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 a phase 1b clinical trial to investigate the safety and preliminary effects of a single dose of a test drug or placebo to the subjects who has diagnosed as COVID-19 infection.

Study design: prospective, randomized, placebo-controlled, single-blind, single-center

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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

19 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Key Inclusion Criteria:

  1. Subjects who have been confirmed to be COVID-19 corresponding to mild cases of severity categorization classified by FDA through polymerase chain reaction (PCR) test or virus gene test (sequencing) and who can be available to be administered within seven days from the date of manifestation.
  2. Subjects who are or will be inpatient.

Key Exclusion Criteria:

  1. Patients with symptoms of moderate or higher in the severity classification presented by FDA have evidence of lower respiratory tract infection in their imaging findings or need supplemental oxygen therapy or mechanical respiration (ie, non-invasive ventilation, invasive mechanical ventilation, extracorporeal membrane oxygenation, etc)
  2. Subjects with infectious diseases such as bacteremia or severe pneumonia requiring active treatment within four weeks prior to the IP administration

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.
