MediciNova Activates SEANOBI Study with 100 Patient Enrollments
- Patient Enrollment Progress: As of the end of January 2026, MediciNova has successfully enrolled 100 ALS patients across 12 sites in the U.S., achieving 50% of the planned 200 enrollments, marking significant progress in the clinical development of MN-166 and potentially accelerating the drug approval process.
- Funding Support: The SEANOBI Expanded Access Program is backed by a $22 million NINDS grant, designed to provide MN-166 treatment access to ALS patients not eligible for ongoing randomized trials while collecting crucial clinical and biomarker data, enhancing the drug's market competitiveness.
- Clinical Trial Design: MN-166 is also undergoing the COMBAT-ALS Phase 2b/3 randomized controlled trial, with 234 patients enrolled in the U.S. and Canada, and top-line results expected by the end of 2026, which will provide essential evidence for the drug's future approval.
- Strategic Implications: MediciNova's MN-166 has received Orphan Drug Designation from the FDA and EMA, along with Fast Track Designation from the FDA, and the combined clinical data from SEANOBI and COMBAT-ALS will offer more treatment options for ALS patients, addressing the urgent market demand for new therapies.
