A Study of ACP-196 Versus Ibrutinib in Previously Treated Subjects with High Risk Chronic Lymphocytic Leukemia

Study Summary

  • Study patients will be randomized (like the flip of a coin) into one of two groups
      • Arm A: You will take ACP-196 two times a day. The treatment is a 100 mg capsule that you will take orally.
      • Arm B: You will take Ibrutinib once a day. The treatment is to take 3 capsules of Ibrutinib 420 mg orally.
  • For either treatment arm, you will continue the treatment as long as possible. You will only stop taking your treatment if your disease progresses, you become sick from the treatment or you or your physician feel that is it in your best interest to stop the study
