Trial summary

Idiopathic Intracranial Hypertension (IIH) is a disease that affects mainly young people, and is associated with headache and loss of vision. The medical and surgical management of IIH is problematic and many patients are not treated effectively. Read more about this study

  • Ages 18 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age > 18 years
  • Established diagnosis of Idiopathic Intracranial Hypertension according to the criteria of the 2004 International Classification of Headache Disorders (Table 3).
  • Visual field loss: One of criteria A, B or C must be fulfilled.
  • Severe visual function loss, defined as grades 4 and 5 on the Humphrey Visual Field Analyzer SITA Standard 24-2 Test grading scale (Table 4) at initial presentation.
  • Moderate visual function loss, defined as grade 3 on the Humphrey Visual Field Analyzer SITA Standard 24-2 Test grading scale (Table 4) at presentation and failure of treatment with acetazolamide (Diamox) given at efficient dose (2g/d or maximum tolerated dose) or Topiramate (Topamax) given at efficient dose (maximum 150mg daily). Failure is defined by the absence of visual function improvement after 1 month of treatment and/or medication intolerance.

  • Magnetic Resonance Venography (MRV) or Computed Tomography Venography (CTV) demonstrating bilateral transverse sinus stenosis or unilateral transverse sinus stenosis with contralateral transverse sinus hypoplasia or atresia. At least one of the stenoses must cause ≥ 50% reduction of the sinus lumen diameter.
  • Signed informed consent obtained from the patient.

About this study

Idiopathic Intracranial Hypertension (IIH) is a disease that affects mainly young people, and is associated with headache and loss of vision. The medical and surgical management of IIH is problematic and many patients are not treated effectively. Some cases of IIH are associated with severe stenosis of the large veins of the brain and various researchers have recently reported significant improvement in patients with IIH after the narrow veins of the brain were treated with a stent. Our project aims to evaluate the safety and long-term efficacy of venous sinus stenting in patients with severe IIH refractory to medical management.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Venous Sinus StentingDevice

    Venous sinus stenting consists of placing a stent into the narrowed veins of the brain.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Venous Sinus Stenting in people with Idiopathic Intracranial Hypertension (IIH), run by Weill Medical College of Cornell University at 1 site 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 8 inclusion and 0 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 3 Aug 2020. 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 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Absence of procedure related and device related complications. (time frame: 24 months). The study lists 3 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 NCT01407809, 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 3 Aug 2020.
