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 study is designed as a randomized, double-blind, placebo-controlled clinical trial, and is planned to be conducted at 3 clinical centers in China from January 1, 2023, to January 31, 2024. During the study period, we intend to enroll a total of 238 eligible patients. These patients will be randomly assigned in a 1:1 ratio to receive either sivelestat sodium or placebo via continuous intravenous infusion (0.2mg/kg/h) over a 24-hour period for 7 days (or to the day of death or ICU discharge if it occurs before day 7). Both the patients and investigators are blinded to the treatment assignment. Subsequent follow-ups will be performed in person at 7,14 and 28 days after randomization. The primary endpoint will be at 7 days post randomization and secondary endpoints will be at 14 and 28 days post randomization. Also, endpoint assessors are masked to the treatment allocation. Lastly, these endpoint variables will be compared between the treatment groups to investigate the efficacy and safety of sivelestat for COVID-19-associated ARDS

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.
