Head of Global Clinical Development in Neurology at EMD Serono discussed the findings of a phase 2 assessment of the company’s investigational BTK inhibitor evobrutinib in multiple sclerosis.
“We are very excited because we know the drug works on B cells, which have been shown to have a central role in progression in MS, and on macrophages. This creates an avenue for us because we have a small-molecule drug that is an irreversible and highly selective inhibitor of BTK [which] plays a very essential role in the inflammatory potential of both.”
Phase 2 data presented at the 2020 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC 2020) suggest that the efficacy and safety of 75-mg evobrutinib, an investigational, oral, highly selective Bruton's Tyrosine Kinase (BTK) inhibitor, is maintained over the long-term in the treatment of patients with relapsing multiple sclerosis (MS).1
Those who received EMD Serono’s agent had an annualized relapse rate (ARR) of 0.11 (95% CI, 0.04—0.25) at Week 48, and 0.12 (95% CI, 0.06–0.22) for the full 108-week period. Evobrutinib was also considered generally well-tolerated, maintaining its known safety profile during the open-label extension period, with transient elevated liver aminotransferases, which was reported in the 48-week double-blind period, not observed in the extension.2
The phase 2 randomized controlled trial (NCT02975349) included 213 patients (79.8% of the 267 randomized) who were treated for 108 weeks, which consisted of the 48-week main study and 60-week open-label extension.
