Primary Outcome Measures
NameTimeMethod
Absorption rate of the tablet formulations as measured several times by blood draws (over 48-hour period) during the Part 1 under fed conditions and Part 2 under fed vs. fasted conditions
Secondary Outcome Measures
NameTimeMethod
Toleration of the formulations after single and repeat doses (over 7-day period)
Part 1: Safety and tolerability assessments will include data from spontaneous adverse event reporting, vital signs, 12-lead ECGs, physical examinations, and safety laboratory tests.
Part 2: Safety and tolerability assessments will include data from spontaneous adverse event reporting, vital signs, 12-lead ECGs, physical examinations, and safety laboratory tests.
Part 2: The secondary pharmacokinetic parameters will be the AUC, Cmax, Tmax, and T1/2 following repeat oral dosing of Solabegron, as the data permit.
