Imprime PGG, Alemtuzumab, and Rituximab in Treating Patients With High Risk Chronic Lymphocytic Leukemia
Study Details
Study Description
Brief Summary
RATIONALE: Monoclonal antibodies, such as alemtuzumab and rituximab, can kill chronic lymphocytic leukemia (CLL) cells and are effective therapies for this disease. Biological therapies, such as Imprime PGG (poly-(1-6)-beta-glucotriosyl-(1-3)-beta-glucopyranose), may stimulate the immune system in different ways and help monoclonal antibodies kill CLL cells. Giving PGG beta-glucan together with alemtuzumab and rituximab could make therapy with monoclonal antibodies, such as alemtuzumab and rituximab, more effective.
PURPOSE: This phase I/II trial is studying the side effects and best dose of PGG beta-glucan when given together with alemtuzumab and rituximab and to see how well it works in treating patients with earlier stage high-risk chronic lymphocytic leukemia.

Detailed Description
PRIMARY OBJECTIVES:
- Determine the maximum tolerated dose of PGG beta glucan in combination with alemtuzumab and rituximab. (Phase I) II. Assess the rate of complete response of patients with high-risk, early-intermediate stage CLL who are treated with alemtuzumab, rituximab, and PGG beta glucan before meeting standard National Cancer Institute-International Workshop on Chronic Lymphocytic Leukemia (NCI-IWCLL) criteria (Hallek, Cheson et al. 2008) for treatment. (Phase
SECONDARY OBJECTIVES:
-
To monitor and assess toxicity of this regimen. II. Clinical evaluation of toxicity. III. Serial monitoring of cytomegalovirus (CMV) viral load by polymerase chain reaction (PCR).
-
To assess the rate of overall response in CLL patients using this treatment regimen.
-
To determine time to progression, time to next treatment, and duration of response in CLL patients using this treatment regimen.
TERTIARY OBJECTIVES:
-
To assess the correlation between the individual prognostic markers (17p-, 11q-, unmutated VH gene, use of VH3-21, ZAP70+, CD38+) and clinical outcome.
-
To assess response to this combination regimen using an expanded definition of response, including bone marrow studies with immunohistochemical studies for residual CLL cells and sensitive flow cytometry for minimal residual disease in patients in complete clinical remission.
OUTLINE: This is phase I, dose-escalation study of PGG beta-glucan followed by a phase II study.
Patients receive PGG beta-glucan intravenously (IV) over 2-4 hours on days 1, 5, 10, 17, 24, and 31; alemtuzumab subcutaneously (SC) on days 3, 4, 5, 8, 10, 12, 15, 17, 19, 22, 24, 26, 29, 31, and 33; and rituximab IV on days 10, 17, 24, and 31. Treatment continues in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up monthly for 3 months, every 3 months for 1 year, and then every 6 months for 5 years.

Outcome Measures
Primary Outcome Measures
- Maximum Tolerated Dose (MTD) of PGG Beta Glucan in Combination With Alemtuzumab and Rituximab Assessed by Analyzing the Number of Dose-limiting Toxicity Events (Phase I) [First cycle of treatment (35 days)]
MTD is defined as the dose level below the lowest dose that induces dose-limiting toxicity (DLT) in at least one-third of patients (at least 2 of a maximum of 6 new patients). A total of 6 patients treated at the MTD will be sufficient to identify common toxicities at the MTD. Three patients will be treated at a given dose level combination for at least 5 weeks to assess toxicity. If dose-limiting toxicity (DLT) is not seen in any of the 3 patients, 3 new patients will be accrued and treated at the next higher dose level. If DLT is seen in 2 or 3 of 3 patients treated at a given dose level, then the next 3 patients will be treated at the next lower dose level, if only 3 patients were enrolled and treated at this lower dose level. We tabulate the number of patients reporting a DLT.
- Proportion of Complete Responses (Dose Level 2) [3 months after the completion of treatment, up to 5 years]
The number of patients that demonstrate a Complete Response (CR) during treatment on Dose Level 2 divided by the number of eligible patients starting Dose Level 2 treatment. A CR requires all of the following for a period of at least 2 months: Absence of lymphadenopathy by physical examination, no hepatomegaly or splenomegaly, absence of constitutional symptoms, neutrophils >1500/ul, Platelets >100,000/ul, Hemoglobin >11.0 gm/dl, Peripheral blood lymphocytes <4000/uL.
Secondary Outcome Measures
- Overall Response Rate (Dose Level 2) [3 months after the completion of treatment, up to 5 years]
Overall response rate was estimated by the total number of patients receiving Dose Level 2 reporting complete responses or partial responses (CR or PR) divided by the total number of evaluable patients that started Dose Level 2 treatment. A COMPLETE RESPONSE (CR) requires all of the following for a period of at least 2 months: Absence of lymphadenopathy by physical examination, no hepatomegaly or splenomegaly, absence of constitutional symptoms, neutrophils >1500/ul, Platelets >100,000/ul, Hemoglobin >11.0 gm/dl, Peripheral blood lymphocytes <4000/uL. A PARTIAL RESPONSE (PR) requires the patient exhibits at least two of the features: ≥ 50% decrease in peripheral blood lymphocyte count from baseline, ≥ 50% reduction in the sum of the products of the maximal perpendicular diameters of the largest measured node or nodal masses in the right and left cervical, axillary, and inguinal lymph node regions on physical examination.
- Time to Disease Progression [Up to 5 years]
Time to disease progression is defined as the time from registration to the earliest date of documentation of disease progression. If a patient dies without a documentation of disease progression, the patient will be considered to have had tumor progression at the time of their death unless there is sufficient documented evidence to conclude no progression occurred prior to death. The distribution of time to disease progression will be estimated using the method of Kaplan-Meier.
- Duration of Response for All Evaluable Patients Who Have Achieved an Objective Response [Up to 5 years]
Duration of response is defined for all evaluable patients who have achieved an objective response as the date at which the patient's objective status is first noted to be either a CR or PR to the earliest date progression is documented. The distribution of duration of response will be estimated using the method of Kaplan-Meier.
- Time to Subsequent Therapy [Up to 5 years]
Time to subsequent therapy is defined to be the time from the end of active treatment date to the date subsequent therapy is initiated. The distribution of time to subsequent therapy will be estimated using the method of Kaplan-Meier.
- Number of Participants With Grade 3+ Adverse Events [up to 5 years of treatment]
Adverse events were collected at the end of each cycle according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. The number of grade 3+ events at least possibly related to treatment are recorded. For a complete set of all recorded adverse events, please see the Adverse Events section of this report.
