简要总结
The primary objective of the study is to evaluate the efficacy and safety of Artlegia (INN: olokizumab) new dosing regimen in patients with moderate coronavirus infection (COVID-19) with signs of hyperinflammation.
This study is a multicentre, open-label, randomized, comparative, parallel group, active-controlled clinical trial.
详细描述
The study has an adaptive design. According to the initial calculation of the sample size it was planned to include about 204 patients in the study. After interim analyzing of the data of the first 100 randomized patients a decision about the final sample size was made. The size of the intent-to-treat (ITT) population for the final efficacy analysis at the primary endpoint is 180 patients. Taking into account the probability of dropping out up to 10% of patients, 198 patients were planned to be randomized into the study, no more than 220 patients were planned to be screened.
The study will include the following periods:
- Screening period lasting up to 2 days (days -1-0). During this period patient's eligibility assessment will be performed;
- Treatment period: up to 10 days. Treatment period starts from the end of the screening (days 1-10) and includes randomization following by a 10 days of standard therapy with or without olokizumab and patient monitoring (laboratory tests, electrocardiogram (ECG), chest computed tomography (CT));
- Short-term follow-up period up to 28 days (days 11 through 28). It includes procedures of patient monitoring (laboratory tests, ECG, chest CT) on days 14 (± 2) and 28 (± 2).
- Long-term follow-up period: up to 180 days (days 29 through 180). Includes telephone contacts with the patient on days 45, 60, 90 and 180.
Eligible patients will be randomized to one of 2 treatment groups to receive olokizumab (OKZ) 128 mg i.v. infusion (one or two single doses) against the background of standard therapy, or standard therapy alone.
In OKZ group study drug olokizumab 128 mg is administered as a single intravenous infusion. A comprehensive assessment of the clinical and laboratory response is performed daily within 5 days (120 hours) after the first injection. If there is no response to therapy or the response is insufficient, the repeated dose of OKZ, 128 mg, is administered.

结局指标
主要结局
Clinical recovery rate at day 7
时间窗: Up to day 7
Clinical recovery defined as score of 3 or less on a 10-point ordinal scale of clinical improvement. (From 0 "Healthy - no clinical manifestations, no viral RNA detected" to 10 "Death".) 7 days are counted from the day of the first administration / intake of study therapy / comparison therapy, depending on study group. Criteria for transition from category "4" to category "3" (criteria for potential discharge): body temperature \< 37 °C; respiratory rate ≤ 20 per minute; SpO2 ≥ 95% without oxygen support, CRP \< 10 mg/l. If any emergency procedures should be prescribed and/or signs of progression on CT are detected, the patient cannot be discharged/transferred to category "3". (In the case of the "rescue" therapy use or the development of clinical deterioration (an increase in the score by 1 point or more) during the follow-up period in a previously recovered patient, the patient is not considered as a "responder", i.e., who has reached the primary endpoint.)
