HWK-007, a PTK7-targeted antibody‑drug conjugate for advanced PTK7-positive ovarian, endometrial, and certain non‑squamous lung cancers
Official title: A Phase 1 First-in-Human Study of PTK7-Directed Antibody Drug Conjugate HWK-007 in Participants With Advanced Solid Tumors
Run by Whitehawk Therapeutics, Inc. · NCT07444814 · Data updated 2026-11-12
This study will try HWK-007, a PTK7-targeted antibody‑drug conjugate given every three weeks, to see if it can shrink or control advanced PTK7-positive ovarian, endometrial, or non-squamous EGFR wild-type lung cancers.

Is this trial a fit for you?
✓Likely a good fit
Adults with advanced or metastatic PTK7-expressing non-squamous EGFR wild-type NSCLC, platinum-resistant ovarian cancer, or endometrial carcinoma who meet the study's safety and laboratory criteria and can attend site visits may be eligible.
✕Probably not a fit
Patients with uncontrolled CNS metastases, active uncontrolled infections, significant cardiac disease or prolonged QTc, corneal disease, unresolved toxicities from prior therapy, or who are pregnant are excluded and unlikely to benefit from participation.

What this trial studies
This first-in-human, open-label Phase 1 study uses sequential dose escalation (Phase 1a) followed by dose expansion (Phase 1b) without a control group to define a safe dose and gather early signs of anti-tumor activity and pharmacokinetics. HWK-007, a PTK7-directed antibody‑drug conjugate, is given by intravenous infusion every three weeks during the dose-escalation phase. Phase 1a enrolls patients with non-squamous EGFR wild-type NSCLC, platinum-resistant ovarian cancer, and endometrial carcinoma, and Phase 1b may open expansion cohorts for non-squamous EGFR WT NSCLC and other indications based on initial safety and activity. The trial is multicenter and will open cohorts at selected U.S. oncology centers.
Why it matters
Potential benefit: If successful, HWK-007 could become a new targeted treatment option that shrinks tumors or delays progression in patients with PTK7-expressing advanced solid tumors.
How similar studies have gone: Other early-phase antibody‑drug conjugates targeting PTK7 have shown preliminary signals of activity in solid tumors, but clinical benefit for this target class is not yet established.
