Detaljerad beskrivning

The purpose of this study is to evaluate safety, efficacy, and PK of IDE892 as monotherapy and combination therapy in adult participants with MTAP-deleted tumors who have progressed after standard therapy and represent a high unmet need. In the current stage, the combination will be focused on IDE892 with IDE397, an oral inhibitor of methionine adenosyltransferase 2A (MAT2A), to fully exploit the vulnerabilities associated with methylthioadenosine (MTA) accumulation in MTAP-deleted tumors while maintaining a substantial therapeutic index. The mechanistic rationale for this study is discussed in the following sections.
