Study to Evaluate Pharmacokinetic and Safety of Albuvirtide Between Intravenous Drip and Intravenous Injection

30 Chinese volunteers will be enrolled to assess the pharmacokinetic and safety of Albuvirtide in two different Administration methods. All subjects are required to collect PK blood samples before and after administration.

30 healthy subjects will be randomized into three cohorts ( cohorts A, B and C) in 1:1:1 ratio, with 10 subjects in each cohort. The subjects will receive a single dose of 320 mg of albuvirtide by iv infusion for 45 min or by iv bolus for 0.5 min or 3 min, respectively.
