Novartis reports strong Phase III results for BTK inhibitor remibrutinib in relapsing MS

Novartis announced that its oral BTK inhibitor remibrutinib cut the annualized relapse rate by 35.2% in one Phase III trial and 31.2% in a second trial versus teriflunomide. The drug also lowered the risk of 6‑month confirmed disability progression by 29.2% and showed no liver safety signal. Results were presented at the MSToronto2026 conference and published in The Lancet, and the company said it will seek global regulatory approval.

The data give Novartis a potential new therapy in the large relapsing‑multiple‑sclerosis market, creating a future revenue catalyst if regulators approve the drug. The favorable safety profile may aid payer acceptance and market uptake.
