You should carefully consider all of the information set forth in this annual report and in our other filings with theUnited States Securities and Exchange Commission, or the SEC, including the following risk factors which we face, and which are faced by our industry.Our business, financial condition or results of operations could be materially adversely affected by any of these risks. This report also contains forward-looking statements that involve risks and uncertainties. Our results could materially differ from those anticipated in these forward-looking statements, as aresult of certain factors including the risks described below and elsewhere in this annual report and our other SEC filings. See “Special Note RegardingForward-Looking Statements” above.Risks Related to Our Limited Operating History, Financial Condition and Capital RequirementsWe have a limited operating history and have incurred significant losses and negative cash flows since our inception, and we anticipate that we willcontinue to incur significant losses and negative cash flows for the foreseeable future, which makes it difficult to assess our future viability.We are a clinical stage biopharmaceutical company with a limited operating history upon which you can evaluate our business and prospects. We are notprofitable and have incurred net losses in each period since we commenced operations in 2004, including net losses of $20.0 million and $1.9 million for theyears ended December 31, 2017 and 2016, respectively. We expect to continue to incur significant expenses and increasing operating losses for theforeseeable future. Our ability to ultimately achieve recurring revenues and profitability is dependent upon our ability to successfully complete thedevelopment of our product candidates and obtain necessary regulatory approvals for and successfully manufacture, market and commercialize our products.We believe that we will continue to expend substantial resources in the foreseeable future for the clinical development of our current product candidates orany additional product candidates and indications that we may choose to pursue in the future. These expenditures will include costs associated with researchand development, conducting preclinical studies and clinical trials, and payments for third-party manufacturing and supply, as well as sales and marketing ofany of our product candidates that are approved for sale by regulatory agencies. Because the outcome of any clinical trial is highly uncertain, we cannotreasonably estimate the actual amounts necessary to successfully complete the development and commercialization of our clinical stage and preclinical drugcandidates and any other drug candidates that we may develop in the future. Other unanticipated costs may also arise.Our future capital requirements depend on many factors, including: •the timing of, and the costs involved in, clinical development and obtaining regulatory approvals for our product candidates; •changes in regulatory requirements during the development phase that can delay or force us to stop our activities related to any of our productcandidates; •the cost of commercialization activities if our products are approved for sale, including marketing, sales and distribution costs; •the cost of third-party manufacturing of our products; •the number and characteristics of any other product candidates we develop or acquire; •our ability to establish and maintain strategic collaborations, licensing or other commercialization arrangements, and the terms and timing of sucharrangements; •the extent and rate of market acceptance of any approved products; •the expenses needed to attract and retain skilled personnel; •the costs associated with being a public company; •the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent and other intellectual property claims, includingpotential litigation costs, and the outcome of such litigation; •the timing, receipt and amount of sales of, or royalties on, future approved products, if any; •any product liability or other lawsuits related to our products;4 •scientific breakthroughs in the field of urothelial cancer treatment and diagnosis that could significantly diminish the need for our productcandidates or make them obsolete; and •changes in reimbursement policies that could have a negative impact on our future revenue stream.In addition, we have limited experience and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequentlyencountered by companies in new and rapidly evolving fields, particularly in the biopharmaceutical industry. Drug development is a highly speculativeundertaking and involves a substantial degree of risk. To date, we have not obtained any regulatory approvals for any of our product candidates,commercialized any of our product candidates or generated any material revenue from product sales.We will require substantial additional financing to achieve our goals, and a failure to obtain this capital when needed and on acceptable terms, or at all,could force us to delay, limit, reduce or terminate our product development, commercialization efforts or other operations.Since our inception, almost all our resources have been dedicated to the preclinical and clinical development of our lead product candidates, MitoGel andVesiGel. As of December 31, 2017, we had cash and cash equivalents of $37 million and short-term investments of $36 million, for aggregate cash, cashequivalents and short-term investments of $73.0 million.In January 2018, we completed a secondary public offering on the Nasdaq Stock Market of 1,682,926 ordinary shares, at a public offering price of $41.00 pershare, in consideration for approximately $64 million net of underwriting discounts and commissions and issuance costs, including exercise of theunderwriters’ option to purchase an additional 219,512 ordinary shares at the public offering price.We believe we have sufficient cash, cash equivalents and short-term investments to fund our operating expenses and capital expenditure requirements for atleast the next 12 months. We expect that we will require additional capital to complete clinical trials, obtain regulatory approval for and commercialize ourproduct candidates. However, our operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional fundssooner than planned, through public or private equity, convertible debt or debt financings, third-party funding, marketing and distribution arrangements, aswell as other collaborations, strategic alliances and licensing arrangements, or a combination of these approaches. In any event, we will require additionalcapital to pursue preclinical and clinical activities, and pursue regulatory approval for, and to commercialize, our pipeline product candidates. Even if webelieve that we have sufficient funds for our current or future operating plans, we may seek additional capital if market conditions are favorable or if we havespecific strategic considerations.Any additional fundraising efforts may divert the attention of our management from day-to-day activities, which may adversely affect our ability to developand commercialize our product candidates. In addition, we cannot guarantee that future financing will be available in sufficient amounts or on termsacceptable to us, if at all. Moreover, the terms of any financing may negatively impact the holdings or the rights of our shareholders, and the issuance ofadditional securities, whether equity or debt, by us or the possibility of such issuance may cause the market price of our shares to decline. The incurrence ofindebtedness could result in increased fixed payment obligations and we may be required to agree to certain restrictive covenants, such as limitations on ourability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that couldadversely impact our ability to conduct our business. We could also be required to seek funds through arrangements with collaborative partners or otherwiseat an earlier stage than would be desirable and we may be required to relinquish rights to some of our technologies, intellectual property or productcandidates or otherwise agree to terms unfavorable to us, any of which may harm our business, financial condition, cash flows, operating results andprospects.If adequate funds are not available to us on a timely basis, we may be required or choose to: •delay, limit, reduce or terminate preclinical studies, clinical trials or other development activities for our product candidates or any of our futureproduct candidates; •delay, limit, reduce or terminate our other research and development activities; or •delay, limit, reduce or terminate our establishment or expansion of manufacturing, sales and marketing or distribution capabilities or otheractivities that may be necessary to commercialize MitoGel, VesiGel or any of our other product candidates.We may also be unable to expand our operations or otherwise capitalize on our business opportunities, as desired, which could harm our business, financialcondition, cash flows and results of operations.5 Raising additional capital may cause dilution to our shareholders, restrict our operations or require us to relinquish rights to our technologies or productcandidates.Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through equity, convertible debt or debtfinancings, as well as selectively continuing to enter into collaborations, strategic alliances and licensing arrangements. We do not currently have anycommitted external source of funds other than funding under the existing exclusive license agreement we entered into with Allergan PharmaceuticalsInternational Limited, or Allergan, a wholly owned subsidiary of Allergan plc, in October 2016, or the Allergan Agreement. Under the Allergan Agreement,we may receive additional material milestone payments upon the successful completion of certain development, regulatory and commercial milestones androyalties with respect to future sales of collaboration products by Allergan. Allergan may unilaterally terminate our existing collaboration for any reasonupon advance notice. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will bediluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as an ordinary shareholder. Debtfinancing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additionaldebt, making capital expenditures or declaring and distributing dividends, and may be secured by all or a portion of our assets.If we raise funds by selectively continuing to enter into additional collaborations, strategic alliances or licensing arrangements with third parties, we mayhave to relinquish additional valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses onterms that may not be favorable to us. If we are unable to raise additional funds through equity, convertible debt 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 additional funds through other collaborations, strategicalliances or licensing arrangements, we may be required to terminate product development or future commercialization efforts or to cease operationsaltogether.Risks Related to Our Business and StrategyWe are dependent on the success of our lead product candidates, including obtaining regulatory approval to market our product candidates in the UnitedStates.We have invested almost all our efforts and financial resources in the research and development of our lead product candidates, MitoGel and VesiGel. Ourfuture success depends on our ability to market and sell these product candidates. However, these drugs are in various stages of clinical development andeach of these drugs has yet to receive marketing approval from the U.S. Food and Drug Administration, or the FDA, or any other regulatory agency. Ourproduct candidates’ marketability is subject to significant risks associated with successfully completing current and future clinical trials, including: •the FDA’s timely acceptance of our investigational new drug, or IND, filing for VesiGel, which we intend to submit in the first half of 2018, and ourother product candidates for which we plan to file an IND. Without such IND acceptances, we will be unable to commence clinical trials in theUnited States; •the FDA’s acceptance of our parameters for regulatory approval relating to MitoGel, VesiGel and our other product candidates, including ourproposed indications, primary and secondary endpoint assessments and measurements, safety evaluations and regulatory pathways; •the FDA’s acceptance of the number, design, size, conduct and implementation of our clinical trials, our trial protocols and the interpretation ofdata from preclinical studies or clinical trials; •our ability to successfully complete the clinical trials of our product candidates, including timely patient enrollment and acceptable safety andefficacy data and our ability to demonstrate the safety and efficacy of the product candidates undergoing such clinical trials; •the FDA’s timely acceptance of our NDA for MitoGel, following our expected submission in the first quarter of 2019, and our eligibility for priorityreview of our NDA submission by the FDA; •our ability to complete in a timely fashion the single pivotal Phase 3 clinical trial for MitoGel for the treatment of low-grade upper tract urothelialcarcinoma, or UTUC, and that the single pivotal Phase 3 clinical trial, even if successfully completed, will be sufficient to support a New DrugApplication, or NDA, submission and subsequently, FDA approval; •our ability to successfully complete the FDA requirements related to chemistry, manufacturing and control (CMC) for our MitoGel, VesiGel andour other product candidates, and if completed, will it be sufficient to support a New Drug Application, or NDA;6 •the FDA’s acceptance of the sufficiency of the data we collected from our preclinical studies and our Phase 2a clinical trial with VesiGel in low-grade non-muscle invasive bladder cancer, or NMIBC, and expect to collect from toxicological studies that we may conduct to support thesubmission of an IND without requiring additional preclinical studies or clinical trials, and our ability to commence a Phase 2b clinical trial in theUnited States for VesiGel in low-grade NMIBC following an IND application, if accepted; •the FDA’s need to schedule an advisory committee meeting, and to conduct such meeting, in a timely manner to evaluate and decide on theapproval of our potential future NDAs for MitoGel and VesiGel; •the recommendation of the FDA’s advisory committee to approve our applications to market MitoGel and VesiGel and our other productcandidates in the United States, without limiting the approved labeling, specifications, distribution or use of the products, or imposing otherrestrictions; •the FDA’s satisfaction with the safety and efficacy of our product candidates; •the prevalence and severity of adverse events associated with our product candidates as there were no drugs and related drug administrationprocedures approved for LG UTUC or LG NMIBC that are based on RTGel technology; •the timely and satisfactory performance by third-party contractors of their obligations in relation to our clinical trials; •our success in educating physicians and patients about the benefits, administration and use of our product candidates, if approved, particularly inlight of the fact that there are currently no drugs approved by the FDA for the treatment of UTUC and the FDA has not approved a drug for thetreatment of NMIBC in more than 15 years; •the availability, perceived advantages, relative cost, safety and efficacy of alternative and competing treatments for the indications addressed byour product candidates; •the effectiveness of our marketing, sales and distribution strategy, and operations, as well as that of any current and future licensees; •our ability to develop, validate and maintain a commercially viable manufacturing process that is compliant with current good manufacturingpractices, or cGMP; •our ability to secure supply of the raw materials from TAPI (Teva Active Pharmaceutical Ingredients) or other suppliers for our product candidatesto support the clinical trial and commercial use; •our ability to obtain, protect and enforce our intellectual property rights with respect to our product candidates; and •our ability to properly train physicians or nurses for the skillful administration of our products, including MitoGel and VesiGel, and our ability todevelop a broad experiential knowledge base of aggregated clinician feedback from which we can refine appropriate procedures for productadministration, without which there could be a risk of adverse events.Many of these clinical, regulatory and commercial risks are beyond our control. Accordingly, we cannot assure you that we will be able to advance any of ourproduct candidates through clinical development, or to obtain regulatory approval of or commercialize any of our product candidates. If we fail to achievethese objectives or overcome the challenges presented above, we could experience significant delays or an inability to successfully commercialize ourproduct candidates. Accordingly, we may not be able to generate sufficient revenues through the sale of our product candidates to enable us to continue ourbusiness.We may be unable to obtain regulatory approval for our product candidates.The research, development, testing, manufacturing, labeling, packaging, approval, promotion, advertising, storage, recordkeeping, marketing, distribution,post-approval monitoring and reporting, and export and import of drug products are subject to extensive regulation by the FDA, and by foreign regulatoryauthorities in other countries. These regulations differ from country to country. To gain approval to market our product candidates, we must provide clinicaldata that adequately demonstrate the safety and efficacy of the product for the intended indication. We have not yet obtained regulatory approval to marketany of our product candidates in the United States or any other country. Our business depends upon obtaining these regulatory approvals. There are currentlyno drugs approved by the FDA for the treatment of UTUC and only three drugs have been approved by the FDA for NMIBC, with the last approval havingoccurred over 15 years ago. The FDA can delay, limit or deny approval of our product candidates for many reasons, including: •our inability to satisfactorily demonstrate that the product candidates are safe and effective for the target indication; •the FDA’s disagreement with our trial protocol, the interpretation of data from preclinical studies or clinical trials or conduct and control of clinicaltrials;7 •the patient population studied in the clinical trial may not be sufficiently large, broad or representative to assess efficacy and safety in the patientpopulation for which we seek approval; •our inability to demonstrate that clinical or other benefits of our product candidates outweigh any safety or other perceived risks; •the FDA’s determination that the 505(b)(2) regulatory pathway is not available for our product candidates; •the FDA’s determination that additional preclinical studies or clinical trials are required; •the FDA’s determination that the Fast Track Designation, or FTD, for MitoGel is no longer accepted or our trial results do not meet the criteria forFTD; •the FDA’s determination that the Orphan Drug Designation, or ODD, for MMC for UTUC is no longer accepted; •the FDA’s determination that the quality of our drug substance or drug product, formulation, labeling or the specifications of our productcandidates is insufficient for approval; •the FDA’s failure to accept the manufacturing processes or facilities of third-party manufacturers with which we contract; •the potential for approval policies or regulations of the FDA to significantly change in a manner rendering our clinical data insufficient forapproval; or •resistance to approval from the FDA’s advisory committee for any reason including safety or efficacy concerns.Even if we eventually complete clinical testing and receive approval of any regulatory filing for our product candidates, the FDA may grant approvalcontingent on the performance of costly and potentially time-consuming additional post-approval clinical trials or subject to restrictive Risk Evaluation andMitigation Strategies. The FDA may also approve our product candidates for a more limited indication or a narrower patient population than we originallyrequested, and the FDA may not approve the labeling that we believe is necessary or desirable for the successful commercialization of our product candidates.To the extent we seek regulatory approval in foreign countries, we may face challenges similar to those described above with regulatory authorities inapplicable jurisdictions. Any delay in obtaining, or inability to obtain, applicable regulatory approval for any of our product candidates would delay orprevent commercialization of our product candidates and would thus negatively impact our business, results of operations and prospects.To date, we have only generated limited clinical data for our product candidates.Positive results in preclinical testing and early clinical trials do not ensure that later clinical trials will be successful. A number of pharmaceutical companieshave suffered significant setbacks in clinical trials, including in Phase 3 clinical trials, after promising results in preclinical testing and early clinical trials.These setbacks have included negative safety and efficacy observations in later clinical trials, including previously unreported adverse effects. For example,we enrolled only 22 patients into the recently completed UTUC Compassionate Use program of MitoGel. In the Compassionate Use Program, of the 18patients confirmed with low-grade UTUC disease, only 13 patients had completed the six-weekly administration treatment regimen were evaluated forresponse, and eight of the 13 patients achieved a complete response and the remaining five achieved a partial response at the primary evaluation time. Of theeight patients who achieved a complete response at the primary evaluation time, three have subsequently experienced recurrences to date. The data generatedby our Compassionate Use program may not be as reliable as data generated from a clinical trial. For instance, consistent with the nature of CompassionateUse programs, our Compassionate Use program is investigator-initiated and driven, with no uniform protocol with respect to dosing, primary endpoint orfrequency or timing of follow-up evaluations. The data collected in our Compassionate Use program is based on individual physician reports and has notundergone independent monitoring or quality assurance. The follow-up evaluation plan for patients is determined by each individual investigator and variesfrom patient to patient, and some patients have not undergone follow-up evaluation or have been lost to follow-up. Due to the intricate anatomy of the renalpelvis and the calyceal system, we also face the risk that MitoGel may not reach all tumors. To date in our preclinical testing, Compassionate Use programand clinical trials, we have observed several adverse events and serious adverse events, consisting primarily of burning sensation, rash, flank pain, kidneyswelling, kidney infection, urgency in urination and pain during urination. In addition, we have observed transient perturbation of laboratory measures ofrenal and hematopoietic function as well as renal stricture and stenosis. No study participants have required medical intervention to address these changes.These adverse events are known MMC, or procedure-related adverse events and many are indicated as potential side effects of MMC usage on the MMClabel. However, we cannot assure you that adverse events related to MitoGel and VesiGel that are not directly attributable to MMC specifically will notoccur. In addition, this trial may not be successful. If our clinical trials do not ultimately indicate that our product candidates are safe and efficacious for theirintended application, the FDA may not approve any NDA that we may file to market such product candidates, and our business would not be able to generaterevenue from the sale of any such product candidates.8 We have limited experience in conducting clinical trials and have never obtained approval for any product candidates and may be unable to do sosuccessfully.As a company, we have limited experience in conducting clinical trials and have never progressed a product candidate through to regulatory approval. In partbecause of this lack of experience, our clinical trials may require more time and incur greater costs than we anticipate. We cannot be certain that the plannedclinical trials will begin or conclude on time, if at all. Large-scale trials will require significant additional financial and management resources. In addition,due to the significant lack of drug development for non-muscle invasive urothelial cancers over the past 15 years, neither we nor any third-party clinicalinvestigators, clinical research organizations, or CROs, and/or consultants are likely to have extensive experience conducting clinical trials for theindications we are targeting. Third-party clinical investigators do not operate under our control. Any performance failure on the part of such third partiescould delay the clinical development of our product candidates or delay or prevent us from obtaining regulatory approval or commercializing our current orfuture product candidates, depriving us of potential product revenue and resulting in additional losses.We have not applied for regulatory approvals to market any of our product candidates, and we may be delayed in obtaining or failing to obtain suchregulatory approvals and to commercialize our product candidates.The process of developing, obtaining regulatory approval for and commercializing our product candidates is long, complex, costly and uncertain, and delaysor failure can occur at any stage. The research, testing, manufacturing, labeling, marketing, sale and distribution of drugs are subject to extensive and rigorousregulation by the FDA and foreign regulatory agencies, as applicable. These regulations are agency-specific and differ by jurisdiction. We are not permittedto market any product candidate in the United States until we receive approval of an NDA from the FDA, or in any foreign countries until we receive therequisite approval from the respective regulatory agencies in such countries. To gain approval of an NDA or other equivalent regulatory approval, we mustprovide the FDA or relevant foreign regulatory authority with preclinical and clinical data that demonstrates the safety and efficacy of the product for theintended indication.Before we can submit an NDA to the FDA or comparable similar applications to foreign regulatory authorities, we must conduct Phase 3 clinical trials, or apivotal/registration trial equivalent, for each product candidate. We commenced a single pivotal, open-label, single-arm Phase 3 clinical trial of MitoGel forthe treatment of low-grade UTUC in the first quarter of 2017. This clinical trial is substantially broader than the previous Compassionate Use program forMitoGel for the treatment of patients with UTUC and requires us to enroll a considerably larger number of patients in multiple clinics and medical centersacross multiple countries. Based on our discussions with the FDA, our current expectation is that our pivotal clinical trial for MitoGel will evaluateapproximately 74 patients. We cannot assure you that we will be able to complete patient enrollment, generate top-line and final data or submit the NDA forMitoGel in timely fashion. Moreover, we are also planning to commence a Phase 2b clinical trial of VesiGel in 2018. Before commencing a clinical trial forVesiGel in the United States, we must first file an IND, which must be cleared by the FDA. We cannot assure you that the FDA will not decide to materiallyalter these parameters, including potentially requiring a pivotal study with a control arm, during the trial or require us to conduct more than one pivotal trialbefore submitting an NDA.Phase 3 clinical trials often produce unsatisfactory results even though prior clinical trials were successful. Moreover, the results of clinical trials may beunsatisfactory to the FDA or foreign regulatory authorities even if we believe those clinical trials to be successful. The FDA or applicable foreign regulatoryagencies may suspend one or all of our clinical trials or require that we conduct additional clinical, preclinical, manufacturing, validation or drug productquality studies and submit that data before considering or reconsidering any NDA or comparable foreign regulatory application that we may submit.Depending on the extent of these additional studies, approval of any applications that we submit may be significantly delayed or may cause the terminationof such programs or may require us to expend more resources than we have available.If any of these outcomes occur, we may not receive regulatory approval for the corresponding product candidates, and our business would not be able togenerate revenue from the sale of any such product candidates.We may not be able to advance our preclinical product candidates into clinical development and through regulatory approval and commercialization.Certain of our product candidates are currently in preclinical development and are therefore currently subject to the risks associated with preclinicaldevelopment, including the risks associated with: •generating adequate and sufficient preclinical safety and efficacy data in a timely fashion to support the initiation of clinical trials; •obtaining regulatory approval to commence clinical trials in any jurisdiction, including the submission and acceptance of INDs;9 •contracting with the necessary parties to conduct a clinical trial; •enrolling sufficient numbers of patients in clinical trials in timely fashion, if at all; and •timely manufacture of sufficient quantities of the product candidate for use in clinical trials.If we are unsuccessful in advancing our preclinical product candidates into clinical trials in a timely fashion, our business may be harmed. Even if we aresuccessful in advancing our preclinical product candidates into clinical development, their success will be subject to all of the clinical, regulatory andcommercial risks described elsewhere in “Risk Factors.” Accordingly, we cannot assure you that we will be able to develop, obtain regulatory approval for,commercialize or generate significant revenue from our product candidates.Clinical drug development involves a lengthy and expensive process with an uncertain outcome, results of earlier studies and trials may not be predictiveof future trial results, and our clinical trials may fail to adequately demonstrate the safety and efficacy of our product candidates.Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. A failure of one or more of our clinical trials canoccur at any time during the clinical trial process. We do not know whether our ongoing and future clinical trials, if any, will begin on time, need to beredesigned, enroll an adequate number of patients on time or be completed on schedule, if at all. Clinical trials can be delayed, suspended or terminated for avariety of reasons, including failure to: •generate sufficient preclinical, toxicology, or other in vivo or in vitro data to support the initiation or continuation of clinical trials; •obtain regulatory approval, or feedback on trial design, in order to commence a trial; •identify, recruit and train suitable clinical investigators; •reach agreement on acceptable terms with prospective CROs and clinical trial sites, and have such CROs and sites effect the proper and timelyconduct of our clinical trials; •obtain and maintain institutional review board, or IRB, approval at each clinical trial site; •identify, recruit and enroll suitable patients to participate in a trial; •have a sufficient number of patients enrolled, complete a trial or return for post-treatment follow-up; •ensure clinical investigators and clinical trial sites observe trial protocol or continue to participate in a trial; •address any patient safety concerns that arise during the course of a trial; •address any conflicts with new or existing laws or regulations; •add a sufficient number of clinical trial sites; •manufacture sufficient quantities at the required quality of product candidate for use in clinical trials; or •raise sufficient capital to fund a trial.Patient enrollment is a significant factor in the timing and success of clinical trials and is affected by many factors, including the size and nature of thepatient population, the proximity of patients to clinical sites, the eligibility criteria for the trial, the design of the clinical trial, competing clinical trials andclinicians’ and patients’ or caregivers’ perceptions as to the potential advantages of the drug candidate being studied in relation to other available therapies,including any new drugs or treatments that may be developed or approved for the indications we are investigating.We may also encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions in which such trials are being conducted, bythe trial’s data safety monitoring board, by the FDA or by the applicable foreign regulatory authorities. Such authorities may suspend or terminate one ormore of our clinical trials due to a number of factors, including our failure to conduct the clinical trial in accordance with relevant regulatory requirements orclinical protocols, inspection of the clinical trial operations or trial site by the FDA or foreign regulatory authorities resulting in the imposition of a clinicalhold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations oradministrative actions or lack of adequate funding to continue the clinical trial.If we experience delays in carrying out or completing any clinical trial of our product candidates, the commercial prospects of our product candidates may beharmed, and our ability to generate product revenues from any of these product candidates will be delayed.10 In addition, any delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval process andjeopardize our ability to commence product sales and generate revenues. Any of these occurrences may significantly harm our business and financialcondition. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to thedenial of regulatory approval of our product candidates.The market opportunities for our product candidates may be limited to those patients who are ineligible for established therapies or for whom priortherapies have failed and may be small.Cancer therapies are sometimes characterized as first-line, second-line or third-line. When cancer is detected early enough, first-line therapy, oftenchemotherapy, hormone therapy, surgery, radiotherapy or a combination of these, is sometimes adequate to cure the cancer or prolong life. Second- and third-line therapies are administered to patients when prior therapy is not or is no longer effective. For urothelial cancers, the current first-line standard of care issurgery designed to remove one or more tumors. Chemotherapy is currently used in treating urothelial cancer only as an adjuvant, or supplemental therapy,after tumor resection. We are designing our lead product candidates with the goal of replacing surgery as the first-line standard of care for certain urothelialcancers. We intend to seek approval of MitoGel for the first-line treatment of low-grade UTUC and of VesiGel for the first-line treatment of low-grade NMIBCin both cases as a chemoablation agent to replace tumor resection surgeries. However, there is no guarantee that our product candidates, if approved, wouldbe approved for first-line or even later lines of therapy, and, that prior to any such approvals, we will not have to conduct additional clinical trials.Our projections of both the number of people who have the cancers we are targeting, as well as the subset of people with these cancers who have previouslyfailed prior treatments, and who have the potential to benefit from treatment with our product candidates, are based on our beliefs and estimates. Theseestimates have been derived from a variety of sources, including scientific literature, surveys of clinics, patient foundations or third-party market research,and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these cancers and the number of patients may turnout to be lower than expected. Additionally, the potentially addressable patient population for our product candidates may be limited or may not beamenable to treatment with our product candidates. Even if we receive regulatory approval for our product candidates and obtain significant market share,because the potential target populations are small, we may never achieve profitability without obtaining regulatory approval for additional indications,including the use of the products as first- or second-line therapy.MitoGel or VesiGel or any of our other product candidates may produce undesirable side effects that we may not have detected in our previous preclinicalstudies and clinical trials or that are not expected with MMC treatment or inconsistent with catheter administration procedures. This could prevent usfrom gaining marketing approval or market acceptance for these product candidates, or from maintaining such approval and acceptance, and couldsubstantially increase commercialization costs and even force us to cease operations.As with most pharmaceutical products, use of MitoGel or VesiGel or our other product candidates may be associated with side effects or adverse events thatcan vary in severity and frequency. Our proprietary reverse thermal gelation hydrogel, or RTGel, which is used in the formulation of MitoGel and VesiGel,has not undergone extensive testing in humans. Side effects or adverse events associated with the use of MitoGel and VesiGel may be observed at any time,including in clinical trials or once a product is commercialized, and any such side effects or adverse events may negatively affect our ability to obtainregulatory approval or market our product candidates. To date in our clinical trials, we have observed several adverse events and serious adverse events,consisting primarily of burning sensation, rash, flank pain, kidney swelling, kidney infection, urgency in urination and pain during urination. In addition, wehave observed transient perturbation of laboratory measures of renal and hematopoietic function as well as renal stricture and stenosis. These adverse eventsare known MMC, or procedure-related adverse events and many are indicated as potential side effects of MMC usage on the MMC label. However, we cannotassure you that we will not observe additional drug or procedure-related serious adverse events in the future or that the FDA will not determine them as such.Side effects such as toxicity or other safety issues associated with the use of our product candidates could require us to perform additional studies or haltdevelopment or sale of these product candidates or expose us to product liability lawsuits, which will harm our business.Furthermore, the commenced single pivotal Phase 3 clinical trial for MitoGel and the planned Phase 2b clinical trial for VesiGel will involve a larger patientbase than that previously studied, and the commercial marketing of MitoGel and VesiGel, if approved, will further expand the clinical exposure of the drugsto a wider and more diverse group of patients than those participating in the clinical trials, which may identify undesirable side effects caused by theseproducts that were not previously observed or reported.The FDA and foreign regulatory agency regulations require that we report certain information about adverse medical events if our products may have causedor contributed to those adverse events. The timing of our obligation to report would be triggered by the date upon which we become aware of the adverseevent as well as the nature and severity of the event. We may fail to report adverse events of which we become aware within the prescribed timeframe. We mayalso fail to appreciate that we have become aware of a reportable adverse event, especially if it is not reported to us as an adverse event or if it is an adverseevent that is unexpected or11 removed in time from the use of our products. If we fail to comply with our reporting obligations, the FDA or a foreign regulatory agency could take actionincluding enforcing a hold on or cessation of clinical trials, withdrawal of approved drugs from the market, criminal prosecution, the imposition of civilmonetary penalties or seizure of our products.Additionally, in the event we discover the existence of adverse medical events or side effects caused by one of our product candidates, a number of otherpotentially significant negative consequences could result, including: •our inability to submit an NDA or similar application for our product candidates because of insufficient risk-reward, or the denial of suchapplication by the FDA or foreign regulatory authorities; •the FDA or foreign regulatory authorities suspending or terminating our clinical trials or suspending or withdrawing their approval of the product; •the FDA or foreign regulatory authorities requiring the addition of labeling statements, such as Box or other warnings or contraindications ordistribution and use restrictions; •the FDA or foreign regulatory authorities requiring us to issue specific communications to healthcare professionals, such as letters alerting them tonew safety information about our product, changes in dosage or other important information; •the FDA or foreign regulatory authorities issuing negative publicity regarding the affected product, including safety communications; •our being limited with respect to the safety-related claims that we can make in our marketing or promotional materials; •our being required to change the way the product is administered, conduct additional preclinical studies or clinical trials or restrict or cease thedistribution or use of the product; and •our being sued and held liable for harm caused to patients.Any of these events could prevent us from achieving approval or market acceptance of the affected product candidate and could substantially increasecommercialization costs or even force us to cease operations. We cannot assure you that we will resolve any issues related to any product-related adverseevents to the satisfaction of the FDA or any regulatory agency in a timely manner or ever, which could harm our business, prospects and financial condition.Even if our product candidates receive marketing approval, we may continue to face future developmental and regulatory difficulties. In addition, we aresubject to government regulations and we may experience delays in obtaining required regulatory approvals to market our proposed product candidates.Even if we complete clinical testing and receive approval of any regulatory filing for our product candidates, the FDA or applicable foreign regulatoryagency may grant approval contingent on the performance of additional costly post-approval clinical trials, risk mitigation requirements and surveillancerequirements to monitor the safety or efficacy of the product, which could negatively impact us by reducing revenues or increasing expenses, and cause theapproved product candidate not to be commercially viable. Absence of long-term safety data may further limit the approved uses of our products, if any.The FDA or applicable foreign regulatory agency also may approve our product candidates for a more limited indication or a narrower patient populationthan we originally requested or may not approve the labeling that we believe is necessary or desirable for the successful commercialization of our productcandidates. Furthermore, any such approved product will remain subject to extensive regulatory requirements, including requirements relating tomanufacturing, labeling, packaging, adverse event reporting, storage, advertising, promotion, distribution and recordkeeping.If we fail to comply with the regulatory requirements of the FDA or other applicable foreign regulatory authorities, or previously unknown problems with anyapproved commercial products, manufacturers or manufacturing processes are discovered, we could be subject to administrative or judicially imposedsanctions or other setbacks, including the following: •suspension or imposition of restrictions on operations, including costly new manufacturing requirements; •regulatory agency refusal to approve pending applications or supplements to applications; •suspension of any ongoing clinical trials; •suspension or withdrawal of marketing approval; •an injunction or imposition of civil or criminal penalties or monetary fines;12 •seizure or detention of products; •bans or restrictions on imports and exports; •issuance of warning letters or untitled letters; •suspension or imposition of restrictions on operations, including costly new manufacturing requirements; or •refusal of regulatory authorities to approve pending applications or supplements to applications.In addition, various aspects of our operations are subject to federal, state or local laws, rules and regulations, any of which may change from time to time.Costs arising out of any regulatory developments could be time-consuming and expensive and could divert management resources and attention and,consequently, could adversely affect our business, financial condition, cash flows and results of operations.Even if our product candidates receive regulatory approval, they may fail to achieve the broad degree of physician adoption and use and marketacceptance necessary for commercial success.Even if we obtain FDA or foreign regulatory approvals for our product candidates, the commercial success of such products will depend significantly on theirbroad adoption and use by physicians, for approved indications, including, in the case of MitoGel, for the first-line treatment of low-grade UTUC, and in thecase of VesiGel, for the first-line treatment of low-grade NMIBC, and for other therapeutic indications that we may seek to pursue with any of our productcandidates. Physicians treating low-grade UTUC and low-grade NMIBC have never had to consider first-line treatments other than surgery. The degree andrate of physician and patient adoption of our product candidates, if approved, will depend on a number of factors, including: •the clinical indications for which the product is approved; •the prevalence and severity of adverse side effects and the level of risk/reward observed in our clinical trials; •patient satisfaction with the results and administration of our product and overall treatment experience, including relative convenience, ease of useand avoidance of, or reduction in, adverse side effects; •the extent to which physicians recommend our products to patients; •physicians’ and patients’ willingness to adopt new therapies in lieu of other products or treatments, including willingness to adopt our leadproduct candidates as locally-administered drug replacements to current surgical standards of care; •the cost of treatment, safety and efficacy in relation to alternative treatments, including the recurrence rate of our treatments; •the extent to which the costs of our product candidates are reimbursed by third-party payors, and patients’ willingness to pay for our products; •whether treatment with our product candidates, including the treatment of low-grade UTUC with MitoGel and the treatment of low-grade NMIBCwith VesiGel, will be deemed to be an elective procedure by third- party payors; if so, the cost of treatment would be borne by the patient andwould be less likely to be broadly adopted; •proper training of physicians or nurses for the skillful administration of our products, including MitoGel and VesiGel, and development of a broadexperiential knowledge base of aggregated clinician feedback from which we can refine appropriate procedures for product administration, withoutwhich there could be a risk of adverse events; •the revenues and profitability that our products will offer physicians as compared to alternative therapies; and •the effectiveness of our sales and marketing efforts, especially the success of any targeted marketing efforts directed toward physicians and clinicsand any direct-to-consumer marketing efforts we may initiate.If MitoGel, VesiGel or any of our other product candidates is approved for use but fails to achieve the broad degree of physician adoption and marketacceptance necessary for commercial success, our operating results and financial condition would be adversely affected.If we are not successful in developing, receiving regulatory approval for and commercializing our preclinical and clinical product candidates other thanMitoGel or VesiGel, our ability to expand our business and achieve our strategic objectives could be impaired.Although we will devote a substantial portion of our resources to the continued clinical testing and potential approval of MitoGel for the treatment of low-grade UTUC and VesiGel for the treatment of low-grade NMIBC, another key element of our strategy is to discover, develop and commercialize a portfolio ofproducts based on our proprietary RTGel platforms to serve additional therapeutic markets. We are seeking to do so through our internal research programs,but our resources are limited, and those that we have are geared towards clinical testing and seeking regulatory approval of MitoGel, VesiGel and our otherexisting product candidates. We13 may also explore strategic collaborations for the development or acquisition of new products, but we may not be successful in entering into suchrelationships. While we have commenced a single pivotal Phase 3 clinical trial for MitoGel and plan to commence a Phase 2b clinical trial for VesiGel, all ofour other potential product candidates remain in the preclinical and/or early clinical stages of development. Research programs to identify productcandidates require substantial technical, financial and human resources, regardless of whether any product candidates are ultimately identified. Our researchprograms may initially show promise in identifying potential product candidates, yet fail to yield product candidates for clinical development for manyreasons, including: •the research methodology used may not be successful in identifying potential product candidates; •competitors may develop alternatives that render our product candidates obsolete or less attractive; •a product candidate may in a subsequent trial be shown to have harmful side effects or other characteristics that indicate it is unlikely to beeffective or otherwise does not meet applicable regulatory criteria; •a product candidate may not be capable of being produced in commercial quantities at an acceptable cost, or at all; •a product candidate may not be accepted as safe and effective by patients, the medical community or third-party payors, if applicable; and •intellectual property or other proprietary rights of third parties for product candidates we develop may potentially block our entry into certainmarkets or make such entry economically impracticable.If we fail to develop and successfully commercialize other product candidates, our business and future prospects may be harmed, and our business will bemore vulnerable to any problems that we encounter in developing and commercializing our product candidates.Our product candidates, if approved, will face significant competition with competing technologies and our failure to compete effectively may prevent usfrom achieving significant market penetration.The biopharmaceutical industry is intensely competitive and subject to rapid and significant technological change. Our potential competitors include largeand experienced companies that enjoy significant competitive advantages over us, such as greater financial, research and development, manufacturing,personnel and marketing resources, greater brand recognition and more experience and expertise in obtaining marketing approvals from the FDA and foreignregulatory authorities. These companies may develop new drugs to treat the indications that we target or seek to have existing drugs approved for use for thetreatment of the indications that we target.We are aware that other companies, such as Roche, Vyriad, GSK, Celgene, Lipac Oncology, Samyang biopharma, Merck Sharp & Dohme Corp., Elevenbiotherapeutics, Viralytics Limited, AADi, LLC, Biocancell Ltd., Altor BioScience Corporation, FKD Therapies Oy, Spectrum Pharmaceuticals, Inc., TarisBiomedical LLC and Abnoba, are conducting or have recently conducted clinical trials for product candidates for the treatment of low-grade and high-gradeNMIBC, including carcinoma in situ, or CIS. In addition, we are aware of several pharmaceutical companies that are developing drug candidates for muscle-invasive bladder cancer. The FDA approved 4 immunotherapy drugs known as checkpoint inhibitors; Tecentriq (atezolizumab), Bavenico (Avelumab),Imfinzi (durbalumab) and Keytruda (pembrolizumazb) for the treatment of locally advanced or metastic bladder cancer, a form of muscle invasive bladdercancer. We do not know whether these potential competitors are already developing, or plan to develop, low-grade UTUC or high-grade UTUC treatments orother indications that we are pursuing.Competition may increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for investment inthis industry. Our competitors may succeed in developing, acquiring or licensing on an exclusive basis, products that are more effective, easier to administeror less costly than our product candidates.In addition, we face competition from existing standards of treatment, including transurethral resection of bladder tumor, or TURBT, surgery for bladdercancer. If we are not able to demonstrate that our product candidates are at least as safe and effective as such courses of treatment, medical professionals maynot adopt our product candidates in replacement of the existing standard of care, which is first-line tumor surgical procedures.We have no experience in marketing or distributing products and no internal capability to do so and are therefore subject to certain risks in relation to thecommercialization of our product candidates once approved.We have not yet established a commercial organization for the marketing, sale and distribution of our product candidates. Therefore, even if we receiveapproval to market our product candidates in the United States or other markets, in order to successfully commercialize our product candidates, we will needto either build marketing, sales, distribution, managerial and other non-technical capabilities or contract with third parties to obtain these capabilities. Thisinvolves many challenges, such as recruiting and retaining talented personnel, training employees, setting the appropriate system of incentives, managingadditional headcount and integrating new business units into an14 existing corporate infrastructure. The development of our own sales infrastructure or contracting with third parties will involve substantial expense, much ofwhich we will incur well in advance of any marketing or sales. Moreover, we do not have experience as a company in establishing a significant salesinfrastructure, and we cannot be certain that we will successfully develop this capability or contract successfully with third parties for the necessary services.We will have to compete with other pharmaceutical and biotechnology companies to recruit, hire, train and retain personnel for medical affairs, marketingand sales. If we fail to establish an effective sales and marketing infrastructure or contract with third parties to do so, we will be unable to successfullycommercialize our product candidates, which in turn would have an adverse effect on our business, financial condition and results of operations.We have entered into a licensing agreement and in the future may enter into collaborations with other third parties for the development orcommercialization of our product candidates. If our collaborations are not successful, we may not be able to capitalize on the market potential of theseproduct candidates.In October 2016, we entered into the Allergan Agreement. Under the Allergan Agreement, we granted Allergan an exclusive worldwide license to research,develop, manufacture and commercialize pharmaceutical products that contain RTGel and clostridial toxins (including BOTOX), alone or in combinationwith certain other active ingredients, which we refer to collectively as the Licensed Products. Either party may terminate the Allergan Agreement for uncuredmaterial breach by the other party and for the insolvency of the other party. We may terminate the Allergan Agreement if Allergan or its affiliates challengesany of our patents licensed to Allergan and such patent challenge is not required under a court order or subpoena and is not a defense against a claim, actionor proceeding asserted by us, our affiliates or licensees against Allergan, its affiliates or sublicensees. In addition, Allergan may unilaterally terminate theAllergan Agreement for any reason upon advance notice. If Allergan has the right to terminate the Allergan Agreement due to our uncured material breach,Allergan may elect to continue the agreement and reduce all future milestone and royalty payment obligations to us by a specified percentage. In the event ofany termination of the Allergan Agreement, Allergan will assign or grant a right of reference to any regulatory documentation related to RTGel to us, allrights and licenses to Allergan will terminate, and the license Allergan granted to us under their improvements to RTGel will continue. If any of these eventsoccurs, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for the Licensed Products and will not be able to, or may bedelayed in our efforts to, successfully commercialize the Licensed Products, and our business will be harmed.We may utilize a variety of types of collaboration, distribution and other marketing arrangements with third parties to develop our product candidates andcommercialize our approved product candidates, if any. We are not currently party to any such arrangement. Our ability to generate revenues from thesearrangements will depend on our collaborators’ abilities and efforts to successfully perform the functions assigned to them in these arrangements.Our existing collaboration with Allergan and any future collaborations that we enter into, may pose a number of risks, including the following: •collaborators have significant discretion in determining the amount and timing of efforts and resources that they will apply to these collaborations; •collaborators may not perform their obligations as expected; •product candidates developed by collaborators may not perform sufficiently in clinical trials to be determined to be safe and effective, therebydelaying or terminating the drug approval process and reducing or eliminating milestone payments to which we would otherwise be entitled if theproduct candidates had successfully met their endpoints and/or received FDA approval; •clinical trials conducted by collaborators could give rise to new safety concerns; •clinical trials, such as the ongoing Phase 2 trial being conducted by Allergan for overactive bladder with BotuGel, could fail to meet its efficacyobjectives; •collaborators may not pursue development and commercialization of our product candidates that receive marketing approval or may elect not tocontinue or renew development or commercialization programs based on clinical trial results, changes in the collaborators’ strategic focus oravailable funding, or external factors, such as an acquisition, that divert resources or create 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;15 •product candidates discovered in collaboration with us may be viewed by our collaborators as competitive with their own product candidates orproducts, which may cause collaborators to cease to devote resources to the commercialization of our product candidates; •a collaborator with marketing and distribution rights to one or more of our product candidates that achieve regulatory approval may not commitsufficient resources to the marketing and distribution of such product or products; •disagreements with collaborators, including disagreements over proprietary rights, contract interpretation or the preferred course of development,might cause delays or termination of the research, development or commercialization of product candidates, might lead to additionalresponsibilities for us with respect to product candidates, or might result in litigation or arbitration, any of which would divert managementattention and resources, be time-consuming and expensive; •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; and •collaborations may be terminated for the convenience of the collaborator and, if terminated, we could be required to raise additional capital topursue further development or commercialization of the applicable product candidates.Collaboration agreements may not lead to development or commercialization of product candidates in the most efficient manner, or at all. If the AllerganAgreement, and any future collaborations that we enter into, do not result in the successful development and commercialization of products or if one of ourcollaborators terminates its agreement with us, we may not receive any future research funding or milestone or royalty payments under the collaboration. Ifwe do not receive the funding we expect under these agreements, our development of our product candidates could be delayed, and we may need additionalresources to develop our product candidates. All the risks relating to product development, regulatory approval and commercialization described in thisannual report also apply to the activities of our collaborators.Additionally, subject to its contractual obligations to us, if a collaborator of ours were to be involved in a business combination, it might deemphasize orterminate the development or commercialization of any product candidate licensed to it by us. If one of our collaborators terminates its agreement with us, wemay find it more difficult to attract new collaborators and our perception in the business and financial communities could be harmed.If in the future we acquire or in-license technologies or product candidates, we may incur various costs, may have integration difficulties and mayexperience other risks that could harm our business and results of operations.In the future, we may acquire or in-license additional product candidates and technologies. Any product candidate or technologies we in-license or acquirewill likely require additional development efforts prior to commercial sale, including extensive preclinical or clinical testing, or both, and approval by theFDA and applicable foreign regulatory authorities, if any. All product candidates are prone to risks of failure inherent in pharmaceutical productdevelopment, including the possibility that the product candidate, or product developed based on in-licensed technology, will not be shown to besufficiently safe and effective for approval by regulatory authorities. If intellectual property related to product candidates or technologies we in-license is notadequate, we may not be able to commercialize the affected products even after expending resources on their development. In addition, we may not be able tomanufacture economically or successfully commercialize any product candidate that we develop based on acquired or in-licensed technology that is grantedregulatory approval, and such products may not gain wide acceptance or be competitive in the marketplace. Moreover, integrating any newly acquired or in-licensed product candidates could be expensive and time-consuming. If we cannot effectively manage these aspects of our business strategy, our businessmay be materially harmed.We currently contract with third-party subcontractors and single-source suppliers for certain raw materials, compounds and components necessary toproduce MitoGel, VesiGel and Vesimune for preclinical studies and clinical trials, and expect to continue to do so to support commercial scale productionof MitoGel, VesiGel and Vesimune, if approved. There are significant risks associated with the manufacture of pharmaceutical products and contractingwith contract manufacturers and with single-source suppliers. Furthermore, our existing third-party subcontractors and single-source suppliers may not beable to meet the increased need for certain raw materials, compounds and components that may result from our potential commercialization efforts. Thisincreases the risk that we will not have sufficient quantities of MitoGel, VesiGel or Vesimune or be able to obtain such quantities at an acceptable cost,which could delay, prevent or impair our development or commercialization efforts.We currently rely on third party subcontractors and suppliers for certain compounds and components necessary to produce MitoGel, VesiGel and Vesimunefor our preclinical studies, clinical trials and commercial use, should our drug candidates receive regulatory16 approval. We currently depend on Teva Pharmaceuticals Industries Ltd., or Teva, as our single-source supplier of MMC active pharmaceutical ingredient, orAPI, for MitoGel and VesiGel. Teva is in the midst of a corporate restructuring. Although we are not aware of any impact of the restructuring as currently ineffect on Teva’s ability or willingness to supply us with MMC API in the quantities and on the timeline required, it is possible that the restructuring couldadversely affect our ability to obtain MMC in any given period and could require us to expend funds and effort to identify and engage one or more alternatesuppliers of MMC. We also currently depend on single sources for the gel contained in MitoGel and VesiGel, and Imiquimod for Vesimune. Because there area limited number of suppliers for the raw materials that we use to manufacture our product candidates, we may need to engage alternate suppliers to prevent apossible disruption of the manufacture of the materials necessary to produce our product candidates for our clinical trials, and if approved, ultimately forcommercial sale. We do not have any control over the availability of raw materials. If we or our manufacturers are unable to purchase these raw materials onacceptable terms, at sufficient quality levels, or in adequate quantities, if at all, the development and commercialization of our product candidates or anyfuture product candidates, would be delayed or there would be a shortage in supply, which would impair our ability to meet our development objectives forour product candidates or generate revenues from the sale of any approved products.We expect to continue to rely on these or other subcontractors and suppliers to support our commercial requirements if MitoGel, VesiGel or any of our otherproduct candidates is approved for marketing by the FDA or foreign regulatory authorities. We also rely on a single third-party manufacturer to produce theMMC drug product, or final MMC formulation, necessary for our clinical trial and commercial requirements. We have yet to complete the MMC drugproduct validation process, and scale-up work at this manufacturer that would be required for approval and commercial purposes, and there is a risk that wewill not be able to do so in a timely or satisfactory manner. Even if we establish ourselves as an approved commercial supplier of MMC through this drugproduct manufacturer, we plan to continue to rely on third parties for such production of MMC API, as well as for the raw materials, compounds andcomponents necessary to produce our product candidates and for preclinical studies and clinical trials. We would expect that if we become a commercialsupplier of MMC, through a third-party manufacturer of MMC, it would provide us with enhanced control of material supply for both clinical trials and thecommercial market, enable the more rapid implementation of process changes, and allow for better long-term margins. However, we have no experience as acompany in the commercial supply of drugs and may never be successful as a commercial supplier of MMC.Even if we are successful in being approved as a commercial supplier of MMC, cost-overruns, unexpected delays, equipment failures, labor shortages, naturaldisasters, power failures, production failures or product recalls, and numerous other factors could prevent us from realizing the intended benefits of our salesstrategy and have a material adverse effect on our business. Further, establishing ourselves as a commercial supplier of MMC, if we choose to pursue this, willrequire additional investment, will be time-consuming and may be subject to delays, including because of shortage of labor, compliance with regulatoryrequirements or receipt of necessary regulatory approvals. In addition, building out our MMC commercial supply capabilities may cost more than wecurrently anticipate, and delays or problems may adversely impact our ability to provide supply for the development and commercialization of our productcandidates as well as our financial condition.Moreover, before we can begin to commercially manufacture our product candidates, whether in a third-party facility or in our own facility, once established,we must obtain regulatory approval from FDA for our manufacturing process and facility in order to sell such products in the United States. A manufacturingauthorization would also have to be obtained from the appropriate European Union regulatory authorities in order sell such products in the European Union.In order to obtain approval, we will need to ensure that all of the processes, methods and equipment of such manufacturing facilities are compliant withcGMP, and perform extensive audits of vendors, contract laboratories and suppliers. If any vendors, contract laboratories or suppliers is found to be out ofcompliance with cGMP, we may experience delays or disruptions in manufacturing while we work with these third parties to remedy the violation or while wework to identify suitable replacement vendors. The cGMP requirements govern quality control of the manufacturing process and documentation policies andprocedures. In complying with cGMP, we will be obligated to expend time, money and effort in production, record keeping and quality control to assure thatthe product meets applicable specifications and other requirements. If we fail to comply with these requirements, we would be subject to possible regulatoryaction and may not be permitted to sell any product candidate that we may develop.Our continuing reliance on third party subcontractors and suppliers entails a number of risks, including reliance on the third party for regulatory complianceand quality assurance, the possible breach of the manufacturing or supply agreement by the third party, and the possible termination or nonrenewal of theagreement by the third party at a time that is costly or inconvenient for us. In addition, third party subcontractors and suppliers may not be able to complywith cGMP or quality system regulation, also called QSR, or similar regulatory requirements outside the United States. If any of these risks transpire, we maybe unable to timely retain alternate subcontractors or suppliers on acceptable terms and with sufficient quality standards and production capacity, which maydisrupt and delay our clinical trials or the manufacture and commercial sale of our product candidates, if approved.Our failure or the failure of our third-party subcontractors and suppliers to comply with applicable regulations could result in sanctions being imposed on us,including fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of products, operatingrestrictions and criminal prosecutions, any of which could significantly and adversely affect17 supplies of MitoGel, VesiGel or any of our other product candidates that we may develop. Any failure or refusal to supply or any interruption in supply of thecomponents for MitoGel, VesiGel or any other product candidates or products that we may develop could delay, prevent or impair our clinical developmentor commercialization efforts.Failure to obtain marketing approval in international jurisdictions would prevent our product candidates from being marketed abroad.In order to market and sell our products in the European Union and other jurisdictions, we or our third-party collaborators must obtain separate marketingapprovals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and can involve additionaltesting. The time required to obtain approval may differ substantially from that required to obtain FDA approval. Regulatory approval processes outside theUnited States generally include all of the risks associated with obtaining FDA approval. In addition, in many countries outside the United States, it isrequired that the product be approved for reimbursement before the product can be approved for sale in that country. We may not obtain approvals fromregulatory authorities outside the United States on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory authorities in othercountries or jurisdictions, and approval by one regulatory authority outside the United States does not ensure approval by regulatory authorities in othercountries or jurisdictions or by the FDA. We may not be able to submit for marketing approvals and may not receive the necessary approvals tocommercialize our product candidates in any particular market.We intend to rely on third parties and consultants to assist us in conducting our single pivotal Phase 3 clinical trial for MitoGel, our Phase 2b clinical trialfor VesiGel and certain clinical trials for our other product candidates. If these third parties or consultants do not successfully carry out their contractualduties or meet expected deadlines, we may be unable to obtain regulatory approval for or commercialize MitoGel, VesiGel or any of our other productcandidates.We do not have the ability to independently conduct many of our preclinical studies or our clinical trials. We rely on medical institutions, clinicalinvestigators, contract laboratories, and other third parties, such as CROs to conduct clinical trials on our product candidates. Third parties play a significantrole in the conduct of our clinical trials and the subsequent collection and analysis of data. These third parties are not our employees, and except for remediesavailable to us under our agreements, we have limited ability to control the amount or timing of resources that any such third party will devote to our clinicaltrials. Due to the limited drug development for non-muscle invasive urothelial cancers over the past 15 years, neither we nor any third-party clinicalinvestigators, CROs and/or consultants are likely to have extensive experience conducting clinical trials for the indications we are targeting. If our CROs orany other third parties upon which we rely for administration and conduct of our clinical trials do not successfully carry out their contractual duties orobligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to thefailure to adhere to our clinical protocols, regulatory requirements, or for other reasons, or if they otherwise perform in a substandard manner, our clinicaltrials may be extended, delayed, suspended or terminated, and we may not be able to complete development of, obtain regulatory approval for, orsuccessfully commercialize our product candidates.We and the third parties upon whom we rely are required to comply with Good Clinical Practice, or GCP, regulations, which are regulations and guidelinesenforced by regulatory authorities around the world for products in clinical development. Regulatory authorities enforce these GCP regulations throughperiodic inspections of clinical trial sponsors, principal investigators and clinical trial sites. If we or our third parties fail to comply with applicable GCPregulations, the clinical data generated in our clinical trials may be deemed unreliable and our submission of marketing applications may be delayed, or theregulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that, uponinspection, a regulatory authority will determine that any of our clinical trials comply or complied with applicable GCP regulations. In addition, our clinicaltrials must be conducted with material produced under current cGMP regulations, which are enforced by regulatory authorities. Our failure to comply withthese regulations may require us to repeat clinical trials, which would delay the regulatory approval process. Moreover, our business may be impacted if ourCROs, clinical investigators or other third parties violate federal or state fraud and abuse or false claims laws and regulations or healthcare privacy andsecurity laws.In order for our clinical trials to be carried out effectively and efficiently, it is imperative that our CROs and other third parties communicate and coordinatewith one another. Moreover, our CROs and other third parties may also have relationships with other commercial entities, some of which may compete withus. Our CROs and other third parties may terminate their agreements with us upon as few as 30 days’ notice under certain circumstances. If our CROs or otherthird parties conducting our clinical trials do not perform their contractual duties or obligations, experience work stoppages, do not meet expected deadlines,terminate their agreements with us or need to be replaced, or if the quality or accuracy of the clinical data they obtain is compromised due to the failure toadhere to our clinical trial protocols or GCPs, or for any other reason, we may need to conduct additional clinical trials or enter into new arrangements withalternative CROs, clinical investigators or other third parties. We may be unable to enter into arrangements with alternative CROs on commerciallyreasonable terms, or at all. Switching or adding CROs, clinical investigators or other third parties can involve substantial cost and require extensivemanagement time and focus. In addition, there is a natural transition period when a18 new CRO commences work. As a result, delays may occur, which can impact our ability to meet our desired clinical development timelines. Although wecarefully manage our relationship with our CROs, clinical investigators and other third parties, there can be no assurance that we will not encounter suchchallenges or delays in the future or that these delays or challenges will not have a negative impact on our business, prospects, financial condition or resultsof operations.Our ability to market our product candidates, if approved, will be limited to certain indications. If we want to expand the indications for which we maymarket our products, we will need to obtain additional regulatory approvals, which may not be granted.We are currently developing MitoGel for the treatment of low-grade UTUC, and VesiGel and Vesimune for the treatment of various forms of bladder cancer.The FDA and other applicable regulatory agencies will restrict our ability to market or advertise our products to the scope of the approved label for theapplicable product and for no other indications, which could limit physician and patient adoption. We may attempt to develop and, if approved, promote andcommercialize new treatment indications for our products in the future, but we cannot predict when or if we will receive the regulatory approvals required todo so. Failure to receive such approvals will prevent us from promoting or commercializing new treatment indications. In addition, we would be required toconduct additional clinical trials or studies to support approvals for additional indications, which would be time consuming and expensive, and may produceresults that do not support regulatory approvals. If we do not obtain additional regulatory approvals, our ability to expand our business will be limited.If our product candidates are approved for marketing, and we are found to have improperly promoted off-label uses, or if physicians misuse our products,we may become subject to prohibitions on the sale or marketing of our products, significant sanctions, and product liability claims, and our image andreputation within the industry and marketplace could be harmed.The FDA and other regulatory agencies strictly regulate the marketing and promotional claims that are made about drug products. In particular, a productmay not be promoted for uses or indications that are not approved by the FDA or such other regulatory agencies as reflected in the product’s approvedlabeling. For example, if we receive marketing approval for MitoGel for the treatment of low-grade UTUC, the first indication we are pursuing, we cannotpromote the use of our product in a manner that is inconsistent with the approved label. However, physicians are able, in their independent medicaljudgment, to use MitoGel on their patients in an off-label manner, such as for the treatment of other urology indications. If we are found to have promotedsuch off-label uses, we may receive warning letters and become subject to significant liability, which would harm our business. The federal government haslevied large administrative, civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging inoff-label promotion. If we become the target of such an investigation or prosecution based on our marketing and promotional practices, we could face similarsanctions, which would harm our business. In addition, management’s attention could be diverted from our business operations, significant legal expensescould be incurred, and our reputation could be damaged. The FDA has also requested that companies enter into consent decrees or permanent injunctionsunder which specified promotional conduct is changed or curtailed. If we are deemed by the FDA to have engaged in the promotion of our products for off-label use, we could be subject to prohibitions on the sale or marketing of our products or significant fines and penalties, and the imposition of these sanctionscould also affect our reputation with physicians, patients and caregivers, and our position within the industry.Physicians may also misuse our products or use improper techniques, potentially leading to adverse results, side effects or injury, which may lead to productliability claims. If our products are misused or used with improper technique, we may become subject to costly litigation. Product liability claims coulddivert management’s attention from our core business, be expensive to defend, and result in sizable damage awards against us that may not be covered byinsurance. We currently carry product liability insurance covering our clinical trials with policy limits that we believe are customary for similarly situatedcompanies and adequate to provide us with coverage for foreseeable risks. Although we maintain such insurance, any claim that may be brought against uscould result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of ourinsurance coverage. Furthermore, the use of our products for conditions other than those approved by the FDA may not effectively treat such conditions,which could harm our reputation in the marketplace among physicians and patients.If we fail to manage our growth effectively, our business could be disrupted.As of December 31, 2017, we had 42 full-time employees and four part-time employees, of whom all except 9 are based in Israel. We will need to continue toexpand our development, quality, sales, managerial, operational, finance, marketing and other resources to manage our operations and clinical trials,continue our development activities and commercialize our product candidates, if approved. Our management, personnel, systems and facilities currently inplace may not be adequate to support this future growth. Our need to effectively execute our expansion strategy requires that we: •manage our clinical trials effectively; •identify, recruit, retain, incentivize and integrate additional employees;19 •manage our internal development efforts effectively while carrying out our contractual obligations to third parties; and •continue to improve our operational, financial and management controls, reporting systems and procedures.Due to our limited financial resources and our limited experience in managing a larger company, we may not be able to effectively manage the expansion ofour operations or recruit and train additional qualified personnel. The physical expansion of our operations may lead to significant costs and may divert ourmanagement and business development resources. Any inability to manage expansion could delay the execution of our development and strategic objectivesor disrupt our operations; and if we are not successful in commercializing our product candidates, either on our own or through collaborations with one ormore third parties, our revenues will suffer and we would incur significant additional losses.If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of any of our otherproducts we develop.We face an inherent risk of product liability as a result of the clinical testing of our product candidates and will face an even greater risk if we commercializeany products. For example, we may be sued if any product we develop allegedly causes injury or is found to be otherwise unsuitable during product testing,manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warnof dangers inherent in the product, negligence, strict liability and a breach of warranties. Claims could also be asserted under state consumer protection acts.If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization ofour products. Even a successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liabilityclaims may result in: •decreased demand for our product candidates or products we develop; •injury to our reputation and significant negative media attention; •withdrawal of clinical trial participants or cancellation of clinical trials; •costs to defend the related litigation, which may be only partially recoverable even in the event of successful defenses; •a diversion of management’s time and our resources; •substantial monetary awards to trial participants or patients; •regulatory investigations, product recalls, withdrawals or labeling, marketing or promotional restrictions; •loss of revenues; •exhaustion of any available insurance and our capital resources; and •the inability to commercialize any product we develop.Our inability to obtain and maintain sufficient product liability insurance at an acceptable cost and scope of coverage to protect against potential productliability claims could prevent or inhibit the commercialization of products we may develop. We currently carry general clinical trial product liabilityinsurance in an amount that we believe is adequate to cover the scope of our ongoing clinical programs. Although we maintain such insurance, any claim thatmay be brought against us could result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or that is inexcess of the limits of our insurance coverage. Our insurance policies also have various exclusions and deductibles, and we may be subject to a productliability claim for which we have no coverage. We will have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coveragelimitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. Moreover, in thefuture, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses. If and when we obtainapproval for marketing MitoGel, VesiGel or any other product candidate, we intend to expand our insurance coverage to include the commercialization ofMitoGel, VesiGel or any other approved product that we may have; however, we may be unable to obtain this liability insurance on commercially reasonableterms.If we fail to attract and keep senior management and key scientific personnel, we may be unable to successfully develop our product candidates, conductour clinical trials and commercialize any of the products we develop.Our success depends in part on our continued ability to attract, retain and motivate highly qualified management, clinical and scientific personnel. Webelieve that our future success is highly dependent upon the contributions of members of our senior management, as well as our senior scientists and othermembers of our management team. The loss of services of any of these individuals could delay or prevent the successful development of our product pipeline,completion of our planned clinical trials or the commercialization of our product candidates.20 Although we have not historically experienced unique difficulties in attracting and retaining qualified employees, we could experience such problems in thefuture. For example, competition for qualified personnel in the pharmaceutical field is intense due to the limited number of individuals who possess the skillsand experience required by our industry. We will need to hire additional personnel as we expand our clinical development and commercial activities. Wemay not be able to attract and retain quality personnel on acceptable terms, or at all. In addition, to the extent we hire personnel from competitors, we may besubject to allegations that they have been improperly solicited or that they have divulged proprietary or other confidential information, or that their formeremployers own their research output. Moreover, although we have established a U.S. subsidiary, we are domiciled in Israel and are predominantly based inIsrael, which may make it difficult to hire necessary U.S.-based personnel.Our internal computer systems, or those of our CROs or other contractors or consultants, may fail or suffer security breaches, which could result in adisruption of our drug development programs.Despite the implementation of security measures, our internal computer systems and those of our CROs and other contractors and consultants are vulnerableto damage from cyber-security threats, including computer viruses, harmful code and unauthorized access, natural disasters, fire, terrorism, war andtelecommunication and electrical failures. If a disruption event were to occur and cause interruptions in our operations, it could result in a material disruptionof our drug development programs. For example, the loss of clinical trial data from completed, ongoing or planned clinical trials could result in delays in ourregulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach results ina loss of or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the furtherdevelopment of our product candidates could be delayed.Under applicable employment laws, we may not be able to enforce covenants not to compete.We generally enter into non-competition agreements as part of our employment agreements with our employees. These agreements generally prohibit ouremployees, if they cease working for us, from competing directly with us or working for our competitors or clients for a limited period. We may be unable toenforce these agreements under the laws of the jurisdictions in which our employees work, and it may be difficult for us to restrict our competitors frombenefitting from the expertise our former employees or consultants developed while working for us.For example, Israeli labor courts have required employers seeking to enforce non-compete undertakings of a former employee to demonstrate that thecompetitive activities of the former employee will harm one of a limited number of material interests of the employer which have been recognized by thecourts as justification for the enforcement of non-compete undertakings, such as the protection of a company’s trade secrets or other intellectual property.Our employees, independent contractors, clinical investigators, CROs, consultants and vendors may engage in misconduct or other improper activities,including noncompliance with regulatory standards and requirements and insider trading.We are exposed to the risk that our employees, independent contractors, clinical investigators, CROs, consultants and vendors may engage in fraudulentconduct or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct, breach of contract or otherunauthorized activities that violate: FDA regulations, including those laws requiring the reporting of true, complete and accurate information to the FDA;manufacturing standards; federal, state and foreign healthcare fraud and abuse laws; or laws that require the reporting of financial information or dataaccurately.Specifically, research, sales, marketing, education and other business arrangements in the healthcare industry are subject to extensive laws intended toprevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws may restrict or prohibit a wide range of pricing, discounting,marketing and promotion, sales commission, customer incentive and other business arrangements. Activities subject to these laws also include the improperuse of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. We have adopted aCorporate Code of Ethics and Conduct, but it is not always possible to identify and deter misconduct by employees and other third parties, and theprecautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us fromgovernmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws. If any such actions are instituted againstus, even if we are successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business. Violations of suchlaws subject us to numerous penalties, including, but not limited to, the imposition of civil, criminal and administrative penalties, damages, monetary fines,disgorgement, individual imprisonment, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similaragreement to resolve allegations of non-compliance with these laws, possible exclusion from participation in Medicare, Medicaid and other federalhealthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which couldadversely affect our ability to operate our business and our results of operations.21 Our business involves the use of hazardous materials and we and our third-party manufacturers and suppliers must comply with environmental laws andregulations, which can be expensive and restrict how we do business.Our research and development activities and our third-party subcontractors’ and suppliers’ activities involve the controlled storage, use and disposal ofhazardous materials owned by us, including Mitomycin C, or MMC, key components of our product candidates, and other hazardous compounds. We andour manufacturers and suppliers are subject to laws and regulations governing the use, manufacture, storage, handling and disposal of these hazardousmaterials. Despite our efforts, we cannot eliminate the risk of contamination. This could cause an interruption of our commercialization efforts and businessoperations, environmental damage resulting in costly clean-up and liabilities under applicable laws and regulations governing the use, storage, handling anddisposal of these materials and specified waste products. Although we believe that the safety procedures utilized by us and our subcontractors and suppliersfor handling and disposing of these materials generally comply with the standards prescribed by these laws and regulations, we cannot guarantee that this isthe case or eliminate the risk of accidental contamination or injury from these materials. In such an event, we may be held liable for any resulting damagesand such liability could exceed our resources and state or federal or other applicable authorities may curtail our use of certain materials and interrupt ourbusiness operations.Furthermore, environmental laws and regulations are complex, change frequently and have tended to become more stringent. We cannot predict the impact ofsuch changes and cannot be certain of our future compliance.Exchange rate fluctuations between the U.S. Dollar and the New Israeli Shekel may negatively affect our earnings.The U.S. dollar is our functional and reporting currency. However, a significant portion of our operating expenses are incurred in New Israeli Shekels, or NIS,which is the lawful currency of the State of Israel. As a result, we are exposed to the risks that the NIS may appreciate relative to the dollar, or, if the NISinstead devalues relative to the dollar, that the inflation rate in Israel may exceed such rate of devaluation of the NIS, or that the timing of such devaluationmay lag behind inflation in Israel. In any such event, the dollar cost of our operations in Israel would increase and our dollar-denominated results ofoperations would be adversely affected. We cannot predict any future trends in the rate of inflation in Israel or the rate of devaluation (if any) of the NISagainst the dollar. For example, even though the level of devaluation of the dollar against the NIS in 2016 was 1.5% and the level of devaluation of the dollaragainst the NIS in 2017 was 9.8%, if the dollar cost of our operations in Israel increases, our dollar-measured results of operations will be adversely affected.Risks Related to Our Intellectual PropertyIf our efforts to obtain, protect or enforce our patents and other intellectual property rights related to our product candidates and technologies are notadequate, we may not be able to compete effectively, and we otherwise may be harmed.Our commercial success depends in part upon our ability to obtain and maintain patent protection and utilize trade secret protection for our intellectualproperty and proprietary technologies, our products and their uses, as well as our ability to operate without infringing upon the proprietary rights of others.We rely upon a combination of patents, trade secret protection and confidentiality agreements, assignment of invention agreements and other contractualarrangements to protect the intellectual property related to hydrogel-based pharmaceutical compositions for optimal delivery of a drug in internal cavitiessuch as the bladder, the method for treating urothelial cancer using hydrogel-based compositions, the method for treating overactive bladder topicallywithout the need for injections, an in-dwelling ureter catheter system for optimal delivery of a drug into the renal cavity, and pharmaceutical compositionscomprising an imidazoquinolin (amine) and lactic acid for use in a method for the treatment of bladder diseases.We seek patent protection for our product candidates, and we have established several patent families comprised of issued patents and pending patentapplications covering our proprietary RTGel formulation technology and the formulations, methods of use and manufacturing aspects of our productcandidates. In the United States, we currently have 13 granted patents that are directed to protect our lead product candidates, MitoGel, VesiGel, BotuGel,Vesimune and RTGel as well as to our future product candidates that are under company research. These patents claim methods, systems, and novelcompositions for treating cancer in internal cavities, in particular urinary tract cancer. These issued patents are expected to expire between 2024 and 2035.Moreover, our IP portfolio includes more than 45 patent applications filed worldwide that are directed to various methods, systems and compositions fortreating cancer locally, by intravesical means. We have four pending patent applications relating to the product candidate BotuGel in the European Union,China and Israel as well as one granted patent in Russia. In addition, we have two granted patents related to Vesimune in the United States as well as twogranted patents in the European Union, two granted patents in Japan and one granted patent in each of Australia, Mexico, China, Russia, and Hong Kong,each of which is expected to remain in effect until 2030. In addition to the issued patents mentioned above, our portfolio includes pending patentapplications relating to Vesimune in the European Union, Hong Kong, Canada, Brazil and Israel. Moreover, we hold five granted patents in the United Statesas well as patent applications filed worldwide that relate to novel formulations of phospholipid drug analogs (saturated lipid conjugate compositions) for thetreatment of urinary tract cancer.22 Limitations on the scope of our intellectual property rights may limit our ability to prevent third parties from designing around such rights and competingagainst us. For example, our patents do not claim a new compound. Rather, the active pharmaceutical ingredients of our products are existing compounds andour granted patents and pending patent applications are directed to, among other things, novel formulations of these existing compounds with our RTGel.Accordingly, other parties may compete with us, for example, by independently developing or obtaining competing topical formulations that design aroundour patent claims, but which may contain the same active ingredients, or by seeking to invalidate our patents. Any disclosure to or misappropriation by thirdparties of our confidential proprietary information could enable competitors to quickly duplicate or surpass our technological achievements, eroding ourcompetitive position in the market.However, the patent applications that we own, or license may fail to result in granted patents in the United States or foreign jurisdictions, or if granted mayfail to prevent a potential infringer from marketing its product or be deemed invalid and unenforceable by a court. Competitors in the field of reverse thermalgel therapies have created a substantial amount of scientific publications, patents and patent applications and other materials relating to their technologies.Our ability to obtain and maintain valid and enforceable patents depends on various factors, including interpretation of our technology and the prior art andwhether the differences between them allow our technology to be patentable. Patent applications and patents granted from them are complex, lengthy andhighly technical documents that are often prepared under very limited time constraints and may not be free from errors that make their interpretationuncertain. The existence of errors in a patent may have an adverse effect on the patent, its scope and its enforceability. Our pending patent applications maynot issue, and the scope of the claims of patent applications that do issue may be too narrow to adequately protect our competitive advantage. Also, ourgranted patents may be subject to challenges or narrowly construed and may not provide adequate protection.We may be subject to claims that we infringe, misappropriate or otherwise violate the intellectual property rights of third parties.Even if our patents do successfully issue, third parties may challenge the validity, enforceability or scope of such granted patents or any other granted patentswe own or license, which may result in such patents being narrowed, invalidated or held unenforceable. For example, patents granted by the European PatentOffice may be opposed by any person within nine months from the publication of their grant. Also, patents granted by the United States Patent andTrademark Office, or USPTO, may be subject to reexamination and other challenges.Furthermore, even if they are not challenged, our patents and patent applications may not adequately protect our intellectual property or prevent others fromdesigning around our claims. To meet such challenges, which are part of the risks and uncertainties of developing and marketing product candidates, we mayneed to evaluate third party intellectual property rights and, if appropriate, to seek licenses for such third party intellectual property or to challenge such thirdparty intellectual property, which may be costly and may or may not be successful, which could also have an adverse effect on the commercial potential forMitoGel, VesiGel and any of our product candidates.We may receive only limited protection, or no protection, from our issued patents and patent applications.If we encounter delays in our clinical trials or regulatory approval of our product candidates, the period of time during which we could market any of ourproduct candidates under patent protection could be reduced. Since patent applications in the United States and most other countries are confidential for aperiod of time after filing, we cannot be certain that we were the first to either (i) file any patent application related to hydrogel-based pharmaceuticalcompositions for optimal delivery of a drug in internal cavities such as the bladder, the method for treating urothelial cancer using hydrogel-basedcompositions, the method for treating overactive bladder topically without the need for injections, an in-dwelling ureter catheter system for optimal deliveryof a drug into the renal cavity, and pharmaceutical compositions comprising an imidazoquinolin (amine) and lactic acid for use in a method for the treatmentof bladder diseases or any of our product candidates or (ii) conceive and invent any of the inventions claimed in our patents or patent applications.The patent application process, also known as patent prosecution, is expensive and time consuming, and we or any future licensors and licensees may not beable to prepare, file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we or anyfuture licensors or licensees will fail to identify patentable aspects of inventions made in the course of development and commercialization activities beforeit is too late to obtain patent protection on them. Therefore, these and any of our patents and applications may not be prosecuted and enforced in a mannerconsistent with the best interests of our business. It is possible that defects of form in the preparation or filing of our patents or patent applications may exist,or may arise in the future, for example with respect to proper priority claims, inventorship, etc., although we are unaware of any such defects that we believeare of material import. If we or any future licensors or licensees fail to establish, maintain or protect such patents and other intellectual property rights, suchrights may be reduced or eliminated. If any future licensors or licensees, are not fully cooperative or disagree with us as to the prosecution, maintenance orenforcement of any patent rights, such patent rights could be compromised. If there are material defects in the form or preparation of our patents or patentapplications, such patents or applications may be invalid and unenforceable. Any of these outcomes could impair our ability to prevent competition fromthird parties, which may have an adverse impact on our business.23 The strength of patents in the pharmaceutical field involves complex legal and scientific questions and can be uncertain. This uncertainty includes changesto the patent laws through either legislative action to change statutory patent law or court action that may reinterpret existing law in ways affecting the scopeor validity of issued patents. The patent applications that we own or in-license may fail to result in issued patents in the United States or foreign countrieswith claims that cover our product candidates. Even if patents do successfully issue from the patent applications that we own or in-license, third parties maychallenge the validity, enforceability or scope of such patents, which may result in such patents being narrowed, invalidated or held unenforceable. Forexample, patents granted by the European Patent Office may be challenged, also known as opposed, by any person within nine months from the publicationof their grant. Any successful challenge to our patents could deprive us of exclusive rights necessary for the successful commercialization of our productcandidates. Furthermore, even if they are unchallenged, our patents may not adequately protect our product candidates, provide exclusivity for our productcandidates, or prevent others from designing around our claims. If the breadth or strength of protection provided by the patents we hold or pursue with respectto our product candidates is challenged, it could dissuade companies from collaborating with us to develop or threaten our ability to commercialize ourproduct candidates.Patents have a limited lifespan. In the United States, the natural expiration of a patent is generally 20 years after it is filed. Various extensions may beavailable; however, the life of a patent, and the protection it affords, is limited. Without patent protection for our product candidates, we may be open tocompetition from generic versions of our product candidates. Further, if we encounter delays in our development efforts, including our clinical trials, theperiod of time during which we could market our product candidates under patent protection would be reduced.A considerable number of our patents and patent applications are entitled to effective filing dates prior to March 16, 2013. For U.S. patent applications inwhich patent claims are entitled to a priority date before March 16, 2013, an interference proceeding can be provoked by a third party, for example acompetitor, or instituted by the USPTO to determine who was the first to invent any of the subject matter covered by those patent claims. An unfavorableoutcome could require us to cease using the related technology or to attempt to license rights from the prevailing party. Our business could be harmed if theprevailing party does not offer us a license on commercially reasonable terms. Our participation in an interference proceeding may fail and, even if successful,may result in substantial costs and distract our management.Our trade secrets may not have sufficient intellectual property protection.In addition to the protection afforded by patents, we also rely on trade secret protection to protect proprietary know-how that may not be patentable or thatwe elect not to patent, processes for which patents may be difficult to obtain or enforce, and any other elements of our product candidates, and our productdevelopment processes (such as manufacturing and formulation technologies) that involve proprietary know-how, information or technology that is notcovered by patents. However, trade secrets can be difficult to protect. If the steps taken to maintain our trade secrets are deemed inadequate, we may haveinsufficient recourse against third parties for misappropriating any trade secrets. Misappropriation or unauthorized disclosure of our trade secrets couldsignificantly affect our competitive position and may have an adverse effect on our business. Furthermore, trade secret protection does not preventcompetitors from independently developing substantially equivalent information and techniques and we cannot guarantee that our competitors will notindependently develop substantially equivalent information and techniques. The FDA, as part of its Transparency Initiative, is currently considering whetherto make additional information publicly available on a routine basis, including information that we may consider to be trade secrets or other proprietaryinformation, and it is not clear at the present time how the FDA’s disclosure policies may change in the future, if at all.In an effort to protect our trade secrets and other confidential information, we require our employees, consultants, advisors, and any other third parties thathave access to our proprietary know-how, information or technology, for example, third parties involved in the formulation and manufacture of our productcandidates, and third parties involved in our clinical trials to execute confidentiality agreements upon the commencement of their relationships with us.These agreements require that all confidential information developed by the individual or made known to the individual by us during the course of theindividual’s relationship with us is kept confidential and not disclosed to third parties. However, we cannot be certain that our trade secrets and otherconfidential proprietary information will not be disclosed despite having such confidentiality agreements. Adequate remedies may not exist in the event ofunauthorized use or disclosure of our trade secrets. In addition, in some situations, these confidentiality agreements may conflict with, or be subject to, therights of third parties with whom our employees, consultants, or advisors have previous employment or consulting relationships. To the extent that ouremployees, consultants or contractors use any intellectual property owned by third parties in their work for us, disputes may arise as to the rights in anyrelated or resulting know-how and inventions. If we are unable to prevent unauthorized material disclosure of our trade secrets to third parties, we may not beable to establish or maintain a competitive advantage in our market, which could harm our business, operating results and financial condition.Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our products.As is the case with other pharmaceutical companies, our success is heavily dependent on intellectual property, particularly on obtaining and enforcingpatents. Obtaining and enforcing patents in the pharmaceutical industry involves both technological and legal24 complexity, and therefore, is costly, time-consuming and inherently uncertain. In addition, the United States has recently enacted and is currentlyimplementing wide-ranging patent reform legislation. Further, recent U.S. Supreme Court rulings have either narrowed the scope of patent protectionavailable in certain circumstances or weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to ourability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained.For our U.S. patent applications containing a claim not entitled to priority before March 16, 2013, there is a greater level of uncertainty in the patent law. InSeptember 2011, the Leahy-Smith America Invents Act, or the America Invents Act, or AIA, was signed into law. The AIA includes a number of significantchanges to U.S. patent law, including provisions that affect the way patent applications will be prosecuted and may also affect patent litigation. The USPTOis currently developing regulations and procedures to govern administration of the AIA, and many of the substantive changes to patent law associated withthe AIA. It is not clear what other, if any, impact the AIA will have on the operation of our business. Moreover, the AIA and its implementation could increasethe uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which couldharm our business and financial condition.An important change introduced by the AIA is that, as of March 16, 2013, the United States transitioned to a “first-to-file” system for deciding which partyshould be granted a patent when two or more patent applications are filed by different parties claiming the same invention. A third party that files a patentapplication in the USPTO after that date but before us could therefore be awarded a patent covering an invention of ours even if we had made the inventionbefore it was made by the third party. This will require us to be cognizant going forward of the time from invention to filing of a patent application.Furthermore, our ability to obtain and maintain valid and enforceable patents depends on whether the differences between our technology and the prior artallow our technology to be patentable over the prior art. Since patent applications in the United States and most other countries are confidential for a periodof time after filing, we cannot be certain that we were the first to either (i) file any patent application related to our product candidates or (ii) invent any of theinventions claimed in our patents or patent applications.Among some of the other changes introduced by the AIA are changes that limit where a patentee may file a patent infringement suit and provideopportunities for third parties to challenge any issued patent in the USPTO. This applies to all of our U.S. patents, even those issued before March 16, 2013.Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in United States federal court necessary to invalidate apatent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the sameevidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTOprocedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action.Depending on decisions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictableways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.Obtaining and maintaining our patent protection depends on compliance with various procedural, documentary, fee payment and other requirementsimposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similarprovisions during the patent prosecution process.Periodic maintenance fees and various other governmental fees on any issued patent and/or pending patent applications are due to be paid to the USPTO andforeign patent agencies in several stages over the lifetime of a patent or patent application. We have systems in place to remind us to pay these fees, and weemploy an outside firm and rely on our outside counsel to pay these fees. While an inadvertent lapse may sometimes be cured by payment of a late fee or byother means in accordance with the applicable rules, there are many situations in which noncompliance can result in abandonment or lapse of the patent orpatent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. If we fail to maintain the patents and patent applicationsdirected to our product candidates, our competitors might be able to enter the market earlier than should otherwise have been the case, which could harm ourbusiness.We may not be able to protect our intellectual property rights throughout the world.Filing, prosecuting and defending patents on our product candidates in all countries throughout the world would be prohibitively expensive. Therequirements for patentability may differ in certain countries, particularly developing countries. For example, unlike other countries, China has a heightenedrequirement for patentability, and specifically requires a detailed description of medical uses25 of a claimed drug. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as laws in the United States.Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States. Competitors may use ourtechnologies in jurisdictions where we have not obtained patent protection to develop their own products and further, may export otherwise infringingproducts to territories where we have patent protection, but enforcement on infringing activities is inadequate. These products may compete with ourproducts, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systemsof certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularlythose relating to pharmaceuticals, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violationof our proprietary rights generally.Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of ourbusiness, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing, and could provoke thirdparties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not becommercially meaningful. In addition, certain countries in Europe and certain developing countries, including India and China, have compulsory licensinglaws under which a patent owner may be compelled to grant licenses to third parties. In those countries, we may have limited remedies if our patents areinfringed or if we are compelled to grant a license to our patents to a third party, which could materially diminish the value of those patents. This could limitour potential revenue opportunities. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain asignificant commercial advantage from the intellectual property that we own or license. Finally, our ability to protect and enforce our intellectual propertyrights may be adversely affected by unforeseen changes in foreign intellectual property laws.If we are unable to protect our trademarks from infringement, our business prospects may be harmed.We own trademarks that identify MitoGel, VesiGel and Vesimune and have registered these trademarks in the United States and Israel. Although we takesteps to monitor the possible infringement or misuse of our trademarks, it is possible that third parties may infringe, dilute or otherwise violate our trademarkrights. Any unauthorized use of our trademarks could harm our reputation or commercial interests. In addition, our enforcement against third-party infringersor violators may be unduly expensive and time-consuming, and the outcome may be an inadequate remedy.We may become involved in lawsuits to protect or enforce our patents or other intellectual property or the patents of our licensors, which could beexpensive and time consuming.Third parties may infringe or misappropriate our intellectual property, including our existing patents, patents that may issue to us in the future, or the patentsof our licensors to which we have a license. As a result, we may be required to file infringement claims to stop third-party infringement or unauthorized use.Further, we may not be able to prevent, alone or with our licensors, misappropriation of our intellectual property rights, particularly in countries where thelaws may not protect those rights as fully as in the United States.Generic drug manufacturers may develop, seek approval for, and launch generic versions of our products. If we file an infringement action against such ageneric drug manufacturer, that company may challenge the scope, validity or enforceability of our or our licensors’ patents, requiring us and/or our licensorsto engage in complex, lengthy and costly litigation or other proceedings.For example, if we or one of our licensors initiated legal proceedings against a third party to enforce a patent covering our product candidates, the defendantcould counterclaim that the patent covering our product candidates is invalid and/or unenforceable. In patent litigation in the United States, defendantcounterclaims alleging invalidity and/or unenforceability are commonplace, and there are numerous grounds upon which a third party can assert invalidity orunenforceability of a patent.In addition, within and outside of the United States, there has been a substantial amount of litigation and administrative proceedings, including interferenceand reexamination proceedings before the USPTO or oppositions and other comparable proceedings in various foreign jurisdictions, regarding patent andother intellectual property rights in the pharmaceutical industry. Recently, the AIA introduced new procedures including inter partes review and post grantreview. The implementation of these procedures brings uncertainty to the possibility of challenges to our patents in the future, including challenges bycompetitors who perceive our patents as blocking entry into the market for their products, and the outcome of such challenges.Such litigation and administrative proceedings could result in revocation of our patents or amendment of our patents such that they do not cover our productcandidates. They may also put our pending patent applications at risk of not issuing or issuing with limited and potentially inadequate scope to cover ourproduct candidates. The outcome following legal assertions of invalidity and26 unenforceability is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which weand the patent examiner were unaware during prosecution. Additionally, it is also possible that prior art of which we are aware, but which we do not believeaffects the validity or enforceability of a claim, may, nonetheless, ultimately be found by a court of law or an administration panel to affect the validity orenforceability of a claim. If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all,of the patent protection on our product candidates. Such a loss of patent protection could have a negative impact on our business.Enforcing our or our licensor’s intellectual property rights through litigation is very expensive, particularly for a company of our size, and time-consuming.Some of our competitors may be able to sustain the costs of litigation more effectively than we can because of greater financial resources. Patent litigationand other proceedings may also absorb significant management time.Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could impair our ability to compete in the marketplace.The occurrence of any of the foregoing could harm our business, financial condition or results of operations.Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or administrative proceedings, thereis a risk that some of our confidential information could be compromised by disclosure. In addition, during the course of litigation or administrativeproceedings, there could be public announcements of the results of hearings, motions or other interim proceedings or developments or public access torelated documents. If investors perceive these results to be negative, the market price for our ordinary shares could be significantly harmed.We may become subject to claims for remuneration or royalties for assigned service invention rights by our employees, which could result in litigation andadversely affect our business.A significant portion of our intellectual property has been developed by our employees during their employment. Under the Israeli Patent Law, 5727-1967, orthe Patent Law, inventions conceived by an employee during the scope of his or her employment with a company are regarded as “service inventions.” TheIsraeli Compensation and Royalties Committee, or the Committee, a body constituted under the Patent Law, has previously held, in certain cases, thatemployees may be entitled to remuneration for service inventions that they develop during their service for a company despite their explicit waiver of suchright. Therefore, although we enter into agreements with our employees pursuant to which they waive their right to special remuneration for serviceinventions created in the scope of their employment or engagement and agree that any such inventions are owned exclusively by us, we may face claims byemployees demanding remuneration beyond their regular salary and benefits.Third-party claims alleging intellectual property infringement may adversely affect our business.Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties, for example, the intellectualproperty rights of competitors. Our research, development and commercialization activities may be subject to claims that we infringe or otherwise violatepatents owned or controlled by third parties. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties,exist in the fields in which we are developing our product candidates. As the biotechnology and pharmaceutical industries expand and more patents areissued, the risk increases that our activities related to our product candidates may give rise to claims of infringement of the patent rights of others. We cannotassure you that our product candidates will not infringe existing or future patents. We may not be aware of patents that have already issued that a third partymight assert are infringed by our product candidates. It is also possible that patents of which we are aware, but which we do not believe are relevant to ourproduct candidates, could nevertheless be found to be infringed by our product candidates. Nevertheless, we are not aware of any issued patents that webelieve would prevent us from marketing our product candidates, if approved. There may also be patent applications that have been filed but not publishedthat, when issued as patents, could be asserted against us.Third parties making claims against us for infringement or misappropriation of their intellectual property rights may seek and obtain injunctive or otherequitable relief, which could effectively block our ability to further develop and commercialize our product candidates. Further, if a patent infringement suitwere brought against us, we could be forced to stop or delay research, development, manufacturing or sales of the product or product candidate that is thesubject of the suit. Defense of these claims, regardless of their merit, would cause us to incur substantial expenses and, and would be a substantial diversion ofmanagement time and employee resources from our business. In the event of a successful claim of infringement against us by a third party, we may have to (i)pay substantial damages, including treble damages and attorneys’ fees if we are found to have willfully infringed the third party’s patents; (ii) obtain one ormore licenses from the third party; (iii) pay royalties to the third party; and/or (iv) redesign any infringing products. Redesigning any infringing productsmay be impossible or require substantial time and monetary expenditure. Further, we cannot predict whether any required license would be available at all orwhether it would be available on commercially reasonable terms. In the event that we could not obtain a license, we may be unable to further develop andcommercialize our product candidates, which could harm our business significantly. Even if we are able to obtain a license, the license would likely obligateus to pay license fees or royalties or both, and the rights granted to us might be nonexclusive, which could result in our competitors gaining access to thesame intellectual property. Ultimately, we could be prevented from commercializing a product, or be forced to cease some aspect of our business operations,if, as a result of actual or threatened patent infringement claims, we are unable to enter into licenses on acceptable terms.27 Defending ourselves or our licensors in litigation is very expensive, particularly for a company of our size, and time-consuming. Some of our competitorsmay be able to sustain the costs of litigation or administrative proceedings more effectively than we can because of greater financial resources. Patentlitigation and other proceedings may also absorb significant management time. Uncertainties resulting from the initiation and continuation of patentlitigation or other proceedings could impair our ability to compete in the marketplace. The occurrence of any of the foregoing could harm our business,financial condition or results of operations.We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information ofthird parties.We employ individuals who were previously employed at other biotechnology or pharmaceutical companies. We may be subject to claims that we or ouremployees, consultants or independent contractors have inadvertently or otherwise improperly used or disclosed confidential information of these thirdparties or our employees’ former employers. Further, we may be subject to ownership disputes in the future arising, for example, from conflicting obligationsof consultants or others who are involved in developing our product candidates. We may also be subject to claims that former employees, consultants,independent contractors, collaborators or other third parties have an ownership interest in our patents or other intellectual property. Litigation may benecessary to defend against these and other claims challenging our right to and use of confidential and proprietary information. If we fail in defending anysuch claims, in addition to paying monetary damages, we may lose our rights therein. Such an outcome could have a negative impact on our business. Even ifwe are successful in defending against these claims, litigation could result in substantial cost and be a distraction to our management and employees.Risks Related to Government RegulationIf the FDA does not conclude that MitoGel, VesiGel, or our other product candidates satisfy the requirements under Section 505(b)(2) of the Federal FoodDrug and Cosmetic Act, or Section 505(b)(2), or if the requirements for such product candidates are not as we expect, the approval pathway for theseproduct candidates will likely take significantly longer, cost significantly more and entail significantly greater complications and risks than anticipated,and in either case may not be successful.We commenced a single pivotal Phase 3 clinical trial for MitoGel and expect to commence a Phase 2b clinical trial of VesiGel under the FDA’s Section505(b)(2) regulatory pathway. The Drug Price Competition and Patent Term Restoration Act of 1984, also known as the Hatch-Waxman Act, added Section505(b)(2) to the Federal Food, Drug and Cosmetic Act. Section 505(b)(2) permits the filing of an NDA where at least some of the information required forapproval comes from studies that were not conducted by or for the applicant, and for which the applicant has not received a right of reference, which couldexpedite the development program for MitoGel, VesiGel and our other product candidates by potentially decreasing the amount of preclinical and clinicaldata that we would need to generate in order to obtain FDA approval. However, while we believe that our product candidates are reformulations of existingdrugs or biologics and, therefore, will not be treated as new chemical entities, or NCEs, the submission of an NDA under the Section 505(b)(2) or similarregulatory pathway does not preclude the FDA from determining that the product candidate that is the subject of such submission is an NCE and therefore noteligible for review under such regulatory pathway.If the FDA does not allow us to pursue the Section 505(b)(2) or similar regulatory pathway as anticipated, we may need to conduct additional preclinicalexperiments and clinical trials, provide additional data and information, and meet additional standards for regulatory approval. If this were to occur, the timeand financial resources required to obtain FDA approval for these product candidates, and complications and risks associated with these product candidates,would likely increase significantly. Moreover, inability to pursue the Section 505(b)(2) or similar regulatory pathway could result in new competitiveproducts reaching the market more quickly than our product candidates, which would likely harm our competitive position and prospects. Even if we areallowed to pursue the Section 505(b)(2) or similar regulatory pathway, our product candidates may not receive the requisite approvals for commercialization.In addition, notwithstanding the approval of a number of products by the FDA under Section 505(b)(2) over the last few years, certain competitors and othershave objected to the FDA’s interpretation of Section 505(b)(2). If the FDA’s interpretation of Section 505(b)(2) is successfully challenged, the FDA may berequired to change its 505(b)(2) policies and practices, which could delay or even prevent the FDA from approving any NDA that we submit under Section505(b)(2). In addition, the pharmaceutical industry is highly competitive, and Section 505(b)(2) NDAs are subject to special requirements designed to protectthe patent rights of sponsors of previously approved drugs that are referenced in a Section 505(b)(2) NDA. These requirements may give rise to patentlitigation and mandatory delays in approval of our potential future NDAs for up to 30 months depending on the outcome of any litigation. It is notuncommon for a manufacturer of an approved product to file a citizen petition with the FDA seeking to delay approval of, or impose additional approvalrequirements for, pending competing products. If successful, such petitions can significantly delay, or even prevent, the approval of the new product.However, even if the FDA ultimately denies such a petition, the FDA may substantially delay approval while it considers and responds to the petition. Inaddition, even if we are able to utilize the Section 505(b)(2) regulatory pathway for our product candidates, there is no guarantee this would ultimately leadto faster product development or earlier approval.28 Moreover, even if these product candidates are approved under the Section 505(b)(2) pathway, as the case may be, the approval may be subject to limitationson the indicated uses for which the products may be marketed or to other conditions of approval or may contain requirements for costly post-marketingtesting and surveillance to monitor the safety or efficacy of the products.Fast track designation for one or more of our product candidates may not actually lead to a faster development or regulatory review or approval process.In August 2017, we received fast track designation for MitoGel for the treatment of UTUC. If a product is intended for the treatment of a serious condition,and nonclinical or clinical data demonstrate the potential to address unmet medical need for this condition, a product sponsor may apply for FDA fast trackdesignation. Even though we have received fast track designation for MitoGel for the treatment of UTUC, fast track designation does not ensure that we willreceive marketing approval or that approval will be granted within any particular timeframe. We may not experience a faster development or regulatoryreview or approval process with fast track designation compared to conventional FDA procedures. In addition, the FDA may withdraw fast track designationif it believes that the designation is no longer supported by data from our clinical development program. Fast track designation alone does not guaranteequalification for the FDA’s priority review procedures.We expect current and future legislation affecting the healthcare industry, including healthcare reform, to impact our business generally and to increaselimitations on reimbursement, rebates and other payments, which could adversely affect third-party coverage of our products, our operations, and/or howmuch or under what circumstances healthcare providers will prescribe or administer our products, if approved.The United States and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals to change the healthcaresystem in ways that could affect our ability to sell our products profitably. Among policy makers and payors in the United States and elsewhere, there issignificant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality or expanding access.In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislativeinitiatives.For example, in March 2010, President Obama signed into law the Patient Protection and Affordable Care Act and the Health Care and EducationAffordability Reconciliation Act of 2010, or collectively, the ACA, a law intended, among other things, to broaden access to health insurance, improvequality of care, and reduce or constrain the growth of healthcare spending.Provisions of the ACA relevant to the pharmaceutical industry include the following: •an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic agents, apportionedamong these entities according to their market share in certain government healthcare programs, not including orphan drug sales; •an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13% of the averagemanufacturer price for most branded and generic drugs, respectively; •a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% (70% commencing January 1, 2019) point-of-sale discounts on negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for themanufacturer’s outpatient drugs to be covered under Medicare Part D; •extension of manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed careorganizations; •expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additionalindividuals and by adding new mandatory eligibility categories for certain individuals with income at or below 133% of the Federal PovertyLevel, thereby potentially increasing manufacturers’ Medicaid rebate liability; •expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program; •new requirements to report annually certain financial arrangements with physicians and teaching hospitals; as defined in the ACA and itsimplementing regulations, including reporting any payment or “transfer of value” provided to physicians and teaching hospitals and anyownership and investment interests held by physicians and their immediate family members during the preceding calendar year; •expansion of healthcare fraud and abuse laws, including the federal civil False Claims Act and the federal Anti-Kickback Statute, new governmentinvestigative powers and enhanced penalties for noncompliance; and •a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in and conduct comparative clinical effectiveness research,along with funding for such research.29 There have been judicial and Congressional challenges to certain aspects of the ACA. As a result, there have been delays in the implementation of, and actiontaken to repeal or replace, certain aspects of the ACA. For example, since January 2017, President Trump has signed two executive orders and other directivesdesigned to delay, circumvent, or loosen certain requirements mandated by the ACA. Concurrently, Congress has considered legislation that would repeal orrepeal and replace all or part of the ACA. The recently enacted Tax Cuts and the Jobs Act also includes a provision that repeals, effective January 1, 2019, thetax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a yearthat is commonly referred to as the “individual mandate.” Additionally, on January 22, 2018, President Trump signed a continuing resolution onappropriations for fiscal year 2018 that delayed the implementation of certain ACA-mandated fees, including the so-called “Cadillac” tax on certain highcost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based on market share, and the medical device excisetax on non-exempt medical devices. Further, the Bipartisan Budget Act of 2018, or the BBA, among other things, amends the ACA, effective January 1, 2019,to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole.” We continue to evaluate how the ACA and recent efforts torepeal and replace or limit the implementation of the ACA will impact our business.In addition, other legislative changes have been proposed and adopted since the ACA was enacted. For example, in August 2011, President Obama signedinto law the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congressproposals in spending reductions. The Joint Select Committee did not achieve a targeted deficit reduction of an amount greater than $1.2 trillion for the years2013 through 2021, triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions to Medicarepayments to healthcare providers of up to 2.0% per fiscal year, which started in 2013 and, due to subsequent legislative amendments to the statute, includingthe BBA, will stay in effect through 2027 unless additional Congressional action is taken. In January 2013, President Obama signed into law the AmericanTaxpayer Relief Act of 2012, which, among other things, reduced Medicare payments to several categories of healthcare providers and increased the statuteof limitations period for the government to recover overpayments to providers from three to five years. Additionally, there have been several recent U.S. Congressional inquiries and proposed and enacted legislation at the federal and state levels designed to,among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost ofdrugs under Medicare, and reform government program reimbursement methodologies for drugs. At the federal level, the U.S. House of Representativesformed an Affordable Drug Pricing Task Force to advance legislation intended to control pharmaceutical drug costs and investigate pharmaceutical drugpricing, and the U.S. Senate requested information from certain pharmaceutical companies in connection with an investigation into pharmaceutical drugpricing practices. Further, the Trump Administration’s budget proposal for fiscal year 2019 contains further drug price control measures that could be enactedduring the 2019 budget process or in other future legislation, including, for example, measures to permit Medicare Part D plans to negotiate the price ofcertain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid, and to eliminate cost sharing for generic drugs for low-income patients. While any proposed measures will require authorization through additional legislation to become effective, Congress and the TrumpAdministration have both stated that it will continue to seek new legislative and/or administrative measures to control drug costs. At the state level,legislatures have been increasingly passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing,including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparencymeasures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. If healthcare policies or reforms intended to curbhealthcare costs are adopted, or if we experience negative publicity with respect to the pricing of our products or the pricing of pharmaceutical drugsgenerally, the prices that we charge for any approved products may be limited, our commercial opportunity may be limited and/or our revenues from sales ofour products may be negatively impacted.If we obtain regulatory approval and commercialization of MitoGel, VesiGel or any of our other product candidates, these laws may result in additionalreductions in healthcare funding, which could have an adverse effect on our customers and accordingly, our financial operations. Legislative and regulatoryproposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. We cannot be surewhether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact ofsuch changes on the marketing approvals of MitoGel, VesiGel or our other product candidates may be.Although we cannot predict the full effect on our business of the implementation of existing legislation or the enactment of additional legislation pursuant tohealthcare and other legislative reform, we believe that legislation or regulations that would reduce reimbursement for, or restrict coverage of, our productscould adversely affect how much or under what circumstances healthcare providers will prescribe or administer our products. This could adversely affect ourbusiness by reducing our ability to generate revenues, raise capital, obtain additional licensees and market our products. In addition, we believe theincreasing emphasis on managed care in the United States has and will continue to put pressure on the price and usage of pharmaceutical products, whichmay adversely impact product sales.30 We may be unable to obtain Orphan Drug Designation or exclusivity for future product candidates we may develop. If our competitors are able to obtainorphan drug exclusivity for their products that are for the same indication as our product candidates, we may not be able to have competing productsapproved by the applicable regulatory authority for a significant period of time.Under the Orphan Drug Act of 1983, the FDA may designate a product as an orphan drug if it is intended to treat an orphan disease or condition, defined as apatient population of fewer than 200,000 in the United States, or a patient population greater than 200,000 in the United States where there is no reasonableexpectation that the cost of developing the drug will be recovered from sales in the United States.In the United States, Orphan Drug Designation entitles a party to financial incentives, such as opportunities for grant funding towards clinical trial costs, taxadvantages and user-fee waivers. In addition, if a product receives the first FDA approval for the indication for which it has Orphan Drug Designation, theproduct is entitled to orphan drug exclusivity, which means the FDA may not approve any other application to market the same drug for the same indicationfor a period of seven years, except in limited circumstances, such as a showing of clinical superiority over the product with orphan exclusivity or where themanufacturer is unable to assure sufficient product quantity.Although the FDA has granted MitoGel orphan drug designation for the treatment of UTUC and to Vesimune for treatment of CIS, we may not receive orphandrug designation for any of our other product candidates. If our competitors are able to obtain orphan drug exclusivity for their products that are the same orsimilar to our product candidates before our drug candidates are approved, we may not be able to have competing product candidates approved by the FDAfor a significant period of time. Any delay in our ability to bring our product candidates to market would negatively impact our business, revenue, cash flowsand operations.Orphan Drug Designation may not ensure that we will enjoy market exclusivity in a particular market, and if we fail to obtain or maintain orphan drugexclusivity for our product candidates, we may be subject to earlier competition and our potential revenue will be reduced.Orphan Drug Designation entitles a party to financial incentives, such as opportunities for grant funding towards clinical trial costs, tax advantages, user-feewaivers and market exclusivity for certain periods of time.MitoGel and Vesimune have been granted Orphan Drug Designation for the treatment of UTUC and CIS, respectively, in the United States. Even if we obtainOrphan Drug Designation for our other product candidates, we may not be the first to obtain regulatory approval for any particular orphan indication due tothe uncertainties associated with developing biopharmaceutical products. Further, even if we obtain Orphan Drug Designation for a product candidate, thatexclusivity may not effectively protect the product from competition because different drugs with different active moieties can be approved for the samecondition. In addition, if a competitor obtains approval and marketing exclusivity for a drug product with an active moiety that is the same as that in aproduct candidate we are pursuing for the same indication, approval of our product candidate would be blocked during the period of marketing exclusivityunless we could demonstrate that our product candidate is clinically superior to the approved product. In addition, if a competitor obtains approval andmarketing exclusivity for a drug product with an active moiety that is the same as that in a product candidate we are pursuing for a different orphanindication, this may negatively impact the market opportunity for our product candidate. There have been legal challenges to aspects of the FDA’sregulations and policies concerning the exclusivity provisions of the Orphan Drug Act, and future challenges could lead to changes that affect theprotections afforded our product candidates in ways that are difficult to predict.Even if we receive regulatory approval for our product candidates, we will be subject to ongoing regulatory obligations and continued regulatory review,which may result in significant additional expenses, limit or withdraw regulatory approval and subject us to penalties if we fail to comply with applicableregulatory requirements.If and when regulatory approval has been granted, our product candidates or any approved product will be subject to continual regulatory review by the FDAand/or non-U.S. regulatory authorities. Additionally, any product candidates, if approved, will be subject to extensive and ongoing regulatory requirements,including labeling and other restrictions and market withdrawal and we may be subject to penalties if we fail to comply with regulatory requirements orexperience unanticipated problems with our products.Any regulatory approvals that we receive for our product candidates may also be subject to limitations on the approved indications for which the productmay be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase 4 clinical trials, andsurveillance to monitor the safety and efficacy of the product. In addition, if the applicable regulatory agency approves our product candidates, themanufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the product willbe subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information andreports, registration, as well as continued compliance with cGMP and GCP for any clinical trials that we conduct post-approval.31 Later discovery of previously unknown problems with our product candidates, including adverse events of unanticipated severity or frequency, or problemswith our third-party manufacturers’ processes, or failure to comply with regulatory requirements, may result in, among other things: •restrictions on the marketing or manufacturing of the product, withdrawal of the product from the market, or voluntary or mandatory productrecalls; •fines, warning letters or holds on clinical trials •refusal by the FDA to approve pending applications or supplements to approved applications submitted by us, or suspension or revocation ofproduct license approvals; and •product seizure or detention, or refusal to permit the import or export of products; and injunctions or the imposition of civil or criminal penalties.Our ongoing regulatory requirements may also change from time to time, potentially harming or making costlier our commercialization efforts. We cannotpredict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States orother countries. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able tomaintain regulatory compliance, we may lose any marketing approval that we may have obtained, and we may not achieve or sustain profitability, whichwould adversely affect our business.Our relationships with healthcare professionals, independent contractors, clinical investigators, CROs, consultants and vendors in connection with ourcurrent and future business activities may be subject to federal and state healthcare fraud and abuse laws, false claims laws, transparency laws,government price reporting, and health information privacy and security laws. If we are unable to comply, or have not fully complied, with such laws, wecould face penalties.We may currently be or may become subject to various U.S. federal and state health care laws, including those intended to prevent health care fraud andabuse.The federal Anti-Kickback Statute prohibits, among other things, persons or entities from knowingly and willfully soliciting, offering, receiving or payingany remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward, or in return for,either the referral of an individual for, or the purchase, lease, order or recommendation of, any good, facility, item or service, for which payment may be made,in whole or in part, by a federal healthcare program such as Medicare and Medicaid. Remuneration has been broadly defined to include anything of value,including, but not limited to, cash, improper discounts, and free or reduced-price items and services.Federal false claims laws, including the federal False Claims Act, or FCA, and civil monetary penalties law impose penalties against individuals or entitiesfor, among other things, knowingly presenting, or causing to be presented, to the federal government, claims for payment or approval that are false orfraudulent or making a false record or statement to avoid, decrease or conceal an obligation to pay money to the federal government. The FCA has been usedto, among other things, prosecute persons and entities submitting claims for payment that are inaccurate or fraudulent, that are for services not provided asclaimed, or for services that are not medically necessary. The FCA includes a whistleblower provision that allows individuals to bring actions on behalf of thefederal government and share a portion of the recovery of successful claims.Many states have similar fraud and abuse statutes and regulations that may be broader in scope and may apply regardless of payor, in addition to items andservices reimbursed under Medicaid and other state programs. State and federal authorities have aggressively targeted medical technology companies for,among other things, alleged violations of these anti-fraud statutes, based on unlawful financial inducements paid to prescribers and beneficiaries, as well asimpermissible promotional practices, including certain marketing arrangements that rely on volume-based pricing and off-label promotion of FDA-approvedproducts.The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, among other things, imposes criminal liability for knowingly andwillfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including public and private payors, or knowingly andwillfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment forhealthcare benefits, items or services.Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their implementingregulations, impose, among other things, specified requirements on covered entities and their business associates relating to the privacy and, security andtransmission of individually identifiable health information, including mandatory contractual terms and required implementation of certain safeguards ofsuch information. Among other things, HITECH makes HIPAA’s security standards directly applicable to business associates, independent contractors oragents of covered entities that receive or obtain32 protected health information in connection with providing a service on behalf of a covered entity. HITECH also created four new tiers of civil monetarypenalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority tofile civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuingfederal civil actions. In addition, state laws govern the privacy and security of health information in some circumstances, many of which differ from eachother in significant ways, may not have the same effect and may not be preempted by HIPAA, thus complicating compliance efforts.Our operations will also be subject to the federal Open Payments program pursuant to the Physician Payments Sunshine Act, created under Section 6002 ofthe ACA and its implementing regulations, which requires certain manufacturers of drugs, devices, biologicals and medical supplies for which payment isavailable under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific exceptions, to annually report to the Centers for Medicare &Medicaid Services, or CMS, an agency within the U.S. Department of Health and Human Services, or HHS, information related to payments and other transfersof value provided to physicians and teaching hospitals and certain ownership and investment interests held by physicians and their immediate familymembers. We may also be subject to state laws that require drug manufacturers to report information related to payments and other transfers of value tophysicians and other healthcare providers or marketing expenditures, and/or state laws that require pharmaceutical companies to comply with thepharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidelines promulgated by the federal government.Many states have also adopted laws similar to each of the above federal laws, which may be broader in scope and apply to items or services reimbursed byany payor, including commercial insurers. If any of our business activities, including but not limited to our relationships with healthcare providers, are foundto violate any of the aforementioned laws, we may be subject to administrative, civil and/or criminal penalties, damages, monetary fines, disgorgement,individual imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages,reputational harm, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolveallegations of non-compliance with these laws, diminished profits and future earnings and curtailment or restructuring of our operations.Also, the U.S. Foreign Corrupt Practices Act and similar worldwide anti-bribery laws generally prohibit companies and their intermediaries from makingimproper payments to non-U.S. officials for the purpose of obtaining or retaining business. We cannot assure you that our internal control policies andprocedures will protect us from reckless or negligent acts committed by our employees, future distributors, partners, collaborators or agents.Violations ofthese laws, or allegations of such violations, could result in fines, penalties or prosecution and have a negative impact on our business, results of operationsand reputation.Legislative or regulatory healthcare reforms in the United States or abroad may make it more difficult and costly for us to obtain regulatory clearance orapproval of our product candidates or any future product candidates and to produce, market, and distribute our products after clearance or approval isobtained.From time to time, legislation is drafted and introduced in Congress in the United States or by governments in foreign jurisdictions that could significantlychange the statutory provisions governing the regulatory clearance or approval, manufacture, and marketing of regulated products or the reimbursementthereof. In addition, FDA or foreign regulatory agency regulations and guidance are often revised or reinterpreted by the FDA or the applicable foreignregulatory agency in ways that may significantly affect our business and our products. Any new regulations or revisions or reinterpretations of existingregulations may impose additional costs or lengthen review times of our product candidates or any future product candidates. We cannot determine whateffect changes in regulations, statutes, legal interpretation or policies, when and if promulgated, enacted or adopted may have on our business in the future.Such changes could, among other things, require: •changes to manufacturing methods; •recall, replacement, or discontinuance of one or more of our products; and •additional recordkeeping.Each of these would likely entail substantial time and cost and could harm our business and our financial results. In addition, delays in receipt of or failure toreceive regulatory clearances or approvals for any future products would harm our business, financial condition, and results of operations.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 couldnegatively impact our business.We are 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. Our operations involve the use of hazardous and flammable materials, including chemicalsand biological materials. Our operations also produce hazardous waste products. We33 generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or injury from thesematerials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, and anyliability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties.We maintain workers compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use ofhazardous materials or other work-related injuries with policy limits that we believe are customary for similarly situated companies and adequate to provideus with coverage for foreseeable risks. Although we maintain such insurance, this insurance may not provide adequate coverage against potential liabilities.In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current orfuture laws and regulations may impair our research, development or production efforts. Failure to comply with these laws and regulations also may result insubstantial fines, penalties or other sanctions.It may be difficult for us to profitably sell our product candidates if coverage and reimbursement for these products is limited by government authoritiesand/or third-party payor policies.In addition to any healthcare reform measures which may affect reimbursement, market acceptance and sales of MitoGel, VesiGel and our other productcandidates, if approved, will depend on the coverage and reimbursement policies of third-party payors, like government authorities, private health insurers,and managed care organizations. Third-party payors decide which medications they will cover and separately establish reimbursement levels.A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government and other third-party payors are increasingly challenging theprices charged for health care products, examining the cost effectiveness of drugs in addition to their safety and efficacy, and limiting or attempting to limitboth coverage and the level of reimbursement for prescription drugs. We cannot be sure that coverage will be available for MitoGel, VesiGel or our otherproduct candidates, if approved, or, if coverage is available, the level of reimbursement will be adequate to make our products affordable for patients orprofitable for us.There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products. In the United States, decisions aboutreimbursement for new medicines under Medicare are made by CMS, as the administrator for the Medicare program. Private payors often use CMS as a modelfor their coverage and reimbursement decisions. It is difficult to predict what CMS as well as other payors will decide with respect to reimbursement forfundamentally novel products such as ours, as there is no body of established practices and precedents for these new products.Reimbursement may impact the demand for, and/or the price of, any product for which we obtain marketing approval. Assuming we obtain coverage for agiven product by a third-party payor, the resulting reimbursement payment rates may not be adequate or may require co-payments that patients findunacceptably high. Patients who are prescribed medications for the treatment of their conditions, and their prescribing physicians, generally rely on third-party payors to reimburse all or part of the costs associated with their prescription drugs. Patients are unlikely to use our products unless coverage is provided,and reimbursement is adequate to cover all or a significant portion of the cost of our products. Therefore, coverage and adequate reimbursement is critical tonew product acceptance. Coverage decisions may depend upon clinical and economic standards that disfavor new drug products when more established orlower cost therapeutic alternatives are already available or subsequently become available. There may be significant delays in obtaining coverage andreimbursement for newly approved drugs, and coverage may be more limited than the purposes for which the drug is approved by the FDA or comparableforeign regulatory authorities. Moreover, eligibility for coverage and reimbursement does not imply that a drug will be paid for in all cases or at a rate thatcovers our costs, including research, development, manufacture, sale and distribution.Reimbursement by a third-party payor may depend upon a number of factors including the third-party payor’s determination that use of a product is: •a covered benefit under its health plan; •safe, effective and medically necessary; •appropriate for the specific patient; •cost-effective; and •neither experimental nor investigational.Obtaining coverage and reimbursement approval for a product from a government or other third-party payor is a time-consuming and costly process thatcould require us to provide supporting scientific, clinical and cost effectiveness data for the use of our products to the payor. Further, no uniform policyrequirement for coverage and reimbursement for drug products exists among third-party payors34 in the United States. Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor. As a result, the coveragedetermination process may require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance thatcoverage and adequate reimbursement will be applied consistently or obtained in the first instance. We may not be able to provide data sufficient to gainacceptance with respect to coverage and/or sufficient reimbursement levels. We cannot be sure that coverage or adequate reimbursement will be available forMitoGel, VesiGel or any of our other product candidates, if approved. Also, we cannot be sure that reimbursement amounts will not reduce the demand for, orthe price of, our future products. If reimbursement is not available, or is available only to limited levels, we may not be able to commercialize MitoGel,VesiGel or our other product candidates, or achieve profitably at all, even if approved.Legislative or regulatory healthcare reforms in the United States may make it more difficult and costly for us to obtain regulatory clearance or approval ofMitoGel, VesiGel or any of our other product candidates and to produce, market, and distribute our products after clearance or approval is obtained.From time to time, legislation is drafted and introduced in Congress that could significantly change the statutory provisions governing the regulatoryclearance or approval, manufacture, and marketing of regulated products or the reimbursement thereof. In addition, FDA regulations and guidance are oftenrevised or reinterpreted by the FDA in ways that may significantly affect our business and our products. Any new regulations or revisions or reinterpretationsof existing regulations may impose additional costs or lengthen review times of MitoGel, VesiGel or any of our other product candidates. We cannotdetermine what effect changes in regulations, statutes, legal interpretation or policies, when and if promulgated, enacted or adopted may have on our businessin the future. Such changes could, among other things, require: •changes to manufacturing methods; •change in protocol design; •additional treatment arm (control); •recall, replacement, or discontinuance of one or more of our products; and •additional recordkeeping.Each of these would likely entail substantial time and cost and could harm our business and our financial results.Risks Related to Ownership of Our Ordinary SharesThe market price of our ordinary shares has been and may continue to be subject to fluctuation and you could lose all or part of your investment.The stock market in general has been, and the market price of our ordinary shares in particular has been and may continue to be, subject to fluctuation,whether due to, or irrespective of, our operating results and financial condition. The market price of our ordinary shares on the Nasdaq Global Market mayfluctuate as a result of a number of factors, some of which are beyond our control, including, but not limited to: •actual or anticipated variations in our and our competitors’ results of operations and financial condition; •physician and market acceptance of our products; •the mix of products that we sell; •our success or failure to obtain approval for and commercialize our product candidates; •changes in earnings estimates or recommendations by securities analysts, if our ordinary shares are covered by analysts; •development of technological innovations or new competitive products by others; •announcements of technological innovations or new products by us; •publication of the results of preclinical or clinical trials for MitoGel, VesiGel or our other product candidates; •failure by us to achieve a publicly announced milestone; •delays between our expenditures to develop and market new or enhanced product candidates and the generation of sales from those products; •developments concerning intellectual property rights, including our involvement in litigation brought by or against us;35 •regulatory developments and the decisions of regulatory authorities as to the approval or rejection of new or modified products; •changes in the amounts that we spend to develop, acquire or license new products, technologies or businesses; •changes in our expenditures to promote our products; •our sale or proposed sale, or the sale by our significant shareholders, of our ordinary shares or other securities in the future; •changes in key personnel; •success or failure of our research and development projects or those of our competitors; •the trading volume of our ordinary shares; and •general economic and market conditions and other factors, including factors unrelated to our operating performance.These factors and any corresponding price fluctuations may negatively impact the market price of our ordinary shares and result in substantial losses beingincurred by our investors. In the past, following periods of market volatility, public company shareholders have often instituted securities class actionlitigation. If we were to become involved in securities litigation, it could impose a substantial cost upon us and divert the resources and attention of ourmanagement from our business.If equity research analysts do not publish research or reports about our business or if they issue unfavorable commentary or downgrade our ordinaryshares, the price of our ordinary shares could decline.The trading market for our ordinary shares relies in part on the research and reports that equity research analysts publish about us and our business, if at all.We do not have control over these analysts and we do not have commitments from them to write research reports about us. The price of our ordinary sharescould decline if no research reports are published about us or our business, or if one or more equity research analysts downgrade our ordinary shares or ifthose analysts issue other unfavorable commentary or cease publishing reports about us or our business.Future sales of our ordinary shares could reduce the market price of our ordinary shares.If our existing shareholders, particularly our directors, their affiliates, or our executive officers, sell a substantial number of our ordinary shares in the publicmarket, the market price of our ordinary shares could decrease significantly. The perception in the public market that our shareholders might sell our ordinaryshares could also depress the market price of our ordinary shares and could impair our future ability to obtain capital, especially through an offering of equitysecurities.As of the date of this annual report, the holders of approximately 4,515,674 ordinary shares are entitled to registration rights. In addition, our sale ofadditional ordinary shares or similar securities in order to raise capital might have a similar negative impact on the share price of our ordinary shares. Adecline in the price of our ordinary shares might impede our ability to raise capital through the issuance of additional ordinary shares or other equitysecurities and may cause you to lose part or all of your investment in our ordinary shares.The significant share ownership position of our officers, directors and entities affiliated with certain of our directors may limit your ability to influencecorporate matters.Our officers, directors and entities affiliated with certain of our directors beneficially own or control, directly or indirectly, approximately 24.4% of ouroutstanding ordinary shares. Accordingly, these persons are able to significantly influence, though not independently determine, the outcome of mattersrequired to be submitted to our shareholders for approval, including decisions relating to the election of our board of directors, and the outcome of anyproposed merger or consolidation of our company. These interests may not be consistent with those of our other shareholders. In addition, these persons’significant interest in us may discourage third parties from seeking to acquire control of us, which may adversely affect the market price of our ordinaryshares.We have never paid cash dividends on our share capital, and we do not anticipate paying any cash dividends in the foreseeable future.We have never declared or paid cash dividends on our share capital, nor do we anticipate paying any cash dividends on our share capital in the foreseeablefuture. We currently intend to retain all available funds and any future earnings to fund the development and growth of our business. As a result, capitalappreciation, if any, of our ordinary shares will be investors’ sole source of gain for the foreseeable future. In addition, Israeli law limits our ability to declareand pay dividends and may subject our dividends to Israeli withholding taxes.36 If we are classified as a passive foreign investment company, our U.S. shareholders may suffer adverse tax consequences.Generally, for any taxable year, if at least 75% of our gross income is passive income, or at least 50% of the value of our assets is attributable to assets thatproduce passive income or are held for the production of passive income, including cash, we would be characterized as a passive foreign investmentcompany, or PFIC, for U.S. federal income tax purposes. We do not believe that we were classified as a PFIC for the taxable year ended December 31, 2017.However, based upon the expected nature and composition of our income and assets, we anticipate that we will be classified as a PFIC for the taxable yearending December 31, 2018. For purposes of these tests, passive income includes dividends, interest gains from commodities and securities transactions, theexcess of gains over losses from the disposition of assets which produce passive income (including amounts derived by reason of the temporary investment offunds raised in offerings of our shares) and rents and royalties other than rents and royalties which are received from unrelated parties in connection with theactive conduct of a trade or business. If we are characterized as a PFIC, our U.S. shareholders may suffer adverse tax consequences, including having gainsrealized on the sale of our ordinary shares treated as ordinary income, rather than capital gain, the loss of the preferential rate applicable to dividends receivedon our ordinary shares by individuals who are U.S. holders, and having interest charges apply to distributions by us and gains from the sales of our shares.Our status as a PFIC will depend on the nature and composition of our income and the nature, composition and value of our assets (which may be determinedbased on the fair market value of each asset, with the value of goodwill and going concern value determined in large part by reference to the market value ofour common shares, which may be volatile) from time to time. We cannot provide any assurances regarding our PFIC status for the current or future taxableyears, and our U.S. tax counsel has not provided any opinion regarding our PFIC status.We do not currently intend to provide the information necessary for our U.S. shareholders to make QEF elections.As a foreign private issuer, we are permitted, and intend, to follow certain home country corporate governance practices instead of otherwise applicableNasdaq requirements, and we will not be subject to certain U.S. securities laws including, but not limited to, U.S. proxy rules and the filing of certainExchange Act reports.As a foreign private issuer, we are permitted to and follow certain home country corporate governance practices instead of those otherwise required by theNasdaq Stock Market for domestic U.S. issuers. Following our home country governance practices as opposed to the requirements that would otherwise applyto a U.S. company listed on the Nasdaq Global Market may provide less protection to you than what is accorded to investors under the Nasdaq Rulesapplicable to domestic U.S. issuers.As a foreign private issuer, we are exempt from the rules and regulations under the Securities Exchange Act of 1934, or the Exchange Act, related to thefurnishing and content of proxy statements, including the requirement to disclose the compensation of our Chief Executive Officer, Chief Financial Officer,President of Israel Operations and the other two most highly compensated executive officers on an individual basis. Nevertheless, pursuant to regulationspromulgated under the Israeli Companies Law, 5759-1999, or the Israeli Companies Law, we are required to disclose the annual compensation of our fivemost highly compensated office holders on an individual basis. Such disclosure is not as extensive as that required of a U.S. domestic issuer. Our officers,directors and principal shareholders are also exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the ExchangeAct. In addition, we are not required under the Exchange Act to file reports and financial statements with the SEC as frequently or as promptly as U.S.domestic companies whose securities are registered under the Exchange Act and we are exempt from filing quarterly reports with the SEC under the ExchangeAct. Moreover, we are not required to comply with Regulation FD, which restricts the selective disclosure of material information, although we havevoluntarily adopted a corporate disclosure policy substantially similar to Regulation FD. These exemptions and leniencies will reduce the frequency andscope of information and protections to which you may otherwise have been eligible in relation to a U.S. domestic issuer.Loss of foreign private issuer status in the future could result in significantly increased costs and divert management attention.We would lose our foreign private issuer status if a majority of our shares are owned by U.S. residents and a majority of our directors or executive officers areU.S. citizens or residents or we fail to meet additional requirements necessary to avoid loss of foreign private issuer status. However, we cannot assure youthat at June 30, 2018, the next determination date of our foreign private issuer status, we will qualify as a foreign private issuer. If we cease to qualify as aforeign private issuer at this determination date, we will be required to begin reporting as a domestic issuer on January 1, 2019. The regulatory andcompliance costs to us under U.S. securities laws as a U.S. domestic issuer may be significantly higher. If we are not a foreign private issuer, we will berequired to file periodic reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive than the formsavailable to a foreign private issuer. We may also be required to modify certain of our policies to comply with accepted governance practices associated withU.S. domestic issuers. Such conversion and modifications will involve additional costs. In addition, we would lose our ability to rely upon exemptions fromcertain corporate governance requirements on U.S. stock exchanges that are available to foreign private issuers.37 We are an emerging growth company and the reduced disclosure requirements applicable to emerging growth companies may make our ordinary sharesless attractive to investors.We are an emerging growth company, as defined in the JOBS Act, and we may take advantage of certain exemptions from various requirements that areapplicable to other public companies that are not emerging growth companies.For as long as we remain an emerging growth company we are permitted and intend to rely on exemptions from certain disclosure requirements that areapplicable to other public companies that are not “emerging growth companies.” These exemptions include: •not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting; •not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regardingmandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financialstatements; •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 will remain an emerging growth company until the earliest of: (i) the last day of our fiscal year during which we have total annual gross revenues of atleast $1.07 billion; (ii) the last day of our fiscal year following the fifth anniversary of the closing of our initial public offering; (iii) the date on which wehave, during the previous three-year period, issued more than $1.0 billion in non-convertible debt; or (iv) the date on which we are deemed to be a “largeaccelerated filer” under the Exchange Act. We have opted out of the extended transition period made available to emerging growth companies to complywith newly adopted public company accounting requirements.When we are no longer deemed to be an emerging growth company, we will not be entitled to the exemptions provided in the JOBS Act discussed above. Wecannot predict if investors will find our ordinary shares less attractive as a result of our reliance on exemptions under the JOBS Act. If some investors find ourordinary shares less attractive as a result, there may be a less active trading market for our ordinary shares and our share price may be more volatile.Risks Related to our Operations in IsraelOur headquarters, research and development and other significant operations are located in Israel and, therefore, our results may be adversely affected bypolitical, economic and military instability in Israel.Our headquarters and research and development facilities are located in Ra’anana, Israel. In addition, the majority of our key employees are residents of Israel.If these or any future facilities in Israel were to be damaged, destroyed or otherwise unable to operate, whether due to war, acts of hostility, earthquakes, fire,floods, hurricanes, storms, tornadoes, other natural disasters, employee malfeasance, terrorist acts, power outages or otherwise, or if performance of ourresearch and development is disrupted for any other reason, such an event could delay our clinical trials or, if our product candidates are approved and wechoose to manufacture all or any part of them internally, jeopardize our ability to manufacture our products as promptly as our prospective customers willlikely expect, or possibly at all. If we experience delays in achieving our development objectives, or if we are unable to manufacture an approved productwithin a timeframe that meets our prospective customers’ expectations, our business, prospects, financial results and reputation could be harmed.Political, economic and military conditions in Israel may directly affect our business. Since the establishment of the State of Israel in 1948, a number of armedconflicts have taken place between Israel and its neighboring countries, Hamas (an Islamist militia and political group that controls the Gaza Strip) andHezbollah (an Islamist militia and political group based in Lebanon). In addition, several countries, principally in the Middle East, restrict doing businesswith Israel, and additional countries may impose restrictions on doing business with Israel and Israeli companies whether as a result of hostilities in the regionor otherwise. Any hostilities involving Israel, terrorist activities, political instability or violence in the region or the interruption or curtailment of trade ortransport between Israel and its trading partners could adversely affect our operations and results of operations and adversely affect the market price of ourordinary shares.Our commercial insurance does not cover losses that may occur as a result of an event associated with the security situation in the Middle East. Although theIsraeli government is currently committed to covering the reinstatement value of direct damages that are caused by terrorist attacks or acts of war, there can beno assurance that this government coverage will be maintained, or if38 maintained, will be sufficient to compensate us fully for damages incurred. Any losses or damages incurred by us could have a material adverse effect on ourbusiness, financial condition and results of operations.Further, our operations could be disrupted by the obligations of our employees to perform military service. As of December 31, 2017, we had 36 employeesbased in Israel. Of these employees, some may be military reservists, and may be called upon to perform military reserve duty of up to 36 days per year (and insome cases more) until they reach the age of 40 (and in some cases, up to the age of 45 or older). Additionally, they may be called to active duty at any timeunder emergency circumstances. In response to increased tension and hostilities in the region, there have been, at times, call-ups of military reservists, and itis possible that there will be additional call-ups in the future. Our operations could be disrupted by the absence of these employees due to military service.Such disruption could harm our business and operating results.The Israeli government grants we have received for research and development activities restrict our ability to manufacture products and transfertechnologies outside of Israel and require us, in addition to the payment of royalties, to satisfy specified conditions. If we fail to satisfy these conditions, wemay be required to refund grants previously received and incur financial penalties.We have received grants under the Israeli Law for the Encouragement of Industrial Research, Development and Technological Innovation, 5754-1984, or theR&D Law, from the Israel Innovation Authority in Israel, or the IIA, formerly known as the Office of the Chief Scientist of the Ministry of Economy andIndustry, an independent and impartial public entity, for some of our development programs. Through December 31, 2017, we had received grants in theaggregate amount of $2.1 million. We may in the future apply to receive additional grants from the IIA. However, we cannot predict whether we will beentitled to any future grants, or the amounts of any such grants.A recipient of a grant from the IIA is obligated to pay royalties generally at a rate of 3% to 5% on revenues from sales of products developed with IIA-fundedtechnology, up to the amount of the grant related to any such products plus accrued interest. Under the R&D Law, a company that received grants from theIIA may not transfer IIA-funded technology or manufacture products developed with IIA-funded technology outside of the State of Israel without firstobtaining the approval of the IIA. For example, under the Allergan Agreement, Allergan has the option to manufacture products developed with IIA-fundedtechnology outside of Israel and, although Allergan has not yet exercised this option, we have requested approval from the IIA for a possible transfer and arecurrently awaiting their response. We may not receive any such approval upon any request, which could prevent us, for example, from out-licensing ourproduct candidates or complying with our existing agreements. Even if we do receive such approvals, we may be required to pay increased royalties of up to300% of the amount of the original grant and other amounts. If we do not receive such approvals, we may be required to pay significant penalties.In June 2017, new rules published by the IIA for granting a right to use know- how developed from research and development that was conducted pursuant toa plan approved by the IIA outside of Israel, or Licensing Rules, came into effect. The Licensing Rules allow a recipient of a grant from the IIA to grant thirdparties outside of Israel the right to use know-how, or License, provided that the IIA authorized the grant of the License. In such case, the recipient of thegrant has to pay the IIA for the License. The amount of payment is based on various factors, including the consideration received by the licensor and, inaccordance with the formulas set forth in the Licensing Rules, may equal up to six times the IIA-funding amount plus interest. When the consideration for thegrant includes nonmonetary compensation or monetary compensation that is not fixed, or when a “special relationship” exists between the licensor andlicensee (e.g., when a party controls the other party or is the other party’s exclusive distributor) or when the agreed consideration does not reflect, in the IIA’sopinion, the market value, the IIA may base the value of the transaction on an economic assessment that it obtains for such purpose.The IIA may also impose certain conditions on any arrangement under which it permits us to transfer IIA-funded technology outside of the State of Israel.Furthermore, the consideration available to our shareholders in a transaction involving the transfer outside of the State of Israel of IIA-funded technology(such as a merger or similar transaction) may be reduced by any amounts that we are required to pay to IIA. The restrictions under the R&D Law will continueto apply even after we have repaid the full amount of royalties due to the IIA. If we fail to satisfy the conditions of the R&D Law, we may be required torefund the amounts of the grants previously received, together with interest and penalties, and may become subject to criminal charges.Provisions of Israeli law and our articles of association may delay, prevent or otherwise impede a merger with, or an acquisition of, us, even when theterms of such a transaction are favorable to us and our shareholders.Israeli corporate law regulates mergers, requires tender offers for acquisitions of shares above specified thresholds, requires special approvals for transactionsinvolving directors, officers or significant shareholders and regulates other matters that may be relevant to such types of transactions. For example, a tenderoffer for all of a company’s issued and outstanding shares can only be completed if shareholders not accepting the tender offer hold less than 5% of the issuedshare capital. Completion of the tender offer also requires approval of a majority of the offerees that do not have a personal interest in the tender offer, unlessshareholders not accepting the39 tender offer hold less than 2% of the company’s outstanding shares. Furthermore, the shareholders, including those who indicated their acceptance of thetender offer, may, at any time within six months following the completion of the tender offer, petition an Israeli court to alter the consideration for theacquisition, unless the acquirer stipulated in its tender offer that a shareholder that accepts the offer may not seek such appraisal rights.Furthermore, Israeli tax considerations may make potential transactions unappealing to us or to our shareholders whose country of residence does not have atax treaty with Israel exempting such shareholders from Israeli tax. For example, Israeli tax law does not recognize tax-free share exchanges to the same extentas U.S. tax law. With respect to mergers, Israeli tax law allows for tax deferral in certain circumstances but makes the deferral contingent on the fulfillment of anumber of conditions, including, in some cases, a holding period of two years from the date of the transaction during which sales and dispositions of shares ofthe participating companies are subject to certain restrictions. Moreover, with respect to certain share swap transactions, the tax deferral is limited in time, andwhen such time expires, the tax becomes payable even if no disposition of the shares has occurred. These provisions could delay, prevent or impede anacquisition of us or our merger with another company, even if such an acquisition or merger would be beneficial to us or to our shareholders.It may be difficult to enforce a judgment of a U.S. court against us, our officers and directors or the Israeli experts named in this annual report in Israel orthe United States, to assert U.S. securities laws claims in Israel or to serve process on our officers and directors and these experts.We are incorporated in Israel. Several of our directors and executive officers listed in this annual report reside outside of the United States, and most of ourassets and most of the assets of these persons are located outside of the United States. Therefore, a judgment obtained against us, or any of these persons,including a judgment based on the civil liability provisions of the U.S. federal securities laws, may not be collectible in the United States and may not beenforced by an Israeli court. It may also be difficult for you to effect service of process on these persons in the United States or to assert U.S. securities lawclaims in original actions instituted in Israel. Israeli courts may refuse to hear a claim based on an alleged violation of U.S. securities laws reasoning thatIsrael is not the most appropriate forum in which to bring such a claim. In addition, even if an Israeli court agrees to hear a claim, it may determine that Israelilaw and not U.S. law is applicable to the claim. If U.S. law is found to be applicable, the content of applicable U.S. law must be proven as a fact by expertwitnesses, which can be a time consuming and costly process. Certain matters of procedure will also be governed by Israeli law.There is little binding case law in Israel that addresses the matters described above. As a result of the difficulty associated with enforcing a judgment againstus in Israel, you may not be able to collect any damages awarded by either a U.S. or foreign court.Your rights and responsibilities as a shareholder will be governed by Israeli law, which differs in some material respects from the rights andresponsibilities of shareholders of U.S. companies.The rights and responsibilities of the holders of our ordinary shares are governed by our articles of association and by Israeli law. These rights andresponsibilities differ in some material respects from the rights and responsibilities of shareholders in U.S. companies. In particular, a shareholder of an Israelicompany has a duty to act in good faith and in a customary manner in exercising its rights and performing its obligations towards the company and othershareholders, and to refrain from abusing its power in the company, including, among other things, in voting at a general meeting of shareholders on matterssuch as amendments to a company’s articles of association, increases in a company’s authorized share capital, mergers and acquisitions and related partytransactions requiring shareholder approval, as well as a general duty to refrain from discriminating against other shareholders. In addition, a shareholder whois aware that it possesses the power to determine the outcome of a vote at a meeting of the shareholders or to appoint or prevent the appointment of a directoror executive officer in the company has a duty of fairness toward the company.There is limited case law available to assist us in understanding the nature of these duties or the implications of these provisions. These provisions may beinterpreted to impose additional obligations and liabilities on holders of our ordinary shares that are not typically imposed on shareholders of U.S.companies.Risks Related to Our Management and EmployeesWe depend on our executive officers and key clinical and technical personnel to operate our business effectively, and we must attract and retain highlyskilled employees in order to succeed.Our success depends upon the continued service and performance of our executive officers who are essential to our growth and development. The loss of oneor more of our executive officers could delay or prevent the continued successful implementation of our growth strategy, could affect our ability to manageour company effectively and to carry out our business plan, or could otherwise be detrimental to us. As of December 31, 2017, we had 42 full-time employees.Therefore, knowledge of our product candidates and clinical trials is concentrated among a small number of individuals. Members of our executive team aswell as key clinical, scientific40 and technical personnel may resign at any time and there can be no assurance that we will be able to continue to retain such personnel. If we cannot recruitsuitable replacements in a timely manner, our business will be adversely impacted.Our growth and continued success will also depend on our ability to attract and retain additional highly qualified and skilled research and development,operational, managerial and finance personnel. However, we face significant competition for experienced personnel in the pharmaceutical field. Many of theother pharmaceutical companies that we compete against for qualified personnel have greater financial and other resources, different risk profiles and a longerhistory in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of thesecharacteristics may be more appealing to quality candidates than what we have to offer. If we cannot retain our existing skilled scientific and operationalpersonnel and attract and retain sufficiently skilled additional scientific and operational personnel, as required, for our research and development andmanufacturing operations on acceptable terms, we may not be able to continue to develop and commercialize our existing product candidates or newproducts. Further, any failure to effectively integrate new personnel could prevent us from successfully growing our company.Item 4.

Operating and Financial Review and Prospects – Liquidity and Capital Resources.”B.Business overview.OverviewWe are a clinical stage biopharmaceutical company focused on developing novel therapies designed to change the standard of care for urologicalpathologies. We have an innovative and broad pipeline of product candidates that we believe can overcome the deficiencies of current treatment options fora variety of urological conditions with a focus on uro-oncology. Our lead product candidates, MitoGel and VesiGel, are proprietary formulations of thechemotherapy drug Mitomycin C, or MMC, a generic drug, which is currently used off-label for urothelial cancer treatment only in a water-based formulationas an adjuvant, or supplemental post-surgery, therapy. We are developing our product candidates as chemoablation agents, which means they are designed toremove tumors by non-surgical means, to treat several forms of non-muscle invasive urothelial cancer, including low-grade upper tract urothelial carcinoma,or UTUC, and low-grade non-muscle invasive bladder cancer or NMIBC. We believe that MitoGel and VesiGel, which are both local drug therapies, have thepotential to significantly improve patients’ quality of life by replacing costly, sub-optimal and burdensome tumor resection and kidney removal surgeries asthe first-line standard of care. MitoGel and VesiGel may also reduce the need for bladder and upper urinary tract surgeries, including removal of the kidney,which are major surgical procedures typically performed when local endoscopic tumor resection fails to control the disease progression. Additionally, webelieve that our product candidates, which are based on novel formulations of previously approved drugs, may qualify for streamlined regulatory pathways tomarket approval.41 Our lead product candidates, MitoGel and VesiGel, are formulated using our proprietary reverse thermally triggered hydrogel, or RTGel, technology. Webelieve that RTGel-based drug formulations, which provide for the sustained release of an active drug, may improve the efficacy of treatment of various typesof urothelial cancer without compromising the safety of the patient or interfering with the natural flow of fluids from the urinary tract to the bladder. Ourformulations are designed to achieve this by increasing the dwell time as well as the tissue coverage of the active drug throughout the organ. Consequently,we believe that RTGel-based drug formulations may enable us to overcome the anatomical and physiological challenges that have historically contributed tothe lack of drug development for the treatment of urothelial cancer. No drugs have been approved by the U.S. Food and Drug Administration, or the FDA, forthe treatment NMIBC, in more than 15 years and for the treatment of UTUC, there are no drugs approved.We are currently evaluating the safety and efficacy of MitoGel, our novel sustained-release formulation of MMC, in patients with low-grade UTUC in a Phase3 pivotal, single-arm, open label clinical trial, which follows a recently completed “Compassionate Use” program for MitoGel for the treatment of the sameindication. The Compassionate Use Program was conducted in the U.S. and Israel. “Compassionate Use” is the use outside of a clinical trial of aninvestigational, or not approved, medical product when patient enrollment in a clinical trial is not possible, typically due to patient ineligibility or a lack ofongoing clinical trials. In the Compassionate Use Program, 22 patients were enrolled, 18 of which had confirmed low-grade UTUC. Of the 18 patients, 13patients had completed the six-weekly treatment regimen and were evaluated for tumor response. These 13 patients were evaluated for tumor response at theprimary evaluation time either endoscopically or through the use of a nonsurgical viewing instrument. Complete response was also confirmed by a cytology(urine) confirmation. Of these 13 patients, eight, or approximately 62% (or 8/18, or 44%, on an Intent to Treat basis), achieved a complete response, with amedian durability of response without recurrence of 12 months to date, based on investigator reports. Our analysis of the median recurrence-free durability ofthose patients who achieved a complete response is still ongoing, with, to our knowledge, only three of the eight patients recurring to date. To date, of thefive patients still ongoing without recurrence, to our knowledge, four have durability of response of 12 months or greater. Recurrences were generally ofsmall tumors, presenting with diameters of several millimeters in size that were consequently managed by endoscopic tumor resection. Importantly, of theeight patients that achieved a complete response, or a complete response following an initial partial response, four had a solitary kidney. As all the patients inthe Compassionate Use program were candidates for a nephroureterectomy, these four patients otherwise may have had their solitary kidney removed andbecome dialysis patients.Five out of the 13 evaluated patients achieved a partial response at the primary evaluation time. One patient who achieved a partial response received threeadditional monthly courses of MitoGel, and thereafter achieved a complete response. In this Compassionate Use program, MitoGel had been observed to bewell-tolerated. We have obtained Orphan Drug Designation for MitoGel for the treatment of UTUC as well as Fast Track Designation for the treatment ofpatients with low-grade UTUC not amenable to endoscopic resection or contraindicated for nephroureterectomy, which is the removal of the kidney andupper tract, including impaired renal function. We believe that MitoGel has the potential to become the first FDA-approved drug for the treatment of low-grade UTUC serving as a first-line chemoablation agent, sparing patients from repeated tumor resection surgeries and potentially reducing the need forbladder and upper urinary tract surgeries, including upper urinary tract removals.In addition, we completed evaluating the safety and efficacy of VesiGel, our novel sustained-release high dose formulation of MMC, for the treatment of low-grade NMIBC in a Phase 2a study that was conducted in Europe and Israel. Of the 22 patients treated in the VesiGel high dose group (80mg MMC), 19, orapproximately 86%, of the patients achieved a complete response at the primary evaluation time. Moreover, approximately 79% of the patients who achieveda complete response at the primary evaluation time with VesiGel in the study and who have been followed for 12 months thereafter, without receivingadditional treatments, remained recurrence free. This compares to approximately 40% to 60% of patients who historically achieve a 12-month durablecomplete response with TURBT as first-line treatment, followed by adjuvant treatments of MMC instillations into the bladder. We plan to file an IND forVesiGel in the first half of 2018; and, if accepted, we expect to commence a U.S.-based Phase 2b clinical trial for VesiGel shortly thereafter. We also intend topursue a 505(b)(2) regulatory pathway for VesiGel. We believe that VesiGel has the potential to replace tumor resection surgery and become the new first-linestandard of care for the treatment of low-grade NMIBC.We believe that urothelial cancer, which is comprised of bladder cancer and UTUC, affects a large and underserved patient population. Annual expendituresfor Medicare alone in the United States for the treatment of urothelial cancer were estimated to have been at least $4.0 billion in 2010 and are projected to beat least $5.0 billion in 2020. The majority of the expenditures is spent on tumor resection surgeries such as TURBT and upper urinary tract removals. In 2012,the estimated prevalence of urothelial cancer in the United States was 625,000 with an annual incidence of approximately 80,000. The 2012 prevalence ofeach of low-grade NMIBC and low-grade UTUC in the United States was approximately 325,000 and 14,500, respectively.Our clinical stage pipeline also includes Vesimune, our proprietary immunotherapy product candidate for the treatment of high-grade NMIBC, which mayinclude Carcinoma in Situ, or CIS. Vesimune is a novel, liquid formulation of Imiquimod, a generic toll-like receptor 7, or TLR7, agonist. Toll-like receptoragonists play a key role in initiating the innate immune response system. We believe that the combination of Vesimune with additional immunotherapydrugs, such as immune checkpoint inhibitors or sustain release42 chemotherapy drugs like VesiGel, could represent a valid alternative to the current standard of care for the post-TURBT adjuvant treatment of high-gradeNMIBC.BotuGel is our proprietary novel RTGel-based formulation of BOTOX, a branded drug, that we believe can potentially serve as an effective treatment optionfor patients suffering from overactive bladder. In October 2016, we announced the licensing of the worldwide rights to RTGel in combination withneurotoxins, including BOTOX, to Allergan Pharmaceuticals International Limited, or Allergan, a wholly owned subsidiary of Allergan plc, or the AllerganAgreement. In August 2017, we announced that Allergan had submitted an IND to the FDA in order to be able to commence clinical trials in the United Statesusing the RTGel in combination with BOTOX. In October 2017, Allergan commenced a Phase 2 clinical trial of BotuGel for the treatment of overactivebladder.Going forward, we will also refer to our product candidates, MitoGel, VesiGel and Vesimune, as UGN-101, UGN-102 and UGN-201, respectively.Our Product Candidate PipelineThe following chart summarizes the current status of our product candidate pipeline. Uro-Oncological Indications Targeted by Our Product CandidatesOur product candidates are administered locally using the standard practice of intravesical instillation directly into the bladder or upper urinary tract via acatheter. The instillation into the bladder is expected to take place in a physician’s office as a same-day treatment, in comparison with TURBT or similartumor surgical procedures, which are operations conducted under general anesthesia in a hospital setting and may require at least an overnight stay. Tumorsurgical procedures often have limited success due to the inability to properly identify, reach and resect all tumors. We believe that an effectivechemoablation agent can potentially provide better eradication of tumors irrespective of the detectability and location of the tumors. In addition, byremoving the need for surgery, patients may avoid potential complications associated with surgery and hospital-acquired infections.43 Bladder CancerThe bladder is a hollow organ in the pelvis with flexible muscular walls. Its main function is to store urine before it leaves the body. Urine is produced by thekidneys and is then carried to the bladder through the upper urinary tract tubes, called ureters. The bladder wall has four main layers. The innermost lining iscomprised of cells called urothelial or transitional cells, and this inner layer is called the urothelium or transitional epithelium. Beneath the urothelium, thereis a layer called the lamina propria. Next is a thick layer of muscle called the muscularis propria followed by a layer of perivesical fat. NMIBC tumor types are circled Bladder cancer accounts for approximately 90% to 95% of all new cases of urothelial cancer in the United States, with a prevalence of approximately580,000. Bladder cancer is nearly three to four times more common in men than women, and, with an average age at diagnosis of 73, mostly affects theelderly. Bladder cancers are described as non-muscle invasive or muscle-invasive based on how far into the wall of the bladder they have invaded. Themagnitude and rate of the spreading of the cancer is called “staging,” which ranges from Ta to T1 for NMIBC, and T2 to T4 for muscle-invasive bladdercancers, as defined by the American Joint Committee on Cancer TNM System. In addition, Carcinoma in Situ, or CIS, a form of NMIBC, has a stagingdesignation of Tis. Muscle-invasive bladder cancer, or MIBC, has an average five-year survival rate of 15% to 63%, depending on severity. MIBC representsa worse prognosis than NMIBC, which has a five-year survival rate of approximately 90%. NMIBC accounts for approximately 80% of all new cases ofbladder cancer diagnosed in the United States each year, which corresponds to an estimated annual incidence and prevalence of approximately 60,000 and465,000 cases, respectively.Non-muscle invasive bladder cancers are divided into two grades, low and high, with high-grade tumors more likely to recur and progress into muscle-invasive tumors. CIS tumors are all high-grade. Overall, approximately 70% of patients with NMIBC present with low-grade disease at diagnosis.The chart below indicates the prevalence of stage and grade of bladder cancer in the United States. 44 Upper Tract Urothelial CarcinomaUTUC refers to malignant changes of the transitional urothelial cells lining the upper urinary tract of the renal pelvis and ureter. UTUC typically exhibitshigh local recurrence and development of metastases. Similar to NMIBC, the prognosis of patients with UTUC correlates with the stage and grade of diseaseat the time of initial diagnosis. The key prognostic factor at the time of diagnosis of UTUC is whether the tumor is in the muscle-invasive or non-muscleinvasive stage. The number, size and location of tumors presented also represent important prognostic factors for UTUC. Approximately 40% of the patientsdiagnosed annually with UTUC in the United States present with non-muscle invasive UTUC. Non-muscle invasive UTUC is also divided into two grades,low and high. In two studies conducted in 1997 and 2003 of 30 and 20 patients with non-muscle invasive UTUC, 87% and 75% of patients were diagnosedwith low-grade non-muscle invasive UTUC, respectively.The chart below indicates the prevalence of stage and grade of UTUC in the United States. UTUC accounts for approximately 5% to 10% of all new cases of urothelial cancer, which corresponds to an estimated annual incidence in the United Statesof up to 7,500 cases. In 2012, the estimated prevalence of UTUC in the United States was approximately 45,000, of which approximately 14,500 had low-grade disease. UTUC is nearly three times more common in men than women and affects mostly the elderly.There are currently no drugs approved by the FDA for the treatment of UTUC, representing a significant unmet medical need. Moreover, the anatomicalcomplexity of the upper urinary tract, particularly the renal pelvis, presents significant challenges to the proper identification and ability to reach and resectall tumors in tumor resection surgical procedures. Consequently, patients with high-grade disease or patients with low-grade disease that present with a largenumber of tumors typically undergo nephroureterectomy, which is kidney and upper urinary tract removal. In addition, the stage and grade of UTUC are oftenmisdiagnosed, which we believe is due to the structural complexity of the upper urinary tract. Due to these factors, the current standard of care for thetreatment of UTUC is nephroureterectomy.Tumor resection, which aims to be a kidney sparing surgical procedure, is conducted only in patients with low-grade disease that present with a limitednumber of tumors. Such procedures are followed by adjuvant chemotherapy treatment, typically with MMC. However, the upper urinary tract’s anatomicalconstraints limit the effectiveness of surgical procedures and adjuvant chemotherapy treatments, leading to high rates of recurrence and risk for progression inthis patient population. In a study published in 2009 in the Journal of Endourology evaluating 57 patients with low-grade UTUC who underwent tumorresections, 89.5% of patients recurred with a mean of 5.5 recurrences per patient over a four-year period. Moreover, approximately 20% of the patients in thisstudy progressed and ultimately underwent kidney and upper urinary tract removal.We believe that because tumor resection procedures followed by adjuvant chemotherapy therapy are sub-optimal, nephroureterectomy is often used even inpatients that may be otherwise candidates for organ-sparing treatments.Non-Muscle Invasive Bladder CancerPatients treated with the current standard of care have up to an approximately 60% rate of recurrence of NMIBC within one year, and the rate of progressionof NMIBC to MIBC is between 20% and 30%. As a consequence, NMIBC patients often undergo multiple repeat TURBT procedures and adjuvantchemotherapy and immunotherapy treatments.45 The standard of care for treating NMIBC patients is TURBT followed by adjuvant chemotherapy or immunotherapy treatment. TURBT is a surgical operationfor tumor removal conducted under general anesthesia in a hospital setting and may require at least an overnight stay. Moreover, TURBT’s success is tied tothe physician’s ability to overcome challenges in properly identifying, reaching and resecting all tumors. No drugs have been approved by the FDA as first-line treatment for NMIBC and only three drugs have been approved by the FDA for NMIBC, all used as adjuvant treatment, following TURBT. Efficacy ofdrug treatments has historically been limited due to challenges presented by bladder physiology, specifically the fact that urine is produced and voidedfrequently, thus diluting the concentration of the drug almost immediately and causing the excretion of the drug from the bladder at first urine voiding.Our Competitive StrengthsWe believe our lead product candidates for uro-oncology, which are being developed by leveraging our expertise in drug development and our proprietaryformulation technology, have the ability to replace the costly, sub-optimal and burdensome tumor resection procedures that represent the current first-linestandard of care. Furthermore, we believe our proprietary formulation technology has broad applications and may allow us to develop additional productcandidates for indications within and beyond the urinary tract.Potential ability to develop non-surgical, first-line drug therapies for uro-oncology. Leveraging our innovative formulation technology, we are developingtwo lead product candidates, MitoGel and VesiGel, as potential replacements to first-line treatment for low-grade UTUC and NMIBC, respectively. BothMitoGel and VesiGel are chemoablation agents designed to overcome the challenges posed by the anatomy of the urinary tract by increasing the dwell timeand enhancing the tissue coverage of MMC. Clinical data generated to date supports our belief that our lead product candidates may be able to replace thecurrent first-line tumor surgical procedures, providing a chemoablation treatment that has the potential to better eradicate tumors irrespective of theirdetectability and location within the urinary tract. Of the 13 low-grade UTUC patients treated with MitoGel in a recently-completed Compassionate Useprogram and evaluated endoscopically or through the use of a nonsurgical viewing instrument for efficacy, eight achieved a complete response and theremaining five achieved a partial response at the primary evaluation time. In the case of VesiGel, 19 of 22, or approximately 86%, of the patients treated withthe high dose of VesiGel in a recently-completed Phase 2a trial conducted in Europe and Israel, evaluating the efficacy and safety of VesiGel’schemoablation properties, achieved a complete response at the primary evaluation time.Expertise in developing proprietary formulations of drugs for clinical benefit. We focus on developing proprietary RTGel formulations of previouslyapproved drugs whose efficacy for a particular indication is limited by current formulations or routes of administration. While we have not yet brought a drugto market, our expertise has enabled us to develop proprietary RTGel-based formulations for several previously approved drugs to date, including clinicalstage proprietary formulations of MMC and botulinum toxin. Our formulations are designed to significantly increase the dwell time and exposure of thedrugs to the target sites and limit the need for urine retention, potentially providing enhanced clinical activity, reduced patient burden and increased patientcompliance over existing formulations and modes of administration. With 13 Ph.Ds. and medical doctors on our staff, we have a strong research anddevelopment team to advance our product candidates.Lower development risks and costs for our pipeline product candidates. We expect the approval process for each of our current uro-oncology productcandidates to be conducted according to the FDA’s 505(b)(2) regulatory pathway, a streamlined, lower-cost and more well-defined pathway to drug approvalwhen compared to traditional drug development. Furthermore, two of our product candidates, MitoGel and Vesimune, have received Orphan DrugDesignation from the FDA for the treatment of UTUC and CIS, respectively, which we expect will provide seven years of marketing exclusivity followingFDA approval, if received. We submitted an IND for MitoGel in November 2016, which was accepted by the FDA in December 2016. We commenced a singlepivotal, open-label, single-arm Phase 3 clinical trial for the treatment of low-grade UTUC in the first quarter of 2017. The clinical trial is being conducted inthe United States and Israel with anticipated enrollment of approximately 74 patients. Additionally, we expect that our product candidates are more likely tobe safe and well-tolerated because they are novel formulations of previously approved drugs.Leverageable proprietary formulation technology. We believe that RTGel has multiple potential applications beyond urology. Our formulation know-howmay enable us to develop different drug formulations to facilitate the delivery, retention and sustained release of active drugs to a variety of targeted bodycavities. We believe that our proprietary formulation technology can improve the efficacy of locally administered drugs in body cavities such as the stomach,uterus and rectum that present anatomical and physiological challenges related to frequent wash out, rapid excretion and bodily secretions. In October 2016,we announced that we licensed worldwide rights to a proprietary RTGel formulation with BOTOX to Allergan for the treatment of overactive bladder andrelated indications pursuant to the Allergan Agreement.Strong intellectual property position. We have a robust intellectual property portfolio that includes 28 issued patents worldwide and more than 45 pendingpatent applications filed worldwide. In the United States, we have 13 granted patents that are directed to protect our lead product candidates MitoGel,VesiGel and Botugel as well as our RTGel technology and our other potential product candidates that are under preclinical review. These patents claimmethods, systems, and novel compositions for treating cancer in46 internal cavities, in particular treating a urinary tract cancer. These issued patents are expected to expire between 2024 and 2035. Additionally, the FDA hasgranted Orphan Drug Designation to MitoGel for the treatment of UTUC and Vesimune for the treatment of CIS bladder cancer, which potentially entitles usto marketing exclusivity for MitoGel and Vesimune for seven years following approval, if granted, by the FDA.Experienced and accomplished leadership team with proven track record. We have an experienced management team, with each member possessing morethan 15 years of biopharmaceutical and related industry experience. Our Chief Executive Officer, Ron Bentsur, successfully navigated Auryxia (ferric citrate)through the 505(b)(2) streamlined regulatory pathway to FDA approval. In addition, our Chairman, Arie Belldegrun, M.D., is a seasoned biotech executiveand was the founder, Chairman, Chief Executive Officer and President of Kite Pharma, which was recently sold to Gilead Sciences, Inc. for $11.8 billion. Dr.Belldegrun is also a urologist by training. We believe that our leadership team is well-positioned to lead us through clinical development, regulatoryapproval and commercialization for our product candidates.Our Growth StrategyWe intend to become the leading biopharmaceutical company focused on the development of novel therapies for local treatment of urological pathologies.The key elements of our strategy are as follows:Establish each of our lead product candidates, MitoGel and VesiGel, as the first-line treatment in its target indication. We believe that data from treatmentsin our Compassionate Use program conducted in the United States, Europe and Israel provide preliminary evidence of the potential safety and efficacy ofMitoGel for the treatment of low-grade UTUC. We submitted an IND for MitoGel with the FDA in November 2016, which was accepted by the FDA inDecember 2016, and we commenced a single pivotal Phase 3 clinical trial in the first quarter of 2017 pursuant to the FDA’s 505(b)(2) regulatory pathway. Werecently completed a Phase 2a randomized, open-label, single-arm, active-controlled clinical trial of VesiGel for the treatment of low-grade NMIBC,conducted in Europe and Israel. We expect to submit an IND for VesiGel in the first half of 2018, and, if accepted, to commence a Phase 2b U.S.-based clinicaltrial shortly thereafter. We also expect to pursue a 505(b)(2) regulatory pathway for VesiGel. We believe that these local drug treatments have the potential toreplace costly, sub-optimal and burdensome tumor resection and kidney removal surgeries to become the first-line standard of care.Expand our uro-oncology product pipeline. A Phase 1 clinical trial of Vesimune was completed under an IND in 12 patients with CIS, an aggressive form ofhigh-grade urinary bladder cancer. In the trial, 10 patients were evaluated for response, of which 40% achieved a complete response rate with Vesimune as asingle-agent treatment. We believe that combining Vesimune with immune checkpoint inhibitors or chemotherapy has the potential to serve as a treatmentoption for high-grade urothelial tumors. We are also pursuing preclinical oncology programs that take advantage of our RTGel technology. We areconducting preclinical programs for high-grade bladder cancer and high-grade UTUC. We may also evaluate in-licensing or acquiring additional productcandidates for the treatment of urological cancers.Utilize our proprietary technology to expand our pipeline to other body cavities and indications. We believe that RTGel may be suitable for multipleadditional applications. Our know-how may enable us to develop different drug formulations to facilitate the delivery, retention, increased dwell time andsustained release of active drugs to a variety of targeted body cavities. Beyond the urinary tract, we may target the gastrointestinal tract and the femalereproductive system. In the future, we may also choose to develop our RTGel technology in combination with other drugs to treat cancer and otherindications endemic to such body cavities.Evaluate and selectively pursue potential collaborations to develop improved formulations and product life-cycle management strategies. We entered intothe Allergan Agreement to research, develop, manufacture and commercialize pharmaceutical products that contain RTGel and clostridial toxins (includingBOTOX), alone or in combination with certain other active ingredients. This collaboration provides us with funding for our research and development effortsand may accelerate the development and commercialization of our approved products, if any. In addition, we may in-license or acquire additional productcandidates for urological indications. Such collaborations would allow us to obtain financial support and to capitalize on the expertise and resources of ourpotential partners, which could allow for new and improved versions of approved or clinical stage drugs and could accelerate the development andcommercialization of additional product candidates.47 RTGel: Our Reverse Thermally Triggered Hydrogel Platform TechnologyWe have developed RTGel, a novel proprietary polymeric biocompatible, reverse thermal gelation hydrogel, which, unlike the general characteristics of mostforms of matter, is liquid at lower temperatures and converts into gel form when heated. We believe that these characteristics promote ease of delivery intoand retention of drugs in body cavities, including the bladder and the upper urinary tract, by conforming to the anatomy of the target organ while preventingrapid excretion of the drug. The following images show the progression of five stages of RTGel at different temperatures. LT: Liquid at low temperatureBT: Converts into gel form at body temperatureRTGel’s components are polymer-based and are inactive ingredients that have been approved by the FDA for use in other products such as Oraqix, aperiodontal gel, Namenda, an oral solution for Alzheimer’s disease, and Xeloda, an oral chemotherapy. We formulate RTGel with an active drug: MMC in thecase of MitoGel and VesiGel, and botulinum toxin in the case of BotuGel. The resulting formulations are instilled intravesically in liquid form directly intothe bladder or upper urinary tract using standard instillation methodologies via catheters and thereafter convert into gel form at body temperature.Subsequently, upon contact with urine, RTGel gradually dissolves and releases the active drug over a period of several hours and is less affected by urinecreation and voiding cycles as compared to water formulations.We believe that RTGel, when formulated with an active drug, may allow for the improved efficacy of treatment of various types of urothelial cancer withoutcompromising the safety of the patient or interfering with the natural flow of fluids from the urinary tract to the bladder. RTGel achieves this by: •increasing the exposure of active drugs in the bladder and upper urinary tract by significantly extending the dwell time of the active drug whileconforming to the anatomy of the bladder and the upper urinary tract, which allows for enhanced drug tissue coverage. For example, the averagedwell time of the standard MMC water formulation, currently used as adjuvant treatment, in the upper urinary tract is approximately five minutes,compared to approximately six hours when MMC is formulated with RTGel; •administering higher doses of an active drug than would otherwise be possible using standard water-based formulations. For instance, it is onlypossible to dissolve 0.5 mg of MMC in 1 ml of water while it is possible to formulate up to 8 mg of MMC with 1 ml of RTGel; and •maintaining the active drug’s molecular structure and mode of action.These characteristics of RTGel enable sustained release of MMC in the urinary tract for both MitoGel and VesiGel, and of botulinum toxin in the case ofBotuGel. Further, RTGel may be particularly effective in the bladder and upper urinary tract where tumor visibility and access are challenging, and wherethere exists a significant amount of urine flow and voiding. We believe that these characteristics of RTGel may prove useful for the local delivery of activedrugs to other bodily cavities in addition to the bladder and upper urinary tract.MMC—Our Target Active Drug for the Treatment of UTUC and NMIBCMMC is a generic drug currently utilized off-label as the standard adjuvant chemotherapy for the treatment of low-grade UTUC and NMIBC after tumorresection, such as TURBT. MMC, a chemotherapy agent, is typically administered using a water-based formulation, which has a relatively short dwell time inthe bladder limited to first voiding. MMC often causes temporary irritation of the bladder, including the need to urinate frequently and urgently. This oftenresults in first voiding occurring shortly after instillation. In the upper urinary tract, the dwell time is limited to approximately five minutes as urine flowscontinuously and no active retention by the patient is feasible. Numerous in vitro models, in vivo studies and computer simulations have shown thatincreased dwell time of MMC in the bladder results in more efficacious treatment of bladder cancer. In one such study, it was shown that MMC activityincreased with exposure time. Specifically, the MIC90, or mean inhibitory concentration that causes 90% inhibition in cell growth, was 11-fold lower whenexposure time was increased from 30 minutes to eight hours.48 MMC’s main effect is on the cancer cell’s DNA and has been demonstrated to be most effective when the cancer cell is in its S-phase, or synthesis phase,during which the DNA is replicated. Each cancer cell goes through various phases during the cell cycle. However, the cell cycle is not synchronized in allcancer cells, which means that at any given point in time only a portion of the cancer cells are at their S-phase, or susceptible to the instilled MMC in thebladder. Thus, because our RTGel-based MMC sustained-release formulations, MitoGel and VesiGel, provide for a significantly longer dwell time of MMCin the upper urinary tract and in the bladder as compared to standard MMC water formulations, there is a greater chance that tumor cells will go through theirS-phase while the instilled MMC is still present using MitoGel or VesiGel, potentially resulting in a higher percentage of tumor cells being affected by theinstilled MMC.MitoGel: Our Product Candidate for the Treatment of Low-Grade Upper Tract Urothelial CarcinomaWe are developing MitoGel, our novel sustained-release formulation of MMC, for the treatment of low-grade UTUC. We have observed preliminary evidenceof the efficacy of MitoGel in an investigator-initiated Compassionate Use program for the treatment of unresectable UTUC. Additionally, the FDA grantedMitoGel Orphan Drug Designation for the treatment of UTUC and Fast Track Designation. We plan to develop MitoGel through the FDA’s 505(b)(2)regulatory pathway. We commenced a pivotal, open-label, single-arm Phase 3 clinical trial for MitoGel in the first quarter of 2017.Limitations of Current Therapies for Upper Tract Urothelial CarcinomaThere are currently no drugs approved by the FDA for the treatment of UTUC, representing a significant unmet medical need. The current standard-of-care forthe treatment of UTUC is nephroureterectomy, which is complete kidney and ureter removal. Recent advances in resection instrument technology haveallowed physicians in some cases to treat patients with low-grade UTUC using endoscopic tumor resection, a kidney-sparing treatment, rather thannephroureterectomy followed by adjuvant chemotherapy, typically MMC, treatment. However, the specific anatomy and physiology of the upper urinarytract make the performance of organ-sparing endoscopic tumor resection and instillation of adjuvant chemotherapy challenging, leading to high recurrencerates. Patients often undergo multiple endoscopic resection procedures, which increases the probability of potential complications of resection, includingperforation and ureteral stricture, or a narrowing of the ureter. A recent study published in 2009 in the Journal of Endourology, evaluating 57 patients withlow-grade UTUC who underwent tumor resections showed that recurrence occurred in 89.5% of patients, with a mean of 5.5 recurrences per patient, over afour-year period. Moreover, approximately 20% of the patients in this study progressed and ultimately underwent kidney and upper tract removal.MMC is currently administered using a water-based formulation, which limits the dwell time in the bladder until first voiding. In the upper urinary tract, thedwell time of MMC is approximately five minutes as urine flows continuously and no active retention by the patient is feasible.Our Solution: MitoGelMitoGel is our novel sustained-release RTGel-based formulation of MMC that we are developing for the treatment of low-grade UTUC. RTGel is liquid atlower temperatures and converts into gel form at body temperature. This temperature-dependent viscosity characteristic allows for simple and convenientinstillation of the cooled MitoGel in its liquid form to the upper urinary tract via standard catheters. Once instilled, MitoGel converts into gel form in lessthan 10 minutes at body temperature. Subsequently, upon contact with urine, MitoGel gradually dissolves and releases the active drug, MMC, over a periodof several hours versus several minutes for MMC in its water-based formulation. We believe that this substantial increase in dwell time of MMC positionsMitoGel as a potential first-line chemoablation treatment for low-grade UTUC, potentially sparing patients from repeated tumor resection surgeries andpotentially reducing the need for bladder and upper urinary tract surgeries, including upper urinary tract removal.The Orphan Drug Designation granted to MitoGel for the treatment of UTUC potentially entitles us to marketing exclusivity for MitoGel for seven yearsfollowing approval by the FDA, if granted, as well as priority review of our New Drug Application, or NDA. We believe Fast Track Designation may allow usto obtain priority or expedited review of our NDA filing as well as the possibility for a rolling NDA submission.Initial Clinical Results for MitoGelMitoGel was evaluated in an investigator-initiated Compassionate Use program for the treatment of severe, non-resectable UTUC, which commenced inSeptember 2014. The Compassionate Use program, which was conducted in the United States, Europe and Israel, included patients diagnosed with unilateraland bilateral low- and high-grade UTUC, as well as patients with a solitary kidney. Patients in the Compassionate Use program received six weeklyinstillations of MitoGel administered directly to the upper urinary tract. Consistent with the nature of Compassionate Use programs, which are investigator-initiated programs, a statistical plan or49 primary endpoint was not used as in a regular clinical trial. Approximately four weeks following the completion of the treatment course, the patients wereevaluated for response. Patients were visually evaluated endoscopically or through the use of a nonsurgical viewing instrument, with additional confirmationthrough urine cytology, or examination of cells collected from a urine specimen. At the evaluation time, which was approximately four weeks following thecompletion of the treatment course, patients were deemed to have achieved a complete response if, in the judgment of the physician, no tumors initiallydiagnosed by the physician were detected and a partial response if, in the judgment of the physician, the size or number of tumors had decreased or if,following an initial complete response, there is tumor recurrence within three months after the evaluation time. Safety and feasibility of treatment withMitoGel were also evaluated. Twenty-two patients were treated in the study, with more than 130 instillations of MitoGel performed. Of the 22 patientstreated, 18 were assessed as having low-grade UTUC. Of the 18 patients assessed as having low-grade disease, 14 completed six instillations of MitoGel. Ofthese 14 patients, 13 were evaluated for response and one could not be evaluated to confirm response. Of the 13 patients who were evaluated for response,eight, or approximately 62%, achieved a complete response and five, or approximately 38%, achieved a partial response at the primary evaluation time. Oneof the patients who received a partial response subsequently received an additional three courses of MitoGel and thereafter achieved a complete response.Of the eight patients who have achieved a complete response at the primary evaluation time, we are aware of three patients who have subsequentlyexperienced recurrences to date. Recurrences were generally of small tumors, a few millimeters in diameter, and were manageable by endoscopic tumorresection. To our knowledge, five of the eight patients have not recurred to date, with three of the five patients having achieved durability of 12 months orgreater to date. The median durability for these eight patients is still ongoing and is now greater than nine months, based on investigator reports. The follow-up evaluation plan for patients in our Compassionate Use program is determined by each individual investigator and varies from patient to patient, and somepatients have not undergone follow-up evaluation or have been lost to follow-up. As part of the ongoing single pivotal Phase 3 clinical trial, in order topotentially further extend durability, patients who achieve a complete response at the primary disease evaluation visit will be followed for durability ofresponse and will receive monthly MitoGel maintenance instillations for up to 12 months.MitoGel was observed to be well-tolerated in the Compassionate Use Program. The main observed adverse events, or AEs, related to MitoGel have beenfatigue, allergic reaction, nausea, fever, and dysuria, which is pain or difficulty while urinating. All of the AEs that have been observed to date are known sideeffects associated with the use of MMC and appear on the MMC label as potential side effects. Various serious adverse events, or SAEs, were also reportedmost of which were determined to be unrelated to treatment with MitoGel. These SAEs include acute pyelonephritis, a kidney infection caused by bacteria;hydronephrosis, which is the swelling of the upper urinary tract due to a build-up of urine caused by some degree of obstruction; severe arrhythmia, which isa severe abnormal heart rhythm; cardiac asthma, which is a medical diagnosis of wheezing, coughing or shortness of breath due to congestive heart failure;aggravation of renal function; hyperkalemia, which is a condition of elevated levels of potassium in the blood; pancytopenia, which is a deficiency of redcells, white cells and platelets in the blood; scarring and narrowing of the calyceal infundibulum, which was most probably present at baseline; asymptomaticextravasation from the upper tract, which is leakage of fluids from the upper tract to the surrounding tissue; and death.This Compassionate Use program was allowed by the FDA to accumulate safety and efficacy data. In the first quarter of 2017, we commenced a pivotal, open-label, single-arm Phase 3 clinical trial of MitoGel for the treatment of low-grade UTUC.The following images show pre-treatment and post-MitoGel treatment results from one low-grade UTUC patient in the Compassionate Use program.

The bottom right image is a post-treatment x-ray of the ureter whichreveals no obstruction within the ureter.IND-Enabling Studies for MitoGelAs part of our IND-enabling work for MitoGel, we have completed a large-scale good laboratory practices, or GLP, toxicity study in an upper urinary tractswine model in which more than 250 instillations of MitoGel were performed. This study evaluated the safety of the procedure and MitoGel administration,also utilizing higher dosage levels than those used in the clinical settings. In this GLP toxicology study, the instillation of MitoGel was found to be safe. Weare also currently conducting chemistry, manufacturing and controls, or CMC, studies as part of our IND-enabling efforts.Next Steps in the Clinical Development of MitoGelBased on discussions with the FDA, we intend to develop MitoGel through the FDA’s 505(b)(2) regulatory pathway. We submitted an IND for MitoGel inNovember 2016, which was accepted by the FDA in December 2016. We commenced a pivotal, open-label, single-arm Phase 3 clinical trial of MitoGel forthe treatment of low-grade UTUC in the first quarter of 2017. (*) Only if clinical trial is successfully completedThis Phase 3 clinical trial is being conducted in the United States and Europe with anticipated enrollment of approximately 74 patients. We expect thisclinical trial, if successfully completed, to support an NDA for low-grade UTUC for MitoGel. The patients will initially receive six weekly instillations ofMitoGel. The primary efficacy endpoint is expected to be the complete response rate, defined as the percentage of patients with a complete response at theprimary disease evaluation visit, which occurs approximately four weeks following the sixth weekly instillation. In addition, patients who achieve acomplete response at the primary disease evaluation visit will be followed for durability of response. Such patients will also receive monthly MitoGelmaintenance instillations for up to 12 months. If this clinical trial is successfully completed, we currently anticipate submitting an NDA for MitoGel in thefirst quarter of 2019. In the Phase 3 trial, to date, MitoGel therapy has been well tolerated. Adverse events encountered in treated subjects include theexpected effects of Mitomycin C administration to the urinary tract (pain and urinary tract irritation). In addition, transient perturbation of laboratorymeasures of renal and hematopoietic function has been observed. No study participants have required medical intervention to address these changes.VesiGel: Our Product Candidate for the Treatment of Low-Grade Non-Muscle Invasive Bladder CancerVesiGel is our novel sustained-release formulation of high dose MMC that we are developing for the treatment of low-grade NMIBC as a first-line non-surgical chemoablation alternative to TURBT. We recently completed a Phase 2a randomized, open-label, single-arm active-controlled clinical trial inEurope and Israel that evaluated the safety and efficacy of VesiGel (40mg and 80mg MMC) in low-grade NMIBC. We commenced the trial in September2013 and the last patient was enrolled in March 2016. 19 of 22, or approximately 86%, of the patients with confirmed low-grade NMIBC treated in this trialachieved complete responses in the 80mg MMC dose group of VesiGel at the primary evaluation time, and therefore did not require surgical intervention.Approximately 79% of the patients who achieved a complete response at the primary evaluation time with VesiGel treatment and who had been followed for12 months thereafter remained recurrence free and were able to sustain this durable complete response without receiving any additional treatment during thisperiod. This compares to approximately 40% to 60% of patients who historically have been able to sustain a 12-month durable complete response followingTURBT as first-line treatment followed by additional adjuvant treatments of MMC instillations into the bladder.We expect to submit an IND for VesiGel in the first half of 2018, and, if accepted, to commence a Phase 2b U.S. based clinical trial shortly thereafter.51 Limitations of Current Therapies for Non-Muscle Invasive Bladder CancerTumor grade and stage are the most important variables for determining the likelihood of progression from NMIBC to MIBC. The three stages of NMIBC are:Ta (70%), T1 (20%) and CIS or Tis (10%). Approximately 70% of NMIBC patients have a tumor that is classified as low-grade upon diagnosis. Ta and CIS arelimited to the urothelial layer, and T1 is limited to the layer below, which is the lamina propria.Recurrence, which occurs in approximately 80% of patients, is the primary threat for NMIBC patients. Multiplicity, or number of tumors, tumor size and priorrecurrence rate are the most important variables in determining the likelihood and potential severity of recurrence. In T1 and CIS NMIBC patients,progression, which occurs in approximately 45% of patients, is the main threat. Treatment ranges from one or more TURBT procedures followed by adjuvantchemotherapy or immunotherapy instillation(s) in NMIBC patients with a low risk of recurrence to cystectomy for the treatment of NMIBC patients with ahigh risk of recurrence.TURBT is conducted in a hospital setting under general anesthesia and can often have side effects and complications. The most common complications, risksand limitations of TURBT include: •bleeding at the time of surgery that requires clot irrigation and mild burning; •infection of the bladder; •injured urethra and bladder perforation with potential intra-abdominal leakage; •reimplantation and cell migration; •repeat TURBT procedures, which are necessary for approximately 10% of patients within three months; •complete removal of tumor tissue often not being feasible; •potential recurrence of up to 25% of the tumors at the original treatment site; and •some tumors not being detectable.Post-operative adjuvant treatments for NMIBC, which are given to prevent reimplantation of the cancerous cells, consist primarily of chemotherapy in thecase of low-grade tumors and immunotherapy in the case of high-grade tumors, and are administered intravesically via catheter. Adjuvant intravesicalchemotherapy is used primarily in low-grade tumors following TURBT in order to try to delay tumor recurrence but is not used as a chemoablation agent. Therationale is to expose tumors to high local drug concentrations while minimizing the systemic exposure, thereby enhancing the treatment effect and reducingthe drug toxicity. However, these traditional adjuvant treatments to treating bladder cancer have been limited because, after instillation, the drugconcentration is reduced, and the drug is washed out due to urine voiding. As a result, the cancerous tissue is not exposed to the chemotherapy drug for theoptimal length of time.No drugs have been approved by the FDA as first-line treatment for NMIBC and only three drugs have been approved for NMIBC, all used as adjuvanttreatment: Thiotepa, which was approved in 1959; bacille Calmette-Guerin, or BCG, which was approved in 1989; and Valstar, which was approved in 1998.MMC is the drug used most often for intravesical chemotherapy. It is used off-label as an adjuvant treatment in the post-operative setting for low-gradetumors with high risk of recurrence. Other drugs that can be used include docetaxel and gemcitabine. BCG, an immunotherapy-based drug, is used as anadjuvant treatment for patients with high-grade NMIBC. Upon recurrence, which occurs in approximately 35% of patients, the patients undergo anotherround of BCG therapy with a response rate of 30% to 50%. Radical cystectomy, or surgical removal of the bladder, is also a common treatment option forpatients who fail multiple intravesical BCG therapies. However, treatment with BCG is associated with severe side effects, as evidenced by a Black Boxwarning on the label, which is a warning placed on a prescription drug’s label by the FDA and is designed to call attention to serious or life-threatening risks.We are not aware of any drugs currently in development for the treatment of NMIBC that take into consideration bladder physiology, specifically the factthat urine is produced and voided frequently, thus diluting the concentration of the active drug almost immediately.Our Solution: VesiGelVesiGel, an RTGel-based formulation of high dose MMC, is our product candidate for the treatment of low-grade NMIBC. VesiGel is administered locallyusing standard catheters and is designed to conform to the bladder’s anatomy and persist in the bladder despite urine flow and bladder movement. Onceinstilled, VesiGel converts into gel form within approximately 10 minutes at body temperature. Subsequently, upon contact with urine, VesiGel graduallydissolves and releases the active drug, MMC, over a period of52 several hours versus the time until first voiding, often less than an hour, for MMC in its current water-based formulation, without compromising the safety ofthe patient or interfering with the natural flow of urine out of the bladder. We believe that the resulting significantly increased dwell time of MMC in thebladder prolongs exposure of MMC to the tissue and therefore has the potential to chemoablate visible and unseen tumors. As a result of these properties, ourgoal is to develop VesiGel as a first-line chemoablation non-surgical alternative to TURBT for the treatment of low-grade NMIBC.Phase 2a Clinical TrialWe completed a Phase 2a randomized, open-label, single-arm, active-controlled clinical trial in Europe and Israel that evaluated the safety and efficacy ofVesiGel 0.06% (40 mg MMC in 64 ml gel) and VesiGel 0.12% (80 mg MMC in 64 ml gel) in low-grade NMIBC compared to the intravesical instillation of40 mg of MMC in water (MMC 0.1%). We commenced the trial in September 2013 and the last patient was enrolled in March 2016. In this trial, patientsunderwent six weekly instillations according to their assigned treatment arm. The primary endpoint of the trial used for observational purposes only is thecomplete response rate at the primary disease endpoint, which is evaluated approximately four weeks after the sixth weekly installation. Safety, feasibility oflocal treatment with VesiGel and durability of response are also being evaluated. 81 patients were enrolled, 65 of whom have been evaluated for response. Ofthe 65 evaluable patients in the study, 20, 22 and 23 patients were in the VesiGel 40mg MMC, VesiGel 80mg MCC and the water-based 40mg MMC controlarm, respectively. The results to date indicate complete response rates at the primary evaluation time of 45%, 86% and 70% for VesiGel 40mg MMC, VesiGel80mg MMC and water-based 40mg MMC control arm, respectively.In treating low-grade NMIBC, resection of small tumors is primarily conducted in the outpatient setting, typically without anesthesia using fulguration, aprocedure that destroys the diseased area in the lining of the bladder by burning using electric current. The effectiveness of tumor resection in these cases ishigh and the one-year recurrence rate is estimated to be only 10%. However, in patients with larger tumors and multiple tumors, standard managementincludes surgical removal using TURBT, a procedure conducted in the operating room in a hospital setting under general anesthesia, which may require atleast an overnight stay. TURBT is associated with increased risks and costs and higher recurrence rates that can reach up to 60%.When evaluating the effect of chemoablation on large tumors that would typically be treated with TURBT, we observed a more profound difference in thecomplete response rate between the VesiGel 80mg MMC arm compared to the water-based 40mg MMC control arm. In tumors less than or equal to 1 cm2 insize, the complete response rate at the primary evaluation time was 78% (18 patients) and 88% (16 patients) in the water-based 40mg MMC control groupand the VesiGel 80mg MMC group, respectively. However, in tumors greater than 1 cm2 in size, the complete response rate at the primary evaluation timewas 40% (five patients) and 83% (six patients) in the control group and VesiGel 80mg MMC group, respectively.The graph below illustrates the complete response rates by tumor size for the VesiGel 80mg MMC and water-based 40mg MMC control treatment arms. We also observed a difference in the complete response rate between the VesiGel 80mg MMC arm compared to the water-based 40mg MMC control armwhen evaluating the effect of chemoablation on the number of tumors. In cases of three or fewer tumors, the53 complete response rate at the primary evaluation time was 80% (15 patients) and 81% (16 patients) in the water-based 40mg MMC control group and theVesiGel 80mg MMC group, respectively. However, in cases of more than three tumors, cases that would typically be treated using TURBT, the completeresponse rate at the primary evaluation time was 50% (eight patients) and 100% (six patients) in the water-based 40mg MMC control group and the VesiGel80mg MMC group, respectively.The graph below illustrates the complete response rates by tumor volume for the VesiGel 80mg MMC and water-based 40mg MMC control treatment arms. To date, the incidence of AEs reported for both VesiGel groups in the study has been low and appears similar to that of the active control group, with themajority of the AEs having occurred in the VesiGel 80mg MMC group. The main observed AEs related to VesiGel have been dysuria, allergy, lower urinarytract symptoms, and hematuria, or the presence of blood in the urine. The AEs that have occurred were associated with the use of MMC, MMC intravesicalinstillation or the cystoscopy procedure itself. The MMC-related AEs were primarily burning sensation, rash, urgency, and dysuria, which is painful ordifficult urination. These AEs appear on the MMC label as potential side effects. SAEs were also reported, including allergy, weakness, hematuria, difficult orlabored breathing, lower urinary tract symptoms other than dysuria, and death. None were determined to be related to VesiGel, except for two allergy casesthat were resolved.The following images show cytoscopic views of complete responses in a low-grade NMIBC patient treated with VesiGel. 54 The image to the left is a pre-treatment cystoscopic view of a tumor located in the bladder. The image to the right is a post-treatment cystoscopic view of thesame location following VesiGel chemoablation treatment.Dose Escalation Study for VesiGelIn parallel to our Phase 2a clinical trial, in the first half of 2015, we initiated a dose escalation study for patients with NMIBC in Europe and Israel to evaluatethe safety and efficacy of VesiGel at dose levels higher than 80 mg MMC. To date, we have enrolled 14 patients. All patients to date have been treated withthe 120 mg MMC in 60 ml gel dose, or 0.2% concentration. Of the 12 low-grade NMIBC patients evaluated to date, 10 have achieved a complete response(83%). However, at the 120 mg MMC dose level, we also observed a higher rate of MMC-related AEs than in patients treated with the 80 mg MMC dose. Fiveof 12 patients did not complete six weekly instillations due to their non-compliance, although three of these five patients achieved a complete response. As aresult, we have determined to focus our development efforts going forward on the 80 mg MMC dose level.Phase 1 Clinical Trial for VesiGelIn early 2014, we completed a Phase 1 clinical trial in India evaluating two earlier formulations of VesiGel. Patients underwent six weekly instillationsaccording to their assigned treatment of RTGel (40 ml) formulated with either 40 mg MMC or 80 mg MMC. Following completion of the six instillations,patients were evaluated for safety and efficacy. We enrolled 19 patients, 15 of whom were evaluated for response to treatment. Of the 15 evaluable patients,seven achieved a complete response, with two out of five from the 40 mg MMC arm and five out of 10 from the 80 mg MMC arm. Patients were followed forone year after treatment. The results of this study led to the initiation of our Phase 2a clinical trial, in which we are using a higher volume of RTGel, 64 mlcompared to 40 ml, in an attempt to further enhance the efficacy of the 40 mg and 80 mg MMC VesiGel dose groups, by increasing the dwell time of the drug.Durability of ResponsePer protocol, the patients in our Phase 2a and Phase 1 clinical trials were followed for 12 months after the primary disease evaluation time point. To date, 41patients treated with different VesiGel formulations completed the 12-month follow-up period, 28 of whom achieved a complete response at the primarydisease evaluation time point and did not receive any additional treatments. Of these 28 patients, 28 (100%), 25 (89%), 24 (86%) and 22 (79%) had durablecomplete responses at three, six, nine and 12 months, respectively.The graph below demonstrates the durability data for the patients treated with VesiGel who achieved a complete response at the primary disease evaluationtime point and were followed for 12 months. We believe that these results support our belief that VesiGel, acting as a chemoablation agent, can replace TURBT, with the possibility of improvingdurability of response.Next Steps in the Clinical Development of VesiGelWe completed the Phase 2a clinical trial in the first half of 2017. We recently met with the FDA to discuss next steps in the clinical development program forVesiGel. We plan to submit an IND for VesiGel in the first half of 2018 and, if accepted, to commence a U.S. based Phase 2b clinical trial for VesiGel shortlythereafter.55 Vesimune: Our Product Candidate for the Treatment of High-Grade NMIBCWe are developing Vesimune, our immune-modulation product candidate, for the treatment of high-grade NMIBC. A Phase 1 dose escalation study wasconducted in 23 NMIBC patients and Vesimune appeared to be well-tolerated in the study. This was followed by a Phase 1 pilot study under an IND in 12patients with CIS bladder cancer in the United States. 40% of the 10 evaluable patients achieved a complete response, and Vesimune was observed to be well-tolerated in the trial. We intend to further investigate the use of Vesimune for the treatment of high-grade NMIBC, as a single agent or possibly combining itwith VesiGel, MitoGel or with immune checkpoint inhibitors.Limitations of Current Therapies for High-Grade NMIBCHigh-grade NMIBC is a highly aggressive form of bladder cancer. TURBT is the initial treatment of choice for high-grade NMIBC; however, the high rates ofrecurrence and significant risk of progression to muscle-invasive tumors are particularly dangerous. Bladder removal can be the first treatment of choice foryoung, otherwise healthy patients with high-grade disease or for patients who cannot tolerate BCG. BCG, an immunotherapy-based drug, is the currentstandard of care as an adjuvant therapy post-resection in high-grade tumors. However, treatment with BCG is associated with severe side effects, as evidencedby a Black Box warning on the label.Our Solution: VesimuneWe believe that Vesimune, our immune-modulation product candidate, could represent a valid alternative to the current standard of care for the BCGadjuvant, post-TURBT treatment of high-grade NMIBC. Vesimune’s active ingredient is Imiquimod, an imidazoquinoline, synthetic immune modulator,which specifically targets TLR7, which is expressed in bladder cancer cells. Toll-like receptors are pattern recognition receptors whose importance instimulating innate and adaptive immunity has been established by recent studies. Toll-like receptors are able to sense microbial components as well as host-derived endogenous molecules released by injured tissues and play a critical role in defending against invading pathogens.Imiquimod, in its topical formulation, is FDA approved for several indications, including superficial basal cell carcinoma. Vesimune is a liquid formulationof Imiquimod for intravesical administration that has been optimized for delivery in the urinary tract. Vesimune does not use our RTGel technology. Webelieve that Vesimune may elicit an adaptive immune response in the presence of released bladder cancer antigens, which may translate into a long lastingacquired immune response. We also believe the combination of Vesimune with immune checkpoint inhibitors could further increase the adaptive immuneresponse and potentially represent a viable alternative to BCG for the adjuvant treatment of high-grade NMIBC or UTUC.We have obtained Orphan Drug Designation for Vesimune for the treatment of CIS in the bladder. We have an active IND for Vesimune, which has beeneffective since 2013.We acquired Vesimune from Telormedix SA, a private Swiss-based biotechnology company, in the fourth quarter of 2015. Telormedix conducted all of theprevious studies related to Vesimune, including the Phase 1 and Phase 1b studies.Vesimune Clinical Results and Post-Study Follow-UpVesimune was evaluated in a Phase 1 dose escalation study that enrolled 23 patients diagnosed with NMIBC. Vesimune was well-tolerated at the doses used.Subsequently, a Phase 1b study of Vesimune was conducted under an IND in patients with CIS bladder cancer in the United States. The Phase 1b study wascommenced in April 2013 and completed in February 2014. Patients were dosed with Vesimune 0.4% weekly for six weeks. The study was designed toevaluate the safety and preliminary efficacy of Vesimune in CIS patients. The primary efficacy endpoint for observational purposes only was the rate ofcomplete response at five to seven weeks after the sixth weekly instillation. Twelve patients were enrolled into the pilot study, of which 10 patients wereevaluable for response. Four of the 10 patients, or 40%, achieved a complete response. Vesimune was observed to be well tolerated in this trial. The mostcommon AEs related to Vesimune were urination urgency, dysuria, fatigue, urinary tract infections and hematuria. One SAE, a urinary tract infection, wasobserved and was resolved. For observational purposes, patients were followed for an additional six-month period beyond the completion of the study,referred to as the Post-Study Follow Up. Of the four patients who had achieved a complete response with Vesimune in the study, two patients remaineddisease free at the end of the Post-Study Follow Up while receiving no additional therapy. The two other patients who had achieved a complete response withVesimune in the study also remained disease free at the end of the Post-Study Follow Up while receiving BCG therapy during this period.56 The chart below represents the complete response rates for patients receiving only Vesimune: Next Steps in the Clinical Development of VesimuneWe intend to further investigate the use of Vesimune for the treatment of high-grade NMIBC, as a single agent or possibly combined with MitoGel, VesiGelor other immunotherapy agents. Such a combination study would evaluate whether this multimodality approach, harnessing the power of the immune systemtogether with the chemoablation properties of VesiGel or MitoGel, can provide a safe and effective approach for the treatment of high-grade urothelialtumors.Preclinical ProgramsUsing our proprietary RTGel formulation technology, we are pursuing additional preclinical programs to expand and enhance our uro-oncology productportfolio. In particular, we are pursuing preclinical programs for high-grade bladder cancer and high-grade UTUC using checkpoint inhibitors such as an antiPD-L1 or an anti CTLA-4.License Agreement with AllerganIn October 2016, we entered into the Allergan Agreement with Allergan and granted Allergan an exclusive worldwide license to research, develop,manufacture and commercialize pharmaceutical products that contain RTGel and clostridial toxins (including BOTOX), alone or in combination with certainother active ingredients, to which we refer as the Licensed Products, which are approved for the treatment of adults with overactive bladder who cannot use ordo not adequately respond to anticholinergics. Additionally, we granted Allergan a non-exclusive, worldwide license to use certain of our trademarks asrequired for Allergan to practice its exclusive license with respect to the Licensed Products.Under the Allergan Agreement, Allergan is solely responsible, at its expense, for developing the Licensed Products and obtaining all regulatory approvals forLicensed Products worldwide. Allergan is also solely responsible, at its expense, for commercializing the Licensed Products worldwide after receiving theregulatory approval to do so. Allergan is required to use commercially reasonable efforts to develop and commercialize the Licensed Products for overactivebladder in certain major market countries.We will supply Allergan with certain quantities of RTGel for development of Licensed Products through Phase 2 clinical trials using BOTOX together withRTGel in patients with overactive bladder, at Allergan’s request and expense. Allergan has the right to reduce the next milestone payment to us if there is amaterial supply failure from us. Prior to completion of the first Phase 2 clinical trial, Allergan has the right to request that we transfer to Allergan ourmanufacturing process for RTGel and Allergan will assume the responsibility to manufacture RTGel and Licensed Product for its own development andcommercialization activities.Allergan paid us a nonrefundable upfront license fee of $17.5 million upon signing the agreement, and, in the third quarter of 2017, we received anadditional $7.5 million milestone payment upon the submission by Allergan of an IND to the FDA for a Licensed Product. In October 2017, we announcedthat Allergan had begun a Phase 2 study of RTGel in combination with BOTOX for the treatment of overactive bladder.Further, we are eligible to receive additional material milestone payments of up to an aggregate of $200.0 million upon the successful completion of certaindevelopment, regulatory and commercial milestones, including $20.0 million upon initiation of a Phase 3 clinical trial for a Licensed Product for overactivebladder; $15.0 million upon initiation of a Phase 3 clinical trial for a Licensed Product for a specified second indication; $50.0 million and $25.0 millionupon the first commercial sale of a Licensed Product for57 overactive bladder in the United States and the European Union, respectively; $25.0 million and $15.0 million upon the first commercial sale of a LicensedProduct for a specified second indication in the United States and the European Union, respectively; and $50.0 million upon net sales of all LicensedProducts of $500.0 million. Allergan will pay us a tiered royalty in the low single digits based on worldwide annual net sales of Licensed Products, subject tocertain reductions for the market entry of competing products and/or loss of our patent coverage of Licensed Products. We are responsible for payments toany third party for certain RTGel-related third party intellectual properties.Under the Allergan Agreement, Allergan granted us a non-exclusive, sublicensable, fully paid-up, perpetual, worldwide license under any improvementsAllergan makes to the composition, formulation, or manufacture of RTGel for the research, development, manufacture and commercialization of any productcontaining RTGel and any active ingredient (other than a clostridial toxin) for all indications other than indications covered by the agreement and anexclusive, sublicensable, royalty-bearing (in low single digits), perpetual worldwide license under such improvements for use in the prevention or treatmentof oncology indications.We plan to continue to research, develop and commercialize other products combining RTGel with other active ingredients, except that there are certainrestrictions with respect to the overactive bladder and neurogenic detrusor overactivity indications. Neurogenic detrusor overactivity is when a knownneurologic abnormality impairs the signaling systems between the bladder and the central nervous system, and the brain is unable to inhibit the detrusormuscles controlling urination.Either party may terminate the Allergan Agreement for uncured material breach by the other party and for the insolvency of the other party. We may terminatethe Allergan Agreement if Allergan or its affiliates challenges any of our patents licensed to Allergan and such patent challenge is not required under a courtorder or subpoena and is not a defense against a claim, action or proceeding asserted by us, our affiliates or licensees against Allergan, its affiliates orsublicensees. In addition, Allergan may unilaterally terminate the Allergan Agreement for any reason upon advance notice. If Allergan has the right toterminate the Allergan Agreement due to our uncured material breach, Allergan may elect to continue the agreement and reduce all future milestone androyalty payment obligations to us by a specified percentage. In the event of any termination of the Allergan Agreement, Allergan will assign or grant a rightof reference to any regulatory documentation related to RTGel to us, all rights and licenses to Allergan will terminate, and the license Allergan granted to usunder their improvements to RTGel will continue.Intellectual PropertyOur patent estate includes patents and applications with claims directed to our MitoGel, VesiGel, RTGel, BotuGel and Vesimune product candidates, as wellas broader claims for potential future product candidates. On a worldwide basis, our patent estate includes more than 70 issued patents and pending patentapplications for our product candidates as well as for new treatment methods, manufacturing process, novel intravesical devices and systems and futurecombination products that are mainly designed to treat internal cavity cancers. In the United States, we currently have 13 issued patents and more than 45patent applications filed worldwide that are directed to methods, systems and compositions for treating internal cavity cancers, and in particular, urinary tractcancer and bladder cancer.These U.S.-issued patents are expected to remain in effect until between 2024 and 2035. Our worldwide intellectual property portfolio includes four pendingpatent applications relating to BotuGel in the European Union, China and Israel, as well as one granted patent in each of the United States and Russia. Inaddition, we have two granted patents related to Vesimune in the United States as well as two granted patents in the European Union, two granted patents inJapan, and one granted patent in each of Hong Kong and Brazil, each of which are expected to remain in effect until 2030. In addition to the issued patentsmentioned above, our portfolio includes pending patent applications relating to Vesimune in the European Union, Canada, Brazil, Hong Kong and Israel.Moreover, we hold five granted patents in the United States, four in Europe, one in each of Israel, Japan, New Zealand and Australia, as well as pending patentapplications filed worldwide that relate to novel formulations of phospholipid drug analogs (saturated lipid conjugate compositions) for the treatment ofurinary tract cancer. Our patents and patent applications mainly relate to hydrogel-based pharmaceutical compositions for optimal delivery of any drug to theinternal cavity such as a bladder and/or urinary tract; the method for treating urothelial cancer using hydrogel based composition; the method for treatingoveractive bladder topically without a need for injections; special catheters and in-dwelling ureter-catheter systems for optimal delivery of a drug into therenal cavity; pharmaceutical compositions comprising an imidazoquinolin-amine (specifically imiquimod) and lactic acid for treating bladder cancerdiseases, and novel phospholipid drug analogs for treating cancer or infections. In addition to patents, we have filed for trademark registration with theUnited States Patent and Trademark Office, or the USPTO, for “MitoGel,” “VesiGel,” “RTGel” and “BotuGel.” Furthermore, we rely upon trade secrets, know-how and continuing technological innovation to develop and maintain our competitive position. Preparing and filing patent applications is a joint endeavorof our research and development team and our in-house and external patent attorneys. Our patent attorneys conduct patent prior-art searches and then analyzethe data in order to provide our research and development team with recommendations on a routine basis. This results in: •protecting our product candidates that are under development; •encouraging pharmaceutical companies to negotiate development agreements with us; and •preventing competitors from attempting to design-around our inventions.58 We submit patent applications directly with the USPTO as provisional patent applications. We would then continue filing under the Patent CooperationTreaty, or PCT, which is an international patent law treaty that provides a unified procedure for filing a single initial patent application to seek patentprotection for an invention simultaneously in any one of the designated member states. Although a PCT application does not issue as a patent, it allows theapplicant to seek protection in any of the member states through national-phase applications.CompetitionThe standard of care for treating NMIBC patients is the TURBT procedure for tumor resection, followed by post-operative adjuvant chemotherapy orimmunotherapy instillations, administered to prevent reimplantation of the cancerous cells. The adjuvant agents used are predominately generic treatmentsand regimens. Only three drugs have been approved for the treatment of non-muscle invasive bladder cancer (NMIBC: Thiotepa, which was approved by theFDA in 1959; BCG, which was approved by the FDA in 1989; Valstar, which was approved by the FDA in 1998. Despite the approval of these drugs, thereremain high unmet needs in the bladder cancer market. BCG has been used to treat patients with CIS and high-grade T1 since 1990. Valstar is indicated forpatients with CIS (High Grade NMIBC) that do not respond to BCG treatment and Thiotepa is an over 50-year-old drug, rarely used, indicated for superficialpapillary carcinoma of the bladder. MMC is used off-label as the standard adjuvant treatment in the post-TURBT setting for low-grade NMIBC patients. Off-label means that while the FDA has not approved MMC as adjuvant treatment in the post-TURBT setting for low-grade NMIBC patients, physicians arepermitted to utilize it as standard of care for this indication as part of medical practice. However, off-label usage as a standard of care does not change theFDA’s approval criteria and does not suggest that FDA approval is more likely than for other investigational drugs. In the UTUC space, there are no approveddrugs used to treat the disease. Tumor resection surgeries are conducted in some cases of low-grade UTUC; however, complete kidney and upper urinary tractremoval is the standard of care for frequently recurring UTUC.There are several products in the development pipeline, most of which are second- or third line-treatments mainly targeted for high-grade NMIBC patientswho have failed BCG treatment. All are targeted to reduce recurrence, but none are developed to reduce the need for TURBT and other tumor resectiontherapies.We are aware that other companies, such as Roche, Vyriad, GSK, Celgene, Lipac Oncology, Samyang biopharma, Merck Sharp & Dohme Corp., Elevenbiotherapeutics, Viralytics Limited, AADi, LLC, Biocancell Ltd., Altor BioScience Corporation, FKD Therapies Oy, Spectrum Pharmaceuticals, Inc., TarisBiomedical LLC and Abnoba, are conducting or have recently conducted clinical trials for product candidates for the treatment of low-grade and high-gradeNMIBC, including CIS. In addition, we are aware of several pharmaceutical companies that are developing drug candidates for muscle-invasive bladdercancer. The FDA approved 4 immunotherapy drugs known as checkpoint inhibitors; Tecentriq (atezolizumab), Bavenico (Avelumab), Imfinzi (durbalumab)and Keytruda (pembrolizumazb) for the treatment of locally advanced or metastic baldder cancer, a form muscle invasive bladder cancer. We do not knowwhether these potential competitors are already developing, or plan to develop, low-grade UTUC or high-grade UTUC treatments or other indications that weare pursuing.In addition, we face competition from existing standards of treatment, including TURBT, which is surgery for bladder cancer. If we are not able todemonstrate that our product candidates are at least as safe and effective as such courses of treatment, medical professionals may not adopt our productcandidates to replace the existing standard of care, which is a first-line tumor surgical procedure for both bladder cancer and UTUC.The biopharmaceutical industry is intensely competitive and subject to rapid and significant technological change. Our potential competitors include largeand experienced companies that enjoy significant competitive advantages over us, such as greater financial, research and development, manufacturing,personnel and marketing resources, greater brand recognition, and more experience and expertise in obtaining marketing approvals from the FDA and foreignregulatory authorities. These companies may develop new drugs to treat the indications that we target, or seek to have existing drugs approved for use for thetreatment of the indications that we target.These potential competitors may therefore introduce competing products without our prior knowledge and without our ability to take preemptive measures inanticipation of their commercial launch. Competition may increase further as a result of advances in the commercial applicability of technologies and greateravailability of capital for investment in this industry. Our competitors may succeed in developing, acquiring or licensing on an exclusive basis products thatare more effective, easier to administer or less costly than our product candidates.Government RegulationThe FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries impose substantial requirements upon the clinicaldevelopment, manufacture and marketing of pharmaceutical products. These agencies and other federal, state and59 local entities regulate research and development activities and the testing, manufacture, quality control, safety, effectiveness, labeling, storage, packaging,recordkeeping, tracking, approval, import, export, distribution, advertising and promotion of our products.The process required by the FDA before product candidates may be marketed in the United States generally involves the following: •nonclinical laboratory and animal tests that must be conducted in accordance with good laboratory practices, or GLPs; •submission of an IND, which must become effective before clinical trials may begin; •approval by an independent institutional review board, or IRB, for each clinical site or centrally before each trial may be initiated; •adequate and well-controlled human clinical trials to establish the safety and efficacy of the proposed product candidate for its intended use,performed in accordance with good clinical practices, or GCPs; •submission to the FDA of an NDA; •satisfactory completion of an FDA advisory committee review, if applicable; •pre-approval inspection of manufacturing facilities and selected clinical investigators for their compliance with cGMP and GCPs; and •FDA approval of an NDA to permit commercial marketing for particular indications for use.Prior to the commencement of marketing of controlled substances, the U.S. Drug Enforcement Agency, or DEA, must also determine the controlled substanceschedule, taking into account the recommendation of the FDA.The testing and approval process requires substantial time, effort and financial resources. Preclinical studies include laboratory evaluation of drug substancechemistry, pharmacology, toxicity and drug product formulation, as well as animal studies to assess potential safety and efficacy. Prior to commencing thefirst clinical trial with a product candidate, we must submit the results of the preclinical tests and preclinical literature, together with manufacturinginformation, analytical data and any available clinical data or literature, among other things, to the FDA as part of an IND. Some preclinical studies maycontinue even after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day timeperiod, raises safety concerns or questions about the conduct of the clinical trial by imposing a clinical hold. In such a case, the IND sponsor and the FDAmust resolve any outstanding concerns before the clinical trial can begin. Submission of an IND may not result in FDA authorization to commence a clinicaltrial. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development, as well asamendments to previously submitted clinical trials. Further, an independent IRB for each study site proposing to conduct the clinical trial must review andapprove the plan for any clinical trial, its informed consent form and other communications to study subjects before the clinical trial commences at that site.The IRB must continue to oversee the clinical trial while it is being conducted, including any changes to the study plans. Regulatory authorities, an IRB orthe sponsor may suspend or discontinue a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to anunacceptable health risk, the clinical trial is not being conducted in accordance with the FDA’s or the IRB’s requirements, if the drug has been associatedwith unexpected serious harm to subjects, or based on evolving business objectives or competitive climate. Some studies also include a data safetymonitoring board, which receives special access to unblinded data during the clinical trial and may advise us to halt the clinical trial if it determines thatthere is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy.In general, for purposes of NDA approval, human clinical trials are typically conducted in three sequential phases that may overlap. •Phase 1—Studies are initially conducted to test the product candidate for safety, dosage tolerance, structure-activity relationships, mechanism ofaction, absorption, metabolism, distribution and excretion in healthy volunteers or subjects with the target disease or condition. If possible, Phase1 trials may also be used to gain an initial indication of product effectiveness. •Phase 2—Controlled studies are conducted with groups of subjects with a specified disease or condition to provide enough data to evaluate thepreliminary efficacy, optimal dosages and dosing schedule and expanded evidence of safety. Multiple Phase 2 clinical trials may be conducted toobtain information prior to beginning larger and more expensive Phase 3 clinical trials. •Phase 3—These clinical trials are undertaken in larger subject populations to provide statistically significant evidence of clinical efficacy and tofurther test for safety in an expanded subject population at multiple clinical trial sites. Evidence is considered to be statistically significant whenthe probability of the result occurring by random chance, rather than from the efficacy of the treatment, is sufficiently low. These clinical trials areintended to establish the overall risk/benefit ratio of the60 product and provide an adequate basis for product labeling. These trials may be done globally to support global registrations so long as the globalsites are also representative of the U.S. population and the conduct of the study at global sites comports with FDA regulations and guidance, suchas compliance with GCPs.The FDA may require, or companies may pursue, additional clinical trials after a product is approved. These so-called Phase 4 studies may be made acondition to be satisfied after approval. The results of Phase 4 studies can confirm the effectiveness of a product candidate and can provide important safetyinformation.Clinical trials must be conducted under the supervision of qualified investigators in accordance with GCP requirements, which includes the requirements thatall research subjects provide their informed consent in writing for their participation in any clinical trial, and the review and approval of the study by an IRB.Investigators must also provide information to the clinical trial sponsors to allow the sponsors to make specified financial disclosures to the FDA. Clinicaltrials are conducted under protocols detailing, among other things, the objectives of the trial, the trial procedures, the parameters to be used in monitoringsafety and the efficacy criteria to be evaluated and a statistical analysis plan. Information about some clinical trials, including a description of the trial andtrial results, must be submitted within specific timeframes to the National Institutes of Health, or NIH, for public dissemination on their ClinicalTrials.govwebsite.The manufacture of investigational drugs for the conduct of human clinical trials is subject to cGMP requirements. Investigational drugs and activepharmaceutical ingredients imported into the United States are also subject to regulation by the FDA relating to their labeling and distribution. Further, theexport of investigational drug products outside of the United States is subject to regulatory requirements of the receiving country as well as U.S. exportrequirements under the Federal Food, Drug and Cosmetic Act, or the FDCA. Progress reports detailing the results of the clinical trials must be submitted atleast annually to the FDA and the IRB and more frequently if SAEs occur.Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry andphysical characteristics of the product candidate as well as finalize a process for manufacturing the product in commercial quantities in accordance withcGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things,must develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected andtested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.505(b)(2) Regulatory Approval ProcessSection 505(b)(2) of the FDCA, or 505(b)(2), provides an alternate regulatory pathway to FDA approval for new or improved formulations or new uses ofpreviously approved drug products. Specifically, 505(b)(2) permits the filing of an NDA where at least some of the information required for approval comesfrom studies not conducted by or for the applicant and for which the applicant has not obtained a right of reference or use from the person by or for whom theinvestigations were conducted. The applicant may rely upon the FDA’s prior findings of safety and efficacy for an approved product that acts as the referencelisted drug for purposes of a 505(b)(2) NDA. The FDA may also require 505(b)(2) applicants to perform additional studies or measurements to support anychanges from the reference listed drug. The FDA may then approve the new product candidate for all or some of the labeled indications for which thereferenced product has been approved, as well as for any new indication sought by the 505(b)(2) applicant.Orange Book ListingSection 505 of the FFDCA describes three types of marketing applications that may be submitted to the FDA to request marketing authorization for a newdrug. A Section 505(b)(1) NDA is an application that contains full reports of investigations of safety and efficacy. A 505(b)(2) NDA is an application thatcontains full reports of investigations of safety and efficacy, but where at least some of the information required for approval comes from investigations thatwere not conducted by or for the applicant and for which the applicant has not obtained a right of reference or use from the person by or for whom theinvestigations were conducted. This regulatory pathway enables the applicant to rely, in part, on the FDA’s prior findings of safety and efficacy for anexisting product, or published literature, in support of its application. Section 505(j) establishes an abbreviated approval process for a generic version ofapproved drug products through the submission of an abbreviated new drug application, or ANDA. An ANDA provides for marketing of a generic drugproduct that has the same active ingredients, dosage form, strength, route of administration, labeling, performance characteristics and intended use, amongother things, to a previously approved product. ANDAs are termed “abbreviated” because they are generally not required to include preclinical and clinicaldata to establish safety and efficacy. Instead, generic applicants must scientifically demonstrate that their product is bioequivalent to, or performs in the samemanner as, the innovator drug through in vitro, in vivo or other testing. The generic version must deliver the same amount of active ingredients into asubject’s bloodstream in the same amount of time as the innovator drug and can often be substituted by pharmacists under prescriptions written for thereference listed drug.61 In seeking approval for a drug through an NDA, including a 505(b)(2) NDA, applicants are required to list with the FDA patents whose claims cover theapplicant’s product. Upon approval of an NDA, each of the patents listed in the application for the drug is then published in Approved Drug Products withTherapeutic Equivalence Evaluations, also known as the Orange Book. These products may be cited by potential competitors in support of approval of anANDA or 505(b)(2) NDA.Any applicant who submits an ANDA seeking approval of a generic equivalent version of a drug listed in the Orange Book or a 505(b)(2) NDA referencing adrug listed in the Orange Book must certify to the FDA that (1) no patent information on the drug product that is the subject of the application has beensubmitted to the FDA; (2) such patent has expired; (3) the date on which such patent expires; or (4) such patent is invalid or will not be infringed upon by themanufacture, use or sale of the drug product for which the application is submitted. This last certification is known as a Paragraph IV certification. Generally,the ANDA or 505(b)(2) NDA cannot be approved until all listed patents have expired, except where the ANDA or 505(b)(2) NDA applicant challenges a listedpatent through a Paragraph IV certification. If the applicant does not challenge the listed patents or does not indicate that it is not seeking approval of apatented method of use, the ANDA or 505(b)(2) NDA application will not be approved until all of the listed patents claiming the referenced product haveexpired.If the competitor has provided a Paragraph IV certification to the FDA, the competitor must also send notice of the Paragraph IV certification to the holder ofthe NDA for the reference listed drug and the patent owner once the application has been accepted for filing by the FDA. The NDA holder or patent ownermay then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within45 days of the receipt of a Paragraph IV certification prevents the FDA from approving the application until the earlier of 30 months from the date of thelawsuit, expiration of the patent, settlement of the lawsuit, a decision in the infringement case that is favorable to the applicant or such shorter or longerperiod as may be ordered by a court. This prohibition is generally referred to as the 30-month stay. In instances where an ANDA or 505(b)(2) NDA applicantfiles a Paragraph IV certification, the NDA holder or patent owner regularly take action to trigger the 30-month stay, recognizing that the related patentlitigation may take many months or years to resolve. Thus, approval of an ANDA or 505(b)(2) NDA could be delayed for a significant period of timedepending on the patent certification the applicant makes and the reference drug sponsor’s decision to initiate patent litigation. The applicant may also electto submit a statement certifying that its proposed label does not contain, or carves out, any language regarding the patented method-of-use rather than certifyto a listed method-of-use patent.ExclusivityThe FDA provides periods of regulatory exclusivity, which provides the holder of an approved NDA limited protection from new competition in themarketplace for the innovation represented by its approved drug for a period of three or five years following the FDA’s approval of the NDA. Five years ofexclusivity are available to NCEs. An NCE is a drug that contains no active moiety that has been approved by the FDA in any other NDA. An active moiety isthe molecule or ion, excluding those appended portions of the molecule that cause the drug to be an ester, salt, including a salt with hydrogen orcoordination bonds, or other noncovalent, or not involving the sharing of electron pairs between atoms, derivatives, such as a complex (i.e., formed by thechemical interaction of two compounds), chelate (i.e., a chemical compound), or clathrate (i.e., a polymer framework that traps molecules), of the molecule,responsible for the therapeutic activity of the drug substance. During the exclusivity period, the FDA may not accept for review or approve an ANDA or a505(b)(2) NDA submitted by another company that contains the previously approved active moiety. An ANDA or 505(b)(2) application, however, may besubmitted one year before NCE exclusivity expires if a Paragraph IV certification is filed.If a product is not eligible for the NCE exclusivity, it may be eligible for three years of exclusivity. Three-year exclusivity is available to the holder of anNDA, including a 505(b)(2) NDA, for a particular condition of approval, or change to a marketed product, such as a new formulation for a previouslyapproved product, if one or more new clinical trials, other than bioavailability or bioequivalence trials, was essential to the approval of the application andwas conducted or sponsored by the applicant. This three-year exclusivity period protects against FDA approval of ANDAs and 505(b)(2) NDAs for thecondition of the new drug’s approval. As a general matter, three-year exclusivity does not prohibit the FDA from approving ANDAs or 505(b)(2) NDAs forgeneric versions of the original, unmodified drug product. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA;however, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and adequate andwell-controlled clinical trials necessary to demonstrate safety and efficacy.The Orphan Drug ActUnder the Orphan Drug Act, the FDA may grant Orphan Drug Designation to drugs intended to treat a rare disease or condition—generally a disease orcondition that affects fewer than 200,000 individuals in the United States. Orphan Drug Designation must be requested before submitting an NDA. After theFDA grants Orphan Drug Designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. Orphan DrugDesignation does not convey any advantage in, or shorten the duration of,62 the regulatory review and approval process. The first NDA applicant to receive FDA approval for a particular active ingredient to treat a particular diseasewith FDA Orphan Drug Designation is entitled to a seven-year exclusive marketing period in the United States for that product, for that indication. During theseven-year exclusivity period, the FDA may not approve any other applications to market the same drug for the same disease, except in limitedcircumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity. Orphan drug exclusivity does not prevent FDA fromapproving a different drug for the same disease or condition, or the same drug for a different disease or condition. Among the other benefits of Orphan DrugDesignation are tax credits for certain research and a waiver of the NDA application user fee.Fast Track DesignationThe FDA is required to facilitate the development and expedite the review of drugs that are intended for the treatment of a serious or life-threateningcondition for which there is no effective treatment, and which demonstrate the potential to address unmet medical needs for the condition. Under the FastTrack program, the sponsor of a new product candidate may request the FDA to designate the product for a specific indication as a Fast Track productconcurrent with or after the submission of the IND for the product candidate. The FDA must determine if the product candidate qualifies for Fast Trackdesignation within 60 days after receipt of the sponsor’s request.For Fast Track products, the sponsor may have more frequent interactions with the FDA and the FDA may initiate review of sections of a Fast Track product’sNDA before the application is complete. This rolling review is available if the applicant provides and the FDA approves a schedule for the submission of theremaining information and the applicant pays applicable user fees. However, the FDA’s time period goal for reviewing a Fast Track application does notbegin until the last section of the NDA is submitted. In addition, the Fast Track designation may be withdrawn by the FDA if the FDA believes that thedesignation is no longer supported by data emerging in the clinical trial process. A Fast Track designated product candidate would ordinarily meet the FDA’scriteria for priority review.NDA Submission and Review by the FDAAssuming successful completion of the required clinical and preclinical testing, among other items, the results of product development, including chemistry,manufacture and controls, nonclinical studies and clinical trials are submitted to the FDA, along with proposed labeling, as part of an NDA. The submissionof an NDA requires payment of a substantial user fee to the FDA. These user fees must be paid at the time of the first submission of the application, even if theapplication is being submitted on a rolling basis. Fee waivers or reductions are available in some circumstances. One basis for a waiver of the application userfee is if the applicant employs fewer than 500 employees, including employees of affiliates, the applicant does not have an approved marketing applicationfor a product that has been introduced or delivered for introduction into interstate commerce, and the applicant, including its affiliates, is submitting its firstmarketing application.In addition, under the Pediatric Research Equity Act, or PREA, an NDA or supplement to an NDA for a new active ingredient, indication, dosage form, dosageregimen or route of administration must contain data that are adequate to assess the safety and efficacy of the drug for the claimed indications in all relevantpediatric subpopulations, and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDAmay, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after approval of the product foruse in adults or full or partial waivers from the pediatric data requirements.The FDA must refer applications for drugs that contain active ingredients, including any ester or salt of the active ingredients, that have not previously beenapproved by the FDA to an advisory committee or provide in an action letter a summary of the reasons for not referring it to an advisory committee. The FDAmay also refer drugs which present difficult questions of safety, purity or potency to an advisory committee. An advisory committee is typically a panel thatincludes clinicians and other experts who review, evaluate and make a recommendation as to whether the application should be approved and under whatconditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when makingdecisions.The FDA reviews applications to determine, among other things, whether a product is safe and effective for its intended use and whether the manufacturingcontrols are adequate to assure and preserve the product’s identity, strength, quality and purity. Before approving an NDA, the FDA will inspect the facility orfacilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities,including contract manufacturers and subcontracts, are in compliance with cGMP requirements and adequate to assure consistent production of the productwithin required specifications. Additionally, before approving an NDA, the FDA will typically inspect one or more clinical trial sites to assure compliancewith GCPs.Once the FDA receives an application, it has 60 days to review the NDA to determine if it is substantially complete to permit a substantive review, before itaccepts the application for filing. Once the submission is accepted for filing, the FDA begins an in-depth review of the NDA. The FDA’s NDA review timesmay differ based on whether the application is a standard review or priority review63 application. The FDA may give a priority review designation to drugs that are intended to treat serious conditions and provide significant improvements inthe safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions. Under the goals and policies agreed to by the FDA under thePrescription Drug User Fee Act, or PDUFA, the FDA has set the review goal of 10 months from the 60-day filing date to complete its initial review of astandard NDA for an NME and make a decision on the application. For non-NME standard applications, the FDA has set the review goal of 10 months fromthe submission date to complete its initial review and to make a decision on the application. For priority review applications, the FDA has set the review goalof reviewing NME NDAs within six months of the 60-day filing date and non-NME applications within six months of the submission date. Such deadlines arereferred to as the PDUFA date. The PDUFA date is only a goal and the FDA does not always meet its PDUFA dates. The review process and the PDUFA datemay also be extended if the FDA requests or the NDA sponsor otherwise provides additional information or clarification regarding the submission.Once the FDA’s review of the application is complete, the FDA will issue either a Complete Response Letter, or CRL, or approval letter. A CRL indicates thatthe review cycle of the application is complete, and the application is not ready for approval. A CRL generally contains a statement of specific conditionsthat must be met in order to secure final approval of the NDA and may require additional clinical or preclinical testing, or other information or analyses inorder for the FDA to reconsider the application. The FDA has the goal of reviewing 90% of application resubmissions in either two or six months of theresubmission date, depending on the kind of resubmission. Even with the submission of additional information, the FDA ultimately may decide that theapplication does not satisfy the regulatory criteria for approval. If and when those conditions have been met to the FDA’s satisfaction, the FDA may issue anapproval letter. An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications.The FDA may delay or refuse approval of an NDA if applicable regulatory criteria are not satisfied, require additional testing or information and/or requirepost-marketing testing and surveillance to monitor safety or efficacy of a product, or impose other conditions, including distribution restrictions or other riskmanagement mechanisms. For example, the FDA may require a risk evaluation and mitigation strategy, or REMS, as a condition of approval or followingapproval to mitigate any identified or suspected serious risks and ensure safe use of the drug. The FDA may prevent or limit further marketing of a product, orimpose additional post-marketing requirements, based on the results of post-marketing studies or surveillance programs. After approval, some types ofchanges to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further testingrequirements, FDA notification and FDA review and approval. Further, should new safety information arise, additional testing, product labeling or FDAnotification may be required.If regulatory approval of a product is granted, such approval may entail limitations on the indicated uses for which such product may be marketed or mayinclude contraindications, warnings or precautions in the product labeling, which has resulted in a Black Box warning. The FDA also may not approve theinclusion of labeling claims necessary for successful marketing. Once approved, the FDA may withdraw the product approval if compliance with pre- andpost-marketing regulatory standards is not maintained or if problems occur after the product reaches the marketplace. In addition, the FDA may require Phase4 post-marketing studies to monitor the effect of approved products and may limit further marketing of the product based on the results of these post-marketing studies.Post-approval RequirementsAny products manufactured or distributed by us pursuant to FDA approvals are subject to continuing regulation by the FDA, including manufacturing,periodic reporting, product sampling and distribution, advertising, promotion, drug shortage reporting, compliance with any post-approval requirementsimposed as a conditional of approval such as Phase 4 clinical trials, REMS and surveillance, recordkeeping and reporting requirements, including adverseexperiences.After approval, most changes to the approved product, such as adding new indications or other labeling claims are subject to prior FDA review and approval.There also are continuing, annual program user fee requirements for any approved products, as well as new application fees for supplemental applicationswith clinical data. Drug manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies and to listtheir drug products and are subject to periodic announced and unannounced inspections by the FDA and these state agencies for compliance with cGMPs andother requirements, which impose procedural and documentation requirements upon us and our third-party manufacturers. We cannot be certain that we orour present or future suppliers will be able to comply with the cGMP regulations and other FDA regulatory requirements.Changes to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented, or FDA notification. FDAregulations also require investigation and correction of any deviations from cGMPs and specifications 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, moneyand effort in the area of production and quality control to maintain cGMP compliance.64 Later discovery of previously unknown problems with a product, including AEs of unanticipated severity or frequency, or with manufacturing processes, orfailure to comply with regulatory requirements, may result in withdrawal of marketing approval, mandatory revisions to the approved labeling to add newsafety information or other limitations, imposition of post-market studies or clinical trials to assess new safety risks, or imposition of distribution or otherrestrictions under a REMS program, among other consequences.The FDA closely regulates the marketing and promotion of drugs. A company can make only those claims relating to safety and efficacy, purity and potencythat are approved by the FDA. Physicians, in their independent professional medical judgement, may prescribe legally available products for uses that are notdescribed in the product’s labeling and that differ from those tested by us and approved by the FDA. We, however, are prohibited from marketing orpromoting drugs for uses outside of the approved labeling.In addition, the distribution of prescription pharmaceutical products, including samples, is subject to the Prescription Drug Marketing Act, or PDMA, whichregulates the distribution of drugs and drug samples at the federal level, and sets minimum standards for the registration and regulation of drug distributors bythe states. Both the PDMA and state laws limit the distribution of prescription pharmaceutical product samples and impose requirements to ensureaccountability in distribution. The Drug Supply Chain Security Act also imposes obligations on manufacturers of pharmaceutical products related to productand tracking and tracing.Failure to comply with any of the FDA’s requirements could result in significant adverse enforcement actions. These include a variety of administrative orjudicial sanctions, such as refusal to approve pending applications, license suspension or revocation, withdrawal of an approval, imposition of a clinical holdor termination of clinical trials, warning letters, untitled letters, cyber letters, modification of promotional materials or labeling, product recalls, productseizures or detentions, refusal to allow imports or exports, total or partial suspension of production or distribution, debarment, injunctions, fines, consentdecrees, corporate integrity agreements, refusals of government contracts and new orders under existing contracts, exclusion from participation in federal andstate healthcare programs, restitution, disgorgement or civil or criminal penalties, including fines and imprisonment. Any of these sanctions could result inadverse publicity, among other adverse consequences.Other Healthcare RegulationsOur business activities, including but not limited to, research, sales, promotion, distribution, medical education and other activities following productapproval will be subject to regulation by numerous regulatory and law enforcement authorities in the United States in addition to the FDA, includingpotentially the Department of Justice, the Department of Health and Human Services and its various divisions, including the CMS and the Health Resourcesand Services Administration, the Department of Veterans Affairs, the Department of Defense and state and local governments. Our business activities mustcomply with numerous healthcare laws and regulations, including those described below.The federal Anti-Kickback Statute prohibits, among other things, any person or entity, from knowingly and willfully offering, paying, soliciting or receivingany remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward, or in return for, the referral of an individual for, orpurchasing, leasing, ordering, or arranging for the purchase, lease or order of, any good, facility, item or service reimbursable, in whole or in part, byMedicare, Medicaid or other federal healthcare programs. The term remuneration has been interpreted broadly to include anything of value, includingunlawful financial inducements paid to prescribers and beneficiaries, as well as impermissible promotional practices. There are a number of statutoryexceptions and regulatory safe harbors protecting some common activities from prosecution, but the exceptions and safe harbors are drawn narrowly. Failureto meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under thefederal Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all of itsfacts and circumstances. Additionally, the Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education ReconciliationAct of 2010, or collectively the ACA, amended the intent requirement of the federal Anti-Kickback Statute so that a person or entity no longer needs to haveactual knowledge of the federal Anti-Kickback Statute, or the specific intent to violate it, to have violated the statute. The ACA also provided that a violationof the federal Anti-Kickback Statute is grounds for the government or a whistleblower to assert that a claim for payment of items or services resulting fromsuch violation constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act.The federal civil and criminal false claims laws, including the federal False Claims Act, prohibit, among other things, any person or entity from knowinglypresenting, or causing to be presented, a false claim for payment to, or for approval by, the federal government, including the Medicare and Medicaidprograms, or knowingly making, using, or causing to be made or used a false record or statement material to a false or fraudulent claim to avoid, decrease orconceal an obligation to pay money to the federal government.The civil monetary penalties statute imposes penalties against any person or entity who, among other things, is determined to have presented or caused to bepresented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false orfraudulent.65 As a condition of receiving Medicaid coverage for prescription drugs, the Medicaid Drug Rebate Program requires manufacturers to calculate and report toCMS their Average Manufacturer Price, or AMP, which is used to determine rebate payments shared between the states and the federal government and, forsome multiple source drugs, Medicaid payment rates for the drug, and for drugs paid under Medicare Part B, to also calculate and report their average salesprice, which is used to determine the Medicare Part B payment rate for the drug. In January 2016, CMS issued a final rule regarding the Medicaid DrugRebate Program, effective April 1, 2016, that, among other things, revises the manner in which the AMP is to be calculated by manufacturers participating inthe program and implements certain amendments to the Medicaid rebate statute created under the ACA. Drugs that are approved under a biologics licenseapplication, or BLA, or an NDA, including a 505(b)(2) NDA, are subject to an additional requirement to calculate and report the manufacturer’s best price forthe drug and inflation penalties which can substantially increase rebate payments. For BLA and NDA drugs, the Veterans Health Care Act requiresmanufacturers to calculate and report to the Department of Veterans Affairs a different price called the Non-Federal AMP, offer the drugs for sale on theFederal Supply Schedule, and charge the government no more than a statutory price referred to as the Federal Ceiling Price, which includes an inflationpenalty. A separate law requires manufacturers to pay rebates on these drugs when paid by the Department of Defense under its TRICARE Retail PharmacyProgram. Knowingly submitting false pricing information to the government creates potential federal False Claims Act liability.The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created additional federal criminal statutes that prohibit knowingly andwillfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including public and private payors, or obtain, by meansof false or fraudulent pretenses, representations or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefitprogram, regardless of whether the payor is public or private, knowingly and willfully embezzling or stealing from a health care benefit program, willfullyobstructing a criminal investigation of a health care offense and knowingly and willfully falsifying, concealing or covering up by any trick or device amaterial fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating tohealthcare matters. The ACA amended the federal health care fraud criminal statute implemented under HIPAA so that a person or entity no longer needs tohave actual knowledge of the statute, or the specific intent to violate it, to have violated the statute.Additionally, the federal Open Payments program pursuant to the Physician Payments Sunshine Act, created under Section 6002 of the ACA and itsimplementing regulations, require some manufacturers of drugs, devices, biologicals and medical supplies for which payment is available under Medicare,Medicaid or the Children’s Health Insurance Program (with specified exceptions) to report annually information related to specified payments or othertransfers of value provided to physicians and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians andteaching hospitals and to report annually specified ownership and investment interests held by physicians and their immediate family members.In addition, we may be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business.HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their implementing regulations, imposerequirements relating to the privacy, security and transmission of individually identifiable health information on HIPAA covered entities and their businessassociates, including mandatory contractual terms and the implementation of certain safeguards of such information. Among other things, HITECH makesHIPAA’s security standards directly applicable to business associates, independent contractors or agents of covered entities that receive or obtain protectedhealth information in connection with providing a service on behalf of a covered entity. HITECH also created four new tiers of civil monetary penalties,amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civilactions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civilactions. In addition, state laws govern the privacy and security of health information in some circumstances, many of which differ from each other insignificant ways, may not have the same effect and may not be preempted by HIPAA, thus complicating compliance efforts.Many states have also adopted laws similar to each of the above federal laws, which may be broader in scope and apply to items or services reimbursed byany payor, including commercial insurers. We may also be subject to state laws that require pharmaceutical companies to comply with the pharmaceuticalindustry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, and/or state laws that requiredrug manufacturers to report information related to marketing expenditures or payments and other transfers of value to physicians and other healthcareproviders.Enforcement actions can be brought by federal or state governments or, in some cases, as “qui tam” actions brought by individual whistleblowers in the nameof the government. Depending on the circumstances, failure to comply with these laws can result in penalties, including criminal, civil and/or administrativecriminal penalties, damages, fines, disgorgement, debarment from government contracts, individual imprisonment, additional reporting requirements andoversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, exclusionfrom government programs, refusal to allow us to enter into supply contracts, including government contracts, reputational harm, diminished profits andfuture earnings and the curtailment or restructuring of our operations, any of which could adversely affect our business.66 Coverage and ReimbursementOur ability to commercialize any products successfully also will depend in part on the extent to which coverage and adequate reimbursement for ourproducts, once approved, and related treatments will be available from third-party payors, such as government health administration authorities, privatehealth insurers and managed care organizations. Third-party payors determine which medications they will cover and separately establish reimbursementlevels. Even if we obtain coverage for a given product by a third-party payor, the third-party payor’s reimbursement rates may not be adequate to make theproduct affordable to patients or profitable to us, or the third-party payors may require co-payments that patients find unacceptably high. Patients who areprescribed medications for the treatment of their conditions, and their prescribing physicians, generally rely on third-party payors to reimburse all or part ofthe costs associated with their prescription drugs. Patients are unlikely to use our products unless coverage is provided, and reimbursement is adequate tocover all or a significant portion of the cost of our products. Therefore, coverage and adequate reimbursement is critical to new product acceptance. Coveragedecisions may depend upon clinical and economic standards that disfavor new drug products when more established or lower cost therapeutic alternatives arealready available or subsequently become available.Government authorities and other third-party payors are developing increasingly sophisticated methods of controlling healthcare costs, such as by limitingcoverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that drug companies provide them withpredetermined discounts from list prices as a condition of coverage, are using restrictive formularies and preferred drug lists to leverage greater discounts incompetitive classes and are challenging the prices charged for medical products. Further, no uniform policy for determining coverage and reimbursement fordrug products exists among third-party payors in the United States. Therefore, coverage and reimbursement for drug products can differ significantly frompayor to payor. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific andclinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be appliedconsistently or obtained in the first instance.We cannot be sure that coverage and reimbursement will be available for any product that we commercialize and, if reimbursement is available, that the levelof reimbursement will be adequate. Coverage and reimbursement may impact the demand for, or the price of, any product candidate for which we obtainmarketing approval. If coverage and reimbursement are not available, or if reimbursement is available only to limited levels, we may not successfullycommercialize any product candidate for which we obtain marketing approval.Healthcare Reform MeasuresThe United States and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals designed to change thehealthcare system in ways that could affect our ability to sell our products profitably. Among policy makers and payors in the United States and elsewhere,there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/orexpanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by majorlegislative initiatives.For example, in March 2010, the ACA was passed, which is changing health care financing by both governmental and private insurers and significantlyaffecting the U.S. pharmaceutical industry. The ACA, among other things, subjected manufacturers to new annual fees and taxes for specified brandedprescription drugs, increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program, expanded health carefraud and abuse laws, revised the methodology by which rebates owed by manufacturers to the state and federal government for covered outpatient drugsunder the Medicaid Drug Rebate Program are calculated, imposed an additional rebate similar to an inflation penalty on new formulations of drugs, extendedthe Medicaid Drug Rebate Program to Medicaid managed care organizations, expanded the 340B program, which caps the price at which manufacturers cansell covered outpatient pharmaceuticals to specified hospitals, clinics and community health centers, and provided incentives to programs that increase thefederal government’s comparative effectiveness research. However, some provisions of the ACA have yet to be fully implemented and certain provisions have been subject to judicial and Congressional challenges,as well as efforts by the Trump Administration to repeal or replace certain aspects of the ACA. For example, since January 2017, President Trump has signedtwo executive orders and other directives designed to delay, circumvent, or loosen certain requirements mandated by the ACA. Concurrently, Congress hasconsidered legislation that would repeal or repeal and replace all or part of the ACA. The recently enacted Tax Cuts and Jobs Act also includes a provisionthat repeals, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintainqualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” Additionally, on January 22, 2018, PresidentTrump signed a continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain ACA-mandated fees, including theso-called “Cadillac” tax on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based onmarket share, and the medical device excise tax on non-exempt medical devices. Further, the Bipartisan Budget Act of 2018, or the BBA, among other things,amends the ACA, effective January 1, 2019, to67 close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole.” We continue to evaluate how the ACA and recent efforts torepeal and replace or limit the implementation of the ACA will impact our business. We continue to evaluate how the ACA and recent efforts to repeal andreplace or limit the implementation of the ACA will impact our business.Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. In August 2011, the Budget Control Act of 2011,among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending atargeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’sautomatic reduction to several government programs. This includes aggregate reductions of Medicare payments to providers up to 2% per fiscal year, whichwent into effect in April 2013 and, due to subsequent legislative amendments to the statute, including the BBA, will remain in effect through 2027 unlessadditional U.S. Congressional action is taken. In addition, in January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012,which, among other things, reduced Medicare payments to several categories of healthcare providers and increased the statute of limitations period for thegovernment to recover overpayments to providers from three to five years. Further, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, therehave been several recent U.S. Congressional inquiries and proposed and enacted legislation at the federal and state levels designed to, among other things,bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost of drugs underMedicare, and reform government program reimbursement methodologies for drugs. At the federal level, the Trump Administration’s budget proposal forfiscal year 2019 contains further drug price control measures that could be enacted during the 2019 budget process or in other future legislation, including,for example, measures to permit Medicare Part D plans to negotiate the price of certain drugs under Medicare Part B, to allow some states to negotiate drugprices under Medicaid, and to eliminate cost sharing for generic drugs for low-income patients. While any proposed measures will require authorizationthrough additional legislation to become effective, Congress and the Trump Administration have both stated that it will continue to seek new legislativeand/or administrative measures to control drug costs. At the state level, legislatures have been increasingly passing legislation and implementing regulationsdesigned to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certainproduct access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries andbulk purchasing. Additional health reform measures may continue and affect our business in unknown ways.The Foreign Corrupt Practices ActThe Foreign Corrupt Practices Act, or FCPA, prohibits any U.S. individual or business from paying, offering or authorizing payment or offering of anything ofvalue, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign entity in orderto assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the United States tocomply with accounting provisions requiring the companies to maintain books and records that accurately and fairly reflect all transactions of the companies,including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations.Foreign RegulationIn addition to regulations in the United States, we will be subject to a variety of foreign regulations governing clinical trials and commercial sales anddistribution of our products to the extent we choose to develop or sell any products outside of the United States. The approval process varies from country tocountry and the time may be longer or shorter than that required to obtain FDA approval. The requirements governing the conduct of clinical trials, productlicensing, pricing and reimbursement vary greatly from country to country.Manufacturing, Supply and ProductionWe do not own or operate manufacturing facilities for the production of our product candidates, nor do we have plans to develop our own manufacturingoperations in the foreseeable future. We currently rely on third-party contract manufacturers for all of our required raw materials, active ingredients andfinished products for our preclinical research and clinical trials, including the single pivotal Phase 3 clinical trial for MitoGel. We do not have long-termagreements with any of these third parties. We also do not have any current contractual relationships for the manufacture of commercial supplies of ourproduct candidates if they are approved. If product candidates are approved by any regulatory agency, we intend to enter into agreements with a third-partycontract manufacturer and one or more back-up manufacturers for the commercial production of those products.Development and commercial quantities of any products that we develop will need to be manufactured in facilities, and by processes, that comply with therequirements of the FDA and the regulatory agencies of other jurisdictions in which we are seeking approval. We currently employ internal resources tomanage our manufacturing contractors. The relevant manufacturers of our drug products for our current preclinical and clinical trials have advised us thatthey are compliant with both current good laboratory practice, or cGLP, and cGMP.68 Our product candidates, if approved, may not be producible in sufficient commercial quantities, in compliance with regulatory requirements or at anacceptable cost. We and our contract manufacturers are, and will be, subject to extensive governmental regulation in connection with the manufacture of anypharmaceutical products or medical devices. We and our contract manufacturers must ensure that all of the processes, methods and equipment are compliantwith cGMP and cGLP for drugs on an ongoing basis, as mandated by the FDA and foreign regulatory authorities, and conduct extensive audits of vendors,contract laboratories and suppliers.Marketing, Sales and DistributionGiven our stage of development, we do not have any internal sales, marketing or distribution infrastructure or capabilities, and our marketing departmentcurrently consists only of a marketing director, whose main responsibility is to produce marketing and communication materials, exhibitions, website contentand to identify unmet needs in the urology market, assess their commercial potential and advise on the prioritization of the development of our futureproduct candidates accordingly. We have recently formed a U.S. subsidiary, Urogen Pharma, Inc., to support our U.S. development and potentialcommercialization efforts.In the event that we receive regulatory approvals for our products in markets outside of the United States, we intend, where appropriate, to pursuecommercialization relationships, including strategic alliances and licensing, with pharmaceutical companies and other strategic partners, which are equippedto market or sell our products through their well-developed sales, marketing and distribution organizations in such countries.In addition, we may out-license some or all of our worldwide patent rights to more than one party to achieve the fullest development, marketing anddistribution of any products we develop.C.Organizational structure.Urogen Pharma, Inc., our wholly owned subsidiary, was incorporated under the laws of the State of Delaware in October 2015.D.Property, plants and equipment.Our principal executive offices are located at 9 HaTa’asiya St., Ra’anana 4365007, Israel, where we lease an approximately 11,495 square foot facility. ThisIsraeli facility houses our administrative headquarters and our research and development laboratories. We also maintain an office at 499 Park Avenue, NewYork, New York, where we lease approximately 9,336 square feet of space, which serves as the headquarters for our U.S. subsidiary. We believe that ourexisting facilities are adequate to meet our current needs, and that suitable additional or alternative spaces will be available in the future on commerciallyreasonable terms.Item 4A. Unresolved Staff CommentsNot applicable.Item 5. Operating and Financial Review and ProspectsA.Operating results.OverviewWe are a clinical stage biopharmaceutical company focused on developing novel therapies designed to change the standard of care for urologicalpathologies. We have an innovative and broad pipeline of product candidates that we believe can overcome the deficiencies of current treatment options fora variety of urological conditions with a focus on uro-oncology. Our lead product candidates, MitoGel and VesiGel, are proprietary formulations of thechemotherapy drug Mitomycin C, or MMC, a generic drug, which is currently used off-label for urothelial cancer treatment only in a water-based formulationas an adjuvant, or supplemental post-surgery, therapy. We are developing our product candidates as chemoablation agents, which means they are designed toremove tumors by non-surgical means, to treat several forms of non-muscle invasive urothelial cancer, including low-grade upper tract urothelial carcinoma,or UTUC, and low-grade bladder cancer. We believe that MitoGel and VesiGel, which are both local drug therapies, have the potential to significantlyimprove patients’ quality of life by replacing costly, sub-optimal and burdensome tumor resection and kidney removal surgeries as the first-line standard ofcare. MitoGel and VesiGel may also reduce the need for bladder and upper urinary tract surgeries, including removal of the upper urinary tract, which aremajor surgical procedures typically performed when local endoscopic tumor resection fails to control the disease progression. Additionally, we believe thatour product candidates, which are based on formulations of previously approved drugs, may qualify for streamlined regulatory pathways to market approval.69 Our lead product candidates, MitoGel and VesiGel, are formulated using our proprietary reverse thermally triggered hydrogel, or RTGel, technology. Webelieve that RTGel-based drug formulations, which provide for the sustained release of an active drug, may improve the efficacy of treatment of various typesof urothelial cancer without compromising the safety of the patient or interfering with the natural flow of fluids from the urinary tract to the bladder. Ourformulations are designed to achieve this by increasing the dwell time as well as the tissue coverage of the active drug throughout the organ. Consequently,we believe that RTGel-based drug formulations may enable us to overcome the anatomical and physiological challenges that have historically contributed tothe lack of drug development for the treatment of urothelial cancer. No drugs have been approved by the U.S. Food and Drug Administration, or the FDA, forthe treatment of non-muscle invasive bladder cancer, or NMIBC, in more than 15 years.Our clinical stage pipeline also includes Vesimune, our proprietary immunotherapy product candidate for the treatment of high-grade NMIBC, which mayinclude Carcinoma in Situ, or CIS. Vesimune is a novel, liquid formulation of Imiquimod, a generic toll-like receptor 7, or TLR7, agonist. Toll-like receptoragonists play a key role in initiating the innate immune response system. We believe that the combination of Vesimune with additional immunotherapydrugs, such as immune checkpoint inhibitors or chemotherapy drugs like VesiGel, could represent a valid alternative to the current standard of care for thepost-TURBT adjuvant treatment of high-grade NMIBC.BotuGel is our proprietary novel RTGel-based formulation of BOTOX, a branded drug, that we believe can potentially serve as an effective treatment optionfor patients suffering from overactive bladder. In October 2016, we announced the licensing of the worldwide rights to RTGel in combination withneurotoxins, including BOTOX, to Allergan Pharmaceuticals International Limited, or Allergan, a wholly owned subsidiary of Allergan plc, or the AllerganAgreement. In August 2017, we announced that Allergan had submitted an IND to the FDA in order to be able to commence clinical trials in the United Statesusing the RTGel in combination with BOTOX. In October 2017, Allergan commenced a Phase 2 clinical trial of BotuGel for the treatment of overactivebladder.We have incurred net losses in each period since our formation in 2004. We incurred net losses of $20.0 million, $1.9 million and $12.7 million for the yearsended December 31, 2017, 2016 and 2015, respectively. As of December 31, 2017 our accumulated deficit was $47.2 million. We expect to continue to incurlosses for the foreseeable future, and our losses may fluctuate significantly from year to year. We expect that our expenses will increase substantially inconnection with our ongoing activities as we: •conduct the single pivotal Phase 3 clinical trial for MitoGel, and plan to initiate a Phase 2b clinical trial for VesiGel, each pursuant to the FDA’s505(b)(2) regulatory pathway; •initiate an additional clinical trial for Vesimune in combination with another agent; •continue the preclinical development of our other product candidates; •submit an NDA seeking regulatory approval for any product candidates; •establish a sales, marketing and distribution infrastructure and scale up external manufacturing capabilities to commercialize any products forwhich we obtain regulatory approval; •maintain, expand and protect our intellectual property portfolio; •add equipment and physical infrastructure to support our research and development; •hire additional clinical development, regulatory, commercial, quality control and manufacturing personnel; and •add operational, financial and management information systems and personnel, including personnel to support our product development andplanned future commercialization.We will need substantial additional funding to support our operating activities as we advance our product candidates through clinical development, seekregulatory approval and prepare for and, if any of our product candidates are approved, proceed to commercialization. Adequate funding may not beavailable to us on acceptable terms, or at all.Allergan License AgreementWe entered into an exclusive license agreement with Allergan Pharmaceuticals International Limited, or Allergan, a wholly owned subsidiary of Allergan plcin October 2016, which we refer to as the Allergan Agreement. Allergan paid us a nonrefundable upfront license fee of $17.5 million, and we are eligible toreceive additional milestone payments upon the successful completion of certain development, regulatory and commercial milestones. Under the AllerganAgreement, Allergan is solely responsible, at its expense, for developing, obtaining regulatory approvals for and commercializing, on a worldwide basis,pharmaceutical products that contain RTGel and clostridial toxins (including BOTOX), alone or in combination with certain other active ingredients, whichwe refer to collectively as the Licensed Products. Allergan is obligated to pay us a tiered royalty in the low single digits based on worldwide70 annual net sales of Licensed Products, subject to certain reductions for the market entry of competing products and/or loss of our patent coverage of LicensedProducts. We are responsible for payments to any third party for certain RTGel-related third party intellectual properties. In July 2017, Allergan notified usthat they had submitted their Investigational New Drug, or IND, application for BotuGel, our proprietary novel RTGel-based formulation of BOTOX for thetreatment of overactive bladder, to the FDA. The submission of the IND triggered the second milestone under the Allergan Agreement, pursuant to which wereceived a payment of $7.5 million in August 2017. Allergan commenced a Phase 2 clinical trial of BotuGel in October 2017, pursuant to AllerganAgreement.Components of Results of OperationsRevenuesWe do not currently have any products approved for sale and, to date, we have not recognized any revenues from sales of MitoGel, VesiGel or Vesimune.During the year ended December 31, 2016, we recognized revenues of $17.5 million from a payment received under the Allergan Agreement. For the yearended December 31, 2017, we recognized revenues of $7.5 million under the Allergan Agreement upon the achievement of a milestone in August 2017. Theremaining revenues we recognized during the year ended December 31, 2017 are related to sales of RTGel to Allergan, per the Allergan Agreement. In thefuture, we may generate revenue from a combination of product sales, reimbursements, up-front payments, milestone payments and royalties in connectionwith the Allergan Agreement and future collaborations. If we fail to achieve clinical success and/or to obtain regulatory approval of any of our productcandidates in a timely manner, our ability to generate future revenue will be impaired.Operating expensesResearch and development expenses, netThe largest component of our total operating expenses has historically been, and we expect will continue to be, research and development. Research anddevelopment expenses consist primarily of: •salaries and related costs, including share-based compensation expense, for our personnel in research and development functions; •expenses incurred under agreements with third parties, including CROs, subcontractors, suppliers and consultants, preclinical studies and clinicaltrials; •expenses incurred to acquire, develop and manufacture preclinical study and clinical trial materials; and •facility and equipment costs, including depreciation expense, maintenance and allocated direct and indirect overhead costs.We expense all research and development costs as incurred. In light of the fact that our employees and internal resources may be engaged in projects formultiple programs at any time, our focus is on total research and development expenditures, and we do not allocate our internal research and developmentexpenses by project.Through December 31, 2017, we had received grants of $2.1 million in the aggregate from the Israeli Innovation Authority, or the IIA, for research anddevelopment funding. Pursuant to the terms of the grants, we are obligated to pay the IIA royalties of 3.0% to 4.5% on revenues from sales of productsdeveloped from a project financed in whole or in part by IIA grants, up to a limit of 100% of the amount of the grant received, plus annual interest calculatedat a rate based on 12-month LIBOR.In addition to paying any royalties due, we must abide by other restrictions associated with receiving such grants under the R&D Law, which will continue toapply to us following full repayment to the IIA. For example, under the Allergan Agreement, Allergan has the option to manufacture products developed withIIA-funded technology outside of Israel, which would require approval from the IIA. Although Allergan has not yet exercised this option, we have requestedapproval from the IIA for a possible transfer. We may not receive such approval. Even if we do receive such approval, we may be required to pay increasedroyalties of up to 300% of the amount of the original grant received and other amounts. If the IIA deems the license to Allergan a technology transfer, we maybe required to pay up to 600% of the amount of the original grant and other amounts. The Israeli government grants we have received for research anddevelopment activities restrict our ability to manufacture products and transfer technologies outside of Israel and require us, in addition to the payment ofroyalties, to satisfy specified conditions. If we fail to satisfy these conditions, we may be required to refund grants previously received and incur financialpenalties.71 In June 2017, new rules published by the IIA for granting a right to use know- how developed from research and development that was conducted pursuant toa plan approved by the IIA outside of Israel, or Licensing Rules, came into effect. The Licensing Rules allow a recipient of a grant from the IIA to grant thirdparties outside of Israel the right to use know-how, or License, provided that the IIA authorized the grant of the License. In such case, the recipient of thegrant has to pay the IIA for the License. The amount of payment is based on various factors, including the consideration received by the licensor and, inaccordance with the formulas set forth in the Licensing Rules, may equal up to six times the IIA-funding amount plus interest. When the consideration for thegrant includes nonmonetary compensation or monetary compensation that is not fixed, or when a “special relationship” exists between the licensor andlicensee (e.g., when a party controls the other party or is the other party’s exclusive distributor) or when the agreed consideration does not reflect, in the IIA’sopinion, the market value, the IIA may base the value of the transaction on an economic assessment that it obtains for such purpose.We are currently focused on advancing our product candidates, and our future research and development expenses will depend on their clinical success.Research and development expenses will continue to be significant and will increase over at least the next several years as we continue to develop ourproduct candidates and conduct preclinical studies and clinical trials of our product candidates.We do not believe that it is possible at this time to accurately project total expenses required for us to reach commercialization of our product candidates.Due to the inherently unpredictable nature of preclinical and clinical development, we are unable to estimate with certainty the costs we will incur and thetimelines that will be required in the continued development and approval of our product candidates. Clinical and preclinical development timelines, theprobability of success and development costs can differ materially from expectations. In addition, we cannot forecast which product candidates may besubject to future collaborations, if and when such arrangements will be entered into, if at all, and to what degree such arrangements would affect ourdevelopment plans and capital requirements.Under applicable accounting rules, we deduct the IIA grants from research and development expenses as the applicable costs are incurred. We also had apreclinical collaboration for BotuGel with Allergan into which we initially entered into in February 2014. We deduct amounts received from the preclinicalcollaboration with Allergan from our research and development expenses as the applicable costs are incurred. As a result, our research and developmentexpenses are shown on our financial statements net of the IIA grants and amounts received from the preclinical collaboration.General and administrative expensesGeneral and administrative expenses consist primarily of personnel costs, including share-based compensation, related to directors, executive, finance, andhuman resource functions, facility costs and external professional service costs, including legal, accounting and audit services and other consulting fees.We anticipate that our general and administrative expenses will increase in the future as we increase our administrative headcount and infrastructure tosupport our continued research and development programs and the potential approval and commercialization of our product candidates. We also anticipatethat we will incur increased expenses related to audit, legal, regulatory and tax-related services associated with maintaining compliance with Nasdaq andSEC requirements, director and officer insurance premiums, executive compensation, and other costs associated with being a public company.In addition, if any of our product candidates receives regulatory approval and if we invest in building a commercial infrastructure to support the marketing ofour products, we expect to incur greater expenses.Finance expenses, netFinance expenses, net, consisted primarily of finance expenses on warrants offset by interest income.Income taxesWe have yet to generate taxable income in Israel. We have historically incurred operating losses resulting in carry forward tax losses totaling approximately$24.8 million as of December 31, 2017. We anticipate that we will continue to generate tax losses for the foreseeable future and that we will be able to carryforward these tax losses indefinitely to future taxable years. Accordingly, we do not expect to pay taxes in Israel until we have taxable income after the fullutilization of our carry forward tax losses. We have provided a full valuation allowance with respect to the deferred tax assets related to these carry forwardlosses.72 Analysis of Results of OperationsComparison of the years ended December 31, 2017, 2016 and 2015The following table summarizes our results of operations for the years ended December 31, 2017, 2016 and 2015: Year Ended December 31, 2017 2016 2015 (in thousands) Revenues $8,158 $17,530 $— Cost of revenues 600 28 — Gross profit 7,558 17,502 — Research and development expenses, net(1) 18,697 10,287 10,515 General and administrative expenses(1) 8,811 6,417 1,895 Operating (loss) income (19,950) 798 (12,410)Finance expenses, net 31 2,739 279 Loss before income taxes (19,981) (1,941) (12,689)Income tax expense 19 — — Net loss $(20,000) $(1,941) $(12,689) (1)Includes share-based compensation expense as follows: Year Ended December 31, 2017 2016 2015 (in thousands) Research and development expenses, net $3,923 $1,167 $170 General and administrative expenses 2,377 800 279 Total share-based compensation $6,300 $1,967 $449 Total share-based compensation expense increased $4.3 million in 2017 over 2016 due to an increase in the fair market value of our share price for 2017grants and modifications associated with our IPO. Years Ended December 31, 2017 and 2016 RevenuesOur total revenues decreased by $9.3 million to $8.2 million in the year ended December 31, 2017 from $17.5 million in the year ended December 31, 2016.This decrease is mainly due to the difference in proceeds of $7.5 million and $17.5 million received from Allergan upon the achievement of certainmilestones under the Allergan Agreement in each of the years ended December 31, 2017 and 2016, respectively.Operating expensesResearch and development expensesResearch and development expenses increased by $8.4 million to $18.7 million in the year ended December 31, 2017 from $10.3 million in the year endedDecember 31, 2016. The increase was attributable mainly to an increase in direct costs associated with the MitoGel Phase 3 clinical trial of approximately$3.1 million, an increase of approximately $2.8 million of share-based compensation expenses related to an increase in personnel and the grant date fairvalue of common stock, and an increase of approximately $2.5 million in headcount, consulting and related costs to support increased clinical trial activities.Total non-cash research and development share-based compensation expense for the year ended December 31, 2017 was $3.9 million.General and administrative expensesGeneral and administrative expenses increased by approximately $2.4 to $8.8 million in the year ended December 31, 2017 from $6.4 million in the yearended December 31, 2016. The increase in general and administrative expenses resulted primarily from an increase in share-based compensation expense ofapproximately $1.6 million related to an increase in personnel and the grant date fair value of73 common stock, an increase of $1.3 million in payroll and recruitment costs due to headcount and related costs to support our growing business, an increase of$0.9 million in professional service expenses, commercial services, director and officer insurance premiums, and other costs associated with being a publiccompany, and an increase of $0.3 million in rent and office maintenance related to our new office in New York. These increases were offset by $1.7 million ofIPO expenses in the statement of operations in 2016. Total non-cash general and administrative share-based compensation expense for the year endedDecember 31, 2017 was $2.4 million.Finance expenses, netFinance expenses, net, decreased by approximately $2.7 million to less than $1,000 in the year ended December 31, 2017 from $2.7 million in the year endedDecember 31, 2016. The change in finance expenses, net, was primarily due to the recording of the increased fair value of the warrants to the incomestatement in 2016. The warrants converted to Preferred A-1 shares upon the close of the IPO in May 2017. There was minimal change in the fair value of thewarrants in 2017 prior to conversion.Years Ended December 31, 2016 and 2015RevenuesOur total revenues increased by $17.5 million from $0 in the year ended December 31, 2015 to $17.5 million in the year ended December 31, 2016, due tothe nonrefundable upfront license fee received under the Allergan Agreement.Operating expensesResearch and development expensesResearch and development expenses decreased by $228,000, or 2%, to $10.3 million in the year ended December 31, 2016 from $10.5 million in the yearended December 31, 2015. Approximately $4.1 million of the decrease relates to in-process research and development costs in connection with intellectualproperty related to Vesimune that we purchased from Telormedix SA in 2015. This decrease is partly offset by an increase of $3.9 million primarilyattributable to an increase in share-based compensation to consultants and employees of $997,000, an increase of $546,000 in payroll mainly due toincreased headcount and a $1.2 million increase relating to research and development expense offsets in 2015 from IIA grants and from our prior preclinicalcollaboration with Allergan for BotuGel.General and administrative expensesGeneral and administrative expenses increased by $4.5 million, or 237%, to $6.4 million in the year ended December 31, 2016 from $1.9 million in the yearended December 31, 2015. The increase in general and administrative expenses resulted primarily from an increase in share-based compensation expenses toemployees and directors of $521,000, an increase of $773,000 in payroll and an increase in professional services expenses of $2.8 million of which $1.7million relates to this offering. The increase was primarily related to our strengthening of our senior management team and payments to professional servicesconsultants hired by us in preparation for this offering.Finance expenses, netFinance expenses, net, increased by $2.4 million to $2.7 million in the year ended December 31, 2016 from $0.3 million in the year ended December 31,2015. The change in finance expense was primarily due to the increased fair value of the warrants converted to Series A-1 preferred shares.For a discussion of Foreign currency exchange risk, see “Item 11— Quantitative and Qualitative Disclosures About Market Risk.”B.Liquidity and capital resources.LiquiditySince our inception, we have incurred losses and negative cash flows from our operations. For the year ended December 31, 2017, we incurred a net loss of$20.0 million while net cash of $9.6 million was used in our operating activities and $61.6 million was provided by our financing activities. As of December31, 2017, we had working capital of $67.4 million, and an accumulated deficit of $47.2 million. Our principal source of liquidity as of December 31, 2017consisted of cash and cash equivalents of $37 million and short-74 term investments of $36.0 million, all of which is held in U. S. dollars We believe that our existing cash, cash equivalents and short-term investments willenable us to fund our operating and capital expenditure requirements for at least the next 12 months.Capital resourcesOverviewThrough December 31, 2017, we financed our operations primarily through public equity offerings, private placements of equity securities and through theupfront payment received under the Allergan Agreement. In May 2017, we raised $60.8 million, net of issuance costs and underwriting discounts andcommissions, in our IPO on the Nasdaq Stock Market. In August 2017, we received $7.5 million from Allergan upon the achievement of a milestone underthe Allergan Agreement. In addition, during the year ended December 31, 2016, we recorded $1.7 million in general and administrative expenses related toIPO costs, in accordance with SEC staff Bulletin Topic 5A.In January 2018, the company completed a secondary public offering on the Nasdaq Stock Market of 1,463,414 ordinary shares, at a public offering price of$41.00 per share, in consideration for approximately $64 million net of issuance costs. In addition, the underwriters exercised their option to purchase anadditional 219,512 ordinary shares at the public offering price.Cash flowsThe following table summarizes our statement of cash flows for the years ended December 31, 2017, 2016 and 2015: Year Ended December 31, 2017 2016 2015 (in thousands) Net cash provided by (used in): Operating activities $(9,571) $4,189 $(7,175)Investing activities (36,377) (793) (301)Financing activities 61,585 (9) 21,581 Net cash (used in) provided by operating activitiesThe cash used in operating activities during the aforementioned periods resulted primarily from our net losses incurred during such periods, as adjusted fornon-cash charges and measurements and changes in components of working capital. Adjustments to net losses for non-cash items mainly includeddepreciation and amortization, fair value adjustment of the Preferred A-1 warrants and share-based compensation.Net cash used in operating activities was $9.6 million during the year ended December 31, 2017, compared to $4.2 million provided by operating activitiesduring the year ended December 31, 2016. The increase in cash used in operating activities was attributable primarily to the receipt of the different milestonepayments from Allergan of $7.5 million in 2017 and $17.5 million in 2016 and an increase in expenditures related to the MitoGel Phase 3 clinical trial ofapproximately $3.1 million, as well as an increase in personnel related costs to support our growing business and service provider costs related to becoming apublic company. These increases were offset by the recording of $1.7 million of IPO expenses in 2016.Net cash provided by operating activities was $4.2 million in the year ended December 31, 2016, compared to $7.2 million used in operating activities in theyear ended December 31, 2015. The $11.4 million increase was attributable primarily to the decrease of $10.8 million in the loss for the year which mainlyrelated to the $17.5 million revenue from Allergan, partly offset by an increase of $4.5 million in general and administrative expenses as a result ofstrengthening our senior management team and payments to professional services consultants hired by us in preparation for this offering.Net cash used in investing activitiesThe use of cash in investing activities relates primarily to short term investments in mutual funds, the purchase of property and equipment and changes inrestricted deposits.Net cash used in investing activities was $36.4 million during the year ended December 31, 2017, compared to $0.8 million during the year ended December31, 2016. The increase of $35.6 million is primarily related to the Company’s investment in highly liquid, short term mutual funds.75 Net cash used in investing activities was $793,000 in the year ended December 31, 2016, compared to $301,000 in the year ended December 31, 2015. Theuse of cash in investing activities mainly related to leasehold improvements in the Israel and the U.S. offices.Net cash provided by (used in) financing activitiesNet cash provided by financing activities was $61.6 million during the year ended December 31, 2017, compared to cash used in financing activities of $0.1million during the year ended December 31, 2016. The difference is primarily related to the net proceeds received from our IPO in May 2017.Net cash used in financing activities was $9,000 in the year ended December 31, 2016, compared to $21.6 million provided by financing activities in theyear ended December 31, 2015, the difference of which mainly related to funds raised pursuant to the 2015 and 2014 Share Purchase Agreements.In October 2015, we entered into a share purchase agreement, to which we refer as the 2015 Share Purchase Agreement. In September 2014, we entered into ashare purchase agreement, to which we refer as the 2014 Share Purchase Agreement. During 2015, we raised $18.1 million from the 2015 Share PurchaseAgreement and $3.6 million from the 2014 Share Purchase Agreement.Funding RequirementsIn January 2018, the company completed a secondary public offering on the Nasdaq Stock Market of 1,682,926 ordinary shares, at a public offering price of$41.00 per share, in consideration for approximately $64 million net of underwriting discounts and commissions and issuance costs, including exercise of theunderwriters’ option to purchase an additional 219,512 ordinary shares at the public offering price.We believe that our existing cash, cash equivalents and short-term investments will enable us to fund our operating expenses and capital expenditurerequirements for at least the next 12 months. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resourcessooner than we currently expect.Our present and future funding requirements will depend on many factors, including, among other things: •the progress, timing and completion of clinical trials for MitoGel and VesiGel; •preclinical studies and clinical trials for Vesimune or any of our other product candidates; •the costs related to obtaining regulatory approval for MitoGel, VesiGel and Vesimune and any of our other product candidates, and any delays wemay encounter as a result of regulatory requirements or adverse clinical trial results with respect to any of these product candidates; •selling, marketing and patent-related activities undertaken in connection with the commercialization of MitoGel and VesiGel and any of our otherproduct candidates, and costs involved in the development of an effective sales and marketing organization; •the costs involved in filing and prosecuting patent applications and obtaining, maintaining and enforcing patents or defending against claims orinfringements raised by third parties, and license royalties or other amounts we may be required to pay to obtain rights to third party intellectualproperty rights; •potential new product candidates we identify and attempt to develop; and •revenues we may derive either directly or in the form of royalty payments from future sales of MitoGel, VesiGel, Vesimune, BotuGel and any otherproduct candidates.Furthermore, we expect to continue to incur additional costs associated with operating as a public company. Accordingly, we will need to obtain substantialadditional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we would be forced todelay, reduce or eliminate our research and development programs or future commercialization efforts.Until such time, if ever, as we can generate substantial product revenue, we may finance our cash needs through a combination of equity offerings, debtfinancings, collaborations, strategic alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity orconvertible debt securities, your ownership interest will be diluted, and the terms of any additional securities may include liquidation or other preferencesthat adversely affect your rights as a shareholder. Debt financing, if available, may involve agreements that include covenants limiting or restricting ourability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.76 If we raise funds through additional collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rightsto our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we areunable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our productdevelopment or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop andmarket ourselves.For more information as to the risks associated with our future funding needs, see “Item 3.D – Risk Factors.” We will require substantial additional financingto achieve our goals, and a failure to obtain this capital when needed and on acceptable terms, or at all, could force us to delay, limit, reduce or terminate ourproduct development, commercialization efforts or other operations.”C.Research and development, patents and licenses, etc.For a discussion of our research and development activities, see “Item 4.B—Business Overview” and “Item 5.A—Operating Results.”D.Trend information.For a discussion of trends, see “Item 5.A—Operating Results” and “Item 5.B—Liquidity and Capital Resources.”E.Off-balance sheet arrangements.During the periods presented, we did not have, and we do not currently have, any off-balance sheet arrangements, as defined in the rules and regulations ofthe U.S. Securities and Exchange Commission.F.Tabular disclosure of contractual obligations.Our known contractual obligations as of December 31, 2017 are summarized in the following table. The obligations detailed below do not include grantsreceived from the IIA pursuant to which we will owe royalties or reimbursement upon commercialization of our product candidates. As of December 31, 2017,the maximum royalty amount payable by us under these funding arrangements is $2.1 million, excluding interest.Contractual obligations as of December 31, 2017 are as follows: Payments Due By Period Less Than1 Year 1 To 3Years 3 To 5Years Greater Than5 Years Total (in thousands) Operating lease obligations (1) $1,115 $1,927 $497 $80 $3,620 (1)Operating lease obligations consist of payments pursuant to lease agreements for our Israeli offices and laboratory facility and our New York offices. InNovember 2014, we entered into a lease agreement for our Israeli offices effective from February 1, 2015 for a period of three years, with an option toextend the lease agreement by an additional three years. In April 2016, we signed an addendum to the November 2014 lease agreement in order toincrease the office space rented and extend the rental period. In November 2017, we signed an additional addendum to the November 2014 leaseagreement in order to increase the office space rented. The lease agreement is effective until 2019.In November 2015, Urogen Pharma, Inc. entered into a lease agreement for its previous New York office for a period of seven years, which period commencedon May 1, 2016. In September 2017, Urogen Pharma, Inc. entered into a new lease agreement for its current New York office for a period of approximately 41months, which period commenced in October 2017. The new lease agreement will terminate on February 1, 2021, unless earlier terminated in accordance withits terms.G.Safe harbor.This annual report contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act and asdefined in the Private Securities Litigation Reform Act of 1995.

The 2010 Planalso provides for the grant of awards under Section 3(i) of the Ordinance to our Israeli non-employee service providers and controlling shareholders, who arenot eligible for such special tax treatment.83 The 2010 Plan is administered by our board of directors. Although awards under the 2010 Plan may be granted until 10 years after the effective date of the2010 Plan, as of the consummation of our initial public offering, we stopped granting additional awards under the 2010 Plan.The terms of options granted under the 2010 Plan, including the exercise price, vesting provisions and the duration are determined by our board of directorsand set forth in an award agreement. Except as provided in the applicable award agreement, or in the discretion of the compensation committee, an optionmay be exercised only to the extent that it is then exercisable and, generally, shall expire for employees 90 days following termination of the service of thegrantee, and in the case of retiring directors, not later than nine months following our listing on the Nasdaq Global Market.Restricted share units are awards covering a number of hypothetical units with respect to shares that are granted subject to such vesting and transferrestrictions and conditions of payment as our board of directors may determine in an award agreement.

Further, in such event the optionholders may elect to exchange the options for ordinary shares on a cashless exercise basis.C.Board Practices.Board of DirectorsUnder the Israeli Companies Law, our board of directors is responsible for setting our general policies and supervising the performance of management. Ourboard of directors may exercise all powers and may take all actions that are not specifically granted to our shareholders or to management. Our executiveofficers are responsible for our day-to-day management and have individual responsibilities established by our board of directors. Our Chief ExecutiveOfficer is appointed by, and serves at the discretion of, our board of directors, subject to the terms of the employment agreement that we have entered intowith him. All other executive officers are also appointed by our board of directors and are subject to the terms of any applicable employment agreements thatwe may enter into with them.Under our amended and restated articles of association, our board of directors must consist of at least five directors and not more than nine directors. Ourboard of directors currently consists of eight directors. Other than vacancies to be filled through selection by the remaining members of our board, the IsraeliCompanies Law and our amended and restated articles of association provide that directors are elected annually at the general meeting of our shareholders bya vote of the holders of a majority of the voting power represented present and voting in person, by proxy or by other voting instrument at that meeting. Wehave only one class of directors.Under the Israeli Companies Law, our board of directors is required to employ independent judgment and discretion when voting and is prohibited fromentering into any voting arrangements with respect to actions taken at meetings of the board. Further, the Israeli Companies Law provides that in the event adirector learns about an alleged breach of law or improper conduct of business relating to a company matter, said director must promptly take action tosummon a meeting of the board of directors to address any such breach.In accordance with the exemptions available to foreign private issuers under Nasdaq rules, we do not follow the requirements of the Nasdaq rules with regardto the process of nominating directors. Instead, we follow Israeli law and practice, in accordance with which our board of directors (or a committee thereof) isauthorized to recommend to our shareholders director nominees for election.In addition, our amended and restated articles of association allow our board of directors to appoint directors to fill vacancies on our board of directors,including filling empty board seats up to the maximum number of directors permitted under our articles of association, for a term of office equal to theremaining period of the term of office of each director whose office has been vacated. Vacancies on our board of directors may be filled by a vote of a simplemajority of the directors then in office. A director so appointed will hold office until the next annual general meeting of our shareholders in which the otherdirectors then in office are proposed to be replaced or reappointed.Directors may be removed from office by a resolution at a general meeting of shareholders adopted by a majority of the voting power of our company orunder other circumstances set forth in our amended and restated articles of association.84 Under the Israeli Companies Law, we would be required to include on our board of directors at least two members, each of whom qualifies as an externaldirector, and as to whom special qualifications, voting requirements and other provisions would be applicable. We would also be required to include onesuch external director on each of our board committees.Under regulations promulgated under the Israeli Companies Law, Israeli companies whose shares are traded on stock exchanges such as the Nasdaq StockMarket that do not have a controlling shareholder (as defined therein) and which comply with the requirements of the jurisdiction where the company’sshares are traded with respect to the appointment of independent directors and the composition of an audit committee and compensation committee, mayelect not to follow the Israeli Companies Law requirements with respect to the composition of its audit committee and compensation committee and theappointment of external directors. As we do not have a controlling shareholder, we have elected to comply with the requirements of the Nasdaq Stock Marketwith respect to the composition of our board and such committees, and therefore we are exempt from the Israeli Companies Law requirements with respectthereto, including the appointment of external directors.Leadership Structure of the BoardIn accordance with the Israeli Companies Law and our amended and restated articles of association, our board of directors is required to appoint one of itsmembers to serve as chairman of the board of directors.

In general, the board of directors may overturn a resolutionadopted by a committee it has formed; provided, however, that the board’s decision shall not affect the ability of third parties, who were not aware of suchdecision, to rely on the committee’s resolution prior to the time it is overturned. Only members of the board of directors can be members of a boardcommittee, unless the committee is solely advisory.Audit CommitteeOur audit committee consists of Kathryn Falberg, Pini Orbach and Stuart Holden. Kathryn Falberg serves as chairperson of the audit committee.Israeli Companies Law RequirementsUnder the Israeli Companies Law, we are required to maintain an audit committee.Nasdaq Listing RequirementsUnder the Nasdaq Rules, we are required to maintain an audit committee consisting of at least three independent directors, each of whom is financiallyliterate and one of whom has accounting or related financial management expertise.All members of our audit committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and the Nasdaq StockMarket. Our board of directors has determined that Kathryn E. Falberg is an audit committee financial expert as such term is defined by the SEC rules and hasthe requisite financial experience as defined by the Nasdaq Rules. Each of the members of our audit committee is “independent” as such term is defined inRule 10A-3(b)(1) under the Exchange Act and satisfies the independent director requirements under the Nasdaq Rules.Audit Committee RoleOur audit committee charter sets forth the responsibilities of the audit committee consistent with the rules and regulations of the SEC and the Nasdaq Rules,as well as the requirements for such committee under the Israeli Companies Law, including the following: •oversight of our independent registered public accounting firm and recommending the engagement, compensation or termination of engagementof our independent registered public accounting firm to the board of directors in accordance with Israeli law; •recommending the engagement or termination of the person filling the office of our internal auditor; and •recommending the terms of audit and non-audit services provided by the independent registered public accounting firm for pre-approval by ourboard of directors.85 Our audit committee provides assistance to our board of directors in fulfilling its legal and fiduciary obligations in matters involving our accounting,auditing, financial reporting, internal control and legal compliance functions by pre-approving the services performed by our independent accountants andreviewing their reports regarding our accounting practices and systems of internal control over financial reporting. Our audit committee also oversees theaudit efforts of our independent accountants and takes those actions that it deems necessary to satisfy itself that the auditors are independent of management.Under the Israeli Companies Law, our audit committee is responsible for: (i)determining whether there are deficiencies in the business management practices of our company, including in consultation with our internalauditor or the independent auditor, and making recommendations to the board of directors to improve such practices; (ii)determining whether to approve certain related party transactions (including transactions in which an office holder has a personal interest andwhether such transaction is extraordinary or material under the Israeli Companies Law); (iii)establishing the approval process for certain transactions with a controlling shareholder or in which a controlling shareholder has a personalinterest; (iv)where the board of directors approves the working plan of the internal auditor, examining such working plan before its submission to the board ofdirectors and proposing amendments thereto; (v)examining our internal audit controls and internal auditor’s performance, including whether the internal auditor has sufficient resources and toolsto fulfill his or her responsibilities; (vi)examining the scope of our auditor’s work and compensation and submitting a recommendation with respect thereto to our board of directors orshareholders, depending on which of them is considering the appointment of our auditor; and (vii)establishing procedures for the handling of employees’ complaints as to the management of our business and the protection to be provided to suchemployees.Compensation, Nominating and Corporate Governance Committee and Compensation PolicyWe have a compensation, nominating and corporate governance committee. The members of this committee are Arie Belldegrun, Ran Nussbaum, Fred Cohenand Cynthia Butitta. Cynthia Butitta serves as chairperson of the committee.Israeli Companies Law RequirementsUnder the Israeli Companies Law, the board of directors of a public company must maintain a compensation committee.The duties of the compensation, nominating and corporate governance committee include the recommendation to the company’s board of directors of apolicy regarding the terms of engagement of office holders, to which we refer as a compensation policy. Such policy must be adopted by the company’s boardof directors, after considering the recommendations of the compensation, nominating and corporate governance committee, and will need to be approved bythe company’s shareholders, which we refer to as a Special Majority Approval for Compensation. A Special Majority Approval for Compensation requiresshareholder approval by a majority vote of the shares present and voting at a meeting of shareholders called for such purpose, provided that either: (i) suchmajority includes at least a majority of the shares held by all shareholders who are not controlling shareholders and do not have a personal interest in suchcompensation arrangement, excluding abstentions; or (ii) the total number of shares of non-controlling shareholders and shareholders who do not have apersonal interest in the compensation arrangement and who vote against the arrangement does not exceed 2% of the company’s aggregate voting rights. Wehave adopted a compensation policy, which remains subject to shareholder approval. Even if the company’s shareholders do not approve the compensationpolicy, the board of directors may resolve to approve the compensation policy if and to the extent the board determines, in its judgment following internaldiscussions, that approval of the compensation policy is in the best interests of the company.The compensation policy serves as the basis for decisions concerning the financial terms of employment or engagement of office holders, includingexculpation, insurance, indemnification or any monetary payment or obligation of payment in respect of employment or engagement. The compensationpolicy relates to certain factors, including advancement of the company’s long-term objectives, business plan and policies, and creation of appropriateincentives for office holders. It also considers, among other things, the company’s risk management, size and the nature of its operations. The compensationpolicy furthermore considers the following additional factors: •the education, skills, expertise and accomplishments of the relevant office holder; •the office holder’s roles and responsibilities and prior compensation agreements with him or her; •the relationship between the terms offered and the average compensation of the company’s personnel;86 •the impact of disparities in salary upon work relationships in the company; •the possibility of reducing variable compensation at the discretion of the board of directors; •the possibility of setting a limit on the exercise value of non-cash variable equity-based compensation; and •as to severance compensation, the period of service of the office holder, the terms of his or her compensation during such service period, thecompany’s performance during that period of service, the person’s contribution towards the company’s achievement of its goals and themaximization of its profits, and the circumstances under which the person is leaving the company.The compensation policy also includes the following principles: •the link between variable compensation and long-term performance and measurable criteria; •the relationship between variable and fixed compensation, and the ceiling for the value of variable compensation; •the conditions under which an office holder would be required to repay compensation paid to him or her if it was later shown that the data uponwhich such compensation was based was inaccurate and was restated in the company’s financial statements; •the minimum holding or vesting period for variable, equity-based compensation; and •maximum limits for severance compensation.Compensation, Nominating and Corporate Governance Committee RolesThe compensation, nominating and corporate governance committee is responsible for (i) recommending the compensation policy to our board of directorsfor its approval (and subsequent approval by our shareholders) and (ii) duties related to the compensation policy and to the compensation of our officeholders, including: •recommending whether a compensation policy should continue in effect, if the then-current policy has a term of greater than five years from acompany’s initial public offering, or otherwise three years (approval of either a new compensation policy or the continuation of an existingcompensation policy must in any case occur five years from a company’s initial public offering, or otherwise every three years); •recommending to the board of directors’ periodic updates to the compensation policy; •assessing implementation of the compensation policy; •determining whether to approve the terms of compensation of certain office holders which, according to the Israeli Companies Law, require thecommittee’s approval; and •determining whether the compensation terms of a candidate for the position of the chief executive officer of the company needs to be brought toapproval of the shareholders.Our compensation, nominating and corporate governance charter sets forth the responsibilities of the compensation, nominating and corporate committee,which include: •the responsibilities set forth in the compensation policy; •reviewing and approving the granting of options and other incentive awards to the extent such authority is delegated by our board of directors; and •reviewing, evaluating and making recommendations regarding the compensation and benefits for our non-employee directors.In addition, our compensation, nominating and corporate governance committee is responsible for: •overseeing our corporate governance functions on behalf of the board; •making recommendations to the board regarding corporate governance issues; •identifying and evaluating candidates to serve as our directors consistent with the criteria approved by the board; •reviewing and evaluating the performance of the board; •serving as a focal point for communication between director candidates, non-committee directors and our management; •selecting or recommending to the board for selection candidates to the board; and •making other recommendations to the board regarding affairs relating to our directors.87 Disclosure of Compensation of Executive OfficersFor so long as we qualify as a foreign private issuer, we are not required to comply with the proxy rules applicable to U.S. domestic companies, including therequirement applicable to emerging growth companies to disclose the compensation of our Chief Executive Officer, Chief Financial Officer, Chief MedicalOfficer, President, Israeli Operation and other two most highly compensated executive officers on an individual, rather than on an aggregate, basis.Nevertheless, under regulations promulgated under the Israeli Companies Law, we are required to disclose the annual compensation of our five most highlycompensated office holders (as defined under the Israeli Companies Law) on an individual basis, rather than on an aggregate basis. This disclosure will not beas extensive as that required of a U.S. domestic issuer. We intend to commence providing such disclosure, at the latest, in the notice (which is generally partof the proxy statement) for our 2018 annual general meeting of shareholders, which will be filed under cover of a Report of Foreign Private Issuer on Form 6-K and we may elect to provide such information at an earlier date.Internal AuditorUnder the Israeli Companies Law, the board of directors of an Israeli public company must appoint an internal auditor recommended by the audit committee.An internal auditor may not be: •a person (or a relative of a person) who holds more than 5% of the company’s outstanding shares or voting rights; •a person (or a relative of a person) who has the power to appoint a director or the general manager of the company; •an office holder (including a director) of the company (or a relative thereof); or •a member of the company’s independent accounting firm, or anyone on its behalf.The role of the internal auditor is to examine, among other things, our compliance with applicable law and orderly business procedures, and to report to thechief executive officer, the chairman of the board and the chairman of the audit committee. The internal auditor is entitled to receive notice of auditcommittee meetings and to participate in them. In addition, the internal auditor may request that the chairman of the audit committee convene a meetingwithin a reasonable time to discuss an issue raised by the internal auditor. The internal auditor is responsible for preparing a proposal for an annual orperiodical audit plan and submit such plan to the board of directors or the audit committee for their approval. We intend to appoint an internal auditor incompliance with Israeli law.Approval of Related Party Transactions under Israeli LawFiduciary Duties of Directors and Executive OfficersThe Israeli Companies Law codifies the fiduciary duties that office holders owe to a company. Each person listed in the table under “Executive Officers andDirectors” is an office holder under the Israeli Companies Law.An office holder’s fiduciary duties consist of a duty of care and a duty of loyalty. The duty of care requires an office holder to act with the level of care withwhich a reasonable office holder in the same position would have acted under the same circumstances. The duty of loyalty includes an obligation that anoffice holder act in good faith and in the best interests of the company.The duty of care includes a duty to use reasonable means to obtain: •information on the advisability of a given action brought for his or her approval or performed by virtue of his or her position; and •all other important information pertaining to any such action.The duty of loyalty includes a duty to: •refrain from any conflict of interest between the performance of his or her duties to the company and his or her other duties or personal affairs; •refrain from any activity that is competitive with the company; •refrain from exploiting any business opportunity of the company to receive a personal gain for himself or herself or others; and •disclose to the company any information or documents relating to the company’s affairs which the office holder received as a result of his or herposition as an office holder.88 Disclosure of Personal Interests of an Office Holder and Approval of Certain TransactionsThe Israeli Companies Law requires that an office holder promptly disclose to the board of directors any personal interest that he or she may be aware of andall related material information or documents concerning any existing or proposed transaction with the company. An interested office holder’s disclosuremust be made promptly and in any event no later than the first meeting of the board of directors at which the transaction is considered. A personal interestincludes an interest of any person in an action or transaction of a company, including a personal interest of such person’s relative or of a corporate body inwhich such person or a relative of such person is a 5% or greater shareholder, director or general manager or in which he or she has the right to appoint at leastone director or the general manager, but excluding a personal interest stemming from one’s ownership of shares in the company.A personal interest also includes the personal interest of a person for whom the office holder holds a voting proxy or the personal interest of the office holderwith respect to his or her vote on behalf of a person for whom he or she holds a proxy even if such person has no personal interest in the matter. An officeholder is not, however, required to disclose a personal interest if it derives solely from the personal interest of his or her relative in a transaction that is notconsidered an extraordinary transaction. Under the Israeli Companies Law, an “extraordinary transaction” is defined as any of the following: •a transaction other than in the ordinary course of business; •a transaction that is not on market terms; or •a transaction that may have a material impact on a company’s profitability, assets or liabilities.If it is determined that an office holder has a personal interest in a transaction, which is not an extraordinary transaction, approval by the board of directors isrequired for the transaction, unless the company’s articles of association provide for a different method of approval. Further, so long as an office holder hasdisclosed his or her personal interest in a transaction, the board of directors may approve an action by the office holder that would otherwise be deemed abreach of his or her duty of loyalty. However, a company may not approve a transaction or action that is not in the company’s interest or that is not performedby the office holder in good faith.An extraordinary transaction in which an office holder has a personal interest requires approval first by the company’s audit committee and subsequently bythe board of directors.The compensation of, or an undertaking to indemnify or insure, an office holder who is not a director generally requires approval first by the company’scompensation committee, then by the company’s board of directors. If such compensation arrangement or an undertaking to indemnify or insure isinconsistent with the company’s stated compensation policy, or if the office holder is the chief executive officer (apart from a number of specific exceptions),then such arrangement is further subject to a Special Majority Approval for Compensation. If the shareholders of a company do not approve thecompensation terms of office holders at a meeting of the shareholders, other than directors, the compensation committee and board of directors may overridethe shareholders’ decision, subject to certain conditions. Arrangements regarding the compensation, indemnification or insurance of a director require theapproval of the compensation committee, board of directors and shareholders by simple majority, in that order, and under certain circumstances, a SpecialMajority Approval for Compensation.Generally, a person who has a personal interest in a matter which is considered at a meeting of the board of directors or the audit committee may not bepresent at such a meeting or vote on that matter unless the chairman of the audit committee or board of directors (as applicable) determines that he or sheshould be present in order to present the transaction that is subject to approval. If a majority of the members of the audit committee or the board of directors(as applicable) has a personal interest in the approval of a transaction, then all directors may participate in discussions of the audit committee or the board ofdirectors (as applicable) on such transaction and the voting on approval thereof, but shareholder approval is also required for such transaction.Disclosure of Personal Interests of Controlling Shareholders and Approval of Certain TransactionsPursuant to Israeli law, the disclosure requirements regarding personal interests that apply to directors and executive officers also apply to a controllingshareholder of a public company. In the context of a transaction involving a shareholder of the company, a controlling shareholder also includes ashareholder who holds 25% or more of the voting rights in the company if no other shareholder holds more than 50% of the voting rights in the company. Forthis purpose, the holdings of all shareholders who have a personal interest in the same transaction will be aggregated.The approval of the audit committee, the board of directors and the shareholders of the company, in that order, is required for (i) extraordinary transactionswith a controlling shareholder or in which a controlling shareholder has a personal interest, (ii) the engagement with a controlling shareholder or his or herrelative, directly or indirectly, for the provision of services to the company, (iii) the terms of engagement and compensation of a controlling shareholder orhis or her relative who is not an office holder or (iv)89 the employment of a controlling shareholder or his or her relative by the company, other than as an office holder. In addition, the shareholder approvalrequires one of the following, which we refer to as a Special Majority: •at least a majority of the shares held by all shareholders who do not have a personal interest in the transaction and who are present and voting at themeeting approves the transaction, excluding abstentions; or •the shares voted against the transaction by shareholders who have no personal interest in the transaction and who are present and voting at themeeting do not exceed 2% of the aggregate voting rights in the company.To the extent that any such transaction with a controlling shareholder is for a period extending beyond three years and under certain conditions, five yearsfrom a company’s initial public offering, approval is required at the end of such period unless, with respect to certain transactions, the audit committeedetermines that the duration of the transaction is reasonable given the circumstances related thereto.Arrangements regarding the compensation, indemnification or insurance of a controlling shareholder in his or her capacity as an office holder require theapproval of the compensation committee, board of directors and shareholders by a Special Majority.Pursuant to regulations promulgated under the Israeli Companies Law, certain transactions with a controlling shareholder or his or her relative, or withdirectors or other office holders, that would otherwise require approval of a company’s shareholders may be exempt from shareholder approval under certainconditions.Shareholder DutiesPursuant to the Israeli Companies Law, a shareholder has a duty to act in good faith and in a customary manner toward the company and other shareholdersand to refrain from abusing his or her power in the company, including, among other things, in voting at a general meeting and at shareholder class meetingswith respect to the following matters: •an amendment to the company’s articles of association; •an increase of the company’s authorized share capital; •a merger; or •the approval of related party transactions and acts of office holders that require shareholder approval.A shareholder also has a general duty to refrain from discriminating against other shareholders.In addition, certain shareholders have a duty of fairness toward the company. These shareholders include a controlling shareholder, a shareholder who knowsthat he or she has the power to determine the outcome of a shareholder vote and a shareholder who has the power to appoint or to prevent the appointment ofan office holder of the company or other power towards the company. The Israeli Companies Law does not define the substance of the duty of fairness, exceptto state that the remedies generally available upon a breach of contract will also apply in the event of a breach of the duty to act with fairness.Exculpation, Insurance and Indemnification of Directors and OfficersUnder the Israeli Companies Law, a company may not exculpate an office holder from liability for a breach of the duty of loyalty. An Israeli company mayexculpate an office holder in advance from liability to the company, in whole or in part, for damages caused to the company as a result of a breach of duty ofcare but only if a provision authorizing such exculpation is included in its articles of association. Our amended and restated articles of association includesuch a provision. A company may not exculpate in advance a director from liability arising out of a breach of the duty of care with respect to a distribution.Under the Israeli Companies Law, a company may indemnify an office holder in respect of the following liabilities and expenses incurred for acts performedby him or her as an office holder, either pursuant to an undertaking made in advance of an event or following an event, provided its articles of associationinclude a provision authorizing such indemnification: •financial liability imposed on him or her in favor of another person pursuant to a judgment, including a settlement or arbitrator’s award approvedby a court. However, if an undertaking to indemnify an office holder with respect to such liability is provided in advance, then such an undertakingmust be limited to events which, in the opinion of the board of directors, can be foreseen based on the company’s activities when the undertakingto indemnify is given, and to an amount or according to criteria determined by the board of directors as reasonable under the circumstances, andsuch undertaking shall detail the abovementioned foreseen events and amount or criteria;90 •reasonable litigation expenses, including attorneys’ fees, incurred by the office holder (1) as a result of an investigation or proceeding institutedagainst him or her by an authority authorized to conduct such investigation or proceeding, provided that (i) no indictment was filed against suchoffice holder as a result of such investigation or proceeding, and (ii) no financial liability was imposed upon him or her as a substitute for thecriminal proceeding as a result of such investigation or proceeding or, if such financial liability was imposed, it was imposed with respect to anoffense that does not require proof of criminal intent; and (2) in connection with a monetary sanction; and •reasonable litigation expenses, including attorneys’ fees, incurred by the office holder or imposed by a court in proceedings instituted against himor her by the company, on its behalf, or by a third party, or in connection with criminal proceedings in which the office holder was acquitted, or asa result of a conviction for an offense that does not require proof of criminal intent.Under the Israeli Companies Law, a company may insure an office holder against the following liabilities incurred for acts performed by him or her as anoffice holder, if and to the extent provided in the company’s articles of association: •a breach of the duty of loyalty to the company, provided that the office holder acted in good faith and had a reasonable basis to believe that the actwould not harm the company; •a breach of the duty of care to the company or to a third party, to the extent such a breach arises out of the negligent conduct of the office holder;and •a financial liability imposed on the office holder in favor of a third party.Under the Israeli Companies Law, a company may not indemnify, exculpate or insure an office holder against any of the following: •a breach of the duty of loyalty, except for indemnification and insurance for a breach of the duty of loyalty to the company to the extent that theoffice holder acted in good faith and had a reasonable basis to believe that the act would not harm the company; •a breach of the duty of care committed intentionally or recklessly, excluding a breach arising out of the negligent conduct of the office holder; •an act or omission committed with intent to derive illegal personal benefit; or •a fine, civil fine, monetary sanction or forfeit levied against the office holder.Under the Israeli Companies Law, exculpation, indemnification and insurance of office holders in a public company must be approved by the compensationcommittee and the board of directors and, with respect to certain office holders or under certain circumstances, also by the shareholders. See “Approval ofRelated Party Transactions under Israeli Law—Fiduciary Duties of Directors and Executive Officers.”Our amended and restated articles of association permit us to exculpate, indemnify and insure our office holders to the fullest extent permitted or to bepermitted by the Israeli Companies Law.We maintain directors and officers liability insurance for the benefit of our office holders to the fullest extent permitted by the Israeli Companies Law. Inaddition, we have entered into agreements with each of our directors and executive officers exculpating them from liability to us for damages caused to us asa result of a breach of duty of care and undertaking to indemnify them, in each case, to the fullest extent permitted by our amended and restated articles ofassociation and Israeli law. In the opinion of the SEC, however, indemnification of directors and office holders for liabilities arising under the Securities Actis against public policy and therefore unenforceable.D.Employees.

This section also contains a discussion of material Israeli tax consequencesconcerning the ownership and disposition of our ordinary shares. This summary does not discuss certain tax benefits, including under the Law forEncouragement of Capital Investments, 5719-1959, to which we may become eligible in the future if we establish a manufacturing facility for our products inIsrael. This summary also does not discuss all the aspects of Israeli tax law that may be relevant to a particular investor in light of his or her personalinvestment circumstances or to some types of investors subject to special treatment under Israeli law. Examples of such investors include residents of Israel ortraders in securities who are subject to special tax regimes not covered in this discussion. Because parts of this discussion are based on new tax legislationthat has not yet been subject to judicial or administrative interpretation, the appropriate tax authorities or the courts may not accept the views expressed inthis discussion. The discussion below is subject to change, including due to amendments under Israeli law or changes to the applicable judicial oradministrative interpretations of Israeli law, which change could affect the tax consequences described below.General Corporate Tax Structure in IsraelAs of 2018, Israeli companies are generally subject to corporate tax at the rate of 23% of a company’s taxable income (reduced from 24% in 2017). Inaddition, capital gains realized by Israeli companies are subject to tax at the regular corporate tax rate.Taxation of our ShareholdersCapital gains taxes applicable to non-Israeli resident shareholders. As of 2018, capital gain is generally subject to tax at the corporate tax rate of 23%(reduced from 24% in 2017) if generated by a company, or at the rate of 25% if generated by an individual, or 30% in the case of sale of shares by asubstantial shareholder at the time of sale or at any time during the preceding 12-month period. A person is considered to be a substantial shareholder if itholds, directly or indirectly, alone or together with another affiliated party, 10% or more of a company’s means of control, which include, among other things,voting rights, the right to receive profits of the company, the right to receive proceeds upon liquidation and the right to appoint a director.Notwithstanding the foregoing, a non-Israeli resident who derives capital gains from the sale of our shares that were purchased after the shares were listed fortrading on the Nasdaq is exempt from Israeli tax on such capital gains so long as they were not attributable to a permanent establishment that the non-residentmaintains in Israel. In the case of a shareholder that is a corporation, in order for it to qualify as a non-Israeli resident for these purposes, it must beincorporated in, as well as managed and controlled from, a jurisdiction other than the98 State of Israel, and persons who are Israeli residents may not either: (i) have a controlling interest (directly or indirectly, alone or together with another, ortogether with another Israeli resident) exceeding 25% in one or more of the means of control in such corporation or (ii) be the beneficiaries of, or entitled to,25% or more of the revenues or profits of such corporation, whether directly or indirectly. Such exemption is not applicable to a person whose gains fromselling or otherwise disposing of the shares are deemed to be business income.Additionally, a sale of shares by a non-Israeli resident may be exempt from Israeli capital gains tax under the provisions of an applicable tax treaty.Shareholders may be required to demonstrate that they are exempt from tax on their capital gains in order to avoid withholding at source at the time of sale. Intransactions involving a sale of all of the shares of an Israeli resident company, such as a merger or other transaction, the Israel Tax Authority may, amongother things, require from shareholders who are not liable for Israeli tax the execution of a declaration in the form specified by that authority or a specificexemption from the Israeli Tax Authority to confirm their status as non-Israeli residents may be required to be presented, and, in the absence of suchdeclaration or exemption, may require the purchaser of the shares to withhold taxes.In addition, with respect to mergers involving an exchange of shares, Israeli tax law allows for tax deferral in certain circumstances but makes the deferralcontingent on the fulfillment of a number of conditions, including, in some cases, a holding period of two years from the date of the transaction during whichsales and dispositions of shares of the participating companies are subject to certain restrictions. Moreover, with respect to certain share swap transactions inwhich the sellers receive shares in the acquiring entity that are publicly traded on a stock exchange, the tax deferral is limited in time, and when such timeexpires, the tax becomes payable even if no disposition of such shares has occurred.Taxation of non-Israeli shareholders on receipt of dividends. Non-Israeli residents are generally subject to Israeli withholding tax on the receipt of dividendspaid on our ordinary shares at the rate of 25%, unless relief is provided in a treaty between Israel and the shareholder’s country of residence (subject to thereceipt of a valid certificate from the Israel Tax Authority, allowing for such reduced withholding tax rate). With respect to a person who is considered asubstantial shareholder at the time of receiving the dividend or at any time during the preceding 12 months, subject to the terms of an applicable tax treaty,the applicable withholding tax rate is 30%.Under the Convention between the Government of the United States of America and the Government of the State of Israel with respect to Taxes on Income, orthe U.S.-Israel Tax Treaty, the maximum rate of tax withheld at source in Israel on dividends paid to a holder of our ordinary shares who is a U.S. resident (forthe purposes of the U.S.-Israel Tax Treaty) is 25%. However, with regard to dividends paid to a U.S. resident corporation which held 10% or more of ouroutstanding voting rights throughout the taxable year in which the dividend was distributed and which maintained its shareholdings at or above suchthreshold during the entire previous taxable year, the maximum rate of withholding tax is generally 12.5%, provided that no more than 25% of our grossincome for such preceding year consists of certain types of dividends and interest.U.S. residents who are subject to Israeli withholding tax on a dividend may be entitled to a credit or deduction for U.S. federal income tax purposes in theamount of the taxes withheld, subject to detailed limitations under U.S. laws applicable to foreign tax credits.Excess Tax. Individuals who are subject to tax in Israel, whether an Israeli resident or a non-Israeli resident, are also subject to an additional tax on annualincome exceeding NIS 640,000 in 2017 and thereafter (linked to the Israeli consumer price index) at a rate of 3%, including, but not limited to, dividends,interest and capital gain, subject to the provisions of an applicable tax treaty.Material U.S. Federal Income Tax Consequences to U.S. HoldersThe following discussion describes the material U.S. federal income tax consequences to U.S. Holders (as defined below) under present law of an investmentin our ordinary shares. The effects of any applicable state or local laws, or other U.S. federal tax laws such as estate and gift tax laws are not discussed. Thissummary applies only to investors who hold the ordinary shares as capital assets (generally, property held for investment) and who have the U.S. dollar astheir functional currency. This discussion is based on the Internal Revenue Code of 1986, as amended, or the Code, U.S. Treasury regulations promulgatedthereunder, judicial decisions, published rulings and administrative pronouncements of the U.S. Internal Revenue Service, or the IRS, and the U.S.-Israel TaxTreaty, all as in effect as of the date of annual report. All of the foregoing authorities are subject to change, which change could apply retroactively and couldaffect the tax consequences described below.The following discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances or to holders subject toparticular rules, including: •U.S. expatriates and certain former citizens or long-term residents of the United States; •persons subject to the alternative minimum tax;99 •persons holding our ordinary shares as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or otherintegrated investment for U.S. federal income tax purposes; •banks, insurance companies, and other financial institutions; •real estate investment trusts and regulated investment companies; •brokers, dealers, and traders in securities, commodities or currencies; •partnerships, S corporations, and other entities or arrangements treated as partnerships for U.S. federal income tax purposes; •tax-exempt organizations and governmental organizations; •persons who acquired our ordinary shares pursuant to the exercise of any employee share option or otherwise as compensation; •persons that own, directly, indirectly or constructively 10% or more of our stock; •persons that hold their shares through a permanent establishment or fixed base outside the United States; and •persons deemed to sell our ordinary shares under the constructive sale provisions of the Code.U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL TAX RULES TOTHEIR PARTICULAR CIRCUMSTANCES AS WELL AS THE U.S. STATE AND LOCAL AND NON-U.S. TAX CONSEQUENCES TO THEM OF THEPURCHASE, OWNERSHIP AND DISPOSITION OF THE ORDINARY SHARES.For purposes of this discussion, a “U.S. Holder” is a beneficial owner of our ordinary shares that, for U.S. federal income tax purposes, is or is treated as any ofthe following: •an individual who is a citizen or resident of the United States; •a corporation, or entity treated as a corporation for U.S. federal income tax purposes, created or organized under the laws of the United States, anystate thereof, or the District of Columbia; •an estate, the income of which is subject to U.S. federal income tax regardless of its source; or •a trust that (1) is subject to the supervision of a U.S. court and the control of one or more “United States persons” (within the meaning of Section7701(a)(30) of the Code), or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.If you are a partner in a partnership (or other entity taxable as a partnership for U.S. federal income tax purposes) that holds our ordinary shares, your taxtreatment generally will depend on your status and the activities of the partnership. Partnerships holding our ordinary shares and the partners in suchpartnerships should consult their tax advisors regarding the U.S. federal income tax consequences applicable to them.As indicated below, this entire discussion is subject to the discussion of the U.S. federal income tax rules applicable to a “passive foreign investmentcompany,” or a PFIC.Passive Foreign Investment Company ConsiderationsIf we are classified as a PFIC in any taxable year, a U.S. Holder will be subject to special rules generally intended to reduce or eliminate any benefits from thedeferral of U.S. federal income tax that a U.S. Holder could derive from investing in a non-U.S. company that does not distribute all of its earnings on acurrent basis.We must determine our PFIC status annually based on tests (described below) which are factual in nature, and our status will depend on our income, assetsand activities each year. We do not believe that we were classified as a PFIC for the taxable year ended December 31, 2017. However, based upon theexpected nature and composition of our income and assets, we presently anticipate that we will be classified as a PFIC for the taxable year ending December31, 2018. We cannot provide any assurances regarding our PFIC status for the current or future taxable years, and our U.S. tax counsel has not provided anyopinion regarding our PFIC status.A non-U.S. corporation is classified as a PFIC for U.S. federal income tax purposes in any taxable year in which, after applying certain look-through rules withrespect to the income and assets of subsidiaries, either (i) at least 75% of its gross income is “passive income” or (ii) at least 50% of the average quarterlyvalue of its total gross assets (which, assuming we are not a CFC for the year being tested, would be measured by fair market value of the assets, and for whichpurpose the total value of our assets may be100 determined in part by the market value of our ordinary shares, which is subject to change) is attributable to assets that produce “passive income” or are heldfor the production of passive income.Passive income for this purpose generally includes dividends, interest, royalties, rents, gains from commodities and securities transactions, the excess of gainsover losses from the disposition of assets which produce passive income, and generally includes amounts derived by reason of the temporary investment offunds raised in offerings of our ordinary shares. However, rents and royalties received from unrelated parties in connection with the active conduct of a tradeor business are not considered passive income for purposes of the PFIC test. If a non-U.S. corporation owns directly or indirectly at least 25% by value of thestock of another corporation, the non-U.S. corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the othercorporation and as receiving directly its proportionate share of the other corporation’s income. If we are classified as a PFIC in any year with respect to whicha U.S. Holder owns our ordinary shares, we will continue to be treated as a PFIC with respect to such U.S. Holder in all succeeding years during which the U.S.Holder owns our ordinary shares, regardless of whether we continue to meet the tests described above unless the holder makes a so-called “purging election”with respect to our ordinary shares.U.S. Holders should consult with their tax advisors regarding the availability and consequences of any PFIC purging elections.If we are a PFIC, and you are a U.S. Holder, then unless you make one of the elections described below, a special tax regime will apply to both (a) any “excessdistribution” by us to you (generally, your ratable portion of aggregate distributions in any year which are greater than 125% of the average annualdistribution received by you in the shorter of the three preceding years or your holding period for our ordinary shares) and (b) any gain realized on the sale orother disposition of the ordinary shares. Under this regime, any excess distribution and realized gain will be treated as ordinary income and will be subject totax as if (a) the excess distribution or gain had been realized ratably over your holding period, (b) the amount deemed realized in each year had been subjectto tax in each year of that holding period at the highest marginal rate for such year (other than income allocated to the current period or any taxable periodbefore we became a PFIC, which would be subject to tax at the U.S. Holder’s regular ordinary income rate for the current year and would not be subject to theinterest charge discussed below), and (c) the interest charge generally applicable to underpayments of tax had been imposed on the taxes deemed to havebeen payable in those years. In addition, dividend distributions made to you will not qualify for the lower rates of taxation applicable to long-term capitalgains discussed under “Taxation of Dividends and Other Distributions on our Ordinary Shares.”Certain elections exist that may alleviate some of the adverse consequences of PFIC status and would result in an alternative treatment (such as mark-to-market treatment) of our ordinary shares. If a U.S. Holder makes the mark-to-market election, then in lieu of being subject to the tax and interest change rulesdisclosed above, the U.S. Holder generally will recognize as ordinary income any excess of the fair market value of the ordinary shares at the end of eachtaxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax basis of the ordinary shares overtheir fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a result of the mark-to-marketelection). If a U.S. Holder makes the election, the U.S. Holder’s tax basis in the ordinary shares will be adjusted to reflect these income or loss amounts. Anygain recognized on the sale or other disposition of ordinary shares in a year when we are a PFIC will be treated as ordinary income and any loss will be treatedas an ordinary loss (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). The mark-to-marketelection is available only if we are a PFIC and our ordinary shares are “regularly traded” on a “qualified exchange.” Our ordinary shares will be treated as“regularly traded” in any calendar year in which more than a de minimis quantity of the ordinary shares are traded on a qualified exchange on at least 15 daysduring each calendar quarter (subject to the rule that trades that have as one of their principle purposes the meeting of the trading requirement aredisregarded). The Nasdaq Global Market is a qualified exchange for this purpose and, consequently, if the ordinary shares are regularly traded, the mark-to-market election will be available to a U.S. Holder.We do not currently intend to provide the information necessary for U.S. Holders to make QEF elections. U.S. Holders should consult their tax advisors todetermine whether any of these elections would be available and if so, what the consequences of the alternative treatments would be in their particularcircumstances.If we are determined to be a PFIC, the general tax treatment for U.S. Holders described in this section will apply to indirect distributions and gains deemed tobe realized by U.S. Holders in respect of any of our subsidiaries that also may be determined to be PFICs. A mark-to-market election cannot be made withrespect to the stock of any of our subsidiaries.Each U.S. Holder that is an investor of a PFIC is generally required to file an annual information return on IRS Form 8621 (Information Return by aShareholder of a Passive Foreign Investment Company or Qualified Electing Fund) containing such information as the U.S. Treasury Department may require.The failure to file IRS Form 8621 could result in the imposition of penalties and the extension of the statute of limitations with respect to U.S. federal incometax. U.S. Holders should consult their tax advisors regarding whether we are a PFIC and the potential application of the PFIC rules.101 Taxation of Dividends and Other Distributions on our Ordinary SharesSubject to the discussion under “—Passive Foreign Investment Company Considerations,” above, the gross amount of any distribution to you with respect toour ordinary shares will be included in your gross income as dividend income when actually or constructively received to the extent that the distribution ispaid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). To the extent the amount of thedistribution exceeds our current and accumulated earnings and profits, it will be treated first as a return of your tax basis in our ordinary shares, and to theextent the amount of the distribution exceeds your tax basis, the excess will be taxed as capital gain. We do not intend to calculate our earnings and profitsunder U.S. federal income tax principles. Therefore, a U.S. Holder should expect that the entire amount of any distribution will generally be reported asdividend income. Any dividends will not be eligible for the dividends-received deduction allowed to corporations in respect of dividends received fromother U.S. corporations.If we are not a PFIC for a given year in which a dividend is paid and the taxable year preceding the dividend, non-corporate U.S. Holders may qualify for thepreferential rates of taxation with respect to dividends on ordinary shares applicable to long-term capital gains (i.e., gains from the sale of capital assets heldfor more than one year) applicable to qualified dividend income (as discussed below). We believe that we qualify as a resident of Israel for purposes of, andare eligible for the benefits of, the U.S.-Israel Tax Treaty, although there can be no assurance in this regard. Further, the IRS has determined that the U.S.-IsraelTax Treaty is satisfactory for purposes of the qualified dividend rules and that it includes an exchange-of-information program. Therefore, subject to thediscussion under “—Passive Foreign Investment Company Considerations” above, if the U.S.-Israel Tax Treaty is applicable, such dividends will generallybe “qualified dividend income” in the hands of individual U.S. Holders, provided that certain conditions are met, including holding period and the absenceof certain risk reduction transaction requirements. The dividends will not be eligible for the dividends received deduction generally allowed to corporate U.S.Holders. As discussed in “Taxation—Israeli Tax Considerations and Government Programs,” payments of dividends by us may be subject to Israeliwithholding tax. For U.S. federal income tax purposes, U.S. Holders will be treated as having received the amount of Israeli taxes withheld by us, and as thenhaving paid over the withheld taxes to the Israeli taxing authorities. As a result of this rule, the amount of dividend income included in gross income for U.S.federal income tax purposes by a U.S. Holder with respect to a payment of dividends may be greater than the amount of cash actually received (or receivable)by the U.S. Holder from us with respect to the payment. Dividends will generally constitute foreign source income for foreign tax credit limitation purposes.Any tax withheld with respect to distributions on our ordinary shares at the rate applicable to a U.S. Holder may, subject to a number of complex limitations,be claimed as a foreign tax credit against such U.S. Holder’s U.S. federal income tax liability or may be claimed as a deduction for U.S. federal income taxpurposes. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividendsdistributed by us with respect to our ordinary shares generally will constitute “passive category income” or “general category income.” The rules with respectto the foreign tax credit are complex and involve the application of rules that depend upon a U.S. Holder’s particular circumstances. You are urged to consultyour tax advisor regarding the availability of the foreign tax credit under your particular circumstances.Taxation of Disposition of the Ordinary SharesSubject to the discussion above under “—Passive Foreign Investment Company Considerations,” you will recognize gain or loss on any sale, exchange orother taxable disposition of an ordinary share equal to the difference between the amount realized on the disposition of the ordinary share and your adjustedtax basis in the ordinary share. The tax basis in an ordinary share generally will be the cost of such ordinary share. Any such gain or loss will be capital gainor loss and will be long-term capital gain or loss if you have held the ordinary share for more than one year at the time of sale, exchange or other taxabledisposition. Otherwise, such gain or loss will be short-term capital gain or loss. Long-term capital gains recognized by certain non-corporate U.S. Holders,including individuals, generally will be taxable at a reduced rate. The deductibility of capital losses is subject to limitations. Any such gain or loss yourecognize generally will be treated as U.S. source income or loss for foreign tax credit limitation purposes.Additional Medicare TaxCertain U.S. Holders that are individuals, estates or trusts are subject to a 3.8% tax on all or a portion of their “net investment income,” which may include allor a portion of their dividend income and net gains from the disposition of ordinary shares. Each U.S. Holder that is an individual, estate or trust is urged toconsult its tax advisors regarding the applicability of the Medicare tax to its income and gains in respect of its investment in our ordinary shares.Information Reporting and Backup WithholdingU.S. backup withholding tax and information reporting requirements may apply to certain payments to certain holders of our ordinary shares. Informationreporting will generally apply to payments of dividends on, and to proceeds from the sale or redemption of, our ordinary shares made within the UnitedStates, or by a U.S. payer or U.S. middleman, to a holder of our shares, other than an exempt102 recipient (including a payee that is not a U.S. person that provides an appropriate certification and certain other persons). Certain U.S. Holders are exemptfrom backup withholding, including corporations and certain tax-exempt organizations. A U.S. Holder will be subject to backup withholding if such holder isnot otherwise exempt and such holder: •fails to furnish the holder’s taxpayer identification number, which for an individual is ordinarily his or her social security number; •furnishes an incorrect taxpayer identification number; •is notified by the IRS that the holder previously failed to properly report payments of interest or dividends; or •fails to certify under penalties of perjury that the holder has furnished a correct taxpayer identification number and that the IRS has not notified theholder that the holder is subject to backup withholding.Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against theU.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS. U.S. Holders should consult their tax advisorsregarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.Additional Reporting RequirementsCertain U.S. Holders who are individuals (and under proposed regulations, certain entities) are required to report information relating to an interest in ourordinary shares, subject to certain exceptions (including an exception for ordinary shares held in accounts maintained by financial institutions) by filing IRSForm 8938 (Statement of Specified Foreign Financial Assets) with their federal income tax return. U.S. Holders should consult their tax advisors regarding thepossible implications of these tax return disclosure obligations.F.Dividends and paying agents.Not applicable.G.Statement by experts.Not applicable. H.Documents on display.We are subject to certain of the information reporting requirements of the Exchange Act, or the Exchange Act. As a foreign private issuer, we are exempt fromthe rules and regulations under the Exchange Act prescribing the furnishing and content of proxy statements, and our officers, directors and principalshareholders are exempt from the reporting and “short-swing” profit recovery provisions contained in Section 16 of the Exchange Act, with respect to theirpurchase and sale of our shares. In addition, we are not required to file reports and financial statements with the SEC as frequently or as promptly as U.S.companies whose securities are registered under the Exchange Act. However, we are required to file with the SEC, within four months after the end of eachfiscal year, an annual report on Form 20-F containing financial statements audited by an independent accounting firm. We publish unaudited interimfinancial information after the end of each quarter. We furnish this quarterly financial information to the SEC under cover of a Form 6-K.You may read and copy any document we file with the SEC at its public reference facilities at 100 F Street, NE, Washington, D.C. 20549. You may alsoobtain copies of the documents at prescribed rates by writing to the Public Reference Section of the SEC at 100 F Street, NE, Washington, D.C. 20549. TheSEC also maintains a website that contains reports, proxy and information statements and other information regarding registrants that file electronically withthe SEC.

Quantitative and Qualitative Disclosures About Market Risk.Market risk is the risk of loss related to changes in market prices, including interest rates and foreign exchange rates, of financial instruments that mayadversely impact our financial position, results of operations or cash flows.103 Foreign currency exchange riskThe U.S. dollar is our functional and reporting currency. However, a significant portion of our operating expenses are incurred in NIS. As a result, we areexposed to the risk that the NIS may appreciate relative to the dollar, or, if the NIS instead devalues relative to the dollar, that the inflation rate in Israel mayexceed such rate of devaluation of the NIS, or that the timing of such devaluation may lag behind inflation in Israel. In any such event, the dollar cost of ouroperations in Israel would increase and our dollar-denominated results of operations would be adversely affected. We cannot predict any future trends in therate of inflation in Israel or the rate of devaluation, if any, of the NIS against the dollar. For example, although the dollar appreciated against the NIS in 2015by 0.3%, the level of devaluation of the dollar against the NIS in 2016 was 1.5%. If the dollar cost of our operations in Israel increases, our dollar-measuredresults of operations will be adversely affected. Our operations also could be adversely affected if we are unable to effectively hedge against currencyfluctuations in the future.We do not currently engage in currency hedging activities in order to reduce this currency exposure, but we may begin to do so in the future. Instruments thatmay be used to hedge future risks may include foreign currency forward and swap contracts. These instruments may be used to selectively manage risks, butthere can be no assurance that we will be fully protected against material foreign currency fluctuations.Liquidity riskWe monitor forecasts of our liquidity reserve (comprising cash and cash equivalents and deposits). We generally carry this out based on our expected cashflows in accordance with practice and limits set by our management. We are in the research and development stage and we are therefore exposed to liquidityrisk. However, we believe that our existing cash, cash equivalents and short-term investments will enable us to fund our operating expenses and capitalexpenditure requirements for at least the next 12 months.Inflation riskWe do not believe that the rate of inflation in Israel has had a material impact on our business to date, however, our costs in Israel will increase if inflation inIsrael exceeds the devaluation of the shekel against the U.S. dollar or if the timing of such devaluation lags behind inflation in Israel.Item 12.

Corporate Governance.Home Country Practice ExemptionsCompanies incorporated under the laws of the State of Israel, whose shares are publicly traded, including companies with shares listed on the Nasdaq GlobalMarket, are considered public companies under Israeli law and are required to comply with various corporate governance requirements under Israeli lawrelating to such matters as the composition and responsibilities of the audit committee and the compensation committee (subject to certain exceptions thatwe intend to continue to utilize), and a requirement to have an internal auditor. This is the case even if our shares are not listed on the Tel Aviv StockExchange, or TASE, which our shares are not expected to be. These requirements are in addition to the corporate governance requirements imposed by theNasdaq Rules and other applicable provisions of U.S. securities laws to which we are subject (as a foreign private issuer). Under the Nasdaq Rules, a foreignprivate issuer may generally follow its home country rules of corporate governance in lieu of the comparable requirements of the Nasdaq Rules, except forcertain matters including the composition and responsibilities of the audit committee and the independence of its members within the meaning of the rulesand regulations of the SEC.We have elected to rely on this “home country practice exemption” with respect to the following Nasdaq requirements: •Quorum. As permitted under the Israeli Companies Law and pursuant to our articles of association, the quorum required for an ordinary meeting ofshareholders consists of at least two shareholders present in person, by proxy or by other voting instrument in accordance with the IsraeliCompanies Law, who hold at least 331/3% of the voting power of our shares (and in an adjourned meeting, with some exceptions, at least twoshareholders), instead of 331/3% of the issued share capital required under the Nasdaq Rules. •Nomination of Directors. With the exception of directors elected by our board of directors due to a vacancy, our directors are elected at an annualgeneral meeting of our shareholders and hold office until the next annual general meeting following his or her election. The nominations fordirectors, which are presented to our shareholders by our board of directors, are generally made by the board of directors itself or a duly authorizedcommittee thereof, in accordance with the provisions of our articles of association and the Israeli Companies Law. •Proxy Statements. We are not required to and, in reliance on home country practice, we do not comply with certain Nasdaq Rules regarding theprovision of proxy statements for general meetings of shareholders. Israeli corporate law does not have a regulatory regime for the solicitation ofproxies. We intend to provide notice convening an annual general meeting, including an agenda and other relevant documents. •Shareholder Approval. We are not required to and, in reliance on home country practice, we do not comply with certain Nasdaq Rules regardingshareholder approval for certain issuances of securities under Nasdaq Rule 5635. In accordance with the provisions of our articles of associationand the Israeli Companies Law, our board of directors is authorized to issue securities, including shares, warrants and convertible notes. •Executive Sessions. We are not required to and, in reliance on home country practice, we do not comply with certain Nasdaq Rules regardingregularly scheduled meetings at which only independent directors are present. In accordance with the provisions of our articles and the IsraeliCompanies Law, such regularly scheduled meetings at which only independent directors are present are not required.Other than as stated above, we currently take all actions necessary to maintain compliance as a foreign private issuer under the applicable corporategovernance requirements of the Sarbanes-Oxley Act, the rules adopted by the SEC and the Nasdaq Rules. We may in the future elect to use the home countrypractice exemption with respect to some or all of the other Nasdaq Rules.Item 16H. Mine Safety DisclosureNot applicable.107 PART IIIItem 17.

Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management and board of directors. Our responsibility is to expressan opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the PublicCompany Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordancewith the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require thatwe plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement,whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to erroror fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding theamounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used andsignificant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe thatour audits provide a reasonable basis for our opinion.

F-6 UROGEN PHARMA LTD.NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(U.S. dollars in thousands, except share and per share data)NOTE 1—NATURE OF OPERATIONSUroGen Pharma Ltd. is an Israeli company incorporated in April 2004 (“UPL”).UroGen Pharma Inc., a subsidiary of UPL, was incorporated in Delaware in October 2015 and began operating in February 2016 (“UPI”).UPL and UPI (together the “Company”) is a clinical stage biopharmaceutical company focused on developing novel therapies designed to change thestandard of care for urological pathologies.In August 2015 the Company entered into an agreement with Allergen Pharmaceuticals International Limited (“Allergen”), a wholly owned subsidiary ofAllergan plc, pursuant to which the Company undertook to supply its gel product and supporting services to Allergan for consideration of $750, to allowAllergan to conduct certain scientific investigations aimed at testing utility of the Company’s gel product for the delivery of a certain proprietary product ofAllergan. Further, the Company granted Allergan a time limited option to negotiate an exclusive, worldwide right to research, develop, make and have made,use, sell, offer to sell and import the Company’s product in combination with Allergan’s product. Pursuant to the terms of the agreement from 2015, on October 7, 2016, the Company entered into an exclusive license agreement with Allergan to licenseworldwide rights to some of its products indicated for use with neurotoxins. As stipulated in the agreement, Allergan paid a non-refundable upfront fee of$17.5 million in accordance with the terms of the license agreement. Allergan shall pay the Company additional milestone payments of up to $207.5 millionand tiered royalty payments as a percentage of net sales of the licensed product all as stated in the agreement. As described in Note 8a, in April 2017, the Company’s board of directors and shareholders approved an aggregate 3.2-for-1 share split of the Company’sordinary, Preferred A and Preferred A-1 shares. All of the share and per share amounts reflected in these financial statements and the notes thereto have beenadjusted, on a retroactive basis, to reflect this share split. In May 2017, the Company raised $60.8 million, net of issuance costs and underwriting discounts, in an Initial Public Offering ("IPO") on the Nasdaq StockMarket (“Nasdaq”) (see Note 8a). During July 2017, the Company earned a milestone payment of $7.5 million resulting from Allergan’s submission of an Investigational New Drug (“IND”)application for the Company’s RTGel in combination with Allergan’s BOTOX for the treatment of overactive bladder to the U.S. Food and DrugAdministration (“FDA”). The Company received the milestone payment in August 2017. In January 2018, the Company completed a secondary public offering on the Nasdaq Stock Market in consideration for approximately $64 million net ofissuance costs. Also, see Note 12.As of the date of issuance of the consolidated financial statements, the Company has the ability to fund its planned operations for at least the next 12 months.However, the Company’s product candidates may never achieve commercialization and it will continue to incur losses for the foreseeable future. Therefore,in order to fund the Company’s research and development expenses, general and administrative expenses and capital expenditures until such time that theCompany can generate substantial revenues, the Company may need to raise additional funds. NOTE 2—SIGNIFICANT ACCOUNTING POLICIESa. Basis of presentationThe Company’s financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S.GAAP”).F-7UROGEN PHARMA LTD.NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(U.S. dollars in thousands, except share and per share data) b. Principles of consolidationThe consolidated financial statements include the financial statements of UPL and its wholly owned subsidiary, UPI. Intercompany transactions and balanceshave been eliminated in consolidation.c. Use of estimates in the preparation of financial statementsThe preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reportedamounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenuesand expenses during the reporting period. Actual results may differ from those estimates. As applicable to these consolidated financial statements, the mostsignificant estimates and assumptions relate to the fair value of share-based compensation, the fair value of the warrants for preferred shares and timing ofrevenue recognition.d. Functional currencyThe U.S. dollar (“Dollar”) is the currency of the primary economic environment in which the operations of the Company and subsidiary are conducted.Therefore, the functional currency of the Company is the Dollar.Accordingly, transactions in currencies other than the Dollar are measured and recorded in the functional currency using the exchange rate in effect at thedate of the transaction. At the balance sheet date, monetary assets and liabilities that are denominated in currencies other than the Dollar are measured usingthe official exchange rate at the balance sheet date. The effects of foreign currency re-measurements are recorded in the consolidated statements of operationsas “financial income (expenses).”e. Cash and cash equivalentsThe Company considers as cash equivalents all short-term, highly liquid investments, which include short-term bank deposits with original maturities ofthree months or less from the date of purchase that are not restricted as to withdrawal or use and are readily convertible to known amounts of cash. f. Short-term investmentsThe Company invests in short-term investments that consist of mutual and bond funds. While these investments are considered highly liquid and availableto fund current operations, there is more than an insignificant risk of change in value due to interest rate, quoted price, or penalty on withdrawal and aretherefore classified as short-term investments.We classify our short-term investments as available-for-sale in accordance with FASB ASC Topic 320, “Investments — Debt and Equity Securities”.Available-for-sale securities are carried at fair value with unrealized gains and losses reported in other comprehensive income/loss within stockholders’equity. There was no change in value for the period. Short-term investments are valued using models or other valuation methodologies that use Level 2 inputs. These models are primarily industry-standardmodels that consider various assumptions, including time value, yield curve, volatility factors, default rates, current market and contractual prices for theunderlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, canbe derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. g. Property and equipment1)Property and equipment are stated at cost, net of accumulated depreciation.2)The Company’s property and equipment are depreciated using the straight-line method on the basis of their estimated useful lives.F-8UROGEN PHARMA LTD.NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(U.S. dollars in thousands, except share and per share data) Annual rates of depreciation are as follows: %Computers and software 33Laboratory equipment 15-30Furniture 6-15Manufacturing equipment 50 Leasehold improvements are amortized using the straight-line method over the shorter of the expected lease term and the estimated useful life of theimprovements.h. Impairment of long-lived assetsThe Company tests long-lived assets, comprised solely of property and equipment, for impairment whenever events or circumstances present an indication ofimpairment. If the sum of expected future undiscounted cash flows of the assets is less than the carrying amount of such assets, an impairment loss would berecognized. The assets would be written down to their estimated fair values, calculated based on the present value of expected future discounted cash flows orsome other fair value measure.As of December 31, 2017 and 2016, the Company did not recognize an impairment loss for its long-lived assets. i. Financial instrumentsWhen the Company issues preferred shares, it considers the provisions of ASC 480 in order to determine whether the preferred share should be classified as aliability. If the instrument is not within the scope of ASC 480, the Company further analyzes the instrument’s characteristics in order to determine whether itshould be classified within temporary equity (mezzanine) or within permanent equity in accordance with the provisions of ASC 480-10-S99.When the Company issues other freestanding instruments, the Company first analyzes the provisions of ASC 480 in order to determine whether theinstrument should be classified as a liability, with subsequent changes in fair value recognized in earnings in each period.If the instrument is not within the scope of ASC 480, the Company further analyzes the provisions of ASC 815-40 in order to determine whether theinstrument should be classified within equity or rather classified as an asset or liability, with subsequent changes in fair value recognized in earnings in eachperiod. See note 7 and note 8.j. Share-based compensationThe Company accounts for employees’ and directors’ share-based payment awards classified as equity awards using the grant-date fair value method. The fairvalue of share-based payment transactions is recognized as an expense over the requisite service period. As of December 31, 2016, the Company has earlyadopted the policy to account for forfeitures as they occur according to the FASB’s Accounting Standards Update (ASU) 2016-09, Improvements toEmployee Share-Based Payment Accounting. The adjustment for the beginning of the period was not material and therefore it was not reflected in theconsolidated statements of changes in shareholders’ equity.The Company elected to recognize compensation costs for awards conditioned only on continued service that have a graded vesting schedule using thestraight-line method and to value the awards based on the single-option award approach. Performance based awards are expensed over the requisite serviceperiod when the achievement of performance criteria is probable.Equity awards granted to non-employees are re-measured at each reporting period at fair value until the commitment date had been reached which is usuallythe date the service is completed. The fair value of equity awards is charged to the statement of operations over the service period using the straight-linemethod.F-9UROGEN PHARMA LTD.NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(U.S. dollars in thousands, except share and per share data) k. Revenue recognitionVirtually all the Company’s revenues are derived from the license agreement with Allergan, to license worldwide rights to some of its products. See also Note1. Revenue is recognized only when all of the following conditions have been met: (i) there is persuasive evidence of an arrangement; (ii) delivery hasoccurred: (iii) the fee is fixed or determinable: and (iv) collectability of the fee is reasonably assured.The license agreement contains two deliverables: (a) the license component and (b) Allergan’s right to require supply services of RTGel vials from theCompany.In an arrangement with multiple deliverables, the delivered item or items shall be considered a separate unit of accounting if all of the following criteria aremet:(a) The delivered item or items have value to the customer on a standalone basis. The item or items have value on a standalone if they are sold separately byany vendor or the customer could resell the delivered item(s) on a standalone basis. In the context of a customer’s ability to resell the delivered item(s), thiscriterion does not require the existence of an observable market for the deliverable(s), and(b) If the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item or items isconsidered probable and substantially in the control of the vendor.When deliverables are separable, arrangement consideration is allocated to the separate units of accounting based on the relative selling price of eachdeliverable (where the amount allocable to the delivered element is limited to the amount not contingent on the delivery of future products or services) andthe appropriate revenue recognition principles are applied to each unit.The license component has standalone value (and therefore is accounted for separately from the supply services) since Allergan can use the license for itsintended purposes without the Company’s supply services. The four conditions of ASC 605 were met as of December 31, 2017 and 2016: (1) persuasiveevidence of an arrangement exists since the Company and Allergan engaged with a binding agreement; (2) delivery has occurred or services have beenrendered since all documents and data Allergan has requested relating to the Company’s know-how were provided before December 31, 2016 and Allergancan use the license for its intended purposes without the supply services (except for immaterial support services); (3) the fee is fixed or determinable, asindicated in the license agreement; and (4) collectability is reasonably assured.The Company is also entitled to milestone payments and royalties based on Allergan’s revenue from its product, which are not considered fixed ordeterminable until their occurrence. Therefore, these amounts would only be recognized when the conditions for payment are met, and they become due andpayable.During October 2016, the consideration received in the amount of $17.5 million represented arrangement consideration for both the license of theintellectual property as well as Allergan’s right to future supply services (which would be provided in consideration for future payments to the Companyaccording to the pricing stipulated in the supply agreement). The Company determined that the pricing of the supply services represents their standaloneselling price. Accordingly, the Company allocated the entire upfront fee of $17.5 million to the license component. In addition, revenue from the supplyservices would be recorded in an amount equal to the consideration stipulated in the agreement for these services, when these services are provided.During July 2017, the Company earned a milestone payment of $7.5 million resulting from Allergan’s submission of an IND application for the Company’sRTGel in combination with Allergan’s BOTOX for the treatment of overactive bladder to the U.S. FDA. The Company received the milestone payment inAugust 2017. This milestone was recognized as revenue during the year ended December 31, 2017, as conditions for payment were met and the milestonepayment was considered fixed or determinable. l. Research and development costsResearch and development costs are expensed as incurred and consist primarily of the cost of salaries, share-based compensation expenses, payroll taxes andother employee benefits, subcontractors and materials used for research and development activities, including preclinical studies, clinical trials,manufacturing costs and professional services. The costs of services performed by others in connection with the research and development activities of anentity, including research and development conducted by others onF-10UROGEN PHARMA LTD.NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(U.S. dollars in thousands, except share and per share data) behalf of the entity, shall be included in research and development costs. Grants received from the Israel Innovation Authority, f/k/a the Office of the ChiefScientist of Israel’s Ministry of Industry, Trade and Labor (the “IIA”) are recognized when the grant becomes receivable, provided there is reasonableassurance that the Company will comply with the conditions attached to the grant and there is reasonable assurance the grant will be received. The grant isdeducted from the research and development expenses as the applicable costs are incurred. In the year ended December 31, 2016, the Company had anincrease of $175 to its research and development expenses as a result of its decision not to pursue one of its research programs that had been approved as aresult of other financing opportunities. For the year ended December 31, 2016 an amount of $126 was received from Allergan, in connection with the pre-clinical collaboration agreement signed in August 2015 and deducted from the research and development expenses.The costs of intangibles that are purchased from others for a particular research and development project and that have no alternative future uses (in otherresearch and development projects or otherwise) and therefore no separate economic values are research and development costs at the time the costs areincurred. m. Income tax1) Deferred taxesDeferred taxes are computed using the asset and liability method. Under the asset and liability method, deferred income tax assets and liabilities aredetermined based on the differences between the financial reporting and tax bases of assets and liabilities and are measured using the currently enacted taxrates and laws. A valuation allowance is recognized to the extent that it is more likely than not that the deferred taxes will not be realized in the foreseeablefuture.2) Uncertain income tax positionsThe Company follows a two-step approach in recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognitionby determining if the available evidence indicates that it is more likely than not that the position will be sustained based on technical merits. If this thresholdis met, the second step is to measure the tax benefit as the largest amount that is more likely than not of being realized upon ultimate settlement. As ofDecember 31, 2017 and 2016, the Company had not accrued a provision for uncertain tax positions.n. Loss per shareBasic loss per share (“LPS”) is computed by dividing net loss for the year, after reducing cumulative dividends on preferred shares, by the weighted averagenumber of ordinary shares of the Company outstanding for each period.The calculation of diluted net loss per share excludes potential share issuances of ordinary shares upon the exercise of share options, warrants for preferredshares and convertible preferred share as each of their effect is anti-dilutive.o. Fair value measurementFair value is based on the price that would be received from the sale of an asset or that would be paid to transfer a liability in an orderly transaction betweenmarket participants at the measurement date. In order to increase consistency and comparability in fair value measurements, the guidance establishes a fairvalue hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described as follows:Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives thehighest priority to Level 1 inputs.Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data.Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservableinputs to the extent possible and considers counterparty credit risk in its assessment of fair value.F-11UROGEN PHARMA LTD.NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(U.S. dollars in thousands, except share and per share data) p. Concentration of credit risksFinancial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents and short-terminvestments. The Company deposits cash and cash equivalents with highly rated financial institutions, and, as a matter of policy, limits the amounts of creditexposure to any single financial institution. The Company has not experienced any credit losses in these accounts and does not believe it is exposed tosignificant credit risk on these instruments.q. Segment reportingOperating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker, who is responsible forallocating resources and assessing performance of the operating segments. The Company operates in one operating segment.r. IPO CostsThe Company accounts for IPO costs in accordance with SEC Staff Accounting Bulletin Topic 5A. Costs directly attributable to a proposed or actual offeringof securities are deferred and recorded against the gross proceeds of the offering upon completion. During the year ended December 31, 2016, the Companyrecorded $1.7 million in general and administrative expenses related to IPO costs.s. Newly issued and recently adopted accounting pronouncements1)In August 2014, FASB issued Accounting Standards Update (“ASU”) No. 2014-15—Presentation of Financial Statements—Going Concern (ASCSubtopic 205-40): “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”. The update requires management to assess acompany’s ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. All entities are required to applythe new requirements in annual periods ending after December 15, 2016, and interim periods thereafter. The adoption of the guidance did not have amaterial impact on the Company’s financial statements.2)In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (“Topic 606”, “ASU 2014-09”, or “the New RevenueStandard”). ASU 2014-09 requires entities to recognize revenue that represents the transfer of promised goods or services to customers in an amountequivalent to the consideration to which the entity expects to be entitled to in exchange for those goods or services. The following steps should beapplied to determine this amount: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine thetransaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entitysatisfies a performance obligation. ASU 2014-09 supersedes the revenue recognition requirements in ASU 605, “Revenue Recognition,” and mostindustry-specific guidance in the Accounting Standards Codification. The New Revenue Standard is effective for the Company for annual reportingperiods, including interim periods therein, beginning January 1, 2018. The New Revenue Standard may be applied retrospectively with the cumulativeeffect recognized as of the date of adoption (modified retrospective method). The Company will adopt the New Revenue Standard using modifiedretrospective method. The Company has substantially completed its assessment of the New Revenue Standard and identified two revenue streams (1)licensing revenue and (2) revenue from clinical supply of RTGel per the license agreement with Allergan. The implementation of the New RevenueStandard will not have a material impact on the amount or timing of the Company’s current revenue recognition related to these revenue streams.3)In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842 or “ASU 2016-02”). ASU 2016-02 supersedes existing guidance in Leases(Topic 840). The revised standard requires lessees to recognize the assets and liabilities arising from leases with lease terms greater than twelve monthson the balance sheet, including those currently classified as operating leases, and to disclose key information about leasing arrangements. Lessees willbe required to recognize a lease liability and a right-of-use asset on their balance sheets, while lessor accounting will remain largely unchanged.

The A-1 warrants were classified as liabilities in accordance with ASC 480, as they were freestanding instruments, exercisable into Series A-1preferred shares, which were redeemable upon certain events that represent “Deemed Liquidation” events. Accordingly, the A-1 warrants were measured at fairvalue in every reporting period, and changes in their fair value were recognized in earnings within finance expenses, net.The fair value of the preferred share warrants as of December 31, 2016 was measured in accordance with the Hybrid Method. The Hybrid Method combinesthe probabilities of an IPO scenario which was estimated at 20% and a liquidation event scenario which was estimated at 80%. As of December 31, 2016 thefair value of the warrants for preferred shares was determined mainly based on estimation of the Company’s equity value derived from DCF calculation andon assumption relating to the future revenue forecast, clinical success probabilities, relevant discount rates between 10.5%-19% (10.5% for the cash flowexpected to be derived from the license agreement with Allergan and 19% for the cash flows expected to be derived from the Company’s internaldevelopment) and expected volatility at a rate of 73.93%.In connection with the completion of the IPO, the Company converted all outstanding warrants into 364,036 Preferred A-1 shares of the Company andsubsequently converted all of its preferred shares, including the Preferred A-1 shares, into ordinary shares.

Share-based compensationIn October 2010, the Company’s board of directors approved a share option plan (the “Plan”) for grants to Company employees, consultants, directors, andother service providers.The grant of options to Israeli employees under the Plan is subject to the terms stipulated by Section 102 of the Israeli Income Tax Ordinance (“Section102”). The option grants are subject to the track chosen by the Company, either the “regular income” track or the “capital gains” track, as set out in Section102. The Company registered the Plan under the capital gains track, which offers more favorable tax rates to the employees. As a result, and pursuant to theterms of Section 102, the Company is not allowed to claim as an expense for tax purposes the amounts credited to the employees in respect of options grantedto them under the Plan, including amounts recorded as salary benefits in the Company’s accounts, with the exception of the work-income benefit component,if any, determined on grant date. For non-employees and for non-Israeli employees, the Plan is subject to Section 3(i) of the Israeli Income Tax Ordinance.The expected volatility is based on the historical volatility of comparable companies. The risk-free interest rate assumption is based on observed interest ratesappropriate for the expected term of the options granted in dollar terms. The expected term is the length of time until the expected dates of exercising theoptions and is estimated for employees (except senior management) using the simplified method due to insufficient specific historical information ofemployees’ exercise behavior, and for non-employees, directors and senior management using the contractual term.In March 2017, the Company’s board of directors adopted the 2017 Equity Incentive Plan ("2017 Plan"), which was approved by the shareholders in April2017.

In addition, the number of ordinary shares reservedfor issuance under the 2017 Plan will automatically increase on January 1st of each calendar year, from January 1, 2018 through January 1, 2026, so that thenumber of such shares reserved for issuance will equal 12% of the total number of ordinary shares outstanding on the last day of the calendar month prior tothe date of each automatic increase, or a lesser number of shares determined by our board of directors. The maximum number of ordinary shares that may beissued upon the exercise of incentive stock options under the 2017 Plan is 5,600,000.The plan administrator determines the exercise price for stock options, within the terms and conditions of the 2017 Plan, provided that the exercise price of astock option generally cannot be less than 100% of the fair market value of our Ordinary Shares on the date of grant. Options granted under the 2017 Planvest at the rate specified in the stock option agreement as determined by the plan administrator.In April 2017, the Company’s board of directors approved modifications of performance conditions for 67,200 restricted stock units and contingent optionsfor executive management.

Tax ratesThe income of the Company is taxed at the regular rate. The corporate tax rate for 2017 was 24% and for 2016 was 25%.In December 2016, the Economic Efficiency Law (Legislative Amendments for Implementing the Economic Policy for the 2017 and 2018 Budget Year),2016 was published, introducing a gradual reduction in corporate tax rate from 25% to 23%. However, the law also included a temporary provision settingthe corporate tax rate in 2017 at 24%. As a result, the corporate tax rate was 24% in 2017 and would be 23% in 2018 and thereafter.The change in tax rate as mentioned above has not affected the Company since the Company has not recognized taxes to date in Israel.b.

The federal and state net operating losses begin toexpire after 2036. The Internal Revenue Code contains provisions that may limit the use of the net operating tax loss carryforward available if significant changes occur in thestock ownership of UPI. In the event UPI has had a change in ownership, utilization of the carry‑forwards could be restricted due to the “change in ownershipprovisions” under Section 382 of the Internal Revenue Code and similar state provisions. Such limitations could result in the expiration of the net operatingcarry‑forwards before their utilization.
