Summary

This trial is comparing the effectiveness of a combination treatment using olaparib and temozolomide to the common chemotherapy drugs trabectedin or pazopanib. The trial is for patients

Who is the study for?

This trial is for adults with advanced uterine leiomyosarcoma that has worsened after at least two prior treatments, including an anthracycline. Participants must have measurable disease, be in relatively good health (ECOG <=2), and women must test negative for pregnancy. Those with significant treatment-related side effects or who haven't recovered from previous therapies are excluded.

What is being tested?

The study compares a new combination of drugs (Olaparib and Temozolomide) against standard chemotherapy options (Trabectedin or Pazopanib) for advanced uterine leiomyosarcoma post-initial chemo failure. Olaparib may prevent tumor DNA repair, while Temozolomide aims to slow tumor growth.

What are the potential side effects?

Possible side effects include nausea, fatigue, blood cell count changes leading to increased infection risk or bleeding problems, hair loss which is usually temporary, digestive issues like constipation or diarrhea, and potential allergic reactions.

Trial Design

2Treatment groups

Experimental Treatment

Active Control

Group I: Arm 1 (olaparib, temozolomide)Experimental Treatment8 Interventions

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.

Group II: Arm 2 (trabectedin, pazopanib)Active Control8 Interventions

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.
