study evaluating the effect of r-mabhdi in lymphocytic predominant hodgkin's lymphoma

Conditions: Hodgkin's Lymphoma

Summary: objective: the primary objective of the study is to evaluate the effect of r-mabhdi in patients with late stage, widespread stage and recurrent lymphocytic predominant hodgkin's lymphoma. the hypothesis is that the combination of r-mabhdi with the standard abvd therapy in patients with late stage (stage iii and stage iv) and recurrent stage lymphocytic predominant hodgkin's lymphoma will have a favorable outcome on the response and progress free survival. the study is also aimed at evaluating the safety of r-mabhdi . the aim of the study is to test this hypothesis by evaluating the clinical outcome in 1200 patients receiving combination of r-mabhdi once a week for 8 weeks and abvd therapy every other week for 12 treatments.
