CA240-0007: BMS-986504 With Anti-PD-1 or Chemotherapy as Treatment for Advanced Solid Tumors With Homozygous MTAP Deletion (Exhibit Hall Rows 28-36) - Jul 22, 2025 - Abstract #IASLCWCLC2025IASLC_WCLC_2035; P1 Exclusion criteria specific to the PDAC substudy include a history of select lung diseases, connective tissue disorders, peripheral artery disease, chronic leukemias, or the ongoing need for warfarin or for a treatment known to inhibit or induce cytochrome P450 3A4 or 2C8 that cannot be switched to an alternative treatment prior to study entry...Further substudies with BMS-986504 combination regimens are planned. The combination substudies are currently recruiting, and approximately 155 patients will be enrolled across all substudies.
- |||||||||| MTAPloss Is Frequent and Potentially Targetable With PRMT5 Inhibitors in Oncogene-Driven NSCL (Exhibit Hall) - Jul 22, 2025 - Abstract #IASLCWCLC2025IASLC_WCLC_1874;
MRTX1719 monotherapy showed IC50 <0.5 ?M in 5/7 EGFR + MTAP -deleted models, and <0.16 ?M in all 5 ALK + MTAP -deleted lines...Preclinical data suggest that oncogene-driven tumors with MTAP loss are sensitive to single agent PRMT5 inhibitors and that combination TKI and PRMT5 inhibitors may have additive or synergistic antitumor activity. These findings support clinical testing of combined TKI and PRMT5 inhibitors in oncogene-driven MTAP deleted NSCLC.

TNG456 is a next-generation, brain-penetrant, MTA-cooperative PRMT5 inhibitor for the treatment of solid tumors with MTAP loss (Section 20; Poster Board No: 23) - Mar 25, 2025 - Abstract #AACR2025AACR_3155; Oral administration of TNG456 drives dose-dependent antitumor activity including durable tumor regressions and complete responses in multiple cell line- and patient-derived xenograft models. With enhanced potency and selectivity for MTAP-null cancer cells, and strong preclinical evidence of brain-penetrance, TNG456 has the potential for broad clinical activity in MTAP-null solid tumors including gliomas and CNS metastases.

Additionally, OncoKB included KRAS G12C in colorectal cancer and IDH1 mutations in myelodysplastic syndromes as Level 1 following FDA approval of adagrasib + cetuximab and ivosidenib, respectively...Lastly, novel biomarkers including FBXW7 and PPP2R1A alterations (endometrial and ovarian cancer), SMARCA4 mutations (non-small cell lung cancer and esophageal adenocarcinoma) and MTAP deletions (all solid tumors) were included in OncoKB based on compelling preclinical and emerging clinical evidence in association with lunresertib + camonsertib, PRT3789, and AMG193 and MRTX1719, respectively...OncoKB also implemented major software updates to support data integration into the EPIC platform. Future OncoKB efforts are focused on whole genome/exome curation, inclusion of biomarkers for non-NGS-based precision oncology therapies, and the development of a clinical trial matching system.

Discovery of novel MTA-cooperative PRMT5 inhibitors as targeted therapeutics for MTAP-deleted cancers (Section 24) - Mar 5, 2024 - Abstract #AACR2024AACR_6897; The correlation between compound exposure and on-target effect was confirmed in PK/PD and efficacy studies. Taken together, these studies confirm that MTA cooperative PRMT5 inhibitors exert strong synthetic lethal phenotype in MTAP deleted cancers and offer an exciting therapeutic opportunity for a large patient population.

P1/2 This renders selective targeting of MTAP null tumors with agents (MRTX1719, AMG193, TNG462, TNG908) targeting MTA bound PRMT5 (PRMT5:MTA), while sparing surrounding normal MTAP wild-type (WT) tissue...To address this pressing need, we co-treated CCA cell lines with MRTX1719 and PARP inhibitor olaparib...Similar differences in proportion of splicing events were also observed in MTAP loss CCA patient derived xenografts as compared to WT models. Collectively, these data implicate MTAP to be a crucial player in modulation of the chromatin and splicing events that may drive therapeutic response to PRMT5 inhibition.
