Objective: to confirm the efficacy and safety of levilimab in patients with rheumatoid arthritis (RA) switched from other interleukin 6 receptor inhibitors (iIL6R) for non-medical reasons.Patients and methods. A retrospective analysis of data from the register of patients with RA who during the COVID-19 pandemic were switched from foreign iIL6Rs to the Russian drug levilimab. Treatment regimens with levilimab in combination with synthetic diseasemodifying antirheumatic drugs (sDMARDs) and/or glucocorticoids (GCs) were used, as well as a monotherapy regimen in case of DMARDs intolerance.Results and discussion. In 150 patients with RA, a successful non-medical switch to levilimab was demonstrated with the preservation and intensification of the clinical effect achieved on previous therapy with iIL6R. After switching to levilimab, the DAS28-CRP index decreased by an average of 0.098 at 3 months and by 0.25 at 6 months (p=0.214 for both time points). There was a decrease in the proportion of patients with elevated levels of CRP, as well as with high RA activity. In a number of patients who showed high efficacy of levilimab, it became possible to reduce the dose or number of DMARDs, as well as cease GCs intake. Good tolerability and a favorable safety profile of levilimab were noted, including in relation to the new coronavirus infection that developed during therapy.Conclusion. Therapy with Russian iIL6R levilimab is effective and safe, including in patients switched from other drugs for non-medical reasons, as well as in relation to the novel coronavirus infection that developed during therapy.
