Study of the Use of the Drug Ingaron in Patients With COVID-19

Study Overview
=================
Brief Summary
-----------------
Interferon gamma is a powerful endogenous regulatory cytokine that activates the antiviral immune response, while it also has its own antiviral activity. The objective of this study was to evaluate the effectiveness of the proposed treatment regimen with Ingaron (INN: recombinant interferon gamma human, lyophilisate for preparing a solution for intramuscular and subcutaneous administration of 500,000 IU) in patients with viral pneumonia.

Detailed Description
-----------------
The study drug was prescribed for therapeutic purposes according to the following scheme: 500,000 IU s / c 1 time per day daily for 5 days. A total of 4 visits were scheduled. Visits 0 and 1 could be combined provided that the chronological sequence of screening and randomization procedures was followed. The main stages of the study: screening - lasting no more than 1 day; treatment - within 10-14 days, including the use of the investigational medicinal product for 5 days (from the first day of the basic therapy, daily). The total duration of observation is up to 14 days. Patients who completed participation in the study or dropped out of the study ahead of schedule were followed up by the attending physician in accordance with the rules for managing such patients for a medical institution.
