ABSTRACT

Aim - to evaluate the efficacy and safety of olokizumab in hospitalized patients with moderate to severe coronavirus disease COVID-19. Material and methods. A multicenter non-interventional retrospective study of olokizumab treatment in hospitalized patients with COVID-19 was conducted. The initial population in this study included 2926 patients with COVID-19. Patients with moderate or severe disease who were taking corticosteroids as part of standard therapy were selected for this analysis. The final population was 1738 patients. A test group (standard therapy: corticosteroids, antiviral, pathogenetic or symptomatic therapy in combination with olokizumab) and a comparison group (standard therapy only) were formed. Each group included 869 patients. The primary end point was all-cause mortality from the start of anti-inflammatory therapy to the end of follow-up. We also analyzed the incidence of transfer and the length of stay of patients in the intensive care unit, the duration of hospitalization, as well as the change in C-reactive protein level. Results and discussion. It was found that olokizumab significantly reduces the all-cause mortality compared with standard therapy: 54 (6.21%) cases compared with 111 (12.77%) in the control arm, p<0.001, odds ratio (OR) 2.21 [1.57;3.1]. The results of factor analysis confirmed that olokizumab increases the odds of recovery, OR 2.41 (95% CI 1.64-3.54, p<0.001). In addition, patients in olokizumab group showed significantly lower plasma CRP levels compared with control group. Already on the 2nd day after the start of therapy the CRP level was almost 2 times lower in the olokizumab group than in the control group (the median was 13 [5.6;28.55] mg/l and 25 [15.3;79.25] mg/L in the olokizumab and comparison groups, respectively). Conclusion. The results of the study confirm the clinical data on the efficacy of olokizumab as therapy for COVID-19 patients.Copyright © 2022 Tomsk Polytechnic University, Publishing House.

ABSTRACT

Currently, there are data that that make it possible to speak about a high clinical efficacy of the use of succinic salt of tyrosylD-alanyl-glycyl-phenylalanyl-leucyl-arginine (hexapeptide succinate) for the COVID-19 treatment. This article is devoted to the results of clinical trials of the original Russian drug based on it. The aim of the study was to evaluate a clinical efficacy, safety and tolerability of intramuscular and inhalation use of hexapeptide succinate in complex therapy in comparison with standard therapy in patients with moderate COVID-19. Materials and methods. The research was conducted from February 28, 2022 to November 22, 2022 based on 10 research centers in the Russian Federation. The study included hospitalized patients (n=312) over 18 years of age with moderate COVID-19 who had undergone a screening procedure and were randomized into 3 groups: group 1 received standard therapy in accordance with the Interim Guidelines in force at the time of the study, within 10 days;group 2 received hexapeptide succinate (Ambervin Pulmo) intramuscularly at the dose of 1 mg once a day for 10 days;group 3 received hexapeptide succinate (Ambervin Pulmo) 10 mg once a day by inhalation for 10 days. Results. According to the results of the study, therapy with the drug hexapeptide succinate, both intramuscular and inhaled, provided an acceleration of recovery up to the complete absence of the disease signs in more than 80% of hospitalized COVID-19 patients. By the end of the therapy course with the drug, more than 60% of patients had met the criteria for discharge from hospital and could continue the treatment on an outpatient basis. About 70% of patients in the inhalation group and 80% in the intramuscular hexapeptide succinate injection group had concomitant diseases (hypertension - 28%, obesity - 14%), which indicates the effectiveness of this drug use in comorbid patients. The use of the drug contributed to the restoration of damaged lung tissues, normalization of oxygenation, the disappearance of shortness of breath and a decrease in the duration of the disease symptoms compared with standard therapy. As a result of a comparative analysis of adverse events in terms of their presence, severity, causal relationship with the therapy and outcome, there were no statistically significant differences between the treatment groups. Conclusion. Thus, the results of the clinical study of the succinate hexapeptide efficacy and safety showed the feasibility of using the drug in pathogenetic therapy COVID-19 regimens.Copyright © 2022 Volgograd State Medical University, Pyatigorsk Medical and Pharmaceutical Institute.

ABSTRACT

Favipiravir has demonstrated efficacy against the SARS-CoV-2 virus in several preliminary studies. This study aimed to evaluate the efficacy and safety of favipiravir for treatment of mild to moderate COVID-19 in outpatients and hospitalized patients. We conducted an open-label, randomized, active-controlled trial of a generic form of favipiravir in patients with COVID-19 confirmed by PCR-test. Eligible patients (18-60 years) after stratification were randomly assigned (in a 2:1 ratio) to receive either favipiravir (1800 mg BID on day 1, followed by 800 mg BID for up to 9 days), or standard of care (SOC) treatment (umifenovir + intranasal interferon alpha-2b, or hydroxychloroquine) for up to 10 days. The co-primary outcomes were the time to clinical improvement and the time to viral clearance. Among 190 patients assessed for eligibility 168 were randomized to favipiravir (n=112) or to SOC (n=56) group. The median time to clinical improvement was 6.0 days (IQR 4.0;9.3) in the favipiravir group and 10.0 (IQR 5.0;21.0) days in the SOC group;the median difference was 4 days (HR 1.63;95% CI 1.14-2.34;P=0.007). The statistically significant difference in the median time to viral clearance was observed only for hospitalized patients: 3.0 (IQR 3.0;3.0) days in the favipiravir group vs. 5.0 (IQR 4.5;5.5) days in the SOC group (HR 2.11;95% CI 1.04-4.31;P=0.038). The rate of viral elimination on Day 5 in the favipiravir group was significantly higher than in SOC group: 81.2% vs. 67.9% (RR 1.22;05% CI 1.00-1.48;P=0.022). The rate of clinical improvement on Day 7 in the favipiravir group was 1.5-fold higher than in SOC group: 52.7% vs. 35.8% (RR 1.50;95% CI 1.02-2.22;P=0.020). Favipiravir was well-tolerated and the most common adverse reactions were asymptomatic hyperuricemia, transient elevation of ALT & AST, and mild gastrointestinal disorders. Favipiravir was superior to the SOC in shortening the time to clinical improvement in patients with mild to moderate COVID-19.
