rhTPO in Critical Patients With Thrombocytopenia

May 19, 2015 updated by: Jianan Ren, Jinling Hospital, China

A Randomized, Open-label, Placebo-controlled, Multi-center Study to Evaluate Safety and Efficacy of Recombinant Human Thrombopoietin Among Severe Sepsis Patients With Thrombocytopenia

The primary objectives of this study are to assess the impact of rhTPO on mortality among severe sepsis patients with thrombocytopenia, as well as changes of platelet counts and platelet transfusion rates.

Study Overview

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

Thrombocytopenia is prevalent among critical patients who is admitted to intensive care unit. Researches have shown that thrombocytopenia is associated with mortality among those patients. Currently, no standard therapy exist for critical patients with Thrombocytopenia. In 2012 SSC guideline, platelet transfusion is induced for thrombocytopenia in critical patients for reducing the risk of bleeding. However, indication for platelet transfusion is relatively strict. No early intervention could be done according to this guideline. Previous studies have shown that recombinant human thrombopoietin can reduce severe sepsis with low platelet 28-day mortality in patients with hyperlipidemia, effectively improve peripheral platelet number, reducing the probability of platelet transfusion.The primary objectives of this study are to assess the impact of rhTPO on mortality among severe sepsis patients with thrombocytopenia, as well as changes of platelet counts and platelet transfusion rates.

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.

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.
