About this study

The purpose of this research study is to gain a preliminary understanding of the safety of sirolimus in Sturge-Weber syndrome (SWS) and determine best outcomes to be used to assess the utility of sirolimus for the treatment of cognitive impairments related to Sturge-Weber syndrome.

Read the detailed description

Sirolimus will be administered as an adjunct to all current medications. The impact of sirolimus upon cognitive functioning in Sturge-Weber syndrome is the primary outcome measure. This outcome will be assessed using a panel of testing selected based upon extensive experience in testing cognitive function in adults and children with SWS at the Kennedy Krieger Sturge-Weber Center. Changes in a quantitative EEG before and after the trial, Sturge-Weber syndrome clinical neuroscore, port-wine birthmark score, and the impact of sirolimus upon seizures will be assessed.

What is being measured

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

  1. Change in Cognitive Function as Assessed by the National Institute of Health (NIH) Toolbox Cognitive Battery

    Change over six months in cognitive functioning in Sturge-Weber syndrome is the primary outcome measure. This outcome will be assessed using the NIH Toolbox Cognitive Battery, a panel of testing which includes the following measures:

    • the Flanker Inhibitory Control and Attention Test (executive function and attention)
    • the Dimensional Change Card Sort Test (executive function)
    • Picture Sequence Memory Test (episodic memory)
    • Oral Reasoning Recognition Test and Picture Vocabulary Test (language skills)
    • Pattern Comparison Processing Speed Test (processing speed)
    • List Sorting Working Memory Test (working memory)
    • 9-hole Peg Test (dexterity)
    • Grip Strength Test (grip strength) and
    • Patient-Reported Outcomes Measurement Information System (PROMIS) (self-report emotional functioning).

    These scores are rescaled to T scores (mean = 50, standard deviation (SD) = 10), referenced against the US population. Higher scores indicate better outcome. T scores only were analyzed.

    Measured: Baseline and at 6 months on the study drug

Secondary outcomes (3)
  1. Difference in Mean Power Asymmetry of the Occipital Alpha Frequency Band

    Change in mean laterality score (by qEEG power analysis) was done comparing hemispheres and occipital lobes in the following frequency bands; delta, theta, alpha, beta, as previously described. As post-hoc analysis, baseline and follow-up qEEG of patients with and without stroke-like episodes were compared. Greater asymmetry with decreased power on the affected side is worse. We calculated a mean Laterality Score (LSb) for each band, averaged over 30 epochs and included channel pairs. Laterality Scores less than zero indicate lower power on the side ipsilateral to the port wine birthmark. In subjects who had a bilateral port wine birthmark, the side of maximal involvement was used (or the side of known involvement by MRI findings, where present).

    Measured: Baseline and at 6months on the study drug

  2. Change in Sturge-Weber Syndrome Clinical Neuroscore

    Change in clinical neuroscore over the course of the study were measured. The neuroscore is comprised of frequency of seizures (0-4) , extent of hemiparesis (0-4), assessment of visual field cut (0-2) , and degree of cognitive functioning (0-5) with a minimum total score of 0 and a maximum total score of 15. Higher scores mean worsening of symptoms.

    Measured: Baseline and at 6 months on the study drug

  3. Number of Participants With a Change in Sturge-Weber Syndrome Birthmark Score

    Frontal and profile photograph will be taken under standardized conditions with scoring of the port-wine birthmark for percent of face covered, thickness of birthmark, and darkness of birthmark color.

    Measured: Visits at 2 weeks (baseline) and 28 weeks (study end)

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Sirolimus in people with Sturge-Weber Syndrome, run by Anne Comi, MD 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 14 inclusion and 17 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 1 Nov 2021. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

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 1 Nov 2021). 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 Cognitive Function as Assessed by the National Institute of Health (NIH) Toolbox Cognitive Battery (time frame: Baseline and at 6 months on the 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 1 Nov 2021.
