A Study of Bevacizumab (Avastin) in Women With HER2 Negative Metastatic Breast Cancer

Phase 3
Completed
Conditions
Breast Cancer
Interventions
Drug: Placebo to bevacizumab
Registration Number
NCT00333775
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This study will evaluate the efficacy and safety of 2 doses of Avastin in combination with docetaxel, versus docetaxel plus placebo, in patients with metastatic HER2 negative breast cancer who are candidates for taxane-based chemotherapy but who have not received prior chemotherapy for metastatic disease. The anticipated time on treatment is 1-2 years and the target sample size is 500+ individuals.

Detailed Description

Five participants randomized to the docetaxel 100 mg/m\^2 plus placebo group actually received docetaxel 100 mg/m\^2 plus bevacizumab 7.5 mg/kg and are included in the docetaxel 100 mg/m\^2 plus bevacizumab 7.5 mg/kg group for the adverse event results. Sixteen participants randomized to the docetaxel 100 mg/m\^2 plus placebo group actually received docetaxel 100 mg/m\^2 plus bevacizumab 15.0 mg/kg and are included in the docetaxel 100 mg/m\^2 plus bevacizumab 15.0 mg/kg group for the adverse event results.

Docetaxel 100 mg/m^2 plus placeboPlacebo to bevacizumabParticipants received docetaxel 100 mg/m\^2 intravenously on Day 1 of each 3 week cycle for a maximum of 27 weeks (9 cycles). In addition, participants received placebo to bevacizumab intravenously on Day 1 of each 3 week cycle until disease progression, unacceptable toxicity, or participant withdrawal.

Primary Outcome Measures
NameTimeMethod
Progression-free SurvivalBaseline to the 15 Sep 2008 cut-off date (up to 2 years, 6 months)

Progression-free survival was evaluated using Response Evaluation Criteria In Solid Tumors (RECIST 1.0). Progression-free survival was defined as the time from randomization to the time of the first documented disease progression or death, whichever occurred first. Disease progression was defined as ≥ 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since treatment started or the unequivocal progression of existing non-target lesions, or appearance of new lesion(s).

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With a Complete Response or a Partial ResponseBaseline to the 15 Sep 2008 cut-off date (up to 2 years, 6 months)

Responses were evaluated using the Response Evaluation Criteria in Solid Tumors. A complete response was defined as the disappearance of all target lesions or the disappearance of all non-target lesions and normalization of tumor marker level. A partial response was defined as at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter.

Duration of ResponseBaseline to the 15 September 2008 cut-off date (up to 2 years, 6 months)

Duration of response was defined as the time from the first documented complete response or partial response to disease progression or death. A complete response was defined as the disappearance of all target lesions or the disappearance of all non-target lesions and normalization of tumor marker level. A partial response was defined as at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter. Responses were evaluated using the Response Evaluation Criteria in Solid Tumors.

Time to Treatment FailureBaseline to the 15 September 2008 cut-off date (up to 2 years, 6 months)

Time to treatment failure was defined as time from randomization to the date of disease progression, death, or withdrawal of treatment due to an adverse event, withdrawal of informed consent, insufficient therapeutic response, refusal of treatment/failure to co-operate, or failure to return, whichever occurred first.

Overall SurvivalBaseline to the 15 Sep 2008 cut-off date (up to 2 years, 6 months)

Overall survival was defined as the time from randomization to death from any cause.
