To evaluate rates of OR, PR, and CR and CRi at 12 weeks after Day 1 of the last cycle of multi-agent therapy. ? To evaluate OR, PR, CR, and CRi rates 12 weeks after Day 1 of the last cycle of multi-agent therapy, as determined by the IRC. ? To evaluate overall survival (OS). ?

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Diagnosis of CLL that meets published diagnostic criteria (Hallek et al. 2008). Patients must have peripheral blood B-lymphocyte counts which clonally express CD5, CD19/20 and CD23 and are either kappa or lambda light-chain restricted. Pro-lymphocytes may comprise no more than 55% of total circulating lymphocytes. At initial diagnosis of CLL (ie, prior to front-line treatment), the peripheral lymphocyte count must have been >5000/mm3. Patients must meet the following criteria for relapsed or refractory CLL (per the iwCLL guidelines [Hallek et al. 2008]): -Relapsed disease: a patient who previously achieved a CR or PR, but after a period of 6 months or more demonstrates evidence of progression; -refractory disease: treatment failure or disease progression within 6 months of the last anti-leukemia therapy. |
- Diagnóstico de LLC que cumpla los criterios diagnósticos publicados (Hallek et al. 2008) - Los pacientes deben tener recuentos de linfocitos B en sangre periférica que expresen de forma clónica CD5, CD19/20 y CD23, y presentan restricción de cadenas ligeras kappa o lambda. - Los prolinfocitos no pueden comprender más del 55% de los linfocitos circulantes totales. - En el momento de diagnóstico inicial de la LLC (es decir, antes del tratamiento de primera línea), el recuento de linfocitos periféricos debe haber sido mayor de 5000/mm3. Los pacientes deben cumplir los siguientes criterios para la LLC recidivante o resistente (según las directrices del iwCLL [Hallek et al. 2008]) o Enfermedad recidivante: un paciente que logró previamente una RC o una RP, pero tras un periodo de 6 meses o más muestra signos de progresión. o Enfermedad resistente: fracaso del tratamiento o progresión de la enfermedad en el plazo de 6 meses desde el último tratamiento contra la leucemia. |
|
E.4 | Principal exclusion criteria |
Transformation of CLL to aggressive NHL (eg, Richter's transformation, prolymphocytic leukemia, or DLBCL) or CNS involvement by CLL. |
Transformación de la LLC a un LNH agresivo (p. ej.: transformación de Richter, leucemia prolinfocítica o LMDLB) o implicación del SNC por la LLC. |
