Donor-derived Anti-CD123-CART Cells for Recurred AML After Allo-HSCT

June 13, 2017 updated by: Chen Hu, Affiliated Hospital to Academy of Military Medical Sciences

Donor-derived Anti-CD123 Chimeric Antigen Receptors Modified T Cells for Recurred Acute Myeloid Leukaemia After Allogeneic Hematopoietic Stem Cell Transplantation

Patients with acute myeloid leukemia(AML) recurred after the allogeneic hematopoietic stem cell transplantation (allo-HSCT) have a dismal prognosis.The investigators developed donor-derived chimeric antigen receptor modified-T cell(CART) to target CD123 for the treatment of AML. The investigators start the Phase I study aimed to treat recurred post-transplantation AML patients using donor-derived CAR-T. The purpose of this study is to assess the safety and effectiveness of anti-CD123 CAR-T cells in patients.

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

Allo-HSCT is increasingly being used for AML, however, leukemia relapse remain a main problem for decades.Recently the investigators have witnessed great progresses in cancer therapy with chimeric antigen receptors modified T cells(CAR-T), especially for B-cell malignance. preclinical data about anti-CD123 CART have shown raised serious safety concerns of human anti-CD123 CAR-T for severe impairment of normal hematopoiesis in NSG mice.Patients with AML recurred after allo-HSCT have a dismal prognosis.The investigators developed donor-derived CART to target CD123 for the treatment of AML. The investigators start the Phase I study aimed to recurred post-transplantation AML patients using donor-derived CAR-T. The purpose of this study is to assess the safety and effectiveness of anti-CD123 CAR-T cells in patients.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
