Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Patients 18 years of age or greater meeting the following inclusion criteria adapted from Singhal and colleagues 2 will be included:

  1. presentation consistent with RCVS :
  • acute thunderclap/severe headache and supporting clinical features should prompt increased clinical suspicion (eg., potential medication trigger, recent pregnancy, migraine history)
  • evidence of beading/elevated velocities on imaging (Transcranial Doppler (TCD), angiogram, Computer Tomography Angiogram (CTA), MRA) and
  • reversibility (by 90 days)-will not be required for inclusion but will be retrospectively adjudicated

Participants will be excluded from the study if they are:

  • unable to consent AND no family present to consent, or
  • have presence of aneurysmal, traumatic, or mesencephalic Subarachnoid Hemorrhage (SAH), or
  • have presence of other supported diagnosis (eg., vasculitis- inflammatory lumbar puncture) or
  • are currently pregnant or
  • the use of nimodipine or verapamil is contraindicated for any reason (eg., allergy, breast feeding) or
  • have limited TCD sonographic window
  • stroke or ICH/SAH on presentation will not be a contraindication to inclusion in the trial **

About this study

This is a randomized clinical trial of short-acting nimodipine versus twice daily extended release verapamil to treat patients presenting with Reversible Cerebral Vasoconstriction Syndrome (RCVS).

Read the detailed description

Patients greater than 18 years of age presenting with clinical signs and symptoms consistent with RCVS (see inclusion criteria) will be enrolled. Neuroimaging (CT, Magnetic Resonance (MR), or 4 vessel angiogram) will be obtained along with a baseline transcranial doppler ultrasound (TCD). They will subsequently be randomized to receive nimodipine (every 4 hours) or extended release verapamil (twice daily). Mean cerebral blood flow velocities will be followed for reduction or normalization on daily TCD and medication dosing adjusted appropriately. Patients will be followed 90 days post-discharge at which time they will undergo repeat neuroimaging to confirm resolution of vascular abnormalities and repeat evaluation. To determine effectiveness, the investigators will evaluate both short-term (surrogate) in-hospital outcomes and long-term outcomes. Reduction of TCD velocities and headache severity will serve as our short-term surrogate outcomes; however, need for additional medications, blood pressure, new/recurrent stroke/Intracranial Hemorrhage (ICH) will also be evaluated along with modified Rankin score (mRS) on discharge, length of stay, and discharge disposition. At 90 days, the investigators will also assess headache control along with mRS.. Adverse events and their relation to the treatment arms will be assessed, and adherence to the medications will be evaluated.

What participants receive

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

  • NimodipineDrug

    Participants will be administered nimodipine every 4 hours.

  • Verapamil ERDrug

    Participants will be administered long acting verapamil every 12 hours.

What is being measured

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

  1. Peak TCD velocities

    Peak mean Cerebral Blood Flow velocity (CBFV) in anterior circulation vessels (MCA/Anterior Cerebral Artery (ACA)/Posterior Cerebral Artery (PCA)/internal carotid)

    Measured: daily from admission to discharge (approx 5-7 days)

  2. Duration of elevated TCD velocities

    Duration of elevated velocity (number of days from presentation to normalization/reduction)

    Measured: daily from admission to discharge (approx 5-7 days)

  3. Normalization of TCD velocities

    Normalization/reduction of velocity (yes/no)

    Measured: daily from admission to discharge (approx 5-7 days)

Secondary outcomes (6)
  1. Peak pain score

    Peak pain score- Likert scale evaluating headache: 0-10 points

    Measured: every 8 hours while hospitalized (approx 5-7 days) and at 90 day follow-up

  2. Days to pain resolution

    Number of days to resolution

    Measured: every 8 hours while hospitalized (approx 5-7 days) and at 90 day follow-up

  3. New or recurrent stroke/hemorrhage

    evaluated by neurological examinations and confirmed by imaging

    Measured: daily through hospitalization (approx 5-7 days)

  4. Modified Rankin Scale

    functional outcome scale based on mobility and ability to perform activities of daily living- scale 0-6 points (0-2 considered good outcome)

    Measured: on hospital discharge and at 90 day follow-up

  5. Repeat neuroimaging

    repeat neuroimaging to confirm reversibility of vasculopathy

    Measured: at 90 day follow-up

  6. Medication compliance

    ability to tolerate and adhere to medication

    Measured: daily throughout hospitalization (approx 5-7 days) and at 90 day follow-up

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing TCD- cerebral blood flow velocities, Headache pain score and Neurological examination in people with Reversible Cerebral Vasoconstriction Syndrome, run by Johns Hopkins University 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?

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 18 Sep 2019. 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 phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Peak TCD velocities (time frame: daily from admission to discharge (approx 5-7 days)). 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 NCT03150524, which also lists 2 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 18 Sep 2019.
