Supportive care measures used to manage symptoms of toxicity are associated with extended hospital length of stay, high cost of care, and poor survival.

Treatment of each additional patient with uridine triacetate was associated with an incremental cost of US$25,247 per patient. Seventy percent of the drug cost was offset by reduction in inpatient healthcare resources utilization.

Forced vital capacity trends were consistent with ALSFRS-R.</p><p><strong>Conclusions: </strong>This study supports the safety, tolerability and extended half-life of NUN-004, and provides preliminary evidence for its ability to ameliorate disease progression in an amyotrophic lateral sclerosis cohort.</p><p><strong>Clinical trial registration: </strong>Registered on ANZCTR under identifier ACTRN12621000514808 (3 May, 2021).</p>","PeriodicalId":10402,"journal":{"name":"Clinical Drug Investigation","volume":" ","pages":"17-28"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142766822","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}
