A Global, Multicenter, Three Arms, Open-label Randomized Study to Evaluate the Efficacy and Safety of Nanosomal Docetaxel Lipid Suspension Compared to Taxotere® (Docetaxel Injection Concentrate) in Triple-negative Breast Cancer Patients With Locally Advanced or Metastatic Breast Cancer After Failure to Prior Chemotherapy
The Nanosomal Docetaxel Lipid Suspension (NDLS) consists of uniformly sized micro particles of docetaxel suspended in a lipid based formulation. The advantage of such a Lipid Based formulation of Docetaxel is an improvement of the safety profile by eliminating excipients, polysorbate 80 and ethanol which are present in conventional Docetaxel formulations (Taxotere®). This randomized, open-label study is designed to assess the efficacy and safety of Nanosomal Docetaxel Lipid Suspension at the dose of 75 mg/m2 and at the dose of 100 mg/m2 compared to Taxotere® at the dose of 100 mg/m2 in triple-negative breast cancer patients with Locally Advanced or Metastatic Breast Cancer. Patients will continue the treatment in the absence of disease progression and unacceptable toxicity. Disease status and tumor response will be assessed using Response Evaluation Criteria in Solid Tumors (RECIST 1.1) guidelines. 657 patients (219 patients per arm) will be randomized in the study. The trial will be conducted as per the ICH GCP Guidelines E6 (R1), Schedule Y (Amended Version 2013), Declaration of Helsinki (Fortaleza, Brazil, October 2013), ICMR Guidelines for Biomedical Research on Human subjects and in accordance with other applicable guidelines.

⁃ Patients with life expectancy of at least 6 months.
⁃ Serum pregnancy test at screening and urine pregnancy test on Day 1 (before randomization) must be negative.
⁃ Sexually active women, unless surgically sterile or postmenopausal for at least 12 consecutive months, must use an effective method of avoiding pregnancy (including oral, transdermal, or implanted contraceptives \[any hormonal method in conjunction with a secondary method\], intrauterine device, female condom with spermicide, diaphragm with spermicide, absolute sexual abstinence, use of condom with spermicide by sexual partner or sterile \[at least 6 months prior to Study drug administration\] sexual partner) for at least four weeks prior to study drug administration, during study and up to 30 days after the last dose of study drug.
