A Phase 3 Trial of Epcoritamab vs Investigator's Choice Chemotherapy in R/R DLBCL

Phase 3
Active, not recruiting
Conditions
Diffuse Large B-cell Lymphoma
Interventions
Drug: Investigator's Choice Chemotherapy
Registration Number
NCT04628494
Lead Sponsor
Genmab
Brief Summary

The purpose of this trial is to find out if epcoritamab, also known as EPKINLY™ and GEN3013, is safe and works well as treatment for patients with diffuse large B-cell lymphoma (DLBCL) that are not responding to treatment, have grown in size, or have come back following treatment with at least 1 prior systemic cancer therapy. All participants in this trial will be randomly assigned to receive either epcoritamab or a pre-specified investigator's choice (standard of care) chemotherapy (either rituximab + gemcitabine + oxaliplatin \[R-GemOx\], or bendamustine + rituximab \[BR\]). Participants must have failed or be ineligible to receive an autologous stem cell transplant (ASCT).

Epcoritamab will be injected under the skin. Investigator's choice chemotherapy will be given intravenously.

Trial details include:

* The trial duration will be up to 5 years after last participant is randomized.

* All trial participants have a 21-day screening period, a treatment period, and a follow-up period that continues until death.

* The estimated trial duration for an individual subject depends upon the treatment arm assigned:

* Participants who receive epcoritamab will have 28-day treatment cycles. Epcoritamab will be given once weekly for the first 3 months, then every other week for 6 months, then every 28 days until lymphoma progression or unacceptable adverse events.

* Participants who receive investigator's choice (standard of care) chemotherapy will receive treatments either:

* R-GemOx: On Day 1 (or Day 1 \& Day 2), and Day 15 (or Day 15 \& Day 16) every 28 days, for up to 4 months; or

* BR: On Day 1 and Day 2 every 3 weeks for up to 4.5 months.

Detailed Description

The trial is an open label, multi-center, global phase-3 randomized trial of epcoritamab. The goal of this randomized trial is to evaluate the efficacy of epcoritamab (GEN3013, DuoBody®-CD3xCD20) compared to investigator's choice of chemotherapy, in patients with relapsed, refractory DLBCL who have failed or are ineligible for high-dose chemotherapy and autologous stem cell transplant (HDT-ASCT). No change in chemotherapy is permitted for participants during the treatment phase of the trial.

Primary Outcome Measures
NameTimeMethod
Overall Survival (OS)throughout the study and up to 5 years following the last patient first dose

OS is calculated as the time from first dose to death date or last date known to be alive.

Secondary Outcome Measures
NameTimeMethod
Complete Response (CR)throughout the study and up to 5 years following the last patient first dose

CR rate is calculated as the proportion of subjects achieving a complete response. Response is determined by the Lugano criteria and LYRIC.

Duration of Response (DOR)throughout the study and up to 5 years following the last patient first dose

DOR is calculated as the time from initial response (CR or PR) to date of progression or death, whichever is earlier. Response and progression are determined by the Lugano criteria and LYRIC.

Time to Response (TTR)throughout the study and up to 5 years following the last patient first dose

TTR is calculated as the time from randomization to date of initial response (CR or PR) among responders only. Response is determined by the Lugano criteria and LYRIC.

Progression Free Survival (PFS)throughout the study and up to 5 years following the last patient first dose

PFS is calculated as the time from randomization to the date of disease progression or death, whichever is earlier. Progression is determined by the Lugano criteria and LYRIC.

Incidence and severity of adverse events (AEs)throughout the study and up to 5 years following the last patient first dose

identify patterns of incidence in adverse events, with particular emphasis on pre-defined adverse events of special interest

Anti-epcoritamab antibody responsethroughout the study and up to 5 years following the last patient first dose

calculate incidence of antibody response to epcoritamab in relation to dosing

Incidence and severity of changes in laboratory valuesthroughout the study and up to 5 years following the last patient first dose

Clinical laboratory parameters assessed: hematology, chemistry, coagulation, tumor lysis, immunoglobulins, and urinalyses

Incidence of dose interruptions and delaysthroughout the study and up to 5 years following the last patient first dose

calculate incidence and present the occurrence of dose modifying toxicities by cycles and overall

Overall Response Rate (ORR)throughout the study and up to 5 years following the last patient first dose

ORR is calculated as the proportion of subjects achieving a complete response or partial response. Response is determined by the Lugano criteria and LYRIC.

Rate and duration of minimal residual disease (MRD) negative statusup to 5 years after randomization of the last patient

Compare other measures of efficacy to SOC - MRD negativity rate, defined as the proportion of subjects who have at least one negative MRD sample at any time point prior to start of subsequent anti-lymphoma therapy

Time to next anti-lymphoma therapy (TTNT)throughout the study and up to 5 years following the last patient first dose

TTNT is calculated as the time from randomization to date of initiation of new anti-lymphoma therapy.

Changes in lymphoma symptoms as measured by the Functional Assessment of Cancer Therapy - Lymphoma (FACT-Lym)throughout the study and up to 5 years following the last patient first dose

monitor change from baseline in health-related quality of life over time and in relation to treatment
