Sanofi’s Cenrifki (tolebrutinib) recommended for EU approval by the CHMP to treat secondary progressive multiple sclerosis without relapses
- Recommendation based on the HERCULES phase 3 study which demonstrated that brain-penetrant Cenrifki (tolebrutinib) significantly delayed the onset of disability progression in non-relapsing SPMS
Paris, April 24, 2026. The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion recommending the approval of Cenrifki (tolebrutinib) in the EU for the treatment of secondary progressive multiple sclerosis (SPMS) without relapses in the last two years. A final decision is expected in the coming months.
SPMS is a debilitating stage of multiple sclerosis where patients experience continuous accumulation of disability, including fatigue, cognitive impairment, mobility difficulties, and loss of independence – often without available treatment options. Addressing disability progression remains one of the most significant unmet needs in MS care.
The positive CHMP opinion is based on data from the HERCULES phase 3 study (clinical study identifier: NCT04411641) in non-relapsing SPMS, with supporting data from the GEMINI 1 (clinical study identifier: NCT04410978) and GEMINI 2 (clinical study identifier: NCT04410991) phase 3 studies in relapsing multiple sclerosis (RMS), which were presented at the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) Conference 2024, the American Academy of Neurology (AAN) 2025 Annual Meeting, and published in The New England Journal of Medicine. The safety profile of Cenrifki has been consistent across the clinical program. Most common adverse events were COVID-19 and upper respiratory tract infections. Significant liver enzyme elevations were also observed. Drug-induced liver injury (DILI) is an identified safety risk of tolebrutinib. Strict adherence to liver monitoring requirements, and prompt management of liver enzyme elevations, are important to mitigate DILI risk.
Additional submissions for Cenrifki are currently under review with regulatory authorities worldwide.
