Trial of Selumetinib and Bromodomain Inhibitor With Durvalumab for Sarcomas

Launched by UNIVERSITY OF ALABAMA AT BIRMINGHAM · Feb 14, 2022

ClinConnect Summary

This clinical trial is investigating a new treatment approach for certain types of sarcomas, specifically focusing on a combination of three drugs: selumetinib, a bromodomain inhibitor (BI), and durvalumab. This study aims to find out how effective these drugs are for patients whose sarcomas have not responded to standard treatments. The trial will take place in several locations and is divided into two parts. The first part will include patients with various types of soft tissue or bone sarcomas, while the second part will specifically focus on patients with a rare type of sarcoma called malignant peripheral nerve sheath tumor (MPNST) that is associated with a condition known as neurofibromatosis type 1 (NF1).

To be eligible for the trial, participants must be at least 18 years old, weigh more than 30 kg, and have sarcomas that have not responded to previous therapies. Patients should have a life expectancy of at least 12 weeks and must have measurable disease to participate. Participants will need to have recovered from any recent cancer treatments before joining the study. While the trial is not yet recruiting, those who qualify may have the opportunity to receive new treatment options. It’s important for potential participants to discuss with their healthcare team whether this trial might be a good fit for them.
