About this study

Official title: CD19 Chimeric Antigen Receptor (CAR) and PD-1 Knockout Engineered T Cells for CD19 Positive Malignant B-cell Derived Leukemia and Lymphoma

The purpose of this study is to evaluate the safety, efficacy and blood kinetics of autologous T cells genetically modified to express CD19 Chimeric Antigen Receptor and PD-1 knockout engineered T cells in patients with relapsed or refractory B-Cell Non-Hodgkin Lymphoma and Leukaemia.

Read the detailed description

This is a multi-centre, non-randomised, open label Phase I clinical trial of an Advanced Therapy Investigational Medicinal Product named CD19 Chimeric Antigen Receptor (CAR) and PD-1 knock out engineered T-cells (CD19 CAR and PD-1 knock out engineered T-cells) in children and adults (age <70 years) with high risk, relapsed CD19+ haematological malignancies (Acute Lymphoblastic Leukemia and Burkitt's lymphoma). Following informed consent and registration to the trial, patients will undergo an unstimulated leukapheresis for the generation of the CD19 CAR T-cells. Patients will receive the CD19 CAR and PD-1 knock out engineered T-cells following lymphodepleting chemotherapy. The study will evaluate the safety, efficacy and duration of response of the CD19 CAR and PD-1 knock out engineered T-cells in children with high risk relapsed CD19+ malignancies.

Being tested
CD19 CAR and PD-1 knock out engineered T-cells, CD19 CAR T-cells
Medical subject headings
Precursor Cell Lymphoblastic Leukemia-Lymphoma, Burkitt Lymphoma

What participants receive

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

  • CD19 CAR and PD-1 knock out engineered T-cellsBiological

    A single dose of 1 x 10^6/kg CD19 CAR transduced and PD-1 knock out engineered T-cells will be given as an intravenous injection through a Hickman line or PICC line(peripherally inserted central catheter) on day 0.

  • CD19 CAR T-cellsBiological

    A single dose of 1 x 10^6/kg CD19 CAR transduced T-cells will be given as an intravenous injection through a Hickman line or PICC line(peripherally inserted central catheter) on day 0.

What is being measured

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

  1. Molecular remission

    Efficacy will be assessed by determining Minimal Residual Disease in the bone marrow aspirate using immunoglobulin heavy chain (IgH) quantitative polymerase chain reaction (qPCR) and/or Next Generation Sequencing in all patients. The proportion of patients achieving molecular remission at 1 month post CD19 CAR and PD-1 Knockout Engineered T-cell infusion will be determined.

    Measured: 1 month

Secondary outcomes (5)
  1. Long term molecular remission

    Number of patients in molecular remission without further therapy at 2 years

    Measured: 2 years

  2. Frequency of circulating CD19 CAR and PD-1 Knockout Engineered T-cells

    Persistence and frequency of circulating CD19 CAR and PD-1 Knockout Engineered T-cells in the peripheral blood by flow cytometry and qPCR analyses.

    Measured: 2 years

  3. Incidence of hypogammaglobulinaemia

    Incidence and duration of hypogammaglobulinaemia.

    Measured: 2 years

  4. Relapse rate

    Relapse rate monitored during interventional phase and long term follow up for a total of 10 years post cell infusion. Number of patients who relapsed can be summarized as a percentage (for all patients registered to the trial, and also only for those who received the cell infusion).

    Measured: 10 years

  5. Overall Survival

    Overall survival is monitored during interventional phase and long term follow up for 10 years post-CD19 CAR and PD-1 Knockout Engineered T-cell infusion. Number of patients alive can be summarized as a percentage (for all patients registered to the trial, and also only for those who received the cell infusion).

    Measured: 10 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CD19 CAR and PD-1 knock out engineered T-cells and CD19 CAR T-cells in people with Acute Lymphoblastic Leukemia and Burkitt Lymphoma, run by Third Military Medical University.

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 17 inclusion and 12 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 2 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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

Contact Xiaoyun Shang, Dr. (+8618580607020, shangxiaoyun@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Molecular remission (time frame: 1 month). 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 2 Oct 2017.
