About this study

Official title: A Single-center, Randomized, Open Label, Parallel Arm, Prospective Study to Evaluate the Impact of Early Ventilation in Stroke Outcomes in Patients With Sleep Apnea After First Ever Stroke

To evaluate the impact of early ventilation in stroke outcomes in patients with sleep apnea and first ever stroke, 1 month after stroke.

Read the detailed description

Single-center, randomized, open label, parallel arm, prospective study in patients with sleep apnea after first-ever stroke.

The study will consist of screening, baseline assessment, interventional period (consisting of a treatment period and follow-up visits), and a follow-up phone call.

Patients will be randomly assigned to ASV (active) or control groups, within 4 days after the PSG II and will start the respective intervention in the same day.

Patients assigned to the active group will receive ventilatory support with ASV (DreamStation BiPAP autoSV®) during diurnal and nocturnal sleep, from study randomization until clinically indicated. Patients assigned to control group will receive best medical treatment for stroke alone, including rehabilitation.

What is being measured

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

  1. Proportion of patients with improvement in neurological parameters (reduction of ≥1 point from the beginning in Rankin scale) 1 month after stroke.

    Measured: 1 month after stroke

Secondary outcomes (8)
  1. Proportion of patients with improvement in neurological parameters (reduction of ≥1 point from the beginning in Rankin scale) at 4 and 6 months after stroke.

    Measured: 4 and 6 months after stroke

  2. Change from baseline in National Institutes of Health Stroke Scale (NIHSS) to measure improvement in neurological parameters at month 1, 4 and 6 after stroke.

    Measured: 1, 4 and 6 months after stroke

  3. Type II full polysomnography (PSG II) within 7 days of stroke symptoms onset in all patients with AHI >5 as assessed by ApneaLink™

    Measured: Within 7 days after admission

  4. Adherence in the Servoventilation group

    % nights of device use; average hours per night of device use

    Measured: After 1, 4 and 6 months

  5. Efficacy in the Servoventilation group

    Apnea-Hypopnea Index

    Measured: After 1, 4 and 6 months

  6. Adverse events monitoring

    All AEs occurring within the period of observation for the clinical study must be fully evaluated, documented, reported (if applicable) and archived.

    Measured: Through study completion, an average of 2 years

  7. Cardiovascular events evaluation at month 1, 4 and 6 months after stroke in randomized patients

    Measured: 1, 4 and 6 months after stroke

  8. Cardiovascular events evaluation 12 months after stroke in all participants.

    Measured: 12 months after stroke

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Adaptive Servoventilation (ASV) therapy and Best medical treatment in people with Stroke and Sleep Apnea, run by Philips Portuguesa S.A. at 1 site in Portugal.

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 6 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: status not confirmed, as of the sponsor's last update on 12 Aug 2024. 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 Portugal. 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 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Sílvia Correia, MD (00351969043466, silviapaiscorreia@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of patients with improvement in neurological parameters (reduction of ≥1 point from the beginning in Rankin scale) 1 month after stroke. (time frame: 1 month after stroke). 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 12 Aug 2024.
