What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Standing and Supine Systolic and Diastolic Blood Pressure (BP)

    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.

    Measured: 1.5, 2, 2.5, 3, 4, 6, 8, 12 hours post Vardenafil or Placebo dose

Secondary outcomes (4)
  1. Standing and Supine Pulse Rate

    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.

    Measured: 1.5, 2, 2.5, 3, 4, 6, 8, 12 hours post Vardenafil or Placebo dose

  2. Postural Changes in Systolic and Diastolic Blood Pressure

    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.

    Measured: Baseline, 6 and 12 hours post dose on Day 1 from the First Day of each Treatment Leg

  3. Postural Changes in Pulse Rate

    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.

    Measured: Baseline, 6 and 12 hours post dose on Day 1 from the First Day of each Treatment Leg

  4. Number of Subjects With Postural Hypotension

    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.

    Measured: Period 1 and Period 2 (up to 8 days)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Maraviroc and Vardenafil in people with AIDS, run by ViiV Healthcare at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Jun 2009). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jan 2013.
