A Study to Evaluate the Safety, Tolerability, and Efficacy of Relatlimab in Relapsed or Refractory B-Cell Malignancies

A Phase 1/2a Dose Escalation and Cohort Expansion Study of the Safety, Tolerability, and Efficacy of Anti-LAG-3 Monoclonal Antibody (Relatlimab, BMS-986016) Administered Alone and in Combination With Anti-PD-1 Monoclonal Antibody (Nivolumab, BMS-936558) in Relapsed or Refractory B-Cell Malignancies

The primary objective of this study is to characterize the safety, tolerability, dose-limiting toxicities (DLTs), and maximum tolerated dose (MTD) of relatlimab administered alone or in combination with nivolumab to subjects with relapsed or refractory B-cell malignancies. Co-primary objective is to investigate the preliminary efficacy of relatlimab in combination with nivolumab in subjects with relapsed or refractory Hodgkin lymphoma (HL), and relapsed or refractory Diffused Large B Cell lymphoma (DLBCL)

Inclusion Criteria:

• Must have histologic or cytologic confirmation of chronic lymphocytic leukemia, Hodgkin lymphoma, Non-Hodgkin lymphoma, or Multiple Myeloma and have relapsed following prior treatment or been refractory to prior treatment
• Must have progressed or been refractory to, at least one prior standard therapy, including radiation, immunomodulatory agents (eg, lenalidomide), immunotherapy, cytotoxic chemotherapy, and select antibody (anti-CD20, alemtuzumab, or anti-CD30) therapy.
• Must be more than 100 days post autologous transplant

Exclusion Criteria:

• Known or suspected central nervous system (CNS) metastases or with the CNS as the only site of active disease (controlled CNS metastases are allowed)
• Known or suspected autoimmune disease
• History of allergy to anti-PD-1 or anti-PD-L1 antibody therapy or to other monoclonal antibodies or related compounds or to any of their components
