MORRISTOWN, N.J., March 18, 2025 /PRNewswire/ -- Whitehawk Therapeutics, Inc. (Nasdaq: WHWK), formerly known as Aadi Bioscience, Inc., an oncology therapeutics company applying advanced technologies to established tumor biology to efficiently deliver improved cancer treatments, today announced it changed its name to Whitehawk Therapeutics, reflecting the Company's evolution and focus on accelerating its portfolio of antibody drug conjugates (ADCs) with speed, agility and precision. The Company's common stock will begin trading under the ticker "WHWK" effective March 19, 2025.

The three assets in the portfolio are in-licensed from WuXi Biologics and utilize HANGZHOU DAC's advanced ADC technology platform, which consists of a highly stable yet cleavable linker that delivers a Topoisomerase I (TOPO1) inhibitor payload. The platform is coupled with clinically validated tumor targets that are upregulated in high-potential cancer indications, including lung and ovarian. These assets are engineered to produce minimal off-target toxicity, with a higher therapeutic index and greater stability than first-generation predecessors.

"Today marks a transformative moment as we reintroduce ourselves as Whitehawk Therapeutics – a focused oncology company combining science, strategy and execution to swiftly advance our portfolio of promising ADC assets," said David Lennon, President and CEO, Whitehawk Therapeutics. "By leveraging the foundation of well-established tumor biology and integrating cutting-edge technologies, our strategy is designed to address the challenges of treating the most difficult cancers efficiently and effectively. Our goal is to bring all three assets to IND in the next 15 months. Importantly, we believe our robust balance sheet will enable us to see these three assets through early clinical inflections. We are invigorated by the opportunity we have to overcome the limitations of first-generation ADCs to make a meaningful impact for patients."

Recent Operational Highlights:

• All proposals were approved at the Company's Special Meeting of Stockholders on February 28, 2025. Subsequently, the $100 million PIPE financing closed. The closing of the divestiture of Aadi Subsidiary, Inc. ("Aadi Sub") to Kaken Pharmaceuticals ("Kaken") is pending.
  
  
• Aadi Bioscience divided into two organizations. Upon the divestiture of Aadi Sub to Kaken, Kaken will assume ownership of Aadi Sub, including the Aadi name, trademark and the FYARRO^® business. As of March 18, 2025, the Aadi parent company has become Whitehawk Therapeutics, with a focus on its portfolio of ADC assets.

Fourth Quarter and Full-year 2024 Financial Results:

• Cash, cash equivalents and short-term investments as of December 31, 2024, were $47.2 million as compared to $108.8 million as of December 31, 2023.
  
  
• Following closing of the strategic transactions, we expect to have cash and cash equivalents in the range of $170 million to $180 million, including the payment of the upfront and early milestones under the Wuxi ADC agreement.
  
  
• Total revenue for the quarter ended December 31, 2024, was $7.2 million, and $26.0 million for the full-year ended December 31, 2024, resulting from sales of FYARRO.
  
  
• Net loss for the three months ended December 31, 2024, was $18.3 million as compared to $16.3 million for the three months ended December 31, 2023. Net loss for the full-year ended December 31, 2024, was $63.7 million, as compared to $65.8 million for the same period in 2023.

About the ADC Portfolio

• HWK-007 represents a differentiated opportunity to potentially be among the first next-wave ADCs in clinical development for high PTK7 expressing cancers. HWK-007 is being evaluated in IND-enabling studies. The Phase 1 trial is planned in non-small cell lung cancer and platinum resistant ovarian cancer, with potential to expand into novel indications (e.g. gastrointestinal, gynecological).
  
  
• 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 currently being evaluated in IND-enabling studies. The Phase 1 trial is planned in ovarian cancer, with potential to expand into additional indications (e.g. endometrial, cervical).
  
  
• HWK-206 is designed to address the neuronal target, SEZ6, which is often overexpressed in cancers of neuroendocrine origin. HWK-206 utilizes a dual epitope binding, or biparatopic, approach which can potentially improve internalization and effectiveness of the ADC. HWK-206 is currently in candidate selection. The Phase 1 trial is planned in small-cell lung cancer and neuroendocrine neoplasms, where there are limited treatment options.
