Combination of everolimus with trastuzumab plus paclitaxel as first-line treatment for patients with HER2-positive advanced breast cancer (BOLERO-1): a phase 3, randomised, double-blind, multicentre trial.
Summary
The purpose of this Phase III study was to confirm the value of adding everolimus to weekly paclitaxel and trastuzumab as treatment of HER2-overexpressing metastatic breast cancer.

Eligibility Criteria
Inclusion Criteria
- Adult Women (≥ 18 years old).
- Histologically or cytologically confirmed invasive breast carcinoma with local recurrence or radiological evidence of metastatic disease.
- Must have at least one lesion that can be accurately measured or bone lesions in the absence of measurable disease.
- HER2+ patients by local laboratory testing (IHC 3+ staining or in situ hybridization positive).
- Prior trastuzumab and/or chemotherapy (taxanes included) as neo-adjuvant or adjuvant treatment is allowed but should be discontinued > 12 months prior to randomization.

- Organ functions at time of inclusion.
Exclusion Criteria

- Other anticancer therapy for locally advanced or metastatic breast cancer except for prior hormonal therapy.
- Patients with only non-measurable lesions other than bone metastasis (e.g. pleural effusion, ascites, etc).
- Radiotherapy to ≥ 25% of the bone marrow within 4 weeks prior to randomization
- History of central nervous system metastasis.
- Impairment of gastrointestinal (GI) function or GI disease or active ulceration of the upper gastrointestinal tract.
- Serious peripheral neuropathy.
- Cardiac disease or dysfunction.
- Uncontrolled hypertension.
