About this study
Official title: Phase Ib Study to Assess the Efficacy and Safety of Epcoritamab in Relapsed or Refractory Post-Transplant Lymphoproliferative Disorder
This phase Ib trial tests the safety and effectiveness of epcoritamab in treating patients with post-transplant lymphoproliferative disorder (PTLD) that has come back after a period of improvement (relapsed) or has not responded to previous treatment (refractory). Epcoritamab, a bispecific antibody, binds to a protein called CD3, which is found on T cells (a type of white blood cell). It also binds to a protein called CD20, which is found on B cells (another type of white blood cell) and some lymphoma cells. This may help the immune system kill cancer cells. Giving epcoritamab may be safe and effective in treating patients with relapsed or refractory B-cell PTLD.
Read the detailed description
PRIMARY OBJECTIVE:
- To assess the safety of treatment with epcoritamab in subjects with PTLD.
SECONDARY OBJECTIVES:
- To estimate the Objective Response Rate (ORR), defined as the clinical response (complete response [CR] + partial response [PR]) after 3 cycles of epcoritamab.
II. To estimate the clinical benefit rate (CBR) in subjects with PTLD treated with epcoritamab.
III. To estimate the best objective response rate (BOR) in subjects with PTLD treated with epcoritamab.
IV. To estimate the progression free survival (PFS) in subjects with PTLD treated with epcoritamab.
- To estimate the duration of complete response (DoCR) in subjects with PTLD treated with epcoritamab.
VI. To estimate the overall survival (OS) in subjects with PTLD treated with epcoritamab.
EXPLORATORY OBJECTIVES:
- To characterize the peripheral immunophenotype changes through the course of treatment with epcoritamab in subjects with PTLD.
II. To describe the relationship of tumor microenvironment characteristics with clinical response to epcoritamab in subjects with PTLD.
III. To characterize Epstein-Barr virus (EBV) methylation alterations in EBV positive PTLDs treated with epcoritamab IV. To describe the relationship between metabolic tumor volume and response to epcoritamab in subjects with PTLD.
OUTLINE: This is a dose-escalation study of epcoritamab followed by a dose-expansion study.
Patients receive epcoritamab subcutaneously (SC) on days 1, 8, 15, and 22 of cycles 1 and 2, days 1 and 15 of cycles 4-9, and day 1 of each subsequent cycle. Cycles repeat every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients with CR may continue to receive epcoritamab if disease progression occurs within 6 months. Patients with PR or stable disease (SD) continue to receive epcoritamab in the absence of disease progression or unacceptable toxicity. Patients also undergo positron emission tomography (PET)/computed tomography (CT) and blood sample collection throughout the study and may undergo biopsy during screening.
After completion of study treatment, patients are followed up at 28 days and then every 3 months for up to 3 years.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Biopsy, Biospecimen Collection and Computed Tomography in people with Diffuse Large B-Cell Lymphoma Post-Transplant Lymphoproliferative Disorder and EBV-Related Post-Transplant Lymphoproliferative Disorder, run by Timothy Voorhees at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 26 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 24 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact The Ohio State University Comprehensive Cancer Center (800-293-5066, OSUCCCClinicaltrials@osumc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of adverse events (time frame: Up to 30 days after the last dose of the study drug). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Sep 2026; AzTrials last refreshed its copy on 26 Oct 2026.
