"We continue to dose escalate patients in our Phase 1 programs for HWK-007 and HWK-016 and remain on track to report initial data in the first half of 2027," said Dave Lennon, PhD, President and Chief Executive Officer of Whitehawk Therapeutics. "We also initiated the Phase 1 trial of HWK-206, marking the advancement of all three of our original ADC programs into clinical development within the last 12 months. With its improved biparatopic design, HWK-206 has demonstrated enhanced preclinical antitumor activity compared to other SEZ6-targeted ADCs. Our global clinical development strategy is focused on efficiently evaluating how these preclinical attributes translate in patients with small-cell lung cancer."
Q3 2026 and Recent Operational Highlights:
Continued to advance the ongoing Phase 1 trials of HWK-007 and HWK-016.
HWK-007, a PTK7-targeting ADC, is being evaluated in patients with non-squamous, EGFR wild-type non-small cell lung cancer; platinum-resistant ovarian cancer; and endometrial cancer (NCT07444814).
HWK-016, a MUC16-targeting ADC, is being evaluated in patients with advanced ovarian and endometrial cancers (NCT07470853).
Initiated the Phase 1 clinical trial of HWK-206 in the U.S. and received Fast Track designation from the U.S. Food and Drug Administration (FDA).
HWK-206 is a novel, biparatopic, SEZ6-targeting ADC utilizing the same TOP1i-linker payload as Whitehawk’s first two programs. HWK-206 is being developed initially for small-cell lung cancer (SCLC) and other neuroendocrine tumors.
Whitehawk submitted an Investigational New Drug (IND) application in China and anticipates activating its first clinical sites in China in Q1 2027.
The study is designed to evaluate an accelerated sequence of planned dose levels, starting at 3 mg/kg, informed by Whitehawk’s experience with HWK-007 and HWK-016. The initial dose-escalation portion will focus on patients with SCLC, providing an opportunity to evaluate HWK-206 against established clinical benchmarks.
Initial Phase 1 data from HWK-206 is expected by year-end 2027.
Presented real-world analyses supporting PTK7 as a durable ADC target in EGFR wild-type NSCLC at World Conference on Lung Cancer 2026. PTK7 expression remained stable following standard-of-care therapies, supporting its relevance as a target in second-line or later-line EGFR wild-type NSCLC.
Presented real-world analyses supporting MUC16 as a durable ADC target in ovarian cancer at International Gynecologic Cancer Society 2026. MUC16 expression remained high and stable following standard-of-care therapies, supporting its potential utility in both combination approaches and relapsed settings. High MUC16 expression was associated with poor real-world overall survival in high-grade serous ovarian carcinoma, the most common subtype of ovarian cancer.
Appointed Vijay Iyengar, MD, to Board of Directors. Dr. Iyengar, a former Incyte executive, brings extensive oncology, corporate strategy, business development and medical affairs experience to Whitehawk.
