Brief summary

This is a Phase I, randomized, double-blind, placebo-controlled, sequential-panel, ascending single-dose, single-center study to evaluate the safety and tolerability, and describe the pharmacokinetics of escalating single doses of CMX-020 administered as a 15-minute intravenous infusion to healthy male and female subjects. The study population will be comprised of up to 48 healthy male and female subjects aged 18-50 years, inclusive, considered eligible on the basis of study inclusion and exclusion criteria. Each subject who meets eligibility criteria will be randomly assigned to receive CMX-020 or placebo. Each escalating dose group will consist of 8 subjects; 6 will be randomized to receive a single dose of CMX-020, and 2 will be randomized to receive a single dose of placebo. Treatment groups will be dosed in an escalating order, each dose level increased by no more than 2-fold over the previous dose level. The decision to escalate the dose will be based upon review of the safety and EEG data for all subjects in each previous dosing panel. No subject will receive more than one dose of study medication.

Interventions

Up to six (6) dose levels with approximately two weeks between the dosing of each group. In total of 6 cohorts: Cohort 1: CMX-020 drug- 0.02 (mg/kg) - Single Intravenous infusion over 15 min Cohort 2: CMX-020 drug- 0.04 (mg/kg) - Single Intravenous infusion over 15 min Cohort 3: CMX-020 drug- 0.08 (mg/kg) - Single Intravenous infusion over 15 min Cohort 4: CMX-020 drug- 0.16 (mg/kg) - Single Intravenous infusion over 15 min Cohort 5: CMX-020 drug- 0.24 (mg/kg) - Single Intravenous infusion
