Durvalumab and Tremelimumab Before Surgery in Treating Patients With Hormone Receptor Positive, HER2 Negative Stage II-III Breast Cancer



This early phase I trial studies the side effects of durvalumab and tremelimumab before surgery in treating patients with hormone receptor positive, HER2 negative stage II-III breast cancer. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

The goal of this clinical research study is to find the highest dose combination of tremelimumab and durvalumab [also called MEDI4736]) that can be given before standard of care pre-surgery chemotherapy to patients with HR+, HER2- breast cancer. Researchers also want to learn more about how certain immune cells may change in the body when they are given the drug combination. Researchers also want to find out how patients with HR+, HER2- breast cancer respond to the study drugs before they receive standard chemotherapy treatment.

Detailed Description

      Study Drug Administration:

      If you are found to be eligible to take part in this study, you will receive both study
      drugs in 2 study cycles that are each 4 weeks long. On Day 1 of each cycle, you will first
      receive tremelimumab by vein over about 1 hour. You will then be monitored for side effects
      for about 1 hour. You will then receive durvalumab by vein over about 1 hour, followed by
      another hour of monitoring for side effects.

      Length of Study:

      You will receive up to 2 cycles of the study drugs. You will no longer be able to take the
      study drug if the disease gets worse, if intolerable side effects occur, or if you are
      unable to follow study directions.

      Your participation on the study will be over after the follow-up visits.

      Study Procedures:

      Before you receive the study drugs for the first time:

        -  You will have a core breast tumor biopsy before you begin treatment to collect tissue
           to test for immune cells and other biomarkers. Biomarkers are found in the blood/tissue
           and may be related to your reaction to the study drug. To perform a core biopsy, the
           area is numbed and a sample of tissue is removed using a hollow core needle that has a
           cutting edge.

        -  If your screening blood test was performed more than 3 days before you begin receiving
           the study drugs, blood (about 14 teaspoons) will be drawn for the same testing
           performed during the screening.

      On Day 1 of Cycles 1 and 2:

        -  You will have a physical exam.

        -  Blood (about 5 tablespoons) and urine will be collected for routine tests.

        -  You will have an EKG to check your heart function (Cycle 1 only).

      At the end of Cycle 2:

        -  You will have a physical exam.

        -  Blood (about 3 tablespoons) will be drawn for routine tests and to check for immune
           cells and other biomarkers.

        -  You will have a second ultrasound of your breast.

        -  You will have a second core breast tumor biopsy to compare to the tissue taken before
           you started treatment.

      After this visit, you will then begin receiving the standard of care treatment for the
      disease (pre-surgery chemotherapy followed by surgery). During your surgery, blood and tumor
      samples will be collected to compare to the samples taken during the study. However, no
      additional tissue or blood will be collected beyond what is already collected for the
      standard purposes of the surgery.

      This is an investigational study. Tremelimumab is FDA approved to treat mesothelioma.
      Durvalumab is FDA approved to treat a certain type of bladder cancer. It is investigational
      to give these 2 drugs in combination to patients with HR+, HER2- breast cancer. The study
      doctor can describe how the study drugs are designed to work.

      Up to 15 participants will be enrolled in this study. All will take part at MD Anderson.
