About this study

Official title: Clot Lysis: Evaluating Accelerated Resolution of Intraventricular Hemorrhage (IVH)

The specific objective of this trial is to determine the lowest dose and dose frequency possible with the best pharmacokinetic and safety profile and it's ability to remove a blood clot from the ventricular system.

Read the detailed description

The purpose of this trial is to determine the efficacy and pharmacokinetics of intraventricular injections of multiple low doses of rt-PA. Sixteen subjects were already randomized to receive intraventricular injections of with 0.3 mg or 1.0 mg of rt-PA every 12 hours for up to 8 doses. Results of this stage (n=16) were then analyzed and the most effective dose of 1.0 mg was chosen to be used in the second stage (n=36) to determine the optimal frequency of dosing. We propose to test if this intervention facilitates more rapid clot resolution, complete recovery function and decreased mortality from this condition.

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

  • tissue plasminogen activator, rt-PA (thrombolytic) (Cathflo)Drug

    Also called rt-PA, Cathflo, Activase

    0.3 mg and 1.0 mg of rt-PA (Cathflo) were administered every 12 hours (dose finding) and every 8 hours (dose frequency) via the intraventricular catheter to treat intraventricular hemorrhage.

What is being measured

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

  1. 30-day Mortality

    The number of subjects who died at or before the 30-day follow-up visit were determined as a measure of safety. If more than 50% of the subjects died at or before the 30-day follow-up visit, the study would have been stopped for full DSMB review.

    Measured: 30 days

  2. Incidence of Bacterial Ventriculitis, Meningitis

    The incidence of bacterial ventriculitis/meningitis was recorded to determine the safety of intraventricular administration of rt-PA. If 30% or more subjects experienced this event, the study would have been stopped for full DSMB review.

    Measured: 30 days

  3. Rate of Symptomatic Bleeding Events

    The rate of symptomatic brain bleeding events were recorded to determine the safety of intraventricular administrations of rt-PA. If 35% or more subjects experienced a symptomatic bleeding event prior to the 30-day follow-up visit, the study would have been stopped for a full DSMB review.

    Measured: 30-days

Secondary outcomes (5)
  1. Average Daily Percentage Clot Size Resolution Over the First 3 Days

    Daily IVH clot volume resolution, as a percentage of stability CT IVH volume, averaged over the first 3 days, determined by CT scans

    Measured: 3 days

  2. 90 Day Follow-Up Modified Rankin Scale (mRS) Score

    90 day follow-up visit mRS score. The modified Rankin Scale (mRS) is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. It is scored from 0 to 6: 0. No Symptoms, 1. No Significant Disability, 2. Slight Disability, 3. Moderate Disability, 4. Moderately Severe Disability, 5. Severe Disability and 6. Dead.

    (Stage 1 patients only had 30 day scores, Stage 2 patients had 30 day, 90 day and 180 day scores collected)

    Measured: 90 days

  3. 90 Day Follow-Up Glasgow Outcome Scale (GOS) Score

    90 day follow-up visit GOS score. The GOS is a scale used to determine the degree of recovery from patients with brain injury. There are five categories: 1. Dead, 2. Vegetative State, 3. Severe Disability, 4. Moderate Disability and 5. Good Recovery.

    (Stage 1 patients only had 30 day scores, Stage 2 patients had 30 day, 90 day and 180 day scores collected)

    Measured: 90 days

  4. 180 Day Follow-Up Modified Rankin Scale (mRS) Score

    180 day follow-up visit mRS score. The modified Rankin Scale (mRS) is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. It is scored from 0 to 6: 0. No Symptoms, 1. No Significant Disability, 2. Slight Disability, 3. Moderate Disability, 4. Moderately Severe Disability, 5. Severe Disability and 6. Dead.

    (Stage 1 patients only had 30 day scores, Stage 2 patients had 30 day, 90 day and 180 day scores collected)

    Measured: 180 days

  5. 180 Day Follow-Up Glasgow Outcome Scale (GOS) Score

    180 day follow-up visit GOS score. The GOS is a scale used to determine the degree of recovery from patients with brain injury. There are five categories: 1. Dead, 2. Vegetative State, 3. Severe Disability, 4. Moderate Disability and 5. Good Recovery.

    (Stage 1 patients only had 30 day scores, Stage 2 patients had 30 day, 90 day and 180 day scores collected)

    Measured: 180 days

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 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?

Yes. Results are posted in the registry (first posted 17 Jul 2012). 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?

30-day Mortality (time frame: 30 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 NCT00650858, which also lists 6 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 11 Dec 2017.
