Anti-CD19 CAR-T Therapy Bridging to HSCT for CD19+ B-Cell Malignancies

May 8, 2019 updated by: Wuhan Sian Medical Technology Co., Ltd

A Phase 1/2 Study Evaluating the Safety and Efficacy of Anti-CD19 Chimeric Antigen Receptor-Modified T Cell (CAR-T) Therapy Bridging to Hematological Stem Cell Transplantation (HSCT) for Relapsed/Refractory CD19+ B-Cell Malignancies

This is the second stage of the previous anti-CD19 CAR-T therapy (NCT02965092). The study aims to evaluate the safety and efficacy of consolidative allo-HSCT following CAR-T therapy in patients with relapsed or refractory B cell Malignancies.

Study Overview

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

Anti-CD19 CAR-T therapy has been confirmed effective for relapsed/refractory B-cell malignancies. However, its ability to keep patients in maintained remission is limited. In order to keep patients in long-term remissions, patients who had achieved MRD-negative complete remissions through CAR-T therapy (NCT02965092) will, on their own accord, receive allo-HSCT if there are no previous HSCT, contraindications, and other restrictions.

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

No older than 70 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

What is the study measuring?
