This is a Phase 1, open-label, multicenter, dose escalation and expansion study of the safety, PK, PD, and preliminary anti-tumor activity of IDE397 as a single agent and in combination with sacituzumab govitecan (SG), in adult patients with selected advanced or metastatic MTAP-deleted advanced solid tumors who are unresponsive to standard of care therapy. IDE397 is a small molecule inhibitor of methionine adenosyltransferase 2 alpha (MAT2A).
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
IDEAYA Biosciences (IDYA) is the sponsoring company for this trial. BiotechSign currently grades this company D (41/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
