BioMedWire Editorial Coverage: Multiple sclerosis (“MS”) robs people of control over their own bodies — slowly, relentlessly and without a cure. More than 2.9 million people worldwide are living with MS today, and despite decades of research, every approved treatment falls short of the same fundamental goal: stopping the disease cold. Current therapies can slow progression, but they cannot halt it, and for millions of patients, that gap means a future of worsening disability. Now, Quantum BioPharma Ltd. (NASDAQ: QNTM) (CSE: QNTM) ( Profile ) is challenging that reality.

CAMBRIDGE, Mass. and SOUTH SAN FRANCISCO, Calif., May 21, 2026 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) and Denali Therapeutics Inc. (Nasdaq: DNLI) today announced topline results from the Phase 2b LUMA study evaluating BIIB122 (DNL151), an investigational small molecule inhibitor of LRRK2 (leucine-rich repeat kinase 2), in individuals with early-stage Parkinson’s disease. Results from the study show that BIIB122 did not slow the progression of Parkinson’s disease versus placebo, as measured by the primary endpoint of Time to Confirmed Worsening in the modified Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) Part II and III combined score. Secondary endpoints also did not show a benefit with BIIB122. Exploratory biomarker endpoints demonstrated >90% kinase inhibition of peripheral LRRK2 (phosphoserine 935) and, in a cerebrospinal fluid (CSF) sub-study, up to approximately 30% reduction observed in a biomarker of LRRK2 activity (phosphorylated Rab10). Expected levels of BIIB122 in the blood and CSF were sustained across the study. BIIB122 was generally well tolerated with an acceptable safety profile. Based on these results, Biogen and Denali will discontinue further development of BIIB122 in idiopathic Parkinson’s disease. Denali will continue to independently conduct the Phase 2a BEACON study evaluating the small molecule inhibitor in carriers of a pathogenic LRRK2 variant.

Levi, Esq. via email at jlevi@levikorsinsky.com or by telephone at (212) 363-7500.

CELIA did not meet its primary endpoint assessing dose response; based on the strength of the biomarker and efficacy data, Biogen plans to advance diranersen to registrational development
