E.5 End points |
E.5.1 | Primary end point(s) |
The study is aimed to determine whether the efficacy of Aesculus Hippocastanum L. seed extract exceeds the efficacy of maintenance treatment in the control group of SARS-CoV-2 infected patients (Covid-19 disease) with mild pneumonia. The primary endpoint is the determination of the period during which the Covid-19 disease clinical symptoms are reduced, and the patient's condition improves. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Until the end of the clinical trial day 28. |
|
E.5.2 | Secondary end point(s) |
The clinical endpoints of the study, which require regular evaluation in relation to the primary clinic of COVID-19 disease in the assessment of general respiratory symptoms, were selected as secondary endpoints based on their established relevance in clinical practice. They are the following: 1. Changes in the patient's health condition (according to a 10-point scale) 2. Time to the negative SARS-CoV-2 test (RT-PCR) 3. Duration of pyrexia, normalization of body temperature, SpO2 records, and chest radiographic imaging data 4. Changes in expression of clinical symptoms and vital signs 5. Chest imaging picture data on Days 0, 14 (evaluated data of changes) 6. The number (percentage) of patients requiring adjuvant O2 therapy; Duration of oxygen therapy (average) 7. Patients requiring treatment in the intensive care department (percentage), requiring mechanical ventilation therapy (percentage) 8. Clinical laboratory evaluation: white blood cell count, haemoglobin level, platelet count, blood glucose concentration, serum total bilirubin, creatinine, ALT, AST, electrolytes (Na+, K+), C-reactive albumin, IL-6, TNF-alfa, ferritin over the study time. |
