Clinical Trial Summary

The purpose of this study is to characterize the safety, tolerability, and efficacy of IDE161.

Description:

The purpose of this study is to characterize the safety, tolerability including determination of maximum tolerated dose (MTD), maximum accepted dose (MAD), recommended dose(s) for expansion (RDE) and/or recommended Phase 2 dose (RP2D), pharmacokinetics (PK), pharmacodynamics (PD) and preliminary anti-tumor activity of IDE161 as a single agent in participants with advanced or metastatic solid tumors harboring BRCA1/2 loss of function alterations and/or other defects in the homologous recombination (HR) pathway.
