Aprotinin is a potent multi-target drug for the combination therapy of moderate COVID-19 cases
2020
Objectives. COVID-19 is a contagious multisystem inflammatory disease caused by a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We have studied the efficacy of Aprotinin (nonspecific serine proteases inhibitor) and Avifavir or Hydroxychloroquine (HCQ) combinations for the therapy of COVID-19. Methods. Three prospective single-center (cohorts 1 – 3) studies included participants with moderate COVID-19-related pneumonia, laboratory-confirmed SARS-CoV-2 and admitted to the hospitals. Patients received combinations of intravenous (IV) Aprotinin (1,000,000 KIU daily, 3 days) and HCQ (cohort 1), inhalation (inh) treatment with Aprotinin (625 KIU 4 times per day, 5 days) and HCQ (cohort 2) or IV Aprotinin (1,000,000 KIU daily for 5 days) and Avifavir (cohort 3). Results. In the cohorts 1 – 3, the combination therapy showed 100% efficacy in preventing the transfer of patients (n = 30) to the intensive care unit (ICU). The effect of combination therapy in the cohort 3 was the most prominent and the median time to SARS-CoV-2 elimination was 3.5 days (IQR 3.0 – 4.0), normalization of CRP concentration was 3.5 days (IQR 3 – 5), of D-dimer concentration - 5 days (IQR 4 – 5); body temperature - 1 day (IQR 1 – 3), improvement in clinical status or discharge from the hospital - 5 days (IQR 5 – 5), and improvement in lung lesions of patients on 14 day - 100%. Conclusions. The administration of Aprotinin combinations prevented the transfer of moderate COVID-19 patients to the ICU for mechanical ventilation (ALV) or non-invasive ventilation (NIV) and by shortening of their hospital stay.
