Study of Durvalumab (MEDI4736) (Anti-PD-L1) and Trametinib (MEKi) in MSS Metastatic Colon Cancer

NCT03428126

Description:

The goal of this clinical research study is to learn if durvalumab and trametinib can help to control microsatellite stable (MSS) colorectal cancer. The safety of these drugs will also be studied. This is an investigational study. Durvalumab is FDA approved and commercially available for the treatment of previously treated advanced bladder cancer. Trametinib is FDA approved in combination with another drug called dabrafenib for the treatment of unresectable or metastatic melanoma with BRAF V600E or BRAF V600K. It is investigational to use durvalumab and trametinib to treat MSS colorectal cancer. Up to 56 participants will be enrolled in this study. All will take part at MD Anderson.

This is an investigational study. Durvalumab is FDA approved and commercially available for the treatment of previously treated advanced bladder cancer.

Detailed Description

      Study Drug Administration:

      Each cycle is 28 days.

      Participant will take trametinib tablets by mouth every day with at least 8 ounces of water.
      Each dose should be taken at about the same time each day, 1 hour before or 2 hours after a
      meal. Participant should not crush, cut, or chew the tablets. If participant misses a dose of
      trametinib, participant may take the tablets as soon as participant remembers but only if
      participant's next scheduled dose is at least 12 hours later. If participant's next scheduled
      dose is less than 12 hours, participant should wait and take participant's next dose as
      scheduled.

      Participant will take trametinib alone for the first 7 days of the study and then participant
      will begin receiving it in combination with durvalumab.

      Every 4 weeks, participant will receive durvalumab by vein over about 60 minutes.

      Length of Treatment:

      Participant will be able to receive the study drugs for as long as the doctor thinks it is in
      participant's best interest. Participant no longer will take the study drugs if intolerable
      side effects occur or if the study doctor decides that the drugs are no longer working.

      It is expected that participation in this study may last about 12 months.

      Participation in this study will be over after follow-up.

      Study Visits:

      On Day 1 of Weeks 0, 2, 4, 6, 12, and then every 4 weeks after that (Weeks 16, 20, 24, and so
      on):

        -  Participant will have a physical exam.

        -  Blood (about 6 tablespoons) will be drawn for routine tests, immune system testing, and
           biomarker testing.

        -  If participant had a biopsy at screening, participant will have another biopsy during
           Week 4 to check the status of the disease and for biomarker testing. Depending on when
           participant joins the study, this biopsy may be optional.

      On Day 1 of Week 8:

        -  Participant will have a physical exam.

        -  Blood (about 6 tablespoons) will be drawn for routine tests, immune system testing, and
           biomarker testing.

        -  Participant will have a CT scan.

      On Day 1 of Week 16 and then every 8 weeks after that (Weeks 24, 32, 40, and so on),
      participant will have a CT scan.

      End-of-Treatment:

      About 28 days after participant's last dose of study drugs, participant will have a physical
      exam.

      Follow-Up:

      After participant's end-of-treatment visit, participant will be called by the study staff
      every 3 months for up to 18 months to ask how participant is doing. Each call should last
      about 5-10 minutes.

             (>10 mg daily prednisone equivalents) or other immunosuppressive medications within 14
             days of study drug administration. Inhaled or topical steroids and adrenal replacement
             doses > 10 mg daily prednisone equivalents are permitted in the absence of active
             autoimmune disease.

             arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions
             associated with diarrhea, or psychiatric illness/social situations that would limit
             compliance with study requirements, substantially increase risk of incurring AEs or
             compromise the ability of the patient to give written informed consent.
