Experimental: Gemcitabine, Trastuzumab, and Pertuzuma
The regimen will consist of gemcitabine at 1000mg/m^2 IV weekly days 1 + 8 q 3 weeks + trastuzumab every 3 weeks (8 mg/kg loading dose followed by 6 mg/kg every 3 weeks) + pertuzumab every 3 weeks (840 mg as a loading dose followed by 420 mg every 3 weeks), all given intravenously (IV). Trastuzumab may be given IV weekly (4 mg/kg loading dose followed by 2 mg/kg weekly) in lieu of the every 3 week schedule. A loading dose of trastuzumab will not be required for patients who have received it < 6 weeks prior to Cycle 1 Day 1.
- progression free [ Time Frame: 3 months ]Progression-free survival (PFS) is defined from time from treatment assignment to disease progression or death, whichever comes first. The primary endpoint is PFS and secondary endpoint will include the response rate using the RECIST criteria (version 1.1).
- progression-free survival [ Time Frame: 2 years ]Progression-free survival (PFS) is defined from time from treatment assignment to disease progression or death, whichever comes first.
- response [ Time Frame: 2 years ]Response to treatment will be determined using both RECIST and PRC ( PET Response Criteria criteria).
- overall survival [ Time Frame: 2 years ]Progression-free survival and median overall survival will also be estimated by the Kaplan-Meier method.
- safety [ Time Frame: 2 years ]This study will use the NCI Common Toxicity Criteria (CTC) AE version 4.0 for toxicity.
