About this study
Official title: A Phase 2 Trial of Emapalumab for the Prevention of CAR-T Cell Associated Toxicities
This research study involves assessing the impact of emapalumab as preventative management of CAR-T related cytokine release syndrome in participants with Non-Hodgkin's lymphoma (NHL).
The research study involves the following study interventions:
- Fludarabine and cyclophosphamide (Lymphodepleting Chemotherapy)
- Axicabtagene Ciloleucel or Lisocabtagene Maraleucel
- Emapalumab
Read the detailed description
This is a phase 2 multi-center, open label study that is evaluating the safety and efficacy of emapalumab in preventing toxicities associated with FDA Approved, CD19-directed CAR-T in subjects with second- or third-line large B-cell non-Hodgkin's lymphoma.
A phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied.
The U.S. Food and Drug Administration (FDA) has not approved emapalumab for the participants specific disease, but it has been approved for other uses.
The U.S. FDA has approved axicabtagene ciloleucel and lisocabtagene maraleucel for the participants specific disease.
This research study procedures include screening for eligibility, study treatment including collection of T cells (leukapheresis), lymphodepleting chemotherapy, treatment with emapalumab and axicabtagene ciloleucel or lisocabtagene maraleucel, and follow-up evaluations.
Once study treatment is completed, the participants will be followed for up to 24 months.
It is expected that about 28 people will take part in this research study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of grade 2+ CRS per ASTCT
Assessed using American Society for Transplantation and Cellular Therapy (ASTCT). All participants will be monitored and assessed for grade 2+ cytokine release syndrome (CRS) for 24 months after post treatment.
Measured: Day -1 to 24 months post treatment
Secondary outcomes (2)
Rate and severity of ICANS as per ASTCT
Assessed using American Society for Transplantation and Cellular Therapy (ASTCT). The rate and severity of immune cell associated neurotoxicity syndrome (ICANS) within the first 30 days of infusion.
Measured: 30 days
Objective response rate (ORR)
The incidence of either a complete response or a partial response by Lugano. All subjects that do not meet the criteria for an objective response by the analysis data cutoff date will be considered non-responders.
Measured: Day -1 to 24 months post treatment

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Emapalumab, Cyclophosphamide and Fludarabine Phosphate in people with Large B-cell Lymphoma and Relapsed Non-Hodgkin Lymphoma, run by Marcela V. Maus, M.D.,Ph.D. 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 15 inclusion and 19 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 6 Oct 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 Matthew Frigault, MD ((617) 643-6175, MFRIGAULT@partners.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of grade 2+ CRS per ASTCT (time frame: Day -1 to 24 months post treatment). 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 6 Oct 2026.
