Phase III Study of Docetaxel + Ramucirumab or Placebo in Breast Cancer

Female participants at least 18 years of age with histologically or cytologically confirmed, human epidermal growth factor receptor 2 (HER2) negative breast adenocarcinoma that is metastatic or locally-recurrent and inoperable with curative intent will be randomized. Participants may not have received chemotherapy for metastatic or locally-recurrent, inoperable breast cancer. It is anticipated that 1113 participants will be randomized with 371 participants in the docetaxel plus placebo arm and 742 participants in the docetaxel plus ramucirumab (IMC-1121B) arm. There will be approximately 250 centers in North and South America, Europe, Asia, Middle East, Africa, Australia, and New Zealand. On Day 1 of each 21-day cycle, participants will receive docetaxel 75 mg/m² as a one-hour I.V. infusion followed by either ramucirumab (IMC-1121B) 10 mg/kg or placebo 10 mg/kg as a one-hour I.V. infusion. Each cycle is repeated every 21 days. Treatment will continue until there is evidence of progressive disease, unacceptable toxicity, or other withdrawal criteria are met. Participants who discontinue study treatment with either ramucirumab (IMC-1121B) or placebo may continue to receive docetaxel.
