  Purpose

This is a multi-center, Phase II, open label trial evaluating the efficacy and safety of alemtuzumab and fludarabine in the treatment of B-cell chronic lymphocytic leukemia (B-CLL) patients who have received at least one prior therapy.

Treatments will be administered on a 28-day cycle for 4-6 cycles, with an evaluation during Cycle 4 to permit re-staging. Alemtuzumab and fludarabine will be administered on Days 1-5 of each cycle. Patients will be assessed for response at the time of re-staging at Cycle 4 and at the end of Cycle 6. At the time of the re-staging, patients achieving a Partial Remission (PR) or Stable Disease (SD) will be given an additional 2 cycles of treatment and patients demonstrating presumptive signs of a Complete Remission (CR) will receive no further treatment but will be followed for response.

Primary Outcome Measures:
  • Complete Response (CR) [ Time Frame: 28 days after last cycle with confirmation 2 months later ]
    Participants evaluated for therapeutic clinical response according to National Cancer Institute (NCI) response criteria, 28 days after 4 or 6 treatment cycles. Response confirmation involved bone marrow biopsy and aspirate performed 2 months after final treatment. CR requires for at least 2 months: no lymphadenopathy, hepatomegaly, splenomegaly or constitutional symptoms; normal complete blood count (CBC); confirmed by bone marrow aspirate and biopsy 2 months later with lymphocytes <30% of nucleated cells and procedure repeated in 4 weeks if hypocellular.


Secondary Outcome Measures:
  • Overall Response (OR) [ Time Frame: 28 days after last cycle with confirmation 2 months later ]
    Participant had either complete response (CR) or partial response (PR) at 28 days after last treatment cycle (date of OR) and at Months 2 follow-up. PR requires for at least 2 months: 50% decrease from Baseline in peripheral blood lymphocytes, lymphadenopathy, liver/spleen size, presence or absence of constitutional symptoms; plus ≥1 of the following: ≥1500/μL polymorphonuclear leukocytes, >100000/μL platelets, >11.0 g/dL hemoglobin, or 50% improvement from Baseline for these parameters without transfusions, nodular CR or persistent anemia/thrombocytopenia unrelated to disease.

  • Overall Survival (OS) [ Time Frame: 1 year after start of treatment ]
    Percentage of participants alive 1 year after the first dose date, described as Kaplan-Meier estimate at 1 year

  • Progression-free Survival (PFS) [ Time Frame: 1 year after start of treatment ]
    Percentage of participants who survived progression-free at 1 year, described as Kaplan-Meier estimate at 1 year

  • Percentage of Participants With Overall Response at Different Observation Times [ Time Frame: from first date of confirmed response until relapse, or death, or study data cutoff date, whichever is earlier ]
    Participant had either complete response (CR) or partial response (PR) at different observation times (after 90 days; after 180 days; after 270 days). PR requires for at least 2 months: 50% decrease from Baseline in peripheral blood lymphocytes, lymphadenopathy, liver/spleen size, presence or absence of constitutional symptoms; plus ≥1 of the following: ≥1500/μL polymorphonuclear leukocytes, >100000/μL platelets, >11.0 g/dL hemoglobin, or 50% improvement from Baseline for these parameters without transfusions, nodular CR or persistent anemia/thrombocytopenia unrelated to disease.

  • Number of Participants With Minimal Residual Disease (MRD) [ Time Frame: When CR is confirmed ]
    Presence of MRD was assessed by laboratory testing of molecular responses in blood and bone marrow samples.
