- 15Our future success is dependent on the marketing authorization of our product candidates

- 17Our T-cell immunotherapy product and product candidates represent new therapeutic approaches that could result in heightened regulatory scrutiny, delays in clinical development or our inability to achieve regulatory approval, commercialize or secure payor coverage of our product candidates
- 18developing therapies for types of diseases beyond those initially addressed by our current product and product candidates
- 19The results of preclinical studies or earlier clinical studies are not necessarily predictive of future results. Our existing product candidate in clinical studies, and any other product candidate we advance into clinical studies, may not have favorable results in later clinical studies or receive regulatory approval
- 20Interim “top line” and preliminary data from clinical studies that we or our partners may announce or share with regulatory authorities from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data

- 30Failure to obtain regulatory or payor approval in international jurisdictions would prevent our product candidates from being marketed abroad
- 31The proposed revision of the European legislation on pharmaceuticals, changes in governmental administration or changes in leadership at relevant agencies could lead to uncertainties over the regulatory framework that will be applicable to medicinal products in the EU and US, including orphan medicinal products

Risks Related to Our Intellectual Property
- 44If we are unable to obtain and maintain sufficient intellectual property protection for our product candidates, or if the scope of the intellectual property protection is not sufficiently broad, our ability to commercialize our product candidates successfully and to compete effectively may be adversely affected
- 45If we are sued for infringing the intellectual property rights of third parties, the resulting litigation could be costly and time-consuming and could prevent or delay our or our partners’ development and commercialization efforts

- 56Price controls may be imposed in foreign markets, which may adversely affect our future profitability

- 58We are subject to certain contractual obligations under our royalty financing agreement with HealthCare Royalty Partners and may be subject to claims for damages if we fail to fulfill these obligations
- 59We expect the product candidates we develop will be regulated as biological products (biologics) and therefore they may be subject to competition sooner than anticipated

- 70Some terms of our charter documents and Delaware law may have anti-takeover effects that could discourage an acquisition of us by others, even if an acquisition would be beneficial to our stockholders and may prevent attempts by our stockholders to replace or remove our current management
- 71Any of the factors listed above may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, who are responsible for appointing the members of our management
- 72We qualify as a “smaller reporting company” and a “non-accelerated filer,” and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to such companies could make our common shares less attractive to investors
- 73If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline
- 74Our future success depends on our ability to retain our executive officers and to attract, retain and motivate qualified personnel
