Summary

This trial will test the effectiveness of a combination of all-trans retinoic acid (ATRA) and Cemiplimab in patients with advanced leiomyosarcoma who have not responded to

Who is the study for?

This trial is for patients with advanced leiomyosarcoma, a type of sarcoma, who have not responded to standard treatments. Participants must have metastatic or locally advanced disease that cannot be surgically removed.

What is being tested?

The study tests the combination of all-trans retinoic acid (ATRA) taken orally and Cemiplimab given intravenously in cycles. The effectiveness will be measured using imaging techniques like CT and MRI scans following a specific study design called BOP2.

What are the potential side effects?

Possible side effects include skin reactions, fatigue, immune-related issues such as inflammation in organs due to Cemiplimab, and headaches or bone pain from ATRA. Side effects vary by individual.

Experimental Treatment

Group I: Treatment (all-trans retinoic acid [ATRA] and cemiplimab)Experimental Treatment4 Interventions

Patients recieve ATRA at a starting dose of 150 mg/m2/day for 3 days orally prior to each cycle of Cemiplimab 350 mg IV q3 weeks for three cycles and then Cemiplimab monotherapy until the progress of disease or unacceptable toxicities develops. Peripheral blood samples will be collected. Patients will undergo physical examination and imaging scans at baseline and then approximately every 6 weeks (2 cycles) for the first year of treatment and every 12 weeks thereafter
