Lymphoma drug combo trial for youth halted after just 5 patients
NCT ID NCT05255601
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase trial tested a combination of two immune-boosting drugs, relatlimab and nivolumab, in children and young adults with Hodgkin or non-Hodgkin lymphoma that had come back or not responded to treatment. The goal was to check safety, drug levels, and whether the tumors shrank. However, the study was stopped early after enrolling only 5 participants, so we don't have enough information to know if this approach works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- relatlimab and nivolumab (immune-boosting drugs)
- What this could lead to
- If it had worked, this combination might have offered a new treatment option for young people with lymphoma that didn't respond to standard therapy.
- What could go wrong
- The trial was terminated early with only 5 participants, so we have very little data. It's too early to know if the combination is safe or effective.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Participants with pathologically confirmed high-risk R/R cHL, after non-response to or failure of 1or more lines of standard therapy. * Participants with pathologically confirmed R/R NHL after non-response to or failure of 1or more lines of standard therapy, including, but not limited to, R/R primary mediastinal B-cell lymphoma, diffuse large B-cell lymphoma (DLBCL), mediastinal gray zone lymphoma (MGZL), anaplastic large cell lymphoma (ALCL), or peripheral T-cell lymphoma (PTCL). * Participants with pathologically confirmed R/R NHL after non-response to or failure of 2 or more lines of standard therapy, including Burkitt lymphoma (blast count \<25% malignant Burkitt cells and/or per the investigator's clinical assessment of risk status), lymphoblastic lymphoma (blast count \< 25% of marrow nucleated cells and/or per the investigator's clinical assessment of risk status), NK/T-cell lymphoma (nasal and non-nasal NK/T-cell lymphoma subtypes, but not aggressive NK/T-cell leukemia/lymphoma subtype). * The participant's current disease state must be R/R to standard therapy. * Participants must have measurable PET positive disease in both cHL and NHL cohorts. Exclusion Criteria: * Primary CNS lymphoma of the brain or spinal cord, and secondary CNS lymphoma (ie, from systemic non-Hodgkin lymphoma) involving the brain, spinal cord, or with leptomeningeal seeding. * Prior treatment with an anti-cytotoxic T-lymphocyte-associated protein 4 (anti-CTLA-4) antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways, with the exception of anti-PD(L)-1 targeted therapies. * Prior treatment with lymphocyte activation gene-3 (LAG-3)-targeted agents. * Participants with clinically significant systemic illnesses unrelated to the cancer as judged by the investigators, which would compromise the participant's ability to tolerate the study treatment. * Participants with autoimmune disease. * Prior allogeneic bone marrow transplantation. Other protocol-defined inclusion/exclusion criteria apply
