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.

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
Evaluation of treatment response
Time Frame: Change from before and 2,4,6 and 8 weeks after initiating DEP combine with PD-1 antibody therapy
The primary observed endpoint is the objective remission rate (ORR): cases that include complete remission (CR) and partial remission (PR).CR was defined as normalization of all of the quantifiable symptoms and laboratory markers of HLH, including levels of sCD25, ferritin, and triglyceride; hemoglobin; neutrophil counts; platelet counts; and alanine aminotransferase (ALT). PR was defined as at least a 25% improvement in 2 or more quantifiable symptoms and laboratory markers as follows: sCD25 response was>1.5-fold decreased; ferritin and triglyceride decreased at least 25%; for patients with an initial neutrophil count of<0.5 ×109/L, a response was defined as an increase by at least 100% to>0.5× 109/L; for patients with a neutrophil count of 0.5 to 2.0 × 109/L, an increase by at least 100% to >2.0 × 109/L was considered a response; and for patients with ALT >400 U/L, response was defined as an ALT decrease of at least 50%.
Change from before and 2,4,6 and 8 weeks after initiating DEP combine with PD-1 antibody therapy

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.
Outcome Measure
Measure Description
Time Frame
Survival
Time Frame: 3 months after the intervention
Outcome of patients with EBV-HLH
3 months after the intervention
Adverse events that are related to treatment
Time Frame: 2,4,6 and 8 weeks after initiating DEP combine with PD-1 antibody therapy
Incidence of events that are related to treatment including myelosuppression, infection, bleeding and so on.
2,4,6 and 8 weeks after initiating DEP combine with PD-1 antibody therapy
EBV-DNA
Time Frame: Change from before and 2,4,6 and 8 weeks after initiating DEP combine with PD-1 antibody therapy
EBV-DNA copies/ml in peripheral blood
Change from before and 2,4,6 and 8 weeks after initiating DEP combine with PD-1 antibody therapy

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
