Adult B-ALL Treated by CART Cell Bridging Allogeneic Hematopoietic Stem Cell Transplantation

November 11, 2020 updated by: Hebei Senlang Biotechnology Inc., Ltd.

A Clinical Trial to Explore the Safety, Efficacy, and Remission Phase of CAR-T Cell in the Treatment of Adult Relapsed Refractory (R/R) Acute Lymphoblastic Leukemia Bridging Allogeneic Hematopoietic Stem Cell Transplantation

This is an open, single-arm, phase I/phase II clinical study to evaluate efficacy and safety of chimeric antigen receptor T cell immunotherapy (CAR-T) in the treatment of Relapsed Refractory (R/R) adult acute lymphoblastic leukemia bridging allogeneic hematopoietic stem cell transplantation.

Study Overview

Status

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

This trial openly recruited 50 patients into the group and were given CAR-T treatment. Patients participating in clinical trials will be tested and evaluated in terms of treatment safety, efficacy, and response duration. As assessed by clinicians, adult B-ALL patients who meet the enrollment criteria, after adequate communication, the patient or family members voluntarily join the clinical study, and are willing to bridge allogeneic hematopoiesis within 3 months after enrollment using CAR-T therapy。

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.

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.

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.
