Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to characterize the safety, tolerability, and efficacy of IDE161 as a single agent and in combination with pembrolizumab.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 and in combination with pembrolizumab in participants with advanced/recurrent endometrial cancer.
