Analysis of the experience with once-weekly intramuscular administration of interferon beta-1a in the Russian population of patients with relapsing-remitting multiple sclerosis

Le résumé fourni par la source

SinnoVex is a drug from the group of bioanalogues of interferon beta-1a for intramuscular administration, which has moderate efficacy in reducing clinical exacerbations of multiple sclerosis (MS), which is most pronounced in the initial treatment of relapsing-remitting MS (RRMS) with low or moderate disease activity. Objective: to analyze the experience with the use of the drug SinnoVex in several parallel studies in the Russian population of patients with RRMS. Material and methods. We analyzed the results of three retrospective post-marketing clinical trials, in which we compared the efficacy and safety of the use of interferon beta-1a for once-weekly intramuscular administration under the trade name SinnoVex in the treatment of the Russian population of patients with RRMS with other MS disease-modifying treatments (DMTs), in particular with high-dose interferons beta-1a and interferons beta-1b for subcutaneous administration. The total number of patients who received therapy with SinnoVex was 235 subjects. The efficacy of the therapy was assessed using the following indicators: average annual frequency of exacerbations, MRI activity, achievement of the NEDA-3 indicator. The safety of the therapy was evaluated based on the occurrence of adverse events (AEs) and their severity as well as the frequency of discontinuation of the drug. Results. Based on the results of the studies presented, no statistically significant differences in the clinical efficacy or tolerability of the intramuscularly administered SinnoVex preparation compared to other drugs of the interferon beta group were found. The spectrum and severity of AEs were in line with expectations; no unexpected AEs were observed. Conclusion. Among the important advantages of the drug are the relatively rare intramuscular injections and rare local skin AEs after injections, which significantly increase the benefit of the drug in young patients. In this regard, SinnoVex is most commonly used as an initial drug as part of an escalation approach to the treatment of RRMS and then needs to be replaced by more highly effective firstor second-line DMTs if efficacy is insufficient.
