Several Asia biotechs this week – including Innocare Pharma Ltd., Akeso Pharmaceuticals Inc., Sanbio Co. Ltd. and Ascletis Pharma Inc. – unveiled the start of new late-stage clinical trials or interim findings from early stage studies.
Researchers from Tianjin University have published data regarding development and preclinical characterization of a new anti-PD-L1/CD40 bispecific antibody (BsAb), BA-4415, designed to activate CD40 signaling specifically in the context of PD-L1 while simultaneously blocking PD-1/PD-L1 signaling.
In autoimmune diseases such as inflammatory bowel disease (IBD), the function of regulatory CD8 T cells (CD8 Treg) is compromised, in part due to the expression of inhibitory KIR receptors (KIR2DL1/2/3) and insufficient inducible T-cell co-stimulator (ICOS) signaling. Mozart Therapeutics Inc. has discovered MTX-201, a new bispecific antibody targeting inhibitory KIR and ICOS that are co-expressed by CD8 Tregs.
Bambusa Therapeutics Inc. has completed an oversubscribed series A financing of approximately $90 million to support its lead programs through phase I trials and advance its pipeline of long-acting bispecific antibodies for immunological and inflammatory disorders.
Akeso Inc. has received IND approval by China’s National Medical Products Administration (NMPA) for AK-139, an IL-4Rα/ST2 bispecific antibody under investigation for a number of indications, including respiratory and skin diseases.
Intercellular communication between tumor cells and cancer-associated fibroblasts (CAFs) plays a key role in tumorigenesis and progression, and CAFs generate an extracellular matrix that provides a repository for factors that promote cancer progression. Alpha Beta Therapeutics Inc. researchers aimed to investigate the mechanisms by which CAFs facilitate tumor initiation and tumorigenesis of pancreatic cancer.
Kexing Biopharm Co. Ltd. has outlined progress in its cachexia and autoimmune pipelines, built upon its Kx-Body antibody technology platform and Kx-Fusion fusion protein technology platform.
In another Chinese newco out-licensing deal, Innocare Pharma Ltd. and Keymed Biosciences Co. Ltd. out-licensed their co-developed CD20×CD3 bispecific antibody (ICP-B02/CM355) to startup Prolium Bioscience Inc. in a deal worth up to $520 million.
Cancer immunotherapy has represented a significant advancement in cancer treatment; however, many patients experience relapse or develop resistance to this treatment. Bispecific antibodies that selectively engage T-cell costimulatory molecules have emerged as a novel therapeutic strategy to overcome the limitations of immunotherapy.
