We assessed the safety, efficacy, and CSF drug concentrations of fenebrutinib, a highly selective, noncovalent, reversible BTK inhibitor, in patients with relapsing multiple sclerosis.<h3>Methods</h3>This multicentre, double-blind, randomised, placebo-controlled, phase 2 trial (FENopta) was conducted at 18 community centres and hospitals across six countries in Europe and North America. Patients with relapsing multiple sclerosis aged 18–55 years with an Expanded Disability Status Scale (EDSS) score of 0·0–5·5, and recent documented disease activity, were randomly assigned (2:1) to oral fenebrutinib (200 mg twice daily) or placebo for 12 weeks, using permuted blocks and stratified by the presence or absence of T1 gadolinium-enhancing (Gd+) lesions on the brain MRI at screening. The randomisation sequence was generated by an interactive voice or web response system and both patients and investigators were masked to treatment allocation. Participants could enter an optional open-label extension study to receive fenebrutinib for up to 192 weeks. The primary efficacy endpoint was the total number of new T1 Gd+ lesions on brain MRI at weeks 4, 8, and 12; with additional MRI assessments at 48-week intervals during the open-label extension. Efficacy analyses were done on randomised patients with evaluable post-baseline MRIs; safety analyses used the safety-evaluable population.

Through the agnostic screening of children with acute axonal neuropathy after an infection, we identified several families with biallelic variants in <em>RCC1</em>. We aimed to describe the clinical phenotype of these patients, and the molecular and cellular pathology associated with the genetic variants identified in these families.<h3>Methods</h3>For this case series, we identified children affected by a severe, acute-onset axonal neuropathy following infection through an international research consortium of paediatric neurologists and clinical geneticists from nine countries (Canada, Cyprus, Czechia, Germany, Iran, Saudi Arabia, Slovakia, Türkiye, and the UK). Clinical assessments included nerve conduction studies and neuroimaging. We did exome or genome sequencing in DNA samples from all patients. We characterised the proteins encoded by the genetic variants by use of thermal stability and enzymatic assays, using recombinantly expressed proteins. We assessed cellular protein transport under heat or oxidative stress by use of immunofluorescence in primary fibroblasts, obtained from patients. We generated a humanised <em>Drosophila</em> knock-in model to assess the effects of stress on the in vivo function of RCC1.<h3>Findings</h3>Between Nov 2, 2011, and July 10, 2024, we identified 24 individuals from 12 families who had severe, acute-onset axonal neuropathy following infection (13 female and 11 male patients, with a mean age at diagnosis of 1 year 10 months [SD 2·27]). Eight biallelic missense variants in <em>RCC1</em> were identified in affected individuals with autosomal recessive inheritance. Patients had variable phenotypes, ranging from rapidly progressive fatal axonal neuropathy to mild motor neuropathy with impaired walking. Neurological presentation was often secondary to an infection, resulting in initial misdiagnoses of Guillain-Barré syndrome in several patients. 15 children had disease recurrence. The disease was fatal in 15 patients. The <em>RCC1</em> variants in these patients code for proteins that alter GDP-to-GTP exchange activity and have reduced thermal stability in vitro. In primary fibroblasts, heat shock or oxidative stress revealed defects in Ran nuclear localisation and impaired nucleocytoplasmic transport. A <em>Drosophila</em> model of the disease revealed a fatal intolerance to oxidative stress.<h3>Interpretation</h3>We describe an autosomal recessive, acute-onset paediatric axonal neuropathy, seemingly triggered by infection, that affects individuals with biallelic <em>RCC1</em> variants. In these children, the disease can mimic Guillain-Barré syndrome. The pathological mechanisms underlying this novel axonal neuropathy might overlap with those of amyotrophic lateral sclerosis. Cellular studies indicate that <em>RCC1</em> variants affect nucleocytoplasmic transport, which is crucial for healthy axonal f","PeriodicalId":22676,"journal":{"name":"The Lancet Neurology","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144645269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
