phase iii study of docetaxel + ramucirumab or placebo in breast cancer

Conditions: Breast Cancer

Summary: the objective of this study is to compare the progression-free survival (pfs) of the drug combination ramucirumab plus docetaxel to placebo plus docetaxel in previously untreated participants with human epidermal growth factor receptor 2 (her2)-negative, unresectable, locally-recurrent or metastatic 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.

if urine protein ≥ 2+, a 24-hour urine collection must demonstrate \< 1000 milligrams (mg) of protein in 24 hours to allow participation in the study * participant must have adequate coagulation function as defined by international normalized ratio (inr) ≤ 1.5 and a partial thromboplastin time (ptt) ≤ 1.5 x uln if not receiving anticoagulation therapy. participants on full-dose anticoagulation must be on a stable dose of oral anticoagulant or low molecular weight heparin and if on warfarin must have a inr between 2 and 3 and have no active bleeding (defined as within 14 days of randomization) or pathological condition that carries a high risk of bleeding (such as, tumor involving major vessels or known varices) * women of childbearing potential must implement adequate contraception in the opinion of the investigator * participant has not received prior biologic therapy for metastatic or locally recurrent and inoperable breast cancer exclusion criteria: * participant has a concurrent active malignancy other than breast adenocarcinoma, adequately treated non melanomatous skin cancer, or other non-invasive carcinoma or in situ neoplasm. a participant with previous history of malignancy is eligible, provided that she has been disease free for \> 3 years * participant has a known sensitivity to docetaxel or other drugs formulated with polysorbate 80 * participant has a known sensitivity to agents of similar biologic composition as ramucirumab or other agents that specifically target vascular endothelial growth factor (vegf) * participant has a history of chronic diarrheal disease within 6 months prior to randomization * participant has received irradiation to a major bone marrow area as defined as \> 25% of bone marrow (such as, pelvic or abdominal radiation) within 30 days prior to randomization * participant has participated in clinical trials of experimental agents within 4 weeks prior to randomization * participant has a history of uncontrolled hereditary or acquired bleeding or thrombotic disorders * participant has active, high risk bleeding (such as, via gastric ulcers or gastric varices) within 14 days prior to randomization * participant has an ongoing or active infection requiring parenteral antibiotic, antifungal, or antiviral therapy * participant has uncontrolled hypertension, symptomatic congestive heart failure, unstable angina pectoris, symptomatic or poorly controlled cardiac arrhythmia, psychiatric illness/social situations, or any other serious uncontrolled medical disorders in the opinion of the investigator * participant has brain metastases, uncontrolled spinal cord compression, or carcinomatous meningitis, or new evidence of brain or leptomeningeal disease * participant has known human immunodeficiency virus infection or acquired immunodeficiency syndrome-related illness * participant has pulmonary lymphangitic involvement that results in pulmonary dysfunction requiring active treatment, including the use of oxygen. * participant is pregnant or lactating
