Tonix Pharmaceuticals Holding Corp. has entered into a sponsored research agreement with Boston Children's Hospital to study TNX-1500, an Fc-modified anti-CD40L monoclonal antibody, for the prevention of graft-vs.-host disease (GVHD) after hematopoietic stem cell transplant (HSCT) in animals.
Mast cells (MCs) are tissue-resident immune cells and are responsible for allergic and inflammatory processes. One potential approach for targeting MCs is to engage inhibitory receptors that can silence MC activation, such as sialic acid-binding immunoglobulin-like lectins (siglecs). Siglec-6 is an inhibitory receptor expressed on human MCs and represents an attractive therapeutic target for this purpose. Siglec-6 engagement with a monoclonal antibody (MAb) was recently shown to inhibit MC activation in vitro.
Exelixis Inc. and Sairopa BV have entered into an exclusive clinical development and option agreement for ADU-1805, a potentially best-in-class monoclonal antibody that targets SIRPα.
China's National Medical Products Administration (NMPA) has cleared an IND application for a clinical trial of Shanghai Henlius Biotech Inc.'s HLX-60 for the treatment of solid tumors and lymphomas.
Endpoint Health Inc. has announced a new precision immunology program targeting inflammation mediated by tissue factor (TF)-dependent intracellular signaling.
Aqualung Therapeutics Corp. has been awarded two 3-year National Institutes of Health (NIH) Fast Track awards to support development of ALT-100 (enamptcumab), a humanized monoclonal antibody therapy for the chronic indications of pulmonary arterial hypertension (PAH) and inflammatory bowel disease (IBD).
What was once effective is now a non-starter. Newly updated guidelines from the World Health Organization (WHO) caution against using the COVID-19 treatments sotrovimab, from GSK plc and Vir Biotechnology Inc., and Regen-Cov (casirivimab + imdevimab), from Regeneron Pharmaceuticals Inc. Omicron, the group said, has rendered the monoclonal antibodies ineffective.
