About this study

Official title: Phase I/II Study of Dual CD19-CD22 Chimeric Antigen Receptor (CAR) T Cells in Patients With Advanced CD19+ CD22+ Lymphoid Malignancies

This phase I/II trial studies the side effects and best dose of modified immune cells called CD19-CD22 chimeric antigen receptor (CAR) T cells in treating patients with CD19 positive(+), CD22+ B-acute lymphoblastic leukemia, chronic lymphocytic leukemia, or non-Hodgkin's lymphoma that has come back (recurrent) or does not respond to treatment (refractory). T-cells are collected from the patient and genetic materials called "chimeric antigen receptors (CAR)" are transferred to the collected T-cells. The CAR T-cells are then infused back to the patient's body. Giving CD19- CD22 CAR T cells after chemotherapy may help to control the disease.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the safety of infusion with chimeric antigen receptor T cells targeting CD19 and CD22.

II. To find the recommended phase II dose for recurrent/refractory CD19+CD22+ B cell malignancies.

SECONDARY OBJECTIVES:

  1. To describe the overall response rate and complete response rate of relapsed B cell malignancies treated with CAR-T cells targeting CD19 and CD22.

II. To assess other response variables including minimal residual disease (MRD) negative remission, overall survival (OS), and event free survival (EFS).

EXPLORATORY OBJECTIVES:

  1. To evaluate the immune reconstitution and persistence of CAR T cells for one year post infusion.

OUTLINE: This is a phase I, dose escalation study of autologous CD19/CD22 chimeric antigen receptor T-cells (CD19-CD22 CAR T cells) followed by a phase II study.

Patients receive standard of care cyclophosphamide intravenously (IV) over 30 minutes and fludarabine IV over 30 minutes on days -5, -4, and -3, and then receive CD19-CD22 CAR T cells IV on day 0. Patients with relapsed or persistent disease after a protocol assessment may receive a second infusion of CD19-CD22 CAR T cells.

After completion of study treatment, patients are followed up at 1, 2, 3, 6, and 12 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Optimal chimeric antigen receptor (CAR) T cell dose level

    Dose-finding will be done using the sequentially adaptive phase I-II EffTox method.

    Measured: Up to 30 days

  2. Incidence of adverse events (adverse events)

    Toxicity is defined as a grade 3, 4, or 5 cytokine release syndrome, neurotoxicity, or National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 5.0 with onset within 30 days of cell infusion. Adverse events that are considered disease-related (not suspected of relationship to CD19-CD22 -CAR T cells) will not be considered dose-limiting toxicities. Only those AEs that occur during the first 30 days after infusion, which are suspected to be related to conditioning lymphodepletion chemotherapy regimen and/or CD19 -CD22-CAR T cells (any component of the treatment regimen), and meet the following criteria, will be used in the definition of toxicity. Hematologic toxicities will not be considered in the definition of toxicity, as pancytopenia is a common toxicity with this regimen.

    Measured: Up to 30 days

  3. Efficacy in complete response (CR) or partial response

    Efficacy is defined as the patient being alive and in complete response (CR) or partial response (PR) at day 30 post cell infusion.

    Measured: Day 30 post cell infusion

Secondary outcomes (2)
  1. Progression-free survival

    Unadjusted distributions of the time-to-event outcomes will be estimated using the method of Kaplan and Meier and their relationship to prognostic covariates and T-cell dose level will be evaluated by Bayesian piecewise exponential survival regression.

    Measured: Up to 1 year post T-cell infusion

  2. Overall survival

    Unadjusted distributions of the time-to-event outcomes will be estimated using the method of Kaplan and Meier and their relationship to prognostic covariates and T-cell dose level will be evaluated by Bayesian piecewise exponential survival regression.

    Measured: Up to 1 year post T-cell infusion

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Autologous CD19/CD22 Chimeric Antigen Receptor T-cells, Cyclophosphamide and Fludarabine in people with CD19 Positive and CD22 Positive, run by M.D. Anderson Cancer Center 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 23 inclusion and 8 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: withdrawn, as of the sponsor's last update on 21 Aug 2023. 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 combined 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.

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Optimal chimeric antigen receptor (CAR) T cell dose level (time frame: Up to 30 days). The study lists 3 primary outcomes in all. 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 21 Aug 2023.
