CLINICAL AND ECONOMIC ANALYSIS OF GENETICALLY ENGINEERED BIOLOGICS CONSUMPTION BY PATIENTS WITH COVID-19

ABSTRACT

The aim of the article is a comparative clinical and economic assessment of genetically engineered monoclonal antibodies against interleukins in infectious diseases facilities in Volgograd region, reassigned to treat COVID-19 patients. Materials and methods. ABC analysis of the drug consumption in infectious disease facilities in Volgograd region in 2020 and 2021, cost-minimization analysis, and volume of consumption (standard dose per 1000 patients) for genetically engineered monoclonal antibodies against interleukins, were performed on the basis of pharmacies dispensing drug reports on infectious diseases facilities, Russian State Register of maximum selling prices, and Russian guidelines for COVID-19 treatment. Results. Only a small proportion of COVID-19 patients (43.6 standard doses per 1000 patients in 2020 and 137.8 per 1000 patients in 2021) received genetically engineered biologics in infectious disease facilities in Volgograd Region. Nevertheless, in the studied facilities, medical drug expenses on them exceeded from 20% in 2020 to 40% of the total inventory value in 2021. In mild COVID-19 patients with a high comorbidity index, netaquimab was the least expensive drug therapy and levilimab was the most expensive one. For moderate COVID-19, a standart recommended dose of sarilumab was the least expensive among the drugs used in the studied facilities, and anakinra was the least expensive drug among all the recommended GEBs. In severe and extremely severe COVID-19 courses, tocilizumab and sarilumab were less the least expensive among the GEBs used in the infectious disease facilities, and anakinra was the least expensive among all the recommended GEBs. Conclusion. Accepting a possible equal effectiveness based on the currently available data, sarilumab is the least expensive for moderate COVID-19 and tocilizumab is the least expensive for severe and extremely severe COVID-19.
