Effective vaccines against Staphylococcus aureus remain out of reach: 10 candidates that showed promise in preclinical animal models have failed in clinical trials.

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.
