The Advisory Board chaired by the chief specialist in infectious diseases of the Ministry of Health of Russian Federation, Professor V.P. Chulanov was held on June 18, 2022 in Saint Petersburg. Aim. The main purpose of the Board was following discussion: the analysis of the real-world data of levilimab as an anticipatory therapy for COVID-19 in hospitalized patients; the review of the experience and perspectives of levilimab as an anticipatory anti-inflammatory option for outpatient patients who meet defined clinical and laboratory criteria. Results. The analyzed data on clinical efficacy and safety formed the basis of recommendations proposed by experts for the use of levilimab in the inpatient and outpatient medical care for COVID-19.

BACKGROUND: The use of virus-neutralizing monoclonal antibodies is an effective method of etiotropic therapy for SARS-CoV-2 in patients of high-risk groups of severe COVID-19. Regdanvimab is a single-component monoclonal antibodies immunoglobulin G1, whose mechanism of action is aimed at binding SARS-CoV-2 virus at the RBD site of the spike protein S1 domain. In the Russian Federation, regdanvimab is approved for emergency administration in COVID-19 for adult patients not requiring respiratory therapy who are at high risk of developing a severe course of the disease. AIM: To evaluate the efficacy and safety of therapy with regdanvimab in patients with mild/moderate COVID-19 in a short-term hospital unit. MATERIALS AND METHODS: Virus-neutralizing therapy with regdanvimab was performed at the short-term hospital unit of the Moscow City Clinic. An open retrospective observational single-center study included 92 adult patients with mild/moderate coronavirus infection. All patients had comorbid chronic diseases and belonged to the high-risk group for the development of a severe COVID-19. INCLUSION CRITERIA: age 18 to 75 years; presence of a verified diagnosis of COVID-19 of mild/moderate COVID-19, polymerase chain reaction (PCR) confirmed; one or more chronic diseases; first 7 days from the onset of the first symptoms of COVID-19 (including day 7). EXCLUSION CRITERIA: need for oxygen support. Clinical efficacy was assessed according to the World Health Organization Сlinical Progression Scale and supplemented with laboratory markers at baseline and in dynamics, as well as with monitoring of virus elimination by PCR. STATISTICS: Calculations were performed using the statistical computing environment R 4.1.3 (R Foundation for Statistical Computing, Austria). For quantitative indices the median (1; 3 quartiles) was indicated. For binomial signs we calculated 95% confidence intervals according to Wilson's method. Time interval analysis was performed according to the KaplanMeier method. The significance level was determined at p0.05. RESULTS: A significant decrease in the severity of clinical manifestations according to the World Health Organization Clinical Progression Scale was noted by patients by day 4 after regdanvimab administration. All 92 patients in the cohort were discharged from the hospital l on average on day 5 after regdanvimab administration and on day 9 of the disease. On day 4 after drug administration 82% of patients was being PCR negative. No adverse events related to the administration of regdanvimab were reported during the study. CONCLUSION: In real clinical practice, the efficacy and safety of regdanvimab in patients at high risk of severe COVID-19 was confirmed once again, with a positive clinical result observed in a mixed cohort by the causative agent omicron and delta strain.

AIM: To study the effect of levilimab or baricitinib in combination with standard therapy (ST) on the incidence of severe viral pneumonia associated with a new coronavirus infection COVID-19. MATERIALS AND METHODS: A multicenter, open-label observational study of the efficacy and safety of levilimab in combination with ST (group 1, n=100), baricitinib in combination with ST (group 2, n=139), or in comparison with ST (group 3, n=200) in outpatients with verified CT-1 pneumonia. RESULTS: According to the results of laboratory tests, patients treated with levilimab in combination with ST had the best dynamics of changes in CRP from reliably the highest level (mg/L) to the lowest in comparison with other groups. In the group of patients with ST, in contrast to the other groups, no dynamics of CRP was observed by day 5 of therapy. In group of hospitalized patients initially receiving levilimab in addition to ST, the rate of transfer to the intensive care unit (2 patients, 9.52%) and length of stay (4 days) was significantly lower compared to the values in patients in both the baricitinib group in combination with ST (7 patients, 15.56%; 5 days [interquartile range 36.5]) and in patients receiving ST alone (7 patients, 15.56%; 5 days [interquartile range 36.5]). Also in hospitalized patients we observed no statistically significant intergroup differences in the incidence of infectious complications and thromboembolic events, which confirms the safety of including levilimab or baricitinib in COVID-19 pathogenetic therapy regimens. Observational results support the hypothesis that the initial inclusion of levilimab or baricitinib in addition to ST is accompanied by a reduced risk of viral pneumonia progression. CONCLUSION: The addition of levilimab or baricitinib to the therapy regimen for coronavirus infection during the outpatient phase has demonstrated a preemptive anti-inflammatory effect and reduced the probability of lung tissue damage progression.

AIM: To determine the criteria for the optimal use of IL-6 receptor blockers in patients with COVID-19 community-acquired pneumonia based on predictors of adverse outcomes. MATERIALS AND METHODS: The single-center, non-randomized prospective study included 190 patients with community-acquired pneumonia caused by coronavirus 2 between the beginning of March and the end of May 2020. Of these, 89 patients received tocilizumab and 101 patients received sarilumab. The study inclusion criterion for the patient was indications for initiating therapy with one of the inhibitors of IL-6 receptors (anti-IL-6R) according to the Interim guidelines (versions 4 and 5). The exclusion criterion was the need to re-prescribe genetically engineered biological therapy (GEBT). The severity of the patient's condition was assessed according to the early warning score (NEWS2), the volume of lung tissue lesions was assessed according to computed tomography (CT). Laboratory monitoring included counting the absolute (abs) number of lymphocytes, serum levels of C-reactive protein (CRP), interleukin 6 (IL-6), D-dimer, lactate dehydrogenase, fibrinogen. Statistical data processing was conducted by nonparametric methods using the IBM SPSS Statistics V-22 software. RESULTS: The phenotype of a patient with a negative outcome prognosis was described: a male patient over 50 years of age with aggravated premorbid background (with cardiovascular diseases, obesity and/or chronic renal disease), lung lesion CT 34, saturation less than 93% upon inhalation of atmospheric air, persisting for 2448 hours after GEBT. According to the blood test, lymphopenia was below 1000 U/L and CRP levels were above 50 mg/L. The laboratory parameters and clinical picture of the patient progressively worsened after 911 days of illness, regardless of the use of Anti-IL-6R. The features of patients monitoring when administering IL-6 receptor blockers have been determined. CONCLUSION: IL-6 receptor blockers should be administered to patients hospitalized with severe COVID-19 before the development of hyperinflammatory reactions. The optimal "therapeutic window" is 78 days of illness.
