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

The study is a single-center study.

  1. Screening period: All volunteers are required to sign a written informed consent form for the study; after the signing of informed consent form, the demographic data and medical history of the volunteers will be collected, and physical examinations and local laboratory tests will be performed to assess the eligibility of the volunteers. Volunteers who meet all the inclusion criteria and do not meet any exclusion criteria (except for the basic biological indicators of UCAR-T product preparation) will receive peripheral venous whole blood sampling, and the volunteers receiving apheresis based on the assessment results will be enrolled.
  2. Apheresis period: 5 volunteers who meet the inclusion criteria will undergo collection of peripheral blood mononuclear cells (PBMC) by means of apheresis.

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.
