Study Summary

Safety Run In Phase: To evaluate the safety and tolerability of epcoritamab in combination with other agents Expansion Phase: To Assess the preliminary anti-tumor activity of epcoritamab in combination with other agents To evaluate the safety, tolerability, PK, pharmacodynamics/biomarkers, immunogenicity, and preliminary efficacy of epcoritamab in combination with other standard of care (SOC) agents in subjects with B-NHL. Step-up dosing and corticosteroids during cycle 1 were used to mitigate cytokine release syndrome (CRS). Responses were evaluated by position emission tomography–computed tomography per the 2014 Lugano classification criteria To present preliminary results from arm 2 of this trial, which is evaluating epcoritamab in combination with R2 in pts with R/R FL. To present data from arm 1 of this trial, in which epcoritamab in combination with R-CHOP is evaluated in pts with previously untreated high-risk DLBCL. PET-CT was used to assess response To present results for a larger cohort with longer follow-up. To evaluate epcoritamab SC + R-mini-CHOP in 1L DLBCL. A safety run-in was conducted to confirm acceptability of the safety profile. To report initial data from arm 8 of the phase 1/2 EPCORE™ NHL-2 study evaluating epcoritamab SC + R-mini-CHOP in 1L DLBCL. To report updated data from epcoritamab in combination with rituximab, dexamethasone, cytarabine, and oxaliplatin or carboplatin (R-DHAX/C) in pts with R/R DLBCL eligible for HDT-ASCT, including high-risk pts (progressed within 12 mo of initial tx or primary refractory), from EPCORE™ NHL-2 To present data from EPCORE™ NHL-2 (phase 1/2; NCT04663347), with longer follow-up for epcoritamab + R2 in 1L FL (arm 6) and the first disclosure for epcoritamab maintenance in patients (pts) with FL in CR or partial response (PR) after 1–2 lines of standard of care (SOC) tx (arm 7). To report additional efficacy and safety results of epcoritamab + GemOx in difficult-to-treat R/R DLBCL (EPCORE™ NHL-2 phase 1/2 trial, NCT04663347). Methods: Adults with R/R CD20+ DLBCL who failed or were ineligible for autologous stem cell transplant (ASCT) enrolled to To present long-term follow-up beyond 2 y and minimal residual disease (MRD) analysis for the first time. MRD analysis was performed on peripheral blood mononuclear cell samples collected at prespecified time points (clonoSEQ® assay, Adaptive Biotechnologies) and quantified as tumor clones detected per 1 x 106 nucleated cells. To report updated results with longer follow-up from arm 8 of the EPCORE® NHL-2 trial evaluating epcoritamab + R-mini-CHOP in this population. To present long-term follow-up beyond 2 y, including in subgroups, and minimal residual disease (MRD) analyses for the first time To present initial results from arm 3 of the ongoing phase 1b/2 EPCORE NHL-2 trial evaluating fixed-duration epcoritamab + BR in 1L FL, including T-cell pharmacodynamics with this novel combination. To evaluate the safety and tolerability of epcoritamab in combination with other agents Expansion Phase: Arms 1-6 and 8-10: Assess the preliminary anti-tumor activity of epcoritamab in combination with other agents Arm 7: Evaluate the safety and tolerability of epcoritamab following standard of care (SOC) Efficacy by baseline (BL) bulky disease (BD) status (≥ 7 cm [n = 6] vs. < 7 cm [n = 19]) was evaluated. To report the first disclosure of circulating tumor DNA (ctDNA) over time to provide insights into MRD kinetics for pts treated with epcor + GemOx. MRD was assessed using the Avenio ctDNA assay with a cutoff of negativity defined as < 1 mutant molecule/ml. MRD-evaluable pts required a baseline and ≥ 1 on-tx MRD result and MRD positivity at C1D1. Best overall response and progression-free survival (PFS), were assessed by independent review committee per Lugano criteria. To report efficacy and safety from a 3-year follow-up of patients who received epcoritamab + R-CHOP in the EPCORE NHL-2 trial. To report long term durability data from this cohort after >2 y of follow-up
