CD19-directed CAR T Cells Therapy in Relapsed/Refractory B Cell Malignancy

November 29, 2018 updated by: Aibin Liang，MD，Ph.D., Shanghai Tongji Hospital, Tongji University School of Medicine

CD19-directed Chimeric Antigen Receptor T Cells Therapy in Relapsed/Refractory B Cell Malignancy

Relapsed/refractory leukemia and lymphoma lack effective treatment. The cancer immunotherapy with chimeric antigen receptor (CAR) T cells provides a potent new approach for them. In this clinical trial, the investigators aim to assess the safety and efficacy of administering T cell expressing an anti-CD19 CARs to patients with chemotherapy resistant or refractory CD19 positive B cell malignancy including leukemia and lymphoma.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Tongji Hospital of Tongji University has developed an investigational approach for treating patients with CD19 positive B cell malignancy that involves taking white blood cells from the patient, growing them in the laboratory in large numbers, genetically modifying these specific cells with lentivirus to attack CD19 positive cells, and then giving the cells back to the patients.The main purpose of the study is to assess the safety and efficacy of the treatment with anti-CD19 CAR-T cells in the patients with chemotherapy resistant or refractory CD19 positive B cell malignancy including leukemia and lymphoma.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

6 years to 85 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
