Clemastine fumarate accelerates accumulation of disability in progressive multiple sclerosis by enhancing pyroptosis.

ABSTRACT: Multiple sclerosis (MS) is an immune-mediated demyelinating disease of the CNS. Clemastine fumarate, the over-the-counter antihistamine and muscarinic receptor blocker, has remyelinating potential in MS. A clemastine arm was added to an ongoing platform clinical trial, targeting residual activity by precision, biomarker-guided combination therapies of multiple sclerosis (TRAP-MS) (ClinicalTrials.gov NCT03109288), to identify a cerebrospinal fluid (CSF) remyelination signature and to collect safety data on clemastine in patients progressing independently of relapse activity (PIRA). The clemastine arm was stopped per protocol-defined criteria when 3 of 9 patients triggered individual safety stopping criteria. Clemastine-treated patients had significantly higher treatment-induced disability p
