TNG456 is a next-generation, brain-penetrant, MTA-cooperative PRMT5 inhibitor for the treatment of solid tumors, including glioblastoma, with MTAP loss (SNO 2025) - P1/2 | "TNG908, TNG462, AMG 193, BMS-986504, and AZD3470 were the first MTA-cooperative PRMT5 inhibitors entered in clinical trials for the treatment of solid tumors with MTAP loss, though only TNG908 and AMG 193 are reported to be brain-penetrant in preclinical species. TNG456 is currently enrolling patients with MTAP-null solid tumors, including glioblastoma, in a Phase 1/2 clinical study (NCT06810544). 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 glioblastoma and CNS metastases."

The phase 1/2 combination study of vopimetostat with RAS(ON) multi-selective inhibitor daraxonrasib, and RAS(ON) G12D-selective inhibitor zoldonrasib (both from Revolution Medicines, RVMD), is ongoing with robust enrollment in previously treated MTAP-del/RAS mut pancreatic and lung cancer. (The Manila Times) - "The first dose escalation cohort of this study has been fully enrolled (n=7) and backfill is ongoing. Vopimetostat in combination with both daraxonrasib and zoldonrasib have been well-tolerated to date with exposures in the active range for each compound. The second cohort was initiated in early October. A cohort of 1L patients is expected to begin enrolling after go-forward doses have been selected. The data from this study have the potential to support a pivotal study in 1L MTAP-del/RAS mut pancreatic cancer. Initial data from the Phase 1/2 study are anticipated in 2026."

Epigenetic silencing of MTAP defines a distinct class of PRMT5-inhibitor-sensitive cancers (AACR-NCI-EORTC 2025) - "This metabolic vulnerability renders MTAP-deficient tumors selectively sensitive to PRMT5 inhibitors such as TNG-462 and TNG-908. We identify promoter hypermethylation as a distinct mechanism of MTAP silencing, broadening the spectrum of MTAP-low tumors beyond genomic loss. These findings support integration of epigenetic biomarkers to refine patient selection and enhance response rates in PRMT5-targeted clinical trials."

Tango Therapeutics Reports Positive Data from Ongoing Phase 1/2 Study with Vopimetostat (TNG462) in Patients with MTAP-deleted Cancers (The Manila Times) - "Across the 16 cancer types enrolled in the trial, the ORR is 27% in patients with a median follow-up of 9.4 months, which supports the potential for vopimetostat as the best-in-class PRMT5 inhibitor. In 2L MTAP-deleted pancreatic cancer, the median PFS is 7.2 months and the ORR is 25%, more than double that observed in historical control studies, supporting our decision to initiate a pivotal trial in this patient population in 2026.

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."

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."
