Subpopulation of senescent-like cells are known contributors to acquiring drug resistance in cancer. Potential therapies are increasingly being developed with designs to reduce the proportion of slowly dividing cells rather than to kill hyperproliferative cells. Insufficient RNA-binding protein HuR/ELAVL1 levels are known to cause cell senescence, while increased HuR is associated with proliferation.
Researchers from Elpiscience Biopharma Ltd. have reported the construction of a PD-L1/SIRPα bispecific macrophage engager (BiME), ES-019. A panel of anti-PD-L1/SIRPα antibodies based on single domain antibody was generated, with the candidates containing different orientations, ratios and IgG isotypes of anti-PD-L1 arm and anti-SIRPα arm.
Immunocytokines (ICs) engage multiple mechanisms of action by the use of antibodies to deliver cytokine payloads to the surface of the same immune cell, known as cis-signaling. Researchers from Bright Peak Therapeutics AG have developed ICs by using a novel approach based on site-specific chemical conjugation of engineered cytokines to existing nonmodified antibodies.
Heat-shock protein 90 (HSP90) is known to be a key member of the epichaperome complex that is involved in the maintenance of protein homeostasis during stressful and nonstress conditions, and known to be overexpressed in glioma tumors, conferring cancer cells survival and resistance to therapy. In this study, researchers at The University of Texas MD Anderson Cancer Center investigated the activity and toxicity profile of MPT-0B640, an HSP90 inhibitor, for treating gliomas and its ability to cross the blood-brain barrier (BBB) using glioma stem-like cell (GSC) lines.
As GSK plc pulls Blenrep (belantamab mafodotin) from the U.S. market, the biotech giant will watch a lot of revenue go with it. Only two weeks ago a phase III confirmatory study data for the already-approved multiple myeloma drug fell short of meeting requirements for the U.S. FDA’s accelerated approval regulations, so the agency asked GSK to take the drug off the market.
Global interest in radiopharmaceuticals is growing, and some big deals in the space have sparked interest in the last few years. Novartis AG has spent about $6 billion in acquisitions and is seen as the global leader.
Biotheus Inc. out-licensed Chinese rights to its preclinical EGFR/MET bispecific antibody, PM-1080, to Hansoh Pharmaceutical Group Co. Ltd. for ¥50 million (US$359,150) up front and up to ¥1.42 billion in future development, regulatory and commercialization milestones, plus tiered sales-based royalties.
Shanghai Junshi Biosciences Co. Ltd. has submitted a new drug application (NDA) for its anti-PD-1 monoclonal antibody toripalimab to the European Medicines Agency, which marks the first NDA filing of toripalimab in Europe.
Astellas Pharma Inc.’s zolbetuximab, a monoclonal antibody targeting Claudin 18.2, met the primary endpoint of progression-free survival in the phase III Spotlight trial in CLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma, according to top-line data.
