Primary Outcome Measures:
  • Safety and tolerability of GSK580416 doses determined from clinical safety and tolerability data from all adverse event reporting, 12-lead ECGs, vital signs, nursing/physician observation, and safety laboratory tests

Secondary Outcome Measures:
  • Pharmacokinetics of GSK580416 as determined by AUC, Cmax, tmax, half-life, and Ct.

Estimated Enrollment: 96
Study Start Date: June 2007
Detailed Description:
A three part study in healthy adult subjects to evaluate the safety, tolerability and pharmacokinetics of repeat escalating oral doses of GSK580416; the safety, tolerability, and pharmacokinetics of GSK580416 following a loading dose regimen; and the effect of ketoconazole on the pharmacokinetics of GSK580416
