Whitehawk Therapeutics entered into a new option agreement with Hangzhou DAC for access to CPT113 for use in up to five additional antibody drug conjugate, or ADC, programs. Whitehawk's ADC platform leverages CPT113 as the core linker-payload technology, adding its own proprietary Carbon Bridge Cysteine Re-pairing, or CBCR, bioconjugation process to support improved stability and therapeutic index. Whitehawk will select targets and source antibodies, while retaining global rights and full program control for the new ADC programs. Whitehawk anticipates submitting Investigational New Drug applications for multiple new programs over the next 12-24 months. Hangzhou DAC's DXC006 is a CD56-directed ADC that utilizes CPT113. DXC006 is being evaluated in first-in-human Phase 1 dose escalation/expansion study in China in solid tumor populations. Data from DXC006 were accepted for oral presentation at the American Society of Clinical Oncology Annual Meeting. The abstract points to clinical activity and a favorable safety profile characterized by an absence of key safety concerns typically associated with a Top1i class. Phase 1 trials for PTK7-directed HWK-007 and MUC16-directed HWK-016 are advancing through dose-escalation, with data expected in the first half of 2027.

About WHWK
Whitehawk Therapeutics, Inc., formerly Aadi Bioscience, Inc., is a preclinical stage oncology therapeutics company applying advanced technologies to established tumor biology to efficiently deliver improved cancer treatments. Its advanced three-asset antibody drug conjugate (ADC) portfolio is engineered to overcome the limitations of first-generation predecessors to deliver a meaningful impact for patients with difficult-to-treat cancers. Its assets include HWK-007, HWK-016 and HWK-206. HWK-007 represents a differentiated opportunity to potentially be among the first next-wave ADCs in clinical development for high PTK7-expressing cancers. HWK-016 is the first ADC that targets the membrane-bound portion of MUC16, a glycoprotein often overexpressed in cancers of female origin. HWK-016 is being evaluated in IND-enabling studies. HWK-206 is designed to address the neuronal target, SEZ6, which is often overexpressed in cancers of neuroendocrine origin.

Whitehawk Develops Next-Gen ADC for Small Cell Lung Cancer
- SEZ6 Expression Advantage: SEZ6 expression in small cell lung cancer (SCLC) exceeds that of other approved and emerging ADC targets, indicating its clinical potential as an ADC target and offering new treatment options for patients.
- Dual Epitope Binding Technology: HWK-206 utilizes a biparatopic approach, suggesting potential advantages in binding and internalization, with preclinical models indicating its performance may surpass other single epitope ADCs, potentially enhancing therapeutic efficacy.
- IND Application Plans: An Investigational New Drug application for HWK-206 is expected to be submitted in mid-2026, with a Phase 1 trial planned to start in Q3 2026, marking a significant advancement in the development of treatments for SCLC and neuroendocrine tumors.
- Clinical Data Support: The findings will be presented at the 2026 American Society of Clinical Oncology Annual Meeting, further reinforcing SEZ6's clinical significance as an ADC target and potentially boosting HWK-206's market prospects.
