What is being measured

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

  1. Number of Participants With Treatment-emergent Adverse Events (TEAE)

    Analyses of drug-related TEAEs were based on the assessment of causal relationship to study medication.

    Measured: From administration of first dose of study medication in PATENT-2 up to 2 days after end of treatment with study medication, up to 10 years and 5 months.

  2. Number of Participant With Death

    Analyses of deaths were based on the assessment of causal relationship to study medication. The safety follow-up visit was to be performed 30 days after the last dose of riociguat.

    Measured: From baseline to end of safety follow-up visit, up to 10 years and 6 months (1 month more than End of study visit)

Secondary outcomes (4)
  1. Percentage of Participants With Treatment-emergent High Laboratory Abnormalities in Hematology and Coagulation

    Percentage of participants only with a treatment-emergent shift in hematology and coagulation parameters from normal or low at baseline to a high value at a timepoint after the start of treatment. The percentage was calculated by comparing the number of participants with a normal or low value at baseline who had at least one high value after the start of treatment with the number of participants with a normal or low value at baseline who also had at least one valid value after start of treatment.

    A termination visit was only to be performed in the case of premature termination of study medication or if the sponsor announced the official end of the study.

    Measured: From baseline to termination visit, up to 10 years

  2. Percentage of Participants With Treatment-emergent Low Laboratory Abnormalities in Hematology and Coagulation

    Percentage of participants only with a treatment-emergent shift in hematology and coagulation parameters from normal or high at baseline to a low value at a timepoint after the start of treatment. The percentage was calculated by comparing the number of participants with a normal or high value at baseline who had at least one low value after the start of treatment with the number of participants with a normal or high value at baseline who also had at least one valid value after start of treatment.

    A termination visit was only to be performed in the case of premature termination of study medication or if the sponsor announced the official end of the study.

    Measured: From baseline to termination visit, up to 10 years

  3. Percentage of Participants With Treatment-emergent High Laboratory Abnormalities in Clinical Chemistry

    Percentage of participants per treatment group only with a treatment-emergent shift in clinical chemistry parameters from normal or low at baseline to a high value at a timepoint after the start of treatment. The percentage was calculated by comparing the number of participants with a normal or low value at baseline who had at least one high value after the start of treatment with the number of participants with a normal or low value at baseline who also had at least one valid value after start of treatment.

    A termination visit was only to be performed in the case of premature termination of study medication or if the sponsor announced the official end of the study.

    Measured: From baseline to termination visit, up to 10 years

  4. Percentage of Participants With Treatment-emergent Low Laboratory Abnormalities in Clinical Chemistry

    Percentage of participants per treatment group only with a treatment-emergent shift in clinical chemistry parameters from normal or high at baseline to a low value at a timepoint after the start of treatment. The percentage was calculated by comparing the number of participants with a normal or high value at baseline who had at least one low value after the start of treatment with the number of participants with a normal or high value at baseline who also had at least one valid value after start of treatment.

    A termination visit was only to be performed in the case of premature termination of study medication or if the sponsor announced the official end of the study.

    Measured: From baseline to termination visit, up to 10 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Riociguat (BAY63-2521) in people with Hypertension, Pulmonary, run by Bayer at 99 sites in 27 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: finished, as of the sponsor's last update on 7 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 99 sites in Japan, United States, Germany, France, Mexico and 22 more countries. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 22 Oct 2020). 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?

Number of Participants With Treatment-emergent Adverse Events (TEAE) (time frame: From administration of first dose of study medication in PATENT-2 up to 2 days after end of treatment with study medication, up to 10 years and 5 months.). The study lists 2 primary outcomes in all. 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 NCT00863681, which also lists 10 linked publications.

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 7 Nov 2023.
