Efficacy and Safety of Mirabegron in Intracerebral Hemorrhage
Study Details
Study Description
Brief Summary
Intracerebral hemorrhage (ICH) accounts for 10-15% of all strokes without effective pharmacological treatment. Inflammation following ICH contributes to barrier disruption and peri-hematoma edema, leading to deterioration of neurological function. Preclinical evidence suggests that bone marrow hematopoietic stem and progenitor cells (HSPCs) are swiftly activated after ICH. Thereafter, these HSPCs produce an increased output of anti-inflammatory monocytes as an endogenous protective mechanism. Stimulation of β3 adrenergic receptor using selective agonists promotes the production of anti-inflammatory monocytes in bone marrow, and thereby reduces neuroinflammation, brain edema and neurological deficits. This study is to assess the safety and efficacy of a β3 adrenergic receptor agonist Mirabegron as a potential treatment option in ICH patients.

Outcome Measures
Primary Outcome Measures
- Changes in absolute perihematomal edema volume measured by computed tomography (CT) [7 and 14 days]
Repeated CT images will be obtained at 24-48 hours after diagnosis and on days 7 and 14 with CT at 24-48 hours after diagnosis as the baseline for analysis.
Secondary Outcome Measures
- Changes in absolute hematoma volume measured by CT after ICH [7 and 14 days]
Repeated CT images will be obtained at 24-48 hours after diagnosis and on days 7 and 14 with CT at 24-48 hours after diagnosis as the baseline for analysis.
- Changes in NIHSS scores [7 and 14 days]
The assessment will be based on the National Institutes of Health Stroke Scale (NIHSS) with a score range of 0 (asymptomatic) to 42 (death).
- The rate of functional independence at 90 days [90 days]
Number of participants with functional independence. Modified Rankin scale (mRS) is a scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes neurological disability. Functional Independence: 0 - no symptoms at all 1 - no significant disability despite symptoms; able to carry out all usual duties and activities 2- slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance
- Proportion of adverse drug reactions [14 days]
Adverse events related to mirabegron will be recorded.
- All cause mortality [90 days]
Death induced by any cause

-
Patients with the onset of ICH witnessed and/or last seen healthy no longer than 24 hrs previously.
-
Patients with Glasgow Coma Scale (GCS) no less than 6.
