  Purpose
The objective of this study was to estimate the effects of a single dose of vardenafil on the blood pressure (BP) in subjects receiving maraviroc (MVC) (dosed to steady-state) and to assess the safety and tolerability of MVC in subjects receiving a single dose of vardenafil.

Condition Intervention Phase

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single (Participant)

Primary Outcome Measures:
  • Standing and Supine Systolic and Diastolic Blood Pressure (BP) [ Time Frame: 1.5, 2, 2.5, 3, 4, 6, 8, 12 hours post Vardenafil or Placebo dose ]
    Supine BP was taken after subjects rested for 5 minutes supine. Subjects then sat for 2 minutes and stood for 2 minutes then standing BP taken. Duplicate supine and standing BP measurements were taken per the protocol. The average of the duplicate measurements was calculated prior to data analysis.


Secondary Outcome Measures:
  • Standing and Supine Pulse Rate [ Time Frame: 1.5, 2, 2.5, 3, 4, 6, 8, 12 hours post Vardenafil or Placebo dose ]
    Supine pulse rate measurement was taken after subject rested for 5 minutes supine. Subject sat for 2 minutes, then stood for 2 minutes and standing measurement taken. Duplicate supine and standing pulse rate measurements taken per protocol. Average of duplicate measurements calculated prior to data analysis.

  • Postural Changes in Systolic and Diastolic Blood Pressure [ Time Frame: Baseline, 6 and 12 hours post dose on Day 1 from the First Day of each Treatment Leg ]
    Postural change calculated as position 1 (standing) value minus the position 2 (supine) value. Baseline was the average of 3 predose measurements at each period. Means of replicates were used in calculations.

  • Postural Changes in Pulse Rate [ Time Frame: Baseline, 6 and 12 hours post dose on Day 1 from the First Day of each Treatment Leg ]
    Postural change calculated as position 1 (standing) value minus position 2 (supine) value. Baseline was the average of the 3 predose measurements at each period. Means of Replicates were used in calculations.

  • Number of Subjects With Postural Hypotension [ Time Frame: Period 1 and Period 2 (up to 8 days) ]
    Postural (orthostatic) hypotension defined as 1) decrease in standing-supine diastolic blood pressure (BP) greater than or equal to 10 mm Hg; 2) decrease in standing-supine systolic BP greater than or equal to 20 mm Hg; or 3) standing systolic BP less than 90 mm Hg. Assessed at Period 1 and Period 2 BP measurement timepoints post maraviroc dose.
