Headings as the filing states them, in filing order.

Risks Related to Our Financial Position and Need for Capital

  1. 01We have incurred significant losses in every year since our inception. We may continue to incur losses over the next several years and may never achieve or maintain profitability
  2. 02Our future prospects are highly dependent on our ability to continue to successfully develop and execute our commercialization strategies for KIMMTRAK and any future products for which we may obtain regulatory approval. Failure to do so would adversely impact our financial condition and prospects
  3. 03Our ability to continue to generate revenues from KIMMTRAK and any other product candidates, if approved, is subject to being considered safe, effective, and having advantages over other therapies, and attaining and maintaining significant market acceptance among physicians, patients and healthcare payors
  4. 04Our revenues from KIMMTRAK may be significantly reduced by both existing and future legislation for drug pricing reforms requiring the payment of rebates
  5. 05We may require substantial additional funding to achieve our business goals. If we are unable to obtain this funding when needed and on acceptable terms, we could be forced to delay, limit or terminate our product development efforts
  6. 06Raising additional capital may cause dilution to our existing shareholders, restrict our operations or cause us to relinquish valuable rights

Risks Related to KIMMTRAK and the Development of Our Product Candidates

  1. 07In order to increase adoption and sales of KIMMTRAK, we will need to continue developing our commercial organization as well as recruit and retain qualified field representatives
  2. 08The incidence and prevalence for target patient populations for some of our product candidates have not been established with precision. If the market opportunities for our product candidates are smaller than we estimate, our revenue and ability to achieve profitability will be adversely affected, possibly materially

  6. 12We may be unable to successfully complete additional large-scale, pivotal clinical trials for any product candidates we develop
  7. 13Our product candidates utilize a novel mechanism of action and involve novel targets which may result in greater research and development expenses, regulatory issues that could delay or prevent approval, or discovery of unknown or unanticipated adverse effects

  10. 16If we experience delays in obtaining approval or if we fail to obtain approval of our product candidates, the commercial prospects for our product candidates may be harmed and our ability to generate revenues will be materially impaired
  11. 17Interim, “top-line” and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data
  12. 18We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates
  13. 19If we experience delays or difficulties in the enrollment of patients in clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented

  15. 21We are at risk of a clinical hold at any time based on the evaluation of the data and information submitted to the governing regulatory authorities
  16. 22Our product candidates may cause undesirable side effects or have other properties that could halt their clinical development, prevent their regulatory approval, require expansion of the trial size, limit their commercial potential, or result in significant negative consequences
  17. 23Our product candidates may have serious and potentially fatal cross-reactivity to other peptides or protein sequences within the body
  18. 24We intend to develop tebentafusp, brenetafusp and our other programs, and potentially future product candidates, in combination with other therapies, which exposes us to additional risks

There are a limited number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us

  4. 43We may become involved in lawsuits and/or administrative proceedings to protect or enforce our patents and other intellectual property rights, which could be expensive, time consuming and unsuccessful35% rewritten
  5. 44Intellectual property litigation and proceedings could cause us to spend substantial resources and distract our personnel from their normal responsibilities

  7. 46If we do not obtain patent term extension and data exclusivity for any product candidates we may develop, our business may be materially harmed

  3. 52Reports of adverse events or safety concerns involving KIMMTRAK or our product candidates could delay or prevent us from obtaining or maintaining regulatory approvals or could negatively impact sales of our products or the prospects for our product candidates
  4. 53The FDA and other regulatory authorities actively enforce the laws and regulations prohibiting the promotion of off-label uses
  5. 54Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of our product candidates in other jurisdictions

  11. 80Holders of our ADSs may not receive distributions on our ordinary shares represented by the ADSs or any value for them if it is illegal or impractical to make them available to holders of ADSs
