Trial Description

Summary

This randomized phase II trial studies how well fludarabine and rituximab with or without lenalidomide or cyclophosphamide works in treating patients with symptomatic chronic lymphocytic leukemia. Drugs used in chemotherapy, such as fludarabine and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Lenalidomide may stimulate the immune system in different ways and stop cancer cells from growing. Giving fludarabine and rituximab together with lenalidomide or cyclophosphamide may kill more cancer cells.

Further Study Information

PRIMARY OBJECTIVES:

I. To determine the two-year progression-free survival (PFS) after remission induction with four different chemo-immunotherapy combinations for patients with untreated, symptomatic, lower-risk and high-risk chronic lymphocytic leukemia (CLL) to decide which of the four arms, if any, to take forward into a randomized phase III trial.

II. To determine the induction response to fludarabine phosphate and rituximab (FR) and fludarabine phosphate, cyclophosphamide, and rituximab (FCR) in each of these arms, along with the consolidation response to lenalidomide in patients with CLL.

III. To determine the toxicity from these four chemoimmunotherapy combinations and that of consolidation therapy with lenalidomide.

IV. To determine the induction response and toxicity of FCR in patients with deletion (del) (11q22.3) along with consolidation response, 2-year PFS and toxicity of lenalidomide in this specific genetic group.

V. To determine the effect of pretreatment biologic characteristics on clinical outcomes, such as attaining a complete response to induction therapy and progression-free survival.

VI. To collect relapse samples to determine the frequency of clonal evolution among patients with immunoglobulin heavy chain variable region (IgVH) mutated and unmutated disease and to study mechanisms of resistance to chemoimmunotherapy.

VII. To determine if flow cytometry-negative status immediately post-therapy and at 24 months after study entry is an effective surrogate marker for prolonged progression-free survival and overall survival.

OUTLINE: Patients are randomized to 1 of 3 treatment arms (Arms A, B, or C). Patients on Arm A or B who are found to be del (11q22.3) positive are assigned to Arm D beginning with course 2 of induction therapy.

ARM A (remission-induction [RI] therapy with fludarabine phosphate and rituximab): Patients receive rituximab intravenously (IV) over 1-4 hours on days 1, 3, and 5 of course 1 and on day 1 of all subsequent courses. Patients also receive fludarabine phosphate IV over 30 minutes or orally (PO) on days 1-5. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression.

ARM B (RI therapy with fludarabine phosphate and rituximab followed by remission-consolidation [RC] therapy with lenalidomide): Patients undergo RI therapy as in Arm I. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression. Patients with a complete or partial response or stable disease proceed to RC therapy beginning approximately 4 months after completing the last dose of fludarabine phosphate in course 6, comprising lenalidomide PO once daily (QD) on days 1-21. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

ARM C (RI therapy with fludarabine phosphate, rituximab, and cyclophosphamide): Patients receive rituximab IV over 4 hours on days 1 and 3 of course 1 and on day 1 of all subsequent courses. Patients then receive fludarabine phosphate IV piggyback over 30 minutes or PO followed by cyclophosphamide IV piggyback over 30 minutes on days 1-3. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression.

ARM D (RI therapy with fludarabine phosphate, rituximab, and cyclophosphamide followed by RC therapy with lenalidomide): Patients receive the first course of RI therapy as in Arm A or B before being re-assigned to Arm D. Beginning in course 2, patients receive rituximab IV on day 1 and fludarabine phosphate IV piggyback over 30 minutes or PO and cyclophosphamide IV piggyback over 30 minutes on days 1-3. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression. Patients with a complete or partial response or stable disease proceed to RC therapy beginning approximately 4 months after completing the last dose of fludarabine phosphate in course 6, comprising lenalidomide PO QD on days 1-21. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed up every 3 months for 1 year and then every 6 months for up to 15 years.
