A First-in-human Study of PARP1 Selective Inhibitor, IMP1734, in Participants With Advanced Solid Tumors
Purpose
This study will evaluate the preliminary efficacy of IMP1734 in patients with recurrent advanced/metastatic breast cancer, ovarian cancer and metastatic castrate resistant prostate cancer (mCRPC) 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 IMP1734 as monotherapy in patients with recurrent, advanced/metastatic solid tumors. The study consists of 3 parts: Dose escalation, Dose Optimization and Dose expansion. 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 IMP1734. In dose expansion (Part 3) the recommended dose escalation (RDE) of IMP1734 monotherapy will be evaluated in patients with recurrent, advanced/metastatic breast cancer, ovarian cancer and mCRPC with deleterious/suspected deleterious mutations of select homologous recombination repair (HRR) gene mutations.
