研究目的:

1 我们拟进行一项II期多中心、双盲、随机对照试验(RCT),旨在评估在动脉瘤性蛛网膜下腔出血(aSAH)后早期补充牛磺酸是否能够降低患者血液和脑脊液(CSF)中脂质过氧化生物标志物(丙二醛—MDA 和 F2-异前列腺素)以及脑损伤标志物(S100钙结合蛋白B—S100B)的水平,相较于安慰剂组。 2 鉴于肠道微生物组紊乱可能降低血液和脑组织中的牛磺酸水平,进而促进脑动脉瘤的发生与破裂,本试验还将评估牛磺酸补充是否能够相对于安慰剂重新调节aSAH患者的肠道微生物组结构。  

Objectives of Study:

1 We propose a phase II multicentre double-blinded randomised controlled trial (RCT) to evaluate whether early taurine supplementation after aSAH can reduce biomarkers of lipid peroxidation (malondialdehyde – MDA and F2-isoprostanes) and brain injury (S100 calcium-binding protein B - S100B) in the blood and cerebrospinal fluid (CSF) of patients with aSAH, compared to a placebo. 2 Given that disturbances in the gut microbiome may reduce blood and brain taurine levels, potentially leading to the development and rupture of brain aneurysms, this trial will also assess whether taurine supplementation can reprogram the gut microbiome of patients with aSAH compared to a placebo.

药物成份或治疗方案详述:

牛磺酸胶囊由西澳大利亚的Optima Ovest公司生产,外观相同的安慰剂为Coloron公司生产的专有产品StarCap。安慰剂胶囊成分为预胶化玉米淀粉与玉米淀粉的混合物。 临床试验级研究干预药物由注册的药品及医药制造公司提供,并根据随机化与分配编码按顺序编号,每位受试者单独存放于一个密封瓶中。分配的研究干预措施将由研究护士(或负责的研究调查员)给予。每日服用4粒胶囊,口服或溶于10毫升水中,经鼻胃管注入,随后用10毫升水冲洗鼻胃管,持续最多7天。每位患者研究用药瓶中未使用的胶囊将在试验结束后统一销毁。 

Description for medicine or protocol of treatment in detail:

Taurine capsules produced by Optima Ovest, the company from the Western Australia. The identical-looking placebo is a proprietary product from Coloron called StarCap. Placebo capsule is a mixture of pregelatinized maize starch and maize starch. Clinical trial grade study intervention, provided by a registered Pharmaceutical and Medicine Manufacturing company, will be sequentially numbered according to the randomization and allocation codes, in one separate sealed bottle for each study participants. The allocated intervention will be administered by a research nurse (or the attending study investigator). 4 capsules orally or dissolved in 10ml water through a nasogastric tube followed by flushing the nasogastric tube with 10ml of water on a daily basis for up to 7 days. Any unused study capsules within the study intervention bottle for each patients will be discarded.

随机方法(请说明由何人用什么方法产生随机序列):

将采用可变区组大小的置换区组随机化方法,按照1:1的比例将参与者分配至牛磺酸组或安慰剂组。计算机化的随机化及分配隐藏将通过REDCap(研究电子数据采集系统)完成,该系统是一种安全的基于网络的研究数据管理应用程序。

Randomization Procedure (please state who generates the random number sequence and by what method):

A permuted block randomisation method with variable block sizes will be used to allocate participants to either taurine or placebo in a 1:1 ratio. Computerised randomisation and allocation concealment will be performed by REDCap – Research Electronic Data Capture, a secure, web-based research data management application.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

研究用的牛磺酸胶囊和安慰剂胶囊在外观上无法区分,唯一知晓分组隐藏信息的是主要研究者(PI)。如果发生不良事件,该信息可被披露,以便临床医生在患者管理过程中了解胶囊的具体身份。

Blinding:

The study taurine and placebo capsules are indistinguishable in appearance and the only person who is aware of the concealment is the PI and this can be disclosed if adverse events are reported and the clinicians will need to know the identity of the study capsules for their management of the patients.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

所有数据,包括血液、脑脊液(CSF)样本、直肠拭子、参与者的病史、健康状况及临床事件,将由经过培训的工作人员进行收集。血浆和脑脊液样本将被冷冻并储存在-80°C,以便后续使用商业化的ELISA或比色法试剂盒进行分析。直肠拭子样本采集后将立即在-80°C保存,用于在香港中文大学(CUHK)进行宏基因组测序。每日ICU临床数据将从现有的ICU临床信息系统中提取。 所有数据将录入预先设定的电子病例报告表(eCRF),该报告表通过REDCap系统管理,是一个位于香港中文大学服务器上的安全网络平台。仅授权的研究人员可访问数据库。每个研究地点还将单独保存一份纸质筛选记录日志,存放于安全且上锁的办公室内。该日志仅包含筛选日期、病历号码、患者姓名首字母缩写和年龄信息。 入选患者将被分配唯一的研究编号,以在研究数据库中保护其身份信息,所有数据均以患者的研究编号录入病例报告表。所有研究数据将依照《药物临床试验质量管理规范》(Good Clinical Practice, GCP)以及各研究点的保密要求进行管理。所有研究数据将在试验结束后保存超过10年,之后根据当地隐私保护法规进行销毁。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

All data including blood, CSF samples, rectal swab, participants' medical history, medical condition and clinical events will be collected by trained staff. Plasma and CSF samples will be frozen and stored at -80C for subsequent analysis using commercially available ELISA or colorimetric kits. Rectal swab samples will be collected and immediately stored at -80C for metagenomic sequencing at the Chinese University of Hong Kong. Daily ICU clinical data will be capured from existing ICU Clinical Information Systems. All data will be recorded to a prespecified eCRF using REDCap, for which is a secure web-based case report located on the CUHK server. Only names investigators will have access to the database. A paper screening log will also be kept separately at each study site, in a secure, locked office. This log will only contain the date screened, medical record number, patient initials and age. Enrolled patients will be allocated a unique study number to protect their identity within the research database, and all data will be entered into the CRF under the patient's study number. All study data will be managed according to Good Clinical Practice and site confidentiality requirements. All data will be kept for >10 years before being destroyed according to local privacy requirements.
