Intriguing scientific data continue to roll out in the head and neck cancer space, where the need for therapies has spurred a number of drug firms to try new approaches, which BioWorld examines in part two of a series that began in the Dec. 30 issue.
In a deal worth up to $1 billion, Ideaya Biosciences Inc. is in-licensing Jiangsu Hengrui Pharmaceuticals Co. Ltd.’s SHR-4849, a phase I DLL3-targeting opo-I-payload antibody-drug conjugate (ADC). Under terms of the deal, San Francisco-based Ideaya will develop and commercialize SHR-4849 worldwide outside of greater China, and Shanghai-based Hengrui is eligible to receive up to $1.04 billion that includes a $75 million up-front fee, $200 million in development and regulatory milestone payments, and commercial success-based milestone payments. Hengrui is also eligible to receive royalties on net sales outside of greater China.
From local drug discovery to global innovation, economic uncertainty is taking a toll on China’s innovative biotech system, forcing local companies to weather unpredictable storms, investors said during the Chinabio Partnering Forum in Shanghai in September.
Daiichi Sankyo Co. Ltd.’s trophoblast cell surface antigen 2 (Trop2)-directed antibody-drug conjugate (ADC), datopotamab deruxtecan (dato-dxd), has been approved in Japan for treating adults with hormone receptor (HR)-positive, HER2-negative unresectable or recurrent breast cancer after prior chemotherapy.
Among the most profound results presented at the 2024 European Society for Medical Oncology Congress were the 10-year data from the Checkmate-067 and Keynote-006 trials of Opdivo and Keytruda as first-line agents in advanced or metastatic melanoma in which 10-year overall survival topped 40%. The success of checkpoint blockade, however, has not extended to all tumor types, but in 2024, molecular studies have led to advances in gene therapies and a multitude of approaches that have opened the door to hope.
Unogen Biotech Ltd. has identified triple inhibitors of EGFR (HER1; erbB1), ALK tyrosine kinase receptor and hepatocyte growth factor receptor (HGFR; MET) reported to be useful for the treatment of (non-small-cell) lung cancer.
Suzhou Puhe Biopharma Co. Ltd. has disclosed histone deacetylase 1 (HDAC1) inhibitors acting as REST Corepressor 1 (RCOR1; CoREST)/histone deacetylase (HDAC) complex inhibitors reported to be useful for the treatment of cancer.
Though Pyxis Oncology Inc.’s preliminary phase I data with antibody-drug conjugate (ADC) PYX-201 in solid tumors were characterized as positive, findings sent the Boston-based firm’s stock (NASDAQ:PYXS) into a tailspin. Shares dropped from $3.82 to $2.01 between Nov. 20 and the morning of Nov. 21, even as experts along with Wall Street agreed that the compound shows particular promise in head and neck squamous cell carcinoma – a space where developers aplenty remain busy.
