ABSTRACT
Chronic lymphocytic leukemia (CLL) is one of the most common haematological malignancies exhibiting remarkable heterogeneity in clinical course. Rituximab added to standard chemotherapy has been proven to increase response rate and eventually survival among previously untreated CLL patients. CILI was an open-label, non-randomized, single arm, multicentric, observational study aimed to collect real-life effectiveness data for rituximab used according to the current label in combination with standard chemotherapy in previously untreated CLL patients. Overall response rates (ORR) in the entire study population as well as in various subgroups were estimated. Adverse events were recorded during the entire course of the study. A total number of 150 patients were enrolled by 15 Hungarian study sites. Out of these, 82 patients received 6 cycles of rituximab containing treatment. Overall response rates of 88.24% (CI95% 81.6-93.12%) and 94.59% (CI95% 86.73-98.51%) were recorded in the intent-to-treat (ITT) and per-protocol (PP) populations, respectively. In both study populations, somewhat higher ORR was observed in patients aged ≥65 years. Subgroups defined according to either chromosomal aberrations (presence of 11q and 17p deletions) showed apparently high ORRs, though these rates were most probably biased by low patient numbers. 144 adverse events were reported during the study, of which 15 AEs were considered to be related to the administration of rituximab. Analyses of the efficacy variables have revealed comparable results to those previously reported by controlled clinical trials.
