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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Influenza virus infections result in major health and economic burdens worldwide. The World Health Organization estimates that the average global burden of interpandemic influenza is approximately 1 billion cases of influenza, from 3 to 5 million cases of severe illness, and from 300 000 to 500 000 deaths annually. Arbidol (Umifenovir) is currently licensed for the treatment and prevention of influenza in Russian Federation. Arbidol (Umifenovir) has a direct antiviral effect. Arbidol (Umifenovir) belongs to fusion inhibitors; it interacts with the virus hemagglutinin and thus prevents fusion of the viral envelope with cell membranes. The aim of the study is to obtain additional data on safety and therapeutic efficacy of investigational product Arbidol (Umifenovir) in patients with a diagnosis of influenza and common cold. Furthermore, study of viral resistance in patients with seasonal influenza infection treated with Arbidol (Umifenovir) will be performed.

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

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers
