Оценить эффективность и безопасность терапии нарлапревиром (НВР) в комбинации с ритонавиром (РТВ), пегилированным интерфероном (пег-ИФН) и рибавирином (РБВ) у первичных и ранее леченных больных хроническим гепатитом С, вызванным вирусом 1-го генотипа, без цирроза печени в двойном слепом плацебо-контролируемом III фазы исследовании (PIONEER). Материал и методы. В исследуемой группе НВР (200 мг внутрь один раз в сутки) назначали в сочетании с РТВ (100 мг) и пег-ИФН/РБВ в течение 12 нед с последующим долечиванием пег-ИФН/РБВ в течение 12 нед. Больные из группы сравнения получали пег-ИФН/РБВ в течение 48 нед, первые 12 нед в сочетании с плацебо. Результаты. Устойчивый вирусологический ответ через 24 нед после окончания лечения (УВО24) в исследуемой группе (НВР/РТВ, пег-ИФН/РБВ) был зарегистрирован у 89,1% (163/183) первичных и 69,7% (69/99) ранее леченных больных. УВО24 удалось достичь у 86,5% (32/37) больных с рецидивом после предшествующего курса терапии пегИФН/РБВ. Снижение вирусной нагрузки составило в среднем 5,3 log10 через 2 нед и 5,9 log10 через 4 нед терапии в группе НВР/РТВ, пег-ИФН/РБВ по сравнению с 1,5 log10 через 2 нед и 2,5 log10 через 4 нед лечения в группе сравнения. Среди первичных пациентов, получавших оцениваемую терапию, УВО24 был достигнут у 90,8% при исходной степени фиброза печени F0-F2 (по METAVIR) и у 75% при степени фиброза F3. Среди больных, ранее леченных пег-ИФН/РБВ, в исследуемой группе УВО24 зарегистирован у 72,6% с исходной степенью фиброза F0-F2 и у 53,3% с фиброзом степени F3. Добавление НВР/РТВ к терапии пег-ИФН/РБВ не приводило к ухудшению профиля безопасности по сравнению с таковым в группе больных, получавших терапию пег-ИФН/РБВ. Выводы. В исследовании PIONEER комбинированная терапия с нарлапревиром характеризовалась высокой эффективностью, удобством применения и улучшенным профилем безопасности.</p></abstract><trans-abstract xml:lang="en"><p>Aim of investigation. To estimate efficacy and safety of narlaprevir (NVR) with ritonavir (RTV), pegilated interferon (peg-IFN) and ribavirin (RBV) at treatmentnaïve and earlier treated noncirrhotic patients with chronic hepatitis C caused by the 1st virus genotype in double blind placebo-controlled 3rd phase study (PIONEER). Material and methods. The main group received NVR (200 mg od orally) in combination to RTV (100 mg) and pegIFN/RBV for 12 weeks that was followed by peg-IFN/ RBV for 12 weeks. Comparison group received pegIFN/ RBV for 48 weeks, for the first 12 weeks in combination to placebo. Results. The sustained virologic response in 24 weeks after treatment termination (SVR24) in the main group (NVR/RTV, PEG IFN/RBV)) was achieved in 89.1% (163/183) of treatment-naïve and 69.7% (69/99) of earlier treated patients. SVR24 was achieved in 86.5% (32/37) of patients with relapse after previous peg-IFN/ RBV treatment course. The viral load decreased for the mean of 5.3 log10 in 2 weeks and 5.9 log10 in 4 weeks of treatment in the main group vs 1.5 log10 in 2 weeks and 2.5 log10 in 4 weeks in comparison group. In treatment-naïve patients from the main group SVR24 was achieved in 90.8% at initial METAVIR F0-F2 liver fibrosis stage and in 75% at F3 liver fibrosis stage. In those who were previously treated by peg-IFN/RBV, in the main group SVR-24 was attained in 72.6% at liver fibrosis stage F0-F2 and in 53.3% with F3 liver fibrosis stage. NVR/RTV addition to peg-IFN/RBV treatment did not alter safety profile as compared to peg-IFN/RBV therapy. Conclusions. In PIONEER study the narlaprevir combination therapy was characterized by high efficacy, convenience of administration and favorable safety profile.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический гепатит С</kwd><kwd>лечение</kwd><kwd>нарлапревир</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Stanaway J.D. et al.
