Overview

The study purpose was to assess the outcomes of therapy with olokizumab within complex therapy of Coronavirus disease 2019 (COVID-19) in hospitalised patients in real clinical practice setting. The study investigated patients' characteristics, disease progression, and efficacy and safety of olokizumab therapy.

This was a multicentre retrospective cohort study of patients admitted to hospitals in various Russian Federation cities with positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid (RNA) laboratory test for the treatment of severe acute respiratory syndrome. The study used information from primary medical documentation of COVID-19 patients who had underwent diagnostic and therapeutic procedures in accordance with the hospital clinical practice. Clinical and laboratory data was collected and analysed to assess olokizumab safety, investigate other treatments, course and outcomes of the disease. No additional tests or medical procedures were made as part of this study. If any data collected under the protocol was not available or not collected, they deemed lacking. Based on the results of preliminary assessment of the number of records from the patients meeting inclusion / exclusion criteria in the clinical sites planning to participate in the project it was planned to include no more than 3000 patients in the study, of which about 1500 would be in the main group (received olokizumab therapy), and 1500 would be in the comparison group. It was planned to conduct an analysis in the general population (including taking into account its balancing using statistical methods, in case of significant differences in the initial characteristics of patients in groups), as well as in a subpopulation selected from pairs formed taking into account the comparability of patients by individual characteristics. In total, it was planned to form at least 200 pairs (or more, if the included population is highly comparable). Participation of several clinics in Russian Federation cities (not more than 10 cites) was expected to assure sufficient population for the study. Data collection period for each hospitalised patient was equivalent to in-hospital period for the treatment of SARS-CoV-2 infection. Data collection by patients was made during hospital stay, including the day of discharge (treatment outcome or lethal outcome). The primary study variables were defined during 21-day observation period.

Outcomes

Primary Outcomes

The percentage of patients who died during hospital admission due to any reason

The percentage of patients who died during hospital admission due to any reason in each therapy group

Time frame: up to 21 days

Secondary Outcomes

The percentage of patients who required mechanical ventilation or transfer to intensive care unit (ICU), or who died during hospital admission due to COVID-19

The percentage of patients who required mechanical ventilation or transfer to ICU, or who died after olokizumab therapy during hospital admission due to COVID-19.

Time frame: up to day 21

The percentage of patients who required transfer to ICU

The percentage of patients who required transfer to ICU in each therapy group

Time frame: up to day 21

The percentage of patients who required transfer to a new type of oxygen support and to an invasive mechanical ventilation (MV)

The transfer to a new type of oxygen support means the transfer to a more severe type of oxygen support (the appointment of low-current oxygen to patients who were initially without oxygen support; transfer from low-flow oxygen therapy to high-flow, non-invasive or invasive ventilation; from high-flow oxygen therapy to non-invasive or invasive ventilation; from non-invasive to invasive ventilation).

Time frame: up to day 21

Overall hospitalisation period

Overall hospitalisation period duration in each therapy group (in days)

Time frame: from admission to discharge from hospital, up to 21 days
