Study summary

The purpose of the study is to evaluate an effectiveness of the drug Dalargin in combination with Leitragin for the prevention and treatment of severe pulmonary complications symptoms associated with severe and critical coronavirus infection cases (SARS COVID19, expanded as Severe acute respiratory syndrome Cоrona Virus Disease 2019 ).

Test drugs that will be administered to patients are:

  • Leitragin, solution for inhalation administration,
  • Dalargin, solution for intravenous and intramuscular administration.

  2. To study the effectiveness of the drug Leitragin, a solution for inhalation, for the treatment of severe pulmonary complications in patients with coronavirus infection (SARS-COVID-19);
  3. To study the effectiveness of the drug Dalargin, a solution for intravenous and intramuscular administration, for the prevention of severe pulmonary complications in patients with coronavirus infection (SARS-COVID-19);
  4. To study the effectiveness of the drug Dalargin, a solution for intravenous and intramuscular administration, for the treatment of severe pulmonary complications in patients with coronavirus infection (SARS-COVID-19);
  5. To evaluate the safety and tolerability of the use of the drug Leitragin, a solution for inhalation administration, for the prevention of severe pulmonary complications in patients with coronavirus infection (SARS-COVID-19);
  6. To evaluate the safety and tolerability of the use of the drug Leitragin, a solution for inhalation administration, for the treatment of severe pulmonary complications in patients with coronavirus infection (SARS-COVID-19);
  7. To evaluate the safety and tolerability of the use of the drug Dalargin, a solution for intravenous and intramuscular administration, for the prevention of severe pulmonary complications in patients with coronavirus infection (SARS-COVID-19);
  8. To evaluate the safety and tolerability of the use of the drug Dalargin, a solution for intravenous and intramuscular administration, for the treatment of severe pulmonary complications in patients with coronavirus infection (SARS-COVID-19).

Upon admission to a specialized hospital for all patients with suspected COVID-19 Polymerase chain reaction (PCR) is being conducted. Only patients with confirmed coronavirus infection are included in the study.

It is an open, randomized clinical trial of the drug Dalargin in combination with Leitragin for the prevention and treatment of severe pulmonary complications symptoms in patients with coronavirus infection (SARS-COVID-19)
