Immunotherapy injection tested against Hard-to-Treat childhood lymphoma
NCT ID NCT05206357
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Standard treatment cures most children with aggressive mature B-cell lymphomas, but those whose cancer returns or resists therapy have few options. This phase 1b trial tests epcoritamab, an experimental immunotherapy given as an injection under the skin, in children and young adults up to age 25 with relapsed or refractory Burkitt lymphoma, diffuse large B-cell lymphoma, or similar cancers. Researchers will track side effects, drug levels in the body, and whether the cancer shrinks. Participants receive the drug in 28-day cycles and are followed for at least three years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- epcoritamab, an experimental immunotherapy given as an injection under the skin
- What this could lead to
- If it works, epcoritamab could offer a new treatment option for children and young adults whose aggressive B-cell lymphoma has come back or stopped responding to standard therapy.
- What could go wrong
- This is a small, early-stage trial focused first on safety, so researchers do not yet know whether the drug helps. Children may face more clinic visits and side effects than with standard care.

Inclusion Criteria: * Participants \>= 1 and \< 18 years old at time of primary diagnosis with Burkitt's or Burkitt-like lymphoma/leukemia, diffuse large B-cell lymphoma (DLBCL), or other aggressive mature (CD20+) B-cell lymphomas. Participants up to 25 years of age with Burkitt's or Burkitt-like lymphoma/leukemia are also eligible. * Disease pathologically confirmed (tumor tissue) by local testing. * Relapsed or primary refractory disease meeting any of the following criteria: * Progressive disease at any time during second-line chemoimmunotherapy (CIT). * Best response of stable disease (SD) after a minimum of 2 cycles of second-line CIT. * Best response of partial response (PR) after a minimum of 3 cycles of second-line CIT. * Complete Response (CR) after a minimum of 3 cycles of second-line CIT therapy but unfit or ineligible for consolidation with cell therapy. * Not in CR and unable to initiate or tolerate (i.e., must discontinue) second-line CIT. * Have received cell therapy (allogeneic or autologous transplant or chimeric antigen receptor T-cell (CAR-T) therapy) as consolidation but have not obtained or maintained a CR. * Recovery from toxic effects of prior chemoimmunotherapy. * Performance status by Lansky (\< 16 years old at evaluation) or Karnofsky (\>= 16 years old at evaluation) score \>= 50 or Eastern Cooperative Oncology Group (ECOG) score \<= 2 . * Adequate bone marrow, hepatic, and renal function. Exclusion Criteria: * Known central nervous system (CNS) involvement by lymphoma at screening as confirmed by screening magnetic resonance imaging (MRI)/computed tomography (CT)/positron emission tomography (PET) brain scans (participants with evidence of CNS disease only in the cerebrospinal fluid (CSF) will be eligible). * Other malignancy requiring therapy. * Currently receiving anti-cancer therapy, including chemotherapy (excluding intrathecal therapy), radiotherapy, small molecules, monoclonal antibodies, cell therapy, or other investigational agents.
