Breast Cancer
Conditions
Brief summary
This single-arm study assessed the efficacy and safety of first-line treatment with Avastin (bevacizumab) in combination with taxane-based chemotherapy (paclitaxel and gemcitabine) in patients with HER-2 negative breast cancer. Patients received Avastin 10 mg/kg iv, paclitaxel 150 mg/m\^2 iv, and gemcitabine 200 mg/m\^2 iv on Day 1 and Day 15 of each 4-week treatment cycle until disease progression, death, or withdrawal of consent.
Interventions
Bevacizumab was supplied as a sterile liquid in glass vials.
Paclitaxel was supplied as a sterile liquid in glass vials.
Gemcitabine was supplied as a sterile liquid in glass vials.

Eligibility
Inclusion criteria
* Female patients, ≥ 18 years of age. * Breast cancer, with measurable, locally recurrent or metastatic lesions, or patients with bone metastasis only. * HER-2 negative disease. * Candidates for chemotherapy. * Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.
Exclusion criteria
* Previous chemotherapy for metastatic or locally advanced breast cancer. * Previous radiotherapy for treatment of metastatic breast cancer. * Any prior adjuvant treatment with anthracyclines completed \< 6 months prior to enrollment. * Chronic daily treatment with corticosteroids (≥ 10 mg/day), aspirin (\> 325 mg/day) or clopidogrel (\> 75mg/day).
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free Survival | Baseline to the end of the study (up to 2 years 10 months) | Progression-free survival was defined as the time from enrollment in the study to the first documented disease progression using Response Evaluation Criteria In Solid Tumors (RECIST) or death from any cause, whichever occurred first. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With an Objective Response | Baseline to the end of the study (up to 2 years 10 months) | An objective response was defined as a complete or partial response determined on 2 consecutive occasions ≥ 4 weeks apart using Response Evaluation Criteria in Solid Tumors (RECIST). Complete response was defined as the disappearance of all target and non-target lesions. Any pathological lymph nodes (whether target or non-target) must be \< 10 mm on the short axis. Partial response was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum. |
| Duration of the Objective Response | Baseline to the end of the study (up to 2 years 10 months) | Duration of the objective response is defined as the time from a complete or partial response to disease progression or death due to disease. |
| Overall Survival | Baseline to the end of the study (up to 2 years 10 months) | Overall survival is defined as the time from the first dose of study medication until death. |

Outcome results
Progression-free Survival
Progression-free survival was defined as the time from enrollment in the study to the first documented disease progression using Response Evaluation Criteria In Solid Tumors (RECIST) or death from any cause, whichever occurred first.
Time frame: Baseline to the end of the study (up to 2 years 10 months)
Population: Intent-to-treat population: All participants who were enrolled in the study.
| Arm | Measure | Value (MEDIAN) |
|---|---|---|
| Bevacizumab + Paclitaxel + Gemcitabine | Progression-free Survival | 11.51 Months |
Duration of the Objective Response
Duration of the objective response is defined as the time from a complete or partial response to disease progression or death due to disease.
Time frame: Baseline to the end of the study (up to 2 years 10 months)

Percentage of Participants With an Objective Response
An objective response was defined as a complete or partial response determined on 2 consecutive occasions ≥ 4 weeks apart using Response Evaluation Criteria in Solid Tumors (RECIST). Complete response was defined as the disappearance of all target and non-target lesions. Any pathological lymph nodes (whether target or non-target) must be \< 10 mm on the short axis. Partial response was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum.
Time frame: Baseline to the end of the study (up to 2 years 10 months)
Population: Intent-to-treat population: All participants who were enrolled in the study. Only participants who had a response evaluation were included in the analysis.
