|Condition or disease||Intervention/treatment||Phase|
|Ovarian Cancer Breast Cancer Solid Tumor Prostate Cancer Endometrial Cancer||Drug: CYH33||Phase 1|
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||350 participants|
|Intervention Model:||Sequential Assignment|
|Intervention Model Description:||Open-label, multicenter study which is composed of 2 parts: 1.) dose escalation and 2.) dose expansion. Bayesian optimal interval (BOIN) design will be used to determine the MTD and/or RP2D. Safety, tolerability, PK, PD, and clinical activity will also be evaluated. The CYH33 starting dose of this trial is 20 mg QD in combination with olaparib 300 mg BID. Two additional dose levels of CYH33 at 30 mg QD and 40 mg QD in combination with olaparib 200 mg BID will be evaluated. In the initial dose cohort of 20 mg CYH33 as well as in subsequent dose cohorts 20 and 30 mg QD and 40 mg QD in combination with olaparib 200 mg BID, 3 patients will be initially enrolled at each dose level of CYH33. These evaluable patients will be included into this dose level for decision making on dose selection for the next cohort. 10 mg QD of CYH33 will be evaluated in the combination with olaparib 200 mg BID, according to the BOIN design.|

Experimental: CYH33 in Combination with Olaparib
CYH33 in Combination with Olaparib; 20 mg CYH33 QD in combination with olaparib 300 mg BID. Additional dose levels of CYH33 at20 and 30 mg QD and CYH33 at 40 mg QD in combination with olaparib 200 mg BID will be evaluated.
