Gemcitabine, Trastuzumab, and Pertuzumab in the Treatment of Metastatic HER2-Positive Breast Cancer After Prior Trastuzumab/Pertuzumab, or Pertuzumab Based Therapy

NCT02252887

Description:

The purpose of this study is to see if a combination of drugs can help to treat breast cancer. This is a Phase II study which will test whether this combination of drugs is effective and will provide further information on side effects and safety. A standard chemotherapy, gemcitabine, will be combined with 2 other drugs that target the HER2 receptor. The HER2 receptor is a growth protein on the surface of some breast cancer cells that provides messages telling the breast cancer cell to grow. The standard chemotherapy will be gemcitabine.. The other two drugs work against HER2. One is called trastuzumab (Herceptin) and it is commonly given to women with advanced and early HER2 positive breast cancer. The other drug, pertuzumab (Perjeta), is also given to women with advanced HER2 positive breast cancer. The drugs in this study are each individually approved for the treatment of metastatic breast cancer. However, this study is looking at the effectiveness of gemcitabine with trastuzumab and pertuzumab when given to women who have advanced HER2 positive breast cancer who have had prior trastuzumab + pertuzumab or pertuzumab-based therapy.

NameTypeDescriptionInterventions
Gemcitabine, Trastuzumab, and PertuzumaExperimentalThe 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.

Eligibility Criteria

        Inclusion Criteria:

          -  Age ≥ to 18

          -  Stage IV HER2 (+) breast cancer

          -  Histologically documented HER2 (+) breast cancer as defined as IHC 3+ or FISH
             amplification of ≥ 2.0 of primary or metastatic site; results from the local lab are
             acceptable.

          -  lECOG performance status 0 -1

          -  Prior treatment with trastuzumab + pertuzumab (HP)-based therapy or pertuzumab-based
             in the neoadjuvantadjuvant, unresectable, locally advanced, or metastatic setting.

          -  ≤ 3 prior chemotherapies in the metastatic setting. Prior anthracycline, taxane,
             gemcitabine, and anti-HER2 agents (i.e. trastuzumab, pertuzumab, lapatinib, neratinib,
             TDM-1, etc.) are allowed. If patients received prior gemcitabine, it could not have
             been combined with pertuzumab. Patients should have progression of disease on current
             therapy.
