A Randomized, Placebo-Controlled, Double-Blind, Phase II Trial of Nanoparticle Albumin-Bound Paclitaxel (Nab-Paclitaxel, Abraxane®) With or Without Mifepristone for Advanced, Glucocorticoid Receptor-Positive, Triple-Negative Breast Cancer

University of Chicago·interventional·Posted Jun 2, 2016·Updated Jun 10, 2025

In Brief

A Phase 2 clinical trial evaluating Mifepristone, Placebo, and 1 other intervention for Breast Cancer. Active but no longer recruiting, targeting 29 participants across 5 sites.

Detailed Summary

This is a randomized, placebo-controlled, double-blind, phase II trial of nab-paclitaxel with or without mifepristone for advanced, glucocorticoid receptor-positive, triple-negative breast cancer. A total of 64 patients will receive nab-paclitaxel. Patients will be randomly assigned to either receive placebo or to receive mifepristone daily on the day prior to and day of each dose of nab-paclitaxel. Patients will be enrolled over 12 months and followed for 12 months following completion of study. To expand and follow up on the investigators understanding of a potential pharmacokinetic (PK) interaction between nab-paclitaxel and mifepristone, investigators will perform PK studies in the first 20 patients enrolled at pre-specified "PK sites".
