MAT2A inhibitor AG-270/S095033 in patients with advanced malignancies: a phase I trial.

ABSTRACT: Homozygous MTAP deletion occurs in ~15% of cancers, making them vulnerable to decreases in the concentration of S-adenosylmethionine (SAM). AG-270/S095033 is an oral, potent, reversible inhibitor of methionine adenosyltransferase 2 A (MAT2A), the enzyme primarily responsible for the synthesis of SAM. We report results from the first-in-human, phase 1 trial of AG-270/S095033 as monotherapy in patients with advanced malignancies (ClinicalTrials.gov Identifier: NCT03435250). Eligible patients had tumors with homozygous deletion of CDKN2A/MTAP and/or loss of MTAP protein by immunohistochemistry. Patients received AG-270/S095033 once daily (QD) or twice daily (BID) in 28-day cycles. The primary objective was to assess the maximum tolerated dose (MTD) of AG-270/S095033.
