Study Endpoints
Primary Endpoints
Determine Maximum Tolerated Dose (MTD)
From Cycle 1, Day 1 Until Cycle 1, Day 21 (21-day cycles)

Determine the highest dose of HWK-016 that can be administered without signs of toxicity, measured at the end of Cycle 1(21-day cycle) by: Incidence and severity of Adverse Events (AE). Incidence of Dose-Limiting Toxicities (DLT). Incidence of Serious Adverse Events (SAE). Evaluate the safety and tolerability of HWK-016 at the selected RDE(s) determined from Phase 1a, as monotherapy (Part A) in participants with ovarian and endometrial cancers and in combination therapy with bevacizumab (Part B) in participants with ovarian cancer

Determine Maximum Administered Dose (MAD)
From Cycle 1, Day 1 to Cycle 1, Day 21 (21-day cycles) until the MTD is reached.

Determine the highest dose of HWK-016 administered during the dose escalation part of the study, measured at the end of Cycle 1 (21-day cycle) by: Incidence and severity of Adverse Events (AE). Incidence of Dose-Limiting Toxicities (DLT). Incidence of Serious Adverse Events (SAE). Evaluate the safety and tolerability of HWK-016 at the selected RDE(s) determined from Phase 1a, as monotherapy (Part A) in participants with ovarian and endometrial cancers and in combination therapy with bevacizumab (Part B) in participants with ovarian cancer

Determine Recommended Dose For Expansion (RDE)
From Cycle 1, Day 1 to Cycle 1, Day 21 (21-day cycle) until MTD is identified.

Determine the dose of HWK-016 that will be recommended for further study within the tumor types studied in this clinical trial, measured at the end of Cycle 1, Day 21 (21-day cycle) by: Incidence and severity of Adverse Events (AE). Incidence of Dose-Limiting Toxicities (DLT). Incidence of Serious Adverse Events (SAE). Evaluate the safety and tolerability of HWK-016 at the selected RDE(s) determined from Phase 1a, as monotherapy (Part A) in participants with ovarian and endometrial cancers and in combination therapy with bevacizumab (Part B) in participants with ovarian cancer.
