PRIMARY outcome

Timeframe: 0 to 36 Hours Post Dose

Population: Pharmacokinetic (PK) results included complete data from 75 of 77 subjects (with 1 replacement). Partial data from 1 subject were not analyzed. Plasma concentrations for another subject were undetectable following 1 treatment, with partial data excluded from analyses.
