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 escalation part of the trial is to determine the maximum tolerated dose and the recommended phase 2 dose (RP2D) as well as to establish the safety profile of epcoritamab GEN3013 (DuoBody®-CD3xCD20) in patients with relapsed, progressive or refractory B-Cell Lymphoma.
In the expansion part additional patients will be treated with epcoritamab with the RP2D and the purpose is to further explore and determine the safety and efficacy of epcoritamab.

Experimental: Epcoritamab (GEN3013, DuoBody®-CD3xCD20)

- Escalation: Adverse Events (safety) to determine the Recommended Phase 2 Dose RP2D [ Time Frame: Adverse Events are assessed during the first cycle (28 days) in each cohort. ]-Number of Adverse Events, treatment emergent AEs as assessed by CTCAE V5.0.
- Escalation: Tolerability to determine the RP2D. [ Time Frame: DLTs are assessed during the first cycle (28 days) in each cohort. ]-Number of Dose limiting toxicities DLTs.
- Expansion: Safety, Adverse Event AE Evaluation. [ Time Frame: Until 1 year after last patient enters the trial, through study completion. ]-Total number of AEs and number of treatment emergent AEs as assessed by CTCAE V5.0.
- Expansion: Clinical Efficacy Evaluation. [ Time Frame: Until 1 year after last patient enters the trial, through study completion. ]-Antitumor activity as measured by the objective response rate according to Lugano classification
- Escalation and Expansion: Pharmacokinetic parameters Cmax [ Time Frame: Until 1 year after last patient enters the trial, through study completion. ]-PK, peak plasma concentration through concentration and half life.
- Escalation and Expansion: Pharmacokinetic parameters AUC [ Time Frame: During the first 4 doses in each patient ]-Maximum concentration AUC 0-Clast, AUC 0-x and half life.
- Escalation and Expansion: Immunogenicity-Anti Drug Antibody. [ Time Frame: Until 1 year after last patient enters the trial, through study completion. ]-ADA titers measured as positive or negative host immune response and compared to PK, safety and tumor response.
- Expansion: Evaluate Patient Reported Outcomes EQ-5D-3L. [ Time Frame: Until 1 year after last patient enters the trial, through study completion. ]-EQ-5D-3L; a six item questionnaire measuring changes from baseline; item 1 addressing a summary of the 5 next being; mobility, self care, usual activity, pain/discomfort, anxiety depression. Measured on a scale from 0 to 100, 100 being best.
- Expansion: Evaluate Patient Reported Outcomes FACT-Lym. [ Time Frame: Until 1 year after last patient enters the trial, through study completion. ]-FACT-Lym is a 2 module quality of life questionnaire measuring changes from baseline. FACT-G for quality of life and Lym a lymphoma specific questionnaire both using by a 5 point scale 0-4, 4 being best.
