E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Advanced or metastatic breast cancer with ErbB2 FISH postive tumours |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the rate of disease progression at 12 weeks between pazopanib in combination with lapatinib versus lapatinib alone in subjects with locally advanced or metastatic breast cancer whose tumors are ErbB2 FISH+. |
|
E.2.2 | Secondary objectives of the trial |
Compare Week 12 response rate between subjects treated with pazopanib in combination with lapatinib versus subjects treated with lapatinib alone. Compare overall survival (OS), time to response and duration of response between subjects treated with pazopanib in combination with lapatinib versus subjects treated with lapatinib alone. Evaluate the safety and tolerability of the combination of pazopanib and lapatinib compared to lapatinib alone in this subject population.

E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
E.3 | Principal inclusion criteria |
1. Women >21 years of age with a life expectancy of >12 weeks. 2. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1. 3. Histologically confirmed invasive breast cancer with incurable stage IIIb, stage IIIc with T4 lesion, or stage IV disease at primary diagnosis or at relapse after curative-intent surgery. 4. Documented amplification of ErbB2 by FISH in either the primary or metastatic tumor tissue. Archived tumor tissue must be provided for ErbB2 FISH testing by the central laboratory, which will be used to determine eligibility. Note: Subjects that have documented ErbB2 amplification based on prior FISH testing are eligible, however, archived tumor tissue must be provided for re-confirmation by the central laboratory. If the results from the central laboratory are unconfirmed, then the subject can continue to receive study drug(s) at the discretion of the investigator, but will be excluded from the statistical analysis and replaced. 5. Disease must be measurable according to Response Evaluation Criteria in Solid Tumors (RECIST). 6. No prior chemotherapy, immunotherapy, biologic therapy or anti-ErbB1/ErbB2 therapy for metastatic or recurrent disease (other than neoadjuvant or adjuvant therapy). Prior hormonal therapy (e.g., tamoxifen, raloxifen or an aromatase inhibitor) for advanced or metastatic disease is permitted provided at least 2 weeks have elapsed between the completion of the prior therapy and start of study drugs. 7. Cardiac ejection fraction within the institutional range of normal as measured by echocardiogram. MUGA scans will be accepted in cases where an echocardiogram cannot be performed or is inconclusive or where MUGA scans are the accepted standard. Subjects with known history of uncontrolled or symptomatic angina, arrhythmias, or congestive heart failure are not eligible.

E.4 | Principal exclusion criteria |
1. History or clinical evidence of central nervous system (CNS) metastases or leptomeningeal carcinomatosis, except for individuals who have previously treated CNS metastases, are asymptomatic, and have had no requirement for steroids or antiseizure medication for >2 months prior to study enrollment. Routine screening with CNS imaging studies (computed tomography [CT] or magnetic resonance imaging [MRI]) is required only if clinically indicated or if the subject has a history of CNS metastases. 2. Sarcoma histology 3. Concurrent cancer therapy (chemotherapy, radiation therapy, surgery, immunotherapy, biologic therapy, hormonal therapy, and tumor embolization). 4. Concurrent treatment with an investigational agent or participation in another clinical trial. 5. Use of an investigational anti-cancer drug within 30 days or 5 half-lives, whichever is longer, preceding the first dose of pazopanib and/or lapatinib. 6. Prior use of an investigational or licensed drug that targets either VEGF or VEGF receptors, or ErbB2 (except for trastuzumab when used in the neo-adjuvant/adjuvant setting). |
