IDEAYA Announces Clinical Trial Collaboration with Amgen to Evaluate MAT2A-PRMT5 Synthetic Lethality Combination in MTAP Deleted Tumors
IDEAYA Biosciences announced a clinical trial collaboration with Amgen to evaluate IDE397, a MAT2A inhibitor, in combination with Amgen's AMG 193, targeting MTAP-null solid tumors. This partnership aims to explore the efficacy of this first-in-class synthetic lethality combination, expected to impact approximately 15% of solid tumors. Amgen will sponsor the Phase 1 trial, sharing costs with IDEAYA, while both companies retain commercial rights to their respective therapies. IDEAYA continues its ongoing Phase 1/2 trial for IDE397, evaluating it in various cancer settings.
- Collaboration with Amgen enhances clinical evaluation capabilities for IDE397.
- Potential first-in-class synthetic lethality combination targeting MTAP-null tumors.
- IDE397 is part of an ongoing Phase 1/2 clinical trial, reflecting ongoing development.
- Risks associated with clinical trial outcomes and regulatory approvals.
- Uncertainty regarding the effectiveness of IDE397 as part of combination therapy.
- Entered into Clinical Trial Collaboration and Supply Agreement with Amgen to clinically evaluate IDE397, IDEAYA's investigational MAT2A inhibitor, in combination with AMG 193, Amgen's investigational MTA-Cooperative PRMT5 inhibitor, in MTAP-null solid tumors
- Potential first-in-class Synthetic Lethality (SL-SL) Combination targets two distinct, mechanistically complementary, nodes of MTAP methylation pathway
- MTAP deletion patient population is estimated to represent approximately
15% of solid tumors, reflecting the potential for significant patient impact with the SL-SL combination - Amgen will sponsor the Phase 1 clinical combination trial with IDEAYA and Amgen jointly sharing costs of the study
SOUTH SAN FRANCISCO, Calif., July 27, 2022 /PRNewswire/ -- IDEAYA Biosciences, Inc. (Nasdaq:IDYA), a synthetic lethality focused precision medicine oncology company committed to the discovery and development of targeted therapeutics, announced it has entered into a clinical trial collaboration and supply agreement with Amgen Inc. to evaluate the efficacy and safety of IDE397, its investigational, potential best-in-class, small molecule MAT2A inhibitor, with Amgen's AMG 193, an investigational small molecule MTA-cooperative inhibitor of PRMT5, in a Phase 1 clinical trial.
"This clinical collaboration with Amgen builds on IDEAYA's ongoing clinical evaluation of IDE397 as monotherapy and in selected combinations in our Phase 1/2 clinical trial, including with taxanes and pemetrexed. We are pleased to collaborate with Amgen to also evaluate the MAT2A-PRMT5 synthetic lethality combination in the clinic," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences.
"Mechanistically, each of MAT2A and PRMT5 are synthetic lethal with MTAP gene deletion in tumors. The synthetic lethality of each of these targets provides a complementary approach for targeting MTAP-null tumors," said Dr. Michael White, Ph.D., Senior Vice President and Chief Scientific Officer, IDEAYA Biosciences.
IDE397 is a potent and selective small molecule inhibitor targeting methionine adenosyltransferase 2a (MAT2A), in patients having solid tumors with methylthioadenosine phosphorylase (MTAP) deletion. The MTAP deletion patient population is estimated to represent approximately
IDEAYA is evaluating IDE397 in an ongoing Phase 1/2 clinical trial. The company has initiated and is actively enrolling patients into monotherapy expansion and combination cohorts of the IDE397 Phase 1 clinical trial, including in combination with docetaxel in NSCLC, paclitaxel in esophagogastric cancer and pemetrexed in NSCLC. IDEAYA is leading early clinical development of IDE397 in collaboration with GSK. Subject to exercise of its option, GSK will lead later-stage clinical development of IDE397.
Amgen is developing AMG 193, an investigational small molecule methylthioadenosine (MTA) cooperative inhibitor targeting protein arginine methyltransferase 5 (PRMT5), as monotherapy and in combination with docetaxel in MTAP null solid tumors, in an ongoing Phase 1 clinical trial.
Under the mutually non-exclusive clinical trial collaboration and supply agreement, IDEAYA will provide IDE397 drug supply to Amgen, who will be the sponsor of the Phase 1 clinical combination trial. IDEAYA and Amgen will jointly share external costs of the clinical trial and will jointly oversee clinical development of the combination therapy. IDEAYA and Amgen each retain all commercial rights to their respective compounds, including as monotherapy or as combination therapies.
