Safety & Efficacy Study of Epcoritamab in Subjects With R/R Chronic Lymphocytic Leukemia and Richter's Syndrome

Official Title

A Phase 1b/2, Open-Label, Safety and Efficacy Study of Epcoritamab (GEN3013; DuoBody®-CD3 X CD20) in Relapsed/Refractory Chronic Lymphocytic Leukemia and Richter's Syndrome

Brief Summary

      The trial is an open-label, multi-center safety and efficacy trial of epcoritamab in
      relapsed/refractory chronic lymphocytic leukemia (R/R CLL) and Ritcher's Syndrome (RS). The
      trial consists of two parts, a dose escalation phase (phase Ib) and an expansion phase (phase
      II).
    

Detailed Description

      The purpose of the escalation phase of the trial is to determine the recommended phase 2 dose
      (RP2D) and the maximum tolerated dose (MTD; if reached) as well as establish the safety
      profile of epcoritamab in patients with R/R CLL.

      In the expansion phase, additional patients will be treated with epcoritamab at the RP2D and
      the purpose is to assess and evaluate the preliminary efficacy, safety and tolerability
      profiles of epcoritamab at the RP2D for R/R CLL and RS.
    

Study Phase

Phase 1/Phase 2

Study Type

Interventional


Primary Outcome

Secondary Outcome

 Dose expansion phase: Incidence of AEs

Condition

Relapsed/Refractory Chronic Lymphocytic Leukemia

Epcoritamab

Study Arms / Comparison Groups

 Epcoritamab in R/R CLL
Description:  R/R CLL: in both dose escalation and dose expansion phases. Patients in the dose expansion phase will be treated at the RP2D defined in the dose escalation phase.
