Phase I Clinical Trial of Autologous CD7-CAR T Cell Therapy for High-risk Acute T-cell Leukemia/lymphoma

November 12, 2024 updated by: Beijing Boren Hospital

Phase I Clinical Trial of Autologous CD7-CAR T Cells in the Treatment of High-risk Acute T-cell Leukemia / Lymphoma

This is a phase 1 clinical trial of autologous CD7-CAR T cells in the treatment of high-risk acute T-cell leukemia / lymphoma. Twenty subjects will be enrolled. Subjects will be pretreated with chemotherapy prior to infusion of CAR T cells: about 3 days before cells transfusion, the patients who planned to reinfuse CAR T cells were treated with fluorodarabine 30 mg/m2( body surface area) and cyclophosphamide 250 mg/m2( body surface area) for 3 days. Then this study will be using a 3+3 dose escalation approach from dose 1 (DL-1): 5×105 (±20%) to dose 2 (dl-2): 1×106 (±20%). Below the lowest dose was reinfused at the PI's discretion.

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.

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
