About this study

Official title: Sildenafil for Prevention of Cerebral Vasospasm Secondary to Subarachnoid Haemorrhage - Phase II Randomized Clinical Trial

A Randomized Clinical Trial with security and dose testing of Sildenafil Citrate in patients with subarachnoid hemorrhage due to a rupture of a cerebral aneurism for prevention of cerebral vasospasm. The cerebral vasospasm is a decrease in blood flow that occurs when the intracranial vessels lose their capability of self-control of dilations and contractions. Patients with subarachnoid hemorrhage without neurological deficits who underwent endovascular or surgical correction of the aneurysm can participate in this trial. They will be randomized to a daily doses of 75 mg of Sildenafil, 150 mg of Sildenafil or Placebo from the third to the 14th day post bleeding. Today there is no proven clinical treatment for prevention of cerebral vasospasm.

What is being measured

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

  1. New neurological Deficit

    Development of clinical symptoms suggestive of vasospasm, which are: afasia, hemiparesis, disorientation, or worsening of consciousness without hydrocephalus or expanding cloth. To access level of consciousness we will use the Glasgow Coma Scale.

    Measured: From third to 14th day post subarachnoid hemorrhage

Secondary outcomes (5)
  1. Transcranial Ecodoppler

    Signs of vasospasm in in transcranial ecodoppler.

    Measured: From the third to the 14th day after subarachnoid hemorrhage

  2. Mortality

    General mortality (for any causes).

    Measured: From the third to the 14th day before subarachnoid hemorrhage.

  3. Side effects

    Drug side effect: hypotension, visual blurring, nasal congestion, angina pectoris, asthma crisis, AV block, digestive bleeding, and priapism.

    Measured: From the third to the 14th day after subarachnoid hemorrhage.

  4. Time to discharge

    Time to discharge (period of hospital stay).

    Measured: From the third day after subarachnoid hemorrhage to discharge.

  5. Rankin Scale

    Modified Rankin scale at discharge.

    Measured: At discharge from the hospital.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Sildenafil Citrate, 25 mg, 3 times a day. and Sildenafil Citrate 50 mg, 3 times a day in people with Subarachnoid Hemorrhage and Cerebral Vasospasm, run by Hospital de Clinicas de Porto Alegre at 1 site in Brazil.

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 5 inclusion and 9 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: withdrawn, as of the sponsor's last update on 25 Mar 2015. 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 Brazil. 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 withdrawn before enrolling participants, so there are no results.

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?

New neurological Deficit (time frame: From third to 14th day post subarachnoid hemorrhage). 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 Mar 2015.
