About this study

The main goal of this clinical trial is to evaluate dostarlimab, an immunotherapy drug, as a potential alternative to surgery for early-stage endometrial cancer with Mismatch Repair deficiency, a genetic cause for 20-30% of cases. The study aims to establish dostarlimab's efficacy and safety in early-stage endometrial cancer, exploring its potential as a non surgical option for those unsuitable or unwilling to undergo major surgery, allowing for fertility preservation or addressing specific health conditions. Participants will have seven dostarlimab sessions over 12 months. The treatment plan involves four cycles every three weeks, followed by a three-week break, and then three cycles every six weeks. This research is a promising step toward a new, less invasive treatment choice for patients with specific genetic traits. It expands the range of care options for endometrial cancer.
