Non-Hodgkin's Lymphoma
Chronic Lymphocytic Leukemia
Drug: REGN1979 multiple dose levels
Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Endpoint Classification: Safety Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: An Open-Label, Multi-Center Phase 1 Study to Investigate the Safety and Tolerability of REGN1979, an Anti-CD20 x Anti-CD3 Bispecific Monoclonal Antibody, in Patients With CD20+ B-Cell Malignancies Previously Treated With CD20-Directed Antibody Therapy
