Chloroquine With Taxane Chemotherapy for Advanced or Metastatic Breast Cancer After Anthracycline Failure (CAT) — CAT  

Breast Cancer Clinical Trial

Official title: Phase II Study of The Efficacy And Safety of Chloroquine (C) in CombinAtion With Taxane or Taxane-like (T) Chemo Agents in The Treatment of Patients With Advanced or Metastatic Breast Cancer Who Have Failed Anthracycline Chemo Base Therapy

Status Completed

Clinical Trial Summary

The major purpose of this research study is to better understand how therapy works on different patients. This study is being offered to patients with a diagnosis of advanced or metastatic breast cancer who have failed anthracycline based therapy.

The investigators want to see the response of breast cancer cell when treated with Chloroquine used in combination with chemotherapy. Chemotherapy is an anti-cancer drug that is given through your vein. The chemotherapy used in this study is either Taxane (Paclitaxel) or Taxane-like drugs (Abraxane, Ixabepilone or Docetaxel).

Clinical Trial Description

The purpose of this study is to determine the anti-tumor activity of the combination of Chloroquine combined with a Taxane or Taxane-like chemo agents(Paclitaxel, Docetaxel, Abraxane, Ixabepilone).

The laboratories have developed robust preclinical models utilizing both in vitro systems such as the mammosphere (MS) culture and in vivo systems such as human breast cancer xenografts allowing the investigators to identify agents which selectively target TICs, as single agents or in combination. These models are critical since tumor initiating cells (TICs) comprise only a small percentage of the tumor bulk, so that clinical tumor regression may not be observed with inhibitors that selectively target TIC self-renewal alone. Nonetheless, these agents in combination with conventional therapy may effectively kill both actively cycling or fully differentiated cells and the TIC subpopulation, leading to long term remission and eradication of cancer cells. ;
