Everolimus and Alemtuzumab in Treating Patients With Recurrent Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma

Phase 1

Completed

Conditions: Lymphocytic Leukemia

Interventions: Drug: alemtuzumab
Drug: everolimus

Registration Number: NCT00935792

Lead Sponsor: Mayo Clinic

Brief Summary: RATIONALE: Everolimus may stop the growth of cancer cells by blocking some of the signaling molecules needed for cell growth. Monoclonal antibodies, such as alemtuzumab, can bind to and kill malignant lymphocytes.

PURPOSE: This phase I/II trial is studying the side effects and best dose of everolimus when given together with alemtuzumab and will see how well they work in treating patients with recurrent chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL).

Detailed Description: PRIMARY OBJECTIVES: I. Test the safety and tolerability of the combination of everolimus and alemtuzumab. (Phase I) II. Determine the maximum tolerated dose of everolimus in this combination. (Phase I) III. Assess the rate of overall responses in patients with relapsed/refractory CLL to treatment with the maximum tolerated dose of everolimus together with a standard dose of alemtuzumab using conventional NCI-WG 1996 response criteria. (Phase II) IV. To assess the complete responses to this combination regimen using conventional NCI-WG 1996 criteria and an expanded definition of response, including CT scans of chest-abdomen-pelvis, immunohistochemical analysis for residual disease in the bone marrow, and sensitive flow cytometry for minimal residual disease in patients in complete clinical remission. V. To monitor and assess toxicity of this regimen. SECONDARY OBJECTIVES: I. To determine the overall and progression-free survival, duration of response, and time to next treatment. II. To assess the correlation between the individual prognostic markers (17p-, p53 gene mutations, 11q-, unmutated VH gene, use of VH3-21, ZAP70+, CD38+, CD49d, B2 microglobulin) and clinical outcome. III. Serial measurement of clinical status and lymphocyte counts to test the rate of reduction in CLL tumor burden. TERTIARY OBJECTIVES: I. Determine the effect of everolimus on the sensitivity of CLL cells to alemtuzumab CDC and ADCC. II. Determine the effect of everolimus on the CLL cell-stroma interaction. III. Detail the in vivo effect of the everolimus-alemtuzumab regimen on critical aspects of the immune system in CLL. OUTLINE: This is a phase I, dose escalation study of everolimus followed by a phase II study. Patients receive oral everolimus thrice weekly for 9 weeks and alemtuzumab subcutaneously thrice weekly for 7 weeks in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed periodically for up to 5 years. PROJECTED ACCRUAL: A total of 44 patients will be accrued for this study.

Primary Outcome Measures

Name	Time	Method
Clinical Response (Complete or Partial Remission)	After 2 courses of treatment	CR requires all of the following for a period of at least 2months:Absence of lymphadenopathy.No hepatomegaly or splenomegaly.Absence of constitutional symptoms.• Neutrophils\>1500/ul•Platelets\>100,000/ul • Hemoglobin \>11.0gm/dl• Peripheral blood lymphocytes \<4000/uLBonemarrow. normocellular with\<30%of nucleated cells being lymphocytes.PR requires two for 2+months.≥50%decrease in peripheral blood lymphocyte count from the pretreatment baseline value.≥ 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.≥ 50%reduction in size of liver and/or spleen noting the maximal distance below the respective costal margins of palpable hepatosplenomegaly during rest.Neutrophils\>1500/ul or50%improvement over baseline. Platelets\>100,000/ul or50%increase over baseline. Hemoglobin\>11.0 gm/dl or50%increase over baseline without transfusions
Number of Participants With Dose-Limiting Toxicities	1 Month	The maximum tolerated dose is the dose level below the lowest dose that induces dose-limiting toxicity in at least one-third of patients. A total of 6 patients treated at the MTD will be sufficient to identify common toxicities at the MTD. Dose-limiting toxicity will be defined as an adverse event attributed (definitely, probably, or possibly) to the study treatment and meeting the following criteria. Hematologic: ANC ≤ 0.3 x 109/L or platelet count \< 10 x 109/L Other nonhematologic: ≥grade 3 as per NCI Common Terminology Criteria for Adverse Events v3.0 except for fatigue, hyperlipidemia, and hyperglycemia.
Test the Safety and Tolerability of the Combination of Everolimus and Alemtuzumab.	Up to 12 months past final treatment	The number and severity of all adverse events will be tabulated and summarized in this patient population. The grade 3+ adverse events will also be described and summarized in a similar fashion. This will provide an indication of the level of tolerance for this treatment combination in this patient group. Below is the number of patients that experienced a grade 3+ Adverse event that was at least possibly related to Treatment.

Secondary Outcome Measures

Name	Time	Method
Progression-free Survival	up to 5 years	Progression-free survival time is defined as the time from registration to progression or death due to any cause. The distribution of progression-free survival will be estimated using the method of Kaplan-Meier
Duration of Response	up to 5 years	Duration of response is defined for all evaluable patients who have achieved a clinical response as the date at which the patient's objective status is first noted to be a Complete Response or Partial Response to the earliest date progression is documented. The distribution of duration of response will be estimated using the method of Kaplan-Meier
Survival Time	up to 5 years	Survival time is defined as the time from registration to death due to any cause. The distribution of survival time will be estimated using the method of Kaplan-Meier
Time to Subsequent Therapy	up to 5 years
