SARC018-SPORE01 April 23, 2021 SARC018: A Study of Mocetinostat and Gemcitabine in Patients With Metastatic Leiomyosarcoma TYPE OF SARCOMA: Metastatic LeiomyosarcomaDRUG: Mocetinostat & Gemcitabine ACCRUAL STATUS: Completed OVERALL STUDY PRINCIPAL INVESTIGATORS:Shreyas Patel, MDCo-Principal InvestigatorMD Anderson Cancer CenterEdwin Choy, MD, PhDCo-Principal InvestigatorMGH, Dana Farber/Harvard Cancer CenterDivision of Hematology Oncology CLINICALTRIALS.GOV IDENTIFIER: NCT02303262 FOR STUDY DETAILS AND ELIGIBILITY CRITERIA: CLINICALTRIALS.GOV IMPACT STATEMENT:Based on laboratory evidence that HDAC inhibition can help overcome chemoresistance, enhance chemotherapy induced cytotoxicity and decrease tumor cell proliferation, this clinical trial was designed as part of the SARC SPORE project 2. Mocetinostat was given along with Gemcitabine in patients with metastatic LMS who had documented progression after prior exposure to Gemcitabine. We showed feasibility, proof of principle activity, and safety for this combination. However, the trial was terminated after completion of the first stage due to limited response rate observed at interim analysis.
