Brief Summary:
The primary objectives in the dose escalation phase are to evaluate safety and pharmacokinetics (PK) in order to determine the selected dose level(s) for expansion of REGN3767 as monotherapy and in combination with REGN2810 in patients with advanced malignancies, including lymphoma. The primary objectives in the dose expansion phase are to assess preliminary anti-tumor activity of REGN3767 alone and in combination with REGN2810 (separately by cohort) as measured by objective response rate (ORR).

  • Eastern Cooperative Oncology Group performance status of 0 or 1
  • Adequate organ and bone marrow function

Key Exclusion Criteria:

  • Prior treatment with any LAG-3 targeting biologic or small molecule
  • Radiation therapy within 2 weeks prior to randomization and not recovered to baseline from any AE due to radiation
