Sanofi Says It Will Not Pursue Regulatory Registration For PPMS
Sanofi announced it will not pursue regulatory registration for its drug, Tolebrutinib, in treating Primary Progressive Multiple Sclerosis (PPMS) after failing to meet primary endpoints. PPMS accounts for 10% of MS patients. Sanofi will conduct an impairment test on Tolebrutinib's intangible asset value, with results expected in January 2026. This decision will not affect business net income or EPS, nor change financial guidance for 2025.
