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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Researchers evaluate patients with newly diagnosed or refractory/relapsed HLH disease.
  2. Definite diagnosis of HLH: molecular diagnosis consistent with pHLH, or at least 5 of the 8 criteria in the HLH-2004 diagnostic criteria.
  3. Patients who are currently unsuitable or unable to undergo allo-HSCT.
  4. Researchers estimate that the expected survival period exceeds one month.
  5. Patients must be at least 14 years of age and no older than 70 years of age, with no gender restrictions.
  6. Before the study began, TB was ≤10 times the upper limit of normal; Cr was ≤1.5 times the normal value.
  7. Serum HIV antigen or antibody negative。
  8. HCV antibody negative, or HCV antibody positive but HCV RNA negative.
  9. .HBsAg and HBcAb are both negative. If either of the above is positive, peripheral blood hepatitis B virus DNA titer testing is required, with a titer of less than 1×10³ copies/ml.
  10. Echocardiography showed LVEF ≥ 50%.
  11. Women of childbearing age must be confirmed as not pregnant by a pregnancy test and must be willing to use effective contraception during the study period and for at least 12 months after the last dose; all male participants must use contraception during the study period and for at least 3 months after the last dose.

Exclusion Criteria:

  1. Heart function above grade II(including II) (NYHA).

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.

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: Weeks 2, 4, 6, and 8 after the start of treatment

A complete response was defined as normalization of all of the quantifiable symptoms and laboratory markers of HLH, including levels of sCD25, ferritin, triglyceride, blood cell count, hemophagocytosis, and level of consciousness (if CNS HLH is present).

A partial response 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%; without blood transfusion: Neutrophils <500/ml must increase by 100% and be >500/ml; neutrophils 500-2000/ml must increase by 100% and return to normal.; and for patients with ALT >400 U/L, response was defined as an ALT decrease of at least 50%.

No response is defined as not meeting the criteria for partial response.
Weeks 2, 4, 6, and 8 after the start of treatment

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
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0
Time Frame: 30 days after the last dose is administered.

An adverse event is defined as an adverse medical condition (including worsening of a pre-existing condition) that occurs in a subject or clinical trial subject after receiving medication, regardless of whether it is causally related to the investigational drug.

Serious adverse events are defined as AEs that meet one or more of the following criteria during any study period: death; immediate threat to life; and hospitalization or prolongation of hospitalization.
30 days after the last dose is administered.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Primary Completion (Estimated)

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.
