Trial Outcomes & Findings for Ixabepilone and Hydroxychloroquine in Treating Patients With Metastatic Breast Cancer (NCT NCT00765765)

NCT ID: NCT00765765

Last Updated: 2023-08-09

Results Overview

Overall Complete Response and Partial Response will be considered tumor response. Ixabepilone as a single agent (40 mg/m2 as an intravenous infusion every 3 weeks) was evaluated in a previous (Phase II) study in women with metastatic breast cancer and that the objective tumor response rate was 11.5%. In another(Phase III) study, Ixabepilone in combination with capecitabine resulted in an objective tumor response rate of 35%, compared to that of capecitabine alone (14%). Therefore, in the Phase II portion of the ixabepilone plus hydroxychloroquine combination treatment study, a tumor response rate of less than 15% will be deemed uninteresting. The target tumor response rate will be 35%. Due to uncertainty about the true response rate of ixabepilone plus hydroxychloroquine combination on this patient poupation, we also will consider a response rate of 30% to be encouraging.
