|Chronic Lymphocytic Leukaemia Small Lymphocytic Lymphoma||Drug: Rituximab Drug: Cladribine||Phase 2|
Chronic Lymphocytic Leukaemia (CLL) is a lymphoproliferative disorder characterized by the progressive accumulation of monoclonal peripheral B cells in bone marrow, peripheral blood and lymphoid tissues. Median survival is about 10 years. It is now clear that front line therapy for a patient with CLL requiring treatment should be the association of purine analogue and rituximab with or without cyclophosphamide. Concerning the choice of the purine analogue, similar results have been obtained by using cladribine instead of fludarabine. Although cladribine is less commonly used, the direct comparison between the two analogues for what concerns efficacy and toxicity, has confirmed the same profile of the two drugs. Encouraging results have been obtained using the monoclonal antibody in association with the purine analogue.
The utilization of rituximab as a maintenance therapy could improve the response in cases of persistence of minimal residual disease as well as delay the insurgence of relapses thus increasing the DFS.
The objective of this study is to confirm the efficacy of the association of R-2cda and of evaluating the efficacy of prolongation of therapy with additional infusions of Rituximab alone in increasing and prolonging the duration of the response. The results of this study will be compared with existing clinical results from a group of 42 pts already treated as standard with R-2cda without additional rituximab infusions.
Patients enrolled in the study will receive 4 cycles of R-2-CdA therapy. Patients, who achieve a partial response or complete response after the therapy with R- 2-CdA, will prolong therapy with Rituximab. The therapy will begin 3 months after the end of the induction therapy and patients will receive one administration every 2 months for a total of 8 administrations.
