A Randomized Phase 2/3 Study of Olaparib Plus Temozolomide Versus Investigator's Choice for the Treatment of Patients With Advanced Uterine Leiomyosarcoma After Progression on Prior Chemotherapy

National Cancer Institute (NCI)·interventional·Posted Jun 27, 2022·Updated Jun 1, 2026

In Brief

A Phase 2 clinical trial evaluating Biospecimen Collection, Bone Scan, and 8 other interventions for Locally Advanced Uterine Corpus Leiomyosarcoma and 4 related conditions. Active but no longer recruiting, targeting 74 participants across 145 sites in 2 countries.

Detailed Summary

This phase II/III trial compares the effect of the combination treatment with olaparib and temozolomide to trabectedin or pazopanib (two of the most common chemotherapy drugs used as usual approach) in patients with uterine leiomyosarcoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) after initial chemotherapy has stopped working. The usual approach is defined as care most people get for advanced uterine leiomyosarcoma. Olaparib is a PARP inhibitor. PARP is a protein that helps repair damaged deoxyribonucleic acid (DNA). Blocking PARP may prevent tumor cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Temozolomide is in a class of medications called alkylating agents. It works by slowing or stopping the growth of tumor cells in the body. The combination of olaparib and temozolomide may work better than the usual treatment in shrinking or stabilizing advanced uterine leiomyosarcoma after initial chemotherapy has stopped working.

Arms & Interventions

Arm 1 (olaparib, temozolomide)experimental

Patients receive temozolomide PO QD on days 1-7 of each cycle and olaparib PO BID on days 1-7 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan or MRI and/or bone scans throughout the trial. Patients also undergo collection of blood samples throughout the trial.

Arm 2 (trabectedin, pazopanib)active_comparator

Patients receive trabectedin IV continuously over 24 hours on day 1 of each cycle or pazopanib PO QD on days 1-21 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan or MRI and/or bone scans throughout the trial. Patients also undergo TTE or MUGA on study and as clinically indicated, as well as collection of blood samples throughout the trial.
