A Study of PARP1 Selective Inhibitor, EIK1004 (IMP1707) in Participants With Advanced Solid Tumors.
Purpose
This study will evaluate the safety, tolerability, and preliminary efficacy of EIK1004 (IMP1707) in participants with recurrent advanced/metastatic breast cancer, ovarian cancer, metastatic castrate resistant prostate cancer (mCRPC) and pancreatic cancer with deleterious/suspected deleterious mutations of select homologous recombination repair (HRR) genes.

Detailed Description
This study will evaluate the safety, tolerability and preliminary efficacy of EIK1004 (IMP1707) as monotherapy in patients with recurrent, advanced/metastatic solid tumors. The study consists of 2 parts: Dose escalation and dose optimization. In dose escalation (Part1), the study will identify the maximum tolerated dose (MTD) or maximum achievable dose (MAD) in solid tumor. In dose optimization (Part 2), the study will further evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and anti-tumor activity of select doses of EIK1004 (IMP1707)
