The Discovery of TNG456: A Highly Potent, Selective, Brain-Penetrant MTA-Cooperative PRMT5 Inhibitor for the Treatment of MTAP-Deleted Cancers. (PubMed, J Med Chem) - "Loss of MTAP leads to the accumulation of 5'-methylthioadenosine (MTA), which sensitizes tumor cells to inhibition of protein arginine methyltransferase 5 (PRMT5). Herein we describe the discovery of TNG456, a potent and highly selective MTA-cooperative PRMT5 inhibitor that is brain penetrant in preclinical species and currently in Phase I/II clinical studies for the treatment of advanced or metastatic solid tumors with MTAP loss, with a focus on glioblastoma."

TNG456 is a next-generation, brain-penetrant, MTA-cooperative PRMT5 inhibitor for the treatment of solid tumors with MTAP loss (AACR 2025) - "TNG908, TNG462, AMG 193, BMS-986504, and AZD3470 are clinical-stage MTA-cooperative PRMT5 inhibitors for the treatment of solid tumors with MTAP loss, though only TNG908 and AMG 193 are reported to be brain-penetrant. 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."

Evaluation of the impact of homozygous MTAP truncations on the clinical activity of MTA-cooperative PRMT5 inhibitors (AACR 2025) - "To benefit this large patient population, MTA-cooperative PRMT5 inhibitors, including TNG908, TNG462, and TNG456 were developed to leverage the synthetic lethal relationship between MTAP deletion and PRMT5 inhibition. Previously, we reported that homozygous loss of only the terminal exon (exon 8), an event reported to occur in only 0.5% of MTAP-deleted tumors, is insufficient for complete loss of MTAP activity in preclinical assays. Here, we report initial evidence for the clinical impact of MTAP truncations, as opposed to complete deletion, on the activity of MTA-cooperative PRMT5 inhibitors."

TNG462, an MTA-cooperative PRMT5 inhibitor, demonstrates strong efficacy in combination with clinically relevant targeted therapies in MTAP-null preclinical models (AACR 2025) - "This supports our clinical development plans for TNG462, which include targeted combinations with two RAS(ON) inhibitors, RMC-6236 and RMC-9805 from Revolution Medicines, as well as the EGFR inhibitor osimertinib from AstraZeneca...Significant efficacy was observed in preclinical models with the combination of TNG462 and CDK4/6 inhibitors, supporting a potential development path in GBM for our next generation CNS penetrant PRMT5 inhibitor, TNG456, with abemaciclib...However, TNG462 monotherapy at a clinically relevant dose achieved comparable benefits to the combination. Collectively, these findings strongly support evaluating TNG462 in combination with other targeted therapies in clinical trials for patients with cancers that exhibit MTAP loss."
