About this study
Official title: Shuxuening Injection for the Prevention of Cerebral Vasospasm in Patients With Aneurysmal Subarachnoid Hemorrhage -- A Randomized, Double-blind, Placebo-parallel Controlled Clinical Trial
Aneurysmal subarachnoid hemorrhage (SAH) is a frequent worldwide cause for stroke with a mortality of around 30%. Worldwide, almost 500 000 patients have aneurysmal SAH annually.An incidence of 2-16 cases of spontaneous SAH per 100 000 person-years was reported in a recent meta-analysis .
Surgical treatment of aneurysms is essential in the acute phase of aSAH patients, either by surgical clipping or by endovascular embolization. Although there are many factors that influence the prognosis of patients with aSAH, cerebral vasospasm (CVS) and delayed cerebral ischemia (DCI) are the main factors contributing to the high mortality rate (30-40% within 30 days) and poor long-term functional prognosis of patients after aSAH. Cerebral vasospasm (CVS) is defined as focal or diffuse temporary narrowing of vessel diameter due to contraction of smooth muscle in the arterial wall, which can be detected by digital subtraction angiography (DSA), transcranial ultrasound Doppler (TCD), magnetic resonance (MR), and CT angiography (CTA) or visualised during intraoperative.The prevalence of CVS after aSAH is 67% , with symptomatic patients (symptomatic vasospasm) in 30-40% of them and leading to ischaemic events in 10-45% of patients. It usually begins 3-4 days after bleeding, peaks at 7-10 days and finally resolves at around 14-21 days.
There is no effective treatment to prevent cerebral vasospasm events.Shuxuening Injection is a sterilized aqueous solution made by extraction of Ginkgo biloba. The study aims to clarify the clinical study of the efficacy and safety of Shuxuening Injection (10ml/branch) for the prophylactic of cerebral vasospasm (CVS) after aneurysmal subarachnoid hemorrhage.
Read the detailed description
This was a randomized, double-blind, placebo-parallel controlled clinical trial.
Patients were randomly divided into 2 groups according to 1:1. Group1: Shuxuening injection treatment group (N1=25): Shuxuening injection (specification: 10ml/branch, Lonch Group Wanrong Pharmaceutical Co., Ltd.), 20 ml (2 branches) + 5% dextrose injection 250 ml, intravenously, once a day, from the first day of postoperative, treatment for 1 course of treatment, a total of 10-14 days; Group2: Placebo control group (N2=25): Shuxuening injection simulant (0.9% sodium chloride injection, specification: 10ml/cartridge, Kunming Yusi Pharmaceutical Co., Ltd.), 20 ml (2 cartridges) + 5% dextrose injection 250 ml, intravenously once a day, from the first day of postoperative, treatment for 1 course of treatment, for a total of 10-14 days; both groups received the basal treatment.
Basic treatment included nimodipine (oral nimodipine, 60 mg, 4 hours/dose), oxygen inhalation,blood pressure and cardiac monitoring, fluid balance and blood glucose management, etc., in accordance with the "2023 American Heart Association/American Stroke Association (AHA/ASA) Guidelines for the Management of Patients with Aneurysmal Subarachnoid Haemorrhage". Patients will be classified according to the Hunt-Hess grade, with H-H I-II grade placed in the general ward and III-V grade placed in the intensive care unit(ICU).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Aneurysmal subarachnoid hemorrhage (SAH) is a frequent worldwide cause for stroke with a mortality of around 30%. Worldwide, almost 500 000 patients have aneurysmal SAH annually.An incidence of 2-16 cases of spontaneous SAH per 100 000 person-years was reported in a recent meta-analysis .
Surgical treatment of aneurysms is essential in the acute phase of aSAH patients, either by surgical clipping or by endovascular embolization. Although there are many factors that influence the prognosis of patients with aSAH, cerebral vasospasm (CVS) and delayed cerebral ischemia (DCI) are the main factors contributing to the high mortality rate (30-40% within 30 days) and poor long-term functional prognosis of patients after aSAH. Cerebral vasospasm (CVS) is defined as focal or diffuse temporary narrowing of vessel diameter due to contraction of smooth muscle in the arterial wall, which can be detected by digital subtraction angiography (DSA), transcranial ultrasound Doppler (TCD), magnetic resonance (MR), and CT angiography (CTA) or visualised during intraoperative.The prevalence of CVS after aSAH is 67% , with symptomatic patients (symptomatic vasospasm) in 30-40% of them and leading to ischaemic events in 10-45% of patients. It usually begins 3-4 days after bleeding, peaks at 7-10 days and finally resolves at around 14-21 days.
There is no effective treatment to prevent cerebral vasospasm events.Shuxuening Injection is a sterilized aqueous solution made by extraction of Ginkgo biloba. The study aims to clarify the clinical study of the efficacy and safety of Shuxuening Injection (10ml/branch) for the prophylactic of cerebral vasospasm (CVS) after aneurysmal subarachnoid hemorrhage.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study of Subarachnoid Hemorrhage, Aneurysmal, run by Xiaolin Chen, MD at 1 site in China.
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 11 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 1 Apr 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 China. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined 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.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 Jun Yang, doctoral (010-18911127316, yangjun4780@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants with cerebral vasospasm(CVS) (time frame: Cerebral vasospasm events within 14 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
