Phase 1
Recruiting
Conditions
Solid Tumor
Interventions
Registration Number
NCT04794699
Lead Sponsor
IDEAYA Biosciences
Brief Summary

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 other anticancer agents including taxanes (docetaxel, paclitaxel), or 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).

Objective Response Rate (ORR) and Duration of Response (DoR)

Dose-limiting Toxicities (DLTs) of IDE39721 days following the first dose of IDE397

Incidence of DLTs of IDE397 will be determined

Dose-limiting Toxicities (DLTs) of IDE397 in combination with docetaxel or paclitaxel or sacituzumab govitecan21 - 28 days following the first dose of IDE397

Incidence of DLTs of IDE397 in a combination setting will be determined

Maximum Tolerated Dose (MTD) and/or Recommended Phase 2 Dose (RP2D) of IDE397Approximately 2 years

MTD and RP2D of IDE397 will be determined

Maximum Tolerated Dose (MTD) and/or Recommended Phase 2 Dose (RP2D) of IDE397 in combination with docetaxel or paclitaxel or sacituzumab govitecanApproximately 2 years

MTD and RP2D of IDE397 in a combination setting will be determined

Secondary Outcome Measures
NameTimeMethod
Drug interaction between IDE397 and docetaxel or paclitaxel or sacituzumab govitecanApproximately 2 years

Pharmacokinetics of docetaxel or paclitaxel or sacituzumab govitecan.

Plasma Pharmacokinetics of IDE397 and metaboliteApproximately 2 years

Pharmacokinetics of IDE397 and metabolite following single and multiple oral administration as a single agent and in combination with docetaxel or paclitaxel or sacituzumab govitecan, will be determined

Pharmacodynamic effect of IDE397 as a single agent and in combination with docetaxel or paclitaxel or sacituzumab govitecanApproximately 2 years
