Trial Outcomes & Findings for Phase 2 Study of Bexxar in Relapsed/Refractory DLCL (NCT NCT00490009)

NCT ID: NCT00490009

Last Updated: 2017-03-30

Results Overview

Clinical response rate for all participants, reported as the sum of the numbers of patients achieving complete response (CR, complete disappearance of all lesions); functional CR (fCR, minimal residual disease but clear of disease by positron emission tomography (PET)-scan); or partial response (PR, ≥ decrease in size of lesions and negative for active disease by PET-scan). Progressive disease (PD, advancing cancer) or stable disease (not CR, fCR, or PD) not included as Clinical Response.

Bexxar is a radioimmunotherapeutic drug, an antibody that specifically attaches to the CD20 antigen, which is present on the surfaces of B cells and B cell lymphoma cells. Bexxar is patient specific: 75 cGy whole body patients with platelet count of 150,000/mm³ and 65 cGy for patients with platelet count less than 150,000/mm³, IV
