Efficacy and Safety of Mirabegron in Intracerebral Hemorrhage

Phase 2

Recruiting

• Conditions: Intracerebral Haemorrhage
• Interventions: Drug: Standard treatment+mirabegron; Other: Standard treatment

• Registration Number: NCT05369351
• Lead Sponsor: Tianjin Medical University General Hospital

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.

Detailed Description

This study is to evaluate the efficacy and safety of mirabegron in patients with intracerebral hemorrhage based on standard therapy

Arm && Interventions

Group	Intervention	Description
Standard treatment+mirabegron	Standard treatment+mirabegron	In addition to standard treatment, the first dose of mirabegron 50mg/day will be given within 72 hours of symptom onset and continued until the 7th day after onset.
Standard treatment	Standard treatment	Patients will receive usual care

Primary Outcome Measures

Name	Time	Method
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

Name	Time	Method
All cause mortality	90 days	Death induced by any cause
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).
Changes of immune cells in peripheral blood	14 days	The counts of monocytes subsets and other immune cells in peripheral blood were compared.
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
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.
Proportion of adverse drug reactions	14 days	Adverse events related to mirabegron will be recorded.
