Activity & Safety Study of Lenalidomide & Rituximab as Non-chemotherapy Based Therapy on Chronic Lymphocytic Leukemia (LLC-LENAR-08)
Phase I Study of the Activity and Safety of Lenalidomide and Rituximab as Non-chemotherapy Therapy for Patients With Recurrent and Refractory Chronic Lymphocytic Leukemia
The rationale for combining lenalidomide with rituximab derives from preclinical observations suggesting that lenalidomide may enhance the ADCC (antigen-dependent cellular cytotoxicity) triggered by monoclonal antibodies such as rituximab. Lenalidomide augments NK cytotoxicity by increasing CD56dimCD3 subset, in addition to inducing IL-2 in T cells. These results provide the cellular and molecular basis for the use of lenalidomide as an adjuvant in immunotherapeutic strategies of monoclonal antibodies (mAb)-based therapies. The combination lenalidomide-rituximab was tested in lymphoma cell lines but not specifically on CLL cell lines. However the observed synergism was attributed to NK cells expansion, thus lending support to the notion that this synergism may operate in other B-cell lymphoproliferative malignancies.
The objective was to develop a non-cytotoxic and effective treatment for CLL that would fulfill an unmet medical need, as a significant proportion of CLL patients are elderly and frail. These patients experience an excess in chemotherapy induced toxicity, often preventing the completion of the planned treatment.

Eksperimentel: Lenalidomida, Rituximab
Phase I: Lenalidomide will be administered from day 1 to 21 of 28 days cycles, escalating doses (from 2,5mg to 25 mg).Rituximab dose will be administered at the standard (375 mg/m2 in the first cycle and 500 mg/m2 in successive cycles).
|
Lenalidomide: Oral use. It will be administered from day 1 to 21 of 28 days cycles in a total of 6 cycles. Rituximab, intravenous use. The dose will be administered at the standard (375 mg/m2 in the first cycle and 500 mg/m2 in successive cycles). In the first cycle Rituximab will be administered in two divided doses:100mg/m2 total on day 1 and the rest up to 375mg/m2 on day 2. If lenalidomide treatment starts on day 1, Rituximab will be administered, in this first cycle, on days -2 (100 mg/m2) and -1 (275 mg/m2). In the second and subsequent cycles, 500 mg/m2 of Rituximab will be administered on day -1.
