Brief Summary:

This study is a Phase 1b/2a basket trial to assess safety and efficacy of IDX-1197 in patients with HRR mutation.

There are two parts to this study: Phase 1b, IDX-1197 dose-selection study to determine RP2D and Phase 2a, non-randomized parallel dose expansion study to confirm RP2D.
