Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of the study is to assess safety, tolerability and dose limiting toxicity (DLT) of: • Single-agent REGN2810 in patients with lymphoma (B-cell non-Hodgkin lymphoma [B-NHL] and Hodgkin's lymphoma [HL]) • Combination REGN1979 and REGN2810 in patients with B NHL ;Secondary Objective: The secondary objectives of the study are: • To determine a recommended dose for: o cemiplimab as a single-agent in patients with lymphoma (B-NHL and HL) o REGN1979 and cemiplimab administered in combination in patients with B-NHL. • To characterize the pharmacokinetic (PK) profile of cemiplimab when administered as a single agent and of cemiplimab and REGN1979 when administred in combination • To assess the immunogenicity of cemiplimab when administered alone and the immunogenicity of cemiplimab and REGN1979 when administred in combination • To study the preliminary antitumor activity of cemiplimab as a single agent and of the combination of cemiplimab and REGN1979 in specific indications, as measured by overall response rate, minimal residual disease (MRD) in patients with bone marrow disease at baseline, duration of response and median progression-free survival and rates at 6 and 12 months;Primary end point(s): Safety;Timepoint(s) of evaluation of this end point: From informed consent form signature until 30 day post last dose of study drug

Secondary

MeasureTime frame
Secondary end point(s): • PK of single agent cemiplimab , and PK of REGN1979 and cemiplimab when given in combination • Antitumor activity: o Overall response rate (ORR) as per applicable response criteria for the indication o Duration of response, and PFS at 6 and 12 months o Minimal residual disease (MRD) for patients with bone marrow involvement at baseline • Pharmacodynamic measures including: o Cytokine profiling o Peripheral blood B-cell and T-cell subsets and immune phenotyping o Analysis of PD-1 receptor occupancy of circulating T-cells o Changes in gene expression in peripheral blood o Serum immunoglobulin ;Timepoint(s) of evaluation of this end point: each of the secondary endpoints is being assessed at specific time points as outlined in protocol
