Condition or disease | Intervention/treatment | Phase |
---|---|---|
Diffuse Large B-cell Lymphoma High-grade B-cell Lymphoma Primary Mediastinal Large B-cell Lymphoma Follicular Lymphoma Mantle Cell Lymphoma Small Lymphocytic Lymphoma Marginal Zone Lymphoma | Biological: Epcoritamab | Phase 1 Phase 2 |
The purpose of the dose-escalation part of the trial is to determine the maximum tolerated dose (MTD) and the recommended Phase-2 dose (RP2D), as well as to establish the safety profile of epcoritamab in patients with relapsed, progressive or refractory B-Cell Lymphoma.
In the expansion part, additional patients will be treated with epcoritamab, at the RP2D and the purpose is to further explore and determine the safety and efficacy of epcoritamab.

- Escalation part: Incidence of Dose Limiting Toxicities (DLTs) [ Time Frame: Assessed during the first cycle (28 days) in each cohort. ]To determine the RP2D and the MTD, if reached.
- Escalation part: Incidence and severity of Adverse Events (AEs) [ Time Frame: From first dose until the end of the safety follow-up period (4 weeks after last dose) ]Treatment-emergent AEs (TEAEs)
- Expansion part: Objective Response Rate (ORR) [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Defined as proportion of participants who have a partial or complete response (PR or CR) following treatment with epcoritamab. Determined by the Lugano response criteria, assessed by the Independent Review Committee (IRC).
- Both parts: Area-under-the-concentration-time curve from Time 0 to Time of last dose (AUClast) [ Time Frame: From first dose until treatment discontinuation, expected average of 1 year ]
- Both parts: AUC from Time 0 to Infinity (AUCinf) [ Time Frame: From first dose until treatment discontinuation, expected average of 1 year. ]
- Both parts: Maximum (peak) plasma concentration (Cmax) [ Time Frame: From first dose until treatment discontinuation, expected average of 1 year ]
- Both parts: Time to reach Cmax (Tmax) [ Time Frame: From first dose until treatment discontinuation, expected average of 1 year ]
- Both parts: Pre-dose (trough) concentrations (Cthrough) [ Time Frame: From first dose until treatment discontinuation, expected average of 1 year ]
- Both parts: Total body clearance of drug from the plasma (CL) [ Time Frame: From first dose until treatment discontinuation, expected average of 1 year ]
- Both parts: Volume of distribution (Vd) [ Time Frame: From first dose until treatment discontinuation, expected average of 1 year ]
- Both parts: Elimination half-life (t 1/2) [ Time Frame: From first dose until treatment discontinuation, expected average of 1 year ]
- Both parts: Incidence of anti-drug antibodies (ADA) [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]
- Escalation part: ORR [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Defined as proportion of participants who have a PR or CR following treatment with epcoritamab. Determined by the Lugano response criteria.
- Escalation phase: PR [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Determined by the Lugano response criteria.
- Expansion part: Time to Response (TTR) [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Defined as time to first documentation of objective tumor response (PR or better). Determined by the Lugano and LYRIC response criteria, assessed by the IRC.
- Both parts: Duration of Response (DOR) [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Defined as time from first documentation of response (CR or PR) to the date of progression of disease (PD) or death, whichever occurs earlier. Determined by the Lugano response criteria (both parts) and by the LYRIC response criteria (expansion part). Response/disease progression in the expansion part is reviewed by the IRC.
- Both parts: CR rate [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Defined as proportion of participants with CR. Determined by the Lugano response criteria (both parts) and by the LYRIC response criteria (expansion part). Response/disease progression in expansion part is reviewed by the IRC.
- Expansion part: Duration of CR (DoCR) [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Defined as time from first documentation of CR to the date of PD or death, whichever occurs earlier. Determined by the Lugano and LYRIC response criteria, assessed by the IRC.
- Both parts: Progression Free Survival (PFS) [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Defined as time to first documented PD or death due to any cause. Determined by the Lugano response criteria (both parts) and by the LYRIC response criteria (expansion part). Response/disease progression in the expansion part is reviewed by the IRC.
- Both parts: Time to next anti-lymphoma therapy (TTNT) [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Calculated as time to date of initiation of new anti-lymphoma therapy.
- Both parts: Overall Survival (OS) [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Defined as time to death.
- Expansion part: Rate and duration of Minimal Residual Disease (MRD) negative status [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Rate is defined as proportion of participants with at least one MRD- sample. Duration is defined as the number of days from the first documentation of MRD- to the date of MRD status change (not MRD-).
- Expansion part: Incidence and severity of AEs [ Time Frame: From first dose until the end of the safety follow-up period (60 days after last dose) ]TEAEs
- Expansion part: Number of participants with clinically significant shifts from baseline in clinical laboratory parameters [ Time Frame: From first dose until the end of the safety follow-up period (60 days after last dose) ]Clinical laboratory parameters assessed: biochemistry, hematology including immunophenotyping).
- Expansion part: Changes in lymphoma symptoms as measured by the Functional Assessment of Cancer Therapy - Lymphoma (FACT-Lym) [ Time Frame: From first dose until up to 1 year after the last participant's first dose ]Monitor change from baseline in health-related quality of life over time and in relation to treatment.
