About this study

A Study of Metabolically Armed CD19 CAR-T Cells Therapy for Patients With Relapsed and/or Refractory B-cell Acute Lymphoblastic Leukemia

Read the detailed description

This is a single arm , open-label study. This study is indicated for relapsed and/or refractory CD19+ B-cell Acute Lymphoblastic Leukemia . The selections of dose levels and the number of subjects are based on clinical trials of similar foreign products.

  1. Main research objectives: To evaluate the safety and efficacy of metabolically armed CD19 CAR-T Cells in the treatment of r/r B-ALL.
  2. Secondary research objectives:
  3. To evaluate the pharmacokinetic (PK) and pharmacodynamics(PD) characteristics of metabolically armed CD19 CAR-T Cells after infusion.
  4. To evaluate tumor remission after infusion of metabolically armed CD19 CAR-T Cells.
Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Metabolically Armed CD19 CAR-T cellsDrug

    Also called Meta10-19

    Each subject receive metabolically armed CD19 CAR-T cells by intravenous infusion.

Study groups in NCT05747157
Study groupRoleWhat they receive
Administration of Metabolically Armed CD19 CAR-T cellsExperimentalPatients undergo leukapheresis. Patients will receive a lymphodepletion chemotherapy with cyclophosphamide and fludarabine before CAR-T cells infusion. A dose of metabolically armed CD19 CAR-T cells will be infused on day 0.
Receives: Drug: Metabolically Armed CD19 CAR-T cells

What is being measured

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

  1. MTD

    Determine the Maximal Tolerable Dose(MTD)

    Measured: MTD will be determined based on DLTs observed during the first 28 days of study treatment

  2. Objective response rate (ORR)

    Measure Tumor response rate (including CR and PR)

    Measured: Within 3 months following infusion of Meta10- 19

Secondary outcomes (2)

  1. Pharmacokinetics

    The number of CAR-T cells in peripheral blood was measured to evaluate the persistence of CAR-T cells

    Measured: Up to 12 months after CAR-T treatment

  2. Pharmacodynamics

    Peak level of cytokines in peripheral blood

    Measured: Up to 28 days after infusion

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Metabolically Armed CD19 CAR-T cells in people with B-cell Acute Lymphoblastic Leukemia, run by Anhui Provincial Hospital at 1 site in China.

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 24 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 21 Nov 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 China. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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

Contact Xingbing Wang, PhD (86-13856007984, wangxingbing@ustc.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

MTD (time frame: MTD will be determined based on DLTs observed during the first 28 days of study treatment). 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 NCT05747157, which also lists 1 linked publication.

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 Nov 2023.
