EIK1003-001: This study is recruiting people with recurrent, advanced or metastatic breast cancer, ovarian cancer or metastatic castration resistant prostate cancer, and aims to determine the safety, efficacy and recommended dose level of a new targeted therapy drug (called IMP1734)A First-in-human, Phase 1/2, Open-label, Multi-center, Dose-escalation, Dose-optimization, and Dose-expansion Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Anti-tumor Activity of PARP1 Selective Inhibitor, IMP1734, as Monotherapy in Patients With Advanced Solid Tumors

Clinical summary

Summary

This study consists of three parts: Dose Escalation, Dose Optimisation and Dose Expansion. 

In Dose Escalation (Part 1), the study will identify the maximum tolerated dose (MTD) or maximum achievable dose (MAD). 

In Dose Optimisation (Part 2), the study will further evaluate how safe, tolerable and effective select doses of IMP1734 are.

In Dose Expansion (Part 3), the recommended dose escalation (RDE) of IMP1734 monotherapy will be evaluated.

IMP1734, which is a PARP1 selective inhibitor, will be administered as oral daily tablets. The maximum trial duration is three years after the last participant's first treatment in the trial. 

Conditions

This trial is treating patients with breast cancer, ovarian cancer or metastatic castration resistant prostate cancer (mCRPC) with deleterious/suspected deleterious mutations of select homologous recombination repair (HRR) gene mutations
