In the skin adhesion trial in 43 randomized PD patients, the cumulative mean percentage of adhesion (90% CI) at the end-of-dosing interval was 92.948% (90.156 - 95.740%) for ROT-TDS and 90.471% (87.574 - 93.367%) for the reference. For ROT-TDS, 80.23% of patches were ≥ 90% adhered at the end-of-dosing interval, while this was the case for 67.44% of the reference patches. Safety and skin tolerability of both products were comparable; the most frequent treatment-related adverse event was application-site pruritus for both treatments at comparable extent.</p><p><strong>Conclusion: </strong>ROT-TDS - with shown BE to the originator reference product - displayed similar safety and local tolerability as the reference product in patients with PD. The results show a trend to improved skin adhesion of the new patch compared to the reference in the target population.</p>","PeriodicalId":13963,"journal":{"name":"International journal of clinical pharmacology and therapeutics","volume":" ","pages":"77-86"},"PeriodicalIF":0.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142380789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
