• Status: Active, not recruiting
• Trial end date: 2021-12-01

• Participant gender: All

Summary

The aim of the trial is to test whether adding 6 injections of rituximab to standard "Lymphome malin B" LMB chemotherapy regimen improves the Event Free Survival (EFS) compared with LMB chemotherapy alone in children / adolescents with advanced stage B-cell Non-Hodgkin Lymphoma (NHL) / B-Acute Leukemia (B-AL)(stage III and LDH > Nx2, any stage IV or B-AL).

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

• Treatments: Cyclophosphamide; Cytarabine; Doxorubicin; Liposomal doxorubicin; Methotrexate; Rituximab; Vincristine
