Novel Patented Myelin Drug-Discovery Strategy Targets Massive Unmet Need in Multiple Sclerosis
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. The company is advancing Lucid-MS, a patented, first-in-class drug candidate that takes a fundamentally different approach by directly targeting the myelin sheath that MS destroys, and this new drug candidate is preparing to enter phase 2 clinical trials. Quantum BioPharma is one of several companies focused on the development and commercialization of therapies for neurological, autoimmune and immune-mediated diseases, including Sanofi (NASDAQ: SNY), Roche Holding AG (OTCQX: RHHBY), Biogen Inc. (NASDAQ: BIIB) and…

Biogen and Denali Therapeutics Provide Update on Phase 2b LUMA Study of BIIB122 (DNL151) in Early-Stage Parkinson’s Disease
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.
