What the changes say

  • New disclosures highlight risks from the Inflation Reduction Act on small molecule drug pricing and Unified Patent Court challenges in Europe.
  • Additional focus centers on AI tool integration risks, third-party biomarker development, combination therapies like vopimetostat with RevMed inhibitors, and reliance on CROs for clinical trials.

What changed since the prior 10-K

New

  • NewRisks Related to the Development of our Precision Oncology and Other Programs and Product Candidates

    data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain regulatory approval of their product candidates

    We rely on third parties for biomarker testing to guide patient selection, and failing to secure these collaborations could hinder commercialization.

  • NewRisks Related to the Development of our Precision Oncology and Other Programs and Product Candidates

     factors we may not be able to control, including the impacts of any epidemics or pandemics, which may limit patients, principal investigators or staff or clinical site availability

    We test vopimetostat and TNG456 in combination trials with third-party drugs like RevMed's RAS inhibitors and abemaciclib, over which we have no supply control.

  • NewRisks Related to Our Reliance on Third Parties

    not be able to obtain regulatory approval for or commercialize our product candidates and our business could be substantially harmed

    We rely entirely on third-party contractors and academic institutions to conduct clinical trials for vopimetostat, TNG260, and TNG456 without independent control.

  • NewRisks Related to Our Intellectual Property

    patents (and we have received and may in the future receive notices offering the right to license certain technology to us) and third parties may in the future file civil lawsuits against us claiming infringement of their intellectual property rights

    Third parties may sue us for patent infringement regarding our precision oncology products, resulting in costly litigation or sales bans.

  • NewRisks Related to Our Intellectual Property

    patent. If we are forced to grant a license to third parties with respect to any patents we may own or license that are relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations, and prospects may be adversely affected

    Our European patents could face invalidity challenges across multiple countries simultaneously under the Unified Patent Court.

  • NewRisks Related to Government Regulation

    marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements

    The Inflation Reduction Act of 2022 allows CMS price setting for small molecule drugs nine years after approval, potentially lowering our future cash flows.

  • NewRisks Related to Employee Matters and Managing Anticipated Growth

    to enforcement or litigation in the event of any perceived non-compliance. Our vendors may in turn incorporate AI tools into their offerings, and the providers of these AI tools may not meet existing or rapidly evolving regulatory or industry standards, including with respect to privacy and data security

    The use of generative AI models internally and by vendors creates new cybersecurity attack surfaces, data leakage risks, and regulatory compliance challenges.

Dropped

  • DroppedRisks Related to the Development of our Precision Oncology and Other Programs and Product Candidates
