Effective vaccines against Staphylococcus aureus remain out of reach: 10 candidates that showed promise in preclinical animal models have failed in clinical trials. Researchers at Third Military Medical University and collaborators reasoned that one of the reasons might be that 70%-80% of the population has developed antibodies to the pathogen.

Bio-Thera Solutions Inc. announced Aug. 26 that the European Commission cleared Usymro (BAT-2206) as a biosimilar to Janssen Pharmaceuticals Inc.’s Stelara (ustekinumab). The EMA issued marketing authorization for Usymro on Aug. 14, following the EMA’s Committee for Medicinal Products for Human Use adopting a positive opinion on June 19.

Akeso Pharmaceuticals Inc.’s gumokimab (AK-111) and manfidokimab met all primary efficacy endpoints in its phase III trials in active ankylosing spondylitis and in moderate to severe atopic dermatitis, respectively.

Novartis AG’s monoclonal antibody, ianalumab, has notched back-to-back wins, one in treating Sjögren’s disease and the other for primary immune thrombocytopenia (ITP).  In Sjögren’s, which has no U.S. FDA-approved treatment, the phase III Neptunus-1 and Neptunus-2 studies are the first phase III trials to prompt statically significant reductions in adults with the autoimmune disease. In ITP, a disease that has yet to see a cure, top-line data of a phase III study of ianalumab combined with eltrombopag stretched to the time to treatment failure compared to placebo, the primary endpoint showing the maintenance of safe platelet levels.

A month away from the PDUFA decision date for a Leqembi (lecanemab) subcutaneous autoinjector to be used for maintenance dosing for those with early Alzheimer’s disease, Eisai Co. Ltd. and Biogen Inc. presented clinical data at the Alzheimer's Association International Conference (AAIC) 2025 in Toronto, showing comparable efficacy and safety to the FDA-approved intravenous formulation.

Radiopharm Theranostics Ltd. announced that the U.S. FDA has cleared the IND application for betabart (RV-01), its Lu177-B7H3 monoclonal antibody designed with strong affinity for the 4Ig isoform of B7-H3 that is highly expressed in tumors and not in healthy tissues.

Formation Bio Inc. has licensed worldwide rights to Imidomics Inc.’s potentially first-in-class anti-CD226 monoclonal antibody (mAb). The program has received IND clearance and will be advanced by Formation Bio in autoimmune indications, starting with ulcerative colitis.

Intracerebral hemorrhage accounts for 10%-15% of all cases of stroke, and it is associated with particularly poor prognosis due to primary and secondary brain injury driven by neuroinflammation. This inflammation involves the activation and subsequent pyroptosis, or lytic cell death, of microglia.
