36 healthy adult men and women will be enrolled with the goal of having 24 subjects complete the entire study. The study will consist of a pre-treatment phase and a treatment phase.

A baseline period will precede each treatment period. The screening period will be up to 13 days in duration. After fulfilling screening requirements, subjects will check into the clinic on Day -1 for baseline assessments. They will be domiciled in the clinical testing facility for 6 days for Treatment Periods 1, 3, and 4 and will return intermittently for study procedures for 8 outpatient visits.
