Clinical Trial for the Safety and Efficacy of Anti-CD7 CAR-T Cell Therapy for Patients With Relapsed or Refractory CD7 Positive Hematological Malignancy

November 29, 2023 updated by: He Huang, Zhejiang University

Clinical Trial for the Safety and Efficacy of Anti-CD7 Chimeric Antigen Receptor Cell Therapy for Patients With Relapsed or Refractory CD7 Positive Hematological Malignancy

This is a prospective, open-label, single-center clinical trial. This study will evaluate the safety and efficacy of anti-CD7 CAR-T cells in the treatment of relapsed or refractory CD7 positive T-ALL/LBL, T-NHL and AML. The primary endpoints are dose limiting toxicity (DLT) and the incidence of treatment emergent adverse event (TEAE).

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

8 months to 76 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No
