What is being measured

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

  1. Change in Peak Power Index at Rest

    The peak power index is a calculated hemodynamic parameter. It is derived from the directly measured parameters mean systolic arterial pressure (SAPmean) and mean pulmonary capillary wedge pressure (PCWPmean). These 2 parameters are acquired during a right heart catheterization. The peak power index is calculated from the maximal power (which also takes the calculated parameter cardiac output into account) divided by the left ventricular end-diastolic volume (LVEDV). Formula: Peak Power Index = (SAPmean - PCWPmean)*CO [cardiac output]*16.667/LVEDV

    Measured: Before and 1 hour after administration of study drug

Secondary outcomes (10)
  1. Change in Left Ventricular Stroke Work Index (LVSWI) at Rest

    The left ventricular stroke work index (LVSWI) is a calculated hemodynamic parameter. It is derived from the directly measured parameters mean systolic arterial pressure (SAPmean) and mean pulmonary capillary wedge pressure (PCWPmean). These 2 parameters are acquired during a right heart catheterization. The LVSWI is also dependent of the calculated hemodynamic parameter stroke volume index (SVI). Formula: LVSWI = (SAPmean - PCWPmean)*SVI*0.0136

    Measured: Before and 1 hour after administration of study drug

  2. Change in Left Ventricular Ejection Fraction (LVEF) at Rest

    The left ventricular ejection fraction work index (LVEF) is a calculated echocardiography parameter. LVEF is derived from the directly measured parameters left ventricular end-diastolic volume (LVEDV) and left ventricular end-systolic volume (LVESV). These 2 parameters are acquired during a non-invasive echocardiography examination. Formula: LEVF = 100*(LVEDV - LVESV)/LVEDV

    Measured: Before and 1 hour after administration of study drug

  3. Change in End-systolic Elastance at Rest

    The end-systolic elastance is a calculated hemodynamic parameter. It is approximated by the directly measured hemodynamic parameter end-systolic pressure divided by the directly measured echocardiography parameter left ventricular end-systolic volume (LVESV). The end-systolic pressure is acquired during a right heart catheterization. The LVESV is acquired during a non-invasive echocardiography examination. Approximated by end-systolic pressure/LVESV

    Measured: Before and 1 hour after administration of study drug

  4. Change in Peak Power Index During the Cardiopulmonary Exercise Tests

    The peak power index is a calculated hemodynamic parameter. It is derived from the directly measured parameters mean systolic arterial pressure (SAPmean) and mean pulmonary capillary wedge pressure (PCWPmean). These 2 parameters are acquired during a right heart catheterization. Formula: Peak Power Index = (SAPmean - PCWPmean)*CO*16.667/LVEDV

    Measured: Before and 1 hour after administration of study drug

  5. Change in Lateral Mitral Annular Peak Systolic Velocity (Sm) During the Cardiopulmonary Exercise Tests

    The lateral mitral annular peak systolic velocity (Sm) is a measured echocardiography parameter. It is acquired during a non-invasive echocardiography examination.

    Measured: Before and 1 hour after administration of study drug

  6. Change in Peak Systolic Tricuspid Annular Velocity (RV-Sm) During the Cardiopulmonary Exercise Tests

    The peak systolic tricuspid annular velocity (RV-Sm) is a measured echocardiography parameter. It is acquired during a non-invasive echocardiography examination.

    Measured: Before and 1 hour after administration of study drug

  7. Change in Tricuspid Annular Plane Systolic Excursion (TAPSE) During the Cardiopulmonary Exercise Tests

    The tricuspid annular plane systolic excursion (TAPSE) is a measured echocardiography parameter. It is acquired during a non-invasive echocardiography examination.

    Measured: Before and 1 hour after administration of study drug

  8. Change in Lateral Mitral Annular Peak Early Diastolic Velocity (E') During the Cardiopulmonary Exercise Tests

    The lateral mitral annular peak early diastolic velocity (E') is a measured echocardiography parameter. It is acquired during a non-invasive echocardiography examination.

    Measured: Before and 1 hour after administration of study drug

  9. Change in the Slope of the Relationship Between Work Rate and Mean Pulmonary Arterial Pressure (PAPmean) During the Cardiopulmonary Exercise Tests

    The slope of the relationship between work rate during cardiopulmonary exercise tests and PAPmean is derived from the directly measured hemodynamic parameter mean pulmonary arterial pressure (PAPmean). PAPmean is acquired during a right heart catheterization.

    Measured: Before and 1 hour after administration of study drug

  10. Change in the Ventilatory Efficiency (V'E/V'CO2) Measured From Baseline to the Anaerobic Threshold (AT) During the Cardiopulmonary Exercise Tests (CPET)

    Ventilatory efficiency (V'E/V'CO2) and anaerobic threshold (AT) were parameters directly measured or derived by computed analysis from the spiroergometry system during the cardiopulmonary exercise test.

    Measured: Before and 1 hour after administration of study drug

Questions about this trial

What is this clinical trial studying?

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

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 6 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

Yes. Results are posted in the registry (first posted 6 Jan 2014). 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?

Change in Peak Power Index at Rest (time frame: Before and 1 hour after administration of study drug). 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 6 Jan 2014.
