Biogen to Advance Investigational Spinal Muscular Atrophy Asset to Registrational Studies Based on Positive Interim Phase 1 Results
CAMBRIDGE, Mass., June 25, 2025 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) announced topline results from the Phase 1 study of salanersen (BIIB115/ION306), an antisense oligonucleotide (ASO) being developed for the treatment of spinal muscular atrophy (SMA). Leveraging the same mechanism of action as SPINRAZA (nusinersen) but designed to achieve greater potency, salanersen has the potential to achieve high efficacy and enable once yearly dosing. An interim analysis of the Phase 1 study in participants with SMA who were previously treated with gene therapy was conducted to inform the decision on whether to move salanersen forward into registrational studies. Both dose levels tested, 40 mg and 80 mg, given once a year, were generally well-tolerated and led to substantial slowing of neurodegeneration, as shown by reductions in neurofilament. Exploratory clinical outcome data shows clinically meaningful improvements in function and attainment of new World Health Organization (WHO) milestones over 1 year. These data will be presented today at the SMA Research & Clinical Care Meeting hosted by Cure SMA in Anaheim, Calif.

BRUSSELS and CAMBRIDGE, Mass., June 12, 2025 (GLOBE NEWSWIRE) -- UCB (Euronext Brussels: UCB) and Biogen Inc. (NASDAQ: BIIB) today presented additional detailed results from the Phase 3 PHOENYCS GO study evaluating dapirolizumab pegol (DZP), a novel Fc-free anti-CD40L drug candidate.
