      The primary objective of the study is to evaluate the efficacy of a single dose of OKZ (64&#xD;
      mg) vs placebo in addition to standard therapy in patients with severe SARS-CoV-2 infection&#xD;
      (COVID-19) at Day 29.&#xD;

    <textblock>
      1. Pilot phase: the first 100 patients will be randomized in two groups to receive OKZ or&#xD;
           placebo (50 patients per group). Early futility analysis will be performed based on the&#xD;
           results obtained in the pilot period after 100th patient completed Visit 29. Enrollment&#xD;
           will be paused after randomization of 100th patient, then interim analysis will be&#xD;
           performed when all 100 patients complete Visit Day 29 or discontinue the study.Based on&#xD;
           results of the pilot phase analysis the study could be stopped.&#xD;
&#xD;
        2. Pivotal phase: inclusion of patients until targeted sample size is reached and&#xD;
           performing final safety and efficacy analysis.&#xD;
&#xD;
      Maximum expected study duration for each patient is 62 days, including 2 days of screening, 1&#xD;
      day of study drug administration, and 59 days of follow-up.&#xD;
&#xD;
      The study will include following periods:&#xD;
&#xD;
        1. Screening period lasting up to 48 hours prior to Day 1. After signing the informed&#xD;
           consent by the patient or the legally acceptable representative or when prior consent of&#xD;
           the patient is not possible, and the subject's legally acceptable representative is not&#xD;
           available, after obtaining documented approval/favorable opinion for individual cases by&#xD;
           the Institutional Review Board / Independent Ethic Committee (IRB/IEC), investigator&#xD;
           will assess the subject's eligibility for the study.&#xD;
&#xD;
        2. Treatment period lasting from the beginning of Day 1 visit to 23:59 of the Day 1.&#xD;
&#xD;
           Eligible patients will be randomized to one of two treatment groups to receive a single&#xD;
           subcutaneous injection - OKZ 64 mg or placebo in addition to standard COVID-19 therapy&#xD;
           according to institutional guidelines;&#xD;
&#xD;
        3. Follow-up period lasting from 00:00 of the Day 2 to 23:59 of the Day 60. If the patient&#xD;
           is discharged earlier than Day 15, at Days 15 and 29 5-point clinical status scale will&#xD;
           be assessed at the study site visit or by phone interview. If the patient is discharged&#xD;
           after Day 15, but earlier than Day 29, at Day 29 5-point clinical status scale will be&#xD;
           assessed at the study site visit or by phone interview. The end of study is Day 60, when&#xD;
           5-point clinical status scale will be assessed by phone interview.&#xD;
&#xD;
      Up to 376 randomized patients (full sample size) will be included in the study according to&#xD;
      preliminary estimation.&#xD;
