What is being measured

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

  1. Pulmonary artery mean pressure at rest

    Measured: Peak change from baseline within 6 hours after a single dose of study drug

Secondary outcomes (2)
  1. Adverse event collection

    Measured: until 30 days after study drug treatment

  2. Plasma concentrations to obtain pharmacokinetic profile of Riociguat

    Measured: Within 24 hours after study drug treatment

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted30 Jul 2010 (estimated)
  2. Study startJul 2010
  3. Primary completionOct 2012

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Riociguat (BAY63-2521) in people with Hypertension, Pulmonary and Ventricular Dysfunction, Left, run by Bayer at 7 sites in 3 countries.

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 1 inclusion and 1 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: stopped early, as of the sponsor's last update on 4 Nov 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in Austria, Czechia, Germany. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study was stopped early (reason given: Recruitment was only stopped after the statistical power of the study was reached and the study objectives could be met despite the premature discontinuation.). Results are not available in the source record.

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?

Pulmonary artery mean pressure at rest (time frame: Peak change from baseline within 6 hours after a single dose of study drug). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01172756, which also lists 1 linked publication.

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 4 Nov 2014.
