Study Overview
Brief Summary
This is open label, phase 1 clinical study to evaluate the safety, tolerability and pharmacokinetics of Elpida® in healthy subjects and patients with hepatic impairment (Child - Pugh Class А and B), as well as to assess the impact of food intake and drug-drug interactions in case of Co-administration with other antiviral drugs in healthy subjects.
Detailed Description
In medical practice HIV infection is often found associated with viral hepatitis, especially chronic hepatitis C virus (HCV). This, as well as a possible change in PK parameters in case of co-administration of Elpida® and HIV integrase inhibitors, necessitates the study of PK and safety of co-administration of Elpida® with a combination of Sofosbuvir + Daclatasvir and Dolutegravir in healthy subjects. Thus, the study to evaluates safety and pharmacokinetics of Elpida® in healthy subjects and patients with hepatic impairment, as well as assesses the impact of food intake and drug-drug interactions in case of co-administration with other antiviral drugs in healthy subjects.
