Brief Summary:

RATIONALE: Drugs used in chemotherapy, such as pentostatin, cyclophosphamide, and lenalidomide work in different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies, such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining chemotherapy with monoclonal antibody therapy may kill more tumor cells.

PURPOSE: This phase II trial is studying how well pentostatin, cyclophosphamide, rituximab, and lenalidomide work in treating patients with relapsed or refractory B-cell chronic lymphocytic leukemia.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 102 participants
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Trial of Pentostatin, Cyclophosphamide and Rituximab (PCR) Followed by Campath-1H for Previously Treated Relapsed or Refractory Patients With Chronic Lymphocytic Leukemia
Actual Study Start Date : December 16, 2004
Actual Primary Completion Date : August 28, 2013
Actual Study Completion Date : May 6, 2018


Arm Intervention/treatment
Experimental: Arm A (PCR)

Treatment consisted of 6 cycles of pentostatin, cyclophosphamide, and rituximab (PCR) given every 28 days.

Rituximab administered as follows: For the first infusion, all patients receive 100 mg dose (regardless of weight/BSA). For subsequent infusions, all patients receive rituximab 375 mg/m2.

Pentostatin and cyclophosphamide administered as follows: Pentostatin given at 4 mg/m2 either as an IV push or IV over 10-30 minutes in 250 mL NS or D5W on day 1 every 4 weeks of cycles 1-6. Cyclophosphamide given at 600 mg/m2 IV over 30-60 minutes in 250 mL NS on day 1 every 4 weeks of cycle 1-6.

Biological: rituximab
Other Name: Rituxan

Drug: cyclophosphamide
Other Name: Cytoxan

Drug: pentostatin
Other Names:
  • deoxycoformycin
  • Nipent

Experimental: Arm B (Alemtuzumab: CR, nPR)
Patients who achieved a confirmed CR or nPR, were registered to receive Alemtuzumab (Arm B). When the patient was registered to Arm B, the drug was administered three times a week for four weeks. The dose was 30 mg per dose. A twelve-week treatment-free period had to elapse before CAMPATH-1H began following completion of PCR for Arm B patients
Drug: Alemtuzumab
Other Names:
  • Campath
  • Campath-1H

Experimental: Arm C (Alemtuzumab: PR, <PR, PD)
For those patients not achieving a CR or nPR (thus patients either achieved PR, SD, or PD), Alemtuzumab (Arm C) was administered three times a week for eighteen weeks at a dose of 30 mg TIW. For PR, SD and PD patients, the timing of CAMPATH-1H was left to the discretion of the investigator, and treatment could begin earlier but no less than two weeks and no longer than eight weeks after the completion of the last PCR course. Patients determined to have PD during treatment with PCR did not need to complete all 6 cycles of PCR to go on to Arm C, however, completing a minimum of 2 cycles was required.
Drug: Alemtuzumab
Other Names:
  • Campath
  • Campath-1H




Primary Outcome Measures :
  1. Response Rate [ Time Frame: 8 weeks after Cycle 6 ]
    Proportion with response (CR, nPR, PR)

  2. Molecular Complete Remission (MCR) Rate [ Time Frame: 3 months post alemtuzumab ]
    Proportion of patients who have MCR (clinical CR with flow negative and RT-PCR negative)


Secondary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: Up to 5 years from registration ]
    OS is defined as the time from registration until death from any cause.

  2. Progression-free Survival (PFS) [ Time Frame: Up to 5 years from registration ]
    PFS is defined as the time from registration until induction failure, institution of non-protocol therapy, relapse or death from any cause in the absence of relapse.
