The intriguing VEGFxPD-1 bispecific antibody space gained oomph with phase III results disclosed April 23 by Akeso Pharmaceuticals Inc. related to Harmoni-6, testing ivonescimab in combination with platinum-based chemotherapy compared with Tevimbra (tislelizumab, Beigene Ltd.), a PD-1 inhibitor also paired with platinum-based chemo in patients with locally advanced or metastatic squamous non-small-cell lung cancer irrespective of PD-L1 expression. Those data were followed by a green light from the U.S. FDA April 24 for marketing the PD-1 monoclonal antibody penpulimab in combination with cisplatin or carboplatin and gemcitabine for the first-line treatment of adult recurrent or metastatic non-keratinizing nasopharyngeal carcinoma.
Tharimmune Inc. has announced preclinical data from its expanded pipeline with HS-1940, a dual-target multispecific biologic engineered to bind to both programmed cell death protein 1 (PD-1) and vascular endothelial growth factor (VEGF), and HS-3215, a dual-target biologic binding to HER2 and HER3 receptors. Both use the proprietary Epiclick technology, a multispecific antibody engineering platform.
The U.S. FDA rejected, for the second time, Elevar Therapeutics Inc.’s NDA of a novel combination therapy for advanced liver cancer, which comprised Jiangsu Hengrui Pharmaceutical Co. Ltd.’s PD-1 inhibitor camrelizumab and HLB Co. Ltd.’s small-molecule tyrosine kinase inhibitor, rivoceranib.

Resident immune cells, including type 2 innate lymphoid cells (ILC2s), play a key role in adipose tissue homeostasis. Researchers from Sungkyunkwan University and affiliated organizations evaluated the impact of ILC2s on systemic metabolic regulation in obesity.
Shares of Phio Pharmaceuticals Corp. soared 291% Jan. 13 on news that two patients with cutaneous squamous cell carcinoma had a complete response following treatment with the company’s Intasyl siRNA gene silencing candidate PH-762.
The PD-1 receptor, a major immune checkpoint inhibitor whose signaling is the target of multiple blockbuster anticancer drugs, differs functionally between rodents and humans in previously unknown ways. Researchers from the University of California, San Diego, and co-authors at the Chinese Academy of Sciences and the National Cancer Institute reported these findings in the Jan. 3, 2025, online issue of Science Immunology.
Seismic Therapeutic Inc. has provided preclinical data for S-4321, a novel dual-cell bidirectional (DcB) PD-1:FcγRIIb antibody being developed for the treatment of autoimmune disease.
The use of interleukin-2 (IL-2)-directed therapies has been associated with systemic toxicities, regulatory T cell (Treg) activation and limited efficacy so far. Researchers from Regeneron Pharmaceuticals Inc. have described REGN-10597 (PD1-IL2Ra-IL2), a programmed cell death protein 1 (PD-1)-targeted, receptor-masked IL-2 immunocytokine.
With another failure of E-selectin antagonist uproleselan on the books, Glycomimetics Inc. signed an acquisition agreement with privately held, solid tumor-focused Crescent Biopharma Inc., and a syndicate of investors has put up $200 million to make the merger possible.
