About this study

Official title: A Phase I Study of Anti-CD22:TCRz:4-1BB T-cells in Patient With CD22-Positive Recurrent Lymphoma That is Resistant or Refractory to Prior Anti-CD22:TCRz:CD28 Immunotherapy

The goal of this clinical trial is to study the feasibility and efficacy of anti-CD22:TCRz:4-1BB chimeric antigen receptor (CAR)-modified T (CAR-T) cells in treating recurrent patients with refractory or resistant lymphoma to anti-CD19:TCRz:CD28 CAR-T cells. Recently, cancer immunotherapy, treatments aiming to arm patients with immunity specifically against cancer cells, has emerged as a promising therapeutic strategy. Among the many emerging immunotherapeutic approaches, clinical trials utilizing CARs against B cell malignancies have demonstrated remarkable potential. CARs combine the variable region of an antibody with T-cell signaling moieties to confer T-cell activation with the targeting specificity of an antibody. Thus, CARs are not MHC-restricted so they are not vulnerable to MHC down regulation by tumors. However, defined by the recession of evaluable lesions, the persistence and efficacy of CAR-T cells are still restricted by the "target" selection. Previous clinical studies largely utilized CD19 for the in vivo targeting of CAR-T cells, which preferentially become refractory or resistant due to the heterogeneity of lymphoma. This clinical investigation is to test a hypothesis whether anti-CD22 CAR-T cells work more effective in lymphoma patients refractory or resistent to anti-CD19:TCRz:CD28 CAR-T cells.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Retroviral vector-transduced autologous T cells to express CD22-specific CARs in people with Recurrent Adult Diffuse Large Cell Lymphoma and Recurrent Follicular Lymphoma, run by Xinqiao Hospital of Chongqing 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 15 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: status not confirmed, as of the sponsor's last update on 10 Mar 2017. 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?

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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety measured by occurrence of study related adverse effects defined by NCI CTCAE 4.0 (time frame: 4 Weeks). 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 10 Mar 2017.
