Current report
Certain of our current and future product candidates are being used in combination or we anticipate could be used in combination with third-party drugs or biologics, some of which are still in development, and we have limited or no control over the supply, regulatory status, or regulatory approval of such other drugs or biologics.
Current report
Certain of our current product candidates are being administered or may have the potential to be administered in combination with existing standards of care (such as checkpoint inhibitor immunotherapies, chemotherapies, targeted therapies, or radiotherapy) or with other classes of therapeutics agents (such as the RAS(ON) multi- and G12D- inhibitors from Revolution Medicines with which we are evaluating vopimetostat in combination clinical trials and abemaciclib, with which we plan to evaluate TNG456 in a combination clinical trial). Our ability to develop and ultimately commercialize our current programs and product candidates and any future programs or product candidates for use in combination with other therapies will depend on our ability to access such drugs or biologics on commercially reasonable terms for the clinical trials and their availability for use with our commercialized product, if approved. We have entered into separate clinical collaboration and supply agreements with Revolution Medicines, Lilly, and Erasca, under which we are conducting or plan to conduct combination clinical trials with Revolution Medicines’ RAS(ON) multi- and G12D-selective inhibitors, Lilly’s abemaciclib, and Erasca’s pan-RAS molecular glue, ERAS-0015, respectively. Additionally, we have purchased pembrolizumab for use in combination with vopimetostat. Nevertheless, we cannot be certain that current or potential future commercial relationships will continue to provide us with a steady supply of such drugs or biologics on commercially reasonable terms, or at all. In particular, we plan to initiate a global, randomized registrational trial evaluating the combination of vopimetostat with daraxonrasib in front-line patients with MTAP-deleted PDAC in the first half of 2027. While we are pursuing multiple pathways to obtain clinical supply of daraxonrasib for the planned trial, there is no assurance that we will be able to secure clinical supply of daraxonrasib on our anticipated timeline, on commercially reasonable terms, or at all.
Current report
Any failure to maintain or enter into new commercial relationships, or the expense of purchasing checkpoint inhibitor immunotherapies or other potential combination or comparator therapies in the market, may delay our development timelines, increase our costs, and jeopardize our ability to develop our current product candidates and any future product candidates as commercially viable therapies. If any of these circumstances occur, our business, financial condition, operating results, stock price, and commercial prospects may be materially harmed.
Current report
Effective August 6, 2026, our Board of Directors appointed Robert Azelby as Chair of the Board of Directors.
