NCT00955396
First received: August 6, 2009
Last updated: January 7, 2010
Last verified: January 2010
  Purpose

In this study the investigators will determine whether there is any effect of GSK1014802 on ambulatory blood pressure. This will be a randomized, double-blind, placebo-controlled, repeat dose, 2 period cross-over study conducted in healthy male and female subjects. Approximately 60 subjects will be randomised to receive GSK1014802 400 mg bid and placebo for 36 days with at least 1 week between treatment sessions. A follow-up will occur 7-14 days after the last dose.

Primary Outcome Measures:
  • Change in 24 h average SBP and DBP from Baseline to Day 36. [ Time Frame: 36 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Change in 24 h average SBP and DBP from Baseline to Day 15. Change in average SBP and DBP within a dosing interval (12 h) from Baseline to Days 14 and 35. [ Time Frame: 35 days ] [ Designated as safety issue: Yes ]
  • Change in 24 h average SBP and DBP from Baseline to Days 15 and 36 in subjects with baseline SBP 120-139 mmHg and also DBP 80-89 mmHg. [ Time Frame: 36 days ] [ Designated as safety issue: Yes ]
  • Change in day-time outpatient (6:00 AM to 10:00 PM) SBP and DBP from Baseline to Days 15 and 36. [ Time Frame: 36 days ] [ Designated as safety issue: Yes ]
  • Change in night-time outpatient (10:00 PM to 6:00 AM) SBP and DBP from Baseline to Days 15 and 36. [ Time Frame: 36 days ] [ Designated as safety issue: Yes ]
  • Change in 24 h average ambulatory heart rate from Baseline to Days 15 and 36. [ Time Frame: 36 days ] [ Designated as safety issue: Yes ]
  • Proportion of patients whose 24 h systolic and diastolic BP increased by < 5, 5-9, 1014, 15-19, and > 20 mm Hg compared to baseline. [ Time Frame: 36 days ] [ Designated as safety issue: Yes ]
  • PK parameters of GSK1014802 following a single oral dose of GSK1014802 to healthy female subjects: Cmax, tmax, AUC (0-t) and, if possible, AUC(0-∞), λz and terminal phase half-life to healthy female subjects. [ Time Frame: 1 day ] [ Designated as safety issue: No ]
  • PK parameters of GSK1014802 following repeated oral doses of GSK1014802 given twice daily to healthy male and female subjects: Cmax, tmax, AUC(0-12). [ Time Frame: 36 days ] [ Designated as safety issue: No ]
  • PK/PD analyses to examine the correlation between ambulatory blood pressure and plasma levels and/or metrics of the systemic exposure (Cmax, AUC) of GSK1014802. [ Time Frame: 36 days ] [ Designated as safety issue: No ]
