About this study

Official title: A Phase I Clinical Trial with CAR-37 T Cells for the Treatment of Patients with Relapsed or Refractory CD37+ Hematologic Malignancies

This research study is studying Chimeric Antigen Receptor (CAR)-37 T Cells (CAR-37 T Cells) for treating people with relapsed or refractory CD37+ hematologic malignancies and to understand the side effects when treated with CAR-37 T Cells.

  • Chimeric Antigen Receptor (CAR)-37 T Cells (CAR-37 T Cells) is an investigational treatment
Read the detailed description

This is a two-part, non randomized, open label, single site Phase 1 study. Participants who fulfill eligibility criteria will be entered into the trial Chimeric Antigen Receptor (CAR)-37 T Cells (CAR-37 T Cells).

This study consists of 2 parts:

  • Part A (Dose Escalation): The investigators are looking the highest dose of the study intervention that can be administered safely without severe or unmanageable side effects in participants that have relapsed or refractory CD37+ hematologic malignancies, not everyone who participates in this research study will receive the same dose of the study intervention. The dose given will depend on the number of participants who have been enrolled prior and how well the dose was tolerated
  • Part B (Expansion Cohort): Part B: Expansion Cohort: Participants will be treated at the respective dose (at or below the Maximum Tolerated Dose), as determined during Part A (Dose Escalation).
  • A total of 18 participants will be enrolled to this trial

This research study is a Phase I clinical trial, which tests the safety of an investigational intervention and also tries to define the appropriate dose of the investigational intervention to use for further studies.

Investigational" means that the intervention is being studied The U.S. Food and Drug Administration (FDA) has not approved CAR-37 T Cells as a treatment for any disease.

This is the first time that CAR-37 T Cells will be given to humans

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CAR-37 T cells in people with Hematologic Malignancy and Leukemia, run by Marcela V. Maus, M.D.,Ph.D. at 1 site 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 53 inclusion and 13 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: finished, as of the sponsor's last update on 12 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose Limiting Toxicity (time frame: 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04136275, which also lists 2 linked publications.

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 12 Dec 2024; AzTrials last refreshed its copy on 30 Oct 2026.
