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

14 years to 75 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • Sign the informed consent and be willing and able to comply with the visit, treatment protocol, laboratory examination, and other requirements of the study as specified in the study procedure sheet;
  • Diagnosed as recurrent or refractory lymphoma, leukemia or myeloma;
  • Tumor cells express targets for CAR-T cell therapy (results: flow cytometry or Immunohistochemical test confirmation);

  • Subjects who received CAR-T therapy or other gene modified cell therapy before screening;
  • Conditions that the investigator believes may increase the risk to the subject or interfere with the outcome of the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety: Incidence and severity of adverse events
Time Frame: First 1 month post CAR-T cells infusion

Efficacy: Remission Rate
Time Frame: 3 months post CAR-T cells infusion
Complete remission (CR) Complete remission with incomplete recovery of blood cells (CRI), positive minimal residual tumor (MRD+) or negative tumor (MRD -) CR/CRI, disease recurrence or progression (PD) were evaluated, and the overall remission rate was ORR=CR+CRI; For drenching Complete remission (CR), partial remission (PR), disease stability (SD) Disease recurrence or progression (PD) was evaluated, and the overall remission rate was ORR=CR+PR; For multiple myeloma Complete remission (CR), partial remission (VGPR, PR), disease stability (SD), disease recurrence or progression (PD) were adopted, Overall remission rate ORR=CR+VGPR+PR;
3 months post CAR-T cells infusion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
