MUC16-targeted antibody-drug HWK-016 for advanced ovarian and endometrial cancer

A Phase 1 First-in-Human Study of MUC16-Directed Antibody Drug Conjugate HWK-016 in Participants With Advanced Solid Tumors.

Phase 1 Interventional Whitehawk Therapeutics, Inc. · NCT07470853

This will test HWK-016, an antibody-drug that targets MUC16, in adults with advanced or metastatic ovarian or endometrial cancer, including platinum-resistant ovarian cancer.

What this trial studies

This first-in-human, open-label Phase 1 program uses dose escalation followed by dose expansion to define a safe dose and characterize activity of HWK-016, a MUC16-directed antibody-drug conjugate. The trial has two parts: Part A tests HWK-016 alone in ovarian and endometrial cancer cohorts, and Part B tests HWK-016 combined with bevacizumab in ovarian cancer cohorts. There is no randomized control arm; safety, tolerability, pharmacokinetics, and preliminary anti-tumor activity will guide dose decisions and expansion cohort selection. The multicenter design enrolls patients at several U.S. cancer centers.

Who should consider this trial

Good fit: Adults with advanced or metastatic ovarian or endometrial cancer (including platinum-resistant ovarian cancer) who meet the study's safety criteria and do not have uncontrolled CNS disease or major cardiac, pulmonary, or ocular conditions are potential candidates.

Not a fit: Patients with uncontrolled central nervous system metastases, active serious infections, significant cardiovascular disease, corneal keratopathy, a history of pneumonitis/interstitial lung disease, or who are pregnant or breastfeeding are unlikely to be eligible or to benefit from participation.

Why it matters

Potential benefit: If successful, HWK-016 could offer a new treatment option that shrinks tumors or slows progression for patients with MUC16-expressing advanced ovarian or endometrial cancers.

How similar studies have performed: Antibody-drug conjugates and other MUC16-targeted approaches have shown early promise in oncology, but HWK-016 is first-in-human and its safety and efficacy are unproven.
