Ofatumumab, Pentostatin, and Cyclophosphamide in Treating Patients With Untreated Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma
Study Details
Study Description
Brief Summary
This phase II trial studies how well giving ofatumumab together with pentostatin and cyclophosphamide works in treating patients with untreated chronic lymphocytic leukemia or small lymphocytic lymphoma. Monoclonal antibodies, such as ofatumumab, can block the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as pentostatin 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. Giving ofatumumab together with pentostatin and cyclophosphamide may be a better way to block cancer growth.

Detailed Description
PRIMARY OBJECTIVES:
-
Arm A: To assess the rate of complete response using pentostatin, cyclophosphamide, and ofatumumab in patients with previously untreated chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) requiring therapy.
-
Arm B: To assess the treatment-free survival rate at 18 months using pentostatin, cyclophosphamide, and ofatumumab induction therapy followed by ofatumumab consolidation in patients with previously untreated CLL or SLL requiring therapy.
SECONDARY OBJECTIVES:
-
Arm A and Arm B: To assess the rate of overall response in patients with previously untreated CLL or SLL requiring therapy and to determine the proportion of patients who achieve a minimal residual disease (MRD) negative state as assessed by flow cytometry in each arm independently.
-
Arm A and Arm B: To monitor and assess toxicity in patients with previously untreated CLL or SLL in each arm independently.
-
Arm A and Arm B: To determine the progression-free survival, treatment-free survival, and duration of response in each arm independently.
-
Arm A and Arm B: To determine if molecular prognostic parameters (zeta-chain-associated protein [ZAP]-70, cluster of differentiation [CD]38, cytogenetic abnormalities identified by fluorescence in situ hybridization [FISH], immunoglobulin heavy-chain variable-region [IgVH] mutation status, etc) relate to response to therapy in each arm independently.
-
Arm B: To assess the rate of complete response using pentostatin, cyclophosphamide, and ofatumumab induction followed by ofatumumab consolidation in patients with previously untreated CLL or SLL requiring therapy.
-
Arm B: To evaluate whether consolidation therapy with ofatumumab after pentostatin, cyclophosphamide, and ofatumumab (PCO) induction improves the depth of response.
TERTIARY OBJECTIVES:
-
Arm A and Arm B: To assess the complete and overall response as well as treatment free survival in each arm as compared to a historic control of patients treated with pentostatin, cyclophosphamide, and rituximab in an exploratory manner.
-
Arm A and Arm B: To assess the complete and overall response as well as treatment free survival of patients treated with PCO induction followed by ofatumumab consolidation (Arm B) as compared to patients treated with PCO induction who did not receive ofatumumab consolidation (Arm A) in an exploratory manner.
-
Arm A and Arm B: Assess the mechanisms of ofatumumab induced cell death and explore methods to enhance ofatumumab cytotoxicity.
OUTLINE: Patients are assigned to 1 of 2 treatment arms.
ARM A (closed to accrual as of 8/23/2011): Patients receive induction therapy comprising ofatumumab intravenously (IV) on day 1 (days 1-2 of course 1 only), pentostatin IV over 30 minutes on day 1, and cyclophosphamide IV over 30 minutes on day 1. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive induction therapy as in Arm A. Patients then receive consolidation therapy comprising ofatumumab IV on day 1. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 90 days for 1 year.

Outcome Measures
Primary Outcome Measures
- Arm A: Percentage of Complete Responses [7 months]
In Arm A: PCO, the primary endpoint of this trial is the percentage of complete responses. The NCI Working Group criteria was used to assess response to therapy: A Complete Response (CR) is briefly defines as the absence of lymphadenopathy, no heptomegaly nor splenomegaly, neutrophils greater than 1500/ul, platelets > 100,000/ul, hemoglobin >11.0 gm/dl, and peripheral blood lymphocytes <4000uL.
- Arm B: Treatment-free Survival at 18 Months [18 months]
The primary endpoint Arm B: PCO+O is treatment-free survival rate at 18 months. An event for treatment-free survival will be defined as initiation of subsequent therapy for CLL or death due to any cause. All patients meeting the eligibility criteria who have signed a consent form and have begun treatment will be evaluable for event-free survival at 18 months. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Exact binomial 95% confidence intervals for the true success proportion will be calculated.
Secondary Outcome Measures
- Overall Response Rate [14 months]
The overall response rate will be estimated by the total number of complete or partial responses (CCR, CR, CRi, nPR, or PR) divided by the total number of evaluable patients. Responses will be evaluated using NCI Working Group criteria. Minimum requirements for a Partial Response (PR) requires: 50% decrease in peripheral blood lymphocyte count from the baseline 50% reduction in the sum of the products of the largest measured node or nodal masses on physical examination. 50% reduction in size of liver and/or spleen 50% improvement in neutrophils, platelets and hemoglobin
- Depth of Response After Ofatumumab Consolidation [14 months]
The proportion of patients with an improvement in depth of response with the addition of ofatumumab consolidation after PCO induction will be estimated by the number of patients with improvement in response from the time of response evaluation at the completion of PCO to the time of response evaluation at the completion of ofatumumab consolidation divided by the total number of evaluable patients. The hierarchy for depth of response will be in the following increasing order: SD, PR, nPR, CR/CRi with MRD+, CR/CRi with MRD-. An improvement in depth of response will be defined as an improvement of at least one level in the hierarchy. Exact binomial 95% confidence intervals for the true overall improvement rate will be calculated.
- Treatment-free Survival [up to 5 years from registration]
Treatment-free survial is defined as the time from registration to the date of initiation of subsequent treatment for CLL or death due to any cause. The distribution of treatment-free survival will be estimated using the method of Kaplan-Meier.
