Ibrutinib and Rituximab Compared With Fludarabine Phosphate, Cyclophosphamide, and Rituximab in Treating Patients With Untreated Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma

This randomized phase III trial studies ibrutinib and rituximab to see how well they work compared to fludarabine phosphate, cyclophosphamide, and rituximab in treating patients with untreated chronic lymphocytic leukemia or small lymphocytic lymphoma. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as rituximab, interfere with the ability of cancer cells to grow and spread. It is not yet known whether fludarabine phosphate, cyclophosphamide, and rituximab may work better than ibrutinib and rituximab in treating patients with untreated chronic lymphocytic leukemia or small lymphocytic lymphoma.

Stanford is currently not accepting patients for this trial.

Eligibility

            - The predominant population of lymphocytes share both B-cell antigens
            (cluster of differentiation [CD]19, CD20 [typically dim expression], or
            CD23) as well as CD5 in the absence of other pan-T-cell markers (CD3,
            CD2, etc)

            - Clonality as evidenced by kappa or lambda light chain restriction
            (typically dim immunoglobulin expression)

      - Negative FISH analysis for t(11;14)(immunoglobulin heavy locus [IgH]/cyclin D1
      [CCND1]) on peripheral blood or tissue biopsy (e.g. marrow aspirate) or negative
      immunohistochemical stains for cyclin D1 staining on involved tissue biopsy (e.g.
      marrow aspirate or lymph node biopsy)

   - No prior chemotherapy, Bruton's tyrosine kinase (BTK) inhibitor therapy, or monoclonal
   anti-body therapy for treatment of CLL or SLL

   - Has met at least one of the following indications for treatment:

   for those with a total bilirubin > 2.5 x ULN, a direct bilirubin should be performed
   and must be < 1.5 mg/dL for Gilbert's to be diagnosed; if value is higher due to
   hepatic involvement by CLL, patient is eligible

   eligible

   thromboplastin time (PTT) activated partial thromboplastin time (aPTT) < 1.5 X ULN; if
   value is higher due to hepatic involvement by CLL, patient is eligible

   treatment; patients who have a positive Coombs test but no evidence of hemolysis are
   NOT excluded from participation
