.5 million from Tranche A. The Company had the option to prepay all, but not less than all, of the borrowed amounts, provided that the Company would have been obligated to pay a prepayment fee equal to (a) 3.0% of the outstanding principal balance of the applicable Growth Capital Advances if prepayment was made prior to the first anniversary of the effective date of the SVB Loan, (b) 2.0% of the outstanding principal balance of the applicable Growth Capital Advances if prepayment was made by the second anniversary of the effective date of the SVB Loan or (c) 1.0% of the outstanding principal balance of the applicable Growth Capital Advances if prepayment was made after the second anniversary of the effective date of the SVB Loan. The Company repaid the outstanding principal balance and accrued portion of the final payment under the SVB Loan in full using the first tranche from the new term loan entered into in March 2019 ("the 2019 Loan"). March 2019 Loan Agreement with Silicon Valley Bank and WestRiver Innovation Lending Fund VIII, L.P. In March 2019, the Company entered into the 2019 Loan with SVB and WestRiver Innovation Lending Fund VIII, L.P. (“WestRiver”), pursuant to which the Company could borrow up to $15.0 million, issuable in three separate tranches (“Advances”), of $7.5 million (“Tranche 1”), which was issued upon execution of the 2019 Loan, $2.5 million, which was issued in May 2019 (“Tranche 2”) and $5.0 million, which was issued in October 2019 (“Tranche 3”), which the Company was required to draw upon the achievement of certain regulatory milestones (the “Tranche 3 Milestones”). The maturity date of the 2019 Loan is March 1, 2023. Under the terms of the 2019 Loan, the Company is to make interest-only payments through June 30, 2020 with respect to Tranche 1, Tranche 2 and Tranche 3 at a rate equal to the greater of the Prime Rate plus 1.00%, as defined in the 2019 Loan, or 6.5%, followed by an amortization period of 33 months of equal monthly payments of principal plus interest until paid in full. In addition to and not in substitution for the Company’s regular monthly payments of principal plus accrued interest, the Company is required to make a final payment equal to 6% of the aggregate principal amount of the advances (“Final Payment”) on the maturity date. Upon execution of the 2019 Loan and the draw of Tranche 1, the Company issued to SVB and WestRiver warrants to purchase an aggregate of 37,606 shares of common stock with an exercise price of $4.73 per share. In May 2019, upon the draw of Tranche 2, the Company issued to SVB and WestRiver warrants to purchase an aggregate of 12,130 shares of common stock with an exercise price of $10.86 per share. In October 2019, upon the draw of Tranche 3, the Company issued to SVB and WestRiver warrants to purchase an aggregate of 24,262 shares of common stock with an exercise price of $3.88 per share. All warrants are immediately exercisable and expire ten years from the date of issuance. Upon execution of the 2019 Loan, the Company drew $7.5 million from Tranche 1 and repaid the outstanding principal balance and the accrued portion of the Final Payment of the SVB Loan. The Company’s obligations under the 2019 Loan are secured by a first-priority security interest in substantially all of the Company’s current and future assets. The Company is also obligated to comply with various other customary covenants, including restrictions on the Company’s ability to encumber its intellectual property assets.

Stock-Based Compensation Stock Plans In July 2018, the Company amended its Amended and Restated 2002 Stock Plan (the “2002 Plan”) to reserve an additional 800,000 shares of common stock for issuance under the 2002 Plan. In October 2018, the Company’s board of directors and stockholders adopted and approved the 2018 Equity Incentive Plan (the “2018 Plan”), which is a successor to and continuation of the 2002 Plan. The 2018 Plan became effective upon the execution of the underwriting agreement related to the IPO on October 17, 2018. No further grants will be made under the 2002 Plan. Initially, the maximum number of shares of the Company’s common stock that may be issued under the 2018 Plan was 3,231,626 shares. As of December 31, 2019, the Company had 1,221,879 shares available for grant under the 2018 Plan. The number of shares of common stock reserved for issuance under the 2018 Plan will automatically increase on January 1 of each calendar year, starting on January 1, 2019 through January 1, 2028, in an amount equal to 3% of the total number of shares of the Company’s capital stock outstanding on the last day of the calendar month before the date of each automatic increase, or a lesser number of shares determined by the Company’s board of directors. Subject to this provision, the Company added 862,992 shares available for grant to the 2018 Plan effective January 1, 2020. The maximum number of shares of the Company’s common stock that may be issued on the exercise of incentive stock options under the 2018 Plan is 9,694,878. F-16 PHASEBIO PHARMACEUTICALS, INC. NOTES TO THE FINANCIAL STATEMENTS The following table summarizes stock option activity for the 2002 Plan and 2018 Plan for the year ended December 31, 2019: Outstanding at Ended December 31, 2017 Granted Exercised Cancelled or expired Outstanding at December 31, 2018 Granted Exercised Cancelled or expired Outstanding at December 31, 2019 Vested and expected to vest at December 31, 2019 Vested and exercisable at December 31, 2019 Total Options 1,075,209 $ 563,268 $ (43,687) $ (49,387) $ 1,545,403 $ 1,260,540 $ (143,654) $ (84,571) $ 2,577,718 $ 2,577,718 $ 1,157,120 $ Weighted- Average Exercise Price Per Share Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value 1.60 4.07 2.12 1.65 2.48 4.19 1.71 4.65 3.29 3.29 2.25 7.3 $ 711,328 7.6 $ 1,593,487 7.9 $ 7.9 $ 6.7 $ 7,914,459 7,914,459 4,469,348 The weighted-average grant date fair value per share of options granted was $2.62 and $2.75 for the years ended December 31, 2019 and 2018, respectively. The aggregate intrinsic value of options exercised was $1.0 million and $0.2 million for the years ended December 31, 2019 and 2018, respectively. As of December 31, 2019, the total unrecognized compensation expense related to unvested employee and non-employee stock option awards was $3.2 million, which was expected to be recognized in expense over a weighted-average period of approximately 2.7 years. In October 2018, the Company’s board of directors and stockholders approved the 2018 Employee Stock Purchase Plan (the “ESPP”). The ESPP became effective on October 17, 2018. The purpose of the ESPP is to secure the services of new employees, to retain the services of existing employees and to provide incentives for such individuals to exert maximum efforts toward the Company’s success and that of the Company’s affiliates. The ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Code for United States employees. The ESPP authorizes the issuance of 196,000 shares of the Company’s common stock under purchase rights granted to the Company’s employees or to employees of any of the Company’s designated affiliates. The number of shares of common stock reserved for issuance will automatically increase on January 1 of each calendar year, beginning on January 1, 2019 through January 1, 2028, by the lesser of (1) 1% of the total number of shares of the Company’s common stock outstanding on the last day of the calendar month before the date of the automatic increase, and (2) 490,000 shares; provided that before the date of any such increase, the Company’s board of directors may determine that such increase will be less than the amount set forth in clauses (1) and (2). Subject to this provision, the Company added 287,664 shares available for grant to the ESPP effective January 1, 2020. As of December 31, 2019, no shares of common stock have been purchased under the ESPP. Determining Fair Value of Stock Options The fair value of each grant of stock options was determined by the Company using the methods and assumptions discussed below. Certain of these inputs are subjective and generally require judgment to determine. Expected Term—The expected term of stock options represents the weighted average period the stock options are expected to be outstanding. The Company uses the simplified method for estimating the expected term. The simplified method calculates the expected term as the average time-to- vesting and the contractual life of the options. Expected Volatility—Due to the Company’s limited operating history and lack of company-specific historical or implied volatility, the expected volatility assumption was determined by examining the historical volatilities of a group of industry peers whose share prices are publicly available. F-17 PHASEBIO PHARMACEUTICALS, INC. NOTES TO THE FINANCIAL STATEMENTS Risk-Free Interest Rate—The risk-free rate assumption is based on the United States Treasury instruments, the terms of which were consistent with the expected term of the Company’s stock options. Expected Dividend—The Company has not paid and does not intend to pay dividends. Common Stock Valuation—Due to the absence of a public market trading the Company’s common stock prior to the IPO, it was necessary to estimate the fair value of the common stock underlying the stock-based grants when performing fair value calculations using the Black-Scholes option pricing model. The fair value of the common stock underlying the stock-based grants was assessed for each grant date by the board of directors. All options to purchase shares of common stock have been granted with an exercise price per share no less than the fair value per share of the common stock underlying those options on the date of grant. In the absence of a public trading market for the Company’s common stock, the Company determined the estimated fair value of its common stock using methodologies, approaches, and assumptions consistent with the American Institute of Certified Public Accountants (“AICPA”) Audit and Accounting Practice Aid Series: Valuation of Privately Held Company Equity Securities Issued as Compensation (“AICPA Practice Aid”). The fair value of each option was estimated on the date of grant using the weighted average assumptions in the table below: Risk-free interest rate Expected term (in years) Expected volatility Expected dividend yield Fair value of common stock Year Ended December 31, 2019 2018 2.36% 5.9 69% — $ 4.19 $ 2.88% 7.0 69% — 4.07 Stock-based compensation expense has been reported in the Company’s statements of operations for the years ended December 31, 2019 and 2018 as follows (in thousands): General and administrative Research and development Total stock-based compensation 11. License Agreements MedImmune Limited Year Ended December 31, 2019 2018 $ $ 1,135 $ 286 1,421 $ 208 124 332 In November 2017, the Company entered into a license agreement (“MedImmune License”) with MedImmune Limited (“MedImmune”). MedImmune is a wholly-owned subsidiary of AstraZeneca plc (“AstraZeneca”). Pursuant to the terms of the MedImmune License, MedImmune granted the Company exclusive global rights for the purpose of developing and commercializing products under the MedImmune License (“MedImmune licensed product”). In consideration of the license and other rights granted by MedImmune, the Company made an upfront payment of $0.1 million, which was included as research and development expense for the year ended December 31, 2017. The Company is also obligated to make a series of contingent milestone payments totaling up to an aggregate of $18.0 million upon the achievement of clinical development and regulatory milestones. During the year ended December 31, 2019, the Company made a $1.0 million milestone payment to MedImmune, which was recorded as a research and development expense. In addition, the Company will pay MedImmune tiered royalties ranging from mid-single-digit to low-teen percentages of net sales of any MedImmune licensed products and additional payments of up to $50.0 million in aggregate commercial milestones. The Company also must pay quarterly fees relating to technical services provided by MedImmune.

No sales of Duke licensed products or services have occurred since the effective date through December 31, 2019. Certain alliance fee payments up to the greater of $0.3 million or a low double-digit percentage of the fees the Company receives from a third party in consideration of forming a strategic alliance, may be required depending upon how the patent rights are commercialized. The Company will pay Duke the first $1.0 million of nonroyalty payments it receives from a sublicensee, and thereafter a specified percentage of any additional nonroyalty payments it receives, subject to certain conditions. If Duke receives revenue as a result of a license or sublicense to a third party in the field of small- molecule oncologics, it will pay the Company a specified percentage of the amount of such revenue in excess of $1.0 million. Duke is also a stockholder of the Company. Wacker In April 2019, the Company entered into a license agreement (“Wacker License Agreement”), with Wacker Biotech GmbH (“Wacker”), pursuant to which Wacker granted the Company an exclusive license under certain of Wacker’s intellectual property rights to use Wacker’s proprietary E. coli strain for the manufacture of PB2452 worldwide outside of specified Asian countries, and to commercialize PB2452, if approved, manufactured by the Company or on the Company’s behalf using Wacker’s proprietary E. coli strain throughout the world. The Company has the right to grant sublicenses under the license, subject to certain conditions as specified in the Wacker License Agreement. Under the terms of the agreement, the Company is required to pay a fixed, nominal per-unit royalty, which is subject to adjustment, and an annual license fee in a fixed Euro amount in the low to mid six digits. The agreement will be in force for an indefinite period of time, and upon the expiration of the Company’s royalty obligations, the license will be considered fully paid and will convert to a non-exclusive license. Either party may terminate the Wacker License Agreement for breach if such breach is not cured within a specified number of days.

Income Taxes The Company’s loss before income taxes was $39.2 million and $23.8 million for the years ended December 31, 2019 and 2018, respectively and was generated entirely in the United States. The Company did not record current or deferred income tax expense or benefit during the years ended December 31, 2019 and 2018. A reconciliation of income tax expense (benefit) to the amount computed by applying the statutory federal income tax rate to the loss from operations is summarized for the years ended December 31, 2019 and 2018, respectively, as follows (in thousands): Income tax benefit at statutory rate State income tax, net of federal benefit Permanent items Fair value adjustments Non-deductible interest expense Stock-based compensation Orphan drug credit Research and development credits Uncertain tax positions Tax Cuts and Jobs Act Change in state rate Change in valuation allowance Other Year Ended December 31, 2019 2018 $ $ (8,242) $ (3,783) 16 — — 56 (925) (763) 548 — (34) 13,179 (52) — $ (5,008) (1,593) 3 15 706 45 (475) (274) 222 (15) — 6,426 (52) — Significant components of the Company’s deferred tax assets as of December 31, 2019 and 2018 are shown below: F-20 PHASEBIO PHARMACEUTICALS, INC.

This evaluation utilizes the framework contained in ASC 740, Income Taxes, whereby management considers all available positive and negative evidence as of the balance sheet date to determine whether all or some portion of the Company’s net deferred tax assets will be realized. Under this guidance, a valuation allowance must be established for net deferred tax assets when it is more-likely-than-not (a probability level of more than 50%) that the asset will not be realized. Management followed the guidance in ASC 740, which states that “a cumulative loss in recent years is a significant piece of negative evidence that is difficult to overcome” and concluded that the Company’s net deferred tax assets were not realizable as of December 31, 2019 and 2018. Accordingly, a valuation allowance of $50.0 million and $36.8 million has been recorded to offset the net deferred tax assets. The change in valuation allowance for the years ended December 31, 2019 and 2018 was an increase of $13.2 million and an increase of $6.4 million, respectively. At December 31, 2019, the Company had federal and state net operating loss (“NOL”) carryforwards of $149.0 million, and $153.4 million, respectively. The federal NOLs generated prior to 2018 may be used to offset up to 100% of future taxable income and will begin to expire in 2022, unless previously utilized. The federal NOL generated post-2017 of $57.4 million will be available to offset up to 80% of future taxable income and may be carried forward indefinitely. The Pennsylvania NOLs may be used to offset 40% of future taxable income and will begin to expire in 2029, unless previously utilized. At December 31, 2019, the Company has federal and Pennsylvania research and development tax credit carryforwards totaling $3.8 million and $0.4 million, respectively. The federal and Pennsylvania research and development tax credit carryforwards will begin to expire in 2028 and 2029, respectively, unless previously utilized. At December 31, 2019, the Company also has federal orphan drug credit carryforwards of $4.2 million, which will begin to expire in 2036, unless previously utilized. Through December 31, 2019, the Company has generated a combination of research and development credits and orphan drug credits. Certain of these credits were derived from tax credit studies to document the qualified activities and certain other credits were not derived from studies. For the credits that were calculated through a study, the IRS, on audit, may disagree with the amount of credits calculated. When studies are ultimately performed for the other credits, they may result in an adjustment to those specific credits. Under the Internal Revenue Code, the utilization of a corporation’s net operating loss and tax credit carryforwards may be limited following a greater than 50% change in ownership over a three-year period. Any unused annual limitation may F-21 PHASEBIO PHARMACEUTICALS, INC. NOTES TO THE FINANCIAL STATEMENTS be carried forward to future years for the balance of the net operating loss and tax credit carryforward period. Under these rules, prior ownership changes may have created a limitation in the Company’s ability to use certain tax carryforwards on a yearly basis. Additionally, certain state operating losses may also be limited, including Pennsylvania, which limits net operating loss carryforward utilization to 40% of apportioned taxable income. The Company applies the two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount, which is more than 50% likely of being realized upon ultimate settlement. Income tax positions must meet a more likely than not recognition threshold at the effective date to be recognized upon the adoption of ASC 740 and in subsequent periods. This interpretation also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company files income tax returns in the United States federal jurisdiction and various state jurisdictions. Tax years 2016 and forward remain open for examination for federal tax purposes and tax years 2016 and forward remain open for examination for the Company’s more significant state tax jurisdictions. To the extent utilized in future years’ tax returns, net operating loss carryforwards at December 31, 2019 will remain subject to examination until the respective tax year is closed. The following table summarizes the activity related to the Company’s gross unrecognized tax benefits for the years ended December 31, 2019 and 2018 (in thousands): Gross unrecognized tax benefits at the beginning of the year Increases related to current year positions Increases related to prior year positions Decreases related to prior year positions Expiration of unrecognized tax benefits Gross unrecognized tax benefits at the end of the year Year Ended December 31 2019 2018 1,809 $ 1,293 645 106 — — 362 154 — — 2,560 $ 1,809 $ $ Due to the Company's valuation allowance, none of the unrecognized tax benefits, if recognized, would affect the Company's effective tax rate. As of December 31, 2019, and 2018, the Company had unrecognized tax benefits of $2.6 million and $1.8 million, respectively. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. During the years ended December 31, 2019 and 2018, the Company did not accrue any interest and penalties on uncertain tax positions. The Company does not expect its unrecognized tax benefits to change significantly within the next 12 months. 14. Employee Retirement Plan The Company has an employee retirement plan pursuant to Section 401(k) of the Internal Revenue Code. All employees are eligible to participate, provided they meet the requirements of this plan. The Company is not required to make matching contributions under the plan; however, in 2019, the Company began making matching contributions. The Company voluntarily contributed $0.1 million to the plan for the year ended December 31, 2019. 15. Related Party Transactions As described above in Note 11, the Company is party to the MedImmune License. AstraZeneca, the parent company of MedImmune, is a related party of the Company. 16. Subsequent Events Co-Development Agreement for PB2452 with SFJ Pharmaceuticals In January 2020, the Company entered into the SFJ Agreement, pursuant to which SFJ will provide funding to the Company to support the global development of PB2452 as a reversal agent for the antiplatelet drug ticagrelor in patients with uncontrolled major or life-threatening bleeding or requiring urgent surgery or an invasive procedure. Under the SFJ Agreement, SFJ has agreed to pay the Company up to $120.0 million to support the clinical development of PB2452. In March 2020, SFJ F-22 PHASEBIO PHARMACEUTICALS, INC. NOTES TO THE FINANCIAL STATEMENTS paid the Company an initial $10.0 million. SFJ will pay the Company an additional $80.0 million through cost reimbursements followed by six equal quarterly payments beginning with the quarter ending September 30, 2020 through the quarter ending December 31, 2021, and up to an additional $30.0 million upon the achievement of specified clinical development milestones with respect to the Company's clinical development of PB2452. If the FDA approves a Biologics License Application for PB2452, the Company has agreed to pay to SFJ an initial payment of $5.0 million and an additional $325.0 million in the aggregate in seven additional annual payments (the “U.S. Approval Payments”). If the EMA or the national regulatory authorities in certain European countries provide marketing approval of PB2452, the Company will pay SFJ an initial payment of $5.0 million and an additional $205.0 million in the aggregate in seven additional annual payments (the “EU Approval Payments”). The majority of the U.S. Approval Payments and the EU Approval Payments will be made from the third anniversary to the seventh anniversary of marketing approval in the applicable jurisdiction. If either the Pharmaceuticals and Medical Devices Agency (the “PMDA”) of Japan or the National Medical Products Administration (the “NMPA”) of China provide marketing approval of PB2452, the Company will pay SFJ an initial payment of $1.0 million and then an additional $59.0 million in the aggregate in eight additional annual payments (the “Japan/China Approval Payments”), with the majority of the payments to be made from the fifth anniversary to the eighth anniversary of marketing approval. The Japan/China Approval Payments will only be paid once regardless of receipt of marketing approval in both Japan and China. The U.S. Approval Payments, EU Approval Payments and Japan/China Approval Payments will be proportionately adjusted in the event that the actual funding from SFJ is lower or greater than $120.0 million. The Company will not be obligated to make the U.S. Approval Payments if it does not receive marketing approval for PB2452 from the FDA, the EU Approval Payments if it does not receive marketing approval for PB2452 from the EMA or the national regulatory authority in certain European countries or the Japan/China Approval Payments if it does not receive marketing approval for PB2452 from either the PMDA or the NMPA. In connection with the SFJ Agreement, the Company issued to SFJ a ten-year warrant exercisable for 2,200,000 shares of the Company's common stock at an exercise price of $6.50 per share. The warrant is exercisable as follows: (i) 1,100,000 shares may be exercised at any time after the effective date of the SFJ Agreement, provided that SFJ may not sell such exercised shares until one year after such effective date, and (ii) the remaining 1,100,000 shares may be exercised at any time at SFJ’s election if the results of the Company’s Phase 3 trial meet the interim primary endpoint as set forth in the Phase 3 trial protocol.

Viamet Asset Purchase Agreement In January 2020, the Company entered into an asset purchase agreement (the "PB6440 Agreement") with Viamet Pharmaceuticals Holdings, LLC ("Viamet") and its wholly-owned subsidiary, Selenity Therapeutics (Bermuda), Ltd.

Pursuant to the First Amendment, the Lenders consented to the Company's entry into the SFJ Agreement, which required that the Company obtain the consent of SVB to grant SFJ a security interest in all of the Company’s assets owned or controlled by the Company that are necessary for the manufacture, use or sale of PB2452.

In connection with the First Amendment, the Company and the Lenders concurrently entered into an intellectual property security agreement granting the Lenders a security interest in all of the Company’s intellectual property. In addition, the Company, SVB, in its capacity as administrative agent and collateral agent, the Lenders and SFJ entered into a subordination agreement pursuant to which SFJ’s liens and right to payment and performance under the SFJ Agreement are subordinated to the Lenders’ liens and right to payment in full under the 2019 Loan.

Warrant Price: $6.5049 per share Issue Date: January 9, 2020 Expiration Date: January 9, 2020 See also Section 5.1(b). Co-Development Agreement: This Warrant to Purchase Common Stock (“Warrant”) is issued in connection with the certain Co- Development Agreement dated as of January 9, 2020 by and between SFJ Pharmaceuticals X, Ltd. and the Company (as the same may from time to time be amended, modified, supplemented or restated) (the “Agreement”). THIS WARRANT CERTIFIES THAT, for good and valuable consideration, SFJ PHARMACEUTICALS X, LTD. (together with any successor or permitted assignee or transferee of this Warrant or of any shares issued upon exercise hereof, “Holder”) is entitled to purchase the number of fully paid and non-assessable shares (the “Shares”) of the above-stated common stock (the “Common Stock”) of PHASEBIO PHARMACEUTICALS, INC. (the “Company”) at the above-stated Warrant Price, which for the avoidance of doubt, shall be calculated in accordance with Section 8.1 of the Agreement (i.e., the per-share Warrant Price shall be equal to the greater of $5.00 or 120% of the volume weighted average closing price of the Company’s common stock over the thirty (30) consecutive trading days preceding the Effective Date, all as set forth above and as adjusted pursuant to Section 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant. SECTION 1. EXERCISE. 1.1 Method of Exercise. Holder may at any time and from time to time through 6:00 PM, Pacific time, on the Expiration Date, exercise this Warrant, subject to the limitations set forth in the recitals above, in whole or in part, by delivering to the Company the original of this Warrant together with a duly executed Notice of Exercise in substantially the form attached hereto as Appendix 1 and, unless Holder is exercising this Warrant pursuant to a cashless exercise set forth in Section 1.2, a check, wire transfer of same-day funds (to an account designated by the Company), or other form of payment acceptable to the Company for the aggregate Warrant Price for the Shares being purchased. 1.2 Cashless Exercise. On any exercise of this Warrant, in lieu of payment of the aggregate Warrant Price in the manner as specified in Section 1.1 above, but otherwise in accordance with the requirements of Section 1.1, Holder may elect to receive Shares equal to the value of this Warrant, or portion hereof as to which this Warrant is being exercised. Thereupon, the Company shall issue to the Holder such number of fully paid and non-assessable Shares as are computed using the following formula: X = Y(A-B)/A where: X = the number of Shares to be issued to the Holder; the Company in payment of the aggregate Warrant Price); Y = the number of Shares with respect to which this Warrant is being exercised (inclusive of the Shares surrendered to A = the Fair Market Value (as determined pursuant to Section 1.3 below) of one Share; and B = the Warrant Price. 1.3 Fair Market Value. If the Company’s Common Stock is then traded or quoted on a nationally recognized securities exchange, inter-dealer quotation system or over-the-counter market (a “Trading Market”), the fair market value of a Share shall be the closing price or last sale price of a share of Common Stock reported for the Business Day immediately before the date on which Holder delivers this Warrant together with its Notice of Exercise to the Company. If the Company’s Common Stock is not traded in a Trading Market, the Board of Directors of the Company shall determine the fair market value of a Share in its reasonable good faith judgment. 1.4 Delivery of Certificate and New Warrant. Within a reasonable time after Holder exercises this Warrant in the manner set forth in Section 1.1 or 1.2 above, the Company shall deliver to Holder a certificate representing the Shares issued to Holder upon such exercise (which certificate may be in the form of an electronic certificate or DTC entry, to the extent used by the Company at the time of such exercise) and, if this Warrant has not been fully exercised and has not expired, a new warrant of like tenor representing the Shares not so acquired. 1.5 Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form, substance and amount to the Company or, in the case of mutilation, on surrender of this Warrant to the Company for cancellation, the Company shall, within a reasonable time, execute and deliver to Holder, in lieu of this Warrant, a new warrant of like tenor and amount. 1.6 Treatment of Warrant Upon Acquisition of Company. (a) Acquisition. For the purpose of this Warrant, “Acquisition” means any transaction or series of related transactions involving: (i) the sale, lease, exclusive license, or other disposition of all or substantially all of the assets of the Company (ii) any merger or consolidation of the Company into or with another person or entity (other than a merger or consolidation effected exclusively to change the Company’s domicile), or any other corporate reorganization, in which the stockholders of the Company in their capacity as such immediately prior to such merger, consolidation or reorganization, own less than a majority of the Company’s (or the surviving or successor entity’s) outstanding voting power immediately after such merger, consolidation or reorganization; or (iii) any sale or other transfer by the stockholders of the Company of shares representing at least a majority of the Company’s then-total outstanding combined voting power. the Company’s stockholders consists solely of cash, solely of Marketable Securities or a combination (b) Treatment of Warrant at Acquisition. In the event of an Acquisition in which the consideration to be received by of cash and Marketable Securities (a “Cash/Public Acquisition”), and the fair market value of one Share as determined in accordance with Section 1.3 above would be greater than the Warrant Price in effect on such date immediately prior to the closing of such Cash/Public Acquisition, and Holder has not exercised this Warrant pursuant to Section 1.1 above as to all Shares, then this Warrant shall automatically be deemed to be Cashless Exercised pursuant to Section 1.2 above as to all Shares effective immediately prior to and contingent upon the consummation of a Cash/Public Acquisition. In connection with such Cashless Exercise, Holder shall be deemed to have restated each of the representations and warranties in Section 4 of the Warrant as the date thereof and the Company shall promptly notify the Holder of the number of Shares (or such other securities) issued upon exercise. In the event of a Cash/Public Acquisition where the fair market value of one Share as determined in accordance with Section 1.3 above would be less than the Warrant Price in effect immediately prior to such Cash/Public Acquisition, then this Warrant will expire immediately prior to the consummation of such Cash/Public Acquisition. Notwithstanding the foregoing, in the event of an Acquisition in which the consideration to be received by the Company’s stockholders consists solely of Marketable Securities or a combination of cash and Marketable Securities and the fair market value of one Share as determined in accordance with Section 1.3 above would be less than or equal to 150% of the Warrant Price in effect on such date immediately prior to the closing of such Acquisition, then such Acquisition will not be deemed to be a Cash/Public Acquisition and the provisions of Section 1.6(c) below shall apply with respect to such Acquisition. (c) Upon the closing of any Acquisition other than a Cash/Public Acquisition, the acquiring, surviving or successor entity shall assume the obligations of this Warrant, and this Warrant shall thereafter be exercisable for the same securities and/or other property as would have been paid for the Shares issuable upon exercise of the unexercised portion of this Warrant as if such Shares were outstanding on and as of the closing of such Acquisition, subject to further adjustment from time to time in accordance with the provisions of this Warrant. (d) As used in this Warrant, “Marketable Securities” means securities meeting all of the following requirements: (i) the issuer thereof is then subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is then current in its filing of all required reports and other information under the Act and the Exchange Act; (ii) the class and series of shares or other security of the issuer that would be received by Holder in connection with the Acquisition were Holder to exercise this Warrant on or prior to the closing thereof is then traded in a Trading Market, and (iii) following the closing of such Acquisition, Holder would not be restricted from publicly re-selling all of the issuer’s shares and/or other securities that would be received by Holder in such Acquisition were Holder to exercise or convert this Warrant in full on or prior to the closing of such Acquisition, except to the extent that any such restriction (x) arises solely under federal or state securities laws, rules or regulations, and (y) does not extend beyond six (6) months from the closing of such Acquisition. 1.7 Agreement Not to Sell Tranche A Shares. Holder, and any affiliate of Holder, will not offer, sell, contract to sell, pledge or otherwise dispose of, or enter into any transaction that is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise), directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act and the rules and regulations of the Securities and Exchange Commission promulgated thereunder with respect to the Tranche A Shares for a period of one (1) year from the Effective Date. For the avoidance of doubt, this Section 1.7 does not apply to the Tranche B Shares. SECTION 2. ADJUSTMENTS TO THE SHARES AND WARRANT PRICE. 2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend or distribution on the outstanding shares of the Common Stock payable in securities or property (other than cash), then upon exercise of this Warrant, for each Share acquired, Holder shall receive, without additional cost to Holder, the total number and kind of securities and property which Holder would have received had Holder owned the Shares of record as of the date the dividend or distribution occurred. If the Company subdivides the outstanding shares of the Common Stock by reclassification or otherwise into a greater number of shares, the number of Shares purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased. If the outstanding shares of the Common Stock are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased and the number of Shares shall be proportionately decreased. 2.2 Reclassification, Exchange, Combinations or Substitution. Upon any event whereby all of the outstanding shares of the Common Stock are reclassified, exchanged, combined, substituted, or replaced for, into, with or by Company securities of a different class and/or series, then from and after the consummation of such event, this Warrant will be exercisable for the number, class and series of Company securities that Holder would have received had the Shares been outstanding on and as of the consummation of such event, and subject to further adjustment thereafter from time to time in accordance with the provisions of this Warrant. The provisions of this Section 2.2 shall similarly apply to successive reclassifications, exchanges, combinations substitutions, replacements or other similar events. 2.3 No Fractional Share. No fractional Share shall be issuable upon exercise of this Warrant and the number of Shares to be issued shall be rounded down to the nearest whole Share. If a fractional Share interest arises upon any exercise of the Warrant, the Company shall eliminate such fractional Share interest by paying Holder in cash the amount computed by multiplying the fractional interest by (i) the fair market value (as determined in accordance with Section 1.3 above) of a full Share, less (ii) the then-effective Warrant Price. 2.4 Notice/Certificate as to Adjustments. Upon each adjustment of the Warrant Price, Common Stock and/or number of Shares, the Company, at the Company’s expense, shall notify Holder in writing within a reasonable time setting forth the adjustments to the Warrant Price, class and/or number of Shares and facts upon which such adjustment is based. The Company shall, upon written request from Holder, furnish Holder with a certificate of its Chief Financial Officer, including computations of such adjustment and the Warrant Price, class and number of Shares in effect upon the date of such adjustment. SECTION 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY. 3.1 Representations and Warranties. The Company represents and warrants to, and agrees with, the Holder that all Shares which may be issued upon the exercise of this Warrant, shall, upon issuance, be duly authorized, validly issued, fully paid and non- assessable, and free of any liens and encumbrances except for restrictions on transfer provided for herein or under applicable federal and state securities laws. The Company covenants that it shall at all times cause to be reserved and kept available out of its authorized and unissued capital stock such number of securities as will be sufficient to permit the exercise in full of this Warrant. 3.2 Notice of Certain Events. If the Company proposes at any time to: (a) declare any dividend or distribution upon the outstanding shares of the Company’s stock, whether in cash, property, stock, or other securities and whether or not a regular cash dividend; (b) offer for subscription or sale pro rata to the holders of the outstanding shares any additional shares of any class or series of the Company’s stock (other than pursuant to contractual pre- emptive rights); (c) effect any reclassification, exchange, combination, substitution, reorganization or recapitalization of the outstanding shares of the Common Stock; or (d) effect an Acquisition or to liquidate, dissolve or wind up; then, in connection with each such event, the Company shall give Holder notice thereof at the same time and in the same manner as given to holders of the outstanding shares of the Common Stock. SECTION 4. REPRESENTATIONS, WARRANTIES OF THE HOLDER. The Holder represents and warrants to the Company as follows: 4.1 Purchase for Own Account.

Section 4 of the Warrant to Purchase Common Stock as of the date hereof.

By:___________________________________ Name:_________________________________ Title:__________________________________ (Date):_________________________________ DESCRIPTION OF PHASEBIO PHARMACEUTICALS, INC. COMMON STOCK The following description of the common stock of PhaseBio Pharmaceuticals, Inc., or the Company, is a summary and does not purport to be complete. This summary is qualified in its entirety by reference to the provisions of the Delaware General Corporation Law, or the DGCL, and the complete text of the Company’s amended and restated certificate of incorporation, or certificate of incorporation, and amended and restated bylaws, or the bylaws, which are incorporated by reference as Exhibits 3.1 and 3.2, respectively, of the Company’s Annual Report on Form 10-K to which this description is also an exhibit. The Company encourages you to read that law and those documents carefully. Exhibit 4.11 Common Stock Authorized Capital Stock The certificate of incorporation authorizes the issuance of up to 200,000,000 shares of common stock, $0.001 par value per share, and 10,000,000 shares of preferred stock, $0.001 par value per share. The Company’s board of directors may establish the rights and preferences of the preferred stock from time to time. Voting Rights Each holder of common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Under the certificate of incorporation and bylaws, common stockholders do not have cumulative voting rights. Because of this, the holders of a majority of the shares of common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they should so choose. Dividends Subject to preferences that may be applicable to any then-outstanding preferred stock, holders of common stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by the board of directors out of legally available funds. Liquidation In the event of the Company’s liquidation, dissolution or winding up, holders of common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then-outstanding shares of preferred stock. Rights and Preferences Holders of common stock have no preemptive, conversion or subscription rights and there are no redemption or sinking fund provisions applicable to the common stock. The rights, preferences and privileges of the holders of common stock are subject to, and may be adversely affected by, the right of the holders of shares of any series of preferred stock that the Company may designate in the future. Anti-Takeover Provisions Section 203 of the Delaware General Corporation Law The Company is subject to Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions: ● ● ● before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder; upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding, but not the outstanding voting stock owned by the interested stockholder, those shares owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2⁄3% of the outstanding voting stock that is not owned by the interested stockholder. In general, Section 203 defines a business combination to include the following: ● ● ● ● ● any merger or consolidation involving the corporation or any direct or indirect majority-owned subsidiary of the corporation and the interested stockholder; any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder (in one transaction or a series of transactions); subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation or by any direct or indirect majority-owned subsidiary of the corporation of any stock of the corporation or of such subsidiary to the interested stockholder; any transaction involving the corporation or any direct or indirect majority-owned subsidiary of the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or through the corporation. In general, Section 203 defines an interested stockholder as an entity or person who, together with the person's affiliates and associates, beneficially owns, or within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation. Anti-Takeover Effects of Certain Provisions of the Certificate of Incorporation and Bylaws The certificate of incorporation provides for the Company’s board of directors to be divided into three classes with staggered three-year terms. Only one class of directors will be elected at each annual meeting of stockholders, with the other classes continuing for the remainder of their respective three-year terms. Because the Company’s stockholders do not have cumulative voting rights, stockholders holding a majority of the shares of common stock outstanding will be able to elect all of the Company’s directors. The certificate of incorporation and bylaws also provide that directors may be removed by the stockholders only for cause upon the vote of 66 2⁄3% or more of the Company’s outstanding common stock. Furthermore, the authorized number of directors may be changed only by resolution of the board of directors, and vacancies and newly created directorships on the board of directors may, except as otherwise required by law or determined by the board, only be filled by a majority vote of the directors then serving on the board, even though less than a quorum. The certificate and incorporation and bylaws also provide that all stockholder actions must be effected at a duly called meeting of stockholders and will eliminate the right of stockholders to act by written consent without a meeting. The Company’s bylaws also provide that only the Chairman of the board, Chief Executive Officer or the board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors may call a special meeting of stockholders. The bylaws also provide that stockholders seeking to present proposals before the meeting of stockholders to nominate candidates for election as directors at a meeting of stockholders must provide timely advance notice in writing, and specifies requirements as to the form and content of a stockholder's notice. The certificate of incorporation and bylaws provide that the stockholders cannot amend many of the provisions described above except by a vote of 66 2⁄3% or more of the Company’s outstanding common stock. The combination of these provisions could make it more difficult for the Company’s existing stockholders to replace the board of directors as well as for another party to obtain control of the Company by replacing the board of directors. Since the board of directors has the power to retain and discharge the Company’s officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for the board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change the Company’s control. These provisions are intended to enhance the likelihood of continued stability in the composition of the board of directors and its policies and to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to reduce the Company’s vulnerability to hostile takeovers and to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for the Company’s shares and may have the effect of delaying changes in control or management. As a consequence, these provisions may also inhibit fluctuations in the market price of the Company’s stock that could result from actual or rumored takeover attempts. The Company believes that the benefits of these provisions, including increased protection of its potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure the Company, outweigh the disadvantages of discouraging takeover proposals, because negotiation of takeover proposals could result in an improvement of their terms. Choice of Forum The certificate of incorporation provides that the Court of Chancery of the state of Delaware will be the exclusive forum for: ● any derivative action or proceeding brought on the Company’s behalf; ● any action asserting a breach of fiduciary duty; ● any action asserting a claim against us arising pursuant to the DGCL, the Company’s certificate of incorporation or the bylaws; or ● any action asserting a claim against the Company that is governed by the internal affairs doctrine. The enforceability of similar choice of forum provisions in other companies' certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with any action, a court could find the choice of forum provisions contained in the Company’s certificate of incorporation to be inapplicable or unenforceable in such action. The Company’s certificate of incorporation provides that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. Recently, the Court of Chancery of the State of Delaware issued an opinion invalidating the federal district court exclusive forum provision. In light of that recent decision, the Company will not attempt to enforce this provision of its certificate to the extent it is not permitted by applicable law. However, if the decision is reviewed on appeal and ultimately overturned by the Delaware Supreme Court, the Company would enforce the federal district court exclusive forum provision. Transfer Agent and Registrar The transfer agent and registrar for the Company’s common stock is Computershare Trust Company, N.A. The transfer agent's address is 250 Royall Street, Canton, Massachusetts 02021.

GRANT OF AUTHORITY; AGREEMENTS OF SUBORDINATED CREDITOR In the event of the occurrence of an Insolvency Event, and in order to enable each Senior Creditor to enforce its rights hereunder in any of the aforesaid actions or proceedings, each Senior Creditor is hereby irrevocably authorized and empowered, in such Senior Creditor’s discretion, as follows: (a) Such Senior Creditor is hereby irrevocably authorized and empowered (in its own name or in the name of Subordinated Creditor or otherwise), but shall have no obligation, ((i) to demand, sue for, collect and receive every payment or distribution referred to in Section 6, and give acquittance therefor and, (ii) (if Subordinated Creditor has failed to file claims or proofs of claim on or before five (5) Business Days prior to the last date such claims or proofs of claim may be filed pursuant to law or the order of any court exercising jurisdiction over such proceeding) to file claims and proofs of claim, and (iii) to take such other action (including, without limitation, enforcing any Lien securing payment of the Subordinated Debt) as it may deem necessary or advisable for the exercise or enforcement of any of the rights or interests of either Senior Creditor hereunder. Subordinated Creditor shall duly and promptly take such action as each Senior Creditor may reasonably request to execute and deliver to each Senior Creditor such authorizations, endorsements, assignments, or other instruments as each Senior Creditor may reasonably request in order to enable each Senior Creditor to enforce any and all claims with respect to, and any Lien securing payment of, the Subordinated Debt as such enforcement is contemplated herein. (b) To the extent that payments or distributions on account of the Subordinated Debt are made in property or securities other than cash, Subordinated Creditor authorizes each Senior Creditor, to sell or dispose of such property or securities on such terms as are commercially reasonable in the situation in question. Following full payment in cash of the Senior Debt, each Senior Creditor shall remit to Subordinated Creditor (with all necessary endorsements), to the extent of Subordinated Creditor’s interest therein, all payments and distributions of cash, property, or securities paid to and held by any Senior Creditor in excess of the allowed amount of the Senior Debt. In addition to and without limiting the foregoing: (a) so long as the Discharge of Senior Debt has not occurred, Subordinated Creditor shall not commence or join in any involuntary bankruptcy petition or similar judicial proceeding against Borrower except upon written consent of Senior Creditor, and (b) if an Insolvency Event occurs: (i) Subordinated Creditor shall not assert, without the prior written consent of each Senior Creditor, any claim, motion, objection or argument in respect of the Collateral in connection with any Insolvency Event which could otherwise be asserted or raised in connection with such Insolvency Event, including, without limitation, any claim, motion, objection or argument seeking adequate protection (except, however, that Subordinated Creditor may do so to the same extent Senior Creditor has sought adequate protection) or relief from the automatic stay in respect of the Collateral, (ii) Senior Creditors may consent to the use of cash collateral on such terms and conditions and in such amounts as it shall in good faith determine without seeking or obtaining the consent of Subordinated Creditor as (if applicable) holder of an interest in the Collateral, (iii) if use of cash collateral by Borrower is consented to by Senior Creditors, Subordinated Creditor shall not oppose such use of cash collateral on the basis that Subordinated Creditor’s interest in the Collateral (if any) is impaired by such use or inadequately protected by such use, or on any other ground, and (iv) Subordinated Creditor shall not object to, or oppose, any sale or other disposition of any assets comprising all or part of the Collateral, free and clear of Liens and claims of any party, including Subordinated Creditor, under Section 363 of the United States Bankruptcy Code or otherwise, on the basis that the interest of Subordinated Creditor in the Collateral (if any) is impaired by such sale or inadequately protected as a result of such sale, or on any other ground (and, if requested by either Senior Creditor, Subordinated Creditor shall affirmatively and promptly consent to such sale or disposition of such assets), if Senior Creditors have consented to, or supports, such sale or disposition of such assets. 8. PAYMENTS RECEIVED BY SUBORDINATED CREDITOR Should any payment, distribution, or security be received by Subordinated Creditor upon or with respect to the Subordinated Debt (other than any payment of Subordinated Debt permitted pursuant to Section 3) prior to termination of this Agreement in accordance with Section 10, Subordinated Creditor shall receive and hold the same in trust for the benefit of each Senior Creditor and shall forthwith deliver the same to Senior Creditors in precisely the form received (except for the endorsement or assignment of Subordinated Creditor where necessary) for application to the Senior Debt, and, until so delivered, the same shall be held in trust by Subordinated Creditor as the property of Senior Creditors. 9. FURTHER ASSURANCES. Subject to Section 16(b), each of Senior Creditor and Subordinated Creditor agrees to take all further actions and execute and deliver such additional documents and instruments (in recordable form, if requested) as the other parties hereto may reasonably request to effectuate the terms of, and the lien priorities contemplated by, this Agreement. 10. TERMINATION OR AMENDMENT OF AGREEMENT This Agreement shall be effective upon its execution by each of Senior Agent, Senior Creditors and Subordinated Creditor. After the Effective Date, this Agreement may be amended or waived in writing signed by Senior Creditor and Subordinated Creditor. Senior Creditors and Subordinated Creditor agree that no amendment hereto shall be binding upon Borrower unless Borrower shall have received notice of such amendment. Subject to Section 14, this Agreement shall automatically and without further action terminate upon the Discharge of Senior Debt. 11. ADDITIONAL AGREEMENTS FOR SENIOR AGENT AND SENIOR CREDITORS Senior Agent and Senior Creditors may administer and manage their credit and other relationships with Borrower in its own best interest, without notice to or consent of Subordinated Creditor. At any time and from time to time, Senior Agent and Senior Creditors may enter into any amendment or agreement with Borrower as Senior Creditors may deem proper, extending the time of payment of or renewing or otherwise altering the terms of all or any of the obligations constituting Senior Debt or affecting the collateral security for, supporting or underlying any or all of the Senior Debt, and may exchange, sell, release, surrender or otherwise deal with any such collateral without in any way thereby impairing or affecting this Agreement, and all such additional agreements and amendments shall be Senior Loan Documents evidencing the Senior Debt; provided, that neither this Section 11 nor any provision of such agreements shall affect the limitations contained in the definition of Senior Debt. 12. SUBROGATION If cash or other property otherwise payable or deliverable to Subordinated Creditor or on account of the Subordinated Debt shall have been applied pursuant to this Agreement to the payment of the Senior Debt, and if the Discharge of Senior Debt has occurred, then Subordinated Creditor shall be subrogated to any rights of Senior Creditors to receive further payments or distributions applicable to the Senior Debt until the Subordinated Debt shall have been fully paid. No such payments or distributions received by Subordinated Creditor by reason of such subrogation shall, as between Borrower and its creditor other than Senior Creditors, on the one hand, and Subordinated Creditor, on the other hand, be deemed to be a payment by Borrower on account of the Subordinated Debt owed to Subordinated Creditor. 13. AMENDMENTS (a) Subordinated Creditor shall have the right to amend the Subordinated Loan Documents at any time, provided that without Senior Agent’s consent such amendment shall not (i) restrict the Borrower’s ability to repay the Senior Debt in any respect, (ii) accelerate or otherwise shorten the payment schedule under the Subordinated Loan Documents or (iii) increase the amount of any scheduled payment under the Subordinated Loan Documents. 14. REINSTATEMENT OF SENIOR DEBT To the extent that Senior Agent or Senior Creditors receives payments on or proceeds of any collateral security for the Senior Debt, which payments or proceeds are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, receiver or any other party under any bankruptcy law, state or federal law, common law, or equitable cause, then, to the extent of such payments or proceeds invalidated, declared to be fraudulent or preferential, set aside or required to be repaid, the Senior Debt, or part thereof, intended to be satisfied shall be revived and continue in full force and effect as if such payments or proceeds had not been received by Senior Agent or Senior Creditors. 15. NO WAIVERS None of Senior Agent, Senior Creditors or Subordinated Creditor shall be prejudiced in their rights under this Agreement by any act or failure to act of any party hereto or any noncompliance of any other party hereto with any agreement or obligation, regardless of any knowledge thereof which Senior Agent, Senior Creditors or Subordinated Creditor, as applicable, may have, or with which Senior Agent or Senior Creditors may be charged; no action permitted hereunder that has been taken by any party hereto shall in any way affect or impair the rights or remedies of such party in the exercise of any other right or remedy or shall operate as a waiver thereof; no single or partial exercise by any party hereto of any right or remedy shall preclude any other or further exercise thereof; and no modification or waiver of any of the provisions of this Agreement shall be binding upon any party hereto, in each case except as expressly set forth in a writing duly signed and delivered by such party. 16. INFORMATION CONCERNING BORROWER; CREDIT ADMINISTRATION (a) Subordinated Creditor hereby assumes responsibility for keeping itself informed of the financial condition of Borrower, any and all endorsers and any and all guarantors of the Senior Debt and of all other circumstances bearing upon the risk of nonpayment of the Senior Debt or the Subordinated Debt that diligent inquiry would reveal, and Subordinated Creditor hereby agrees that Senior Agent or Senior Creditors shall not have any duty to advise Subordinated Creditor of information known to Senior Agent or Senior Creditors regarding such condition. (b) Subject to Sections 2(b), 3, 4, 7 and 8, Subordinated Creditor may (i) administer and manage its credit and other relationships with Borrower in its own best interest, and (ii) amend or extend its agreements with Borrower or enter into additional agreements with Borrower, all without the consent of or notice to Senior Agent or Senior Creditors; provided that neither this Section 16(b) nor any amendments or additional agreements referred to therein shall impair or affect the subordination of Subordinated Debt or change the definition of Permitted Payments, Subordinated Debt, Subordinated Creditor, Senior Debt or Senior Creditor. 17. NOTICES Except as otherwise provided herein, all notices and service of process required, contemplated, or permitted hereunder or with respect to the subject matter hereof shall be in writing, and shall be deemed to have been validly served, given or delivered upon the earlier of: (a) the first business day after transmission by facsimile or hand delivery or deposit with an overnight express service or overnight mail delivery service; or (b) the third calendar day after deposit in the United States mails, with proper first class postage prepaid, and shall be addressed to the party to be notified as follows: If to Borrower: If to Agent or SVB: If to WestRiver: If to Subordinated Creditor: 18.

GOVERNING LAW This Agreement shall be governed by and interpreted in accordance with the laws of the State of California without regard to principles of conflict of laws that would cause the application of laws of any other jurisdiction. 20. ASSIGNMENT This Agreement shall be binding upon Senior Creditor, Subordinated Creditor, the Borrower and their respective successors and assigns, and shall inure to the benefit of and be enforceable by Senior Agent or Senior Creditors and their successors and assigns. 21. CONSENT Senior Agent and each Senior Creditor hereby consents to the Liens in the Subordinated Collateral and the indebtedness and other obligations created or to be created under Subordinated Agreement and agrees that the grant or existence of such Lien does not and shall not constitute a default or an event of default under or a breach of the Senior Loan Documents or this Agreement. Subordinated Creditor hereby consents to the Lien on the Senior Collateral and the indebtedness created or to be created under the Senior Creditor Agreement and agrees that the grant or existence of such Liens does not and shall not constitute a default or an event of default under the Subordinated Loan Documents. 22. WAIVER AND JUDICIAL REFERENCE TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, SUBORDINATED CREDITOR AND SENIOR CREDITOR EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE SENIOR LOAN DOCUMENTS, THE SUBORDINATED LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY, AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR THE PARTIES HERETO TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. WITHOUT INTENDING IN ANY WAY TO LIMIT THE PARTIES’ AGREEMENT TO WAIVE THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY, if the above waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time shall be decided by a reference to a private judge, mutually selected by the parties hereto (or, if they cannot agree, by the Presiding Judge of the Santa Clara County, California Superior Court) appointed in accordance with California Code of Civil Procedure Section 638 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts), sitting without a jury, in Santa Clara County, California; and the parties hereto hereby submit to the jurisdiction of such court. The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers. All such proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference procedures, then such party may apply to the Santa Clara County, California Superior Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee discovery and may enforce all discovery rules and order applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to the California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph. 23. COUNTERPARTS This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all of which counterparts together shall constitute but one and the same instrument. 24. PURCHASE OPTION (a) In the event that (i) a Blockage Notice has been issued, or (ii) the Senior Debt is accelerated by Senior Creditors (each a “Purchase Trigger Event”), Subordinated Creditor shall have the option (but not the obligation) to purchase all (but not less than all) of the then-outstanding Senior Debt; provided that such option shall expire if Subordinated Creditor fails to deliver a written notice (the “Purchase Notice”) to Senior Creditors within thirty (30) business days following the occurrence of a Purchase Trigger Event, which Purchase Notice shall (i) be signed by Subordinated Creditor and (ii) state that (A) it is a Purchase Notice delivered pursuant to Section 24 of this Agreement, and (B) Subordinated Creditor is thereby offering to purchase all of the Senior Debt at the Purchase Price set forth in Section 24(d) hereof. The Purchase Notice shall be irrevocable by Subordinated Creditor once received by Senior Creditors. After the expiration of the thirty (30) business day period above, Subordinated Creditor shall not be entitled to send a Purchase Notice until the occurrence of a subsequent Purchase Trigger Event. (b) Notwithstanding the delivery of a Purchase Notice in accordance with the terms hereunder, Senior Agent and Senior Creditors may continue to exercise all of their rights and remedies under the Senior Debt until the close of the Purchase on the Purchase Date (as such terms are defined below), and until the close of the Purchase on the Purchase Date Senior Agent and each Senior Creditor shall not be precluded from taking any action, including commencing judicial proceeding or non-judicial actions to collect or enforce the Senior Debt or foreclose on any collateral for the Senior Debt. For the avoidance of doubt, upon the close of the Purchase, such rights and remedies of Senior Agent and Senior Creditors shall cease. (c) On the date (the “Purchase Date”) specified by Subordinated Creditor in the Purchase Notice (which date shall be not less than thirty (30) days, after the receipt by Senior Creditors of the Purchase Notice), subject to any required approval of any court or other governmental authority then in effect, Senior Creditors shall sell to Subordinated Creditor, and Subordinated Creditor shall purchase from Senior Creditors (the “Purchase”), the aggregate amount of Senior Debt outstanding at the time of purchase at par, on a non-recourse basis; provided that the Senior Debt purchased shall not include any rights of Senior Creditors with respect to indemnification obligations of Borrower arising under the Senior Loan Documents prior to the Purchase Date (the “Surviving Obligations”). (d) Without limiting the obligations of Borrower under the Senior Loan Documents to Senior Creditors with respect to the Surviving Obligations (which shall not be transferred in connection with the Purchase), upon the Purchase Date, Subordinated Creditor shall: (i) as the purchase price (the “Purchase Price”) for all of the Senior Debt, pay to Senior Creditors in cash an amount equal to all outstanding Senior Debt as of the Purchase Date, and (ii) furnish cash collateral to SVB (X) in an amount equal to one hundred five percent (105.0%) of the face amount of all letters of credit issued by Senior Creditor that are denominated in United States Dollars, plus all interest, reasonable and documented fees, and costs due in connection therewith (as determined by Senior Creditor in its good faith business judgment), (Y) in an amount equal to one hundred five percent (105.0%) of the face amount of all letters of credit issued by SVB that are denominated in a currency other than United States Dollars, plus all interest, reasonable and documented fees, and costs due in connection therewith (as estimated by SVB in its good faith business judgment) and (Z) in an amount equal to all Bank Services and any other contingent obligations (all of the foregoing in clause (X), clause (Y) and clause (Z) being “Reimbursement Obligations”), to cash collateralize such Reimbursement Obligations (or make such other arrangements as are acceptable to SVB in its sole discretion to assume any reimbursement obligations relating to such Reimbursement Obligations), and (iii) agree to reimburse Senior Creditors for any loss, cost, damage or reasonable and documented out-of-pocket cost or expense (including reasonable and documented out-of-pocket attorneys’ fees and legal expenses) in connection with any commissions, fees, costs or expenses related to any issued and outstanding letters of credit as described above and any checks or other payments provisionally credited to Senior Creditors and/or as to which Senior Creditors have not yet received final payment. The Purchase Price and cash collateral above shall be remitted by wire transfer in immediately available federal funds to such bank account of Senior Creditors as Senior Creditors may designate in writing to Subordinated Creditor for such purpose. Interest shall be calculated to and including the business day on which the Purchase shall occur if the amounts so paid by Subordinated Creditor to the bank account designated by Senior Creditors are received in such bank account prior to 12:00 p.m., New York City time, and interest shall be calculated to and including the following business day if the amounts so paid by Subordinated Creditor to the bank account designated by Senior Creditors are received in such bank account later than 12:00 p.m., New York City time. Until the Purchase is final and the Senior Debt (other than contingent indemnity obligations) is paid in full, Senior Agent and each Senior Creditor may continue to exercise all of its rights and remedies under the Senior Debt. (e) Such purchase of the Senior Debt shall be made on a non-recourse basis, pursuant to SVB’s standard non-recourse sale and assignment agreement, without representation or warranty by any Senior Creditor as to the Senior Debt, any property serving as the Senior Collateral, or otherwise, except that each Senior Creditor shall represent and warrant: (i) the amount of the Senior Debt being purchased from Senior Creditors; (ii) that such Senior Creditor owns the Senior Debt free and clear of any Lien or encumbrances; and (iii) such Senior Creditor has the right to sell and assign the Senior Debt. 25. ATTORNEYS’ FEES In the event of any legal action to enforce the rights of a party under this Agreement, the party prevailing in such action shall be entitled, in addition to such other relief as may be granted, all reasonable and documented out-of-pocket costs and expenses, including reasonable attorneys’ fees, incurred in such action.

In exchange for the purchase of the Trial Data Package as set forth in Section 11.1.1.4, PB will pay to SFJ, in US Dollars: 6.1.1 following Regulatory Approval by the FDA, an initial payment in the amount set forth below to be made within [***] after the date of the Regulatory Approval by the FDA as shown in the table below (the “Initial US Payment”) and annual payments in the amounts set forth below on or before each applicable anniversary of the date of such Regulatory Approval (collectively but excluding the Initial US Payment, the “US Approval Payments”); 6.1.2 following Regulatory Approval by the EMA, an initial payment in the amount set forth below to be made within [***] after the date of the Regulatory Approval by the EMA (or, as applicable, by the national Regulatory Authority in any Designated European Country) as shown in the table below (the “Initial EU Payment”) and annual payments in the amounts set forth below on or before each applicable anniversary of the date of the such Regulatory Approval (collectively but excluding the Initial EU Payment, the “EU Approval Payments”); and 6.1.3 following Regulatory Approval by the PMDA or the NMPA, an initial payment in the amount set forth below to be made within [***] after the date of first Regulatory Approval by the PMDA or the NMPA as shown in the table below (the “Initial Japan/China Payment”) and annual payments in the amounts set forth below shall be due on each applicable anniversary of the date of such Regulatory Approval (collectively but excluding the Initial Japan/China Payment, the “Japan/China Approval Payments”); provided, in each case, that if conditional Regulatory Approval in a geographic territory specified above in Section 6.1.1, 6.1.2 or 6.1.3 is obtained on the basis of Successful Phase 3 Interim Analysis but unconditional Regulatory Approval is not obtained (i.e., the accelerated Regulatory Approval is withdrawn by the applicable Regulatory Authority) in such geographic territory as a result of failure of the final results of the Phase 3 Trial to meet the Phase 3 Success Criteria or failure of any other human clinical trial that the applicable Regulatory Authority requires PB to conduct after the grant of conditional Regulatory Approval as a condition to the grant of unconditional Regulatory Approval to meet the primary endpoint(s) of such trial and the Product is required to be withdrawn from the market in such geographic territory, then PB shall have no obligation to make any additional Approval Payment for such geographic territory that would otherwise have become due during the period after withdrawal of such conditional Regulatory Approval and before such time (if ever) as Regulatory Approval for such geographic territory is again obtained (and for so long thereafter as such Regulatory Approval remains in effect), provided further that with regard to withdrawal of such conditional Regulatory Approval in [***]. The Initial US Payment, Initial EU Payment, Initial Japan/China Payment, US Approval Payments, EU Approval Payments and Japan/China Approval Payments are collectively referred to as the “Approval Payments”, and shall be subject to adjustment as provided in Section 6.2.

Approval Payment Schedule Upon Approval FDA Approval 5,000,000 EMA Approval 5,000,000 First Approval by either PMDA or NMPA 1,000,000 1yr 2yr 3yr 4yr 5yr 6yr 7yr 8yr Total Anniversary Anniversary Anniversary Anniversary Anniversary Anniversary Anniversary Anniversary [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] [***] 0 0 330,000,000 210,000,000 [***] 60,000,000 Total 11,000,000 [***] [***] [***] [***] [***] [***] [***] [***] 600,000,000 6.2 Payment Adjustments. In the event that the actual Development Costs paid or incurred by SFJ hereunder are lower or greater than One Hundred Twenty Million U.S. Dollars ($120,000,000.00), including by reason of any amount of Going Concern Funding paid by SFJ to PB in accordance with Section 4.2.4, or in the event that such actual Development Costs are subject to adjustment pursuant to Section 2.3.3, Section 3.12.2 and/or Section 3.12.3, the Approval Payments will be multiplied by a fraction, the numerator of which is such actual amount of Development Costs paid or incurred by SFJ hereunder (as adjusted, to the extent applicable, pursuant to Section 2.3.3, Section 3.12.2 and/or Section 3.12.3) and the denominator of which is One Hundred Twenty Million U.S. Dollars ($120,000,000.00). In the event that Regulatory Approval is obtained in a particular jurisdiction while Development Costs for other jurisdiction(s) are still being paid or incurred, in which case the Parties shall recalculate the applicable adjustment at such time as the final amount of actual Development Costs is known and determine any true-up payments required to be made by PB with respect to any payment made pursuant to Section 6.1 prior to such time, and PB shall pay any such true-up payment to SFJ within [***] after receipt of invoice from SFJ. 6.3 Method and Timing of Payment.

PB will provide SFJ with written notice of each wire transfer to SFJ’s account. All amounts payable and calculations under this Agreement shall be in US dollars. 6.4 Late Payments. If PB fails to pay any amount due under this Agreement on the due date therefore, then, without prejudice to any other remedies that SFJ may have, that amount will bear interest from the due date until payment of such amount is made, both before and after any judgment, at a rate equal to, [***] percent ([***]%) per annum computed on the basis of a year of 360 days for the actual number of days payment is delinquent or if such rate exceeds the maximum amount permitted by Applicable Law, at such maximum rate. 6.5 Taxes. The Parties hereby acknowledge and agree that payments made under this Agreement will be made without reduction for withholding or similar taxes, unless such withholding or similar tax is required (x) by a taxing authority as a result of an audit or examination, (y) due to the assignment of this Agreement or any payment obligation hereunder (to the extent permitted) by SFJ to an Affiliate or Third Party, or (z) as a result of a change in Applicable Laws at any time during the Term. In such case, the Parties shall use commercially reasonable and legal efforts to mitigate the amount of such taxes that would need to be withheld and/or paid. Any amounts withheld pursuant to this Section 6.5 will be timely paid over to the appropriate taxing authority, and will be treated for purposes of this Agreement as having been paid to the Party that otherwise would have received such amounts. In the event of a “determination” within the meaning of Section 1313(a) of the Code that withholding or similar taxes were required but were not properly withheld, the Party that received the relevant payment will indemnify and hold the other Party harmless with respect to such taxes and related Losses. 6.6 Tax Cooperation. The Parties will cooperate and produce on a timely basis any tax forms or reports, including any IRS Forms W-8BEN or W-9, as applicable, reasonably requested by the other Party in connection with any payment made under this Agreement.

Each Party will provide to the other Party any tax forms at least [***] prior to the due date for any such payments. Each Party will provide the other with commercially reasonable assistance to enable the recovery, as permitted by law, of withholding taxes, VAT, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or VAT. Each Party will provide commercially reasonable cooperation to the other Party, at the other Party’s expense, in connection with any official or unofficial tax audit or contest relating to tax payments made with respect to amounts paid or payable to such other Party under this Agreement. 6.7 Buy-Out Option. 6.7.1 Approval Buy-Out Option. Within one hundred and twenty (120) days following the receipt of Regulatory Approval with respect to each of the US, Designated European Countries, and Japan/China, PB shall have the right to make a one-time payment (each, an “Approval Buy-Out Payment”) in lieu of all (but not less than all) Approval Payments (as adjusted in accordance with Section 6.2) for the applicable country(ies) (other than the Initial US Payment, Initial EU Payment or Initial Japan/China Payment, as applicable, payable pursuant to Section 6.1 as a result of such Regulatory Approval, in each case, as adjusted in accordance with Section 6.2) by written notice delivered to SFJ no later than [***] after the date of such Regulatory Approval, which written notice shall set forth the amount of the applicable Approval Buy-Out Payment, the proposed date of closing (which shall occur within [***] after the date of the Regulatory Approval), and the calculation of the Approval Buy-Out Payment in reasonable detail based upon the proposed closing date. The Approval Buy-Out Payment will be calculated as follows: [***] Each Approval Buy-Out Payment will be payable in one installment in cash at the closing to an account specified by SFJ. The discount rate used to calculate each Approval Buy-Out Payment shall be [***] percent ([***]%). 6.7.2 Change of Control Buy-Out Option.

To exercise its right to make the Change of Control Buy-Out Payment, PB or its successor shall provide written notice to SFJ (the “Change of Control Buy-Out Notice”) no later than [***] after the date of closing of such Change of Control, which written notice shall set forth the amount of the applicable Change of Control Buy-Out Payment, the proposed date of closing of the buy-out (which shall occur within [***] after the date of closing of such Change of Control), and the calculation of the Change of Control Buy-Out Payment in reasonable detail based upon the proposed closing date of the buy-out. The Change of Control Buy-Out Payment will be calculated as follows: [***] The Change of Control Buy-Out Payment will be payable in one installment in cash at the closing to an account specified by SFJ. The discount rate used to calculate each Change of Control Buy-Out Payment shall be [***] percent ([***]%).

Anything herein to the contrary notwithstanding, in no event shall the SFJ Collateral include, and PB shall not grant and shall not be deemed to have granted a security interest in, (1) any property to the extent that such grant of security interest is prohibited by any Applicable Law of a Governmental Authority or constitutes a breach or default under or results in the termination of or requires any consent not obtained under, any contract, license, agreement, instrument or other document evidencing or giving rise to such property, except to the extent that such Applicable Law or the term in such contract, license, agreement, instrument or other document providing for such prohibition, breach, default or termination or requiring such consent is ineffective under Section 9-406, 9-407, 9-408 or 9-409 of the Uniform Commercial Code in effect in the State of Delaware (or any successor provision or provisions) of any relevant jurisdiction or any other Applicable Law (including bankruptcy or insolvency statutes) or principles of equity; provided, however, that such security interest shall attach immediately at such time as such Applicable Law is not effective or applicable, or such prohibition, breach, default or termination is no longer applicable or is waived, and to the extent severable, shall attach immediately to any portion of the SFJ Collateral that does not result in such consequences or (2) any of PB’s rights, title or interest in any of the outstanding voting capital stock or other ownership interests of a CFC in excess of 65% of the voting power of all classes of capital stock or other ownership interests of CFC entitled to vote. This Agreement shall create a continuing security interest in the SFJ Collateral which shall remain in effect until all PB Obligations (other than contingent indemnity obligations) have been paid or otherwise satisfied in full in accordance with this Agreement and/or, if applicable, the Program Transfer Agreement. Upon payment or other satisfaction of all PB Obligations (other than contingent obligation), SFJ shall, at the sole cost and expense of PB, release its Liens in the SFJ Collateral and all rights therein shall revert to PB. 7.2 Priority of Security Interest. PB represents, warrants and covenants that, subject to fulfilment of PB’s obligations under Section 7.4 and SFJ making any filings necessary to achieve such perfection, the security interest granted to SFJ pursuant to this ARTICLE 7 (the “SFJ Security Interest”) on the Initial Funding Date shall be and shall at all times thereafter continue to be a first-priority perfected security interest in the SFJ Collateral (subject only to the lien of SVB arising under the SVB Loan Agreement, subject in all respects to the terms and conditions of the subordination agreement contemplated by Section 7.4 hereof, and other Permitted Liens that are permitted pursuant to the terms of this Agreement). 7.3 Authorization to File Financing Statements.

Such financing statements may indicate the SFJ Collateral as substantially the same as the SFJ Collateral described in Section 7.1 or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all in SFJ’s reasonable discretion. 7.4 Subordination to SVB Loan. On or before the Initial Funding Date, PB shall negotiate in good faith and enter into a subordination agreement with SVB and SFJ reflecting in all material respects the terms described on Exhibit P attached hereto, pursuant to which SFJ will subordinate to SVB all PB Obligations and all Liens in the SFJ Collateral in favor of SFJ of indebtedness of PB to SVB, which agreement shall (a) limit the aggregate principal amount of indebtedness of PB to SVB that will be senior to SFJ at [***], (b) include a provision pursuant to which in certain circumstances SFJ shall be entitled in its discretion to purchase or repay all obligations (other than contingent indemnity obligations) owing by PB to SVB arising under or in connection with the SVB Loan Agreement in exchange for a release of SVB’s Liens on PB’s assets, (c) include an obligation on the part of SFJ to, in connection with any refinancing or replacement of the SVB Loan Agreement, enter into a new subordination agreement with a new lender(s) on terms and conditions that are taken as a whole not less favorable in any material respect to SFJ than those set forth in the subordination agreement to be entered into with SVB, and (d) otherwise be in form and substance reasonably satisfactory to SFJ. Upon the execution of such new subordination agreement with such new lender(s), references herein to “SVB” shall refer to such new lender(s), references herein to the “SVB Loan” shall refer to the loans provided by such new lender (provided that the aggregate principal amount of such loans shall not exceed [***]), references herein to the “SVB Collateral” shall refer to the collateral securing such new loan, and references herein to the “SVB Loan Agreement” shall refer to such loan and security agreement or similar document entered into with such new lender(s). 7.5 Negative Covenants. 7.5.1 Incurrence of Certain Indebtedness. PB shall not, without SFJ’s prior written consent, create, incur, assume, or be liable for any Indebtedness, or permit any subsidiary of PB to do so, other than Permitted Indebtedness. 7.5.2 Subordinated Debt. PB shall not (a) make or permit any payment on any Subordinated Debt, except to the extent permitted by the terms of the subordination, intercreditor, or other similar agreement to which such Subordinated Debt is subject, or (b) amend any provision in any document relating to Subordinated Debt which would provide for earlier or greater principal, interest, or other cash payments thereon, or materially adversely affect the subordination thereof to PB Obligations owed to SFJ. 7.5.3 Encumbrances. PB shall not, without SFJ’s prior written consent: 7.5.3.1 create, incur, allow, or suffer any Lien on any of the PB Intellectual Property, or assign or convey any right to receive income with respect to the PB Intellectual Property (other than royalty and other license fee obligations to licensors thereof in accordance with the applicable license agreement), including the sale of any PB Intellectual Property, or permit any of its subsidiaries to do so, other than Liens in favor of SVB (subject in all respects to the terms and conditions of the subordination agreement contemplated by Section 7.4 hereof) and other Permitted Liens that are permitted pursuant to the terms of this Agreement; or 7.5.3.2 except as and to the extent permitted by Section 7.5.6, enter into any agreement, document, instrument or other arrangement (except with or in favor of SFJ or SVB) with any Person which directly or indirectly prohibits or has the effect of prohibiting PB or any subsidiary of PB from assigning, mortgaging, pledging, granting a security interest in or upon or encumbering any proceeds from PB Intellectual Property. 7.5.4 Distributions; Investments. PB shall not, without SFJ’s prior written consent, (a) pay any dividends or make any distribution or payment on account of or redeem, retire or purchase any capital stock, provided that (i) PB may convert any of its equity convertible securities into other equity securities (or cash for partial shares) pursuant to the terms of such equity convertible securities or otherwise in exchange thereof, (ii) PB may pay dividends solely in common stock, and (iii) PB may repurchase the stock of former employees or consultants pursuant to stock repurchase agreements, provided that the aggregate amount of all such repurchases does not exceed [***] Dollars ($[***]) per fiscal year; or (b) directly or indirectly make any Prohibited Investment (including, without limitation, by the formation of or through any subsidiary), or permit any of its subsidiaries to do so.

PB shall have the right, without SFJ’s consent, to enter into any Excluded Licensing Transaction. PB shall not, without SFJ’s prior written consent, enter into a Licensing Transaction unless such Licensing Transaction is an Excluded Licensing Transaction (in which case such prohibition shall not apply and no such consent of SFJ shall be required); provided that SFJ shall only be entitled to withhold such consent as to a Licensing Transaction other than an Excluded Licensing Transaction in the event SFJ reasonably determines, and provides PB with written notice of its determination within [***] of PB providing to SFJ a non-binding term sheet or comparable document summarizing the material terms of the proposed Licensing Transaction [***], that PB entering into such Licensing Transaction would [***] (“Material Impact”). If PB disagrees with SFJ’s determination, the matter shall be submitted to arbitration before a single neutral arbitrator under the American Arbitration Association’s (AAA’s) expedited arbitration rules, which arbitrator shall be mutually agreeable to both Parties and have significant expertise on the subject matter to be decided (provided that if the Parties have not mutually agreed on such arbitrator within [***] after the applicable demand for arbitration, the AAA shall designate such arbitrator), such arbitration to be concluded and the arbitrator’s award to be rendered within [***] of the applicable demand for arbitration. The sole issue to be decided in the arbitration shall be whether the entry into such Licensing Transaction by PB would have a substantial likelihood of having a Material Impact.

PB shall not, from and after the Effective Date, enter into any agreement that prohibits or limits the ability of PB to create, incur, assume or suffer to exist any Lien upon any PB Intellectual Property (including any Accounts with respect to such royalties or license fees), whether now owned or hereafter acquired, to secure the PB Obligations, other than (a) agreements with SFJ (including this Agreement), (b) any agreements governing purchase money Liens or capital lease obligations otherwise permitted hereby (in which case, any such prohibition or limitation shall only be effective on the assets financed thereby), (c) customary restrictions on assignment contained in leases, licenses or other agreements or (d) the SVB Loan Agreement and any loan documents entered into in connection therewith. 7.6 Affirmative Covenants.

PB represents and warrants to SFJ that, as of the Effective Date, it maintains no Collateral Accounts other than the Collateral Accounts described on Schedule 7.6.1.1(b) to the Disclosure Letter. In addition to and without limiting the foregoing, PB shall provide SFJ with [***] prior written notice before establishing any additional Collateral Account at or with any bank or financial institution.

PB shall comply, and shall cause each subsidiary to comply, in all material respects, with all laws, ordinances and regulations to which it is subject noncompliance with which would reasonably be expected to have a material adverse effect on PB’s business.

PB shall use Commercially Reasonable Efforts in the exercise of its business judgment to prosecute, protect, defend and maintain the validity and enforceability of the PB Intellectual Property. 7.6.5 Acceleration. In the event that, following an applicable Regulatory Approval, PB shall fail to make any Approval Payment associated with such Regulatory Approval within [***] of the due date therefor in accordance with ARTICLE 6, all remaining unpaid Approval Payments that are based on such Regulatory Approval shall become immediately due and payable; provided that, in the event of any such acceleration, SFJ’s rights to receive such Approval Payments, if any, shall be adjusted as set forth in Section 6.2 and reduced by any amounts previously paid to SFJ. 7.7 Certain Defined Terms.

The foregoing obligations will not apply to any portion of such information or materials that the Receiving Party can demonstrate: 10.1.1 was publicly disclosed by the Disclosing Party before or after such Confidential Information becomes known to the Receiving Party; 10.1.2 was already known to the Receiving Party or any of its Affiliates, other than under an obligation of confidentiality or non-use, prior to when it was received from the Disclosing Party; 10.1.3 is subsequently disclosed to the Receiving Party or any of its Affiliates by a Third Party lawfully in possession thereof without obligation to keep such Confidential Information confidential; 10.1.4 has been published by a Third Party or otherwise enters the public domain through no fault of the Receiving Party or any of its Affiliates in breach of this Agreement; or 10.1.5 has been independently developed by the Receiving Party or any of its Affiliates, without the aid, application or use of any Confidential Information of the other Party. 10.2 Authorized Disclosure. Each Party may disclose Confidential Information belonging to the other Party to the extent such disclosure is reasonably necessary for complying with Applicable Laws, including regulations promulgated by securities exchanges, provided that the Party required to disclose such information promptly notifies the Disclosing Party prior to making any such disclosure and cooperates with the Disclosing Party’s efforts to seek confidential treatment or to otherwise limit disclosure. Each Receiving Party may disclose the other Party’s Confidential Information to its Affiliates, employees, agents, advisors, and independent contractors (including Permitted Third Parties) engaged by such Receiving Party, in each case (a) only to the extent such Persons need to know the Confidential Information solely in connection with the performance of this Agreement or, if applicable, the Program Transfer Agreement and (b) provided that each Person receiving Confidential Information must be bound by obligations of confidentiality and non-use at least as stringent as an equivalent in scope to those set forth in this ARTICLE 10 prior to any such disclosure and the Party making such disclosure to such Person shall be liable to the other Party for any breach of such obligations by such disclosee. PB may disclose SFJ Confidential Information to MedImmune as necessary to comply with PB’s obligations or exercise PB’s rights under the AZ License (it being understood that any such disclosure will be made under the terms of Article 6 of the AZ License and that PB shall not be required to enter into any further confidentiality agreement with MedImmune for such purpose). Each Party may also disclose the material terms of this Agreement (including the form of Program Transfer Agreement) or provide a copy of this Agreement or a summary of such Party’s findings during its due diligence investigation of the Products (if applicable) to any bona fide potential or actual investor, investment banker, acquirer, provider of debt or royalty financing, or other potential or actual financial partner without consent of the other Party, and provided that in connection with such disclosure, each disclosee must be bound by obligations of confidentiality and non-use at least as stringent as an equivalent in scope to those set forth in this ARTICLE 10 prior to any such disclosure and the Party making such disclosure to such disclosee shall be liable to the other Party for any breach of such obligations by such disclosee.

Except as otherwise provided herein, upon expiration or earlier termination of this Agreement, all Confidential Information (including any copies thereof) in written or other tangible form will, at the Disclosing Party’s direction, be returned to the Disclosing Party or destroyed by the Receiving Party, and any Person(s) to whom the Receiving Party disclosed (with such destruction being certified in writing by an authorized officer of the Receiving Party), except (i) to the extent such Confidential Information is necessary to exercise any license and/or rights hereunder that survive such expiration or earlier termination; and (ii) one (1) copy of each document may be retained by the Receiving Party solely to the extent necessary to permit it to comply with any ongoing rights and responsibilities with respect to such Confidential Information. 10.4 MedImmune Confidential Information. With respect to any Confidential Information of PB that constitutes MedImmune Confidential Information, SFJ hereby agrees to be bound by the provisions of Sections 6.1, 6.2 and 6.7 of the AZ License to the same extent as PB is. 10.5 Confidential Status of the Agreement. Subject to Section 10.2 and Section 10.6, the terms of this Agreement, including the form of Program Transfer Agreement (whether or not executed by the Parties), are deemed to be Confidential Information and will be subject to the confidentiality requirements of this ARTICLE 10, with each Party being deemed a Receiving Party for such purposes. The Parties each acknowledge that it will be necessary for PB to file this Agreement with the US Securities and Exchange Commission and to make other required public disclosures regarding the terms of this Agreement, and accordingly PB shall prepare a confidential treatment request in connection with such filing and provide SFJ a reasonable opportunity to review and comment on such filing as well as on such other required public disclosures and thereafter use Commercially Reasonable Efforts to obtain confidential treatment as to the terms of this Agreement. 10.6 Publicity. The Parties recognize that following the Effective Date the Parties (either individually or jointly) shall issue mutually agreed press release(s) announcing the execution of this Agreement, and thereafter each Party may from time to time desire to issue additional press releases and make other public statements or disclosures regarding the subject matter of this Agreement, and hereby agree that such additional press releases, public statements and disclosures regarding the terms of this Agreement will be permitted only with the other Party’s written consent (which shall not be unreasonably withheld, conditioned or delayed). Any publication, news release or other public announcement relating to the terms of this Agreement will first be reviewed and approved in writing by both Parties; provided, however, that any disclosure of the minimum information which is required by Applicable Law (including the rules of a securities exchange), as reasonably advised by the disclosing Party’s counsel, may be made without the prior consent of the other Party, although the other Party will be given prompt notice of any such legally required disclosure and to the extent practicable will be provided an opportunity to comment on the proposed disclosure and the disclosing Party will consider in good faith any comments provided by the other Party on such proposed disclosure. For avoidance of doubt, this Section 10.6 shall not restrict PB from releasing public statements or disclosures regarding PB’s development and Commercialization activities with respect to the Product. 10.7 Use of Name. Unless otherwise expressly permitted herein, PB will obtain the written consent of SFJ (which consent will not unreasonably be withheld, conditioned or delayed) prior to referring to SFJ in any correspondence with any Regulatory Authority or Governmental Authority, except as may be required by Applicable Law.

In addition, PB shall be and remain the sole and exclusive owner of all right, title and interest in and to all PB Intellectual Property arising during the term of this Agreement independent of the conduct of the activities contemplated by this Agreement.

If (i) SFJ is unable to cause any such Third Party contractor or consultant (including any contractor who is, or a consultant who is employed by, a governmental, not-for-profit, or public institution that has standard policies against such an assignment) to agree to such assignment obligation with respect to AstraZeneca Product Improvements despite SFJ’s using commercially reasonable efforts to negotiate such assignment obligation, or (ii) Applicable Law would prohibit SFJ from requiring such an assignment from such Third Party contractor or consultant, in each case ((i) and (ii)), SFJ and its Affiliates shall refrain from using such Third Party contractor or consultant to conduct activities pursuant to this Agreement unless PB obtains MedImmune’s written consent thereto. Agreement and the terms of the AZ License, in each case, as applicable to AstraZeneca Product Improvements, AstraZeneca Product Know-How or AstraZeneca Product Patents, the terms of the AZ License shall prevail.

SFJ, for itself and on behalf of its Affiliates, hereby assigns, and shall cause such other Permitted Third Parties to assign (subject to Section 11.1.1.3(c)), to PB all its right, title and interest in and to Trial Inventions and all information and data necessary to support the filing of patent applications Covering such Trial Inventions. SFJ will cooperate, and will cause the foregoing Persons to cooperate, with PB to effectuate and perfect the foregoing ownership, including by promptly executing and recording assignments and other documents consistent with such ownership.

In the case of any individual consultant of SFJ or its Affiliates (excluding SFJ’s and its Affiliates’ Permitted Third Parties), if SFJ is unable to cause such consultant to agree to such assignment obligation despite SFJ’s using commercially reasonable efforts to negotiate such assignment obligation, then SFJ shall either: (A) cause such consultant to grant an exclusive, worldwide, royalty-free, fully-paid, freely-assignable license, with the right to sublicense through multiple tiers, under their rights in such Trial Invention to develop, make, have made, use, sell, have sold, offer for sale and import the Product for any and all uses, except where Applicable Law requires otherwise and except in the case of consultants who are employed by governmental, not-for-profit, or public institutions that have standard policies against such an assignment (in which case, SFJ shall use commercially reasonable efforts to obtain a suitable license, or right to obtain such a license); or (B) refrain from using such consultant to conduct activities pursuant to this Agreement unless PB obtains MedImmune’s written consent thereto.

At PB’s request and expense (for reasonable out-of-pocket expenses), SFJ will reasonably cooperate with PB in preparing, filing, prosecuting, and maintaining such Patents. 11.3 Intellectual Property Enforcement. 11.3.1 PB Intellectual Property. PB will use Commercially Reasonable Efforts to enforce Intellectual Property Controlled by PB, including Intellectual Property that covers the Trial Inventions, against Third Party Infringements. 11.3.2 Infringement of Third Party Rights. If either Party learns of Third Party allegations that it or the other Party or any of its or the other Party’s Affiliates or Permitted Third Parties, have infringed, misappropriated or otherwise violated, or are infringing, misappropriating or otherwise violating, any Intellectual Property of a Third Party in connection with either the Clinical Trials or performing its obligations or duties hereunder, such Party will promptly notify the other Party.

ARTICLE 12 INDEMNIFICATION AND INSURANCE 12.1 Indemnification by Each Party. 12.1.1 By SFJ. SFJ will indemnify and hold PB; its Affiliates and their respective officers, directors, employees and agents (the “PB Indemnified Parties”), harmless from any and all Losses, net of any related tax benefit actually realized in the same year as the payment or incurrence of such Losses or any prior year, arising or resulting from any Claims by a Third Party against any PB Indemnified Parties to the extent arising from (a) the gross negligence or willful misconduct of SFJ or any of its Affiliates or any of its or their respective Permitted Third Parties in performing SFJ’s obligations under this Agreement or, if applicable, the Program Transfer Agreement; (b) SFJ’s material breach of this Agreement or, if applicable, the Program Transfer Agreement; (c) any material breach of a Protocol by SFJ, or its Affiliate, or any of its or their respective Permitted Third Parties; (d) any breach by SFJ of any provision of the AZ License by which SFJ has agreed to be bound in this Agreement; (e) a physical injury or death of a subject that is caused by the subject’s participation in any clinical trial conducted by or on behalf of SFJ or any of its Affiliates after a Program Transfer whether or not directly attributable to the Product(other than the Product manufactured by PB); and/or (f) from any after any Program Transfer, product liability claims resulting from the Commercialization of Product other than Product manufactured by PB by or on behalf of SFJ or any of its Affiliates, licensees or sublicensees; except to the extent that any of the foregoing (a) through (f) was caused by (i) the gross negligence or willful misconduct of any PB Indemnified Party, or (ii) material breach of this Agreement, or, if applicable, the Program Transfer Agreement, by PB. 12.1.2 By PB. PB will indemnify and hold SFJ, its Affiliates, SFJ’s investors and their respective officers, directors, employees and agents (the “SFJ Indemnified Parties”), harmless from any and all Losses, net of any related tax benefit actually realized in the same year as the payment or incurrence of such Losses or any prior year, arising or resulting from any Claims by a Third Party against any SFJ Indemnified Parties to the extent arising from (a) a Product supplied by PB; (b) a physical injury or death of a Subject that is caused by the Subject’s participation in the Clinical Trials whether or not directly attributable to the Product (excluding any Clinical Trial conducted by or on behalf of SFJ or its Affiliate after a Program Transfer); (c) PB’s gross negligence or willful misconduct in performing its obligations under this Agreement or, if applicable, the Program Transfer Agreement; (d) PB’s material breach of this Agreement or, if applicable, the Program Transfer Agreement, (e) any material breach of a Protocol by PB, or its Affiliate, or of its or their respective Permitted Third Parties, (f) actual or alleged infringement of any Third Party’s Intellectual Property by the Product or by either Party in performing its duties or obligations hereunder with respect to the Product; and (g) injuries sustained by Subjects in connection with the Clinical Trials, including Claims arising prior to the Effective Date based upon physical injury or death of a Subject in connection with the Clinical Trials, or from the Commercialization of the Product; except to the extent that any of the foregoing (a) through (g) were caused by (i) the gross negligence or willful misconduct of any SFJ Indemnified Party, or (ii) material breach of this Agreement, or, if applicable, the Program Transfer Agreement by, SFJ. 12.2 Indemnification Procedure. 12.2.1 Notice of Claim. A Party believing that it is entitled to indemnification under Section 12.1.1 or 12.1.2 (an “Indemnified Party”) will give prompt written notice (each, an “Indemnification Claim Notice”) to the other Party (the “Indemnifying Party”) upon receipt of notice of the commencement of any Claim for which indemnification may be sought, or if earlier, upon the assertion of any such Claim by a Third Party (it being understood and agreed, however, that the failure by an Indemnified Party to give notice of a Claim of a Third Party as provided in this Section 12.2.1 will not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually prejudiced as a result of such failure to give notice). Each Indemnification Claim Notice will contain a description of the Claim and the nature and amount of the Loss (to the extent that the nature and amount of such Loss are known at such time). The Indemnified Party will furnish promptly to the Indemnifying Party copies of all papers and official documents received in respect of any Losses. 12.2.2 Control of Defense. At its option, the Indemnifying Party may assume the defense of any Claim by giving written notice to the Indemnified Party within [***] after the Indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Claim by the Indemnifying Party will not be construed as an acknowledgment that the Indemnifying Party is liable to indemnify the Indemnified Party in respect of the Claim, nor will it constitute a waiver by the Indemnifying Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. Upon assuming the defense of a Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Claim any legal counsel selected by the Indemnifying Party that is reasonably satisfactory to the Indemnified Party. In the event the Indemnifying Party assumes the defense of a Claim, the Indemnified Party will promptly deliver to the Indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection with the Claim. Should the Indemnifying Party assume the defense of a Claim, the Indemnifying Party will not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of such Claim. 12.2.3 Right to Participate in Defense. Without limiting Section 12.2.2, the Indemnified Party will be entitled to (a) participate in, but not control, the defense of such Claim and to engage counsel of its choice for such purpose; provided, however, that such engagement will be at the Indemnified Party’s own expense unless the engagement thereof has been specifically authorized by the Indemnifying Party in writing, and (b) control its defense of such Claim and to engage counsel of its choice for such purpose, at the expense of the Indemnifying Party, if the Indemnifying Party has failed to assume the defense and engage counsel in accordance with Section 12.2.2. 12.2.4 Settlement. With respect to any Losses related solely to payment of money damages in connection with a Claim and that includes a complete and unconditional release of the Indemnified Party, will not result in the Indemnified Party admitting liability, becoming subject to injunctive or other equitable relief that will otherwise adversely affect the business of the Indemnified Party in any manner, and as to which the Indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the Indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the Indemnifying Party, in its sole discretion, will deem appropriate. With respect to all other Losses in connection with Claims, where the Indemnifying Party has assumed the defense of the Claim in accordance with Section 12.2.2, the Indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld, conditioned or delayed). The Indemnifying Party will not be liable for any settlement or other disposition of a Loss by the Indemnified Party that is reached without the written consent of the Indemnifying Party (which consent will not be unreasonably withheld, conditioned or delayed). Regardless of whether the Indemnifying Party chooses to defend or prosecute any Claim, the Indemnified Party will not admit any liability with respect to, or settle, compromise or discharge, any Claim without the prior written consent of the Indemnifying Party, not to be unreasonably withheld or delayed. 12.2.5 Cooperation. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Claim, the Indemnified Party will reasonably cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation will include access during normal business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Claim, and making employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the Indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith. 12.3 Insurance. 12.3.1 Generally. Commencing as of the Effective Date and thereafter during the Development Term, and subject to Section 12.3.2 below, each Party will carry and maintain, at its own expense, insurance coverage of the kind and with liability limits that, at a minimum, satisfy the requirements of Section 12.3.2, to protect itself and the other Party against any claims or liabilities that may arise from the conduct of the Clinical Trials and all other rights and obligations hereunder with insurers with a minimum “A-” A.M. Best rating. Any deductibles for such insurance policies will be assumed by the insuring Party. Such insurance policies will be primary and non-contributing with respect to any other similar insurance policies available to other Party and their Affiliates. Prior to the Effective Date, and annually, at each anniversary of the Effective Date (unless, during such year, expiration of the applicable policy occurs first, in which case, on such expiration date), at a Party’s written request the other Party will supply documentation of such insurance coverage via original certificates of insurance, if applicable. Each Party will provide the other Party a minimum of [***] prior written notice if it is unable to obtain appropriate insurance coverage or if its coverage is canceled, unable to be renewed or materially changed. For clarity, any insurance coverage or the failure to maintain adequate insurance coverage does not limit or reduce a Party’s liability under this Agreement. Each Party will ensure that no subcontractor, including any Permitted Third Party, will continue to perform the work unless such subcontractor is insured as deemed appropriate by the Party engaging the Permitted Third Party. 12.3.2 Minimum Requirements. Commencing as of the start of the Clinical Trials and thereafter, during the Term (or longer if otherwise stated below), at a minimum, each Party will maintain the following types of insurance coverage at a minimum level that is the greater of (a) the highest minimum level required by Applicable Law in the countries in which the Clinical Trials and other obligations hereunder are being performed or (b) the following (to the extent different). 12.3.2.1 Commercial General Liability: [***] dollars ($[***]) per occurrence; [***] dollars ($[***]) Product and Completed Operations aggregate, including Premises & Operations, Personal Injury, Product and Completed Operations; [***] dollars ($[***]) combined single limit on all owned, non-owned and hired vehicles of such Party. 12.3.2.2 Umbrella Excess Liability: [***] dollars ($[***]) per occurrence. 12.3.2.3 Clinical Trials Liability: [***] dollars ($[***]) per occurrence. PB will obtain such Clinical Trials Liability insurance on a global basis, and, if required, supplemented Clinical Trials Liability Insurance in the US, at its expense and SFJ will obtain supplemental Clinical Trials Liability insurance for the SFJ Territory and on a country specific basis in the European Clinical Trial Countries as required by Applicable Law at its expense, which will be considered Development Costs. Coverage must be maintained for as long as required by Applicable Law in each country after release of the last Subject from the Clinical Trials or where there is no legal requirement at least [***] after the termination of this Agreement. 12.3.2.4 Professional Liability: Any subcontractor, including any Permitted Third Party, who provides professional services to such Party for the Clinical Trials, will obtain Professional Liability Insurance in lieu of Clinical Trial Insurance, with a minimum limit of [***] dollars ($[***]) per occurrence. Coverage must be maintained for at least [***] after the later of (i) expiration or early termination of this Agreement and (ii) release of the last Subject from the Clinical Trials. 12.3.3 Additional Insured. Each Party will include the other Party and its Affiliates as additional insured parties on such Party’s Clinical Trial Liability insurance, as set forth in Section 12.3.2.3 for [***] after the later of termination of this Agreement or release of the last Subject from the Clinical Trials. 12.3.4 Product Liability Insurance. Prior to a Program Transfer, PB will be responsible for maintaining product liability insurance related to the Development and Commercialization of the Product at its expense with SFJ to be named as an additional insured party. From and after a Program Transfer, SFJ will be responsible for maintaining product liability insurance related to the Development and Commercialization of the Product at its expense with PB to be named as an additional insured party.

Notwithstanding the foregoing, no matters relating to breach or alleged breach of the ownership of intellectual property or rights in intellectual property or the validity or enforceability thereof shall be resolved by arbitration, but rather shall be determined by a U.S. federal court of appropriate jurisdiction. Notwithstanding the foregoing, any dispute between the Parties as to whether entering into a Licensing Transaction would have a Material Impact shall be resolved as set forth in Section 7.5.5. Notwithstanding anything in this Agreement to the contrary, either Party shall be entitled to seek preliminary injunctive relief in any court of competent jurisdiction immediately if necessary to prevent irreparable harm to that Party. 15.10.2 Arbitration Process. 15.10.2.1 Either Party shall have the right to initiate arbitration at any time after the expiration of thirty (30) days after a Dispute is notified to the Executive Officers. Any disputes concerning the propriety of the commencement of the arbitration shall be finally settled by the arbitral tribunal. 15.10.2.2 Any Dispute including the determination of the scope or applicability of this agreement to arbitrate, shall be determined by the ICDR in accordance with its International Arbitration Rules, except as they may be modified herein. The seat, or legal place, of arbitration shall be New York, and the language of the arbitration shall be English. References herein to any arbitration rules or procedures mean such rules or procedures as amended from time to time, including any successor rules or procedures, and references herein to the ICDR include any successor thereto. The arbitration shall be before a tribunal comprised of three (3) arbitrators. Each Party shall select one arbitrator and within fifteen (15) days of the second arbitrator’s appointment, the two (2) Party appointed arbitrators shall select the third, who shall serve as the tribunal’s chair or president. All three (3) arbitrators shall be professionals with substantial experience in development and Commercialization of biopharmaceutical products. An arbitrator shall be deemed to meet these qualifications unless a Party objects within fifteen (15) after the arbitrator is appointed. This arbitration provision, and the arbitration itself, shall be governed by the Federal Arbitration Act, 9 U.S.C. §§ 1 et. seq. 15.10.2.3 Consistent with the expedited nature of arbitration, each Party will, upon the written request of the other Party, promptly provide the other with copies of documents on which the producing Party may rely in support of or in opposition to any claim or defense. At the request of a Party, the arbitrators shall have the discretion to order examination by deposition of witnesses to the extent the arbitrator deems such additional discovery relevant and appropriate. [***]. All objections are reserved for the arbitration hearing except for objections based on privilege and proprietary or confidential information. [***]. Any Dispute regarding discovery, or the relevance or scope thereof, shall be determined by the arbitrators, which determination shall be conclusive. All discovery shall be completed within [***] following the appointment of the arbitrators. All costs and/or fees relating to the retrieval, review and production of electronic discovery shall be paid by the Party requesting such discovery. 15.10.2.4 The arbitrators shall have no authority to award punitive or other damages not measured by the prevailing Party’s actual damages, except as may be required by statute. Each Party expressly waives and foregoes any right to consequential, punitive, special, exemplary or similar damages or lost profits. The arbitrators shall have no power or authority, under the ICDR rules and procedures or otherwise, to relieve the Parties from their agreement hereunder to arbitrate or otherwise to amend or disregard any provision of this Agreement. The cost of the arbitration, including the fees of the arbitrators and reasonable attorney’s fees of the prevailing Party, shall be borne by the Party the arbitrator determines has not prevailed in the arbitration. 15.10.2.5 If an arbitral award does not impose an injunction on the losing Party or contain a money damages award in excess of [***] dollars USD ($[***]), then the arbitral award shall be final and binding and shall only be subject to such challenges as would otherwise be permissible under the Federal Arbitration Act, 9 U.S.C. § 1 et. seq. . Judgment on such an award may be entered in any court of competent jurisdiction and the Parties undertake to carry out the award without delay. In the event that an arbitral award imposes an injunction or contains a monetary award in excess of [***] dollars USD ($[***]), the Parties agree that such award may be appealed pursuant to the AAA’s Optional Appellate Arbitration Rules (“Appellate Rules”) and should not be considered to be final and binding until after the time for filing the notice of appeal under the Appellate Rules has expired. Appeals must be initiated within [***] of receipt of the award, as defined by the Appellate Rules, by filing a Notice of Appeal within any AAA office. Following the appeal process, the decision rendered by the appeal tribunal shall be final and binding and judgment on that award may be entered in any court of competent jurisdiction and the Parties undertake to carry out the award without delay. 15.10.2.6 Except as may be required by law, or to protect or pursue a legal right to enforce or challenge an award in legal proceedings, where needed for the preparation or presentation of a claim or defense in this arbitration, or by order of the arbitral tribunal upon application of a Party, neither a Party nor an arbitrator may disclose the existence, content, or results of any arbitration hereunder without the prior written consent of both Parties. 15.11 Limitation of Liability.

THE PARTIES AGREE THAT THE LIMITATIONS SPECIFIED IN THIS SECTION 15.11 WILL APPLY EVEN IF ANY LIMITED REMEDY SPECIFIED IN THIS AGREEMENT IS FOUND TO HAVE FAILED OF ITS ESSENTIAL PURPOSE. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, “CONSEQUENTIAL DAMAGES” WILL BE DEEMED TO INCLUDE, AND NEITHER PARTY WILL BE LIABLE TO THE OTHER PARTY OR ANY OF SUCH OTHER PARTY’S AFFILIATES, REPRESENTATIVES OR STOCKHOLDERS FOR ANY DAMAGES BASED ON OR MEASURED BY LOSS OF PROJECTED OR SPECULATIVE FUTURE SALES OF THE PRODUCT, ANY PAYMENT DUE UPON ANY UNACHIEVED EVENT UNDER ARTICLE 6, OR ANY OTHER UNEARNED, SPECULATIVE OR OTHERWISE CONTINGENT PAYMENTS PROVIDED FOR IN THIS AGREEMENT.

PROGRAM TRANSFER AGREEMENT THIS PROGRAM TRANSFER AGREEMENT (this “Agreement”) is made and entered into as of [insert date that the Program Transfer Notice is delivered to PB], by and among PhaseBio Pharmaceuticals Inc., a Delaware corporation (“PB”), and SFJ Pharmaceuticals X, Ltd., a Cayman Islands company (“SFJ”). Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in (i) the Co‑Development Agreement dated as of January 9, 2020 between PB and SFJ (the “Co‑Development Agreement”) or (ii) if not defined in the Co-Development Agreement, the AZ License. WHEREAS, pursuant to Section 3.20 of the Co‑Development Agreement, SFJ delivered the Program Transfer Notice to PB, whereupon PB became obligated to cause PB’s business related to the Product to be transferred to SFJ in accordance with Section 1 of this Agreement, on the terms and subject to the conditions set forth in this Agreement (the “Program Transfer”). NOW, THEREFORE, the parties hereto agree as follows: 1. Program Transfer. 1.1 Assignments. Effective upon delivery of the Program Transfer Notice to PB: SFJ shall, and it hereby does, assume the AZ License and all of PB’s rights and obligations thereunder. (a) PB shall, and it hereby does, assign to SFJ the AZ License and all of PB’s rights and obligations thereunder, and (b) PB shall, and it hereby does, assign to SFJ each Licensing Transaction Agreement that is then in effect and all of PB’s rights and obligations thereunder, and SFJ shall, and it hereby does, assume each such Licensing Transaction Agreement and all of PB’s rights and obligations thereunder. 1.2 Within [***] after delivery of the Program Transfer Notice to PB, PB shall provide written notice to MedImmune of the assignment to SFJ of the AZ License in accordance with the terms of the AZ License and written notice to each counterparty to a Licensing Transaction Agreement assigned to SFJ of the assignment to SFJ of such Licensing Transaction Agreement. 1.3 Effective upon delivery of the Program Transfer Notice to PB, PB shall, and it hereby does, and shall cause its Affiliates to, effective upon delivery of the Program Transfer Notice: (a) grant to SFJ an exclusive, perpetual, royalty-free (except to the extent set forth in Section 2) license, with the right to grant multiple tiers of sublicenses, under the Licensee Termination Know-How, Licensee Termination Patents, and PB’s interest in Joint Inventions and Joint Patents to Exploit and Manufacture in the “Territory” (as defined in the AZ License) any Licensed Compound or Licensed Product and grant to SFJ an exclusive perpetual, worldwide, royalty free (except to the extent set forth in Section 2) license, with the right to grant multiple tiers of sublicense, under the PB Intellectual Property and PB Confidential Information to Develop and Commercialize the Product, provided that SFJ is not granted any license in this Agreement with respect to any active pharmaceutical ingredient other than a Licensed Compound. Notwithstanding the exclusivity of the foregoing license, PB hereby reserves the non-exclusive right under the Licensee Termination Know-How, Licensee Termination Patents, PB’s interest in Joint Inventions and Joint Patents, the PB Intellectual Property and PB Confidential Information, to make and have made Licensed Compound and Licensed Product as necessary to perform PB’s obligation to supply or have supplied the Licensed Compounds and Licensed Products to SFJ as set forth in Section 1.9; and (b) assign to SFJ all of PB’s right, title and interest in and to (i) each Product Trademark and (ii) all Regulatory Documentation (including any Regulatory Approvals and Licensee Regulatory Documentation) and the Clinical Trials Database, Clinical Trials Master File, and Case Report Forms applicable to any Licensed Compound or Licensed Product then owned or Controlled by PB or any of its Affiliates, subject, in each case, to SFJ’s royalty payment obligations under Section 2; provided that if any such Regulatory Documentation is not immediately transferable in a country, PB shall provide SFJ with all benefit of such Regulatory Documentation and such assistance and cooperation as necessary or reasonably requested by SFJ to timely transfer such Regulatory Documentation to SFJ or its designee or, at SFJ’s option, to enable SFJ to obtain a substitute for such Regulatory Documentation without disruption to SFJ’s Exploitation or Manufacture of the applicable Licensed Compound(s) or Licensed Product(s). For the avoidance of doubt and notwithstanding anything else in the Co-Development Agreement or this Agreement to the contrary, in the event of Program Transfer SFJ shall not assign or transfer to PB and shall retain all right, title and interest to the Trial Data Package and the Product Filings notwithstanding any Approval Payments which may be made to SFJ, and if the Trial Data Package and the Product Filings have been assigned or transferred to PB, PB shall reassign and transfer the Trial Data Package and the Product Filings to SFJ. 1.4 Effective upon delivery of the Program Transfer Notice to PB, all Confidential Information of PB to the extent relating specifically to any Licensed Compound or Licensed Product or the Exploitation thereof shall thereafter be deemed Confidential Information of SFJ (provided that, for clarity in the case of Confidential Information consisting of PhaseBio Know-How that has uses or application to retained products or technology of PB, this Section 1.4 is not intended to cause such PhaseBio Know-How to constitute Confidential Information of SFJ for purposes of use or application of such Confidential Information relating to such retained products or technologies). 1.5 Notwithstanding any other provision of this Section 1 to the contrary, to the extent the Licensee Termination Patents include any Patent licensed to PB or its Affiliate by a Third Party (other than MedImmune) that is subject to royalty or milestone payment obligations to such Third Party with respect to the Product, then PB shall so notify SFJ within [***] after delivery of the Program Transfer Notice to PB, which notice shall include a true, complete and correct description of such royalty and milestone payment obligations and a correct and complete copy of such Third Party agreement, and the continued inclusion of such Patent in the Licensee Termination Patents licensed to SFJ under Section 1.3(a) shall be subject to SFJ’s agreeing, in writing in accordance with this Section 1.5, to pay all royalty and milestone payments that become due to such Third Party by reason of the Exploitation of the Product by or on behalf of PB or any of its Affiliates or (sub)licensees. SFJ shall pay such amounts in accordance with the terms and conditions of the applicable Third Party agreement, unless SFJ declines or terminates such sublicense rights in accordance with this Section 1.5. Within [***] of SFJ’s receipt of such notice regarding any such Third Party agreement, SFJ shall have the right, upon written notice to PB, to decline any sublicense under such Third Party agreement, in which case SFJ will be deemed not to have received license rights under any such Third Party agreement as of the delivery of the Program Transfer Notice to PB. If SFJ does not decline any such Third Party agreement within such [***] period, SFJ shall have the right in its sole discretion to terminate the sublicense under such Third Party agreement at any time following such [***] period. For clarity, any such Third Party royalty obligations described in this Section 1.5 are in addition to the royalties payable by SFJ to PB for the licenses granted and assignments made by PB pursuant to the first sentence of Section 1.3(a) and pursuant to Sections 1.3(b) and 1.6. 1.6 PB shall and hereby does, and shall cause its Affiliates to, effective as of delivery of the Program Transfer Notice to PB, grant SFJ an exclusive, royalty-free (except as set forth in Section 2) right of reference, with the right to grant multiple tiers of further rights of reference, in and to all Regulatory Documentation (including any Regulatory Approvals) then owned or Controlled by PB or any of its Affiliates that are not assigned to SFJ pursuant to Section 1.3(b) above to Exploit and Manufacture in the “Territory” (as defined in the AZ License) any Licensed Compound or Licensed Product. 1.7 PB shall provide to SFJ a list of all clinical studies ongoing with respect to any Licensed Compound or Licensed Product and, unless expressly prohibited by any Regulatory Authority, at SFJ’s written request and election in SFJ’s sole discretion, PB shall and hereby does, and shall cause its Affiliates to either: (i) wind down in accordance with Applicable Law and observing applicable ethical and regulatory guidelines any or all clinical studies involving Licensed Products being conducted by or on behalf of PB or its Affiliate (but not by any counterparty to a Licensing Transaction Agreement assigned to SFJ pursuant to Section 1.1(b)) as of the date of delivery of the Program Transfer Notice to PB, at PB’s cost and expense; or (ii) (x) transfer control to SFJ of any or all clinical studies involving Licensed Products being conducted by or on behalf of PB or its Affiliate (but not by any counterparty to a Licensing Transaction Agreement assigned to SFJ pursuant to Section 1.1(b)) as of the date of delivery of the Program Transfer Notice to PB and (y) continue to conduct such clinical studies involving Licensed Products being conducted by or on behalf of PB or an Affiliate (but not by any counterparty to a Licensing Transaction Agreement assigned to SFJ pursuant to Section 1.1(b)) as of the date of delivery of the Program Transfer Notice to PB for up to six (6) months to enable such transfer to be completed without interruption of any such clinical study, in each case ((x) and (y)), at SFJ’s cost and expense; provided that SFJ shall not have any obligation to continue any clinical study for which it has elected to have control transferred to SFJ unless required by Applicable Law. 1.8 Following good faith discussions by the Parties as to which Licensed Product Agreements should be assigned to SFJ, at SFJ’s written request, PB shall, and shall cause its Affiliates to, assign to SFJ or its designee any and all Licensed Product Agreements, unless, with respect to any such Licensed Product Agreement, such Licensed Product Agreement (a) expressly prohibits such assignment (in which case, PB or its Affiliate, as applicable, shall cooperate with SFJ in all reasonable respects to secure the consent of the applicable Third Party to such assignment), or (b) relates both to Licensed Products and products other than Licensed Products (in which case, at SFJ’s request, PB or its Affiliate, as applicable, shall cooperate with SFJ in all reasonable respects to secure the written agreement of the applicable Third Party to a partial assignment of the applicable Licensed Product Agreement relating to the Licensed Products) and, in either case ((a) or (b)) if any such consent or agreement, as applicable, cannot be obtained with respect to a Licensed Product Agreement, at SFJ’s request in order to continue to Exploit Licensed Products following the date of delivery of the Program Transfer Notice to PB, PB shall, and shall cause its Affiliates, obtain for SFJ substantially all of the practical benefit and burden under such License Product Agreement to the extent applicable to the Licensed Products, including by entering into appropriate and reasonable alternative arrangements on terms agreeable to SFJ and subject to the consent and control of SFJ; provided that PB’s obligations shall continue only for so long as is reasonably necessary for SFJ to secure alternative arrangements directly with one or more Third Parties through the exercise of commercially reasonable efforts. 1.9 At SFJ’s written request, PB shall supply to SFJ the Licensed Compounds and Licensed Products then being manufactured by or on behalf of PB or its Affiliates, in such quantities as SFJ indicates in written forecasts and orders therefor from time to time; provided that (a) PB shall not be required to supply quantities that exceed PB’s reasonable forecasts, if any, prepared prior to termination and not in anticipation of termination, with respect to necessary clinical or commercial quantities, as applicable, for the relevant period, (b) each forecast submitted by SFJ to PB shall be made in compliance with the requirements of PB’s clinical or commercial (as applicable) supply agreement with its CMO and (c) SFJ shall provide each such forecast to PB prior to the date PB is required to deliver its corresponding forecast to the applicable CMO. PB shall supply such Licensed Compounds and Licensed Products at a supply price equal to [***] to Manufacture such Licensed Compounds and Licensed Products, as applicable. Unless SFJ no longer desires to obtain such Licensed Compounds and Licensed Products, PB shall supply such Licensed Compounds and Licensed Products manufactured in accordance with GMP and the then current CMC Information included in the IND or BLA (as applicable) submitted to the applicable Regulatory Authority in adequate quantities to meet SFJ’s forecasted requirements of Licensed Compound and Licensed Product made in accordance with the preceding provisions of this Section 1.9 until the earlier of (i) such time as SFJ has established an alternate, validated source of supply for the Licensed Compounds and Licensed Products and SFJ is receiving supply from such alternative source and (ii) (x) if such termination occurs prior to the First Commercial Sale of Licensed Product, the first (1st) anniversary of the date of delivery of the Program Transfer Notice to PB or (y) if such termination occurs after the First Commercial Sale of Licensed Product, the second (2nd) anniversary of the date of delivery of the Program Transfer Notice to PB. It is the intention of the Parties that following Program Transfer, SFJ shall have all rights necessary from PB to Develop and Commercialize the Product. Accordingly PB agrees on behalf of itself and its Affiliates to take such actions and to reasonably cooperate with SFJ as may be necessary to enable SFJ and its sublicensees to Develop and Commercialize the Product. 2. Effect of Termination of Co-Development Agreement. For clarity, and notwithstanding any other provision of the Co- Development Agreement or this Agreement to the contrary, SFJ’s right to exercise its right to obtain a Program Transfer pursuant to Section 3.20 of the Co-Development Agreement and SFJ’s right to exercise any right to terminate the Co-Development Agreement pursuant to Section 14.2 thereof shall not be mutually exclusive, provided that if SFJ exercises its right to obtain a Program Transfer pursuant to Section 3.20 of the Co-Development Agreement prior to termination of the Co-Development Agreement, all amounts PB is required to pay with respect to Development Costs (or a percentage or multiple thereof, as applicable) upon termination of the Co-Development Agreement pursuant to Section 14.2 of the Co-Development Agreement as set forth in the applicable subsection thereof, and does pay (“Termination Payments”), shall be factored in to the amounts SFJ is entitled to recover pursuant to Section 3.1 as set forth in Sections 3.2(a) and 3.2(b). 3. Payments. 3.1 In the event of a Program Transfer, all further payment obligations of SFJ under Article 4 of the Co-Development Agreement shall terminate and be of no further force or effect; provided, however, from and after such time following the Program Transfer (if ever) as SFJ’s and its Affiliates’ total Program Net Profits (defined below) from the Commercialization and (sub)licensing of Licensed Compounds and Licensed Products equal the 3x Return (defined below) and provided that PB has fulfilled all of its obligations pursuant to Section 1 hereof and subject to Section 13.2.1 of the Co-Development Agreement, SFJ shall pay to PB royalties equal to: (a) with respect to sales of Licensed Products in the US and the European Countries by SFJ, its Affiliates or by Third Party (sub)licensee(s) of SFJ or its Affiliates (and such (sub)licensee’s(s’) further sublicensees), [***] of aggregate Net Sales of Licensed Products in the US and the European Countries; and (b) with respect to sales of Licensed Products in the ROW by SFJ, its Affiliates or by Third Party (sub)licensee(s) of SFJ or its Affiliates (and such (sub)licensee’s(s’) further sublicensees), only from and after such time following the Program Transfer (if ever) as SFJ’s and its Affiliates’ total Program Net Profits (defined below) from the Commercialization and (sub)licensing of Licensed Compounds and Licensed Products equal the 5x Return (defined below), [***] of aggregate Net Sales of Licensed Products in the ROW. 3.2 For purposes of this Section 3: (a) “3x Return” means (i) 300% of SFJ Total Costs (defined below), less (ii) the sum of (x) the total amount of Approval Payments (if any) paid by PB before or after the Program Transfer and (y) the amount of any Termination Payments paid by PB upon or after any termination of the Co-Development Agreement. (b) “5x Return” means (i) 500% of SFJ Total Costs (defined below), less (ii) the sum of (x) the total amount of Approval Payments (if any) paid by PB before or after the Program Transfer and (y) the amount of any Termination Payments paid by PB upon or after any termination of this Agreement. (c) “European Countries” means [***]. (d) “Manufacture” has the meaning ascribed to such term in the AZ License. (e) “Net Sales” has the meaning ascribed to such term in the AZ License, mutatis mutandis. (f) “Program” means all activities by SFJ, PB, or Third Parties associated with the Development, Commercialization and Manufacture of the Licensed Product. (g) “Program Net Profits” means the cumulative amount of cash proceeds derived from the Program (net of a reasonable cash reserve for working capital and capital expenditures) which are distributed or distributable by SFJ to its constituent partners. SFJ agrees to promptly distribute such amount of cash proceeds (net of such reserves) to its constituent partners. (h) “Regulatory Exclusivity Period” has the meaning ascribed to such term in the AZ License, mutatis mutandis. (i) “ROW” means all countries of the world outside of the United States and the European Countries. (j) “Royalty Term” means, with respect to the Licensed Product in the United States and each of the European Countries, the period beginning on the date that SFJ first becomes obligated to pay royalties to PB pursuant to Section 3.1 and ending on the latest to occur of (i) the tenth (10th) anniversary of the First Commercial Sale of the Licensed Product in such country, (ii) the expiration of the last-to-expire Licensed Patent covering the manufacture, use or sale of the Licensed Product in such country, and (c) the expiration of Regulatory Exclusivity Period, if any, for the Licensed Product in such country. (k) “SFJ Total Costs” means all capital invested by SFJ in the Program. 3.3 Royalty Term. SFJ shall have no obligation to pay any royalty with respect to Net Sales in any country with respect to any period after the Royalty Term in such country has expired, and any Net Sales in any country with respect to any period after the Royalty Term in such country has expired shall be excluded for purposes of calculating royalties due under Section 3.1. 3.4 Reductions. In the event that SFJ assumes from PB pursuant to Section 1.1, or enters into any agreement with a Third Party (including MedImmune or its Affiliates) in order to obtain or maintain a license to a Patent of such Third Party (including a Licensed Patent) that is necessary for the Manufacture, use or sale of a Licensed Product in any country (a “Third Party Patent Right”), under which agreement SFJ is obligated to pay [***], SFJ shall be entitled to deduct from royalties payable hereunder in a given Calendar Quarter in such country [***] actually paid to such Third Party with respect to such Calendar Quarter under such agreement, solely to the extent that: (i) such [***] (a) are triggered by sales of the Licensed Products that would, absent such agreement, infringe such a Third Party Patent Right that is licensed in such country in such Calendar Quarter under such agreement, (b) are otherwise exclusively attributable to such Third Party Patent Right, and (c) exceed [***] of Net Sales of Licensed Products in such country in such Calendar Quarter; and (ii) SFJ does not deduct such [***] paid to such Third Party from the royalties payable by SFJ to another Third Party licensee of a different Third Party Patent Right. SFJ, upon request by PB, shall provide reasonable evidence, including a copy of any applicable agreement, of such [***] actually paid to such Third Party with respect to such Third Party Patent Right. Examples of the calculation of the foregoing deduction [***] are set forth in Exhibit A hereto. If the amount of such [***] which SFJ shall be entitled to deduct with respect to a country in a particular Calendar Quarter shall exceed the royalties payable to PB with respect to Net Sales of Licensed Products in such country in such Calendar Quarter, SFJ shall be entitled to deduct the balance of the total amount of such deduction from the royalties payable to PB with respect to Net Sales of Licensed Products in such country in subsequent Calendar Quarters, and in no event shall PB be obligated to pay any “negative royalty” to SFJ under this Agreement. Notwithstanding the foregoing, Third Party Patent Rights shall not include any Patent of a Third Party that is not necessary for the Manufacture, use or sale of Licensed Products (1) in the form(s) and formulation(s) being clinically developed or Commercialized by or on behalf of PB as of the date of delivery of the Program Transfer Notice, and (2) manufactured using the manufacturing processes and manufacturing technologies being used by or on behalf of PB in the manufacture of Licensed Products for clinical development or Commercialization as of the date of delivery of the Program Transfer Notice, and any [***] payable by SFJ to any Third Party with respect to Licensed Products for a license of a Patent to any formulation, delivery or manufacturing technology that is not being used by PB for Licensed Products as of the date of delivery of the Program Transfer Notice shall be the sole responsibility of SFJ. [***]. 3.5 On a quarterly basis following a Program Transfer until SFJ becomes obligated to, and does, deliver its first royalty report to PB as set forth in Section 3.6, SFJ shall provide written reports to PB within [***] after the end of each Calendar Quarter setting forth: (a) capital invested by SFJ in the Program during such Calendar Quarter; (b) SFJ Total Costs since the date of the Program Transfer; and (c) as applicable: (i) in the case of any country in which SFJ or any of its Affiliates is directly Commercializing Licensed Products, Net Sales of Licensed Products in all such countries in such Calendar Quarter, including, on a Licensed Product-by-Licensed Product and country-by-country basis, the number and type of each Licensed Product sold, gross sales, Net Sales, itemized deductions by major cost category as set forth in the definition of Net Sales, and the exchange rates used; and/or (ii) (A) in the case of any country in which a Third Party (sub)licensee of SFJ or its Affiliate is Commercializing Licensed Products, all royalties received by SFJ or its Affiliate with respect to sales of Licensed Products by such (sub)licensee and its further sublicensees in all such countries, and (B) all other (sub)license revenue received by SFJ or its Affiliate from such Third Party (sub)licensee and its further (sub)licensees in consideration of the grant of Commercialization rights with respect to Licensed Products, including upfront fees, license maintenance fees and milestone payments, in each case, in such Calendar Quarter; and Sections 3.5(a), 3.5(b) and 3.5(c) in a currency other than U.S. dollars into U.S. dollars. (d) the exchange rates used to convert any of the amounts paid, incurred, invoiced or received (as applicable) under 3.6 Royalties payable to PB under this Section 3 shall be calculated and reported for each Calendar Quarter and shall be paid (i) within [***] of the end of the Calendar Quarter with respect to Net Sales of Licensed Products by SFJ and its Affiliates, and (ii) within [***] after SFJ receives its royalty payment from a third-party licensee with respect to Net Sales of Licensed Products by such third-party licensee. Each payment of royalties paid to PB shall be accompanied or preceded by a report of royalties payable, in sufficient detail to permit confirmation of the accuracy of the payment made, including: (a) the information described in Sections 3.5(a) and 3.5(b); (b) on a Licensed Product-by-Licensed Product and country-by-country basis, the information described in Section 3.5(c)(i) and clause (A) of Section 3.5(c)(ii); (c) on a Third Party (sub)licensee-by-Third Party (sub)licensee basis, the information described in clause (B) of Section 3.5(c)(ii); and (d) the information described in Section 3.5(d). All royalty payments by SFJ to PB under this Section 3 shall be paid in U.S. dollars. If any currency conversion shall be required in connection with the calculation of royalty payments payable hereunder, such conversion shall be calculated at the rate of exchange for such currency used throughout SFJ’s accounting system in conformity with GAAP for the Calendar Quarter for which payment is due, or the actual rate of exchange used by a third-party licensee for payment of a royalty to SFJ, on a country- by-country basis. All royalty payments shall be made by wire transfer to a bank and account designated in writing by PB, unless otherwise specified in writing by PB. 3.7 SFJ shall, and shall cause its Affiliates and its and their (sub)licensees to, keep complete and accurate financial books and records pertaining to the Commercialization of Licensed Products hereunder, including books and records of the information described in Sections 3.5 and 3.6, in sufficient detail to calculate and verify all amounts payable hereunder. SFJ shall, and shall cause its Affiliates and its and their (sub)licensees to, retain such books and records for [***] after the end of the Calendar Year to which such books and records pertain. 3.8 At the request of PB, no more than once each Calendar Year, SFJ shall, and shall cause its Affiliates and its and their (sub)licensees to, permit an independent certified public accounting firm of international standing designated by PB and reasonably acceptable to SFJ (the “Auditor”), at reasonable times and upon at least [***] prior written notice, to audit the books and records maintained pursuant to Section 3.7 in the location where such books and records are maintained, solely to confirm payments due from SFJ under Section 3 for a period covering not more than the preceding three (3) Calendar Years. No Calendar Year shall be subject to audit under this Section 3.8 more than once, provided that if such records of SFJ, its Affiliates, and its and their (sub)licensees for a given Calendar Year have already been audited pursuant to the AZ License and SFJ has provided a true and complete copy of the report from such audit to PB, then PB shall only be entitled to audit SFJ’s books and records with regard to items not covered by such audit report, and provided further that [***]. If MedImmune conducts any audit of the books and records of SFJ, its Affiliates, and its and their (sub)licensees pursuant to the AZ Agreement, SFJ shall provide a true and complete copy of the report from such audit to PB within [***] after SFJ receives such report. PB and SFJ shall reasonably cooperate to minimize the burden to SFJ and the expense of conducting any such audit. The Auditor will execute a reasonable written confidentiality agreement with SFJ and will disclose to PB only such information as is reasonably necessary to provide PB with information regarding any actual or potential discrepancies between amounts reported and actually paid and amounts payable under this Agreement. The Auditor will send a copy of the report to SFJ at the same time it is sent to PB. The report sent to both Parties will include the methodology and calculations used to determine the results. PB shall bear the full cost of such audit, unless the audit reveals an underreporting or underpayment by SFJ by more than the greater of (i) [***] or (ii) [***] of the amount due for any Calendar Year, in which case SFJ shall bear the cost of the audit. If such audit concludes that (a) additional amounts were owed by SFJ, SFJ shall pay the additional amounts, with interest from the date originally due at the rate of [***], or (b) excess payments were made by SFJ, PB shall reimburse such excess payments, in either case ((a) or (b)), within [***] after the date on which the Auditor’s report is delivered to SFJ. 4. Miscellaneous. 4.1 Complete Agreement.
