Brief Summary:
The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke or high risk TIA (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke.

Ischemic Stroke Sleep Apnea Sleep Apnea, Obstructive TIA Stroke CPAP Telemedicine Home Sleep Apnea Test Randomized Clinical Trial Multicenter Trial Device: CPAP Not Applicable

Detailed Description:
Sleep SMART has a prospective, randomized, open-label, blinded-endpoint (PROBE) design. It is a multi-site, parallel-group superiority trial that compares 6 months of OSA treatment to usual care. The study includes two trials: a prevention study with an embedded recovery trial. 3062 subjects will be randomized over 5 years at 110 sites within the NINDS-funded StrokeNet clinical trials network.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 3062 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Intervention group receives automatically adjusting continuous positive airway pressure (CPAP) plus usual care.The control group receives usual care.
Masking: Single (Outcomes Assessor)
Masking Description: Eligible participants will be allocated in a 1:1 fashion to CPAP or no CPAP using a randomization method to protect subject treatment allocation and prevent potential selection biases.
Primary Purpose: Prevention
Official Title: Sleep for Stroke Management and Recovery Trial
Actual Study Start Date : May 9, 2019
Estimated Primary Completion Date : November 2026
Estimated Study Completion Date : November 2026

Arm Intervention/treatment
Experimental: Intervention Arm: CPAP with Usual Care.
6 months of CPAP plus usual medical therapy.
Device: CPAP
Automatically-adjusting continuous positive airway pressure (CPAP) delivered using a study supplied device.

No Intervention: Control Arm: Usual Care.
6 months of usual medical therapy alone.

Primary Outcome Measures :
  1. Time to Event Combined Outcome: new ischemic stroke, acute coronary syndrome, or all-cause mortality [ Time Frame: 6 months post randomization ]
    The primary outcome is a time-to-event outcome defined as a participant having at least one of the following events within 6-months from randomization: new ischemic stroke, acute coronary syndrome or all-cause mortality

  2. Modified Rankin Scale Score [ Time Frame: 3 months post randomization ]
    Functional outcome as measured by the 9 question modified Rankin Scale (mRS-9Q). The mRS-9Q has 9 questions related to level of function. Outcomes range from 0 (no symptoms) to 6 (death).

Secondary Outcome Measures :
  1. NIH Stroke Score (NIHSS) [ Time Frame: 3 months post randomization ]
    Neurological outcome is measured by the NIHSS. The NIHSS scale ranges from 0 (no deficits) to 42.

  2. Short Montreal Cognitive Assessment (MoCA) Score [ Time Frame: 3 months post randomization ]
    Cognitive outcome is measured by the Short MoCA. The short MoCA is a 5 minute short version of the Montreal Cognitive Assessment (MoCA). This instrument tests phonemic verbal fluency (1 point), delayed recall (5 points), and orientation (6 points) with a score ranging from 0-12.

  3. Quality of Life outcome [ Time Frame: 3 months post randomization ]
    Quality of life outcome is measured by the shortened Stroke Specific Quality of Life Scale (SS-QOL). The short SS-QOL has 7 domains that include physical function, language, vision, thinking, energy, mood, and role function. There is 1 question from each domain. The 12 item SS-QOL is calculated by averaging the scores of these 12 questions.

Inclusion Criteria:

1. TIA with ABCD2 ≥4 or ischemic stroke, within the prior 14 days.

Exclusion Criteria:

  1. pre-event inability to perform all of own basic ADLs
  2. unable to obtain informed consent from subject or legally authorized representative
  3. incarcerated
  4. known pregnancy
  5. current mechanical ventilation (can enroll later if this resolves) or tracheostomy
  6. current use of positive airway pressure, or use within one month prior to stroke
  7. anatomical or dermatologic anomaly that makes use of CPAP interface unfeasible
  8. severe bullous lung disease
  9. history of prior spontaneous pneumothorax or current pneumothorax
  10. hypotension requiring current treatment with pressors (can enroll later if this resolves)

Individual Participant Data (IPD) Sharing Statement:
Plan to Share IPD: Yes
Plan Description: We will comply with the NIH Data Sharing Policy, Policy on the Dissemination of NIH-Funded Clinical Trial Information, the Clinical Trials Registration and Results Information Submission rule, and StrokeNet SOP on Network Data Sharing Policy. NDMC statisticians will generate data files from each data table and in compliance with HIPAA regulations each table will be de-identified. A minimum number of derived variables necessary to reproduce the primary analysis will be created. Within a year from acceptance of the primary manuscript or no later than two years from database lock, the public-use data sets will be submitted to the NINDS data repository along with final version of the study protocol, data dictionary and a user guide. Data along with signals from sleep apnea recordings will be submitted to the NHLBI National Sleep Research Resource.
