Frequently asked questions about HWK-016

What is HWK-016?

HWK-016 is an investigational MUC16-directed antibody drug conjugate being developed by Whitehawk Therapeutics, Inc. (ticker WHWK) for advanced solid tumors, including platinum-resistant ovarian cancer (PROC), endometrial cancer, and other platinum-resistant ovarian cancer settings. It is currently in Phase 1 clinical development.

What is HWK-016 used for in PROC?

HWK-016 is being studied for use in platinum-resistant ovarian cancer (PROC) and other advanced solid tumors, including endometrial cancer. It is an investigational therapy and has not been approved for any indication. The ongoing Phase 1 trial is evaluating its use in participants with these tumor types.

What does HWK-016 target?

HWK-016 targets MUC16, a protein expressed on certain solid tumors. As a MUC16-directed antibody drug conjugate, it is designed to deliver a therapeutic payload to cells expressing MUC16. This targeted approach is being evaluated in a Phase 1 study in advanced solid tumors.

Who makes HWK-016?

HWK-016 is being developed by Whitehawk Therapeutics, Inc., which trades under the ticker WHWK. The company is responsible for the clinical development of this MUC16-directed antibody drug conjugate.

What phase is HWK-016 in?

HWK-016 is in Phase 1 clinical development. It is an investigational agent and has not been approved by the FDA for any indication. The Phase 1 trial is currently recruiting participants with advanced solid tumors.

What clinical trials is HWK-016 in?

HWK-016 is being evaluated in a Phase 1 clinical trial, NCT07470853, titled "A Study of MUC16-Directed Antibody Drug Conjugate HWK-016 in Participants With Advanced Solid Tumors." The trial is recruiting and has an estimated enrollment of 265 participants across sites in the United States.

Is HWK-016 the same as MUCIN-16-targeted ADC?

Yes, HWK-016 is also known as a MUCIN-16-targeted ADC. Both names refer to the same investigational antibody drug conjugate developed by Whitehawk Therapeutics, Inc. (WHWK) that targets MUC16.
