Lymphoma drug combo trial halted early – what we know
NCT ID NCT03769181
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This early-stage trial tested two drugs, isatuximab and cemiplimab, together in 58 people with relapsed or refractory lymphoma. The goal was to see if the combination was safe and could shrink tumors. The study was terminated early, so while some safety and response data were collected, the full potential of this approach remains unclear.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- isatuximab and cemiplimab
- What this could lead to
- If successful, this combination could offer a new treatment option for people with certain types of lymphoma that have not responded to other therapies.
- What could go wrong
- The trial was terminated early, so results are limited. It is still early-stage research, and the combination may not prove effective or safe for broader use.

Inclusion criteria: * Participants greater than or equal to (\>=) 12 years of age inclusive, at the time of signing the informed consent. * Disease location amenable to tumor biopsy at Baseline. * Measurable disease. * For Cohort A1 (cHL anti-programmed cell death protein 1/ligand 1 \[PD-1/PD-L1\] inhibitor naïve): Histologically confirmed advanced cHL that had relapsed or progressed after at least 3 lines of systemic therapy that included autologous hematopoietic stem cell transplant (auto-HSCT) or auto-HSCT and brentuximab vedotin (BV). * For Cohort A2 (cHL anti-PD-1/PD-L1 inhibitor progressor): Histologically confirmed advanced cHL which had relapsed or progressed after one previous anti-PD-1/PD-L1 containing regimen as the most recent prior therapy but no more than 4 lines of previous chemotherapy including the anti-PD-1/PD-L1 containing regimen and documentation of benefit during or after the anti-PD-1/PD-L1 containing regimen within 4 months prior to initiation of investigational medicinal product. * For Cohort B (diffuse large B-cell lymphoma \[DLBCL\]): Histologically confirmed advanced DLBCL that had relapsed or progressed after 2 lines of systemic therapy including auto-HSCT or 2 lines of systemic therapy for participants who were not eligible for auto-HSCT. * For Cohort C (peripheral T-cell lymphoma \[PTCL\]): Histologically confirmed advanced PTCL that had relapsed or progressed after either first-line chemotherapy and auto-HSCT as consolidation of first remission or first-line chemotherapy if participants were ineligible for auto-HSCT. * Body weight of greater than (\>) 45 kilograms for participants with age less than (\<)18 years. Exclusion criteria: * Prior exposure to agent that blocks CD38. * For participants with cHL (PD-1/PD-L1 naïve), DLBCL or PTCL prior exposure to any agent (approved or investigational) that blocks the PD-1/PD-L1, PD-L2, CD137, cytotic T-lymphocyte-associated protein 4 or LAG-3. * Evidence of other immune related disease/conditions. * Had received a live-virus vaccination within 28 days of planned treatment start; seasonal flu vaccines that do not contain live virus are permitted. * Eastern Cooperative Oncology Group (ECOG) performance status (PS) \>=2. * Poor bone marrow reserve. * Poor organ function. The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
