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

This is a multi-center, open label, phase Ib clinical study. The effectiveness of the multiple-dose regimen of recombinant human thrombopoietin injection in the treatment of thrombocytopenia in patients with chronic liver disease is mainly verified by evaluating the proportion of responders with platelet count in the first 8 days after treatment. Cohort 1 (n=18) : 50*10^9/L ≤ Baseline of PLT < 75*10^9/L. Cohort 2 (n=36) : 30*10^9/L ≤ Baseline of PLT < 50*10^9/L.

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.
