ClinConnect Summary

This clinical trial is studying a new treatment approach for women with advanced or recurrent endometrial cancer, which is a type of cancer that occurs in the lining of the uterus. The researchers want to find out how effective a combination of two drugs, dostarlimab and carboplatin-paclitaxel, followed by treatment with dostarlimab alone, works in treating this condition. The trial is currently looking for female participants aged 65 to 74 who have been diagnosed with advanced endometrial cancer that has either come back after treatment or has not responded to other therapies.

To be eligible for this study, participants must have confirmed endometrial cancer that is either at Stage III or IV, or has come back after initial treatment with a low chance of being cured with surgery or radiation. They should also have a specific type of cancer determined by genetic testing. Women who are pregnant, breastfeeding, or have certain other health issues may not qualify. Participants can expect to receive the study drugs and be monitored closely for their health throughout the trial. This study offers a chance to contribute to the understanding of new treatment options for endometrial cancer, which could help improve outcomes for future patients.
