Summary
Brief summary
The purpose of this study is to assess the safety, tolerability and preliminary efficacy of CYH33 in combination with olaprib in patients with DDR gene mutations and/or PIK3CA mutations, in patients who have progressed on prior PARP inhibitor, and in patients with recurrent high grade serous ovarian, fallopian tube, or primary peritoneal cancer who are platinum resistant or refractory. The study will assess if this combination will optimize anti-tumor activity, block tumor growth and overcome the resistance to PARP inhibitor treatment. The study consists 2 parts. In Part 1 dose escalation, the objective is to determine the maximum toleration dose (MTD) of the combination. The final recommended phase 2 dose (RP2D) of CYH33 in combination with olaparib will be based on the totality of an overall assessment of available safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy which could be the MTD or a dose level lower in specific cohorts of patients. In Part 2 dose expansion, the main objective is to evaluate the efficacy at RP2D.
