An Open Non-comparative Study of the Efficacy and Safety of Aprotinin in Patients Hospitalized With COVID-19
Study Overview
Detailed Description
Primary objective of the study is to evaluate the efficacy of Aprotinin as add-on therapy in patients hospitalized with COVID-19 using the following parameters:
- The time to elimination of SARS-CoV-2 virus until Day 10;
- The time to C-reactive protein (CRP) normalization until Day 10;
- The time to D-dimer normalization until Day 10.
Secondary objectives are to evaluate the following parameters of efficacy and safety of Aprotinin add-on therapy in patients hospitalized with COVID-19:
- The time to body temperature normalization (<37oC);
- Changes from baseline of the laboratory parameters during 14 days: hematology, CRP, coagulogram;
- Changes of lung injury on CT scan on Day 7 and Day 14 from baseline;
- Frequency of clinical status improvement by 2 scores in accordance with the WHO Ordinal scale of clinical improvement (WHO-OSCI) or discharge from the hospital before Day 14;
- Frequency of transfer to the Intensive Care Unit (ICU), frequency of the non-invasive ventilation, frequency of the invasive ventilation and mortality rate;
- Frequency of Adverse Events (AEs) and Serious Adverse Events (SAEs) of various severity according to subjective complains, physical examination, vital signs, laboratory tests and ECG.

Description
Inclusion Criteria:

- Adult male or female ≥18 years of age;
- Body mass < 90 kg;
- Positive qualitative RNA SARS-CoV-2 PCR analysis at screening;
- Score 4 on the WHO-OSCI (added at Stage 2);
Subjects with moderate-to-severe disease with the follow conditions and symptoms:
- Pneumonia;
- Fever > 38°C;
- Blood serum CRP > 10 mg/L.
- Agreement to use medically acceptable forms of birth control during the study (contraceptive with spermicide).
Exclusion Criteria:
Severe disease with one of the follow criteria:
- Respiratory rate > 35 per minute that doesn't decrease after body temperature reducing to normal or subfebrile level;
- Saturation ≤ 93% at rest;
- Partial pressure of arterial oxygen (PaO2) < 60 mmHg;
