DAXI's novel formulation, which includes a custom-engineered peptide, is designed to provide an extended duration of clinical benefit.</div></div><div><h3>Objective</h3><div>To evaluate the pooled efficacy and safety of DAXI for CD across two phase 3, multicenter, randomized, double-blind, placebo-controlled trials: ASPEN-1, conducted in North America and Europe, and ASPEN-1-CN, a similarly designed, smaller pivotal clinical trial, conducted in China.</div></div><div><h3>Methods</h3><div>Adults with moderate-to-severe CD were randomized (3:3:1) to receive DAXI 125U, DAXI 250U, or placebo. The primary endpoint was change from baseline in Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) total score averaged across weeks 4 and 6. A key secondary endpoint was duration, defined as time until loss of &gt;80 % of peak effect.</div></div><div><h3>Results</h3><div>In all, 357 subjects were randomized and received DAXI 125U (n = 149), DAXI 250U (n = 154), or placebo (n = 54). DAXI 125U (−12.0) and DAXI 250U (−11.9) significantly improved the mean TWSTRS total score versus placebo (−4.6; <em>P</em> &lt; 0.0001). Median (95 % CI) duration of effect was 24.1 (20.6–28.9) weeks for DAXI 125U and 22.0 (20.1–24.3) weeks for DAXI 250U. Rates of treatment-related dysphagia (125U: 4.7 %, 250U: 4.5 %) and muscle weakness (125U: 5.4 %, 250U: 4.5 %) were low for both active doses.</div></div><div><h3>Conclusions</h3><div>This pooled analysis of two phase 3 trials demonstrates that DAXI is an effective, safe, and long-acting treatment for CD. Key adverse events occurred at rates lower than prior pivotal trials of BoNTs for CD.</div></div>","PeriodicalId":19970,"journal":{"name":"Parkinsonism & related disorders","volume":"140 ","pages":"Article 108015"},"PeriodicalIF":3.4,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145080962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
