| Phase 1 |
Detailed Description
This study is a double-blind, placebo-controlled, outpatient study of single oral ascending doses of Elsulfavirine to evaluate the safety, tolerability, and pharmacokinetics of Elsulfavirine and its active metabolite VM-1500A in HIV-negative, healthy subjects. Eight (8) subjects (6 active, 2 placebo) per dose level will be enrolled. Within each of the three cohorts consisting of 8 subjects, 6 subjects each will receive single oral doses of Elsulfavirine at 20 mg, 40 mg, or 80 mg in an escalating manner, and 2 subjects will receive matching placebo.
