Narlaprevir (formerly SCH 900518), a NS3 protease inhibitor is being developed by R-Pharm for the treatment of a chronic hepatitis C (genotype 1). Narlaprevir is a potent inhibitor of hepatitis C virus (HCV) NS3 protease with a Ki of 7 ± 1 nM and a 90% inhibitory concentration (IC90) of ∼28 ng/ml for HCV genotype 1 replicon in vitro. Narlaprevir successfully passed extensive pre-clinical and clinical trials in Schering-Plough Research Institute (USA) and in a variety of clinical centers of Europe, USA and Russia. Based on clinical findings R-Pharm obtained a registration certificate for Arlansa (Narlaprevir) ЛП-003622 dd 12.05.2016 issued by Ministry of Healthcare of the Russian Federation.

Sample Use Guides

In Vivo Use Guide

Narlaprevir at 200 mg was administered to 8 healthy and 8 cirrhotic subjects, and Narlaprevir at 100 mg with RTV at 100 mg was administered to 8 healthy and 8 cirrhotic subjects. In part 1 of the study, 8 patients with compensated cirrhosis and 8 matched healthy adult subjects received single doses of NVR at 200 mg with 240 ml of water after a standard breakfast. The 200-mg NVR dose was chosen since this is the intended therapeutic dose. This dose is the approved marketed dose of NVR for the treatment of CHC genotype 1 in the Russian Federation. In part 2 of the study, 8 patients with compensated cirrhosis and 8 healthy subjects received NVR at 100 mg in combination with RTV at 100 mg with 240 ml of water after a standard breakfast.
