Business Overview We are a clinical-stage therapeutics company focused on developing innovative products at the intersection of drugs and devices that address significantunmet medical needs in the treatment of cardiopulmonary diseases. Our focus is the continued development of our nitric oxide therapy for patients withpulmonary hypertension, or PH, using our proprietary delivery system, INOpulse, with pulmonary arterial hypertension, or PAH, representing the leadindication. Our INOpulse platform is based on our proprietary pulsatile nitric oxide delivery device.In February 2016, we announced positive data from the final analysis of our Phase 2 long-term extension clinical trial of INOpulse for PAH, whichwas Part 2 of our Phase 2 clinical trial of INOpulse for PAH. The data indicated a sustainability of benefit to PAH patients who received INOpulse therapy atthe 75 mcg/kg of ideal body weight/hour dose for an average of greater than 12 hours per day and were on long-term oxygen therapy, or LTOT. Afterreaching agreement with the U.S. Food and Drug Administration, or FDA, and the European Medicines Agency, or EMA, on our Phase 3 protocol, we aremoving forward with Phase 3 development. In September 2015, the FDA agreed to a Special Protocol Assessment, or SPA, for our Phase 3 PAH program forINOpulse, which will include two confirmatory clinical trials. The first of the two Phase 3 trials, or INOvation-1, has been initiated with the first patientenrolled in June 2016. During January 2017, we received confirmation from the FDA of its acceptance of all modifications proposed by us to our Phase 3program. Under the newly modified Phase 3 program, the ongoing one-year INOvation-1 study, and a second confirmatory randomized withdrawal study withapproximately 40 patients who will be crossing over from the INOvation-1 study, can serve as the two adequate and well-controlled studies to support a NewDrug Application,or NDA, submission for INOpulse in PAH subjects on LTOT. Both studies include an interim analysis approximately half-way through eachstudy to assess for efficacy and futility. The interim analysis for the INOvation-1 study also includes a potential sample size reassessment.We completed a randomized, placebo-controlled, double-blind, dose-confirmation Phase 2 clinical trial of INOpulse for PH-COPD in July 2014. Wereceived results from this trial, and we have initiated further Phase 2 testing. In September 2015, an oral presentation of late-breaking data from a clinical trialsponsored by us was presented at the European Respiratory Society International Congress 2015 in Amsterdam. The data showed that INOpulse improvedvasodilation in patients with PH-COPD. In July 2016, the results were published in the International Journal of COPD in an article titled "Pulmonary vasculareffects of pulsed inhaled nitric oxide in COPD patients with pulmonary hypertension". Building upon this and other work we have done during recentquarters, we have initiated Phase 2 testing for the use of the INOpulse device for PH-COPD patients to evaluate the potential benefit of chronic use onexercise capacity, and enrolled the first patient in October 2016.We have begun clinical testing of the INOpulse therapy to treat PH associated with idiopathic pulmonary fibrosis, or PH-IPF, based on feedback fromthe medical community and the large unmet medical need for this condition. Our first patient was enrolled in our Phase 2 study in the second quarter of 2016.In addition, other opportunities for the application of our INOpulse platform include the following indications: chronic thromboembolic PH, or CTEPH, PHassociated with sarcoidosis and PH associated with pulmonary edema from high altitude sickness.We have devoted all of our resources to our therapeutic discovery and development efforts, including conducting clinical trials for our productcandidates, protecting our intellectual property and the general and administrative support of these operations. We have devoted significant time andresources to developing and optimizing INOpulse which operates through the administration of nitric oxide as brief, controlled pulses that are timed to occurat the beginning of a breath.To date, we have generated no revenue from product sales. We expect that it will be several years before we commercialize a product candidate, ifever. Our Development Program The following table summarizes key information about INOpulse and indications for which we have worldwide commercialization rights.4 From the inception of our business through December 31, 2016, $243.9 million was invested in our development programs. Prior to our February 2015initial public offering, or IPO, our sole source of funding was investments in us by our former parent company, Ikaria, Inc. (a subsidiary of Mallinckrodt plc),or Ikaria. As used herein, unless the context otherwise requires, references to “Ikaria” refer to Ikaria, Inc. and its subsidiaries and any successor entity.INOpulseOur INOpulse program is an extension of the technology used in hospitals to deliver continuous-flow inhaled nitric oxide. Use of inhaled nitricoxide is approved by the FDA and certain other regulatory authorities to treat persistent PH of the newborn. Ikaria has marketed continuous-flow inhalednitric oxide as INOmax for hospital use in this indication since FDA approval in 1999. In October 2013, Ikaria transferred to us exclusive worldwide, royalty-free rights to develop and commercialize pulsed nitric oxide in PAH, PH associated with chronic obstructive pulmonary disease, or PH-COPD, and PHassociated with idiopathic pulmonary fibrosis, or PH-IPF. In July 2015, we expanded the scope of our license to allow us to develop our INOpulse program forthe treatment of chronic thromboembolic PH, or CTEPH, PH associated with sarcoidosis and PH associated with pulmonary edema from high altitude sicknesswith a royalty equal to 5% of net sales of any commercial products for these three additional indications. In November 2015, we entered into an amendmentto our exclusive cross-license, technology transfer and regulatory matters agreement with Ikaria that included a royalty equal to 3% of net sales of anycommercial products for PAH. Our INOpulse program is built on scientific and technical expertise developed for the therapeutic delivery of inhaled nitricoxide. In 2010 and 2012, respectively, Ikaria submitted investigational new drug applications, or INDs, for INOpulse for the treatment of patients with PAHand PH-COPD. PAH is a form of PH that is closely related to persistent PH of the newborn. These INDs were included in the assets that were transferred to usby Ikaria.Nitric oxide is naturally produced and released by the lining of the blood vessels and results in vascular smooth muscle relaxation, an importantfactor in regulating blood pressure. Relaxation of the muscles of the blood vessels allows the heart to increase blood flow to tissues and organs of the body,including the lung. When administered through inhalation, nitric oxide acts to selectively reduce pulmonary arterial pressure in the lung with minimal effectson blood pressure outside of the lungs, an important safety consideration.Inhaled nitric oxide is widely used in the hospital setting for the treatment of a variety of conditions and, as reported by Ikaria, over 600,000 patientshave been treated with inhaled nitric oxide worldwide since its first such use. However, chronic outpatient use of this therapy has previously been limited bya lack of a safe and compact delivery system for outpatient use. We have designed our INOpulse device, which is the means by which inhaled nitric oxide isdelivered to the patient, to be portable, which enables use by ambulatory patients on a daily basis inside or outside their homes. Our INOpulse device has aproprietary mechanism that delivers brief, targeted pulses of nitric oxide timed to occur at the beginning of a breath for delivery to the well-ventilated alveoliof the lungs, which minimizes the amount of drug required for treatment. We estimate this, and the higher concentration of nitric oxide we use, reduces thevolume of drug delivered to approximately 5% of the volume required for equivalent alveolar absorption using standard continuous flow delivery systems,and also reduces the amount of nitric oxide, as well as its by-product nitrogen dioxide, that is exhaled and released into the patient’s environment. INOpulseis designed to automatically adjust nitric oxide delivery based on a patient’s breathing pattern to deliver a constant and appropriate dose of the inhaled nitricoxide over time, independent of the patient’s activity level, thus ensuring more consistent dosing of the nitric oxide to the alveoli of the lungs.In our previous Phase 2 INOpulse clinical trials, we used the first generation INOpulse device, which we refer to as the INOpulse DS device.Beginning with our Phase 3 trial of INOpulse for PAH in 2016, we have begun using our second generation device, which we refer to as the INOpulse device.The INOpulse device has approximately the same dimensions as a paperback book and weighs approximately 2.5 pounds. The INOpulse device has a simpleand intuitive user interface and a battery life of approximately 16 hours when recharged, which takes approximately four hours and can be done while thepatient sleeps. Based on the doses we have evaluated in our clinical trials, we expect that most patients will use two cartridges a day. The INOpulse deviceincorporates our proprietary triple-lumen nasal cannula, safety systems and proprietary software algorithms. The triple-lumen nasal cannula enables moreaccurate dosing of nitric oxide and minimizes infiltration of oxygen, which can react with nitric oxide to form nitrogen dioxide. Our triple-lumen nasalcannula consists of a thin, plastic tube that is5divided into three channels from end-to-end, including at the prongs that are placed in the patient’s nostrils, with one channel delivering inhaled nitric oxide,a second for breath detection and a third available for oxygen delivery. INOpulse is configured to be highly portable and compatible with long-term oxygentherapy, or LTOT, systems via nasal cannula delivery.The INOpulse device has been well received by patients in the usability research we have conducted. In addition to the baseline testing on theoriginal INOpulse DS device, we have conducted two rounds of testing with COPD and PAH patients to evaluate the user interface, loading mechanism, size,carrying bag and other features. In the usability research we have conducted, all eight patients with experience with the INOpulse DS device respondedpositively to the INOpulse device, and several of these patients indicated that the ability to take the INOpulse device outside the home would likely reduceconcerns with maintaining compliance. We conducted two studies to assess the environmental and the expiratory concentration of nitrogen dioxideassociated with use of the INOpulse delivery system. Both studies found that the nitrogen dioxide levels were below the National Ambient Air QualityStandards.Our technology is based on patents we have exclusively licensed from Ikaria for the treatment of PAH, PH-COPD, PH-IPF, CTEPH, PH associatedwith sarcoidosis and PH associated with pulmonary edema from altitude sickness which, collectively, we refer to as the Bellerophon indications. Theseinclude patents with respect to the pulsed delivery of nitric oxide to ensure a consistent dose over time, which expire as late as 2027 in the United States andas late as 2026 in certain other countries, as well as with respect to the special triple-lumen cannula that allows for safer and more accurate dosing of pulsednitric oxide, which expires in 2033 in the United States and abroad. We have also licensed several other patent applications from Ikaria for certain of theinnovations included in the INOpulse device and certain of the resulting patents, if issued, would expire as late as 2030 in the United States.During January 2016, the European Patent Office issued a Notice of Intention to Grant a European Patent that provides protection for our INOpulseprogram. The patent, entitled “System of Administering a Pharmaceutical Gas to a Patient,” covers the ability to provide a known amount of pharmaceuticalgas to a patient regardless of the patient inspiration rate or volume and distinguishes the INOpulse® delivery system from others on the market. This patentwas granted by the European Patent Office on March 30, 2016, and was subsequently validated in 30 European countries. Also during January 2016, wereceived European Conformity, or EC, Certification for our proprietary new, INOpulse® drug-device delivery system. This EC Certification grants CEmarking on the INOpulse product, which confirms INOpulse compliance with the essential requirements of the relevant European health, safety andenvironment protection legislation of the European Union. This certification covers the design, development and manufacture of inhaled pulsatile nitricoxide drug delivery systems including our triple-lumen cannula and application software.INOpulse for PAH We are developing INOpulse for the treatment of PAH to address a significant and unmet medical need in an orphan disease, which is a disease thataffects fewer than 200,000 individuals in the United States. This program represents a potential first-in-class therapy for this indication. In 2011, the FDAgranted orphan drug designation to our nitric oxide program for the treatment of PAH. If a product with an orphan drug designation is the first to receive FDAapproval, the FDA will not approve another product for the same indication that uses the same active ingredient for seven years, except in a limited number ofspecific situations such as another product being shown to be clinically superior.PAH is characterized by abnormal constriction of the arteries in the lung that increases the blood pressure in the lungs which, in turn, results inabnormal strain on the heart’s right ventricle, eventually leading to heart failure. While prevalence data varies widely, we estimate that there are a total of atleast 35,000 patients currently diagnosed with and being treated for PAH in the United States and European Union. Moreover, because PAH is rare and causesvaried symptoms, we believe there is significant under-diagnosis of the condition at its early stages. There are several approved therapies for PAH, and weestimate, based on public product sales data, that 2014 combined global sales for these therapies were over $4.6 billion with a compounded annual growthrate of approximately 7%. Most PAH patients are treated with multiple medications and many are on supportive therapy. We believe that 40 to 60% of PAHpatients are on LTOT. Despite the availability of multiple therapies for this condition, PAH continues to be a life-threatening, progressive disorder. A Frenchregistry initiated in 2002 and a U.S. registry initiated in 2006 estimate that the median survival of patients with PAH is three and five years from initialdiagnosis, respectively.We completed a randomized, placebo-controlled, double-blind Phase 2 clinical trial of INOpulse for PAH in October 2014, which was Part 1 of thetrial. In February 2016, we announced positive data from the final analysis of Part 2 of our Phase 2 clinical trial of INOpulse for PAH. The data reinforced theresults from October 2014 and indicated a sustainability of benefit to PAH patients who received INOpulse therapy at the 75 mcg dose for an average ofgreater than 12 hours per day and were also treated with LTOT. After reaching agreement with the FDA, and the EMA on our Phase 3 protocol, we are movingforward with Phase 3 development. In September 2015, the FDA agreed to a SPA for our Phase 3 PAH program for INOpulse, which will include twoconfirmatory clinical trials. The INOvation-1 trial has been initiated with the first patient enrolled in June 2016. During January 2017, we receivedconfirmation from the FDA of its acceptance of all modifications proposed by us to6our Phase 3 program. Under the newly modified Phase 3 program, the ongoing one-year INOvation-1 study, and a second confirmatory randomizedwithdrawal study with approximately 40 patients who will be crossing over from the INOvation-1 study, can serve as the two adequate and well-controlledstudies to support a NDA filing for INOpulse in PAH subjects on LTOT. Both studies include an interim analysis approximately half-way through each studyto assess for efficacy and futility. The interim analysis for the INOvation-1 study also includes a potential sample size reassessment. INOpulse for PH-COPD We are also developing INOpulse for the treatment of PH-COPD. COPD is a disease characterized by progressive and persistent airflow limitations.Patients with more severe COPD frequently have hypoxemia, or an abnormally low level of oxygen in the blood, and may be treated with LTOT. Despitetreatment with oxygen, hypoxemia can progress and contribute to PH. In 2010, Datamonitor estimated that over 1.4 million COPD patients in the UnitedStates were being treated with LTOT. Based on academic studies, we estimate that 50% of COPD patients on LTOT have PH. PH-COPD patients have a lowermedian life expectancy and a higher rate of hospitalization than COPD patients with similar respiratory disease but without PH. Currently, there are noapproved therapies for treating PH-COPD, and the only generally accepted treatments are LTOT, pulmonary rehabilitation and lung transplant. The overallCOPD market in the United States was estimated to be approximately $32 billion in 2010 with a compounded annual growth rate of approximately 4% (Fordet al., Chest, 2015, Vol 147, pp 31-45).The data from an initial three-month, open-label chronic-use Phase 2 trial conducted by a third party, which we in-licensed, showed that pulsedinhaled nitric oxide significantly reduced pulmonary arterial pressures in PH-COPD patients on LTOT and did so without causing hypoxemia, which is asignificant concern for these patients. The FDA asked us to confirm the dose range and the safety related to hypoxemia in PH-COPD patients using theINOpulse device, prior to proceeding to large scale trials. Following this guidance, we conducted a Phase 2 acute dose ranging randomized placebo-controlled trial in 159 patients with the INOpulse DS device, with doses ranging from 3 mcg to 75 mcg. This trial, which we completed in July 2014,identified a dose range that showed similar reduction in pulmonary arterial pressure versus baseline when compared to the initial acute effects of pulsedinhaled nitric oxide in the original chronic-use trial. In addition, in our confirmatory trial, none of the INOpulse doses tested had an adverse effect onhypoxemia relative to placebo. While the reduction in pulmonary arterial pressure did not reach statistical significance versus placebo in this acute setting,which was the primary endpoint of the trial, we believe that the results have confirmed a dose range for this therapy that delivers a significant reduction inpulmonary arterial pressure versus baseline and does not cause hypoxemia in patients with PH-COPD. In September 2015, an oral presentation of late-breaking data from a clinical trial sponsored by us was presented at the European Respiratory Society International Congress 2015 in Amsterdam. The datashowed that INOpulse improved vasodilation in patients with PH-COPD. In July 2016, the results were published in the International Journal of COPD in anarticle titled "Pulmonary vascular effects of pulsed inhaled nitric oxide in COPD patients with pulmonary hypertension". Building upon this and other workwe have done during recent quarters, we have initiated additional Phase 2 testing for the use of the INOpulse device for PH-COPD patients to evaluate thepotential benefit of chronic use on exercise capacity, and enrolled the first patient in October 2016.INOpulse for PH-IPFWe are also developing INOpulse for the treatment of PH-IPF. IPF is a progressive disease of unknown etiology associated with growth of fibrotictissue in the lungs causing hypoxemia, dyspnea, fatigue and cough. The median survival is only two to three years. Based on academic studies, we estimatethe prevalence of IPF in the United States at approximately 90,000 patients (Raghu et al., Am J RespirCare Med, 2006, Vol 174, pp810-816), with 20-40%suffering from pulmonary hypertension (Rivera-Lebron, MD, MSCE, Advances in Pulmonary Hypertension, 2013, Vol 12, pp127-134). PH with IPF increasesmortality. The presence of PH correlates most closely with the need for oxygen therapy. The two therapies that are currently approved for IPF, nintedanib andperfinidone cost approximately $100,000 per year (Pulmonary Fibrosis News, Oct 23, 2014).iNO may improve outcomes in PH-IPF by both improving Ventilation-Perfusion, or V/Q, matching with increases in arterial oxygenation and bylowering pulmonary artery pressures. It has been shown (Yoshida et al., Eur Respir J 1997: 10: 2051-2054) that inhalation of nitric oxide significantlyreduced the mean pulmonary arterial pressure and the pulmonary vascular resistance as compared with room air alone. However, the arterial oxygen tension(PaO2) did not improve. The combined inhalation of nitric oxide and oxygen produced a significant decrease of pulmonary arterial pressure (p<0.01) as wellas an improvement (p<0.05) in PaO2 as compared to oxygen alone. These findings support the potential for the combined use of nitric oxide and oxygen fortreating idiopathic pulmonary fibrosis patients with pulmonary hypertension. We also initiated our Phase 2 study in PH-IPF consisting of an exploratoryacute hemodynamic study, for which the first patient was enrolled in second quarter of 2016, to be followed by an exercise capacity study.BCM7In December 2011, we initiated a clinical trial of BCM, which we refer to as our PRESERVATION I trial, and completed enrollment in December 2014.Top-line results from the randomized, double-blind, placebo-controlled clinical trial were announced in July 2015. Topline results showed no statisticallysignificant treatment differences between patients treated with BCM and patients treated with placebo for both the primary and the secondary endpoints.Following the results, we are considering further exploratory work but we do not intend to proceed with further clinical development of BCM at this pointuntil and unless we can determine an alternative path forward. We continue to maintain the patent portfolio, including the composition of matter and methodmanufacturing patents that we have in-licensed from BioLineRx Ltd. In addition, we continue with trial management and close out activities for thePRESERVATION I trial in accordance with GCP requirements.Our Strategy Our goal is to become a leader in developing and commercializing innovative products at the intersection of drugs and devices that addresssignificant unmet medical needs in the treatment of cardiopulmonary diseases. The key elements of our strategy to achieve this goal include: •Advance the clinical development of INOpulse. One of our lead indications for our product candidate is INOpulse for PAH. Our Phase 3 PAHprogram for INOpulse will include two confirmatory clinical trials including the ongoing INOvation-1 trial and a second confirmatory randomizedwithdrawal study. The INOvation-1 trial has been initiated with the first patient enrolled in June 2016. We also initiated our second Phase 2 studyfor INOpulse in PH-COPD looking at the effect of chronic use on exercise capacity, for which the first patient was enrolled in October 2016. Wealso initiated our Phase 2 studies in PH-IPF consisting of an exploratory acute hemodynamic study, for which the first patient was enrolled insecond quarter of 2016, to be followed by an exercise capacity study. •Leverage our historical core competencies to expand our pipeline. Our employees have years of institutional experience in the use of inhaled nitricoxide in treating PH and in the development of drug-device combination product candidates. If we successfully advance INOpulse, we expect todevelop INOpulse for treatment of CTEPH, PH associated with sarcoidosis and PH associated with pulmonary edema from altitude sickness and,subject to obtaining additional license rights from Ikaria, potentially other outpatient PH indications. Our longer-term vision is to identify andopportunistically in-license innovative therapies that are at the intersection of drugs and devices and to develop and commercialize these productcandidates.•Build commercial infrastructure in select markets. As we near completion of the development of our product candidates, we may build acommercial infrastructure to enable us to market and sell certain of our product candidates with a specialized sales force and to retain co-promotionor similar rights, when feasible, in indications requiring a larger commercial infrastructure. While we may partner with third parties tocommercialize our product candidates in certain countries, we may also choose to establish commercialization capabilities in select countriesoutside the United States. INOpulse INOpulse Scientific Background Nitric oxide is a naturally occurring molecule produced by many cells of the body. Researchers found that nitric oxide is produced and released bythe lining of the blood vessels and plays a role in controlling muscle tone in blood vessels. In particular, nitric oxide results in vascular smooth musclerelaxation in blood vessels and thus is an important factor in regulating blood pressure. As the muscles of the blood vessels relax, blood flow increases,helping the heart to deliver more blood to the body. PH patients can have a deficiency in endogenous nitric oxide production in their lungs. Whenadministered by inhalation to patients with PH, we expect inhaled nitric oxide to act in a similar manner to naturally produced nitric oxide.The scientific journal Science named nitric oxide Molecule of the Year in 1992. Additionally, the three researchers who discovered the role of nitricoxide as a signaling molecule in the cardiovascular system earned the Nobel Prize for Physiology or Medicine in 1998.In 1991, Dr. Warren Zapol and his associates at the Massachusetts General Hospital discovered that inhaling nitric oxide in gas form could reducehigh blood pressure in the lungs, a condition known as PH. Nitric oxide is a rapid and potent vasodilator, which means it dilates, or widens, blood vessels.When inhaled, it quickly dilates blood vessels in the lungs, which reduces blood pressure in the lungs, strain on the right ventricle and shunting of de-oxygenated blood away from the lungs. Because more blood can flow through the lungs, oxygen levels within blood improve. In addition, inhaled nitricoxide improves8the efficiency of oxygen delivery, and because it is a gas, it goes only to the portions of the lung that are ventilated, or receiving air flow, and increases bloodflow only in these areas. Thus, inhaled nitric oxide improves ventilation-perfusion matching, an important element of lung function involving the air thatreaches the lungs, or ventilation, and the blood that reaches the lungs, or perfusion. Inhaled nitric oxide is quickly inactivated after contact with blood, and isselective for the lungs, meaning that it has minimal effects on blood pressure outside of the lungs, which is an important safety consideration.In 1999, the FDA approved the use of inhaled nitric oxide for the short-term treatment of persistent PH of the newborn. Based on this approval, andsimilar approvals from foreign regulatory authorities, continuous-flow inhaled nitric oxide, which is administered to ventilated patients by a dedicated in-hospital device, is marketed by Ikaria and its commercialization partners worldwide as INOmax (INOflo in Japan). Inhaled nitric oxide is widely used in thehospital setting for a variety of conditions and, as reported by Ikaria, over 600,000 patients have been treated with inhaled nitric oxide worldwide since itscommercial launch. However, chronic outpatient use of this therapy has previously been limited by the lack of a safe and compact delivery system foroutpatient use.Introduction to Pulmonary Hypertension PH is a disease characterized by constriction of the blood vessels in the lung, which causes blood pressure in the lung to rise and, in turn, increasesthe work required for the right ventricle of the heart to pump blood. The World Health Organization, or WHO, has endorsed a consensus classification for PHthat was updated most recently in 2013. The WHO classification has five broad PH groups based on similarities in pathological and hemodynamiccharacteristics and therapeutic approaches. We are initially focusing development of INOpulse in indications included in WHO Groups 1 and 3 due to ourview of the likelihood of success and the size and commercial viability of these markets. Group 1 PH is comprised of patients with PAH. This Group combinesconditions with a range of causes, all of which have a characteristic pattern of vascular remodeling. The constriction of the blood vessels and the resultingpressure on the heart is often the major reason for poor prognosis of PAH patients since they can be otherwise healthy. Most PAH-specific medications arevasodilators and work through one of the three key mechanistic pathways for vasoconstriction and vasodilation. We expect that, because inhaled nitric oxideis a vasodilator and PH patients can have a deficiency in endogenous nitric oxide production in their lungs, patients in Group 1 will benefit from INOpulse.Group 3 PH consists of PH associated with lung disease or hypoxemia, which is an abnormally low level of oxygen in the blood. This Group includes patientswith PH-COPD and PH-IPF, among others. INOpulse for Pulmonary Arterial Hypertension We are developing INOpulse for PAH to address a significant and unmet medical need in an orphan disease. This product candidate represents thedevelopment of a potential first-in-class therapy for this indication. Although current therapy for PAH provides some therapeutic benefit, there remains nocure, and approved therapies can have significant systemic side effects, such as hypotension and liver injury. INOpulse for PAH is designed to be a selective,short-acting pulmonary vasodilator and is being tested as an add-on therapy to existing PAH medications to evaluate its efficacy and side effect profile, inparticular its ability to provide clinical benefit without adding to the systemic effects of other therapies such as hypotension.Disease Background and Market OpportunityPAH is a life-threatening, progressive disorder characterized by abnormally high blood pressure, or hypertension, in the pulmonary artery, the bloodvessel that carries blood from the heart to the lungs. PAH occurs when most of the very small arteries, or arterioles, throughout the lungs narrow in diameter,which increases the resistance to blood flow through the lungs. To overcome the increased resistance, pressure increases in the pulmonary artery and the rightventricle, which is the heart chamber that pumps blood into the pulmonary artery. In addition, PAH may cause changes to the blood vessel lining that hinderthe natural production of nitric oxide. Signs and symptoms of PAH occur when this increased pressure in the right ventricle cannot fully overcome theelevated resistance.There are a number of drugs approved for the treatment of PAH that work primarily by reducing pulmonary vascular resistance, which is the primaryproblem for these patients. The currently approved PAH medications slow down disease progression, but do not prevent the underlying disease. Despite theavailability of multiple therapies for this condition, the mortality rate for PAH remains high, with estimates of median survival ranging from three to fiveyears. Currently, the only definitive treatment for PAH is a lung transplant, which is only available to a minority of patients due to the strict requirements andavailability of viable lungs for transplant. Patients with PAH also report severe impairment of health-related quality of life, including poor general andemotional health and impaired physical functioning. The most common symptoms of PAH are shortness of breath during exertion and syncope, or faintingspells. People with PAH may experience additional symptoms, particularly as the condition worsens, including dizziness, swelling of the ankles or legs, chestpain and a racing pulse. These9impairments to health-related quality of life are comparable and sometimes more severe than those reported in patients with severely debilitating conditionssuch as spinal cord injury.Since PAH is an orphan condition with poor diagnosis rates, published prevalence estimates for PAH vary widely. Based on epidemiological studiesand current treatment rates, we estimate that there are a total of at least 35,000 patients currently diagnosed and treated for PAH in the United States andEuropean Union. The average age of PAH patients at diagnosis is approximately 50 years, and approximately 80% of PAH patients are female. PAH is oftendiagnosed late in the disease progression with approximately 73% of these patients already having progressed to WHO functional Class III or IV at the timeof diagnosis.PAH is characterized by abnormal constriction of the arteries in the lung. PAH patients are generally treated with one or more of the four majorclasses of approved medications, which are prostacyclin and prostacyclin analogs, phosphodiesterase type-5 inhibitors, endothelin receptor antagonists and asoluble guanylate cyclase stimulator, all of which potentially result in vasodilatory systemic effects and, therefore, hypotension. Current guidelinesrecommend treatment with multiple medications in Class III and IV patients with progressive disease but suggest treatment be carefully managed byexperienced physicians. Approximately 45% of PAH patients are treated with more than one class of medication at a given time. In addition, sincehypoxemia can be a problem in these patients, it is often treated with LTOT in accordance with broadly supported treatment guidelines in the United Statesand European Union.We are testing INOpulse for PAH as an add-on therapy for use in patients whose disease is progressing and who use additional medications. If it isapproved, we expect INOpulse will provide the greatest benefit to patients who require pulmonary arterial pressure reductions beyond the reductionsachieved with the medication they are already using. Because of its localized effect and short-half life, we do not expect INOpulse will add to systemic bloodpressure reductions of other PAH drugs. We believe that INOpulse is also likely to be preferentially prescribed for patients already on LTOT. Data from theREVEAL registry, a registry study of PAH based in the United States, indicate that approximately 40% of patients are treated with oxygen for hypoxemia. Amore recent assessment of the use of oxygen in the REVEAL registry found that 57% of PAH patients were on LTOT. Approximately 60% of the patients fromPart 1 of our Phase 2 clinical trial completed in October 2014 were on LTOT. We believe that, as compared to patients who are not using a nasal cannula,patients who are accustomed to using a nasal cannula for delivery of oxygen are more likely to be prescribed and are more likely to be compliant with the useof INOpulse.A 2013 report by CVS Caremark Specialty Analytics provided examples of PAH medications with annual prices ranging from approximately$100,000 to $150,000 per patient per year in the United States. We expect that, if approved, the price of INOpulse will be in the range of other establishedPAH medications. Scientific Rationale for Use of INOpulse for PAH Since the discovery of the significant role of nitric oxide in vasodilation, there has been an expectation in the scientific community that inhalednitric oxide could be an effective therapy for PAH. According to the Cleveland Clinic Center for Continuing Education section on Pulmonary Hypertension,exogenous administration of nitric oxide by inhalation is probably the most effective and specific therapy for PAH, but cost and technical complexity ofdelivering inhaled nitric oxide have limited its use to the hospital. Although not approved for the treatment of PAH, data from an in-hospital surveyconducted by Ikaria showed an estimated 1,000 to 2,000 INOmax uses in PAH patients in the United States each year, indicating that physicians already usenitric oxide in some PAH patients. The difficulty in delivering inhaled nitric oxide outside of the hospital results from the size of the device and cylinder andthe need for a specialized delivery system with built-in safety systems.We are developing nitric oxide for treatment of PAH because nitric oxide is a proven vasodilator, and PAH is primarily a disease of high pulmonaryvascular resistance. PAH is associated with impaired release of nitric oxide and thus we believe chronic administration of inhaled nitric oxide may be viewedas an adjunctive or replacement therapy in patients with PAH. The use of inhaled nitric oxide in PAH has been proposed since the role of nitric oxide in thisdisease was identified. This drug has been tested in limited investigational studies conducted at academic institutions.One clinical trial conducted by a third party at an academic center in Spain in 11 patients, seven of whom had severe PAH and four of whom hadsevere chronic thromboembolic PH, or CTEPH, evaluated the use of pulsed inhaled nitric oxide in an ambulatory setting. In this open-label, single-arm trialwith no placebo control, patients were given ambulatory pulsed inhaled nitric oxide therapy via a nasal cannula for up to one year, after being withdrawnfrom PAH-specific therapy. The nitric oxide pulse was delivered to the patient at the beginning of each inspiration at a flow rate that was individualized forsuch patient. The goal of this trial was to evaluate the efficacy and safety of long-term treatment with inhaled nitric oxide outside the hospital setting.At the start of this trial, patients were evaluated for various measures including the distance they were able to walk in six minutes and their WHOfunctional class status. At baseline, most of these patients had significant impairment of six-minute10walk distance, or 6MWD, with the ability to walk an average of 125 meters, and poor WHO functional class status, with nine patients in Class IV and twopatients in Class III. After one month of therapy, overall, patients improved based on WHO functional class, with six patients in Class III and five in Class II,and had improvements in 6MWD of 128 meters on average. After six months of treatment, patients did not worsen clinically, however, between months sixand 12, seven patients were given a phosphodiesterase type-5 inhibitor due to clinical worsening. One patient who initially did well with the addedphosphodiesterase type-5 inhibitor therapy developed severe right heart failure at month eight and died, and another patient received a lung transplant atmonth nine. The remaining nine patients all had clinical status at month 12 similar to their one month evaluation, and improvements in functional class and6MWD for the group persisted over time.We do not expect INOpulse to have systemic effects beyond the pulmonary vasculature because of the short half-life of nitric oxide combined withits targeted delivery to the alveoli. When nitric oxide is delivered as a pulse at the beginning of inhalation, it travels to the alveoli where it diffuses rapidlyacross the alveolar capillary membrane into the adjacent vascular smooth muscle of pulmonary vessels. This transport is similar to the natural transport ofendogenous nitric oxide from the endothelial cells, where it is produced, to the vascular smooth muscle cells where it relaxes the muscle and causesvasodilation of the pulmonary arteries. We believe this makes INOpulse unlikely to have intolerable side effects, such as systemic hypotension or drug-druginteractions. Given the need for PAH patients to be treated with multiple therapies and the potential for increased hypotension from each of the currentlyapproved PAH therapies, we are developing INOpulse as an add-on or adjunctive therapy for PAH, where we believe it has the highest commercial potential.Clinical Development Program INOpulse for PAH is designated as a drug-device combination by the FDA and is subject to review by the Division of Cardiovascular and RenalProducts within the Center for Drug Evaluation and Research with consultation from the Center for Devices and Radiological Health. Based upon our IND forPAH, the FDA has agreed that no further preclinical studies are required for clinical development of INOpulse for PAH.Phase 2 Clinical Trial In October 2014, we completed Part 1 of our ongoing Phase 2 clinical trial of INOpulse for PAH in the United States and Canada. Our key inclusioncriteria for patients in this trial were that they be diagnosed with PH WHO Group 1, be on at least one other PAH medication for at least 12 weeks prior totreatment with INOpulse; and demonstrate being able to walk between 100 and 450 meters within six minutes. In addition, this trial excluded patients withevidence of significant left ventricular dysfunction.The trial was a randomized, placebo-controlled, double-blind clinical trial with patients randomized 1:1:1 to placebo or to one of two active doses,either 25 or 75 mcg/kg ideal body weight/hour, (iNO 25 or iNO 75), for 16 weeks. The primary endpoint in this trial was a change in pulmonary vascularresistance from baseline to 16 weeks, which was the end of Part 1. The target change in pulmonary vascular resistance was 190 dynes sec. cm-5, and the trialwas powered for statistical significance at 130 dynes sec. cm-5. The main secondary endpoint was change in 6MWD over the same period. A clinicallymeaningful change in 6MWD is typically considered to be an increase of at least 30 to 35 meters.We randomized 80 patients for Part 1 of the Phase 2 clinical trial. The majority of the patients were female (79%), white (89%) and had idiopathicPAH (74%). The results from Part 1 of this trial, showed a trend toward lower pulmonary vascular resistance in both the active arms compared to placebo and atrend toward increased 6MWD in the higher dose group. However, neither result was statistically significant.However, among LTOT users, there was a clinically meaningful and statistically significant improvement versus placebo in both pulmonary vascularresistance and 6MWD in patients on the iNO75 dose.The Part 1 data analysis showed the following:•Patients on LTOT in the iNO 75 dose treatment arm who remained on INOpulse therapy for at least 12 hours a day had a mean improvement of 52.4meters as compared to baseline (n=13).•Patients on LTOT in the iNO 75 dose treatment arm who remained on INOpulse therapy for less than 12 hours a day showed a mean decrease of 10.7meters as compared to baseline (n=5).•Patients on LTOT in the iNO 25 dose treatment arm had a mean increase of 9.1 meters from baseline (n=15).•Patients on LTOT in the Placebo arm had a mean decrease of 10.7 meters from baseline (n=10).11The patients on LTOT in the iNO 75 dose treatment arm who remained on the INOpulse therapy for at least 12 hours a day had a placebo correctedincrease of 69.6 meters (increase of 52.4 meters for iNO 75 against a decrease of 17.2 meters for the corresponding placebo arm).INOpulse was relatively well-tolerated in Part 1 of this trial. Our Independent Data Safety Monitoring Board evaluated the safety analysis from Part 1of the trial in November 2014 and recommended proceeding with Part 2 of the trial. Possibly drug-related serious adverse events, or SAEs, occurred in nopatients in the placebo group and one subject in each of the iNO25 and iNO75 groups.One patient in the placebo arm died during Part 1 of the trial due to worsening PAH. SAEs were reported for four patients in the placebo arm,including one each of: pneumonia/worsening PAH, catheter-related infection, ascites and left hip sciatica. Each of these was assessed by the investigator forthe trial as unrelated. Four patients in the iNO25 low-dose active treatment arm experienced SAEs, including bacteremia, myelodysplastic syndrome,increased shortness of breath and dyspnea, one of which was assessed as possibly related to trial therapy. The iNO75 high-dose active treatment arm had ninepatients with SAEs. The most common SAEs reported in the iNO75 group were syncope and bronchitis/tracheobronchitis, one of which was assessed aspossibly related to trial therapy. Discontinuation of trial therapy due to adverse events, or AEs, occurred for two patients in the iNO75 arm and one subject ineach of the iNO25 and placebo arms.In February 2016, we announced positive data from the final analysis of our Phase 2 long-term extension clinical trial of INOpulse for PAH, whichwas Part 2 of our Phase 2 clinical trial of INOpulse for PAH. The data reinforced the results from October 2014 and indicated a sustainability of benefit to PAHpatients who received iNO75 dose therapy for an average of greater than 12 hours per day and were also treated with LTOT.Following 16 weeks of blinded therapy in Part 1 of the trial, in Part 2 of the trial, 65 patients were randomized to receive INOpulse doses of eitheriNO25 or iNO75. The long-term extension analysis was performed after patients had completed between 16 and 32 months of INOpulse treatment, and datafrom the long-term extension analysis was compared to baseline measurements taken at the beginning of Part 1 of the trial. All patients in the trial were on atleast one approved PAH therapy, and most were on two or three PAH therapies.The long-term extension analysis showed the following:•Patients on LTOT in the iNO 75 dose treatment arm who remained on INOpulse therapy for at least 12 hours a day had a mean improvement of 55.2meters as compared to baseline (n=7).•Patients on LTOT in the iNO 75 dose treatment arm who remained on INOpulse therapy for less than 12 hours a day showed a mean decrease of 18.0meters as compared to baseline (n=6).•Patients on LTOT in the iNO 25 dose treatment arm had a mean decrease of 43.7 meters from baseline (n=12).For patients in the long-term extension study, no significant safety issues have been found with no reports of methemoglobin elevation and no adjudicatedcases of pulmonary rebound. Only two SAEs have been reported as possibly related, with these subjects continuing on iNO therapy.Pivotal Phase 3 Clinical TrialsAfter reaching agreement with the FDA and EMA on our Phase 3 protocol, we are moving forward with our Phase 3 development program. InSeptember 2015, the FDA issued a SPA for our Phase 3 PAH program for INOpulse, which will include two confirmatory clinical trials. The INOvation-1 trialhas been initiated with the first patient enrolled in June 2016. During January 2017, we received confirmation from the FDA of its acceptance of allmodifications proposed by us to our Phase 3 program. Under the newly modified Phase 3 program, the ongoing one-year INOvation-1 study, and a secondconfirmatory randomized withdrawal study with approximately 40 patients who will be crossing over from the INOvation-1 study, can serve as the twoadequate and well-controlled studies to support a NDA filing for INOpulse in PAH subjects on LTOT.The original Phase 3 program called for two studies, the INOvation-1 study (n=188; placebo arm and iNO 75 arm), followed by the INOvation-2study (n=282; placebo arm, iNO 50 arm and iNO 75 arm). With the approved modifications to the Phase 3 program, the INOvation-2 study will be replacedwith the randomized withdrawal study, a much smaller study in approximately 40 subjects over a four-month enrichment period and two month randomizedwithdrawal.In the modified Phase 3 program, following completion of INOvation-1, subjects will receive at least four months of active, open-label iNO treatmentwith a dose of 75 mcg/kg IBW/hr (iNO75). Those subjects who demonstrate ≥ 30 meter improvement in 6MWD, the primary endpoint of INOvation-1, andcan tolerate the iNO, will constitute an "enriched" population of iNO responders who will be randomized to either placebo or iNO75 in the withdrawal study.Changes in clinical status (defined as clinical worsening) within an individual patient during the randomized withdrawal period will provide the12necessary evidence of whether the improvements observed during the enrichment phase were related or non-related to iNO therapy. The proposed studydesign, therefore, provides the formal confirmatory evidence of whether iNO at a dose of 75 mcg/kg IBW/hr delivered via the INOpulse delivery device for upto 24 hours per day is efficacious in subjects with PAH concomitantly using approved PAH medication and LTOT.Both studies include an interim analysis approximately half-way through each study to assess for efficacy and futility. The interim analysis for theINOvation-1 study also includes a potential sample size reassessment. INOpulse for PH-COPD We are developing INOpulse for PH-COPD to address a significant unmet medical need that we believe is often overlooked in everyday clinicalpractice because of the lack of available therapy. PH is more prevalent among those COPD patients who have advanced loss of respiratory function and lowperipheral blood oxygen levels requiring treatment with LTOT. The co-morbidity of PH in these patients leads to cardiovascular complications from theadded strain on the right ventricle of the heart. Current drug therapies for COPD are targeted to relieve the symptoms and complications of the respiratorycomponent of the disease. Unlike these therapies, INOpulse is directed at treating the cardiovascular complications of PH-COPD. We believe PH-COPDpatients on LTOT who are at risk for cardiovascular complications could benefit from use of INOpulse in addition to any respiratory benefits that result fromtheir existing treatments.Disease Background and Market OpportunityCOPD is a progressive disease caused by chronic inflammation and destruction of the airways and lung tissue. While COPD is primarily a respiratorydisease, over time, as the disease progresses, the chronic pulmonary restrictions and resulting deprivation of adequate oxygen, or hypoxia, can contribute tovasoconstriction in the pulmonary arterial bed. In addition, COPD patients can have deficiency in endogenous nitric oxide production in their lungs, whichcan worsen vasoconstriction. This pulmonary vasoconstriction puts pressure on the right side of the heart, making it less able to cope with stressors andpotentially leading to progressive cardiac dilation, heart failure and death. This cardiovascular component of COPD is, we believe, often overlooked despitepulmonologists’ general awareness of the problem, in part because there are no specific therapies for the condition in these patients. While it is widelybelieved that the cardiovascular complications of COPD occur only in the advanced stage of the disease as a consequence of chronic hypoxemia, recentfindings demonstrate an earlier involvement of the cardiovascular system in this disease.In 2010, Datamonitor estimated that approximately 12 million patients in the United States were being treated for COPD and that over 1.4 million ofthese patients were being treated with LTOT. Based on academic studies, we estimate that 50% of COPD patients on LTOT in the United States have PH.Even though the degree of PH in these patients is milder than in PAH patients, data published in literature suggests that even small elevations in meanpulmonary artery pressure in patients with advanced COPD can impact hospitalization, patient-assessed functional outcomes and mortality. PH is a well-known predictor of increased morbidity and mortality in COPD patients and is associated with poor quality of life, worse clinical outcomes and shortersurvival time. Based on a long-term study completed in 1992 and published in 1995, PH-COPD patients had a four-year survival rate of approximately 50%.By contrast, in this same long-term study, COPD patients with similar pulmonary functions, but without PH, had a four-year survival rate of 80%.The overall COPD market in the United States was estimated to be approximately $32 billion in 2010 with a compounded annual growth rate ofapproximately 4%. We expect INOpulse for PH-COPD, if approved, would be a treated as a specialty drug. Specialty drugs are typically high-costmedications, often ranging in price in the United States from approximately $15,000 to $50,000 per patient per year, used to treat rare or complex conditions,requiring close clinical management, special handling and distribution through specialty pharmacies.Scientific Rationale for Use of INOpulse for PH-COPD The mechanism of action of inhaled nitric oxide in vasodilation at the alveolar smooth muscle in PH-COPD is similar to its action in PAH. Likeendogenous pulmonary nitric oxide, inhaled nitric oxide works by selectively relaxing lung vascular smooth muscles, causing dilation of pulmonary bloodvessels and consequently increased pulmonary blood flow. This reduces the elevated pulmonary artery pressure in patients with PH-COPD.PH-COPD patients generally have hypoxemia as a result of deteriorating lung function, which can be treated with supplemental oxygen therapy.However, these patients are not treated with currently approved PAH-specific drugs because these drugs can worsen hypoxemia. This worsening can occurwhen these drugs, which are systemically bioavailable, cause indiscriminate pulmonary vasodilation, even in poorly ventilated alveoli, resulting in loweraverage blood oxygenation levels. We believe that pulsed nitric oxide, as a locally active selective pulmonary vasodilator, can avoid the indiscriminatevasodilation associated with drugs that are systemically bioavailable. The INOpulse technology, by targeting the delivery of the13pulse to the well ventilated alveoli, has the potential to drop pulmonary arterial pressure while avoiding the lowering of blood oxygen levels.The targeted delivery of inhaled nitric oxide to specific alveoli is important because early trials with continuous-flow inhaled nitric oxide reducedpulmonary arterial pressure in PH-COPD patients but also resulted in lowering of blood oxygen levels. It was postulated that this unwanted effect might beavoided by administering nitric oxide as a brief pulse at the beginning of each breath because well-ventilated alveoli open faster, and a brief early pulsewould only reach these alveoli. As early as 1997, this concept was demonstrated by testing inhaled nitric oxide in PH-COPD patients during exercise, whichallowed the dose to mimic pulse dosing. Recently, data from a computational fluid-flow modeling study we conducted, using high resolution computedtomography scans and computer simulations, supported this hypothesis that early pulsed delivery of nitric oxide could be directed specifically to the well-ventilated alveoli. Clinical Development Program INOpulse for PH-COPD is designated as a drug-device combination by the FDA and is being reviewed by the Division of Cardiovascular and RenalProducts in the Center for Drug Evaluation and Research with consultation from the Division of Pulmonary, Allergy, and Rheumatology Products and theCenter for Devices and Radiological Health. In our IND for PH-COPD, we referenced all of the information in our IND for PAH. The data referenced in ourIND, as well as the years of use of the marketed product, demonstrate that nitric oxide is well tolerated. The FDA has agreed that the IND package is adequatefor supporting Phase 2 clinical development of INOpulse for PH-COPD. The FDA also agreed that no additional pre-clinical studies are needed to supportproduct approval.We completed a randomized, placebo-controlled, double-blind, dose-confirmation Phase 2 clinical trial of INOpulse for PH-COPD in July 2014. Wehave received results from this trial, and have initiated further Phase 2 testing to demonstrate the potential benefit on exercise capacity. In September 2015,an oral presentation of late-breaking data from a clinical trial sponsored by us was presented at the European Respiratory Society International Congress2015 in Amsterdam. The data showed that INOpulse improved vasodilation in patients with PH-COPD. In July 2016, the results were published in theInternational Journal of COPD in an article titled "Pulmonary vascular effects of pulsed inhaled nitric oxide in COPD patients with pulmonary hypertension".Building upon this and other work we have done over recent quarters, we have initiated additional Phase 2 testing for the use of the INOpulse device for PH-COPD patients to evaluate the potential benefit of chronic use on exercise capacity, with the first patient enrolled in October 2016.The initiated Phase 2 study in PH-COPD is an open-label study looking at both vasodilation and exercise capacity on ten COPD patients withpulmonary hypertension who are also on long-term oxygen therapy. The key elements of the study are:•iNO 30 mcg/kg IBW/hr dose for four weeks with a follow-up visit two weeks after discontinuation;•All patients in the trials will be on LTOT;•The primary endpoint is vasodilation in pulmonary arteries measured by high resolution CT scanning (HRCT);•Key secondary endpoint is 6MWD; and•HRCT will be done at baseline and end of four weeks with 6MWT performed at baseline, two weeks, four weeks and six weeks (two weeks afterdiscontinuation of therapy).INOpulse for PH-IPFWe are also developing INOpulse for the treatment of PH-IPF. IPF is a progressive disease of unknown etiology associated with growth of fibrotictissue in the lungs causing hypoxemia, dyspnea, fatigue and cough. The median survival is only two to three years. Based on academic studies, we estimatethe prevalence of IPF in the United States at approximately 90,000 patients, with 20-40% suffering from pulmonary hypertension. PH with IPF increasesmortality. The presence of PH correlates most closely with the need for oxygen therapy. While there are two recently approved treatments for IPF, there arecurrently no approved therapies for PH-IPF. The two therapies that are currently approved for IPF, nintedanib and perfinidone cost approximately $100,000per year.iNO may improve outcomes in PH-IPF by both improving V/Q matching with increases in arterial oxygenation and by lowering pulmonary arterypressures. It has been shown (Yoshida et al) that inhalation of nitric oxide significantly reduced the mean pulmonary arterial pressure and the pulmonaryvascular resistance as compared with room air alone. However, the arterial oxygen tension (PaO2) did not improve. The combined inhalation of nitric oxideand oxygen produced a significant decrease of pulmonary arterial pressure (p<0.01) as well as an improvement (p<0.05) in PaO2 as compared to oxygenalone. These findings support the potential for the combined use of nitric oxide and oxygen for treating idiopathic pulmonary fibrosis patients withpulmonary hypertension.Clinical Development Program14A Phase 2 study in PH-IPF has been initiated looking at both vasodilation and exercise capacity on four IPF patients with pulmonary hypertensionwho are also on long-term oxygen therapy. The study is made up of an acute dose titration phase, where the optimal iNO dose is determined viahemodynamic measurements. This is followed by a chronic phase (four weeks on the optimal iNO dose then two week withdrawal period) to assess impact onexercise capacity measured via 6MWD. The study is open label and incorporates high resolution tomography (HRCT) to visualize vasodilation both on andoff iNO. The study was modified from the original design to incorporate the dose titration, allowing for a better understanding of the iNO dose sensitivity forPH-IPF patients. INOpulse for Other Pulmonary Hypertension Conditions PH disease is often classified according to the WHO classification system which groups patients with PH according to the underlying etiologies, orcauses, of the PH. In this system, PAH is defined as Group 1 and PH-COPD is classified under Group 3, PH due to lung disease and/or hypoxemia. We believethe mechanism of action of inhaled nitric oxide as a pulmonary vasodilator, and thus INOpulse, can be effective in treating PH related to other conditions,including CTEPH, PH associated with sarcoidosis and PH associated with pulmonary edema from high altitude sickness.In 2013, riociguat (Adempas) was the first drug therapy approved for treating CTEPH, although other PAH medications are sometimes used to treatthis condition. Patients with sarcoidosis are often treated with steroids or other anti-inflammatory medications, however, there are no therapies approved totreat the PH associated with this disease. Pulmonary edema from high altitude sickness is typically treated with oxygen therapy, however, there are no currenttreatments for PH associated with this disease.Our current license from Ikaria covers the development of the Bellerophon indications as noted above.BCMIn December 2011 , we initiated a clinical trial of BCM, which we refer to as our PRESERVATION I trial, and completed enrollment in December 2014.Top-line results from the randomized, double-blind, placebo-controlled clinical trial were announced in July 2015. Topline results showed no statisticallysignificant treatment differences between patients treated with BCM and patients treated with placebo for both the primary and the secondary endpoints.Following the results, we are considering further exploratory work but we do not intend to proceed with further clinical development of BCM at this pointuntil and unless we can determine an alternative path forward. We continue to maintain the patent portfolio, including the composition of matter and methodmanufacturing patents that we have in-licensed from BioLineRx Ltd. In addition, we continue with trial management and close out activities for thePRESERVATION I trial in accordance with GCP requirements.Relationship with Ikaria after the Spin-OutThe development of our programs was initiated under the leadership of our scientific and development team while at Ikaria. Ikaria’s lead product,INOmax, is an inhaled nitric oxide product used for treatment of persistent PH of the newborn. Our understanding of the medical applications of nitric oxideand associated delivery devices, as well as our innovative approach to the pulsed delivery of nitric oxide, originated at Ikaria.In October 2013, Ikaria completed an internal reorganization of certain assets and subsidiaries, in which it transferred to us exclusive worldwideroyalty-free rights to develop and commercialize pulsed nitric oxide in PAH, PH-COPD and PH-IPF. In November 2015, we entered into an amendment to ourexclusive cross-license, technology transfer and regulatory matters agreement with Ikaria that included a royalty equal to 3% of net sales of any commercialproducts for PAH. Following the internal reorganization, in February 2014, Ikaria distributed all of our then outstanding units to its stockholders through thepayment of a special dividend on a pro rata basis based on each stockholder’s ownership of Ikaria capital stock. We refer to Ikaria’s distribution of our thenoutstanding units to its stockholders as the Spin-Out.Shortly after the Spin-Out, Ikaria was acquired by entities affiliated with Madison Dearborn Partners. On April 16, 2015, Mallinckrodt plc, orMallinckrodt, announced that it had completed its acquisition of Ikaria.In connection with the Spin-Out, we entered into several agreements with Ikaria providing for, among other things, the provision of transitionservices, the cross license of certain intellectual property, commitments not to compete, the manufacture and supply of the INOpulse drug and device andcertain employee matters. Transition Services Agreement and 2015 Services AgreementIn February 2014 and July 2015, we entered into a transition services agreement and an amendment to the transition services agreement,respectively, with Ikaria, which we refer to as the TSA. Pursuant to the terms and conditions of the TSA,15Ikaria had agreed to use commercially reasonable efforts to provide certain services to us until February 2016. In exchange for the services provided by Ikariapursuant to the TSA, we paid to Ikaria a service fee in the amount of $772,000 per month and reimbursed Ikaria for any out of pocket expenses and any taxesimposed on Ikaria in connection with the provision of services under the TSA. The termination of these services was accelerated to September 30, 2015 aspart of the amendment to the agreement entered in July 2015.Under our additional services agreement with Ikaria, or the 2015 Services Agreement, which became effective on January 1, 2015, Ikaria provided tous certain information technology and device servicing services. In exchange for the services provided by Ikaria pursuant to the 2015 Services Agreement, wepaid to Ikaria fees that totaled, in the aggregate, approximately $0.2 million. We also received payments of $1.7 million from Ikaria in connection with the2015 Services Agreement for using commercially reasonable efforts to provide certain services to Ikaria, including services related to regulatory matters, drugand device safety, clinical operations, biometrics and scientific affairs. In July 2015, we entered into an amendment to the 2015 Services Agreementadvancing the termination date from February 8, 2016 to September 30, 2015.Exclusive Cross-License, Technology Transfer and Regulatory Matters Agreement In February 2014, we entered into an exclusive cross-license, technology transfer and regulatory matters agreement with Ikaria. Pursuant to the terms ofthe license agreement, Ikaria granted to us a fully paid-up, non-royalty bearing, exclusive license under specified intellectual property rights controlled byIkaria to engage in the development, manufacture and commercialization of nitric oxide, devices to deliver nitric oxide and related services for or inconnection with out-patient, chronic treatment of patients with PAH, PH-COPD or PH-IPF. In July 2015, we entered into an amendment to the licenseagreement to expand the scope of our license to allow us to develop our INOpulse program for the treatment of three additional indications: CTEPH, PHassociated with sarcoidosis and PH associated with pulmonary edema from high altitude sickness. Subject to the terms set forth therein, the amendment to thelicense agreement also provides that the Company will pay Ikaria a royalty equal to 5% of net sales of any commercialized products for the three additionalindications. In November 2015, we entered into an amendment to our exclusive cross-license, technology transfer and regulatory matters agreement withIkaria that included a royalty equal to 3% of net sales of any commercial products for PAH.We have granted to Ikaria a fully paid-up, non-royalty-bearing, exclusive license under specified intellectual property rights that we control toengage in the development, manufacture and commercialization of products and services for or used in connection with the diagnosis, prevention ortreatment, whether in- or out-patient, of certain conditions and diseases other than the Bellerophon indications and for the use of nitric oxide to treat orprevent conditions that are primarily managed in the hospital, which we refer to collectively as the Ikaria nitric oxide business.We have agreed that, during the term of the license agreement, we will not, without the prior written consent of Ikaria, grant a sublicense under anyof the intellectual property licensed to us under the license agreement to any of our affiliates or any third party, in either case that directly or indirectlycompetes with the Ikaria nitric oxide business. We have also agreed that we will include certain restrictions in our agreements with customers of our productsto ensure that such products will only be used for the Bellerophon indications.The license agreement will expire on a product-by-product basis for products for a specific Bellerophon indication at such time as we are no longerdeveloping or commercializing any product for such indication. The license agreement may be terminated by either party in the event an act or order of acourt or governmental authority prohibits either party from substantially performing under the license agreement. Either party may also terminate the licenseagreement in the event of an uncured material breach by the other party or in the event the other party is insolvent or in bankruptcy proceedings. Ikaria mayalso terminate the license agreement if we or any of our affiliates breach the agreements not to compete described below, or if we or any successor to ourrights under the license agreement markets a generic nitric oxide product that is competitive with INOmax. Under certain circumstances, if the licenseagreement is terminated, the licenses granted to Ikaria by us will survive such termination.Ikaria retains the right to develop and commercialize inhaled nitric oxide products, including pulsed products, in all indications other than theBellerophon indications. Agreements Not to Compete In September 2013, October 2013 and February 2014, we and each of our subsidiaries entered into an agreement not to compete with Ikaria, each ofwhich was amended in July 2015. We refer to these agreements collectively as the agreements not to compete. Pursuant to the agreements not to compete, asamended, we and each of our subsidiaries agreed not to engage, anywhere in the world, in any manner, directly or indirectly, until the earlier of five yearsafter the effective date of such16agreement not to compete, as amended, or the date on which Ikaria and all of its subsidiaries are no longer engaged in such business, in:•the development, manufacture, commercialization, promotion, sale, import, export, servicing, repair, training, storage, distribution, transportation,licensing or other handling or disposition of any product or service (including, without limitation, any product or service that utilizes, contains or includesnitric oxide for inhalation, a device intended to deliver nitric oxide or a service that delivers or supports the delivery of nitric oxide), bundled or unbundled,for or used in connection with (a) the diagnosis, prevention or treatment, in both adult and/or pediatric populations, and whether in- or out-patient, of: (i)hypoxic respiratory failure associated with pulmonary hypertension, (ii) pulmonary hypertensive episodes and right heart failure associated withcardiovascular surgery, (iii) bronchopulmonary dysplasia, (iv) the management of ventilation-perfusion mismatch in acute lung injury, (v) the management ofventilation-perfusion mismatch in acute respiratory distress syndrome, (vi) the management of pulmonary hypertension episodes and right heart failure incongestive heart failure, (vii) the management of pulmonary hypertension episodes and right heart failure in pulmonary or cardiac surgery, (viii) themanagement of pulmonary hypertension episodes and right heart failure in organ transplant, (ix) sickle cell vaso-occlusive crisis, (x) hypoxia associated withpneumonia or (xi) ischemia-reperfusion injury or (b) the use of nitric oxide to treat or prevent conditions that are primarily managed in the hospital; or•any and all development, manufacture, commercialization, promotion, sale, import, export, storage, distribution, transportation, licensing, or otherhandling or disposition of any terlipressin or any other product within the pressin family, (a) intended to treat (i) hepatorenal syndrome in any form, (ii)bleeding esophageal varices or (iii) septic shock or (b) for or in connection with the management of low blood pressure.The agreements not to compete expressly exclude the Bellerophon indications.In February 2014, we also entered into drug and device clinical supply agreements and an employee matters agreement with Ikaria. In November2015, we entered into an amendment to the drug supply agreement. See “Manufacturing” below for a description of the drug and device clinical supplyagreements and “Certain Relationships and Related Person Transactions-Relationship with Ikaria” for a description of the employee matters agreement. Manufacturing INOpulse Drug Product In February 2014, we and a subsidiary of Ikaria entered into a drug supply agreement which was subsequently amended in November 2015. Under thisagreement, Ikaria has agreed to use commercially reasonable efforts to supply inhaled nitric oxide for us in our clinical trials, and we have agreed to purchaseour clinical supply of inhaled nitric oxide from Ikaria. We have also granted Ikaria a right of first negotiation in the event that we desire to enter into acommercial supply agreement with a third party for supply of nitric oxide for inhalation. The drug supply agreement will expire on a product-by-productbasis on the date we discontinue clinical development of such product. In addition, either party may terminate the drug supply agreement in the event of anuncured material breach by the other party. Ikaria manufactures pharmaceutical-grade nitric oxide at its facility in Port Allen, Louisiana. This facility, which we believe is operated in compliancewith current Good Manufacturing Practices, or cGMP, is the only FDA-approved site for manufacturing medical nitric oxide in the world. To support business outside of the United States, the Port Allen manufacturing facility has also successfully passed inspections by the EMA, HealthCanada; the Pharmaceutical and Medical Devices Agency, or PMDA, of Japan, and the Korean FDA, or KFDA. The EMA, the Health Protection Branch ofHealth Canada, PMDA and KFDA operate in a similar fashion to the FDA in that each requires submission of a dossier containing substantial evidence ofsafety and effectiveness prior to approval. These agencies’ monitoring of safety in a post-marketing setting also is similar to that of the FDA. The filling process has been developed by Ikaria as a high-throughput batch fill process that leverages several technologies that Ikaria hasdeveloped, and we have licensed, to fill the cartridge (containers) at a higher pressure and purity. This manufacturing system is designed to be modular and can be expanded as needed. The current installed capacity within the Port Allen plant issufficient to support our INOpulse clinical program as currently planned. In addition, the plant has the capacity to expand to meet additional demand. Wehave a license from Ikaria to use this fill process technology to work with additional companies, as needed, to produce the final cartridge. Commercial supplymanufacturing can be supported with additional units installed at the Port Allen site or other regional locations, by Ikaria or other manufacturers, asdetermined by distribution requirements. For our clinical trials, Ikaria can supply and ship product from the Port Allen site and the current17cartridges have a shelf life of at least two years. We are testing the finished product to potentially establish a shelf life of up to three years. INOpulse Drug Delivery Systems In February 2015, we entered into an agreement with Flextronics Medical Sales and Marketing Ltd., a subsidiary of Flextronics International Ltd., orFlextronics, to manufacture and service the INOpulse device. PAH patients have the potential for rebound PH, which is a sudden and serious increase in pulmonary arterial pressure that results from therapywithdrawal. However, in the Phase 2 trial, all patients were tested for rebound PH and we found no adjudicated cases of rebound PH with this testing. Subjects in our PAH trials are all on at least one background specific PAH therapy, the majority being on two or more PAH therapies. These backgroundtherapies likely protect against rebound. Though the likelihood of rebound PH is very low, all patients with PAH are provided with a backup system. Competition The biotechnology and pharmaceutical industries are highly competitive. There are many pharmaceutical companies, biotechnology companies,public and private universities and research organizations actively engaged in the research and development of products that may be similar to our products.In addition, other companies are increasingly looking at cardiopulmonary indications as a potential opportunity. It is possible that the number of companiesseeking to develop products and therapies for the treatment of unmet needs in our target markets will increase. Our competitors, either alone or with their strategic partners, may have substantially greater financial, technical and human resources than we do andsignificantly greater experience in the discovery and development of product candidates, obtaining FDA and other regulatory approvals of products and thecommercialization of those products. Accordingly, our competitors may be more successful than we may be in obtaining approval for therapies and achievingwidespread market acceptance. We anticipate that we will face intense and increasing competition as new drugs and advanced technologies becomeavailable. Currently, we believe there are 14 drugs approved for the treatment of PAH, within the following categories: prostacyclin and prostacyclin analogs(including Flolan (epoprostenol), which is marketed by GlaxoSmithKline, Tyvaso (treprostinil), Orenitram (treprostinil) and Remodulin (treprostinil), whichare marketed by United Therapeutics Corporation, Ventavis (iloprost) and Veletri (epoprostenol), which are marketed by Actelion Pharmaceuticals US, Inc.,or Actelion, and Beraprost (which is a generic available in Asian markets), phosphodiesterase type-5 inhibitors (including Adcirca (tadalafil), which ismarketed by United Therapeutics Corporation, and Revatio (sildenafil), which is marketed by Pfizer Inc.), endothelin receptor antagonists (including Letairis(ambrisentan), which is marketed by Gilead Sciences, Inc., and Opsumit (macitentan) and Tracleer (bosentan), which are marketed by Actelion) and a solubleguanylate cyclase stimulator (Adempas (riociguat), which is marketed by Bayer HealthCare Pharmaceuticals Inc.). The most recent addition to the list isUptravi (selexipag), a selective prostacyclin receptor agonist, which is marketed by Actelion and was approved by the FDA in December 2015.There are also other treatments for PAH in various phases of development, including other nitric oxide generation and delivery systems such asGeNOsyl™ (being developed by GeNO LLC) and a nebulized formulation of nitrite (being developed by Mast Therapeutics) both in Phase 2 development.Further, Insmed, Inc. is developing an investigational, sustained-release, inhaled treprostinil prodrug, SteadyMed Therapeutics, Inc., or Steady Med, isdeveloping Trevyent™ which delivers treprostinil using SteadyMed's PatchPump technology and Novartis Pharmaceuticals Corporation is developingQCC374 an inhaled prostacyclin receptor agonist.Currently, there are no approved therapies for treating PH-COPD, and the only generally accepted treatments are LTOT, pulmonary rehabilitation andlung transplant, and we are not aware of any therapies for PH-COPD in advanced clinical development. Currently, there are no approved therapies for treatingPH-IPF and we are not aware of any therapies for PH-IPF in advanced clinical development. Patents and Proprietary RightsWe strive to protect the proprietary technologies that we believe are important to our business, including seeking and maintaining patent protectionintended to protect, for example, our product candidates, related technologies and/or other aspects of the inventions that are important to our business. Ourowned and licensed patents and patent applications cover patentable subject matter from composition of matter, methods of use, devices and devicecomponents, critical safety features18and design components with respect to INOpulse. However, patent protection is not available for the composition of matter of the active pharmaceuticalingredients in INOpulse since nitric oxide is a naturally occurring molecule.Actual protection afforded by a patent, which can vary from country to country, depends on the type of patent, the scope of its coverage and theavailability of legal remedies in the country. We also rely on trade secrets and careful monitoring of our proprietary information to protect aspects of ourbusiness that are not amenable to, or that we do not consider appropriate for, patent protection.We plan to continue to expand our intellectual property estate by filing patent applications directed to inventions which provide additional patentprotection for our product offering, for instance, device enhancements, safety features and manufacturing processes. Our success will depend significantly onour ability to obtain and maintain patent and other proprietary protection for commercially important technology, inventions and know-how related to ourbusiness; defend and enforce our patents; maintain our licenses to use intellectual property owned by third parties; preserve the confidentiality of our tradesecrets; and operate without infringing the valid and enforceable patents and other proprietary rights of third parties. We also consider know-how, continuingtechnological innovation and in-licensing opportunities to develop, strengthen and maintain our proprietary positions.A third party may hold intellectual property, including patent rights that are important or necessary to the development of our programs. It may benecessary for us to use the patented or proprietary technology of third parties to commercialize our product candidates, in which case we would be required toobtain a license from these third parties on commercially reasonable terms, or our business could be harmed, possibly materially. For example, if we want toexpand the indications for which we could develop and commercialize pulsed nitric oxide beyond the Bellerophon indications, we will need to obtain alicense from Ikaria.The patent positions of therapeutics companies like us are generally uncertain and involve complex legal, scientific and factual questions. Inaddition, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and patent scope can be reinterpreted by thecourts after issuance. Moreover, many jurisdictions permit third parties to challenge issued patents in administrative proceedings which may result in furthernarrowing or even cancellation of patent claims. Consequently, we do not know whether any of our product candidates will be protectable or remainprotected by enforceable patents. We cannot predict whether the patent applications we are currently pursuing will issue as patents in any particularjurisdiction or whether the claims of any issued patents will provide sufficient protection from competitors. Any patents that we own or license may bechallenged, narrowed, circumvented or invalidated by third parties.Because patent applications in the United States and certain other jurisdictions are maintained in secrecy for 18 months or potentially even longer,and since publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain of the priority ofinventions covered by pending patent applications. Moreover, we may have to participate in interference proceedings declared by the U.S. Patent andTrademark Office, or USPTO, to determine priority of inventions for any patent applications filed with the USPTO on or before March 15, 2013. Likewise,derivation proceedings may also be declared for any patent filings filed after March 15, 2013.The patents and patent applications that relate to our programs are described below.INOpulse As of March 1, 2017, we hold exclusive licenses from Ikaria to at least 100 patents and pending patent applications in both the United States andforeign countries including Australia, Brazil, Canada, China, Eurasia, Europe, Hong Kong, India, Indonesia, Israel, Japan, Korea, Mexico, the Philippines,Russia, Singapore and South Africa. Certain of these issued patents and patent applications, if issued, will expire as late as 2033. These patent rights havebeen exclusively licensed for the treatment of patients with Bellerophon indications and cover methods of delivery and the drug delivery device, as well asimportant safety features and the ornamental design of the drug delivery device. A primary basis for patent exclusivity is based on pending and issued in-licensed patents directed to proprietary methods of administering pulsedinhaled nitric oxide, as well as a device for delivering the same. At least one patent has been issued in the United States as well as Australia, Canada, China,Europe, Hong Kong, Japan, and Mexico. Patent applications are pending in Australia, Brazil, China, Europe, Hong Kong, Mexico and the United States. This patent family expires as late as 2027 in the United States and in 2026 in the other countries. Another important basis for patent exclusivity is based on an in-licensed portfolio of patents, directed to novel nasal cannula features that we believeare necessary for the accurate, safe and efficacious administration of pulsed nitric oxide. The patent family consists of three issued U.S. patents and pendingapplications in the United States as well as Australia, Brazil, Canada, China, Eurasia, Europe, Hong Kong, Israel, India, Japan, Korea, Mexico and SouthAfrica. One patent application has been allowed in Europe when the patent office issued a Notice of Intention to Grant. Each of these patents and patent19applications, if issued, will expire in 2033 in the United States and abroad. Another in-licensed patent family relates to features of the drug delivery canister necessary for providing drug product for use with our proprietarypulsing drug delivery device. This patent family includes one issued U.S. patent, one issued Japanese patent, one issued Mexican patent, one issuedSingaporean patent, one issued Israeli patent, one issued Chinese patent, one issued Indonesian patent, one issued Korean patent, one issued Russian patent,one issued Philippine patent and three issued Australian patents, as well as pending patent applications in the United States, Brazil, Canada, China, Europe,Hong Kong, India, Israel, Japan, Korea, Mexico, Russia and Singapore. The patent application in Europe has been recently allowed when the patent officeissued a Notice of Intention to Grant. These pending applications, if issued, as well as the non-U.S. issued patents will expire in 2029. The issued U.S. patentwill expire in 2030. Several other patent families directed to device and safety features are issued and pending. Furthermore, design patents covering the ornamentaldesigns of the intended commercial device and clinical device have been granted. In addition, the FDA has granted orphan drug designation to our nitric oxide program for the treatment of PAH, which could result in marketingexclusivity of seven years in the United States should this be the first NDA approved for inhaled nitric oxide in this indication. The active ingredient, nitricoxide, was previously approved by the FDA as a drug in a separate clinical application. Accordingly, any related patent rights will not be eligible for a patentterm extension under relevant provisions of the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Act. Patent Term The base term of a U.S. patent is 20 years from the filing date of the earliest-filed non-provisional patent application from which the patent claimspriority. The term of a U.S. patent can be lengthened by patent term adjustment, which compensates the owner of the patent for administrative delays at theUSPTO. In some cases, the term of a U.S. patent is shortened by a terminal disclaimer that reduces its term to that of an earlier-expiring patent. The term of a U.S. patent may be eligible for patent term extension under the Hatch-Waxman Act to account for at least some of the time the drug ordevice is under development and regulatory review after the patent is granted. With regard to a drug or device for which FDA approval is the first permittedmarketing of the active ingredient, the Hatch-Waxman Act allows for extension of the term of one U.S. patent. Thus, patent term extension is not available forINOpulse since the active moiety is nitric oxide, which is already subject to an approved NDA. The extended patent term cannot exceed the shorter of fiveyears beyond the non-extended expiration of the patent or 14 years from the date of the FDA approval of the drug or device. Some foreign jurisdictions haveanalogous patent term extension provisions that allow for extension of the term of a patent that covers a device approved by the applicable foreign regulatoryagency. Trade Secrets In addition to patents, we rely on trade secrets and know-how to develop and maintain our competitive position. We typically rely on trade secrets toprotect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection. For example, elements of themanufacture of our products are based on trade secrets and know-how that are not publicly disclosed. We protect trade secrets and know-how by establishingconfidentiality agreements and invention assignment agreements with our employees, consultants, scientific advisors, contractors and commercial partners.These agreements provide that all confidential information developed or made known during the course of an individual or entity’s relationship with us mustbe kept confidential during and after the relationship. These agreements also provide that all inventions resulting from work performed for us or relating toour business and conceived or completed during the period of employment or assignment, as applicable, shall be our exclusive property. In addition, we takeother appropriate precautions, such as physical and technological security measures, to guard against misappropriation of our proprietary technology by thirdparties. Trademarks We also seek trademark protection where available and when appropriate. The symbol ™ indicates a common law trademark. Other service marks,trademarks and trade names appearing in this Annual Report on Form 10-K are the property of their respective owners. Government Regulation Government authorities in the United States, at the federal, state and local level, and in other countries and jurisdictions,20including the European Union, extensively regulate, among other things, the research, development, testing, manufacture, quality control, clearance,approval, packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, marketing, post-approval monitoring and reporting, and importand export of pharmaceutical products and medical devices. The processes for obtaining marketing approvals in the United States and in foreign countriesand jurisdictions, along with subsequent compliance with applicable statutes and regulations and other regulatory authorities, require the expenditure ofsubstantial time and financial resources. Review and Approval of Drugs in the United States In the United States, the FDA regulates drugs under the Food, Drug, and Cosmetic Act, or FDCA, and implementing regulations. The process ofobtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations requires theexpenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product developmentprocess, approval process or after approval may subject an applicant and/or sponsor to a variety of administrative or judicial sanctions, including refusal bythe FDA to approve pending applications, withdrawal of an approval, imposition of a clinical hold, issuance of warning letters and other types of letters,product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution,disgorgement of profits, or civil or criminal investigations and penalties brought by the FDA and the Department of Justice or other governmental entities. Our product candidates must be approved by the FDA before they may be legally marketed in the United States. An applicant seeking approval tomarket and distribute a new drug product in the United States must typically undertake the following:• completion of pre-clinical laboratory tests, animal studies and formulation studies in compliance with applicable FDA’s good laboratory practice,or GLP, regulations;• submission to the FDA of an IND which must take effect before human clinical trials may begin;•approval by an independent institutional review board, or IRB, at each clinical site before a clinical trial may be initiated at that site;• performance of adequate and well-controlled human clinical trials in accordance with good clinical practices, or GCP, to establish the safety andefficacy of the proposed drug product for each indication;• preparation and submission to the FDA of an NDA;• review of the product by an FDA advisory committee, where appropriate or if applicable;• satisfactory completion of one or more FDA inspections of the manufacturing facility or facilities at which the product, or components thereof, areproduced to assess compliance with cGMP requirements and to assure that the facilities, methods and controls are adequate to preserve theproduct’s identity, strength, quality and purity;• payment of user fees and securing FDA approval of the NDA; and• compliance with any post-approval requirements, including Risk Evaluation and Mitigation Strategies, or REMS, and post-approval studiesrequired by the FDA. Pre-Clinical Studies Pre-clinical studies include laboratory evaluation of the purity and stability of the manufactured drug substance or active pharmaceutical ingredientand the formulated drug or drug product, as well as in vitro and animal studies to assess the toxicity, safety and activity of the drug for initial testing inhumans and to establish a rationale for therapeutic use. The conduct of pre-clinical and other non-clinical studies is subject to federal regulations andrequirements, including GLP regulations. The results of the pre-clinical tests, together with manufacturing information, analytical data, any available clinicaldata or literature and plans for clinical trials, among other things, are submitted to the FDA as part of an IND. Companies usually must complete some long-term pre-clinical testing, such as animal tests of reproductive adverse events and carcinogenicity, andmust also develop additional information about the chemistry and physical characteristics of the drug and finalize a process for manufacturing the drug incommercial quantities in accordance with cGMP requirements. The21manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other things, the manufacturer mustdevelop methods for testing the identity, strength, quality and purity of the final drug product. Additionally, appropriate packaging must be selected andtested and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its shelf life. Human Clinical Trials in Support of an NDA Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators inaccordance with GCP requirements, which include, among other things, the requirement that all research subjects provide their informed consent in writingbefore their participation in any clinical trial. Clinical trials are conducted under written protocols detailing, among other things, the objectives of theclinical trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A protocol for each phase of a clinical trial and anysubsequent protocol amendments must be submitted to the FDA as part of the IND. An IND automatically becomes effective 30 days after receipt by the FDA,unless before that time the FDA raises concerns or questions related to the initial proposed clinical trial and places the trial on clinical hold. In such a case,the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. Accordingly, submission of an IND may or may notresult in the FDA allowing clinical trials to commence. In addition, an IRB representing each institution participating in the clinical trial must review and approve the plan for any clinical trial before itcommences at that institution, and the IRB must conduct continuing review at least annually. The IRB must review and approve, among other things, thestudy protocol and informed consent information to be provided to study subjects. An IRB must operate in compliance with FDA regulations. A sponsor who wishes to conduct a clinical trial outside the United States may, but need not, obtain FDA authorization to conduct the clinical trialunder an IND. If a foreign clinical trial is not conducted under an IND, the sponsor may submit data from the clinical trial to the FDA in support of an NDA orIND so long as the clinical trial is conducted in compliance with GCP, and the FDA is able to validate the data from the trial through an onsite inspection ifthe agency deems it necessary. Human clinical trials are typically conducted in three sequential phases, which may overlap or be combined:• Phase 1: The drug is initially introduced into a small number of healthy human subjects or patients with the target disease (e.g., cancer) orcondition and tested for safety, dosage tolerance, absorption, metabolism, distribution, excretion and, if possible, to gain an early indication of itseffectiveness and to determine optimal dosage.•Phase 2: The drug is administered to a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate theefficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage.• Phase 3: Phase 3 clinical trials are commonly referred to as “pivotal” studies, which typically denotes a clinical trial which is intended to presentthe data that the FDA or other relevant regulatory agency will use to determine whether or not to approve a drug. In Phase 3 clinical trials, the drugis administered to an expanded patient population, generally at geographically dispersed clinical trial sites, in well-controlled clinical trials togenerate enough data to statistically evaluate the efficacy and safety of the product for approval, to establish the overall risk-benefit profile of theproduct, and to provide adequate information for the labeling of the product. Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if SAEs occur. Phase 1,Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, or at all. Furthermore, the FDA or the sponsor may suspendor terminate a clinical trial at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk.Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’srequirements or if the drug has been associated with unexpected serious harm to patients. The FDA will typically inspect one or more clinical sites to assurecompliance with GCP and the integrity of the clinical data submitted. In addition, the sponsor of a clinical trial must register and post information about thetrial on the National Institutes of Health's clinicaltrials.gov website. Section 505(b)(2) NDAs NDAs for most new drug products are based on two full, or pivotal, clinical trials that must contain substantial evidence of the safety and efficacy ofthe proposed new product. These applications are submitted under Section 505(b)(1) of the FDCA. The FDA is, however, authorized to approve an alternativetype of NDA under Section 505(b)(2) of the FDCA. This type of22application allows the applicant to rely, in part, on the FDA’s previous findings of safety and efficacy for a similar product, or published literature.Specifically, Section 505(b)(2) applies to NDAs for a drug for which the investigations made to show whether or not the drug is safe for use and effective inuse and relied upon by the applicant for approval of the application “were not conducted by or for the applicant and for which the applicant has not obtaineda right of reference or use from the person by or for whom the investigations were conducted.” Thus, Section 505(b)(2) authorizes the FDA to approve an NDA based on safety and effectiveness data that were not developed by the applicant. NDAssubmitted under Section 505(b)(2) may provide an alternate and potentially more expeditious pathway to FDA approval for new or improved formulations ornew uses of previously approved products. If the 505(b)(2) applicant can establish that reliance on the FDA’s previous approval is scientifically appropriate,the applicant may eliminate the need to conduct certain pre-clinical studies or clinical trials of the new product. The FDA may also require companies toperform additional studies or measurements to support the change from the approved product. The FDA may then approve the new drug candidate for all orsome of the label indications for which the referenced product has been approved, as well as for any new indication sought by the Section 505(b)(2) applicant. Submission of an NDA to the FDA Assuming successful completion of clinical trials and other requirements, the results of the non-clinical studies and clinical trials, together withdetailed information relating to the product’s chemistry, manufacture, controls and proposed labeling, among other things, are submitted to the FDA as partof an NDA requesting approval to market the drug product for one or more indications. Under federal law, the submission of most NDAs is additionallysubject to an application user fee, currently exceeding $2.0 million, and the sponsor of an approved NDA is also subject to annual product and establishmentfees, currently exceeding $97,000 per product and $512,000 per establishment. These fees are typically increased annually, although for fiscal year 2017they decreased. The FDA conducts a preliminary review of an NDA within 60 days of its receipt and informs the sponsor by the 74th day after the FDA’s receipt of thesubmission whether the application will be filed because it is sufficiently complete to permit substantive review. The FDA may request additionalinformation rather than accept an NDA for filing. In this event, the application must be resubmitted with the additional information. The resubmittedapplication is also subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantivereview. The FDA has agreed to specified performance goals in the review process of NDAs. Most such applications are meant to be reviewed within tenmonths from the date of filing, and most applications for “priority review” products are meant to be reviewed within six months of filing. The review processmay be extended by the FDA for various reasons, including for three additional months to consider new information or clarification provided by theapplicant to address an outstanding deficiency identified by the FDA following the original submission. Before approving an NDA, the FDA typically will inspect the facility or facilities where the product is or will be manufactured. These pre-approvalinspections may cover all facilities associated with an NDA submission, including drug component manufacturing (such as Active PharmaceuticalIngredients), finished drug product manufacturing, and control testing laboratories. The FDA will not approve an application unless it determines that themanufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product withinrequired specifications. Additionally, before approving an NDA, the FDA will often inspect one or more clinical sites to assure compliance with GCP. The FDA may refer an application for a novel drug to an advisory committee or explain why such referral was not made. Typically, an advisorycommittee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as towhether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but itconsiders such recommendations carefully when making decisions.Special Protocol AssessmentA sponsor of an IND may request that the FDA evaluate within 45 days certain protocols and issues relating to the protocols to assess whether theyare adequate to meet scientific and regulatory requirements identified by the sponsor. Such special protocol assessments, or SPAs, may be requested forclinical protocols for Phase 3 trials whose data will form the primary basis for an efficacy claim if the trials had been the subject of discussion at an end-of-Phase 2/pre-Phase 3 meeting with the FDA. If the sponsor and the FDA reach a written agreement regarding the protocol, the SPAs will be considered bindingon the FDA and will not be changed unless the sponsor fails to follow the agreed-upon protocol, data supporting the request are found to be false orincomplete, or the FDA determines that a substantial scientific issue essential to determining the23safety or effectiveness of the drug was identified after the testing began. Even if a SPA is agreed to, approval of the NDA is not guaranteed since a finaldetermination that an agreed-upon protocol satisfies a specific objective, such as the demonstration of efficacy, or supports an approval decision, will bebased on a complete review of all the data in the NDA. Expedited Review and ApprovalThe FDA has various programs, including Fast Track, priority review, and accelerated approval, which are intended to expedite or simplify theprocess for reviewing drugs, and/or provide for approval on the basis of surrogate endpoints. Even if a drug qualifies for one or more of these programs, theFDA may later decide that the drug no longer meets the conditions for qualification or that the time period for FDA review or approval will not be shortened.Generally, drugs that may be eligible for these programs are those for serious or life threatening conditions, those with the potential to address unmet medicalneeds, and those that offer meaningful benefits over existing treatments. For example, Fast Track is a process designed to facilitate the development, andexpedite the review, of drugs to treat serious diseases and fill an unmet medical need. The request may be made at the time of IND submission and generallyno later than the pre BLA or pre NDA meeting. The FDA will respond within 60 calendar days of receipt of the request. Priority review, which is requested atthe time of BLA or NDA submission, is designed to give drugs that offer major advances in treatment or provide a treatment where no adequate therapy existsan initial review within six months as compared to a standard review time of ten months. Although Fast Track and priority review do not affect the standardsfor approval, the FDA will attempt to facilitate early and frequent meetings with a sponsor of a Fast Track designated drug and expedite review of theapplication for a drug designated for priority review. Accelerated approval provides an earlier approval of drugs to treat serious diseases, and that fill anunmet medical need based on a surrogate endpoint, which is a laboratory measurement or physical sign used as an indirect or substitute measurementrepresenting a clinically meaningful outcome. Discussions with the FDA about the feasibility of an accelerated approval typically begin early in thedevelopment of the drug in order to identify, among other things, an appropriate endpoint. As a condition of approval, the FDA may require that a sponsor ofa drug receiving accelerated approval perform post marketing clinical trials to confirm the appropriateness of the surrogate marker trial.In the Food and Drug Administration Safety and Improvement Act, or FDASIA, Congress encouraged the FDA to utilize innovative and flexibleapproaches to the assessment of products under accelerated approval. The law required the FDA to issue related draft guidance within a year after the law’senactment and also promulgate confirming regulatory changes. The FDA published a final guidance on May 30, 2014, entitled “Expedited Programs forSerious Conditions-Drugs and Biologics.” One of the expedited programs added by FDASIA is that for Breakthrough Therapy. A Breakthrough Therapydesignation is designed to expedite the development and review of drugs that are intended to treat a serious condition where preliminary clinical evidenceindicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint(s). A sponsor may requestBreakthrough Therapy designation at the time that the IND is submitted, or no later than at the end of Phase II meeting. The FDA will respond to aBreakthrough Therapy designation request within sixty days of receipt of the request. A drug that receives Breakthrough Therapy designation is eligible forall fast track designation features, intensive guidance on an efficient drug development program, beginning as early as Phase I and commitment from the FDAinvolving senior managers. The FDA has designated over 150 drugs as breakthrough therapies (some were subsequently withdrawn), and over 80 original orsupplemental applications with breakthrough designations have been approved to date. The FDA’s Decision on an NDA On the basis of the FDA’s evaluation of the NDA and accompanying information, including the results of the inspection of the manufacturingfacilities, the FDA may issue an approval letter or a complete response letter. An approval letter authorizes commercial marketing of the product with specificprescribing information for specific indications. A complete response letter generally outlines the deficiencies in the submission and may require substantialadditional testing or information in order for the FDA to reconsider the application. If and when those deficiencies have been addressed to the FDA’ssatisfaction in a resubmission of the NDA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or sixmonths depending on the type of information included. Even with submission of this additional information, the FDA ultimately may decide that theapplication does not satisfy the regulatory criteria for approval. If the FDA approves a product, it may limit the approved indications for use for the product, require that contraindications, warnings or precautions beincluded in the product labeling, require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess the drug’s safety afterapproval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions which can materially affectthe potential market and profitability of the product. In addition, as a condition of approval, the FDA may require an applicant to develop a REMS. REMSuse risk minimization strategies beyond the professional labeling to ensure that the benefits of the product outweigh the potential risks. To determinewhether a REMS is needed, the FDA will consider the size of the population likely to use the product, seriousness of the disease, expected benefit of theproduct, expected duration of treatment, seriousness of known or24potential adverse events, and whether the product is a new molecular entity. REMS can include medication guides, physician communication plans forhealthcare professionals, and elements to assure safe use, or ETASU. ETASU may include, but are not limited to, special training or certification forprescribing or dispensing, dispensing only under certain circumstances, special monitoring, and the use of patient registries. The FDA may require a REMSbefore approval or post-approval if it becomes aware of a serious risk associated with use of the product. The requirement for a REMS can materially affect thepotential market and profitability of a product. The FDA may prevent or limit further marketing of a product based on the results of post-market studies or surveillance programs. After approval, manytypes of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to furthertesting requirements and FDA review and approval. Post-Approval Requirements Drugs manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among otherthings, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion and reporting of adverseexperiences with the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject toprior FDA review and approval. There also are continuing, annual user fee requirements for any marketed products and the establishments at which suchproducts are manufactured, as well as new application fees for supplemental applications with clinical data. In addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register theirestablishments with the FDA and state agencies, and are subject to periodic unannounced inspections by the FDA and these state agencies for compliancewith cGMP and other requirements. Changes to the manufacturing process are strictly regulated and often require prior FDA approval before beingimplemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting and documentation requirementsupon the sponsor and any third-party manufacturers that the sponsor may decide to use. Accordingly, manufacturers must continue to expend time, money,and effort in the area of production and quality control to maintain cGMP compliance. Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or ifproblems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events ofunanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to theapproved labeling to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distributionor other restrictions under a REMS program. Other potential consequences include, among other things:• restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;• fines, warning letters or holds on post-approval clinical trials;• refusal of the FDA to approve pending NDAs or supplements to approved NDAs, or suspension or revocation of product license approvals;• product seizure or detention, or refusal to permit the import or export of products; or• injunctions or the imposition of civil or criminal penalties. The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only forthe approved indications and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulationsprohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability. In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act, or PDMA, which regulates thedistribution of drugs and drug samples at the federal level, and sets minimum standards for the registration and regulation of drug distributors by the states.Both the PDMA and state laws limit the distribution of prescription pharmaceutical product samples and impose requirements to ensure accountability indistribution. Abbreviated New Drug Applications for Generic Drugs 25In 1984, with passage of the Hatch-Waxman Amendments to the FDCA, Congress authorized the FDA to approve generic drugs that are the same asdrugs previously approved by the FDA under the NDA provisions of the statute. To obtain approval of a generic drug, an applicant must submit anabbreviated new drug application, or ANDA, to the agency. In support of such applications, a generic manufacturer may rely on the pre-clinical and clinicaltesting previously conducted for a drug product previously approved under an NDA, known as the reference listed drug, or RLD. Specifically, in order for an ANDA to be approved, the FDA must find that the generic version is identical to the RLD with respect to the activeingredients, the route of administration, the dosage form, and the strength of the drug. At the same time, the FDA must also determine that the generic drug is“bioequivalent” to the innovator drug. Under the statute, a generic drug is bioequivalent to a RLD if the rate and extent of absorption of the drug do not showa significant difference from the rate and extent of absorption of the listed drug. Upon approval of an ANDA, the FDA indicates whether the generic product is “therapeutically equivalent” to the RLD in its publication “ApprovedDrug Products with Therapeutic Equivalence Evaluations,” also referred to as the “Orange Book.” Physicians and pharmacists consider a therapeuticequivalent generic drug to be fully substitutable for the RLD. In addition, by operation of certain state laws and numerous health insurance programs, theFDA’s designation of therapeutic equivalence often results in substitution of the generic drug without the knowledge or consent of either the prescribingphysician or patient. Under the Hatch-Waxman Amendments, the FDA may not approve an ANDA until any applicable period of non-patent exclusivity for the RLD hasexpired. The FDCA provides a period of five years of non-patent data exclusivity for a new drug containing a new chemical entity. In cases where suchexclusivity has been granted, an ANDA may not be submitted to the FDA until the expiration of five years unless the submission is accompanied by aParagraph IV certification, in which case the applicant may submit its application four years following the original product approval. The FDCA alsoprovides for a period of three years of exclusivity if the NDA includes reports of one or more new clinical investigations, other than bioavailability orbioequivalence studies, that were conducted by or for the applicant and are essential to the approval of the application. This three-year exclusivity periodoften protects changes to a previously approved drug product, such as a new dosage form, route of administration, combination or indication. Hatch-Waxman Patent Certification and the 30-Month Stay Upon approval of an NDA or a supplement thereto, NDA sponsors are required to list with the FDA each patent with claims that cover the applicant’sproduct or an approved method of using the product. Each of the patents listed by the NDA sponsor is published in the Orange Book. When an ANDAapplicant submits its application to the FDA, the applicant is required to certify to the FDA concerning any patents listed for the reference product in theOrange Book, except for patents covering methods of use for which the ANDA applicant is not seeking approval. To the extent that the Section 505(b)(2) applicant is relying on studies conducted for an already approved product, the applicant is required to certify to the FDA concerning any patents listed forthe approved product in the Orange Book to the same extent that an ANDA applicant would. Specifically, the applicant must certify with respect to each patent that:· the required patent information has not been filed;· the listed patent has expired;· the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or· the listed patent is invalid, unenforceable or will not be infringed by the new product. A certification that the new product will not infringe the already approved product’s listed patents or that such patents are invalid or unenforceable iscalled a Paragraph IV certification. If the applicant does not challenge the listed patents or indicate that it is not seeking approval of a patented method ofuse, the ANDA application will not be approved until all the listed patents claiming the referenced product have expired. If the ANDA applicant or 505(b)(2) applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of theParagraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and patent holders may theninitiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within 45 daysafter the receipt of a Paragraph IV certification automatically prevents the FDA from approving the ANDA until the earlier of 30 months after the receipt ofthe Paragraph IV notice, expiration of the patent, or a decision in the infringement case that is favorable to the ANDA applicant.26 Orphan Designation and Exclusivity Under the Orphan Drug Act, FDA may designate a drug product as an “orphan drug” if it is intended to treat a rare disease or condition (generallymeaning that it affects fewer than 200,000 individuals in the United States, or more in cases in which there is no reasonable expectation that the cost ofdeveloping and making a drug product available in the United States for treatment of the disease or condition will be recovered from sales of the product). Acompany must request orphan product designation before submitting a NDA. If the request is granted, FDA will disclose the identity of the therapeutic agentand its potential use. Orphan product designation does not convey any advantage in or shorten the duration of the regulatory review and approval process. If a product with orphan status receives the first FDA approval for the disease or condition for which it has such designation, the product will beentitled to orphan product exclusivity. Orphan product exclusivity means that FDA may not approve any other applications for the same product for the sameindication for seven years, except in certain limited circumstances. Competitors may receive approval of different products for the indication for which theorphan product has exclusivity and may obtain approval for the same product but for a different indication. If a drug or drug product designated as an orphanproduct ultimately receives marketing approval for an indication broader than what was designated in its orphan product application, it may not be entitledto exclusivity. Pediatric Studies and Exclusivity Under the Pediatric Research Equity Act of 2003, a NDA or supplement thereto must contain data that are adequate to assess the safety andeffectiveness of the drug product for the claimed indications in all relevant pediatric subpopulations, and to support dosing and administration for eachpediatric subpopulation for which the product is safe and effective. With enactment of the Food and Drug Administration Safety and Innovation Act, orFDASIA, in 2012, sponsors must also submit pediatric study plans prior to the assessment data. Those plans must contain an outline of the proposed pediatricstudy or studies the applicant plans to conduct, including study objectives and design, any deferral or waiver requests, and other information required byregulation. The applicant, the FDA, and the FDA’s internal review committee must then review the information submitted, consult with each other, and agreeupon a final plan. The FDA or the applicant may request an amendment to the plan at any time. The FDA may, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after approval ofthe product for use in adults, or full or partial waivers from the pediatric data requirements. Additional requirements and procedures relating to deferralrequests and requests for extension of deferrals are contained in FDASIA. Pediatric exclusivity is another type of non-patent marketing exclusivity in the United States and, if granted, provides for the attachment of anadditional six months of marketing protection to the term of any existing regulatory exclusivity, including the non-patent exclusivity. This six-monthexclusivity may be granted if an NDA sponsor submits pediatric data that fairly respond to a written request from the FDA for such data. The data do not needto show the product to be effective in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s request, theadditional protection is granted. If reports of requested pediatric studies are submitted to and accepted by the FDA within the statutory time limits, whateverstatutory or regulatory periods of exclusivity or patent protection cover the product are extended by six months. This is not a patent term extension, but iteffectively extends the regulatory period during which the FDA cannot approve another application. Patent Term Restoration and Extension A patent claiming a new drug product or medical device may be eligible for a limited patent term extension under the Hatch-Waxman Act, whichpermits a patent restoration of up to five years for patent term lost during product development and the FDA regulatory review. The restoration period grantedon a patent covering a new drug product is typically one-half the time between the date a clinical investigation on human beings is begun and thesubmission date of an application for premarket approval of the product, plus the time between the submission date of an application for approval of theproduct and the ultimate approval date. Patent term restoration cannot be used to extend the remaining term of a patent past a total of 14 years from theproduct’s approval date. Only one patent applicable to an approved drug product is eligible for the extension, and the application for the extension must besubmitted prior to the expiration of the patent in question. A patent that covers multiple drugs for which approval is sought can only be extended inconnection with one of the approvals. The USPTO reviews and approves the application for any patent term extension or restoration in consultation with theFDA. 27Review and Approval of Medical Devices in the United States Medical devices in the United States are strictly regulated by the FDA. Under the FDCA a medical device is defined as "an instrument, apparatus,implement, machine, contrivance, implant, -in vitro- reagent, or other similar or related article, including a component, part or accessory which is, amongother things: intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or otheranimals; or intended to affect the structure or any function of the body of man or other animals, and which does not achieve its primary intended purposesthrough chemical action within or on the body of man or other animals and which is not dependent upon being metabolized for the achievement of any of itsprimary intended purposes." This definition provides a clear distinction between a medical device and other FDA regulated products such as drugs. If theprimary intended use of the product is achieved through chemical action or by being metabolized by the body, the product is usually a drug. If not, it isgenerally a medical device. Unless an exemption applies, a new medical device may not be marketed in the United States unless and until it has been cleared through the510(k) premarket notification process, or 510(k), or approved by the FDA pursuant to a premarket approval application, or PMA. The information that mustbe submitted to the FDA in order to obtain clearance or approval to market a new medical device varies depending on how the medical device is classified bythe FDA. Medical devices are classified into one of three classes on the basis of the controls deemed by the FDA to be necessary to reasonably ensure theirsafety and effectiveness. Class I devices are those low risk devices for which reasonable assurance of safety and effectiveness can be provided by adherence to the FDA’sgeneral controls for medical devices, which include applicable portions of the FDA’s Quality System Regulation, or QSR, facility registration and productlisting, reporting of adverse medical events and malfunctions and appropriate, truthful and non-misleading labeling, advertising and promotional materials.Many Class I devices are exempt from premarket regulation; however, some Class I devices require premarket clearance by the FDA through the510(k) premarket notification process. Class II devices are moderate risk devices and are subject to the FDA’s general controls, and any other special controls, such as performance standards,post-market surveillance, and FDA guidelines, deemed necessary by the FDA to provide reasonable assurance of the devices’ safety and effectiveness.Premarket review and clearance by the FDA for Class II devices are accomplished through the 510(k) premarket notification procedure, although someClass II devices are exempt from the 510(k) requirements. Premarket notifications are subject to user fees, unless a specific exemption applies. Class III devices are deemed by the FDA to pose the greatest risk, such as those for which reasonable assurance of the device’s safety and effectivenesscannot be assured solely by the general controls and special controls described above and that are life-sustaining or life-supporting. A PMA must providevalid scientific evidence, typically extensive pre-clinical and clinical trial data and information about the device and its components regarding, among otherthings, device design, manufacturing and labeling. PMA (and supplemental PMAs) are subject to significantly higher user fees than are 510(k) premarketnotifications. Post-Marketing Restrictions and Enforcement After a device is placed on the market, numerous regulatory requirements apply. These include, but are not limited to:•submitting and updating establishment registration and device listings with the FDA;•compliance with the QSR, which requires manufacturers to follow stringent design, testing, control, documentation, record maintenance, includingmaintenance of complaint and related investigation files, and other quality assurance controls during the manufacturing process;• unannounced routine or for-cause device inspections by the FDA, which may include our suppliers’ facilities; and•labeling regulations, which prohibit the promotion of products for uncleared or unapproved or “off-label” uses and impose other restrictions onlabeling; post-approval restrictions or conditions, including requirements to conduct post-market surveillance studies to establish continued safetydata or tracking products through the chain of distribution to the patient level. Under the FDA medical device reporting, or MDR, regulations, medical device manufacturers are required to report to the FDA information that adevice has or may have caused or contributed to a death or serious injury or has malfunctioned in a way that would likely cause or contribute to death orserious injury if the malfunction of the device or a similar device of such28manufacturer were to recur. The decision to file an MDR involves a judgment by the manufacturer. If the FDA disagrees with the manufacturer’sdetermination, the FDA can take enforcement action. Additionally, the FDA has the authority to require the recall of commercialized products in the event of material deficiencies or defects in design ormanufacture. The authority to require a recall must be based on an FDA finding that there is reasonable probability that the device would cause seriousadverse health consequences or death. Manufacturers may, under their own initiative, recall a product if any material deficiency in a device is found. TheFDA requires that certain classifications of recalls be reported to the FDA within ten working days after the recall is initiated. The failure to comply with applicable regulatory requirements can result in enforcement action by the FDA, which may include any of the followingsanctions:• warning letters, fines, injunctions or civil penalties;• recalls, detentions or seizures of products;•operating restrictions;• delays in the introduction of products into the market;• total or partial suspension of production;•delay or refusal of the FDA or other regulators to grant 510(k) clearance or PMA approvals of new products;• withdrawals of 510(k) clearance or PMA approvals; or• in the most serious cases, criminal prosecution. To ensure compliance with regulatory requirements, medical device manufacturers are subject to market surveillance and periodic, pre-scheduled andunannounced inspections by the FDA, and these inspections may include the manufacturing facilities of subcontractors. Review and Approval of Combination Products in the United States Certain products may be comprised of components that would normally be subject to different regulatory requirements, and frequently by differentCenters at the FDA. These products are known as combination products. Specifically, under regulations issued by the FDA, a combination product may be:• a product comprised of two or more regulated components that are physically, chemically, or otherwise combined or mixed and produced as asingle entity;• two or more separate products packaged together in a single package or as a unit and comprised of drug and device products;• a drug or device packaged separately that according to its investigational plan or proposed labeling is intended for use only with an approvedindividually specified drug or device where both are required to achieve the intended use, indication, or effect and where upon approval of theproposed product the labeling of the approved product would need to be changed, e.g., to reflect a change in intended use, dosage form, strength,route of administration, or significant change in dose; or•any investigational drug or device packaged separately that according to its proposed labeling is for use only with another individually specifiedinvestigational drug, device, or biological product where both are required to achieve the intended use, indication, or effect. Under the FDCA, the FDA assigns primary jurisdiction to a lead center at the FDA for review of a combination product. That determination is based onthe “primary mode of action” of the combination product. Thus, if the primary mode of action of a device-drug combination product is attributable to thedrug product, the Center for Drug Evaluation and Research would have primary jurisdiction for the combination product. The FDA's Office of CombinationProducts addresses issues related to combination products and is intended to provide more certainty to the regulatory review process. That office serves as afocal29point for combination product issues for agency reviewers and industry. It is also responsible for developing guidance and regulations to clarify theregulation of combination products, and for assignment of the FDA center that has primary jurisdiction for review of combination products where thejurisdiction is unclear or in dispute. Review and Approval of Drug Products in the European Union In order to market any product outside of the United States, a company must also comply with numerous and varying regulatory requirements of othercountries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercialsales and distribution of drug products. Whether or not it obtains FDA approval for a product, the company will have to obtain the necessary approvals by thecomparable foreign regulatory authorities before it can commence clinical trials or marketing of the product in those countries or jurisdictions. The approvalprocess ultimately varies between and among countries and jurisdictions and can involve additional product testing and additional administrative reviewperiods. The time required to obtain approval in other countries and jurisdictions might differ from and be longer than that required to obtain FDA approval.Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval inone country or jurisdiction may negatively impact the regulatory process in others. Pursuant to the European Clinical Trials Directive, a system for the approval of clinical trials in the European Union, or EU, has been implementedthrough national legislation of the member states. Under this system, an applicant must submit a clinical trial authorization, or CTA, and obtain approvalfrom the competent national authority of a EU member state in which the clinical trial is to be conducted. Furthermore, the applicant may only start a clinicaltrial after a competent ethics committee has issued a favorable opinion. A CTA must be accompanied by an investigational medicinal product dossier withsupporting information prescribed by the European Clinical Trials Directive and corresponding national laws of the member states and further detailed inapplicable guidance documents. In 2018, the existing EU Clinical Trials Directive will be replaced by a Clinical Trial Regulation that will require consistentrules for conducting clinical trials throughout the EU and require that information on the authorization, conduct and results of each clinical trial carried outin the EU be publicly available. To obtain marketing approval of a drug under EU regulatory systems, an applicant must submit a marketing authorization application, or MAA, eitherunder a centralized or decentralized procedure. The centralized procedure provides for the grant of a single marketing authorization by the European Commission that is valid for all EU memberstates. The centralized procedure is compulsory for specific products, including for medicines produced by certain biotechnological processes, productsdesignated as orphan medicinal products, advanced therapy products and products with a new active substance indicated for the treatment of certain diseases.For products with a new active substance indicated for the treatment of other diseases and products that are highly innovative or for which a centralizedprocess is in the interest of patients, the centralized procedure may be optional. Under the centralized procedure, the Committee for Medicinal Products for Human Use, or the CHMP, established at the EMA, is responsible forconducting the initial assessment of a drug. The CHMP is also responsible for several post-authorization and maintenance activities, such as the assessmentof modifications or extensions to an existing marketing authorization. Under the centralized procedure in the EU, the maximum time frame for the evaluationof an MAA is 210 days, excluding clock stops, when additional information or written or oral explanation is to be provided by the applicant in response toquestions of the CHMP. Accelerated evaluation might be granted by the CHMP in exceptional cases, when a medicinal product is of major interest from thepoint of view of public health and in particular from the viewpoint of therapeutic innovation. In this circumstance, the EMA ensures that the opinion of theCHMP is given within 150 days. The decentralized procedure is available to applicants who wish to market a product in various EU member states where such product has not receivedmarketing approval in any EU member states before. The decentralized procedure provides for approval by one or more other, or concerned, member states ofan assessment of an application performed by one member state designated by the applicant, known as the reference member state. Under this procedure, anapplicant submits an application based on identical dossiers and related materials, including a draft summary of product characteristics, and draft labelingand package leaflet, to the reference member state and concerned member states. The reference member state prepares a draft assessment report and drafts ofthe related materials within 210 days after receipt of a valid application. Within 90 days of receiving the reference member state’s assessment report andrelated materials, each concerned member state must decide whether to approve the assessment report and related materials. If a member state cannot approve the assessment report and related materials on the grounds of potential serious risk to public health, the disputedpoints are subject to a dispute resolution mechanism and may eventually be referred to the European Commission, whose decision is binding on all memberstates.30 Review and Approval of Medical Devices in the European Union The EU has adopted numerous directives and standards regulating, among other things, the design, manufacture, clinical trials, labeling, approval andadverse event reporting for medical devices. In the EU, medical devices must comply with the Essential Requirements in Annex I to the EU Medical DevicesDirective (Council Directive 93/42/EEC), or the Essential Requirements. Compliance with these requirements is a prerequisite to be able to affix the CE markof conformity to medical devices, without which they cannot be marketed or sold in the European Economic Area, or EEA, comprised of the EU memberstates plus Norway, Iceland, and Liechtenstein. Actual implementation of these directives, however, may vary on a country-by-country basis. To demonstrate compliance with the Essential Requirements a manufacturer must undergo a conformity assessment procedure, which varies accordingto the type of medical device and its classification. Except for low risk medical devices, where the manufacturer can issue a CE Declaration of Conformitybased on a self-assessment of the conformity of its products with the Essential Requirements, a conformity assessment procedure requires the intervention of athird-party organization designated by competent authorities of a EU country to conduct conformity assessments, or a Notified Body. Notified Bodies areindependent testing houses, laboratories, or product certifiers typically based within the EU and authorized by the European member states to perform therequired conformity assessment tasks, such as quality system audits and device compliance testing. The Notified Body would typically audit and examinethe product’s Technical File and the quality system for the manufacture, design and final inspection of the product before issuing a CE Certificate ofConformity demonstrating compliance with the relevant Essential Requirements.The Medical Device Regulation will impose new requirements on NotifiedBodies and the number of Notified Bodies that will be accredited to audit medical device companies will likely decrease. Medical device manufacturers must carry out a clinical evaluation of their medical devices to demonstrate conformity with the relevant EssentialRequirements. This clinical evaluation is part of the product’s Technical File. A clinical evaluation includes an assessment of whether a medical device’sperformance is in accordance with its intended use, and that the known and foreseeable risks linked to the use of the device under normal conditions areminimized and acceptable when weighed against the benefits of its intended purpose. The clinical evaluation conducted by the manufacturer must alsoaddress any clinical claims, the adequacy of the device labeling and information (particularly claims, contraindications, precautions and warnings) and thesuitability of related Instructions for Use. This assessment must be based on clinical data, which can be obtained from clinical studies conducted on thedevices being assessed, scientific literature from similar devices whose equivalence with the assessed device can be demonstrated or both clinical studies andscientific literature. With respect to implantable devices or devices classified as Class III in the EU, the manufacturer must conduct clinical studies to obtain the requiredclinical data, unless relying on existing clinical data from similar devices can be justified. As part of the conformity assessment process, depending on thetype of devices, the Notified Body will review the manufacturer’s clinical evaluation process, assess the clinical evaluation data of a representative sample ofthe device’s subcategory or generic group, or assess all the clinical evaluation data, verify the manufacturer’s assessment of that data and assess the validityof the clinical evaluation report and the conclusions drawn by the manufacturer. Even after a manufacturer receives a CE Certificate of Conformity enabling the CE mark on it products and the right to sell the products in the EEAcountries, a Notified Body or a competent authority may require post-marketing studies of the products. Failure to comply with such requirements in a timelymanner could result in the withdrawal of the CE Certificate of Conformity and the recall or withdrawal of the subject product from the European market. A manufacturer must inform the Notified Body that carried out the conformity assessment of the medical devices of any planned substantial changes tothe devices which could affect compliance with the Essential Requirements or the devices’ intended purpose. The Notified Body will then assess the changesand verify whether they affect the product’s conformity with the Essential Requirements or the conditions for the use of the devices. If the assessment isfavorable, the Notified Body will issue a new CE Certificate of Conformity or an addendum to the existing CE Certificate of Conformity attesting compliancewith the Essential Requirements. If it is not, the manufacturer may not be able to continue to market and sell the product in the EEA. In the EU, medical devices may be promoted only for the intended purpose for which the devices have been CE marked. Failure to comply with thisrequirement could lead to the imposition of penalties by the competent authorities of the EU Member States. The penalties could include warnings, orders todiscontinue the promotion of the medical device, seizure of the promotional materials and fines. Promotional materials must also comply with various lawsand codes of conduct developed by medical device industry bodies in the EU governing promotional claims, comparative advertising, advertising of medical31devices reimbursed by the national health insurance systems and advertising to the general public. Additionally, all manufacturers placing medical devices in the market in the EU are legally bound to report any serious or potentially serious incidentsinvolving devices they produce or sell to the competent authority in whose jurisdiction the incident occurred. In the EU, manufacturers must comply with theEU Medical Device Vigilance System. Under this system, incidents must be reported to the relevant authorities of the EU countries, and manufacturers arerequired to take Field Safety Corrective Actions, or FSCAs, to reduce a risk of death or serious deterioration in the state of health associated with the use of amedical device that is already placed on the market. An incident is defined as any malfunction or deterioration in the characteristics and/or performance of adevice, as well as any inadequacy in the labeling or the instructions for use which, directly or indirectly, might lead to or might have led to the death of apatient or user or of other persons or to a serious deterioration in their state of health. An FSCA may include the recall, modification, exchange, destruction orretrofitting of the device. FSCAs must be communicated by the manufacturer or its European Authorized Representative to its customers and to the end usersof the device through Field Safety Notices. In September 2012, the European Commission adopted a proposal for a regulation which, if adopted, will changethe way that most medical devices are regulated in the EU, and may subject products to additional requirements. Pharmaceutical Coverage, Pricing and Reimbursement Significant uncertainty exists as to the coverage and reimbursement status of products approved by the FDA and other government authorities. Sales ofproducts will depend, in part, on the extent to which products are covered by third-party payors, including government health programs in the United Statessuch as Medicare and Medicaid, commercial health insurers and managed care organizations and the amount that will be paid. The process for determiningwhether a payor will provide coverage for a product may be separate from the process for setting the price or reimbursement rate that the payor will pay for theproduct once coverage is approved. Third-party payors may limit coverage to specific products on an approved list, or formulary, which might not include allof the approved products for a particular indication. Additionally, the containment of healthcare costs has become a priority of federal and state governments,and the prices of drugs have been a focus in this effort. The U.S. government, state legislatures and foreign governments have shown significant interest inimplementing cost-containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic products.Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures,could further limit our net revenue and results. In order to secure coverage and reimbursement for any product that might be approved for sale, a company may need to conduct expensivepharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costs required to obtainFDA or other comparable regulatory approvals. A payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate willbe approved. Third-party reimbursement may not be sufficient to maintain price levels high enough to realize an appropriate return on investment in productdevelopment. In the EU, pricing and reimbursement schemes vary widely from country to country. Some countries provide that drug products may be marketed onlyafter a reimbursement price has been agreed to. Some countries may require the completion of additional studies that compare the cost-effectiveness of aparticular product candidate to currently available therapies. For example, the EU provides options for its member states to restrict the range of drug productsfor which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. EU member statesmay approve a specific price for a drug product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing thedrug product on the market. Other member states allow companies to fix their own prices for drug products, but monitor and control company profits. Thedownward pressure on health care costs in general, particularly prescription drugs, has become intense. As a result, increasingly high barriers are beingerected to the entry of new products. In addition, in some countries, cross-border imports from low-priced markets exert competitive pressure that may reducepricing within a country. Any country that has price controls or reimbursement limitations for drug products may not allow favorable reimbursement andpricing arrangements. Healthcare Law and Regulation Healthcare providers, physicians and third-party payors play a primary role in the recommendation and prescription of drug products that are grantedmarketing approval. Arrangements with third-party payors and customers are subject to broadly applicable fraud and abuse and other healthcare laws andregulations. Such restrictions under applicable federal and state healthcare laws and regulations, include the following: 32· the federal Anti-Kickback Statute prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or providingremuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, order orrecommendation of, any good or service, for which payment may be made, in whole or in part, under a federal healthcare program such as Medicareand Medicaid; • the federal False Claims Act imposes civil penalties, and provides for civil whistleblower or qui tam actions, against individuals or entities forknowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a falsestatement to avoid, decrease or conceal an obligation to pay money to the federal government;• the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, imposes criminal and civil liability for executing a scheme todefraud any healthcare benefit program or making false statements relating to healthcare matters;• HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act and its implementing regulations, also imposesobligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiablehealth information;•the federal false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materiallyfalse statement in connection with the delivery of or payment for healthcare benefits, items or services;• the federal transparency requirements under the Patient Protection and Affordable Care Act, as amended by the Health Care and EducationReconciliation Act of 2010, or collectively the ACA will require applicable manufacturers of covered drugs, devices, drugs and medical supplies toreport to the Department of Health and Human Services information related to payments and other transfers of value to physicians and teachinghospitals and physician ownership and investment interests; and• analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or marketing arrangementsand claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers. Some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevantcompliance guidance promulgated by the federal government in addition to requiring drug manufacturers to report information related to payments tophysicians and other health care providers or marketing expenditures. State and foreign laws also govern the privacy and security of health information insome circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts. Sales and MarketingWe do not have a sales, marketing or distribution infrastructure and have limited experience in the sale, marketing and distribution ofpharmaceutical products. To achieve commercial success for any approved product, we must either develop a sales and marketing organization or outsourcethese functions to third parties. We expect to build a commercial infrastructure to allow us to market and sell certain of our product candidates whenapproved, if any, using a specialty sales force in the United States, and we may choose to establish commercialization capabilities in select countries outsidethe United States.Employees As of December 31, 2016, we had 20 full-time employees, of which 15 employees were engaged in research and development and five employeesprovided general and administrative support. Of our employees, ten have earned advanced degrees. Our employees are not represented by a labor union orcovered by a collective bargaining agreement.

Risk Factors The following risk factors and other information included in this Annual Report on Form 10-K should be carefully considered. The risks anduncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we presently deem lesssignificant may also impair our business operations. Please see page 2 of this Annual Report on Form 10-K for a discussion of some of the forward-lookingstatements that are qualified by these risk factors. If any of the following risks occur, our business, financial condition, results of operations and futuregrowth prospects could be materially and adversely affected. Risks Related to Our Financial Position and Need for Additional Capital We have incurred significant losses since inception. We expect to incur losses over the next several years and may never achieve or maintain profitability. Since inception, we have incurred significant operating losses. Our net loss was approximately $59.7 million, $46.5 million, and $23.8 million for theyears ended December 31, 2014, 2015 and 2016, respectively. We do not know whether or when we will become profitable. We have not generated anyrevenues to date from product sales. We have not completed development of any product candidate and have devoted substantially all of our financialresources and efforts to research and development, including pre-clinical studies and clinical trials. We expect to continue to incur significant expenses andoperating losses over the next several years. Our net losses may fluctuate significantly from quarter to quarter and year to year. Net losses and negative cashflows have had, and will continue to have, an adverse effect on our deficit and working capital. We anticipate that our expenses will increase substantially ifand as we:•continue our research and clinical development of our product candidates;• identify, develop and/or in-license additional product candidates;•seek regulatory approvals for any product candidates that successfully complete clinical trials;•in the future, establish a manufacturing, sales, marketing and distribution infrastructure;•maintain, expand and protect our intellectual property portfolio;•add equipment and physical infrastructure to support our research and development;•hire additional clinical, regulatory, quality control and scientific personnel; and• add operational, financial and management information systems and personnel, including personnel to support our product development and anyfuture commercialization efforts. To become and remain profitable, we must succeed in developing and eventually commercializing products that generate34significant revenue. We do not expect to generate significant revenue unless and until we are able to obtain marketing approval for, and successfullycommercialize, one or more of our product candidates. This will require us to be successful in a range of challenging activities, including completing pre-clinical studies and clinical trials of our product candidates, discovering additional product candidates, obtaining regulatory approval for our productcandidates, manufacturing, marketing and selling any products for which we may obtain regulatory approval, satisfying any post-marketing requirements andobtaining reimbursement for our products from private insurance or government payors. We are in the early stages of most of these activities and have not yetcommenced the other activities. We may never succeed in these activities and, even if we do, may never generate revenues that are significant enough toachieve profitability. Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timingor amount of increased expenses or when, or if, we will be able to achieve profitability. If we are required by the FDA or the EMA to perform trials in additionto those currently expected, or if there are any delays in completing our clinical trials or the development of any of our product candidates, our expensescould increase. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become andremain profitable would depress the value of our company and could impair our ability to raise capital, expand our business, maintain our research anddevelopment efforts, diversify our product offerings or even continue our operations. A decline in the value of our company could cause our stockholders tolose all or part of their investment in us. In addition, our recurring losses from operations, accumulated deficit and our need to raise additional financing in order to continue to fund ouroperations, may raise substantial doubt about our ability to continue as a going concern. Given our planned expenditures for the next several years,including, without limitation, expenditures in connection with our clinical trials, we and our independent registered public accounting firm may concludethat there is substantial doubt regarding our ability to continue as a going concern. Our very limited operating history may make it difficult for our stockholders to evaluate the success of our business to date and to assess our futureviability. We were formed as a wholly-owned subsidiary of Ikaria in October 2013 and became a stand-alone company in February 2014 following the Spin-Outand, as such, have a limited independent operating history. Our operations to date have been limited to organizing and staffing our company, developing and securing our technology, and undertaking pre-clinical studies and clinical trials of our product candidates. We have not yet demonstrated the ability to complete development of any product candidates,obtain marketing approvals, manufacture a commercial scale product, or arrange for a third party to do so on our behalf, or conduct sales and marketingactivities necessary for successful product commercialization. Consequently, any predictions our stockholders make about our future success or viability maynot be as accurate as they could be if we had a longer operating history or a history of successfully developing and commercializing products. Assuming we obtain marketing approval for any of our product candidates, we will need to transition from a company with a research and developmentfocus to a company capable of supporting commercial activities or we will need to enter into strategic partnerships. We may encounter unforeseen expenses,difficulties, complications and delays and may not be successful in such a transition. We will need substantial additional funding. If we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate our productdevelopment programs or commercialization efforts. We expect our expenses to increase in connection with our ongoing activities, particularly as we continue research and development and initiateadditional clinical trials of our product candidates and seek regulatory approval for these and potentially other product candidates. In addition, if we obtainregulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing,marketing, sales and distribution. In particular, the costs that may be required for the manufacture of any product candidate that receives marketing approvalmay be substantial. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raisecapital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or any futurecommercialization efforts. We plan to use our current cash and cash equivalents and marketable securities primarily to fund our ongoing research and development efforts. Wewill be required to expend significant funds in order to advance development of our product candidates and any other potential product candidates. Ourexisting cash and cash equivalents and marketable securities will not35be sufficient to fund all of the efforts that we plan to undertake or the completion of clinical development or commercialization of any of our productcandidates, such as the INOpulse for PAH Phase 3 program. Accordingly, we will be required to obtain further funding through public or private equityofferings, debt financings, collaborations or licensing arrangements or other sources. Adequate additional funding may not be available to us on acceptableterms or at all. Our failure to raise capital as and when needed would have a negative impact on our financial condition and our ability to pursue our businessstrategy. We believe that our existing cash and cash equivalents and marketable securities as of December 31, 2016, funds available under the At MarketIssuance Sales Agreement with FBR Capital Markets & Co. and MLV & Co. LLC, or ATM offering, and proceeds that we will become available to us uponsale of our state net operating losses and R&D tax credits under the State of New Jersey’s Technology Business Tax Certificate Transfer Program will besufficient to satisfy our operating cash needs for at least one year after the filing of this Annual Report on Form 10-K. We have based this estimate onassumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Our future capital requirements will dependon many factors, including:•the timing, progress, and results of our ongoing and planned clinical trials of our product candidates;•our ability to manufacture sufficient clinical supply of our products candidates and the costs thereof;•discussions with regulatory agencies regarding the design and conduct of our clinical trials and the costs, timing and outcome of regulatoryreview of our product candidates;•the cost and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of ourproduct candidates for which we receive marketing approval;•the costs of any other product candidates or technologies we pursue;•our ability to establish and maintain strategic partnerships, licensing or other arrangements and the financial terms of such agreements;•the revenue, if any, received from commercial sales of any product candidates for which we receive marketing approval; and•the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights anddefending any intellectual property-related claims. Identifying potential product candidates and conducting clinical trials is a time-consuming, expensive and uncertain process that takes years tocomplete, and we may never generate the necessary data or results required to obtain regulatory approval and achieve product sales. In addition, our productcandidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of products that we do not expectto be commercially available for several years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our businessobjectives. Adequate additional financing may not be available to us on acceptable terms, or at all. In addition, we may seek additional capital due tofavorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. See “CertainRelationships and Related Person Transactions—Corporate Conversion” for restrictions on issuing shares and incurring indebtedness that are part of ourStockholders Agreement.Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop andcommercialize our product candidates. Our ability to raise additional funds will depend, in part, on the success of our preclinical studies and clinical trialsand other product development activities, regulatory events, our ability to identify and enter into in-licensing or other strategic arrangements, and otherevents or conditions that may affect our value or prospects, as well as factors related to financial, economic and market conditions, many of which are beyondour control. We cannot be certain that sufficient funds will be available to us when required or on acceptable terms, if at all. Raising additional capitalthrough the sale of securities could cause significant dilution to our stockholders. If we are unable to secure additional funds on a timely basis or onacceptable terms, we may be required to defer, reduce or eliminate significant planned expenditures, restructure, curtail or eliminate some or all of ourdevelopment programs or other operations, dispose of technology or assets, pursue an acquisition of our company by a third party at a price that may result ina loss on investment for our stockholders, enter into arrangements that may require us to relinquish rights to certain of our product candidates, technologiesor potential markets, file for bankruptcy or cease operations altogether. Any of these events could have a material adverse effect on our business, financialcondition and results of operations. Moreover, if we are unable to obtain additional36funds on a timely basis, there will be substantial doubt about our ability to continue as a going concern and increased risk of insolvency and loss ofinvestment by our stockholders. Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to technologies or productcandidates. Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of public orprivate equity offerings, debt financings and/or license and development agreements with collaboration partners. To the extent that we raise additionalcapital through the sale of equity or convertible debt securities, the ownership interests of our stockholders may be materially diluted, and the terms of suchsecurities could include liquidation or other preferences or other rights such as anti-dilution rights that adversely affect the rights of our stockholders. Forexample, there could be potential dilution from the exercising of the warrants issued in connection with our secondary offering completed in November2016. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants that limit our ability to takespecified actions, such as incurring additional debt, making capital expenditures or declaring dividends. 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 ourproduct development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to developand market ourselves. If we raise funds through collaborations, strategic partnerships or marketing, distribution or licensing arrangements with third parties,we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms thatmay not be favorable to us. Risks Related to Our Business and Industry We face substantial competition from other pharmaceutical, biotechnology and medical device companies and our operating results may suffer if we failto compete effectively. The pharmaceutical, biotechnology and medical device industries are highly competitive. There are many pharmaceutical, biotechnology and medicaldevice companies, public and private universities and research organizations actively engaged in the research and development of products that may besimilar to our product candidates. In addition, other companies are increasingly looking at the cardiopulmonary disease market as a potential opportunity.Currently, there are 14 drugs approved for the treatment of PAH and there are also other potential therapies in clinical development, including other nitricoxide generation and delivery systems. Many of our competitors, either alone or through their strategic partners, have substantially greater name recognition and financial, technical,manufacturing, marketing and human resources than we do and significantly greater experience and infrastructure in the research and clinical development ofmedical products, obtaining FDA and other regulatory approvals of those products, and commercializing those products around the world. Additionalmergers and acquisitions in the pharmaceutical, biotechnology and medical device industries may result in even more resources being concentrated in ourcompetitors. Large pharmaceutical and medical device companies in particular have extensive expertise in pre-clinical and clinical testing and in obtainingregulatory approvals for medical products. In addition, academic institutions, government agencies and other public and private organizations conductingresearch may seek patent protection with respect to potentially competitive products or technologies. These organizations may also establish exclusivecollaborative or licensing relationships with our competitors. Accordingly, our competitors may be more successful than we may be in obtaining approval forinhaled nitric oxide products and achieving widespread market acceptance. We anticipate that we will face intense and increasing competition as newproducts and technologies become available. We will not be able to compete effectively unless we successfully:•design, develop and commercialize products that are competitive in the market;•attract qualified scientific, medical, sales and marketing, engineering and commercial personnel;•obtain patent and/or other proprietary protection for our processes and product candidates; and•obtain required regulatory approvals. 37It is also possible that Ikaria will seek to develop and commercialize inhaled nitric oxide products or product candidates in the Bellerophonindications. While a subsidiary of Ikaria has granted to us an exclusive license to develop and commercialize pulsed nitric oxide in the Bellerophonindications and the scope of that license includes certain technology developed or acquired by that subsidiary after the date of the license agreement, thelicense does not include technology developed or acquired by other subsidiaries or affiliates of Ikaria including Mallinckrodt's other subsidiaries. BecauseIkaria, Mallinckrodt and its other subsidiaries and affiliates are not subject to any non-competition obligations in our favor, it is possible that these othersubsidiaries or affiliates of Ikaria or Mallinckrodt may seek to develop or commercialize inhaled nitric oxide or other products or product candidates, usingtechnology not exclusively licensed to us that are competitive with our products or product candidates. Risks Related to the Discovery, Development and Commercialization of Our Product CandidatesWe are dependent on the success of our INOpulse product candidates and our ability to develop, obtain marketing approval for and successfullycommercialize these product candidates. If we are unable to develop, obtain marketing approval for or successfully commercialize our product candidates,either alone or through a collaboration, or experience significant delays in doing so, our business could be materially harmed. We currently have no products approved for sale and have invested a significant portion of our efforts and financial resources in the development ofour INOpulse for PAH, INOpulse for PH-COPD and Bioabsorbabable Cardiac Matrix, or BCM, product candidates. Our prospects are substantially dependenton our ability to develop, obtain marketing approval for and successfully commercialize these product candidates. In July 2015, we announced top-line results of our 303-patient, randomized, double-blind, placebo-controlled clinical trial of BCM, which showedno statistically significant treatment differences between patients treated with BCM and patients treated with placebo for both the primary and secondaryendpoints. Following these results, we are considering further exploratory work but we do not intend to proceed with further clinical development of BCM atthis point until and unless we can determine an alternative path forward. As a result, we have become even more dependent on the success of our INOpulseproduct candidates and our ability to develop, obtain marketing approval for and successfully commercialize our INOpulse product candidates. The success of our product candidates will depend on, among other things, our ability to successfully complete clinical trials of each productcandidate. The clinical trial process is uncertain, and failure of one or more clinical trials can occur at any stage of testing. For example, although we believeour Phase 2 clinical trials of INOpulse for PAH and INOpulse for PH-COPD support advancement into a Phase 3 clinical trial and further Phase 2 testing,respectively, the primary endpoints for both INOpulse for PAH and INOpulse for PH-COPD were not statistically significant for any of the doses tested. In addition to the successful completion of clinical trials, the success of our product candidates will also depend on several other factors, includingthe following: •receipt of marketing approvals from the FDA or other applicable regulatory authorities;•establishment of supply arrangements with third-party raw materials suppliers and manufacturers;•establishment of arrangements with third-party manufacturers to obtain finished drug products that are appropriately packaged for sale;•the performance of our future collaborators for one or more of our product candidates, if any;• the extent of any required post-marketing approval commitments to applicable regulatory authorities;•obtaining and maintaining patent, trade secret protection and regulatory exclusivity, both in the United States and internationally;•protection of our rights in our intellectual property portfolio;•launch of commercial sales if and when our product candidates are approved;•a continued acceptable safety profile of our product candidates following any marketing approval;38•commercial acceptance, if and when approved, by patients, the medical community and third-party payors;•establishing and maintaining pricing sufficient to realize a meaningful return on our investment; and•competition with other products. If we are unable to develop, obtain marketing approval for or successfully commercialize our INOpulse product candidates, either alone or through acollaboration, or experience significant delays in doing so, our business could be materially harmed. Clinical trials involve a lengthy and expensive process with an uncertain outcome. We may incur additional costs or experience delays in completing, orultimately be unable to complete, the development and commercialization of our product candidates. The risk of failure of all of our product candidates is high. It is impossible to predict when or if any of our product candidates will prove effective orsafe in humans or will receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate, wemust conduct extensive clinical trials to demonstrate the safety and efficacy of our product candidates in humans. Clinical testing is expensive, difficult todesign and implement, can take many years to complete and is uncertain as to outcome. A failure of one or more clinical trials can occur at any stage oftesting. The clinical development of our product candidates is susceptible to the risk of failure inherent at any stage of development, including failure todemonstrate efficacy in a clinical trial or across a broad population of patients, the occurrence of severe or medically or commercially unacceptable adverseevents, failure to comply with protocols or applicable regulatory requirements and determination by the FDA or any comparable non-U.S. regulatoryauthority that a drug product is not approvable. It is possible that even if one or more of our product candidates has a beneficial effect, that effect will not be detected during clinical evaluation as aresult of one or more of a variety of factors, including the size, duration, design, measurements, conduct or analysis of our clinical trials. Conversely, as aresult of the same factors, our clinical trials may indicate an apparent positive effect of a product candidate that is greater than the actual positive effect, ifany. Similarly, in our clinical trials we may fail to detect toxicity of or intolerability caused by our product candidates, or mistakenly believe that our productcandidates are toxic or not well tolerated when that is not in fact the case. Also, the exclusion criteria we define may not sufficiently rule out patients who areat a higher risk of being harmed by the treatment. For example, our exclusion criteria for pre-existing left heart dysfunction in our Phase 2 INOpulse clinicaltrials completed in 2014 may not rule out patients who may experience an adverse event related to left ventricular function due to exposure to nitric oxide. Inaddition, patients who are not excluded for reactive pulmonary vasculature when exposed to nitric oxide may still experience PH. The outcome of pre-clinical studies and early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinicaltrial do not necessarily predict final results, particularly when earlier trials are small, open-label or non-placebo-controlled trials and in trials that havedifferent endpoints than earlier trials. For example, for BCM, we were using the results of the 27-patient pilot trial conducted by BioLineRx Ltd. that usedanatomical changes to measure efficacy and did not have a control group as support for our larger ongoing clinical trial, which did not achieve the sameresults as the BioLineRx Ltd. trial. Many companies in the biotechnology, pharmaceutical and medical device industries have suffered significant setbacksin late-stage clinical trials after achieving positive results in earlier development, and we cannot be certain that we will not face such setbacks. The design of a clinical trial can determine whether its results will support approval of a product, and flaws in the design of a clinical trial may notbecome apparent until the clinical trial is well advanced or completed. We have limited experience in designing clinical trials and may be unable to designand execute a clinical trial to support marketing approval. In addition, pre-clinical and clinical data are often susceptible to varying interpretations andanalyses. Many companies that believed their product candidates performed satisfactorily in pre-clinical studies and clinical trials have nonetheless failed toobtain marketing approval for the product candidates. Even if we believe that the results of clinical trials for our product candidates warrant marketingapproval, the FDA or comparable non-U.S. regulatory authorities may disagree and may not grant marketing approval of our product candidates. In some instances, there can be significant variability in safety or efficacy results between different clinical trials of the same product candidate due tonumerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in andadherence to the clinical trial protocols and the rate of dropout among clinical trial participants. Any Phase 3 or other clinical trials that we may conduct maynot demonstrate the efficacy and safety necessary to obtain regulatory approval to market our product candidates. 39INOpulse is a sophisticated electro-mechanical device comprised of components that may fail or deteriorate over time or with improper use. If weexperience problems with, failure of, or delays in obtaining any INOpulse components, our business could be materially adversely harmed. Because INOpulse is a sophisticated electro-mechanical device, the parts which comprise the device are subject to sudden failure or to wear and tear,which may result in decreased function or failure of those parts over time. Although we perform scheduled, preventive maintenance on our drug deliverysystem to limit device failures, and additional maintenance as needed whenever a user reports a device malfunction, components of our devices may fail. Inaddition, although we have designed INOpulse to be simple and easy to use and will provide user manuals and other training materials, users of INOpulsemay use the devices improperly, which could cause the devices to fail or otherwise not work properly. There are several components in INOpulse that are custom designed or assembled for us. We are dependent on a single company to supply us withsome of these components. While we believe there are alternative suppliers from which we could purchase most of these components, there is a risk that asingle-source supplier could fail to deliver adequate supply, or could suffer a business interruption that could affect our supply of these components. We obtain some of the components for INOpulse through individual purchase orders executed on an as needed basis rather than pursuant to long-termsupply agreements. Our business, financial condition or results of operations could be adversely affected if any of our principal third-party suppliers ormanufacturers experience production problems, lack of capacity or transportation disruptions or otherwise cease producing such components. We intend to conduct, and may in the future conduct, clinical trials for certain of our product candidates at sites outside the United States, and the FDAmay not accept data from trials conducted in such locations. We have conducted, and may in the future choose to conduct, one or more of our clinical trials outside the United States. For example, our first of twoPhase 3 clinical trials of INOpulse for PAH will include sites outside of the United States, including Canada. Although the FDA may accept data from clinical trials conducted outside the United States, acceptance of this data is subject to certain conditionsimposed by the FDA. For example, the clinical trial must be well designed and conducted and performed by qualified investigators in accordance with GCPin the case of drug trials, or the Declaration of Helsinki or the laws and regulations of the country in which the research is conducted, whichever affordsgreater protection to the human subjects, in the case of device trials. The trial population must also adequately represent the U.S. population, and the datamust be applicable to the U.S. population and U.S. medical practice in ways that the FDA deems clinically meaningful. Generally, the patient population forany clinical trials conducted outside of the United States must be representative of the population for whom we intend to seek approval in the United States.In addition, while these clinical trials are subject to the applicable local laws, FDA acceptance of the data will be dependent upon its determination that thetrials also complied with all applicable U.S. laws and regulations. There can be no assurance that the FDA will accept data from trials conducted outside ofthe United States. If the FDA does not accept the data from our first of two Phase 3 clinical trials of INOpulse for PAH outside of the United States or anyfuture trial that we conduct outside the United States, it would likely result in the need for additional trials, which would be costly and time-consuming anddelay or permanently halt our development of INOpulse for PAH or any future product candidates. In addition, the conduct of clinical trials outside the United States could have a significant impact on us. Risks inherent in conducting internationalclinical trials include:•foreign regulatory requirements that could restrict or limit our ability to conduct our clinical trials;•administrative burdens of conducting clinical trials under multiple foreign regulatory schema;•foreign exchange fluctuations; and•diminished protection of intellectual property in some countries. If clinical trials of our product candidates fail to demonstrate safety and efficacy of our product candidates to the satisfaction of the FDA and comparablenon-U.S. regulators, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development andcommercialization of these product candidates. We are not permitted to commercialize, market, promote or sell any product candidate in the United States without40obtaining marketing approval from the FDA. Comparable non-U.S. regulatory authorities, such as the EMA, impose similar restrictions. We may never receivesuch approvals. We must complete extensive pre-clinical studies and clinical trials to demonstrate the safety and efficacy of our product candidates inhumans before we will be able to obtain these approvals. Any inability to successfully complete pre-clinical and clinical development could result in additional costs to us and impair our ability to generaterevenues from product sales. In addition, if (1) we are required to conduct additional clinical trials or other testing of our product candidates beyond the trialsand testing that we contemplate, (2) we are unable to successfully complete clinical trials of our product candidates or other testing, (3) the results of thesetrials or tests are unfavorable, uncertain or are only modestly favorable, such as in our Phase 2 clinical trials of INOpulse for PAH and INOpulse for PH-COPD,or (4) there are unacceptable safety concerns associated with our product candidates, we, in addition to incurring additional costs, 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 we intended or desired;•obtain approval with labeling that includes significant use or distribution restrictions or significant safety warnings, including boxed warnings;•be subject to additional post-marketing testing or other requirements; or•be required to remove the product from the market after obtaining marketing approval. If the FDA or other regulatory authority requires us to conduct additional testing or determines that an unacceptable amount of nitrogen dioxide isformed through the use of INOpulse, we may be required to alter the design of INOpulse, which may not be possible, and the clinical development timelinefor INOpulse may be delayed or prove to be more costly than we currently anticipate. If we experience any of a number of possible unforeseen events in connection with clinical trials of our product candidates, potential marketing approvalor commercialization of our product candidates could be delayed or prevented. We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent marketing approval of our productcandidates, including:•clinical trials of our product candidates may produce unfavorable or inconclusive results;• 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, patient enrollment in these clinicaltrials may be slower than we anticipate or participants may drop out of these clinical trials at a higher rate than we anticipate;•our third-party contractors, including those manufacturing our product candidates or components or ingredients thereof or conducting clinicaltrials on our behalf, 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 not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at aprospective trial site;•we may experience delays in reaching or fail to reach agreement on acceptable clinical trial contracts or clinical trial protocols with prospectivetrial sites;•patients who enroll in a clinical trial may misrepresent their eligibility to do so or may otherwise not comply with the clinical trial protocol,resulting in the need to withdraw such patients from the clinical trial, increase the needed enrollment size for the clinical trial or extend the clinicaltrial’s duration;41•regulators or institutional review boards may require that we or our investigators suspend or terminate clinical research for various reasons,including noncompliance with regulatory requirements or their respective standards of conduct, a finding that the participants are being exposed tounacceptable health risks, undesirable side effects or other unexpected characteristics of the product candidate or findings of undesirable effectscaused by a chemically or mechanistically similar drug or drug candidate;• the FDA or comparable non-U.S. regulatory authorities may disagree with our clinical trial design or our interpretation of data from pre-clinicalstudies and clinical trials;•the FDA or comparable non-U.S. regulatory authorities may find regulatory non-compliance with the manufacturing processes or facilities of third-party manufacturers with which we enter into agreements for clinical and commercial supplies;•the supply or quality of raw materials or manufactured product candidates or other materials necessary to conduct clinical trials of our productcandidates may be insufficient, inadequate or not available at an acceptable cost, or we may experience interruptions in supply; and• the approval policies or regulations of the FDA or comparable non-U.S. regulatory authorities may significantly change in a manner rendering ourclinical data insufficient to obtain marketing approval. Product development costs for us will increase if we experience delays in testing or pursuing marketing approvals and we may be required to obtainadditional funds to complete clinical trials and prepare for possible commercialization of our product candidates. We do not know whether any pre-clinicalstudies or clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. For example, although we completed aPhase 2 clinical trial for INOpulse for PH-COPD in 2014, we only began further Phase 2 development in this indication in 2016. Significant pre-clinical studyor clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow ourcompetitors to bring products to market before we do and impair our ability to successfully commercialize our product candidates and may harm our businessand results of operations. In addition, many of the factors that cause, or lead to, clinical trial delays may ultimately lead to the denial of marketing approval ofany of our product candidates. If we experience delays or difficulties in the enrollment of patients in clinical trials, we may not achieve our clinical development on our anticipatedtimeline, or at all, and our receipt of necessary regulatory approvals could be delayed or prevented. We may not be able to initiate or continue clinical trials for our INOpulse product candidates if we are unable to locate and enroll a sufficient numberof eligible patients to participate in clinical trials. Patient enrollment is a significant factor in the timing of clinical trials, and is affected by many factors,including:• the size and nature of the patient population;•the severity of the disease under investigation;•the proximity of patients to clinical sites;•the eligibility criteria for the trial;•the design of the clinical trial;•limitations placed on enrollment by regulatory authorities;• efforts to facilitate timely enrollment;•competing clinical trials; and•clinicians’ and patients’ perceptions as to the potential advantages and risks of the product candidate being studied in relation to other availabletherapies, including any new product candidates that may be approved for the indications we are investigating. 42For example, we may experience difficulty enrolling our clinical trials, including, but not limited to, any future clinical trials of INOpulse for PAH,which is an orphan disease due to the small number of patients who suffer from PAH, or any future clinical trials of INOpulse for PH-COPD because such trialsmay require that patients meet the restrictive enrollment criteria, such as having been diagnosed with both COPD and PH, be undergoing treatment withLTOT and not having significant left ventricular dysfunction. Our inability to enroll a sufficient number of patients for our clinical trials could result in significant delays or may require us to abandon one or moreclinical trials altogether. Enrollment delays in our clinical trials may result in increased development costs for our product candidates, delay or halt thedevelopment of and approval processes for our product candidates and jeopardize our ability to achieve our clinical development timeline and goals,including the dates by which we will commence, complete and receive results from clinical trials. Enrollment delays may also delay or jeopardize our abilityto commence sales and generate revenues from our product candidates. Any of the foregoing could cause the value of our company to decline and limit ourability to obtain additional financing, if needed.We may not obtain orphan drug exclusivity for any of our product candidates and indications, or we may not receive the full benefit of orphan drugexclusivity even if we obtain such exclusivity. Regulatory authorities in some jurisdictions, including the United States and EU, may designate drugs and biologics intended for the treatment ofrelatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug orbiologic intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals in the UnitedStates who have been diagnosed as having the disease or condition at the time of the submission of the request for orphan drug designation. The FDA hasgranted orphan drug designation to our nitric oxide program for the treatment of PAH. Accordingly, the first company to receive FDA approval for nitricoxide for the treatment of PAH will obtain seven years of marketing exclusivity, during which time the FDA may not approve another product containingnitric oxide as its active ingredient for the treatment of PAH, except under a limited of number of situations including a showing that another product isclinically superior. We have not yet applied for orphan drug designation in any jurisdictions outside of the United States. Even though we have obtained orphan drug designation for our nitric oxide program to treat PAH in the United States, and even if we obtain orphandrug designation for our product candidates in other indications, for our future product candidates or in other jurisdictions, due to the uncertaintiesassociated with developing pharmaceutical products, we may not be the first to obtain marketing approval for any particular orphan indication, or we maynot obtain approval for an indication for which we have obtained orphan drug designation. Further, even if we obtain orphan drug exclusivity for a productcandidate, that exclusivity may not protect the product effectively from competition because different drugs can be approved for the same condition. Forexample, even after an orphan drug is approved, the FDA can subsequently approve the same drug for the same condition if the FDA concludes that the laterdrug is safer, more effective or makes a major contribution to patient care. Orphan drug designation neither shortens the development time or regulatoryreview time of a drug, nor gives the drug any advantage in the regulatory review or approval process. Orphan drug exclusivity may be lost if the FDA, or theequivalent regulatory authority in jurisdictions outside of the United States, determines that the request for designation was materially defective or if themanufacturer is unable to assure sufficient quantity of the product to meet the needs of patients with the rare disease or condition. Serious adverse events, or SAEs, or undesirable side effects or other unexpected properties of our product candidates may be identified duringdevelopment that could delay or prevent the product candidate’s marketing approval. SAEs or undesirable side effects caused by, or other unexpected properties of, our product candidates could cause us, an institutional review board orregulatory authorities to interrupt, delay or halt clinical trials of one or more of our product candidates and could result in a more restrictive label or the delayor denial of marketing approval by the FDA or comparable non-U.S. regulatory authorities. If any of our product candidates is associated with SAEs orundesirable side effects or has properties that are unexpected, we may need to abandon development or limit development of that product candidate tocertain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. Many drugs or devices that initially showed promise in clinical or earlier stage testing have later been found to cause undesirable orunexpected side effects that prevented further development of the drug or device. For example, in our Phase 2 clinical trial for INOpulse for PAH completed in October 2014, SAEs were reported for four patients in the 25 mcg/kg idealbody weight/hour, or mcg, low-dose active treatment arm, including bacteremia, myelodysplastic syndrome, increased shortness of breath, and dyspnea, oneof which was assessed as possibly related to trial therapy. In the 75 mcg high-dose active treatment arm, nine patients had SAEs. The most common SAEsreported were syncope43and bronchitis/tracheobronchitis, one of which was assessed as possibly related to trial therapy. Discontinuation of trial therapy due to adverse eventsoccurred for two patients in the 75 mcg arm and one subject in the 25 mcg arm. Additional or more SAEs, undesirable side effects or other unexpectedproperties of INOpulse for PAH or our other product candidates could arise or become known during further clinical development. If such an event occursduring development, clinical trials for our product candidates could be suspended or terminated and the FDA or comparable foreign regulatory authoritiescould order us or our collaborators to cease further development, require us to conduct additional clinical trials or other tests or studies or deny approval ofthe applicable product candidate. Further, pending discussions with regulatory authorities, we may be required to conduct a drug-drug interaction study ofINOpulse for PH-COPD. We expect the FDA to require us primarily to study interactions with long-acting beta agonists, which is the only class of COPD drugthat has been identified as having potential adverse cardiac side effects, to confirm that pulsed inhaled nitric oxide does not increase systemic bio-availability of inhaled beta agonists. If the results of such a study indicate increased bioavailability that we are not able to address to the satisfaction of theFDA, marketing approval of INOpulse for PH-COPD, if any, may be limited to patients who do not use long-acting beta agonists. Additionally, INOpulse is an extension of the technology that is used in hospitals to deliver inhaled nitric oxide to neonates with a form of PH calledpersistent PH of the newborn. Persistent PH is an FDA-approved use of inhaled nitric oxide, which is currently marketed by Ikaria as INOmax. BecauseINOpulse draws on the established efficacy and safety of INOmax, if any SAEs or undesirable side effects or other unexpected properties of INOmax or otherinhaled nitric oxide delivery systems developed by Ikaria are identified, INOpulse may be adversely affected and we may be required to interrupt, delay orhalt our INOpulse clinical trials. We may not be successful in our efforts to identify or discover additional potential product candidates. A significant portion of the research that we are conducting involves the development of innovative approaches to the pulsed delivery of nitricoxide. Our drug-device discovery efforts may not be successful in creating drugs or devices that have commercial value or therapeutic utility. Our researchprograms may initially show promise in creating potential product candidates, yet fail to yield viable product candidates for clinical development for anumber of reasons, including that potential product candidates may, on further study, be shown to have harmful side effects or other characteristics thatindicate that they are unlikely to be product candidates that will receive marketing approval and achieve market acceptance. Our research programs to identify new product candidates will require substantial technical, financial and human resources. In addition, we mayfocus our efforts and resources on one or more potential product candidates that ultimately prove to be unsuccessful. Pursuant to the terms of our license agreement with Ikaria, we only have the right to develop and commercialize pulsed nitric oxide for theBellerophon indications; Ikaria retains the right to develop and commercialize inhaled nitric oxide products, including pulsed products, for all otherindications. Additionally, we are limited in the scope of potential product candidates that we can identify or discover due to non-competition agreementsthat we entered into with Ikaria, which agreements were amended in July 2015. In the event that we or one of our subsidiaries materially breach the provisionsof the non-competition agreements and do not cure such breach within 30 days after receiving written notice thereof from Ikaria, Ikaria will have the right toterminate the license agreement. If we are unable to identify suitable additional compounds for pre-clinical and clinical development, or at all, our ability to develop productcandidates and obtain product revenues in future periods could be compromised, which could result in significant harm to our financial position andadversely impact our stock price. If any of our product candidates receives marketing approval and we, or others, later discover that the product is less effective than previously believed orcauses undesirable side effects that were not previously identified, our ability to market the product could be compromised. Clinical trials of our product candidates are conducted in carefully defined subsets of patients who have agreed to enter into clinical trials.Consequently, it is possible that our clinical trials may indicate an apparent positive effect of a product candidate that is greater than the actual positiveeffect, if any, or alternatively fail to identify undesirable side effects. If, following approval of a product candidate, we, or others, discover that the drug is lesseffective than previously believed or causes undesirable side effects that were not previously identified, any of the following undesirable events could occur:•regulatory authorities may withdraw their approval of the product or seize the product;•we may be required to recall the product or change the way the product is administered;44• additional restrictions may be imposed on the marketing of, or the manufacturing processes for, the particular product;•we may be subject to fines, injunctions or the imposition of civil or criminal penalties;•regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication;•we may be required to create a handout, sometimes referred to as a Medication Guide, outlining the risks of the previously unidentified side effectsfor distribution to patients;•we could be sued and held liable for harm caused to patients; • the product may become less competitive; and•our reputation may suffer. Any of these events could have a material and adverse effect on our operations and business and could adversely impact our stock price. Even if one of our product candidates receives marketing approval, it 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, and the market opportunity for the product candidate may be smallerthan we estimate. We have never commercialized a product. Even if one of our product candidates is approved by the appropriate regulatory authorities for marketingand sale, it may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. Forexample, physicians are often reluctant to switch their patients from existing therapies even when new and potentially more effective or convenienttreatments enter the market. Further, patients often acclimate to the therapy that they are currently taking and do not want to switch unless their physiciansrecommend switching products or they are required to switch therapies due to lack of reimbursement for existing therapies. Efforts to educate the medical community and third-party payors on the benefits of our product candidates may require significant resources and maynot be successful. If any of our product candidates is approved but does not achieve an adequate level of market acceptance, we may not generate significantrevenues and we may not become profitable. The degree of market acceptance of, and potential market opportunity for, our product candidates, if approvedfor commercial sale, will depend on a number of factors, including:•the efficacy and safety of the product;•the potential advantages of the product compared to alternative treatments;•the prevalence and severity of any side effects;•the clinical indications for which the product is approved;•whether the product is designated under physician treatment guidelines as a first-line therapy or as a second- or third-line therapy;• limitations or warnings, including distribution or use restrictions, contained in the product’s approved labeling;•our ability to offer the product for sale at competitive prices;•our ability to establish and maintain pricing sufficient to realize a meaningful return on our investment;•our ability to prevent use of our INOpulse for PH-COPD device by PAH patients due to expected pricing differences;• the product’s convenience and ease of administration compared to alternative treatments;45•the willingness of the target patient population to try, and of physicians to prescribe, the product;•the strength of sales, marketing and distribution support;•the approval of other new products for the same indications;•changes in the standard of care for the targeted indications for the product;•the timing of market introduction of our approved products as well as competitive products and other therapies;•availability and amount of reimbursement from government payors, managed care plans, private health coverage insurers and other third-partypayors;•adverse publicity about the product or favorable publicity about competitive products; and•potential product liability claims. The potential market opportunities for our product candidates are difficult to estimate precisely. Our estimates of the potential market opportunities,including our estimates with respect to pricing and reimbursement, are predicated on many assumptions, including industry knowledge and publications,third-party research reports and other surveys. While we believe that our internal assumptions are reasonable, these assumptions involve the exercise ofsignificant judgment on the part of our management, are inherently uncertain and the reasonableness of these assumptions has not been assessed by anindependent source. If any of the assumptions proves to be inaccurate, the actual markets for our product candidates could be smaller than our estimates ofthe potential market opportunities. If we are unable to establish sales, marketing and distribution capabilities or enter into acceptable sales, marketing and distribution arrangements withthird parties, we may not be successful in commercializing any product candidates that we develop, if and when those product candidates are approved. We do not have a sales, marketing or distribution infrastructure and have limited experience in the sale, marketing and distribution of pharmaceuticalproducts. To achieve commercial success for any approved product, we must either develop a sales and marketing organization or outsource these functionsto third parties. We expect to build a commercial infrastructure to allow us to market and sell certain of our product candidates when approved, if any, using aspecialty sales force in the United States, and we may choose to establish commercialization capabilities in select countries outside the United States. Thedevelopment of sales, marketing and distribution capabilities will require substantial resources, will be time-consuming and could delay any product launch.We expect that we will commence the development of these capabilities prior to receiving approval of any of our product candidates. If the commerciallaunch of a product candidate for which we recruit a sales force and establish marketing and distribution capabilities is delayed or does not occur for anyreason, we could have prematurely or unnecessarily incurred these commercialization costs. Such a delay may be costly, and our investment could be lost ifwe cannot retain or reposition our sales and marketing personnel. In addition, we may not be able to hire or retain a sales force in the United States that issufficient in size or has adequate expertise in the medical markets that we plan to target. If we are unable to establish or retain a sales force and marketing anddistribution capabilities, our operating results may be adversely affected.If a potential partner has development or commercialization expertise or financial resources that we believe is particularly relevant to one of ourproduct candidates, then we may seek to collaborate with that potential partner even if we believe we could otherwise develop and commercialize theproduct independently. We may partner with third parties to commercialize our product candidates in certain countries outside the United States. As a resultof entering into arrangements with third parties to perform sales, marketing and distribution services, our product revenues or the profitability of theseproduct revenues may be lower, perhaps substantially lower, than if we were to directly market and sell products in those markets. Furthermore, we may beunsuccessful in entering into the necessary arrangements with third parties or may be unable to do so on terms that are favorable to us. In addition, we mayhave little or no control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our productcandidates effectively. If we do not establish sales and marketing capabilities, either on our own or in collaboration with third parties, we will not be successful incommercializing any of our product candidates that receive marketing approval. Even if we are able to commercialize any product candidate that we develop, the product may become subject to unfavorable pricing regulations, third-party payor reimbursement practices or healthcare reform initiatives that could harm our46business. The commercial success of our product candidates will depend substantially, both in the United States and abroad, on the extent to which the costs ofour product candidates will be paid by health maintenance, managed care, pharmacy benefit and similar healthcare management organizations, or reimbursedby government health administration authorities, private health coverage insurers and other third-party payors. If reimbursement is not available, or isavailable only to limited levels, we may not be able to successfully commercialize our product candidates. Even if coverage is provided, the approvedreimbursement amount may not be high enough to allow us to establish and maintain pricing sufficient to realize a meaningful return on our investment. There is significant uncertainty related to third-party payor coverage and reimbursement of newly approved drugs and devices. Marketing approvals,pricing and reimbursement for new drug and device products vary widely from country to country. Some countries require approval of the sale price of a drugor device before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In somenon-U.S. markets, pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketingapproval for a product in a particular country, but then be subject to price regulations that delay commercial launch of the product, possibly for lengthy timeperiods, which may negatively impact the revenues we are able to generate from the sale of the product in that country. Adverse pricing limitations mayhinder our ability to recoup our investment in one or more product candidates, even if our product candidates obtain marketing approval. Our ability to commercialize our product candidates will depend in part on the extent to which coverage and reimbursement for these products andrelated treatments will be available from government health administration authorities, private health insurers and other organizations. Governmentauthorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will cover andestablish reimbursement levels. The healthcare industry is acutely focused on cost containment, both in the United States and elsewhere. Governmentauthorities and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications, whichcould affect our ability to sell our product candidates profitably. These payors may not view our products, if any, as cost-effective, and coverage andreimbursement may not be available to our customers, or may not be sufficient to allow our products, if any, to be marketed on a competitive basis. Cost-control initiatives could cause us to decrease the price we might establish for products, which could result in lower than anticipated product revenues. If theprices for our products, if any, decrease or if governmental and other third-party payors do not provide adequate coverage or reimbursement, our prospects forrevenue and profitability will suffer. Approval of a product does not guarantee sufficient reimbursement to achieve commercial success. There may also be delays in obtaining coverage and reimbursement for newly approved products, and coverage may be more limited than theindications for which the product is approved by the FDA or comparable non-U.S. regulatory authorities. Moreover, eligibility for reimbursement does notimply that any product will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution.Reimbursement rates may vary, by way of example, according to the use of the product and the clinical setting in which it is used. Reimbursement rates mayalso be based on reimbursement levels already set for lower cost products or may be incorporated into existing payments for other services. In addition, increasingly, third-party payors are requiring higher levels of evidence of the benefits and clinical outcomes of new technologies and arechallenging the prices charged. We cannot be sure that coverage will be available for any product candidate that we commercialize and, if available, that thereimbursement rates will be adequate. Further, the net reimbursement for drug products may be subject to additional reductions if there are changes to lawsthat presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. An inability to promptly obtaincoverage and adequate payment rates from both government-funded and private payors for any our product candidates for which we obtain marketingapproval could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financialcondition.If the FDA or comparable non-U.S. regulatory authorities approve generic versions of any of our products that receive marketing approval, or suchauthorities do not grant our products appropriate periods of data exclusivity before approving generic versions of our products, the sales of our productscould be adversely affected. Once an NDA is approved, the product covered thereby becomes a “reference listed drug” in the FDA’s publication, “Approved Drug Products withTherapeutic Equivalence Evaluations.” Manufacturers may seek approval of generic versions of reference listed drugs through submission of ANDAs in theUnited States, or through a similar process in foreign jurisdictions. In support of an ANDA, a generic manufacturer need not conduct clinical studies. Rather,the applicant generally must show that its product has the same active ingredient(s), dosage form, strength, route of administration and conditions of use or47labeling as the reference listed drug and that the generic version is bioequivalent to the reference listed drug, meaning it is absorbed in the body at the samerate and to the same extent. Generic products may be significantly less costly to bring to market than the reference listed drug and companies that producegeneric products are generally able to offer them at lower prices. Thus, following the introduction of a generic drug, a significant percentage of the sales ofany branded product or reference listed drug may be typically lost to the generic product. The FDA may not approve an ANDA for a generic product until any applicable period of non-patent exclusivity for the reference listed drug hasexpired. Manufacturers may seek to launch these generic products following the expiration of the applicable marketing exclusivity period, even if we stillhave patent protection for our product. Competition that our products may face from generic versions of our products could materially and adversely impact our future revenue, profitabilityand cash flows and substantially limit our ability to obtain a return on the investments we have made in those product candidates. Product liability lawsuits against us could divert our resources, cause us to incur substantial liabilities and limit commercialization of any products thatwe may develop. We face an inherent risk of product liability claims as a result of the clinical testing of our product candidates despite obtaining appropriate informedconsents from our clinical trial participants. We will face an even greater risk if we commercially sell any product that we may develop. For example, we maybe sued if any product we develop allegedly causes injury or is found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale.Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product,negligence, strict liability or a breach of warranties. For example:•improper use or failure of INOpulse may result in rebound PH, which can be fatal in some patients;•rebound PH may also occur if both the primary and back-up devices fail before we can replace them, if the built-in back-up with a device does notwork properly or if the patient does not carry or have access to his or her back-up device; and• rebound PH can also occur in patients who were not previously considered at risk for this reaction and who may not have been provided anadequate back-up device.•Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, wemay incur substantial liabilities or be required to limit commercialization of our product candidates. Regardless of the merits or eventual outcome,liability claims may result in:•decreased demand for products that we may develop;•injury to our reputation and significant negative media attention;•withdrawal of clinical trial participants;•significant costs to defend resulting litigation;•substantial monetary awards 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. Although we maintain general liability insurance of $1.0 million in the aggregate, umbrella insurance in the amount of $10.0 million in the aggregateand clinical trial liability insurance of $20.0 million in the aggregate, this insurance may not fully cover potential liabilities that we may incur. The cost ofany product liability litigation or other proceeding, even if resolved in our favor, could be substantial. We will need to increase our insurance coverage if andwhen we begin the commercial sale of any product candidate that receives marketing approval. In addition, insurance coverage is becoming increasinglyexpensive. If we are unable to obtain or maintain sufficient insurance coverage at an acceptable cost or to otherwise protect against potential48product liability claims, it could prevent or inhibit the development and commercial production and sale of our product candidates, which could adverselyaffect our business, financial condition, results of operations and prospects. Our INOpulse devices use lithium-ion battery cells, which have been observed to catch fire or vent smoke and flame, and these events may raise concernsabout the batteries we use. The battery pack used in our INOpulse devices makes use of lithium-ion cells. On rare occasions, lithium-ion cells can rapidly release the energy theycontain by venting smoke and flames in a manner that can ignite nearby materials. Highly publicized incidents of laptop computers and cell phones burstinginto flames have focused consumer attention on the safety of these cells. There can be no assurance that the battery packs we use would not fail, which couldlead to property damage, personal injury or death, and may subject us to lawsuits. We may also have to recall our products, if any, which would be timeconsuming and expensive. Also, negative perceptions in the healthcare and patient communities regarding the suitability of lithium-ion cells for medicalapplications or any future incident involving lithium-ion cells could seriously harm our business, even in the absence of an incident involving us. Risks Related to Our Dependence on Third Parties The intellectual property underlying INOpulse is exclusively licensed from Ikaria. If Ikaria terminates the license agreement, or fails to prosecute,maintain or enforce the underlying patents, our business will be materially harmed. We have licensed the intellectual property underlying INOpulse from Ikaria. The license agreement prohibits us from sublicensing to any competitorof Ikaria any intellectual property licensed to us by Ikaria. In addition, we are required to ensure that all of our products candidates are used solely for thechronic treatment of the Bellerophon indications and to enter into written agreements with any customers that contain restrictions on the use of our productsand termination rights in the event such restrictions are violated. Ikaria has the initial right, but not the obligation, to prosecute and maintain all patents that are licensed to us pursuant to the license agreement. Whilewe have certain step-in rights to assume control if Ikaria declines to file, prosecute or maintain certain licensed patents that are core to our business, in theevent Ikaria reasonably determines that our actions could materially impair its business operations or intellectual property rights, Ikaria may prohibit us fromtaking such actions. In addition, Ikaria has the initial right, but not the obligation, to initiate a legal action against a third party with respect to any actual orsuspected infringement of patent rights licensed to us pursuant to the license agreement. We have the right to initiate legal action against a third-partyinfringer of licensed patents that are core to our business in the event Ikaria declines to take action with respect to such infringement, however, if Ikariadetermines that our pursuit of any such action could materially impair its business operations or intellectual property rights, Ikaria may prohibit us fromtaking any such action. The license agreement terminates, on an INOpulse product-by-INOpulse product basis, at such time as we are no longer actively and continuouslyengaged in the development or commercialization of such product. In addition, Ikaria may terminate the license agreement if, among other things, (1) webreach or fail to comply with any material term or condition required to be performed or complied with by us and do not cure such breach or failure within 30days after receiving written notice of such breach from Ikaria, (2) we or any of our affiliates breaches any of our agreements not to compete with Ikaria, (3) weor any of our affiliates challenges the validity or enforceability of the licensed patents or (4) we or any person that is a successor to our license rights marketsa generic nitric oxide product that is competitive with Ikaria’s INOmax product. Upon termination of the license agreement with respect to any INOpulseproduct candidate, we will lose our ability to market such INOpulse product candidate, and upon, Ikaria’s written request, be required to transfer any and allregulatory approvals relating to such INOpulse product candidate to Ikaria. We rely, and expect to continue to rely, on third parties to conduct our clinical trials, and those third parties may not perform satisfactorily, includingfailing to meet deadlines for the completion of such trials. We currently rely on third-party clinical research organizations, or CROs, to conduct our clinical trials. We expect to continue to rely on third parties,such as CROs, clinical data management organizations, medical institutions and clinical investigators, to conduct our clinical trials. Our agreements withthese third parties generally allow the third party to terminate the agreement at any time. If we are required to enter into alternative arrangements because ofany such termination, the introduction of our product candidates to market could be delayed. Our reliance on these third parties for research and development activities will reduce our control over these activities but will not relieve us of ourresponsibilities. For example, we design our clinical trials and will remain responsible for ensuring49that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA requires us tocomply with GCPs for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate andthat the rights, integrity and confidentiality of trial participants are protected. Our reliance on third parties that we do not control does not relieve us of theseresponsibilities and requirements. 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 time frames. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions. Furthermore, these third parties may also have relationships with other entities, some of which may be our competitors. If these third parties do notsuccessfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials in accordance with regulatory requirements or our statedprotocols, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates and will not be able to, or may bedelayed in our efforts to, successfully commercialize our product candidates. We also expect to rely on other third parties to store and distribute drug and device supplies for our clinical trials. Any performance failure on the partof our distributors could delay clinical development or marketing approval of our product candidates or commercialization of our products, producingadditional losses and depriving us of potential product revenue. We rely on Ikaria, as our single source supplier, for our supply of nitric oxide for the clinical trials of INOpulse. Ikaria’s inability to continuemanufacturing adequate supplies of nitric oxide, or its refusal to supply us with commercial quantities of nitric oxide on commercially reasonable terms,or at all, could result in a disruption in the supply of, or impair our ability to market, INOpulse. We have entered into a drug clinical supply agreement with Ikaria, pursuant to which Ikaria will manufacture and supply our requirements for nitricoxide for inhalation and corresponding placebo for use in clinical trials of INOpulse. Ikaria manufactures pharmaceutical-grade nitric oxide at its facility inPort Allen, Louisiana, which is the only FDA-inspected site for manufacturing medical nitric oxide in the world. Ikaria’s Port Allen facility is subject to therisks of a natural disaster or other business disruption. We maintain under controlled storage conditions a two- to three-month supply of clinical trial drugproduct, but there can be no assurance that we would be able to meet our requirements for INOpulse if there were a catastrophic event or failure of Ikaria’smanufacturing system. Because Ikaria’s Port Allen facility is the only FDA-inspected site that can manufacture nitric oxide for INOpulse and because themanufacture of a pharmaceutical gas requires specialized equipment and expertise, there are few, if any, third-party manufacturers to which we could contractthis work in a short period of time. Therefore, any disruption in Ikaria’s Port Allen facility, or the failure by Ikaria for any other reason to provide us withnitric oxide, could materially and adversely affect supplies of nitric oxide for INOpulse and our ongoing and planned clinical trials. Any such disruptionwould force us to seek nitric oxide from an alternative source, which may not be available on commercially reasonable terms, or at all. In addition, we do notcurrently have any arrangements with Ikaria to provide us with commercial quantities of nitric oxide. If we are unable to arrange for Ikaria to provide suchquantities on commercially reasonable terms, or at all, we may not be able to successfully produce and market INOpulse or may be delayed in doing so. We rely on third-party suppliers and manufacturers to produce and deliver clinical devices and supplies as well as for the servicing of these devices for ourINOpulse product candidates, and may also do so for other product candidates. Any failure by a third-party supplier or manufacturer to produce or deliversupplies for us or to provide necessary servicing may delay or impair our ability to complete our clinical trials or commercialize our product candidates. We currently rely, and expect to continue to rely, on third parties for supply of the device, cannula and certain other supplies for our INOpulse productcandidates. These suppliers are, and any future third-party suppliers with whom we enter into agreements may be, our sole suppliers of these devices or any ofour other current or future devices used in the INOpulse program. These suppliers are commonly referred to as single-source suppliers. If our suppliers fail todeliver materials and provide services needed for the production of the INOpulse device and related supplies or for our other product candidates in a timelyand sufficient manner, if they fail to comply with applicable regulations, or if we do not qualify alternate suppliers, clinical development or regulatoryapproval of our product candidates or commercialization of our products could be delayed, increasing our costs to complete clinical development and toobtain regulatory approval, which could deprive us of potential additional product revenue. If one or more of our product candidates are approved by the FDA or comparable regulatory authorities in other countries for commercial sale, we willneed to manufacture such product candidate in larger quantities. We do not currently have any arrangements with Ikaria or any other third-party manufacturerto provide commercial quantities of our product candidates. If we are unable to arrange for such a third-party manufacturing source, or fail to do so oncommercially reasonable terms, we may not be able to successfully produce and market our product candidates or may be delayed in doing so.50 Our product candidates currently in development are exclusively licensed from third parties, and we may enter into additional agreements to in-licensetechnology from third parties. If current or future licensors terminate the applicable license, or fail to maintain or enforce the underlying patents, ourcompetitive position and market share will be harmed. We have an exclusive worldwide license for our BCM product candidate, subject to certain retained rights of the licensor, from BioLine. Under theterms of the license agreement, we are obligated to use commercially reasonable efforts to develop and commercialize at least one product containing BCM.BioLine has the right to terminate its license agreement with us for an uncured material breach by us, upon which our exclusive license for BCM willterminate. We have also exclusively licensed INOpulse, for certain indications and settings, and subject to certain retained rights of the licensor, from Ikaria. We may enter into additional license agreements as part of the development of our business in the future. Such licensors, if any, may be responsible forprosecution of certain patent applications and maintenance of certain patents. Such licensors may not successfully prosecute such patent applications ormaintain such patents, which we have licensed and on which our business depends. Our licensors may fail to pursue litigation against third-party infringers,may fail to prove infringement, or may fail to defend against counterclaims of patent invalidity or unenforceability. If these in-licenses are terminated, or ifthe underlying patents fail to provide the intended market exclusivity, competitors would have the freedom to seek regulatory approval of, and to market,products identical to ours. This could have a material adverse effect on our competitive business position and our business prospects. Third parties may seek to hold us responsible for liabilities of Ikaria that we did not assume in our agreements. In connection with our separation from Ikaria, Ikaria has generally agreed to retain all liabilities that did not historically arise from our business. Thirdparties may seek to hold us responsible for Ikaria’s retained liabilities. Under our agreements with Ikaria, Ikaria has agreed to indemnify us for claims andlosses relating to these retained liabilities. However, if those liabilities are significant and we are ultimately liable for them, we cannot assure our stockholdersthat we will be able to recover the full amount of our losses from Ikaria. Any disputes that arise between us and Ikaria with respect to our past and ongoing relationships could harm our business operations. Disputes may arise between Ikaria and us in a number of areas relating to our past and ongoing relationships, including:•intellectual property, technology and business matters, including failure to make required technology transfers and failure to comply with non-compete provisions applicable to Ikaria and us;•labor, tax, employee benefit, indemnification and other matters arising from our separation from Ikaria;•distribution and supply obligations;•employee retention and recruiting;• business combinations involving us;•the nature, quality and pricing of transitional services Ikaria has agreed to provide us; and•business opportunities that may be attractive to both Ikaria and us. We may not be able to resolve any potential conflicts, and even if we do, the resolution may be less favorable than if we were dealing with anunaffiliated party. We may seek to enter into collaborations with third parties for the development and commercialization of our product candidates. If we fail to enter intosuch collaborations, or such collaborations are not successful, we may not be able to capitalize on the market potential of our product candidates. We may seek third-party collaborators for development and commercialization of our product candidates. Our likely collaborators for any marketing,distribution, development, licensing or broader collaboration arrangements include large and51mid-size pharmaceutical and medical device companies, regional and national biotechnology companies and pharmaceutical companies. We are notcurrently party to any such arrangement. However, if we do enter into any such arrangements with any third parties in the future, we will likely have limitedcontrol over the amount and timing of resources that our collaborators dedicate to the development or commercialization of our product candidates. Ourability to generate revenues from these arrangements will depend on our collaborators’ abilities to successfully perform the functions assigned to them inthese arrangements. Collaborations involving our product candidates would pose certain risks to us, including:•collaborators have significant discretion in determining the efforts and resources that they will apply to these collaborations;•collaborators may not pursue development and commercialization of our product candidates or may elect not to continue or renew development orcommercialization programs based on clinical trial results, changes in the collaborators’ strategic focus or available funding, or external factorssuch as an acquisition that diverts resources or creates competing priorities;• 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 products or productcandidates if the collaborators believe that competitive products are more likely to be successfully developed or can be commercialized underterms that are more economically attractive than ours;• collaborators with marketing and distribution rights to one or more of our products may not commit sufficient resources to the marketing anddistribution of such product or products;•collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way as to invitelitigation that could jeopardize or invalidate our 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;• disputes may arise between the collaborators and us that result in the delay or termination of the research, development or commercialization of ourproducts or product candidates or that result in costly litigation or arbitration that diverts management attention and resources; and•collaborations may be terminated and, if terminated, may result in a need for additional capital to pursue further development or commercializationof 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 acollaborator of ours were to be involved in a business combination, the continued pursuit and emphasis on our product development or commercializationprogram could be delayed, diminished or terminated. If we are not able to establish collaborations, we may have to alter our development and commercialization plans. Our drug and device development programs and the potential commercialization of our product candidates will require substantial additional cash tofund expenses. For some of our product candidates, we may decide to collaborate with biotechnology and pharmaceutical companies for the developmentand potential commercialization of those product candidates. We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend, amongother things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposedcollaborator’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 orsimilar regulatory authorities outside the United States, the potential market for the subject product candidate, the costs and complexities of manufacturingand delivering such product candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership oftechnology, which can exist if there is a challenge to such ownership without regard to the merits of the52challenge and industry and market conditions generally. The collaborator may also consider alternative product candidates or technologies for similarindications 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.The terms of our current or future license agreements may restrict our ability to enter into agreements on certain terms with future collaborators. For example,our license agreement with Ikaria prohibits us from granting a sublicense under any of the intellectual property licensed to us under such license agreement toany of our affiliates or any third party, in each case, that directly or indirectly competes with the Ikaria nitric oxide business, and any future licenseagreements may contain similar restrictions. Collaborations are complex and time-consuming to negotiate and document. In addition, there have been asignificant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential futurecollaborators. We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail thedevelopment of a product candidate, reduce or delay its development program or one or more of our other development programs, delay its potentialcommercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercializationactivities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need toobtain 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 furtherdevelop our product candidates or bring them to market and generate product revenue. Risks Related to Our Intellectual Property If we are unable to obtain and maintain patent protection for our technology and products or if the scope of the patent protection obtained is notsufficiently broad, our competitors could develop and commercialize technology and products similar or identical to ours, and our ability to successfullycommercialize our technology and products may be impaired. Our success depends in large part on our ability to obtain and maintain patent protection in the United States and other countries with respect to ourproprietary technology and products. We seek to protect our proprietary position by filing patent applications in the United States and abroad related to ourtechnologies and product candidates. The patents we have licensed from Ikaria relating to INOpulse’s feature of providing delivery of nitric oxide to ensure aconsistent dose over time expire as late as 2027 in the United States and as late as 2026 in certain other countries, as well as a patent with respect to the triple-lumen cannula that allows for safer and more accurate dosing of pulsed inhaled nitric oxide, which expires in 2033. The patent prosecution process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patentapplications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and developmentoutput before it is too late to obtain patent protection. Moreover, pursuant to our license agreement with Ikaria, we do not have the right to control thepreparation, filing and prosecution of patent applications, or to maintain the patents, covering the INOpulse technology that we license from Ikaria, except inthe event that Ikaria declines to prosecute or maintain certain licensed patents that are core to our business, elects to allow any of such patents to lapse orelects to abandon any such patents, in which case we would have step-in rights to assume control of the prosecution and/or maintenance of such patents,subject to Ikaria’s right to prohibit us from taking such actions if it reasonably determines that such actions could materially impair its business, operations orintellectual property rights. Similarly, under the terms of any future agreements that we may enter into with other third parties, we may not have the right tocontrol the preparation, filing and prosecution of patent applications, or to maintain the patents, covering the technology that is licensed to us under suchagreements. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions andhas in recent years been the subject of much litigation. In addition, the laws of non-U.S. countries may not protect our rights to the same extent as the laws ofthe United States. For example, European patent law restricts the patentability of methods of treatment of the human body more than U.S. law does.Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and otherjurisdictions are typically not published until 18 months after filing, and in some cases not at all. Therefore, we cannot know with certainty whether we werethe first to make the inventions claimed in our owned or licensed patents or pending patent applications, or that we or our licensors were the first to file forpatent protection of such inventions. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain.Our pending and future patent applications may not issue as patents that protect our technology or products, in whole or in part, or which effectively preventothers from commercializing competitive technologies and products. Changes in either the patent laws or interpretation of the patent laws in the UnitedStates and other countries may diminish the value of our patents or narrow the scope of our patent protection. 53Recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcementor defense of our owned or licensed issued patents. On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed intolaw. The Leahy-Smith Act includes a number of significant changes to U.S. patent law. The Leahy-Smith Act includes provisions that affect the way patentapplications are prosecuted and affect patent litigation. The USPTO recently developed new regulations and procedures to govern administration of theLeahy-Smith Act. Many of the substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first to file provisions, becameeffective on March 16, 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, theLeahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our owned or licensed patent applicationsand the enforcement or defense of our owned or licensed issued patents, all of which could have a material adverse effect on our business and financialcondition. Moreover, we may be subject to third-party preissuance submissions of prior art to the USPTO, or become involved in opposition, derivation,reexamination, inter partes review, post-grant review or interference proceedings challenging our owned or licensed patent rights or the patent rights ofothers. For example, Notices of Opposition to two European patents covering BCM that we licensed from BioLine have been filed with the European PatentOffice. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow thirdparties to commercialize our technology or products and compete directly with us, without payment to us, or result in our inability to manufacture orcommercialize products without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patentapplications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates. Even if our owned and licensed patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection,prevent competitors from competing with us, or otherwise provide us with any competitive advantage. Our competitors may be able to circumvent our ownedor licensed patents by developing similar or alternative technologies or products in a non-infringing manner. We may not receive patent term extensionunder the Hatch-Waxman Act that we expect or our rights during the extension period may be more limited than the full scope of the patent, making it easierfor our competitors to develop and market non-infringing technologies or products. The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our owned and licensed patents may bechallenged in courts or patent offices in the United States and abroad. Such challenges may result in loss of exclusivity or freedom to operate, or in patentclaims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializingsimilar or identical technology and products, or limit the duration of the patent protection of our technology and products. Given the amount of time requiredfor the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after suchcandidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others fromcommercializing products similar or identical to ours. We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming andunsuccessful. Competitors may infringe our owned or licensed patents or other intellectual property. To counter infringement or unauthorized use, we may berequired to file or participate in infringement claims, which can be expensive and time consuming. Any claims we or our licensors assert against perceivedinfringers could provoke these parties to assert counterclaims against us alleging that we infringe their patents. In addition, in a patent infringementproceeding, a court may decide that a patent of ours or our licensor is invalid or unenforceable, in whole or in part, construe the patent’s claims narrowly orrefuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result inany litigation proceeding could put one or more of our owned or licensed patents at risk of being invalidated or interpreted narrowly. Under the terms of our license agreement with Ikaria, in the event a third party is suspected of infringing any patent rights licensed to us byIkaria, Ikaria has the initial right, but not the obligation, to initiate a legal action against such third party. In the event that Ikaria declines to take any actionwith respect to an alleged infringement of certain licensed patents that are core to our business, we have the right, in certain circumstances, to initiate a legalaction against such third party, provided that, if Ikaria reasonably determines that our pursuit of any action with respect to infringement of any of such corepatents could materially impair Ikaria’s business operations or intellectual property rights, Ikaria may require us to not undertake or to cease any such action.Our inability to initiate a legal action against a third party suspected of infringing intellectual property rights important to our business may have a materialadverse effect on our competitive business position and our business prospects. If we fail to comply with our obligations under license agreements, we could lose rights that are important to our business.54 Under our license agreement with Ikaria, we have granted Ikaria a sole and exclusive worldwide license to any intellectual property rights that wecontrol for use in Ikaria’s nitric oxide business, are required to ensure that all of our products, if any, are used solely for the chronic treatment of Bellerophonindications and to enter into written agreements with any customers that contain restrictions on the use of our products and termination rights in the eventsuch restrictions are violated, and have agreed to pay 100% of the reasonable and documented costs incurred by Ikaria for the prosecution and maintenanceof certain licensed patents that are core to our business and 10% of such costs incurred by Ikaria for all other licensed patents. If we fail to comply with ourobligations under current or future license agreements, our counterparties may have the right to terminate these agreements, in which event we might not beable to develop, manufacture or market any product that is covered by the agreement or face other penalties under the agreement. Such an occurrence couldmaterially adversely affect the value of the product candidate being developed under any such agreement. We are also party to a license agreement withBioLine relating to our BCM product candidate that imposes, and we may enter into additional license agreements that may impose, various diligence,milestone payment, royalty and other obligations on us. Under our existing license agreement with BioLine, we are obligated to pay royalties on the net salesof product candidates or related technologies to the extent they are covered by the agreement. We also have diligence and development obligations underthis agreement.Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain andcould have a material adverse effect on the success of our business. Our commercial success depends upon our ability to develop, manufacture, market and sell our product candidates and use our proprietarytechnologies without infringing the proprietary rights of third parties. There is considerable intellectual property litigation in the pharmaceutical,biotechnology and medical device industries. We may become party to, or be threatened with, future adversarial proceedings or litigation regardingintellectual property rights with respect to our products and technology, including interference or derivation proceedings before the USPTO. Third partiesmay assert infringement claims against us based on existing patents or patents that may be granted in the future. 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 continuedeveloping and marketing our products and technology. However, we may not be able to obtain any required license on commercially reasonable terms or atall. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. Wecould be forced, including by court order, to cease commercializing the infringing technology or product. In addition, we could be found liable for monetarydamages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent. A finding of infringement could prevent us fromcommercializing our product candidates or force us to cease some of our business operations, which could materially harm our business. Claims that we havemisappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business. We may be subject to claims by third parties asserting that we or our employees have misappropriated their intellectual property, or claiming ownership ofwhat we regard as our own intellectual property. Many of our employees were previously employed at other pharmaceutical, biotechnology or medical device companies, including our competitors orpotential competitors. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, wemay be subject to claims that we or these employees have used or disclosed intellectual property, including trade secrets or other proprietary information, ofany such employee’s former employer. Litigation may be necessary to defend against these claims. In addition, while it is our policy to require our employees and contractors who may be involved in the development of intellectual property toexecute agreements assigning such intellectual property to us, we may be unsuccessful in timely obtaining such an agreement with each party who in factdevelops intellectual property that we regard as our own. Even if timely obtained, such agreements may be breached, and we may be forced to bring claimsagainst third parties, or defend claims they may bring against us, to determine the ownership of what we regard as our intellectual property. If we fail in prosecuting or defending any such claims, we may lose valuable intellectual property rights or personnel, in addition to paying monetarydamages. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs. Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities. Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to55incur significant expenses, and could distract our technical and management personnel from their normal responsibilities. In addition, there could be publicannouncements of the results of hearings, motions or other interim proceedings or developments, and if securities analysts or investors perceive these resultsto be negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase ouroperating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. We may not havesufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may be able to sustain the costs of suchlitigation or proceedings more effectively than we can because of their greater financial resources. Uncertainties resulting from the initiation andcontinuation of patent litigation or other proceedings could compromise our ability to compete in the marketplace. If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed. In addition to seeking patents for some of our technology and product candidates, we also rely on trade secrets, including unpatented know-how,technology and other proprietary information, to maintain our competitive position. We seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, outside scientific collaborators, contractmanufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention or patent assignment agreements with ouremployees and consultants. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including ourtrade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated atrade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. Even if we are successful in prosecuting such claims, any remedyawarded may be insufficient to fully compensate us for the improper disclosure or misappropriation. In addition, some courts inside and outside the UnitedStates are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by acompetitor, 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. Ifany of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be harmed. 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 maynot adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:•Others may be able to develop and commercialize treatments that are similar to our product candidates but that are not covered by the claims of thepatents that we own or have exclusively licensed.•We or our licensors might not have been the first to make the inventions covered by the issued patent or pending patent application that we own orhave exclusively licensed.•We or our licensors might not have been the first to file patent applications covering certain of our inventions.•Others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectualproperty rights.•It is possible that our pending patent applications will not lead to issued patents.•Issued patents that we own or have exclusively licensed may not provide us with any competitive advantages, or may be held invalid orunenforceable, as a result of legal challenges by our competitors.•Our competitors might conduct research and development activities in countries where we do not have patent rights and then use the informationlearned from such activities to develop competitive products for sale in our major commercial markets.•We may not develop additional proprietary technologies that are patentable.•The patents of others may have an adverse effect on our business.•Another party may be granted orphan drug exclusivity for an indication that we are seeking before us or may be granted orphan drug exclusivity forone of our products for another indication.56 Risks Related to Regulatory Approval of Our Product Candidates and Other Legal Compliance Matters Even if we complete the necessary clinical trials, the marketing approval process is expensive, time consuming and uncertain and may prevent us fromobtaining approvals for the commercialization of some or all of our product candidates. If we are not able to obtain, or if there are delays in obtaining,required regulatory approvals, we will not be able to commercialize our product candidates, and our ability to generate revenue will be materiallyimpaired. Our product candidates and the activities associated with their development and commercialization, including their design, testing, manufacture,safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale and distribution, are subject to comprehensive regulation by the FDAand other regulatory agencies in the United States and by the EMA and similar regulatory authorities outside the United States. Failure to obtain marketingapproval for a product candidate will prevent us from commercializing the product candidate. Our product candidates are in the early stages of developmentand are subject to the risks of failure inherent in drug and device development. We have not received approval to market any of our product candidates fromregulatory authorities in any jurisdiction. We have only limited experience in conducting and managing the clinical trials, and in filing and supporting theapplications necessary to gain marketing approvals and expect to rely on third-party CROs to assist us in this process. Securing marketing approval requiresthe submission of extensive pre-clinical and clinical data and supporting information to regulatory authorities for each therapeutic indication to establish theproduct candidate’s safety and efficacy. Securing marketing approval also requires the submission of information about the product manufacturing processto, and inspection of manufacturing facilities by, the regulatory authorities. Our product candidates may not be effective, may be only moderately effective ormay prove to have undesirable or unintended side effects, toxicities or other characteristics that may preclude our obtaining marketing approval or prevent orlimit commercial use. The process of obtaining marketing approvals, both in the United States and abroad, is expensive, may take many years if additional clinical trials arerequired, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the productcandidates involved. Changes in marketing approval policies during the development period, changes in or the enactment of additional statutes orregulations, or changes in regulatory review for each submitted product application, may cause delays in the approval or rejection of an application.Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data areinsufficient for approval and require additional pre-clinical, clinical or other studies. In addition, varying interpretations of the data obtained from pre-clinical and clinical testing could delay, limit or prevent marketing approval of a product candidate. Any marketing approval we ultimately obtain may belimited or subject to restrictions or post-approval commitments that render the approved product not commercially viable. If we experience delays inobtaining approval or if we fail to obtain approval of our product candidates, the commercial prospects for our product candidates may be harmed and ourability to generate revenues will be materially impaired. Even though we have obtained orphan drug designation from the FDA for the treatment of pulmonary arterial hypertension the designation-relatedmarketing exclusivity periods may be challenged by others or may prove to be of no practical benefit. In addition, even though we have reached agreementon a Special Protocol Assessment, or SPA, with the FDA with respect to our Phase 3 PAH program for INOpulse, the FDA is not obligated to approve INOpulsefor PAH as a result of the SPA if we fail to meet all the conditions of the SPA agreement or if safety or efficacy issues become evident after the trial begins.Therefore, we cannot provide assurance that positive results in the clinical trial will be sufficient for FDA approval.Our failure to obtain marketing approval in foreign jurisdictions would prevent our product candidates from being marketed abroad, and any approval weare granted for our product candidates in the United States would not assure approval of product candidates in foreign jurisdictions. In order to market and sell our products in the EU and many other jurisdictions, we must obtain separate marketing approvals and comply withnumerous and varying regulatory requirements. The approval procedure varies among countries and can involve additional testing. The time required toobtain approval may differ substantially from that required to obtain FDA approval. The regulatory approval process outside the United States generallyincludes all of the risks associated with obtaining FDA approval. In addition, in many countries outside the United States, it is required that the product beapproved for reimbursement before the product can be approved for sale in that country. We may not obtain approvals from regulatory authorities outside theUnited States on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, andapproval by one regulatory authority outside the United States does not ensure approval by regulatory authorities in other countries or jurisdictions or by theFDA. We may not be able to file for marketing approvals and may not receive necessary approvals to commercialize our products in any market. Even if we obtain marketing approval for our product candidates, the terms of approvals and ongoing regulation of our57products may limit how we manufacture and market our products and compliance with such requirements may involve substantial resources, which couldmaterially impair our ability to generate revenue. Even if marketing approval of a product candidate is granted, an approved product and its manufacturer and marketer are subject to ongoing reviewand extensive regulation, including the requirement to implement a risk evaluation and mitigation strategy or to conduct costly post-marketing studies orclinical trials and surveillance to monitor the safety or efficacy of the product. We must also comply with requirements concerning advertising and promotionfor any of our product candidates for which we obtain marketing approval. Promotional communications with respect to prescription drugs are subject to avariety of legal and regulatory restrictions and must be consistent with the information in the product’s approved labeling. Thus, we will not be able topromote any products we develop for indications or uses for which they are not approved. In addition, manufacturers of approved products and thosemanufacturers’ facilities are required to ensure that quality control and manufacturing procedures conform to cGMP, which include requirements relating toquality control and quality assurance as well as the corresponding maintenance of records and documentation and reporting requirements. We and ourcontract manufacturers could be subject to periodic unannounced inspections by the FDA and other regulatory authorities to monitor and ensure compliancewith cGMP. Accordingly, assuming we receive marketing approval for one or more of our product candidates, we and our contract manufacturers will continue toexpend time, money and effort in all areas of regulatory compliance, including manufacturing, production, product surveillance and quality control. If we arenot able to comply with post-approval regulatory requirements, we could have the marketing approvals for our products withdrawn by regulatory authoritiesand our ability to market any future products could be limited, which could adversely affect our ability to achieve or sustain profitability. Thus, the cost ofcompliance with post-approval regulations may have a negative effect on our operating results and financial condition. Any product candidate for which we obtain marketing approval will be subject to strict enforcement of post-marketing requirements and we could besubject to substantial penalties, including withdrawal of our product from the market, if we fail to comply with all regulatory requirements or if weexperience unanticipated problems with our products, when and if any of them are approved. Any product candidate for which we obtain marketing approval, along with the manufacturing processes, post-approval clinical data, labeling,advertising and promotional activities for such product, will be subject to continual requirements of and review by the FDA and other regulatory authorities.These requirements include, but are not limited to, restrictions governing promotion of an approved product, submissions of safety and other post-marketinginformation and reports, registration and listing requirements, cGMP requirements relating to manufacturing, quality control, quality assurance andcorresponding maintenance of records and documents, and requirements regarding the distribution of samples to physicians and recordkeeping. The FDA and other federal and state agencies, including the Department of Justice, closely regulate compliance with all requirements governingprescription drug and device products, including requirements pertaining to marketing and promotion of drugs and devices in accordance with the provisionsof the approved labeling and manufacturing of products in accordance with cGMP requirements. Violations of such requirements may lead to investigationsalleging violations of the Food, Drug, and Cosmetic Act and other statutes, including the False Claims Act and other federal and state health care fraud andabuse laws as well as state consumer protection laws. Our failure to comply with all regulatory requirements, and later discovery of previously unknownadverse events or other problems with our products, manufacturers or manufacturing processes, may yield various results, including:•litigation involving patients taking our products;•restrictions on such products, manufacturers or manufacturing processes;•restrictions on the labeling or marketing of a product;• restrictions on product distribution or use;•requirements to conduct post-marketing studies or clinical trials;•untitled or warning letters;• withdrawal of the products from the market;58•refusal to approve pending applications or supplements to approved applications that we submit;•recall of products;•fines, restitution or disgorgement of profits or revenues;•suspension or withdrawal of marketing approvals;•damage to relationships with any potential collaborators;•unfavorable press coverage and damage to our reputation;• refusal to permit the import or export of our products;•product seizure; or•injunctions or the imposition of civil or criminal penalties. Non-compliance by us or any future collaborator with regulatory requirements regarding safety monitoring or pharmacovigilance, and withrequirements related to the development of products for the pediatric population, can also result in significant financial penalties. Similarly, failure to complywith regulatory requirements regarding the protection of personal information could also lead to significant penalties and sanctions. Our relationships with customers and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws andregulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and futureearnings. Healthcare providers, physicians and third-party payors will play a primary role in the recommendation and prescription of any product candidates forwhich we obtain marketing approval. Our future arrangements with third-party payors and customers may expose us to broadly applicable fraud and abuseand other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market, sell anddistribute any products for which we obtain marketing approval. Restrictions under applicable federal and state healthcare laws and regulations, include thefollowing:•the federal Anti-Kickback Statute prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or providingremuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase,order or recommendation of, any good or service, for which payment may be made under a federal healthcare program such as Medicare andMedicaid;•the federal False Claims Act imposes criminal and civil penalties, including civil whistleblower or qui tam actions, against individuals or entitiesfor, among other things, knowingly presenting, or causing to be presented false or fraudulent claims for payment by a federal government program,or making a false statement or record material to payment of a false claim or avoiding, decreasing or concealing an obligation to pay money to thefederal government;•the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology forEconomic and Clinical Health Act, imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program and alsoimposes obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individuallyidentifiable health information;•the federal false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materiallyfalse statement in connection with the delivery of or payment for healthcare benefits, items or services;• the federal transparency requirements under the Patient Protection and Affordable Care Act, as amended by the Health Care and EducationReconciliation Act of 2010, or collectively the ACA, requires applicable manufacturers of covered drugs, devices, biologics and medical suppliesto report to the Department of Health and Human Services information related to payments and other transfers of value to physicians and teachinghospitals and physician ownership and investment interests; and59• analogous state laws and regulations such as state anti-kickback and false claims laws and analogous non-U.S. fraud and abuse laws andregulations, may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmentalthird-party payors, including private insurers, and some state laws require pharmaceutical companies to comply with the pharmaceutical industry’svoluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government in addition to requiring drugmanufacturers to report information related to payments to physicians and other health care providers or marketing expenditures. Some state lawsrequire pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant complianceguidance promulgated by the federal government and may require drug manufacturers to report information related to payments and other transfersof value to physicians and other healthcare providers or marketing expenditures. State and non-U.S. laws also govern the privacy and security ofhealth information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thuscomplicating compliance efforts. Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantialcosts. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or caselaw 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 anyother governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines,imprisonment, exclusion of products from government funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring ofour operations. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found to be not in compliance withapplicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. Laws and regulations governing any international operations we may have in the future may preclude us from developing, manufacturing and sellingcertain product candidates and products outside of the United States and require us to develop and implement costly compliance programs. If we expand our operations outside of the United States, we must dedicate additional resources to comply with numerous laws and regulations in eachjurisdiction in which we plan to operate. The Foreign Corrupt Practices Act, or the FCPA, prohibits any U.S. individual or business from paying, offering,authorizing payment or offering anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencingany act or decision of such third party in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates companieswhose securities are listed in the United States to comply with certain accounting provisions requiring the company to maintain books and records thataccurately and fairly reflect all transactions of the company, including international subsidiaries, and to devise and maintain an adequate system of internalaccounting controls for international operations. Compliance with the FCPA is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, the FCPApresents particular challenges in the medical device industry, because, in many countries, hospitals are operated by the government, and doctors and otherhospital employees are considered foreign officials. Certain payments to hospitals in connection with clinical trials and other work have been deemed to beimproper payments to government officials and have led to FCPA enforcement actions. Various laws, regulations and executive orders also restrict the use and dissemination outside of the United States, or the sharing with certain non-U.S.nationals, of information classified for national security purposes, as well as certain products and technical data relating to those products. If we expand ourpresence outside of the United States, it will require us to dedicate additional resources to comply with these laws, and these laws may preclude us fromdeveloping, manufacturing or selling certain product candidates and products outside of the United States, which could limit our growth potential andincrease our development costs. The failure to comply with laws governing international business practices may result in substantial civil and criminal penalties and suspension ordebarment from government contracting. The SEC also may suspend or bar issuers from trading securities on U.S. exchanges for violations of the FCPA’saccounting provisions. If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that couldharm our business. Currently, we do not operate any research and development or production facilities, including laboratory, development or manufacturing facilities.However, if we decided to operate our own research and development and production facilities, we60would be subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use,storage, treatment and disposal of hazardous materials and wastes. Such operations may involve the use of hazardous and flammable materials, includingchemicals and biological materials. Our operations may also produce hazardous waste products. Even if we contract with third parties for the disposal of thesematerials and wastes, we would not be able to eliminate the risk of contamination or injury from these materials. In the event of contamination or injuryresulting from our use or disposal of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. Wealso could incur significant costs associated with civil or criminal fines and penalties for failure to comply with such laws and regulations. Although we would increase our level of workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to ouremployees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not expect tomaintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our possible future storage or disposalof biological, hazardous or radioactive materials. In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. Thesecurrent or future laws and regulations may impair our research, development or production efforts. Our failure to comply with these laws and regulations alsomay result in substantial fines, penalties or other sanctions. Changes in law, including as a result of recent presidential administration changes, could have a negative impact on the approval of our drug candidates. We also cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action,either in the United States or abroad. For example, certain policies of the Trump administration may impact our business and industry. Namely, the Trumpadministration has taken several executive actions, including the issuance of a number of Executive Orders, that could impose significant burdens on, orotherwise materially delay, FDA’s ability to engage in routine regulatory and oversight activities such as implementing statutes through rulemaking,issuance of guidance, and review and approval of marketing applications. Notably, on January 23, 2017, President Trump ordered a hiring freeze for allexecutive departments and agencies, including the FDA, which prohibits the FDA from filling employee vacancies or creating new positions. Under the termsof the order, the freeze will remain in effect until implementation of a plan to be recommended by the Director for the Office of Management and Budget, orOMB, in consultation with the Director of the Office of Personnel Management, to reduce the size of the federal workforce through attrition. An under-staffedFDA could result in delays in FDA’s responsiveness or in its ability to review submissions or applications, issue regulations or guidance, or implement orenforce regulatory requirements in a timely fashion or at all. Moreover, on January 30, 2017, President Trump issued an Executive Order, applicable to allexecutive agencies, including the FDA, that requires that for each notice of proposed rulemaking or final regulation to be issued in fiscal year 2017, theagency shall identify at least two existing regulations to be repealed, unless prohibited by law. These requirements are referred to as the “two-for-one”provisions. This Executive Order includes a budget neutrality provision that requires the total incremental cost of all new regulations in the 2017 fiscal year,including repealed regulations, to be no greater than zero, except in limited circumstances. For fiscal years 2018 and beyond, the Executive Order requiresagencies to identify regulations to offset any incremental cost of a new regulation. In interim guidance issued by the Office of Information and RegulatoryAffairs within OMB on February 2, 2017, the administration indicates that the “two-for-one” provisions may apply not only to agency regulations, but also tosignificant agency guidance documents. It is difficult to predict how these requirement will be implemented, and the extent to which they will impact theFDA’s ability to exercise its regulatory authority. If these executive actions impose constraints on FDA’s ability to engage in oversight and implementationactivities in the normal course, our business may be negatively impacted.Risks Related to Employee Matters and Managing Growth Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel. We are dependent on the scientific, business development and clinical expertise of our management team. Leadership transitions can be inherentlydifficult to manage and may cause some disruptions in our business. Recruiting and retaining qualified scientific, clinical, manufacturing and sales and marketing personnel will also be critical to our success. Any of ouremployees may terminate their employment with us at any time. The loss of the services of our executive officers or other key employees could impede theachievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy.We do not maintain “key person” insurance for any of our executives or other employees. Furthermore, replacing executive officers and61key 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 ofskills and experience required to successfully develop, gain regulatory approval of and commercialize products. Competition to hire from this limited pool isintense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerouspharmaceutical, biotechnology and medical device companies for similar personnel. We also experience competition for the hiring of scientific and clinicalpersonnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist usin formulating our research and development and commercialization strategy. Our consultants and advisors may be employed by employers other than us andmay have commitments under consulting or advisory contracts with other entities that may limit their availability to us. Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements and insidertrading. We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include intentional failures to comply with FDAregulations, to provide accurate information to the FDA, to comply with federal and state healthcare fraud and abuse laws and regulations, to report financialinformation or data accurately, to disclose unauthorized activities to us or to comply with our code of business conduct and ethics. In particular, sales,marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, falseclaims, inappropriate promotion, 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. Employee misconduct could alsoinvolve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to ourreputation. The precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or inprotecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If anysuch actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impacton our business, including the imposition of significant fines or other sanctions. In addition, during the course of our operations, our directors, executives and employees may have access to material, non-public informationregarding our business, our results of operations or potential transactions we are considering. We may not be able to prevent a director, executive or employeefrom violating our insider trading policies and trading in our common stock on the basis of, or while having access to, material, non-public information. If adirector, executive or employee was to be investigated, or an action was to be brought against a director, executive or employee for insider trading, it couldhave a negative impact on our reputation and our stock price. Such a claim, with or without merit, could also result in substantial expenditures of time andmoney, and divert attention of our management team from other tasks important to the success of our business. Risks Related to Ownership of Our Common Stock Our principal stockholders have substantial control over us, which could limit ability of our stockholders to influence the outcome of key transactions,including any change of control. Our executive officers, directors and stockholders who are known by us to beneficially own more than 5% of our common stock, in the aggregate,beneficially owned a majority of our outstanding common stock as of March 2, 2017. As a result, if these stockholders were to choose to act together, theywould be able to exert a significant degree of influence over matters submitted to our stockholders for approval, as well as our management and affairs. Forexample, these persons, if they choose to act together, could delay, defer or prevent a change in control; entrench our management or board of directors; orimpede a merger, consolidation, takeover or other business combination involving us that other stockholders may desire. In addition, as of March 2, 2017, our largest stockholder, investment funds affiliated with New Mountain Capital, or the New Mountain Entities,beneficially owned, in the aggregate, approximately 43.1% of our outstanding common stock. Pursuant to the terms of a stockholders agreement, the NewMountain Entities are entitled to designate one director for nomination to our board of directors and to designate one director to the board of directors (orequivalent governing body) of each of our subsidiaries and to appoint the lead director of our board of directors, in each case, for so long as the NewMountain Entities or certain of their respective assignees beneficially own (i) 50% or more of the sum of (a) the aggregate number of shares of our commonstock that they collectively owned immediately prior to the closing of our IPO and (b) the number of shares of our common stock, if any, acquired followingthe closing of our IPO and (ii) 15% or more of our common stock outstanding (as set forth on the cover of our then most recently filed annual report onForm 10-K or quarterly report on Form 10-Q).62 The New Mountain Entities also have certain other rights conferred by the stockholders agreement. The New Mountain Entities may exert significantinfluence over matters requiring board approval. In addition, their consent is required for certain matters requiring approval by our stockholders, includingthe compensation and hiring and firing of our chief executive officer, business combinations, issuance of shares of our capital stock and incurrence of debt.These stockholder approval rights will terminate as outlined in “Certain Relationships and Related Person Transactions-Stockholders Agreements” in Part III-Item 13. Our second largest stockholder, Linde North America, Inc., an indirect wholly-owned subsidiary of Linde AG, or Linde, beneficially ownedapproximately 16.1% of our outstanding common stock, as of March 2, 2017. Pursuant to the terms of a stockholders agreement, Linde is entitled todesignate one director to our board of directors and to designate one director to the board of directors (or equivalent governing body) of each of oursubsidiaries if continuing ownership requirements are met as outlined in “Certain Relationships and Related Person Transactions-Stockholders Agreements”in Part III-Item 13. The New Mountain Entities and Linde may have interests that differ from the interests of our other stockholders, and they may vote in ways with whichour other stockholders disagree and that may be adverse to interests of our other stockholders. The concentration of ownership of our capital stock may havethe effect of delaying, preventing or deterring a change of control of our company, could deprive our stockholders of an opportunity to receive a premium fortheir common stock as part of a sale of our company and may adversely affect the market price of our common stock. A significant portion of our total outstanding shares are subject to volume limitations as to sale, but have registration rights that could allow them to besold into the market without such restrictions, which could cause the market price of our common stock to drop significantly, even if our business isperforming well. Sales of a substantial number of shares of our common stock in the public market could occur at any time, subject to certain restrictions describedbelow. These sales, or the perception in the market that holders of a large number of shares intend to sell shares, could reduce the market price of our commonstock. Certain holders of a significant number of shares of our common stock have rights, subject to certain conditions, to require us to file registrationstatements covering their shares or to include their shares in registration statements that we may file for ourselves or other stockholders. Many of these sharescould be freely sold without registration subject to the volume limitations applicable to affiliates under Rule 144. As of March 2, 2017, we had outstandingoptions to purchase an aggregate of 3,277,132 shares of our common stock, of which options to, purchase approximately 472,188 were vested andoutstanding and vested warrants to purchase an aggregate of 16,805,986 shares of our common stock. These shares can be freely sold in the public marketupon issuance, subject to volume limitations applicable to affiliates. If securities analysts do not publish research or reports about our business or if they publish negative evaluations of our stock, the price or trading volumeof our stock could decline. The trading market for our common stock relies, in part, on the research and reports that industry or financial analysts publish about us or our business.If no, or few, analysts commence coverage of us, the trading price of our stock would likely decrease. Even if we do obtain analyst coverage, if one or more ofthe analysts covering our business do not publish favorable reports or downgrade their evaluations of our stock, the price of our stock could decline. If one ormore analysts cease to cover our stock, we could lose visibility in the market for our stock, which in turn could cause our stock price or trading volume todecline. The price of our common stock may be volatile and fluctuate substantially, which could result in substantial losses for our stockholders. Our stock price may be volatile. The stock market in general, and the market for pharmaceutical companies in particular, has experienced extremevolatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors may not be able to selltheir shares of common stock at or above the price they paid for their shares. The market price for our common stock may be influenced by many factors,including:• actual or anticipated results from and any delays in our clinical trials, including our expected and ongoing clinical trials of our INOpulse productcandidates, as well as results of regulatory input on our clinical trial programs and regulatory reviews relating to the approval of our productcandidates;•the results of our efforts to discover, develop, acquire or in-license additional product candidates or products;•failure or discontinuation of any of our clinical development programs;63•the level of expenses related to any of our product candidates or clinical development programs;•commencement or termination of any collaboration or licensing arrangement;•disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for ourtechnologies;• announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures and capital commitments;•additions or departures of key scientific or management personnel;•variations in our financial results or those of companies that are perceived to be similar to us;• new products, product candidates or new uses for existing products introduced or announced by our competitors, and the timing of theseintroductions or announcements;•results of clinical trials of product candidates of our competitors;•general economic and market conditions and other factors that may be unrelated to our operating performance or the operating performance of ourcompetitors, including changes in market valuations of similar companies;•regulatory or legal developments in the United States and other countries;•changes in the structure of healthcare payment systems;•conditions or trends in the pharmaceutical, biotechnology and medical device industries;•actual or anticipated changes in earnings estimates, development time lines or recommendations by securities analysts;• announcement or expectation of additional financing efforts;•sales of common stock by us or our stockholders in the future, as well as the overall trading volume of our common stock; and•the other factors described in this “Risk Factors” section. If our quarterly operating results fall below the expectations of investors or securities analysts, the price of our common stock could declinesubstantially. Furthermore, any quarterly fluctuations in our operating results may, in turn, cause the price of our stock to fluctuate substantially. We believethat quarterly comparisons of our financial results are not necessarily meaningful and should not be relied upon as an indication of our future performance. In the past, following periods of volatility in the market price of a company’s securities, securities class-action litigation often has been instituted againstthat company. Such litigation, if instituted against us, could cause us to incur substantial costs to defend such claims and divert management’s attention andresources, which could seriously harm our business, financial condition, results of operations and prospects. An active trading market for our common stock may not be sustained. Our shares of common stock began trading on the NASDAQ Global Market on February 13, 2015. Given the limited trading history of our commonstock, there is a risk that an active trading market for our shares may not continue to develop or be sustained. If an active market for our common stock doesnot continue to develop or is not sustained, it may be difficult for investors to sell shares without depressing the market price for the shares, or at all.In January 2017, we received written notification from NASDAQ informing us that our stock had traded under $1.00 for thirty (30) consecutivetrading days, and that if it does not trade at or above $1.00 for ten (10) consecutive trading days during the next 180 days, our common stock would bedelisted absent meeting other conditions for delaying delisting. On64March 6, 2017, we received written notification from NASDAQ informing us that our stock had traded above $1.00 for ten consecutive trading days and weregained listing compliance. We have broad discretion in the use of our cash and cash equivalents and may not use them effectively. Our management has broad discretion in the application of our cash and cash equivalents and could spend these funds in ways that do not improve ourresults of operations or enhance the value of our common stock. The failure by our management to apply these funds effectively could result in financiallosses that could have a material adverse effect on our business, cause the price of our common stock to decline and delay the development of our productcandidates. Pending their use, we may invest our cash and cash equivalents in a manner that does not produce income or that loses value. We are an “emerging growth company,” and the reduced disclosure requirements applicable to emerging growth companies may make our common stockless attractive to investors. We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. We will remain an emerginggrowth company until the earlier of: (i) the last day of the fiscal year in which we have total annual gross revenues of $1 billion or more; (ii) December 31,2020; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we aredeemed to be a large accelerated filer under the rules of the SEC, which means the first day of the year following the first year in which the market value ofour common stock that is held by non-affiliates exceeds $700 million as of June 30. For so long as we remain an emerging growth company, we are permittedand intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies.These exemptions include:•not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002;•not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatoryaudit 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; and•exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any goldenparachute payments not previously approved. We may choose to take advantage of some, but not all, of the available exemptions. We have taken advantage of reduced reporting burdens in ourfilings with the SEC. In particular, we have not included all of the executive compensation information that would be required if we were not an emerginggrowth company. We cannot predict whether investors will find our common stock less attractive if we rely on certain or all of these exemptions. If someinvestors 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 morevolatile. In addition, the JOBS Act provides that an emerging growth company may take advantage of an extended transition period for complying with new orrevised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards wouldotherwise apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, we are subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. We are currently incurring and expect to continue to incur increased costs as a result of operating as a public company, and our management will berequired to devote substantial time to new compliance initiatives. We completed our IPO in February 2015. As a public company, we incur and expect to continue to incur significant legal, accounting and otherexpenses. We expect that our expenses will further increase after we are no longer an “emerging growth company.” We expect that we will need to hireadditional accounting, finance and other personnel to comply with the requirements of being a public company, and our management and other personnelwill need to devote a substantial amount of time towards maintaining compliance with these requirements. In addition, the Sarbanes-Oxley Act of 2002 andrules subsequently implemented by the SEC and NASDAQ have imposed various requirements on public companies, including establishment andmaintenance of effective disclosure and financial controls and corporate governance practices. Our management and other personnel will need to devote asubstantial amount of time to these compliance initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs andwill make some activities more time-65consuming and costly. For example, we expect that these rules and regulations may make it more difficult and more expensive for us to obtain director andofficer liability insurance. Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, we will be required to furnish a report by our management on our internalcontrol over financial reporting, including an attestation report on internal control over financial reporting issued by our independent registered publicaccounting firm. However, while we remain an emerging growth company, we will not be required to include an attestation report on internal control overfinancial reporting issued by our independent registered public accounting firm. Many of the internal controls over financial reporting have not been tested.To achieve compliance with Section 404 within the prescribed period, we will be engaged in a process to document and evaluate our internal control overfinancial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outsideconsultants and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improvecontrol processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting andimprovement process for internal control over financial reporting. Despite our efforts, there is a risk that neither we nor our independent registered publicaccounting firm will be able to conclude within the prescribed time frame that our internal control over financial reporting is effective as required bySection 404. This could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements. Our certificate of incorporation provides that the doctrine of “corporate opportunity” will not apply to any of our stockholders or directors, except inlimited circumstances, which may adversely affect our business or prospects. Our certificate of incorporation provides that the doctrine of “corporate opportunity” will not apply to any of our stockholders or directors, other thanany stockholder or director that is an employee of ours. The doctrine of corporate opportunity generally provides that a corporate fiduciary may not developan opportunity using corporate resources, acquire an interest adverse to that of the corporation or acquire property that is reasonably incident to the present orprospective business of the corporation or in which the corporation has a present or expectancy interest, unless that opportunity is first presented to thecorporation and the corporation chooses not to pursue that opportunity. The doctrine of corporate opportunity is intended to preclude officers or directorsfrom personally benefiting from opportunities that belong to the corporation. We have renounced any prospective corporate opportunity so that ourstockholders and directors (other than those that are employees of ours) and their respective representatives have no duty to communicate or presentcorporate opportunities to us, including any opportunity that becomes known to Ikaria and its directors, and have the right to either hold any corporateopportunity for its (and its representatives’) own account and benefit or to recommend, assign or otherwise transfer such corporate opportunity to personsother than us, including to Ikaria. As a result, our stockholders, directors and their respective affiliates will not be prohibited from investing in competingbusinesses or doing business with our customers. Therefore, we may be in competition with our stockholders, directors or their respective affiliates, and wemay not have knowledge of, or be able to pursue, a transaction that could potentially be beneficial to us. Accordingly, we may lose a corporate opportunityor suffer competitive harm, which could negatively impact our business or prospects. Our certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputesbetween 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 certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action orproceeding brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the DelawareGeneral Corporation Law, our certificate of incorporation or our bylaws, or any action asserting a claim against us that is governed by the internal affairsdoctrine. This provision 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. Alternatively, if a court were tofind this provision in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated withresolving such action in other jurisdictions, which could adversely affect our business and financial condition. Provisions in our certificate of incorporation, our bylaws or Delaware law might discourage, delay or prevent a change in control of our company orchanges in our management and, therefore, depress the trading price of our common stock. Provisions of our certificate of incorporation, our bylaws or Delaware law may discourage, delay or prevent a merger, acquisition or other change incontrol that stockholders may consider favorable, including transactions in which our stockholders might otherwise receive a premium for their shares. Theseprovisions may also prevent or frustrate attempts by our stockholders to change the composition of our board of directors or to replace or remove ourmanagement. These provisions66include:•limitations on the removal of directors;•a classified board of directors so that not all members of our board are elected at one time;•advance notice requirements for stockholder proposals and nominations;•limitations on the ability of stockholders to call and bring business before special meetings and to take action by written consent in lieu of ameeting;•limitations on the liability of, and the provision of indemnification to, our director and officers; and•the ability of our board of directors to authorize the issuance of blank check preferred stock, which could be issued with voting, liquidation,dividend and other rights superior to our common stock. In addition, we are subject to Section 203 of the Delaware General Corporation Law, which prohibits a publicly-held Delaware corporation fromengaging in a business combination with an interested stockholder, generally a person which together with its affiliates owns, or within the last three yearshas owned, 15% of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unlessthe business combination is approved in a prescribed manner. The existence of the foregoing provisions and anti-takeover measures could limit the price that investors might be willing to pay in the future forshares of our common stock. They could also deter potential acquirers of our company, thereby reducing the likelihood that investors could receive apremium for their shares of our common stock in an acquisition. Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation, if any, will be the sole sourceof gain for our stockholders. We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to finance thegrowth and development of our business. In addition, the terms of any future debt agreements may preclude us from paying dividends. As a result, capitalappreciation, if any, of our common stock will be the sole source of gain for our stockholders for the foreseeable future.Item 1B. Unresolved Staff CommentsNone.Item 2.

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 together with our financialstatements and related notes appearing elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis orset forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business and relatedfinancing, includes forward-looking statements that involve risks and uncertainties and should be read together with the “Risk Factors” section of thisAnnual Report on Form 10-K for a discussion of important factors that could cause actual results to differ materially from the results described in orimplied by the forward-looking statements contained in the following discussion and analysis. Overview Business We are a clinical-stage therapeutics company focused on developing innovative products at the intersection of drugs and devices that addresssignificant unmet medical needs in the treatment of cardiopulmonary diseases. Our focus is the continued development of our nitric oxide therapy forpatients with pulmonary hypertension, or PH, using our proprietary delivery system, INOpulse, with pulmonary arterial hypertension, or PAH, representingthe lead indication. Our INOpulse platform is based on our proprietary pulsatile nitric oxide delivery device.In February 2016, we announced positive data from the final analysis of our Phase 2 long-term extension clinical trial of INOpulse for PAH, whichwas Part 2 of our Phase 2 clinical trial of INOpulse for PAH. The data indicates a sustainability of benefit to PAH patients who received INOpulse therapy atthe 75 mcg/kg of ideal body weight/hour dose for an average of greater than 12 hours per day and were on long-term oxygen therapy, or LTOT. Afterreaching agreement with the FDA and the EMA on our Phase 3 protocol, we are moving forward with Phase 3 development. In September 2015, the FDAissued a SPA for our Phase 3 PAH program for INOpulse, which will include two confirmatory clinical trials. The first of the two Phase 3 trials, or INOvation-1,has been initiated with the first patient enrolled in June 2016. During January 2017, we received confirmation from the FDA of its acceptance of all of ourproposed modifications to our Phase 3 program. Under the newly modified Phase 3 program, the ongoing one-year INOvation-1 study, and a secondconfirmatory randomized withdrawal study with approximately 40 patients who will be crossing over from the INOvation-1 study, can serve as the twoadequate and well-controlled studies to support a NDA filing for INOpulse in PAH subjects on LTOT. Both studies include an interim analysis approximatelyhalf-way through each study to assess for efficacy and futility. The interim analysis for the INOvation-1 study also includes a potential sample sizereassessment.We completed a randomized, placebo-controlled, double-blind, dose-confirmation Phase 2 clinical trial of INOpulse for PH-COPD in July 2014. Wereceived results from this trial, and we have initiated further Phase 2 testing to demonstrate the potential benefit on exercise capacity. In September 2015, anoral presentation of late-breaking data from a clinical trial sponsored by us was presented at the European Respiratory Society International Congress 2015 inAmsterdam. The data showed that INOpulse improved vasodilation in patients with PH-COPD. In July 2016, the results were published in the InternationalJournal of COPD in an article titled "Pulmonary vascular effects of pulsed inhaled nitric oxide in COPD patients with pulmonary hypertension". Buildingupon this and other work we have done over recent quarters, we have initiated Phase 2 testing for the use of the INOpulse device for PH-COPD patients toevaluate the potential benefit of chronic use on exercise capacity, with the first patient enrolled in October 2016.We have begun clinical testing of the INOpulse therapy to treat PH associated with idiopathic pulmonary fibrosis, or PH-IPF, based on feedback fromthe medical community and the large unmet medical need for this condition. Our first patient was enrolled in our Phase 2 study in the second quarter of 2016.In addition, other opportunities for the application of our INOpulse platform include the following indications: chronic thromboembolic PH, or CTEPH, PHassociated with sarcoidosis and PH associated with pulmonary edema from high altitude sickness.We have devoted all of our resources to our therapeutic discovery and development efforts, including conducting clinical trials for our productcandidates, protecting our intellectual property and the general and administrative support of these operations. We have devoted significant time andresources to developing and optimizing our drug delivery system, INOpulse, which operates through the administration of nitric oxide as brief, controlledpulses that are timed to occur at the beginning of a breath. In addition, in prior years, we had incurred significant costs to scale up manufacturing of BCM tosupport our clinical trials.To date, we have generated no revenue from product sales. We expect that it will be several years before we commercialize a product candidate, ifever.70 Financial Operations OverviewPrior to February 2014, we were a wholly-owned subsidiary of Ikaria, Inc. (a subsidiary of Mallinckrodt plc), or Ikaria. As part of an internalreorganization of Ikaria in October 2013, Ikaria transferred to us exclusive worldwide rights, with no royalty obligations, to develop and commercializepulsed nitric oxide in PAH, PH-COPD and PH-IPF. In November 2015, we entered into an amendment to our exclusive cross-license, technology transfer andregulatory matters agreement with Ikaria that included a royalty equal to 3% of net sales of any commercial products for PAH. Following the internalreorganization, in February 2014, Ikaria distributed all of our then outstanding units to its stockholders through the payment of a special dividend on a prorata basis based on each stockholder’s ownership of Ikaria capital stock, which we refer to as the Spin-Out, and as a result we became a stand-alone company. Revenue To date, we have not generated any revenue from product sales and may not generate any revenue from product sales for the next several years, if ever.In the future, we may generate revenue from a combination of product sales, license fees and milestone payments in connection with strategic partnerships,and royalties from the sale of products developed under licenses of our intellectual property. Our ability to generate revenue and become profitable dependsprimarily on our ability to successfully develop and commercialize or partner our product candidates as well as any product candidates we may advance inthe future. We expect that any revenue we may generate will fluctuate from quarter to quarter as a result of the timing and amount of any payments we mayreceive under future partnerships, if any, and from sales of any products we successfully develop and commercialize, if any. If we fail to complete thedevelopment of any of our product candidates currently in clinical development or any future product candidates in a timely manner, or to obtain regulatoryapproval for such product candidates, our ability to generate future revenue, and our business, results of operations, financial condition and cash flows andfuture prospects would be materially adversely affected. Research and Development Expenses Research and development expenses consist of costs incurred in connection with the development of our product candidates, including upfront anddevelopment milestone payments, related to in-licensed product candidates and technologies. In order to fairly present our historical information for periods prior to the Spin-Out, certain departmental expenses from Ikaria have been allocated tous. The allocations were applied to us for the purpose of presenting our company as a stand-alone entity. Direct and indirect costs for periods prior to theSpin-Out related to the INOpulse and Bioabsorbabable Cardiac Matrix, or BCM, clinical programs have been allocated to us. All allocations were based onactual costs incurred. For purposes of allocating non-project specific expenses, each Ikaria department head provided information as to the percentage ofemployee time incurred on our behalf. Research and development expenses primarily consist of: •employee-related expenses, including salary, benefits and stock-based compensation expense;•expenses incurred under agreements with contract research organizations, investigative sites that conduct our clinical trials and consultants thatconduct a portion of our pre-clinical studies; •expenses relating to vendors in connection with research and development activities;•the cost of acquiring and manufacturing clinical trial materials;•facilities, depreciation of fixed assets and allocated expenses;•lab supplies, reagents, active pharmaceutical ingredients and other direct and indirect costs in support of our pre-clinical and clinical activities;•device development and drug manufacturing engineering;•license fees related to in-licensed products and technology; and•costs associated with non-clinical activities and regulatory approvals.71 We expense research and development costs as incurred. Conducting a significant amount of research and development is central to our business model. Product candidates in late stages of clinicaldevelopment generally have higher development costs than those in earlier stages of clinical development primarily due to the increased size and duration oflate-stage clinical trials. Subject to the availability of requisite financing, we plan to increase our research and development expenses for ongoing clinicalprograms for the foreseeable future as we seek to continue multiple clinical trials for our product candidates, including to potentially advance INOpulse forPH-IPF, and seek to identify additional early-stage product candidates. We track external research and development expenses and personnel expenses on a program-by-program basis. We use our employee andinfrastructure resources, including regulatory, quality, clinical development and clinical operations, across our clinical development programs and haveincluded these expenses in research and development infrastructure. Research and development laboratory expenses are also not allocated to a specificprogram and are included in research and development infrastructure. Engineering activities related to INOpulse and the manufacture of cylinders related toINOpulse are included in INOpulse engineering. INOpulse for PAH We completed a randomized, placebo-controlled, double-blind Phase 2 clinical trial of INOpulse for PAH in October 2014. The goal of the trial was todetermine the safety, tolerability and efficacy of two different doses of INOpulse for PAH. In February 2016, we performed the final analysis of our Phase 2long-term extension clinical trial of INOpulse for PAH, which is Part 2 of our Phase 2 clinical trial of INOpulse for PAH, which reinforced the results fromPart 1 of our Phase 2 clinical trial of INOpulse for PAH. After reaching agreement with the FDA and the EMA on our Phase 3 protocol, we moved forward withPhase 3 development with the first patient enrolled in June 2016. INOpulse for PH-COPD We completed a randomized, placebo-controlled, double-blind, dose-confirmation Phase 2 clinical trial of INOpulse for PH-COPD in July 2014. Wereceived results from this trial, and we have initiated Phase 2 testing for the use of the INOpulse device for PH-COPD patients to evaluate the potential benefitof chronic use on exercise capacity, with the first patient enrolled in October 2016.INOpulse for PH-IPFWe initiated our Phase 2 studies in PH-IPF in 2016 consisting of an exploratory acute hemodynamic study followed by exercise capacity. Our firstpatient was enrolled in our Phase 2 study in the second quarter of 2016. BCM In December 2011, we initiated a clinical trial of BCM, which we refer to as our PRESERVATION I trial, in December 2011, and completed enrollmentin December 2014. Top-line results from the randomized, double-blind, placebo-controlled clinical trial were announced in July 2015. Following the results,we are considering further exploratory work but we do not intend to proceed with further clinical development of BCM at this point until and unless we candetermine an alternative path forward. Research and Development Infrastructure We invest in regulatory, quality, clinical development and clinical operations activities, which are expensed as incurred. These activities primarilysupport our clinical development programs. INOpulse Engineering We have invested a significant amount of funds in INOpulse, which is configured to be highly portable and compatible with available modes of LTOTvia nasal cannula delivery. Our Phase 2 clinical trials of INOpulse for PAH and INOpulse for PH-COPD utilized the first generation INOpulse DS device. Webelieve our second generation INOpulse device, as well as a custom triple-lumen cannula, will significantly improve several characteristics of our INOpulsedelivery system. We have also invested in design and engineering technology, through Ikaria, for the manufacture of our drug cartridges. In February 2015,we entered into an agreement with Flextronics Medical Sales and Marketing Ltd., a subsidiary of Flextronics International Ltd., or72Flextronics, to manufacture and service the INOpulse devices that we are using in our ongoing clinical trials of INOpulse for PAH and INOpulse for PH-COPDand PH-IPF. It is difficult to determine with certainty the duration and completion costs of our current or any future pre-clinical programs and any of our current orfuture clinical trials and any future product candidates we may advance, or if, when or to what extent we will generate revenue from the commercializationand sale of any of our product candidates that obtain regulatory approval. We may never succeed in achieving regulatory approval for any of our productcandidates. The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including theuncertainties of any future clinical trials and pre-clinical studies, uncertainties in clinical trial enrollment rate and significant and changing governmentregulation. In addition, the probability of success for each product candidate will depend on numerous factors, including competition, manufacturingcapability and commercial viability. A change in the outcome of any of these variables with respect to the development of a product candidate could changesignificantly the costs and timing associated with the development of that product candidate. For example, if the FDA or other regulatory authority were torequire us to conduct clinical trials beyond those that we currently anticipate will be required for the completion of clinical development of a productcandidate, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financialresources and time with respect to the development of that product candidate. We will determine which programs to pursue and how much to fund eachprogram in response to the scientific and clinical success of each product candidate, as well as an assessment of each product candidate’s commercialpotential, including the likelihood of regulatory approval on a timely basis. General and Administrative Expenses General and administrative expenses include salaries and costs related to executive, finance, and administrative support functions, patent filing, patentprosecution, professional fees for legal, insurance, consulting, investor relations, human resources, information technology and auditing and tax services nototherwise included in research and development expenses.

Total operating expenses for the year ended December 31, 2016 were $23.8 million compared to $48.2 million for the yearended December 31, 2015, a decrease of $24.5 million, or 51%. This decrease was primarily due to reduced general and administrative expenses, reductionsin research and development expenses pertaining to our development of BCM, reduced research and development infrastructure expenses, and reducedINOpulse engineering expenses. Research and Development Expenses. Total research and development expenses for the year ended December 31, 2016 were $16.7 million comparedto $33.4 million for the year ended December 31, 2015, a decrease of $16.7 million, or 50%. Total research and development expenses consisted primarily ofthe following:· BCM research and development expenses for the year ended December 31, 2016 were $0.4 million compared to $8.2 million for the year endedDecember 31, 2015, a decrease of $7.7 million, or 95%. The decrease was primarily due to us suspending further clinical development of BCMfollowing the PRESERVATION I results in July 2015.· PAH research and development expenses for the year ended December 31, 2016 were $9.4 million compared to $10.7 million for the year endedDecember 31, 2015, a decrease of $1.2 million, or 12%. The decrease was primarily due to the completion of the Phase 2 clinical trial in late-2014and a reversal of an accrual in the year ended December 31, 2015 partially offset by increased costs in anticipation of the start of the Phase 3clinical trials.· Research and development infrastructure expenses for the year ended December 31, 2016 were $4.7 million compared to $8.6 million for the yearended December 31, 2015, a decrease of $3.8 million, or 45%. The decrease was due to reduced expenses payable to Ikaria as a result of thetermination of the TSA effective September 30, 2015 and reduced personnel costs as a result of the restructuring that occurred in the second half of2015. · INOpulse engineering expenses for the year ended December 31, 2016 were $1.9 million compared to $6.0 million for the year ended December 31,2015, a decrease of $4.1 million, or 69%. The decrease was driven by reduced expenses payable to Ikaria as a result of the termination of the TSA,reduced development costs for the INOpulse device and triple-lumen cannula and reduced personnel costs as a result of the restructuring thatoccurred in the second half of 2015. General and Administrative Expenses.

Other Operating Income. We had no other operating income for the year ended December 31, 2016 compared to $1.7 million for the year endedDecember 31, 2015 related to the 2015 Services Agreement with Ikaria.Change in fair value of common stock warrant liability. Change in fair value of common stock warrant liability for the year ended December 31,2016 was $0.6 million and we had no change in fair value of common stock warrant liability for the year ended December 31, 2015 as the warrants wereissued in November 2016.Income Tax Benefit. We had $(0.4) million of income tax benefit for the year ended December 31, 2016 related to the sale of research anddevelopment tax credits in November 2016. There was no income tax benefit for the year ended December 31, 2015.Comparison of Years Ended December 31, 2015 and 2014 The following table summarizes our results of operations for the years ended December 31, 2015 and 2014, together with the changes in these items indollars and as a percentage.

Total operating expenses for the year ended December 31, 2015 were $48.2 million compared to $59.8 million for the yearended December 31, 2014, a decrease of $11.6 million, or 19%. This decrease was primarily due to reductions in research and development expensespertaining to our BCM and INOpulse for PH-COPD programs and to a decrease in research and development infrastructure expenses. Research and Development Expenses. Total research and development expenses for the year ended December 31, 2015 were $33.4 million comparedto $46.0 million for the year ended December 31, 2014, a decrease of $12.6 million, or 27%. Total research and development expenses consisted of thefollowing:· BCM research and development expenses for the year ended December 31, 2015 were $8.2 million compared to $13.7 million for the year endedDecember 31, 2014, a decrease of $5.5 million, or 40%. The decrease was primarily due to us ceasing further clinical development of BCMfollowing the PRESERVATION I results.· PAH research and development expenses for the year ended December 31, 2015 were $10.7 million compared to $11.3 million for the year endedDecember 31, 2014, a decrease of $0.6 million, or 6%. The decrease was primarily due to the completion of the Phase 2 clinical trial in late-2014and a reversal of an accrual in the year ended December 31, 2015 partially offset by increased costs in anticipation of the start of the Phase 3clinical trials.75· PH-COPD research and development expenses for the year ended December 31, 2015 were $0.0 million compared to $3.0 million for the yearended December 31, 2014, a decrease of $3.0 million, or 100%. The decrease primarily resulted from the completion of the Phase 2a clinical trial inmid-2014.· Research and development infrastructure expenses for the year ended December 31, 2015 were $8.6 million compared to $11.7 million for the yearended December 31, 2014, a decrease of $3.1 million, or 27%. The decrease was due to reductions in infrastructure spending to support ourINOpulse and BCM clinical programs and the discontinuance of cash bonuses. In September 2015, we decided to pay 2015 bonuses by grantingemployees restricted stock awards which will vest over a one-year period from the date of grant. Accordingly, the related cost will be recognizedover such period. · INOpulse engineering expenses for the year ended December 31, 2015 were $6.0 million compared to $6.3 million for the year ended December 31,2014, a decrease of $0.3 million, or 5%. General and Administrative Expenses. General and administrative expenses for the year ended December 31, 2015 were $14.9 million compared to$13.8 million for the year ended December 31, 2014, an increase of $1.1 million, or 8%. The increase was primarily due to restructuring charges of $1.1million and additional costs of operating as a public company, including expenses related to transition services from Ikaria and other professional servicesoffset, in part, by the discontinuance of cash bonuses. In September 2015, we decided to pay 2015 bonuses by granting employees restricted stock awardswhich will vest over a one-year period from the date of grant. Accordingly, the related cost will be recognized over such period. Other Operating Income. Other operating income for the year ended December 31, 2015 was $1.7 million, and we had no operating income for the yearended December 31, 2014. The increase resulted from payments received from Ikaria in connection with entering into the 2015 Services Agreement.Liquidity and Capital Resources In the course of our development activities, we have sustained operating losses and expect such losses to continue over the next several years.We expect to continue to incur significant expenses and operating losses for the foreseeable future as we continue to develop, conduct clinical trialsand seek regulatory approval for our product candidates. Our primary uses of capital are, and we expect will continue to be, compensation and relatedexpenses, third-party clinical research and development services, contract manufacturing services, laboratory and related supplies, clinical costs, legal andother regulatory expenses and general overhead costs.If we obtain regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses. We do not have asales, marketing, manufacture or distribution infrastructure for a pharmaceutical product. To develop a commercial infrastructure, we will have to investfinancial and management resources, some of which would have to be deployed prior to having any certainty of marketing approval.We had cash and cash equivalents of $14.5 million and marketable securities of $5.6 million as of December 31, 2016. Our existing cash and cashequivalents and marketable securities as of December 31, 2016, will be used primarily to fund the first of two INOpulse for PAH Phase 3 trials, in which weenrolled the first patient in June 2016. As of December 31, 2016, we had $7.2 million prepayments of research and development expenses related to ouramended drug supply agreement with Ikaria and the clinical research organization we have partnered with for the first of the two Phase 3 clinical trials forINOpulse for PAH. The corresponding prepayments balance as of December 31, 2015 was $11.3 million.On May 27, 2016, we entered into the Sales Agreement, with Distribution Agents, pursuant to which we may issue and sell shares of our commonstock having an aggregate offering price of up to $5.7 million through the Distribution Agents. Any sales of shares of our common stock pursuant to the SalesAgreement, or the ATM Offering, will be made under our effective shelf registration statement on Form S-3 and the related prospectus supplement. As ofDecember 31, 2016, we have sold 1,025,793 shares for gross and net proceeds of $2.2 million and $2.1 million, respectively.On November 22, 2016, we announced the pricing of a public offering of 17,142,858 Class A Units consisting of an aggregate of 17,142,858 sharesof our common stock and warrants exercisable for up to 17,142,858 shares of our common stock for gross proceeds of $12.0 million, or the SecondaryOffering. The Secondary Offering closed on November 29, 2016, with gross and net proceeds of $12.0 million and $10.9 million, respectively.We continue to pursue potential sources of funding, including equity financing.76We have evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about our ability tocontinue as a going concern within one year beyond the filing of this Annual Report on Form 10-K..We believe that our existing cash and cash equivalents and marketable securities as of December 31, 2016, funds available under the ATM offering,and proceeds that will become available to us upon sale of our state net operating losses (NOL) and R&D tax credits under the State of New Jersey’sTechnology Business Tax Certificate Transfer Program will be sufficient to satisfy our operating cash needs for at least one year after the filing of this AnnualReport on Form 10-K.The Technology Business Tax Certificate Transfer Program enables qualified, unprofitable New Jersey based technology or biotechnologycompanies to sell a percentage of NOL and research and development (R&D) tax credits to unrelated profitable corporations, subject to meeting certaineligibility criteria. Based on consideration of various factors, including application processing time and past trend of benefits made available under theprogram, we believe that it is probable that our plans to sell our NOLs can be effectively implemented to address our short term financial needs. Weparticipated in this program during November 2016 through the sale of R&D tax credits generated in the year ended December 31, 2015. The proceeds fromthis sale were recorded as Income tax benefit.We have based our estimates on assumptions that may prove to be wrong, and we may exhaust our capital resources sooner than we expect. Inaddition, the process of testing product candidates in clinical trials is costly, and the timing of progress in clinical trials is uncertain. Because our productcandidates are in clinical development and the outcome of these efforts is uncertain, we cannot estimate the actual amounts that will be necessary tosuccessfully complete the development and commercialization of our product candidates or whether, or when, we may achieve profitability. Our futurecapital requirements will depend on many factors, including:•progress and cost of our clinical trials and other research and development activities;•our ability to manufacture sufficient supply of our product candidates and the costs thereof;•the cost and timing of seeking regulatory approvals;•the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution for any of ourproduct candidates for which we receive marketing approval;•the number and development requirements of any other product candidates we pursue;•our ability to enter into collaborative agreements and achieve milestones under those agreements;•the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval;•the cost of filing, prosecuting, defending and enforcing patent applications, claims, patents and other intellectual property rights; and•the extent to which we acquire or in-license other products and technologies.Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity anddebt offerings, existing working capital and funding from potential future collaboration arrangements. To the extent that we raise additional capital throughthe future sale of equity or debt, the ownership interest of our existing stockholders will be diluted, and the terms of such securities may include liquidationor other preferences or rights such as anti-dilution rights that adversely affect the rights of our existing stockholders. If we raise additional funds throughstrategic partnerships in the future, we may have to relinquish valuable rights to our technologies, future revenue streams or product candidates or grantlicenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may berequired to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market productcandidates that we would otherwise prefer to develop and market ourselves.If we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate our product development programs orcommercialization efforts. Moreover, if we are unable to obtain additional funds on a timely basis, there will be substantial doubt about our ability tocontinue as a going concern.Cash Flows The following table summarizes our cash flows for the years ended December 31, 2016, 2015 and 2014: 77 Year Ended December 31,(Dollar amounts in thousands) 2016 2015 2014Operating activities $(17,213) $(46,264) $(70,562)Investing activities 12,199 (18,305) —Financing activities 13,207 54,014 87,377 Net change in cash and cash equivalents $8,193 $(10,555) $16,815Net Cash Used in Operating ActivitiesCash used in operating activities for the year ended December 31, 2016 was $17.2 million compared to $46.3 million for the year ended December 31,2015, a decrease of $29.1 million, or 63%. The decrease in cash used in operating activities was primarily due to reduced operating expenses.Cash used in operating activities for the year ended December 31, 2015 was $46.3 million compared to $70.6 million for the year ended December31, 2014, a decrease of $24.3 million, or 34%. The decrease in cash used in operating activities was primarily due to reduced research and developmentexpenses and the recognition in the year ended December 31, 2014 of the $10.8 million restricted cash balance related to the escrow payment due to Ikaria,which was utilized to pay Ikaria during 2015, offset in part by a $6.6 million prepayment made to Ikaria as part of amending our drug supply agreement andan $8.0 million prepayment made to the clinical research organization we have partnered with for the first of two Phase 3 clinical trials for INOpulse for PAH. Net Cash Used in Investing Activities Cash provided by investing activities for the year ended December 31, 2016 was $12.2 million, primarily due to proceeds from the sale of marketablesecurities compared to cash used in investing activities for the year ended December 31, 2015 of $18.3 million, which mostly represented net activity relatedto purchase and sale of our marketable securities. Cash used in investing activities for the year ended December 31, 2015 was $18.3 million, including $0.5 million for capital expenditures related toour new office space in Warren, New Jersey and $22.7 million for the purchase of marketable securities, offset by $4.9 million of proceeds from the sale ofmarketable securities. There were no cash flows from investing activities for the year ended December 31, 2014. Net Cash Provided by Financing Activities Cash provided by financing activities for the year ended December 31, 2016 was $13.2 million, which included the net proceeds from our ATMOffering and Secondary Offering, compared to $54.0 million for the year ended December 31, 2015, which included the net proceeds from our IPO.Cash provided by financing activities for the year ended December 31, 2015 was $54.0 million compared to $87.4 million for the year endedDecember 31, 2014, a decrease of $33.4 million, or 38%. The decrease resulted from the difference between the $53.8 million net proceeds from our IPO inthe year ended December 31, 2015, after deducting underwriting discounts and commissions of $4.2 million and offering costs of $2.0 million paid,compared to the $89.3 million net investment by Ikaria, primarily due to a cash contribution of $80.0 million from Ikaria in the year ended December 31,2014 in connection with the Spin-Out. Contractual Obligations and Commitments The following is a summary of our long-term contractual cash obligations as of December 31, 2016 (in thousands): Payments Due by Period ($)Contractual Obligations Total Less than1 year 1 to 3 years 3 to 5 years More than5 yearsOperating Lease Obligations(1) $4,120 $631 $1,294 $1,338 $857Total $4,120 $631 $1,294 $1,338 $85778(1)Operating lease obligations include the lease agreement we entered into on August 6, 2015 for office space in Warren, New Jersey.Royalty payments and success-based milestones associated with our license and supply agreements with Ikaria have not been included in the abovetable of contractual obligations as we cannot reasonably estimate if or when they will occur.We do not intend to proceed with further clinical development of BCM until and unless we can determine an alternative path forward.Consequently, any future royalty and milestones payments to BioLine would depend on finding a path forward for future clinical development. In the course of our normal business operations, we also enter into agreements with suppliers, contract service providers and others to assist in theperformance of our research and development and manufacturing activities. We can elect to discontinue the work under these contracts and purchase orders atany time with notice, and such contracts and purchase orders do not contain minimum purchase obligations. 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 under applicableSecurities and Exchange Commission rules. 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 beenprepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates andjudgments that affect the reported amounts of assets, liabilities, revenue and expenses and the disclosure of contingent assets and liabilities in our financialstatements. On an ongoing basis, we evaluate our estimates and judgments, including those related to research and development expense, impairment oflong-lived assets, stock-based compensation, common stock warrants, and income taxes. We base our estimates on historical experience, known trends andevents and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about thecarrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under differentassumptions or conditions. While our significant accounting policies are described in Note 2 of the notes to our consolidated financial statements appearing elsewhere in thisAnnual Report on Form 10-K, we believe the following accounting policies to be most critical to the judgments and estimates used in the preparation of ourfinancial statements. Research and Development Expense Research and development costs are expensed as incurred. These expenses include the costs of our proprietary research and development efforts, aswell as costs incurred in connection with certain licensing arrangements. Upfront and milestone payments made to third parties in connection with researchand development collaborations are expensed as incurred up to the point of regulatory approval. Payments made to third parties upon or subsequent toregulatory approval are capitalized and amortized over the remaining useful life of the related product. We also expense the cost of purchased technologyand equipment in the period of purchase if we believe that the technology or equipment has not demonstrated technological feasibility and does not have analternative future use. Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities aredeferred and are recognized as research and development expense as the related goods are delivered or the related services are performed. As part of the process of preparing our financial statements, we are required to estimate a portion of our prepaid and accrued research expenses. Thisprocess involves reviewing open contracts and purchase orders, communicating with applicable personnel to identify services that have been performed onour behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwisenotified of actual cost. We make such estimates of our incurred research and development expenses as of each balance sheet date in our financial statementsbased on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and makeadjustments if necessary. Examples of estimated prepaid and accrued research and development expenses include:· fees paid to contract research organizations in connection with clinical trials;79· fees paid to investigative sites in connection with clinical trials; and· fees paid to contract manufacturers in connection with the production of clinical trial materials.We base our expenses related to research and development and clinical trials on actual costs incurred in addition to our estimates of the servicesreceived and efforts expended pursuant to contracts with multiple third parties, including research institutions and contract research organizations thatconduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and mayresult in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completionof clinical trial milestones. In accruing the research and development service fees, we consider the terms of each agreement, the time period over which theservices will be performed and the level of effort required to complete the service. If the actual timing of the performance of the services or the level of effortvaries from our estimate, we adjust the accrual accordingly. Although we do not expect our estimates to be materially different from amounts actuallyincurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and mayresult in us reporting amounts that are too high or too low in any particular period. Common Stock Warrant LiabilityWe account for common stock warrants issued as freestanding instruments in accordance with applicable accounting guidance provided in ASCTopic 480, Distinguishing Liabilities From Equity (ASC Topic 480), as either liabilities or as equity instruments depending on the specific terms of thewarrant agreement. We classify warrant liabilities on the consolidated balance sheet as current liabilities, which are revalued at each balance sheet datesubsequent to the initial issuance. Changes in the fair value of the warrants are reflected in the consolidated statement of operations as “Change in fair valueof common stock warrant liability.” We use the Black-Scholes-Merton pricing model to value the related warrant liabilities. Certain assumptions used in themodel include expected volatility, dividend yield, risk-free interest rate, and expected term. Refer to Note 6 of the notes to our consolidated financialstatements appearing elsewhere in this Annual Report on Form 10-K for a detailed description of our accounting for warrant liabilities.Stock-Based Compensation We issue, and prior to the Spin-Out Ikaria, our former parent, issued, stock-based awards to employees and non-employees in the form of stock options,restricted stock awards, or RSAs, and restricted stock units, or RSUs. The stock-based compensation expense recorded for the periods prior to the Spin-Outpresented in our audited financial statements, included elsewhere in this Annual Report on Form 10-K, represents an allocation of Ikaria’s stock-basedcompensation expense based on the allocation percentages of our cost centers, which were determined based on specific identification or the proportionatepercentage of employee time or headcount to the respective total Ikaria employee time or headcount. Because certain of these amounts relate to Ikaria stock-based awards, the amounts presented are not necessarily indicative of our future performance and do not necessarily reflect the stock-based compensation orcompensation expense that we would have experienced as a stand-alone company for these periods. We account for our stock-based compensation in accordance with Accounting Standards Codification, or ASC, 718 Compensation- StockCompensation, which establishes accounting for share-based awards, including stock options and restricted stock, exchanged for services and requirescompanies to expense the estimated fair value of these awards over the requisite service period. We recognize stock-based compensation expense inoperations based on the fair value of the award on the date of the grant. The resulting compensation expense is recognized on a straight-line basis over therequisite service period or sooner if the awards immediately vest. We use the Black-Scholes-Merton option pricing model to value our stock option awards.Refer to Note 9 of the notes to our consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K for a detailed description ofour accounting for stock-based compensation. Recently Adopted Accounting StandardsIn May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2014-09, “Revenue fromContracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goodsor services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard iseffective for us on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. We are assessing ASU2014-09’s impact and will adopt it when effective.80In August 2014, the FASB issued ASU, 2014-15, “Presentation of Financial Statements - Going Concern: Disclosure of Uncertainties about anEntity’s Ability to Continue as a Going Concern.” This guidance clarifies that an entity’s management should evaluate whether there are conditions orevents, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date thatthe financial statements are issued. The amendments in this update are effective for annual reporting periods ending after December 15, 2016, and annual andinterim periods thereafter, and early application is permitted. We adopted ASU 2014-15 during the year ended December 31, 2016. Note 3 of the notes to ourconsolidated financial statements appearing elsewhere in this Annual Report on Form 10-K incorporates the disclosure requirements from the adoption ofASU 2014-15.In January 2016, the FASB issued ASU 2016-01, "Financial Instruments - Overall - Recognition and Measurement of Financial Assets and FinancialLiabilities," which addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This standard will be effectivefor fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are assessing ASU 2016-01’s impact and willadopt it when effective.In February 2016, the FASB issued ASU 2016-02, "Leases," which is intended to improve financial reporting about leasing transactions. Thisstandard requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months.This standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are assessing ASU2016-02’s impact and will adopt it when effective.In March 2016, the FASB issued ASU 2016-09, "Compensation - Stock Compensation - Improvements to Employee Share-Based PaymentAccounting" which provides for simplification of the accounting for share-based payment transactions, including the income tax consequences, classificationof awards as either equity or liabilities, and classification on the statement of cash flows. This standard will be effective for fiscal years beginning afterDecember 15, 2016, including interim periods within those fiscal years. We do not believe that the adoption of this standard will have a material impact onour consolidated financial statements.In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows: Clarification of Certain Cash Receipts and Cash Payments”, whicheliminates the diversity in practice related to the classification of certain cash receipts and payments in the statement of cash flows, by adding or clarifyingguidance on eight specific cash flow issues. ASU 2016-15 is effective for annual and interim reporting periods beginning after December 15, 2017 and earlyadoption is permitted. ASU 2016-15 provides for retrospective application for all periods presented. We are assessing ASU 2016-15’s impact and will adopt itwhen effective.In November 2016, the FASB issued ASU 2016-18 "Statement of Cash Flows: Restricted Cash", which eliminates the diversity in practice related tothe inclusion of restricted cash in the statement of cash flows by requiring that a statement of cash flows include the change during the period in restrictedcash when reconciling beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for annual andinterim reporting periods beginning after December 15, 2017 and early adoption is permitted. ASU 2016-18 provides for retrospective application for allperiods presented. We are assessing ASU 2016-18’s impact and will adopt it when effective. JOBS Act We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. We will remain an emerginggrowth company until the earlier of: (i) the last day of the fiscal year in which we have total annual gross revenues of $1 billion or more; (ii) December 31,2020; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we aredeemed to be a large accelerated filer under the rules of the SEC, which means the first day of the year following the first year in which the market value ofour common stock that is held by non-affiliates exceeds $700 million as of June 30. For so long as we remain an emerging growth company, we are permittedand intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies.These exemptions include: •not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002;•not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatoryaudit 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; and81•exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any goldenparachute payments not previously approved. We may choose to take advantage of some, but not all, of the available exemptions. We have taken advantage of reduced reporting burdens in ourfilings with the SEC. In particular, we have not included all of the executive compensation information that would be required if we were not an emerginggrowth company. We cannot predict whether investors will find our common stock less attractive if we rely on certain or all of these exemptions. If someinvestors 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 morevolatile. In addition, the JOBS Act provides that an emerging growth company may take advantage of an extended transition period for complying with new orrevised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards wouldotherwise apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, we are subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.Item 7A. Quantitative and Qualitative Disclosures About Market Risk We are exposed to market risk related to changes in interest rates. As of December 31, 2016, we had cash and cash equivalents of $14.5 million, consistingprimarily of demand deposits with U.S. banking institutions and marketable securities of approximately $5.6 million. Our primary exposure to market risk isinterest rate sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because our investments are in cash and cashequivalents, federally insured certificates of deposit and corporate or agency bonds rated A or better. Due to the nature of our deposits and the low risk profileof our investments, an immediate 10% change in interest rates would not have a material effect on the fair market value of our deposits.

(formerly Bellerophon Therapeutics LLC)and subsidiaries as of December 31, 2016 and 2015, and the related consolidated statements of operations, comprehensive loss, changes instockholders’/members’ equity and invested deficit and cash flows for each of the years in the three-year period ended December 31, 2016. Theseconsolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidatedfinancial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require thatwe plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includesexamining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.

Notes to Consolidated Financial Statements (1) Organization and Nature of the Business Bellerophon Therapeutics, Inc., or the Company, is a clinical-stage therapeutics company focused on developing innovative products at theintersection of drugs and devices that address significant unmet medical needs in the treatment of cardiopulmonary diseases. The focus of the Company’sclinical program is the continued development of its nitric oxide therapy for patients with pulmonary hypertension, or PH, using its proprietary deliverysystem, INOpulse, with pulmonary arterial hypertension, or PAH, representing the lead indication. The Company has three wholly-owned subsidiaries:Bellerophon BCM LLC, a Delaware limited liability company; Bellerophon Pulse Technologies LLC, a Delaware limited liability company; andBellerophon Services, Inc., a Delaware corporation.The Company’s business is subject to significant risks and uncertainties, including but not limited to: •The risk that the Company will not achieve success in its research and development efforts, including clinical trials conducted by it or itspotential collaborative partners. •The expectation that the Company will experience operating losses for the next several years. •Decisions by regulatory authorities regarding whether and when to approve the Company’s regulatory applications as well as their decisionsregarding labeling and other matters which could affect the commercial potential of the Company’s products or product candidates. •The risk that the Company will fail to obtain adequate financing to meet its future operational and capital needs.•The risk that the Company will be unable to obtain additional funds on a timely basis and hence there will be substantial doubt about its abilityto continue as a going concern. •The risk that key personnel will leave the Company and/or that the Company will be unable to recruit and retain senior level officers to manageits business. The Company was formerly the research and development operating segment of Ikaria, Inc. (a subsidiary of Mallinckrodt plc), or Ikaria. During thethird quarter of 2013 in conjunction with Ikaria’s financing activities, Ikaria began reporting financial information for two operating segments: its researchand development business and its commercial business. During the fourth quarter of 2013, Ikaria completed an internal reorganization of the assets andsubsidiaries of its two operating segments. In connection with the internal reorganization, Ikaria formed Bellerophon Therapeutics LLC as a new wholly-owned subsidiary and transferred the research and development-related assets related to INOpulse for PAH and INOpulse for PH-COPD to the Companyand/or its subsidiaries.On February 2, 2015, the Company effected a reverse unit split of its outstanding units at a ratio of one unit for every 12.5257 units previously held.All unit and per unit data included in these consolidated financial statements reflect the reverse unit split. In February 2015, the Company converted from alimited liability company to a C-corporation. For periods prior to February 2015, references to the Company refer to Bellerophon Therapeutics, LLC. On December 24, 2013, Ikaria and Madison Dearborn Partners, or MDP, entered into an agreement and plan of merger, under which MDP wouldacquire a majority ownership position in Ikaria and existing shareholders retained a minority ownership position in Ikaria through certain mergertransactions, or the Merger. On February 12, 2014, prior to the Merger, Ikaria distributed all of the Company’s outstanding units to Ikaria’s stockholders in a pro rata distributionthrough a special dividend, which is referred to as the Spin-Out. In the Spin-Out, each holder of Ikaria common stock received one voting limited liabilitycompany interest in the Company for each share of Ikaria common stock held. In connection with the Spin-Out, $80.0 million of cash was distributed to the Company. At the time of the Spin-Out, $18.5 million of the $80.0million cash held by the Company was deposited in escrow to guarantee payment of the monthly services fees payable by the Company to Ikaria in exchangefor the services to be provided by Ikaria pursuant to the Company’s89transition services agreement with Ikaria, or the TSA, during the 24 months following the Spin-Out. See Note 12- Related-Party Transactions. On July 9,2015, the Company entered into an amendment to the TSA advancing the termination date from February 9, 2016 to September 30, 2015. Pursuant to thisamendment, during October 2015, the Company received from escrow $3.3 million, which is equal to the amount it deposited to pay amounts owed to Ikariaunder the TSA for the remainder of the original period. On February 19, 2015, the Company completed the sale of 5,000,000 shares of common stock, or the IPO, at a price to the public of $12.00 per share,resulting in net proceeds to the Company of $51.9 million after deducting underwriting discounts and commissions of $4.2 million and offering costs of $3.9million. The Company’s common stock began trading on the NASDAQ Global Market under the symbol “BLPH” on February 13, 2015. (2) Summary of Significant Accounting Policies (a) Basis of Presentation The financial statements have been prepared in accordance with U.S. generally accepted accounting principles or GAAP. Intercompany balances andtransactions have been eliminated. For periods prior to the Spin-Out, the financial statements were carved out of the consolidated financial statements ofIkaria. Although the financial statements prior to the Spin-Out were prepared on a combined carve-out basis, the financial statements for all periods presentedhave been labeled “consolidated” financial statements for ease of reference since the most recent balance sheets at December 31, 2016 and 2015 areconsolidated balance sheets. At the date of the Spin-Out, the historical accumulated deficit of approximately $182.0 million based on the carve-out financialstatements through February 11, 2014 was eliminated in the transfer of net assets to the Company. The net loss for the period February 12, 2014 throughDecember 31, 2014 of $54.2 million has been reflected as the accumulated deficit on the Statement of Changes in Stockholders’/Members’ Equity andInvested Deficit, representing the net loss since the date of the Spin-Out. Net assets contributed to the Company in the Spin-Out were $75.6 million,including cash of $80.0 million. The results of operations and cash flows for the year ended December 31, 2016 and 2015 and from February 12, 2014through December 31, 2014 and the balance sheet as of December 31, 2016 and 2015 represent actual results and the financial position of the Company on astand-alone basis. The Company operates in one reportable segment and solely within the United States. Accordingly, no segment or geographic informationhas been presented. The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets andliabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of costs and expenses during thereporting period, including prepaid and accrued research and development expenses, stock-based compensation, common stock warrant liability and incometaxes. Actual results could differ from those estimates. For periods prior to the Spin-Out, the financial statements were carved out of the consolidated financial statements of Ikaria. Management believesthat the statements of operations for the periods prior to the Spin-Out (which include a period of forty-two days prior to the Spin-Out in the year endedDecember 31, 2014) include reasonable allocations of costs and expenses incurred by Ikaria which benefited the Company. However, such amounts may notbe indicative of the actual level of costs and expenses that would have been incurred by the Company if it had operated as an independent stand-alonecompany or of the costs and expenses expected to be incurred in the future. As such, the financial information for the year ended December 31, 2014 may notnecessarily reflect the results of operations and cash flows of the Company had it been an independent stand-alone company for the period, or the results ofoperations and cash flows expected in the future. Direct and indirect costs related to the Company for INOpulse for PAH, INOpulse for PH-COPD and Bioabsorbable Cardiac Matrix, or BCM, clinicalprograms have been allocated to the Company for the period prior to February 12, 2014. These allocations were based on either a specific identification basisor, when specific identification was not practicable, proportional cost allocation methods, such as time and wage studies, depending on the nature of theexpense. All allocations were based on actual costs incurred. For purposes of allocating non-project specific expenses, each departmental head providedinformation as to the percentage of employee time incurred on behalf of the Company. Allocations of general and administrative expenses by Ikaria to the Company for periods prior to February 12, 2014 include allocations of corporatemanagement, finance, information technology, legal, human resources and other overhead expenses, based on an approximate pro-rata headcount ofemployees. (b)Cash and Cash Equivalents 90The Company considers all highly liquid investments with an original maturity date of three months or less to be cash equivalents. All investmentswith maturities of greater than three months from date of purchase are classified as available-for-sale marketable securities. (c)Stock-Based Compensation The Company accounts for its stock-based compensation in accordance with Accounting Standards Codification, or ASC, 718 Compensation- StockCompensation, which establishes accounting for share-based awards, including stock options and restricted stock, exchanged for services and requirescompanies to expense the estimated fair value of these awards over the requisite service period. The Company recognizes stock-based compensation expensein operations based on the fair value of the award on the date of the grant. The resulting compensation expense is recognized on a straight-line basis over therequisite service period or sooner if the awards immediately vest. The Company determines the fair value of stock options issued using a Black-Scholes-Merton option pricing model. Certain assumptions used in the model include expected volatility, dividend yield, risk-free interest rate, and expected term.For restricted stock, the fair value is the closing market price per share on the grant date. See Note 9 - Stock-Based Compensation for a description of theseassumptions. Prior to the date of the Spin-Out, stock-based compensation expense for the Company represented an allocation of Ikaria’s stock-based compensationexpense based on the allocation percentages of the Company’s cost centers, which were determined based on specific identification or the proportionatepercentage of employee time or headcount to the respective total Ikaria employee time or headcount. (d)Common Stock Warrant LiabilityThe Company accounts for common stock warrants issued as freestanding instruments in accordance with applicable accounting guidance providedin ASC Topic 480, Distinguishing Liabilities From Equity (ASC Topic 480), as either liabilities or as equity instruments depending on the specific terms ofthe warrant agreement. The Company classifies warrant liabilities on the consolidated balance sheet as long-term liabilities, which are revalued at eachbalance sheet date subsequent to the initial issuance. Changes in the fair value of the warrants are reflected in the consolidated statement of operations as“Change in fair value of common stock warrant liability.” The Company uses the Black-Scholes-Merton pricing model to value the related warrant liabilities.Certain assumptions used in the model include expected volatility, dividend yield, risk-free interest rate, and expected term. See Note 6 - Warrants for adescription of these assumptions.(e)Income Taxes Prior to its conversion to a Delaware corporation in February 2015, the Company was a Delaware limited liability company, or LLC, that passedthrough income and losses to its members for U.S. federal and state income tax purposes. As a result of its conversion to a Delaware corporation, theCompany recognized deferred income taxes through income tax expense related to temporary differences that existed as of the date of its tax status change.The Company uses the asset and liability approach to account for income taxes as required by ASC 740, Income Taxes, which requires the recognition ofdeferred tax assets and liabilities for the expected future tax consequences attributable to differences between the financial statement carrying amounts ofexisting assets and liabilities and their respective tax bases. Valuation allowances are provided when necessary to reduce deferred tax assets to the amountexpected to be realized, on a more likely than not basis. The Company recognizes the benefit of an uncertain tax position that it has taken or expects to takeon income tax returns it files if such tax position is more likely than not to be sustained on examination by the taxing authorities, based on the technicalmerits of the position. These tax benefits are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimateresolution. As of the date of the conversion to a taxable corporation, the Company recognized approximately $17.9 million of deferred tax assets whichconsisted principally of excess tax-over-book basis in intangible assets and property, plant and equipment and certain accruals that were transferred from thelimited liability company to the corporation. The Company also recognized a full valuation allowance since it had a cumulative loss position and nopositive evidence of taxable income to support recovery of the deferred tax assets. The Company incurred transaction costs of approximately $8.1 million inconnection with the IPO which were recorded as a reduction of equity. These costs are nondeductible until and if the Company liquidates or terminatesoperations, which is not expected in the foreseeable future. Therefore, the Company did not recognize a deferred tax asset for such costs.(f)Marketable Securities91The Company’s marketable securities consist of federally insured certificates of deposit classified as available-for-sale that are recorded at amortizedcost, which approximates fair value, and corporate or agency bonds classified as available-for-sale that are recorded at fair value. Unrealized gains and lossesare reported as accumulated other comprehensive (loss) income, except for losses from impairments which are determined to be other-than-temporary.Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of netloss and are included in interest and other income, at which time the average cost basis of these securities are adjusted to fair value. Fair values are based onquoted market prices at the reporting date. Interest on available-for-sale securities are included in interest and other income.(g)Research and Development Expense Research and development costs are expensed as incurred. These expenses include the costs of the Company’s proprietary research and developmentefforts, as well as costs incurred in connection with certain licensing arrangements. Upfront and milestone payments made to third parties in connection withresearch and development collaborations are expensed as incurred up to the point of regulatory approval. Payments made to third parties upon or subsequentto regulatory approval are capitalized and amortized over the remaining useful life of the related product. The Company also expenses the cost of purchasedtechnology and equipment in the period of purchase if it believes that the technology or equipment has not demonstrated technological feasibility and itdoes not have an alternative future use. Nonrefundable advance payments for goods or services that will be used or rendered for future research anddevelopment activities are deferred and are recognized as research and development expense as the related goods are delivered or the related services areperformed.(h) ReclassificationCertain prior year balances have been reclassified to conform to the current year presentation.(i) New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2014-09, “Revenue fromContracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goodsor services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard iseffective for the Company on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. The Companyis assessing ASU 2014-09’s impact and will adopt it when effective.In August 2014, the FASB issued ASU, 2014-15, “Presentation of Financial Statements - Going Concern: Disclosure of Uncertainties about anEntity’s Ability to Continue as a Going Concern.” This guidance clarifies that an entity’s management should evaluate whether there are conditions orevents, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date thatthe financial statements are issued. The amendments in this update are effective for annual reporting periods ending after December 15, 2016, and annual andinterim periods thereafter, and early application is permitted. The Company adopted ASU 2014-15 during the year ended December 31, 2016. Note 3 -Liquidity incorporates the disclosure requirements from the adoption of ASU 2014-15.In January 2016, the FASB issued ASU 2016-01, "Financial Instruments - Overall - Recognition and Measurement of Financial Assets and FinancialLiabilities," which addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This standard will be effectivefor fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is assessing ASU 2016-01’s impact andwill adopt it when effective.In February 2016, the FASB issued ASU 2016-02, "Leases," which is intended to improve financial reporting about leasing transactions. Thisstandard requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months.This standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company isassessing ASU 2016-02’s impact and will adopt it when effective.In March 2016, the FASB issued ASU 2016-09, "Compensation - Stock Compensation - Improvements to Employee Share-Based PaymentAccounting" which provides for simplification of the accounting for share-based payment transactions, including the income tax consequences, classificationof awards as either equity or liabilities, and classification on the statement of cash flows. This standard will be effective for fiscal years beginning afterDecember 15, 2016, including interim periods within those fiscal years. The Company does not believe that the adoption of this standard will have a materialimpact on our consolidated financial statements.92In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows: Clarification of Certain Cash Receipts and Cash Payments”, whicheliminates the diversity in practice related to the classification of certain cash receipts and payments in the statement of cash flows, by adding or clarifyingguidance on eight specific cash flow issues. ASU 2016-15 is effective for annual and interim reporting periods beginning after December 15, 2017 and earlyadoption is permitted. ASU 2016-15 provides for retrospective application for all periods presented. The Company is assessing ASU 2016-15’s impact andwill adopt it when effective.In November 2016, the FASB issued ASU 2016-18 "Statement of Cash Flows: Restricted Cash", which eliminates the diversity in practice related tothe inclusion of restricted cash in the statement of cash flows by requiring that a statement of cash flows include the change during the period in restrictedcash when reconciling beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for annual andinterim reporting periods beginning after December 15, 2017 and early adoption is permitted. ASU 2016-18 provides for retrospective application for allperiods presented. The Company is assessing ASU 2016-18’s impact and will adopt it when effective.(3) Liquidity In the course of its development activities, the Company has sustained operating losses and expects such losses to continue over the next severalyears. The Company expects to continue to incur significant expenses and operating losses for the foreseeable future as it continues the development andclinical trials of, and seek regulatory approval for, its product candidates. The Company's primary uses of capital are, and it expects will continue to be,compensation and related expenses, third-party clinical research and development services, contract manufacturing services, laboratory and related supplies,clinical costs, legal and other regulatory expenses and general overhead costs.The Company had cash and cash equivalents of $14.5 million and marketable securities of $5.6 million as of December 31, 2016. The Company's existing cash and cash equivalents and marketable securities as of December 31, 2016 will be used primarily to fund the first of twoINOpulse for PAH Phase 3 trials, in which the Company enrolled the first patient in June 2016, and to a lesser extent for the Phase 2 trials for PH-COPD andPH-IPF. In addition, as of December 31, 2016, the Company had $7.2 million prepayments of research and development expenses related to its amended drugsupply agreement with Ikaria and the clinical research organization it has partnered with for the first of the two Phase 3 clinical trials for INOpulse for PAH.The corresponding prepayments balance as of December 31, 2015 was $11.3 million. These prepayment amounts are presented on the respectiveconsolidated balance sheets as follows (in thousands): December 31, 2016 December 31, 2015Prepaid expenses and other current assets5,842 4,551Other non-current assets1,406 6,701 7,248 11,252On May 5, 2016, the Company filed a shelf registration statement with the Securities and Exchange Commission, or the SEC, on Form S-3, which asamended became effective on May 23, 2016. The shelf registration will allow the Company to issue, from time to time at prices and on terms to be determinedprior to the time of any such offering, up to $30.0 million of any combination of the Company’s common stock, preferred stock, debt securities, warrants,rights, purchase contracts or units, either individually or in units.On May 27, 2016, the Company entered into a Sales Agreement, with FBR Capital Markets & Co. and MLV & Co. LLC, or Distribution Agents,pursuant to which the Company may issue and sell shares of the Company's common stock having an aggregate offering price of up to $5.7 million throughthe Distribution Agents. Any sales of shares of the Company's common stock pursuant to the Sales Agreement, or the ATM Offering, will be made under theCompany’s effective shelf registration statement on Form S-3 and the related prospectus supplement dated May 27, 2016 and filed with the SEC on May 27,2016. As of December 31, 2016, the Company had sold 1,025,793 shares for gross and net proceeds of $2.2 million and $2.1 million, respectively.On November 22, 2016, the Company filed a registration statement with the SEC, on Form S-1, which as amended became effective on November22, 2016. On November 29, 2016, the Company completed the sale of 17,142,858 Class A Units consisting of an aggregate of 17,142,858 shares of itscommon stock and warrants exercisable for up to 17,142,858 shares of its common stock at a price of $0.70 per Unit, or the Secondary Offering, resulting innet proceeds of $10.9 million, after deducting placement fees of $0.8 million and offering costs of $0.3 million. Each warrant will have an exercise price perfull93share of common stock equal to $0.80, will be immediately exercisable and will expire 5 years from the date on which such warrant becomes exercisable. Thewarrants require cash settlement by the Company under certain situations.The Company continues to pursue potential sources of funding, including equity financing. The Company evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about its ability tocontinue as a going concern within one year beyond the filing of this Annual Report on Form 10-K..Based on such evaluation, management believes that the Company’s existing cash and cash equivalents and marketable securities as ofDecember 31, 2016, funds available under the ATM offering, and proceeds that will become available to the Company upon sale of the Company’s State netoperating losses (NOL) and R&D tax credits under the State of New Jersey’s Technology Business Tax Certificate Transfer Program will be sufficient tosatisfy the Company’s operating cash needs for at least one year after the filing of this Annual Report.The Technology Business Tax Certificate Transfer Program enables qualified, unprofitable New Jersey based technology or biotechnologycompanies to sell a percentage of NOL and research and development (R&D) tax credits to unrelated profitable corporations, subject to meeting certaineligibility criteria. Based on consideration of various factors, including application processing time and past trend of benefits made available under theprogram, management believes that it is probable that the Company’s plans to sell NOLs can be effectively implemented to address the Company’s short termfinancial needs. The Company participated in this program during November 2016 through the sale of R&D tax credits generated in the year ended December31, 2015. The proceeds from this sale were recorded as Income tax benefit. The Company’s estimates and assumptions may prove to be wrong, and the Company may exhaust its capital resources sooner than expected. The processof testing product candidates in clinical trials is costly, and the timing of progress in clinical trials is uncertain. Because the Company’s product candidatesare in clinical development and the outcome of these efforts is uncertain, the Company cannot estimate the actual amounts that will be necessary tosuccessfully complete the development and commercialization, if approved, of its product candidates or whether, or when, the Company may achieveprofitability.Until such time, if ever, as the Company can generate substantial product revenues, its expects to finance its cash needs through a combination ofequity and debt offerings, existing working capital and funding from potential future collaboration arrangements. To the extent that the Company raisesadditional capital through the future sale of equity or debt, the ownership interest of its existing stockholders will be diluted, and the terms of such securitiesmay include liquidation or other preferences or rights such as anti-dilution rights that adversely affect the rights of our existing stockholders. If the Companyraises additional funds through strategic partnerships in the future, it may have to relinquish valuable rights to its technologies, future revenue streams orproduct candidates or grant licenses on terms that may not be favorable to it. If the Company is unable to raise additional funds through equity or debtfinancings when needed, it may be required to delay, limit, reduce or terminate its product development or future commercialization efforts or grant rights todevelop and market product candidates that it would otherwise prefer to develop and market itself. If the Company is unable to raise capital when needed, it could be forced to delay, reduce or eliminate its product development programs orcommercialization efforts. Moreover, if the Company is unable to obtain additional funds on a timely basis, there will be substantial doubt about its ability tocontinue as a going concern.(4) Marketable SecuritiesThe Company considers all of its current investments to be available-for-sale.

As the warrants, under certain situations, could require cash settlement, the warrants were classified as liabilities andare recorded at estimated fair value using a Black-Scholes-Merton pricing model.

(7) Fair Value Measurements Assets and liabilities recorded at fair value on the balance sheets are categorized based upon the level of judgment associated with the inputs used tomeasure the fair value. Level inputs are as follows: 95•Level 1 - Values are based on unadjusted quoted prices for identical assets or liabilities in an active market which the company has the ability toaccess at the measurement date. •Level 2 - Values are based on quoted market prices in markets where trading occurs infrequently or whose values are based on quoted prices ofinstruments with similar attributes in active markets. •Level 3 - Values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair valuemeasurement. These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset. The following table summarizes fair value measurements by level at December 31, 2016 for financial instruments measured at fair value on arecurring basis (in thousands): (Dollar amounts in thousands) Level 1Level 2Level 3TotalMarketable securities$—$5,571$—$5,571Common stock warrant liabilities $— $— $5,215 $5,215 The following table summarizes fair value measurements by level at December 31, 2015 for financial instruments measured at fair value on arecurring basis (in thousands): (Dollar amounts in thousands) Level 1Level 2Level 3TotalMarketable securities$—$17,807$—$17,807 There were no common stock warrant liabilities as of December 31, 2015.The Company uses a Black-Scholes-Merton option pricing model to value its common stock warrants. The significant unobservable inputs used incalculating the fair value of common stock warrants represent management’s best estimates and involve inherent uncertainties and the application ofmanagement’s judgment. For volatility, the Company uses comparable public companies as a basis for its expected volatility to calculate the fair value ofcommon stock warrants due to its limited history as a public company. The risk-free interest rate is based on U.S. Treasury notes with a term approximatingthe expected term of the common stock warrant. Any significant increases or decreases in the unobservable inputs, with the exception of the risk-free interestrate, may result in significantly higher or lower fair value measurements. The following are the assumptions used in estimating the fair value of warrants issued as of November 29, 2016 and December 31, 2016: December 31, 2016 November 29, 2016Valuation assumptions: Risk-free interest rate1.91% 1.78%Expected volatility83.73% 81.98%Expected term (in years)4.9 5.0Dividend yield—% —%(8) Restructuring Charges On July 27, 2015, the Company announced that its PRESERVATION I clinical trial for its BCM product candidate did not meet its primary orsecondary endpoints. Following these results, on September 11, 2015, the Board of Directors of the Company approved a staff reduction plan in order toreduce operating expenses and conserve cash resources, or the Restructuring. The Restructuring included a workforce reduction of approximately 20 peopleand was completed by the end of 2015.The Company offered severance benefits to the affected employees, including cash severance payments. Each affected employee’s eligibility for theseverance benefits was contingent upon such employee’s execution (and non-revocation) of a separation agreement, which includes a general release ofclaims against the Company. 96The following table summarizes restructuring activities for the year ended December 31, 2016 and 2015 (in thousands): December 31, 2016 December 31, 2015Opening balance (a)$969 —Charged to research and development expense — 321Charged to general and administrative expense — 1,053Reversals to general and administrative expenses (b) (352) —Cash payments(507) (405)Accrual balance at December 31, 2016 (a)$110 $969(a) Included in Accrued expenses.(b) Pursuant to resolution of certain matters that resulted in cessation of severance payments(9) Stock-Based Compensation Determining the appropriate fair value of stock-based awards requires the input of subjective assumptions, including the fair value of the Company’sunits (prior to the IPO date) and for options, the expected term of the option and expected volatility. The Company uses the Black-Scholes-Merton optionpricing model to value its stock option awards. The assumptions used in calculating the fair value of stock-based awards represent management’s bestestimates and involve inherent uncertainties and the application of management’s judgment. As a result, if factors change and management uses differentassumptions, stock-based compensation expense could be materially different for future awards. The expected term of stock options is estimated using the“simplified method,” as the Company has no historical information to develop reasonable expectations about future exercise patterns and post-vestingemployment termination behavior for its stock options grants. The simplified method is based on the average of the vesting tranches and the contractual lifeof each grant. For volatility, the Company uses comparable public companies as a basis for its expected volatility to calculate the fair value of option grantsdue to its limited history as a public company. The risk-free interest rate is based on U.S. Treasury notes with a term approximating the expected term of theoption. For restricted stock, the fair value is the closing market price per share on the grant date. The estimation of the number of stock awards that willultimately vest requires judgment, and to the extent actual results or revised estimates differ from the Company’s current estimates, such amounts will berecorded as an adjustment in the period in which estimates are revised. Bellerophon 2015 Equity Incentive Plan During 2015, the Company adopted the 2015 Equity Incentive Plan, or the 2015 Plan, which provides for the grant of options, restricted stock andother forms of equity compensation. As of December 31, 2016, there was approximately $3.0 million of total unrecognized compensation expense related to unvested stock awards. Thisexpense is expected to be recognized over a weighted-average period of 2.3 years. No tax benefit was recognized during the years ended December 31, 2016, 2015 and 2014 related to stock-based compensation expense since theCompany incurred operating losses and has established a full valuation allowance to offset all the potential tax benefits associated with its deferred taxassets. Options Compensation expense is measured based on the fair value of the option on the grant date and is recognized on a straight-line basis over therequisite service period, or sooner if vesting occurs sooner than on a straight-line basis. Options are forfeited if the employee ceases to be employed by theCompany prior to vesting. During 2014, the Company adopted the 2014 Equity Incentive Plan, or the 2014 Plan, which provides for the grant of options. Following theeffectiveness of the Company’s registration statement filed in connection with its IPO, no options may be granted under the 2014 Plan. The awards grantedunder the 2014 Plan generally have a vesting period of four years, of which 25% of the awards vest on the second anniversary of grant date, 25% vest on thethird anniversary and the remaining 50% vest on the fourth anniversary of the grant date. The awards granted under the 2015 Plan have a vesting period ofeither97three or four years, of which equal annual installments vest over the vesting period either beginning on the date of grant or on the one year anniversary of thedate of grant. The weighted average grant-date fair value of options issued during the year ended December 31, 2016, 2015 and 2014 was $0.52, $6.55 and $9.98,respectively. The following are the weighted average assumptions used in estimating the fair value of options issued during the years ended December 31,2016, 2015 and 2014.

There were 618,212 BellerophonOptions issued as a result of the adjustment of Ikaria stock options. The vesting of each Adjusted Ikaria Option and Bellerophon Option was fully acceleratedon the date of the Spin-Out and all related compensation expense was recognized as an expense by Ikaria. Prior to and in connection with the Spin-Out, the exercise price of each Adjusted Ikaria Option and Bellerophon Option was adjusted by allocatingthe relative post Spin-Out estimated fair values of Ikaria and the Company in a ratio of 85% and 15%, respectively, to the original Ikaria option exerciseprice. The expiration date of the options was not modified. The Company’s allocable portion of Ikaria’s stock-based compensation expense related to optionsfor the period from January 1, 2014 through February 11, 2014 was approximately $0.1 million. A summary of option activity under the assumed Ikaria 2007 stock option plan and the assumed Ikaria 2010 long term incentive plan for the yearsended December 31, 2016, 2015 and 2014 is presented below: 99Ikaria Equity Incentive Plans for Periods Prior toFebruary 12, 2014Shares Range ofExercise Price WeightedAverageExercise Price WeightedAverageRemainingContractualLife (in years)Options issued and vested at date of Spin-Out as of February 12, 2014618,212 $0.26-17.92 $7.24 Exercised(8,182) 7.77-8.77 7.99 Forfeited(32,055) 7.77-14.91 9.39 Options outstanding, vested and exercisable as of December 31, 2014577,975 $0.26-17.92 $7.11 4.5Exercised(126,499) 1.13-7.77 1.47 Forfeited(337,767) 7.77-17.92 8.61 Options outstanding, vested and exercisable as of December 31, 2015113,709 $0.26-17.92 $8.93 5.2Forfeited(26,340) 0.26-17.92 8.23 Options outstanding, vested and exercisable as of December 31, 201687,369 $7.77-17.92 $9.14 4.3 There were no options exercised during the year ended December 31, 2016. The intrinsic value of options exercised during the year ended December31, 2015 and 2014 was $0.4 million and de minimis, respectively. The intrinsic value of options outstanding, vested and exercisable as of December 31,2016 was de minimis.Restricted Stock Units In February 2014, prior to the Spin-Out, each Ikaria restricted stock unit, or RSU, was adjusted such that it became an RSU with respect to the samenumber of shares of Ikaria non-voting common stock as were subject to the Ikaria RSU, or an Adjusted Ikaria RSU, and an RSU with respect to the samenumber of non-voting limited liability company units of the Company as were subject to the Ikaria RSU, or a Bellerophon RSU. In connection with theMerger and the Spin-Out, the vesting of each Adjusted Ikaria RSU and Bellerophon RSU was fully accelerated. The compensation expense incurred upon theacceleration of the RSUs was recognized by Ikaria. Fully vested Bellerophon RSUs of 372,947 became Bellerophon non-voting units as of the date of theSpin-Out. Ikaria had granted RSUs to employees that generally vested over four years. RSUs granted prior to January 1, 2011 vested 25% annually. RSUsgranted on and after January 1, 2011 vested 25% on the second and third anniversary of the date of grant and 50% on the fourth anniversary of the date ofgrant. Shares of Ikaria non-voting common stock were delivered to the employee upon vesting, subject to payment of applicable withholding taxes, whichwere paid in cash or an equivalent amount of shares withheld. Compensation expense for all RSUs was based on the grant date fair value of the RSU issued,which was based on the fair value of common stock of Ikaria. Compensation expense for RSUs was recognized by Ikaria on a straight-line basis over therequisite service period. The RSU expense allocated from Ikaria totaled $0.2 million for the period from January 1, 2014 through February 11, 2014. Stock-Based Compensation Expense, Net of Estimated ForfeituresThe following table summarizes the stock-based compensation expense for the years ended December 31, 2016, 2015 and 2014. The followingdisclosures include stock-based compensation expense recognized under the 2015 Plan and the 2014 Plan and expenses for dates prior to the Spin-Out thatwere allocated to the Company related to Ikaria share-based awards (in thousands)..

Excluding the sale of R&D tax credits thetax rate for 2016 is zero because the Company expects to generate additional losses and currently has a full valuation allowance. The Company was an LLCas of December 31, 2014 and until February 12, 2015 when it converted to a C corporation. Although, the Company was not subject to income taxes in anyjurisdiction while it was an LLC, one of the Company’s subsidiaries was a C-corporation and subject to state and federal income taxes. This subsidiarygenerated an immaterial operating loss in 2014 and the short year ended February 12, 2015. Accordingly, no provision or benefit for income taxes is reflectedin the Company’s 2014 or 2015 consolidated financial statements.A reconciliation of the statutory federal income tax rate to the Company’s effective tax rate for the years ended December 31, 2016 and 2015 is asfollows: Year EndedDecember 31, 2016 Year EndedDecember 31, 2015U.S. federal statutory rate34.0 % 34.0 %State and local taxes, net of federal tax effect6.6 % 5.8 %Research tax credits13.7 % 15.8 %Valuation allowance(38.9)% (55.1)%Prior year adjustments(13.7)% — %Sale of R&D tax credits(1.8)% — %Expenses associated with common stock warrant liability (a)(1.3)% — %Incentive stock options, non-deductible(0.4)% (0.5)%(1.8)% 0.0 % (a) Represents change in fair value and attributable issuance costsDeferred taxes as of December 31, 2016 and 2015 reflect the tax effects of the differences between the amounts recorded as assets and liabilities forfinancial reporting purposes and the comparable amounts recorded for income tax purposes.

As ofDecember 31, 2016, management believed that it was more likely than not that the deferred tax assets would not be realized, based on future operations,consideration of tax strategies and the reversal of deferred tax liabilities. The valuation allowance is required until the Company has sufficient positiveevidence of taxable income necessary to support realization of its deferred tax assets. A valuation allowance release is recognized as an income tax benefit.As of December 31, 2016, the Company has available net operating loss, or NOL, carry forwards for federal income tax reporting purposes ofapproximately $51.7 million and for state income tax reporting purposes of approximately $66.0 million, which expire at various dates between fiscal 2034and 2036. The Company plans to sell a portion of its state NOLs under the State of New Jersey’s Technology Business Tax Certificate Transfer Program in2017. As of December 31, 2016 and 2015, the Company had no material uncertain tax positions.(11) Net Loss Per Share/Unit Basic net loss per share/unit is calculated by dividing net loss by the weighted average number of shares or units outstanding during the period, asapplicable. Diluted net loss per share/unit is calculated by dividing net loss by the weighted average number of shares/units outstanding, adjusted to reflectpotentially dilutive securities (options) using the treasury stock method, except when the effect would be anti-dilutive.The Company is reporting a net loss for the years ended December 31, 2016, 2015 and 2014, therefore diluted net loss per share/unit is the same asthe basic net loss per share/unit.As of December 31, 2016, the Company had 17,142,858 common stock warrants, 3,277,250 options to purchase shares and 155,846 restricted sharesoutstanding that have been excluded from the computation of diluted weighted average units outstanding, because such securities had an antidilutive impactdue to the loss reported.(12) Related-Party Transactions During the years ended December 31, 2013 and 2014, Ikaria was a related party of the Company. Included below and elsewhere in the financialstatements are transactions and balances that relate to agreements entered into while Ikaria was a related party of the Company. Amendments to thoseagreements entered into during the year ended December 31, 2015 were entered into while the Company was no longer a related party.Separation and Distribution Agreement In connection with the Spin-Out, in February 2014, the Company and Ikaria entered into a separation and distribution agreement which sets forthprovisions relating to the separation of the Company’s business from Ikaria’s other businesses. The separation and distribution agreement described the assetsand liabilities that remained with or were transferred to the Company and those that remained with or were transferred to Ikaria. The separation anddistribution agreement provides for a full and complete release and discharge of all liabilities between Ikaria and the Company, except as expressly set forthin the agreement. The Company and Ikaria each agreed to indemnify, defend and hold harmless the other party and its subsidiaries, and each of theirrespective past and present directors, officers and employees, and each of their respective permitted successors and102assigns, from any and all damages relating to, arising out of or resulting from, among other things, the Company’s business and certain additional specifiedliabilities or Ikaria’s business and certain additional specified liabilities, as applicable. License Agreement In February 2014, the Company entered into a cross-license, technology transfer and regulatory matters agreement with a subsidiary of Ikaria. Pursuantto the terms of the license agreement, Ikaria granted to the Company a fully paid-up, non-royalty-bearing, exclusive license under specified intellectualproperty rights controlled by Ikaria to engage in the development, manufacture and commercialization of nitric oxide, devices to deliver nitric oxide andrelated services for or in connection with out-patient, chronic treatment of patients who have PAH, PH-COPD or PH associated with idiopathic pulmonaryfibrosis, or PH-IPF. Pursuant to the terms of the license agreement, the Company granted Ikaria a fully paid-up, non-royalty-bearing, exclusive license underspecified intellectual property rights that the Company controls to engage in the development, manufacture and commercialization of products and servicesfor or used in connection with the diagnosis, prevention or treatment, whether in- or out-patient, of certain conditions and diseases other than PAH, PH-COPDor PH-IPF and for the use of nitric oxide to treat or prevent conditions that are primarily managed in the hospital.

Rent expense, including direct and allocated expenses for 2014, is calculated on the straight-line basis and amounted to approximately $0.7 million, $0.4million, $0.5 million for the years ended December 31, 2016, 2015 and 2014, respectively.Royalty payments and success-based milestones associated with the Company’s license and supply agreements with Ikaria have not been includedin the above table of contractual obligations as the Company cannot reasonably estimate if or when they will occur.In the course of its normal business operations, the Company also enters into agreements with contract service providers and others to assist in theperformance of its research and development and manufacturing activities. The Company can elect to discontinue the work under these contracts andpurchase orders at any time with notice, and such contracts and purchase orders do not contain minimum purchase obligations.

The Company does not intend to proceed with furtherclinical development of BCM until and unless it can determine an alternative path forward. Consequently, any future milestone and royalty payments toBioLine would depend on finding a path forward for future clinical development.(14) Quarterly Financial Data (unaudited) Three Months EndedDecember 31, Three Months EndedSeptember 30, Three Months EndedJune 30, Three Months EndedMarch 31,(in thousands, except share/ and per share data) 2016 2015 2016 2015 2016 2015 2016 2015 Operating expenses: Research and development $5,111 $8,329 $2,472 $7,090 $3,954 $8,426 $5,113 $9,520General and administrative 2,181 2,533 1,745 4,329 1,205 3,435 1,976 4,573Total operating expenses 7,292 10,862 4,217 11,419 5,159 11,861 7,089 14,093Other operating income — — — 250 — 251 — 1,166Loss from operations (7,292) (10,862) (4,217) (11,169) (5,159) (11,610) (7,089) (12,927)Change in fair value of common stock warrantliability (590) — — — — — — —Interest and other income 21 36 22 27 22 27 30 19Pre-tax loss (7,861) (10,826) (4,195) (11,142) (5,137) (11,583) (7,059) (12,908)Income tax benefit (438) — — — — — — —Net loss $(7,423) $(10,826) $(4,195) $(11,142) $(5,137) $(11,583) $(7,059) $(12,908)Weighted average shares outstanding: Basic and diluted 20,186,996 13,026,816 13,854,188 12,911,905 13,093,176 12,910,975 13,053,007 10,152,487Net loss per share: Basic and diluted $(0.37) $(0.83) $(0.30) $(0.86) $(0.39) $(0.90) $(0.54) $(1.27)Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure None. 105Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of ourdisclosure controls and procedures as of December 31, 2016. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by acompany in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified inthe SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that informationrequired to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’smanagement, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timelydecisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provideonly reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship ofpossible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2016, our principal executive officerand principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level. Management’s Annual Report on Internal Control Over Financial Reporting Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended, as aprocess designed by, or under the supervision of, the company’s principal executive and principal financial officers and effected by the company’s board ofdirectors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financialstatements for external purposes in accordance with generally accepted accounting principles. The company’s internal control over financial reportingincludes 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 thecompany;•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generallyaccepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations ofmanagement 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 thatcould have a material effect on the financial statements.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluationof effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree ofcompliance with the policies or procedures may deteriorate.The company’s management assessed the effectiveness of the company’s internal control over financial reporting as of December 31, 2016. Inmaking this assessment, management used the criteria set forth in the Internal Control - Integrated Framework (2013) issued by the Committee of SponsoringOrganizations of the Treadway Commission (COSO).Based on our assessment, management believes that, as of December 31, 2016, the company’s internal control over financial reporting is effectivebased on those criteria. Changes in Internal Control Over Financial Reporting No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during thefiscal quarter ended December 31, 2016 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
