Dostarlimab was approved for treating adult patients with mismatch repair deficient (dMMR) recurrent or advanced endometrial cancer (EC) that progressed during or after prior treatment who have no other suitable treatment options. Herein, we review the structure-based mechanism of action of dostarlimab and the results of a clinical study (GARNET; NCT02715284) to comprehensively clarify the efficacy and toxicity of the drug. The efficacy and safety of dostarlimab as monotherapy was assessed in a non-randomized, multicenter, open-label, multi-cohort trial that included 209 patients with dMMR recurrent or advanced solid tumors after receiving systemic therapy. Patients received 500 mg of dostarlimab intravenously every three weeks until they were given four doses. Then, patients received 1000 mg dostarlimab intravenously every six weeks until disease progression or unacceptable toxicity. The overall response rate, as determined by shrinkage in tumor size, was 41.6% (95% confidence interval [CI]; 34.9, 48.6), with 34.7 months as the median response duration. In conclusion, dostarlimab is an immunotherapy-based drug that has shown promising results in adult patients with recurrent or advanced dMMR EC. However, its efficacy in other cancer subtypes, the development of resistance to monotherapy, and efficacy and safety in combination with other immunotherapeutic drugs have not yet been studied.</p></div>","PeriodicalId":93920,"journal":{"name":"Cancer pathogenesis and therapy","volume":"2 3","pages":"Pages 135-141"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S294971322300085X/pdfft?md5=da6c271bd6c1eecc55a01fce646df3ba&pid=1-s2.0-S294971322300085X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135852344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
