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 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).

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

Determine the dose that will be recommended for further study within the tumor types studied in this clinical trial 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).

Secondary Endpoints

Characterize the Volume of Distribution (Vd) of HWK-007 (ADC, total antibody, CPT116, and CPT119)

Frequently asked questions about HWK-007

What is HWK-007 used for?

HWK-007 is an investigational small molecule being developed for the treatment of endometrial cancer. It is also being studied in other advanced solid tumors, including ovarian cancer and non-squamous EGFR wild-type non-small cell lung cancer. The drug is currently in Phase 1 clinical development.

What does HWK-007 target?

HWK-007 targets PTK7, a protein involved in tumor growth and progression. It is designed as a PTK7-directed antibody drug conjugate, which means it delivers a cytotoxic agent to cancer cells that express PTK7. This mechanism is being evaluated in a Phase 1 clinical trial for advanced solid tumors.

Who makes HWK-007?

HWK-007 is being developed by Whitehawk Therapeutics, Inc., a biopharmaceutical company traded on the stock exchange under the ticker symbol WHWK. The company is conducting a Phase 1 clinical trial to evaluate the safety and efficacy of HWK-007 in participants with advanced solid tumors.

What phase is HWK-007 in?

HWK-007 is in Phase 1 clinical development. It is an investigational drug that has not yet been approved by regulatory authorities. The ongoing Phase 1 trial is recruiting participants to assess the safety, tolerability, and preliminary efficacy of HWK-007 in advanced solid tumors.

What clinical trials is HWK-007 in?

HWK-007 is being studied in a Phase 1 clinical trial with the identifier NCT07444814. This trial is evaluating the safety and efficacy of HWK-007 in participants with advanced solid tumors, including endometrial cancer, ovarian cancer, and non-squamous EGFR wild-type non-small cell lung cancer. The trial is currently recruiting in the United States.
