研究概览
简要总结
The purpose of this study is to determine whether RTA 744 is effective in the treatment of breast cancer that has metastasized to the brain.
详细描述
RTA 744 is a novel, anthracycline that has shown the ability to circumvent ATP-binding cassette transporters (Multidrug Resistance Protein 1, Breast Cancer Resistance Protein, P-glycoprotein) in vitro. This action enables RTA 744 to penetrate across the blood brain barrier. In a Phase I safety study, RTA 744 was shown to be generally well tolerated in patients with recurrent glioblastoma multiforme (GBM). Additionally, anti-tumor activity was observed. Breast cancer is known to be sensitive to anthracycline therapy. Based on the preliminary Phase I clinical results and the sensitivity of breast cancer to anthracycline therapy, this Phase II study will investigate the safety and efficacy of RTA 744 in patients with breast cancer and metastatic disease to the brain which has progressed following whole brain irradiation.
