Eligibility Criteria
Inclusion
- Key inclusion criteria:
- Histologically confirmed adenocarcinoma of the breast.
- MBC (stage IV) at primary diagnosis or at relapse after curative intent therapy.
- Local or central laboratory confirmed HER2/neu overexpressing and/or amplified disease in the invasive component of the primary or metastatic lesion as defined by:
- 3+ over expression by immunohistochemistry (IHC) (\>30% of invasive tumour cells);
- 2+ or 3+ (in 30% or less neoplastic cells) overexpression by IHC analysis AND fluorescence or chromogenic in situ hybridization (FISH/CISH) test demonstrating HER2/neu gene amplification;
- HER2/neu gene amplification by FISH/CISH \[\>6 HER2/neu gene copies per nucleus, or a FISH/CISH ratio (HER2 gene copies to chromosome 17 signals) of \>=2.2\]
- Subjects must have had evidence of metastatic disease, but measurable disease was not mandatory. To be considered evaluable for overall response rate (CR and PR), subjects must have had at least 1 measurable lesion as follows:
- X-ray, physical exam \>=20 mm.
- Conventional computed tomography (CT) scan, magnetic resonance imaging (MRI) \>=20 mm.
- Spiral CT scan \>=10 mm.
- Key exclusion criteria:
- Subjects with a history of other malignancies, except: adequately treated ductal carcinoma in-situ or lobular carcinoma in-situ, adequately treated non-melanoma skin cancer, curatively treated in-situ cancer of the cervix, or other solid tumor (non-breast) curatively treated with no evidence of disease for \>=5 years.
- Subjects who had received prior chemotherapy, immunotherapy, biologic therapy or HER2/neu targeted therapy for recurrent or MBC.
- Subjects receiving ongoing anti-cancer treatment or other investigational anti-cancer agents for breast cancer or subjects who had used an investigational drug within 30 days or 5 half-lives (if known), whichever was longer, preceding the date of randomization.
- Subjects with: CNS metastases (including leptomeningeal involvement), serious cardiac illness, peripheral neuropathy grade 2 or greater, subjects with gastrointestinal tract disease, subjects receiving CYP3A4 inhibitors or inducers, and subjects with history of allergic or hypersensitivity reactions to any study drug or their excipients.
