Abstract

The given clinical review covers current antiviral therapy for chronic hepatitis C. Traditional antiviral therapy with pegylated interferon-α and ribavirin in patients with chronic hepatitis C virus genotype 1 allows a sustained virological response (SVR) to be achieved in no more than 40% of the treated patients. The practical introduction of the third component of the therapy as direct-acting antiviral agents makes it possible to substantially increase SVR, on the one hand, and to reduce treatment time, on the other hand. This review carefully analyzes the results of clinical trials of boceprevir (a new direct-acting antiviral agent and an NS3 serine protease inhibitor) that, when incorporated into an antiviral therapy regimen with pegylated interferons and ribavirin, considerably improves treatment results in patients with chronic hepatitis C virus genotype 1. Also, it discusses the safety and tolerance of drugs that belong to the class of hepatitis C virus serine protease inhibitors, as well as the problem of viral resistance.

Боцепревир: новые возможности противовирусного лечения хронического гепатита С. - Аннотация. В представленном клиническом обзоре освещается проблема современной противовирусной терапии хронического гепатита С. Традиционное противовирусное лечение с использованием пегилированного α-интерферона и рибавирина у пациентов с хроническим гепатитом С, инфицированных вирусом 1-го генотипа, позволяет достичь устойчивого вирусологического ответа (УВО) не более чем у 40% пролеченных пациентов. Внедрение в практику третьего компонента терапии в виде прямых противовирусных агентов, с одной стороны, позволяет существенно повысить УВО, с другой - сократить сроки лечения пациента. В представленном обзоре тщательно проанализированы результаты клинических исследований по препарату боцепревир (прямой противовирусный агент - ингибитор сериновой NS3-протеазы), который при включении в схему противовирусной терапии пегилированными интерферонами и рибавирином существенно улучшает результаты терапии у пациентов с хроническим гепатитом С, инфицированных вирусом 1-го генотипа. Кроме того, обсуждены вопросы безопасности и переносимости препаратов, относящихся к классу ингибиторов сериновой протеазы вируса гепатита С, а также проблема резистентности.
