Propranolol on Post Stroke Immune Status and Infection
China45 participantsStarted 2022-06
Plain-language summary
Stroke-associated pneumonia (SAP) is one of the important risk factors influencing poor outcomes and death in stroke patients. Over the past two decades, accumulating evidence suggests that post-stroke brain injury mobilizes the adrenergic system, which induces post-stroke immunosuppression and SAP. This study is designed to test the safety and efficacy of an adrenergic β-receptor blocker, propranolol, with or without combination of antibiotics, in reducing SAP in stroke patients. The underlying immune mechanisms will be investigated.

. Clinical signs consistent with the diagnosis of stroke, including impairment of language, motor function, cognition, and/or gaze, vision, or neglect.
. Initial NIHSS score of 11 or greater or Total GCS score (aggregate of verbal, eye, and motor response scores) of 5 or greater and no more than 12 at time of enrollment.
. MRI or CT scan confirmed stroke.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
