Sanofi SA reported more hitches in the development of Bruton’s tyrosine kinase inhibitor tolebrutinib, saying the phase III Perseus study failed to meet its primary endpoint in primary progressive multiple sclerosis (MS) and that the ongoing U.S. regulatory review in non-relapsing secondary progressive MS likely will extend beyond the targeted PDUFA date of Dec. 28.

Arcus Biosciences Inc. and partner Gilead Sciences Inc. are scrapping phase III work with anti-TIGIT antibody domvanalimab after an independent data monitoring committee said the drug will fail in gastric and esophageal cancers.

Rezolute Inc.’s phase III Sunrize study of its only candidate, ersodetug, a fully human monoclonal antibody that binds to allosteric site on insulin receptors, missed its primary and secondary endpoints in treating the ultra-rare disease congenital hyperinsulinism.

AC Immune SA plans talks with regulators based on positive interim safety and efficacy results from the phase II Vacsyn trial of its wholly owned anti-alpha-synuclein (a-syn) active immunotherapy ACI-7104.056 in early Parkinson’s disease (PD). The firm said that for the first time, data support targeting a-syn pathology via such a strategy. Disease-related biomarker results that suggest PD slowing include a-syn cerebrospinal fluid (CSF) levels and neurofilament light (NfL).

Eli Lilly and Co.’s latest phase III results for the obesity and overweight populations suggest its triple agonist, retatrutide, can deliver significant weight loss that, in turn, leads to reduced osteoarthritis knee pain.

Novartis AG’s monoclonal antibody, ianalumab (VAY-736), when added to standard-of-care eltrombopag, extended disease control of primary immune thrombocytopenia (ITP) by 45%, according to data presented Dec. 9 during a late-breaker abstract session at the 67th American Society of Hematology’s annual meeting in Orlando, Fla.

Impressive results of a potential second-line combination treatment for multiple myeloma from the Majestec-3 trial of teclistamab plus daratumumab raised eyebrows at the American Society of Hematology’s 67th annual meeting, with the combination showing an 83.4% rate of progression-free survival at three years vs. 29.7% for standard of care.

With new results from Wave Life Sciences Ltd., Structure Therapeutics Inc. and Ascletis Pharma Inc., obesity management drugs continue to move forward in producing weight loss and move the market.

Targeted therapies and immunotherapies continue to show better results than chemotherapy in investigator-initiated and company-sponsored cancer trials, and newer options demonstrate improvements over older ones, supporting potential shifts in how patients are treated.
