研究目的:

预试验:研究者利用前列腺手术定位切除水刀系统(metaFlow系统)联合一次性前列腺手术水动力刀头(metaBlade)和尿道膀胱镜(AquaScope)进行BPH的腺体组织切除,获得学习曲线,得出的数据初步观察安全性。若所有受试者出院前未发生严重器械相关并发症,则可初步证明该产品安全,可进一步进行确证性试验。同时对预试验受试者继续完成90天和180天随访,进一步观察试验医疗器械的安全性和有效性。 确证性试验:利用前列腺手术定位切除水刀系统(metaFlow系统)联合一次性前列腺手术水动力刀头(metaBlade)和尿道膀胱镜(AquaScope),与B-TURP用于BPH的腺体组织切除得出的数据相比,评价metaFlow系统及联合使用配件用于良性前列腺组织切除的有效性及安全性。  

Objectives of Study:

Pilot Trial: The investigators will use the Prostate Surgical Targeted Resection Waterjet System (metaFlow System) in combination with the Disposable Prostatic Surgery Hydrodynamic Handpiece (metaBlade) and the Urethro-Cystoscope (AquaScope) to resect prostatic glandular tissue for BPH. This will establish the learning curve and allow for a preliminary observation of safety based on the resulting data. If no severe device-related complications occur in any subjects prior to discharge, the product may be considered preliminarily safe, and further confirmatory trials may be conducted. Additionally, the pilot trial subjects will continue to be followed up at 90 days and 180 days to further observe the safety and effectiveness of the investigational device. Confirmatory Trial: The Prostate Surgical Targeted Resection Waterjet System (metaFlow System), used in combination with the Disposable Prostatic Surgery Hydrodynamic Handpiece (metaBlade) and the Urethro-Cystoscope (AquaScope), will be evaluated for its safety and effectiveness in the resection of benign prostatic tissue. This evaluation will be conducted by comparing the data obtained from its use with that derived from Bipolar Transurethral Resection of the Prostate (B-TURP) for the resection of glandular tissue in BPH.

随机方法(请说明由何人用什么方法产生随机序列):

预试验为单组设计,不涉及随机。 确证性试验采用浙江太美医疗科技股份有限公司开发的IWRS管理随机化分配。 采用分层区组的随机方法,按临床试验机构分层。用SAS 9.4统计软件编程,给定种子数和区组长度,按2:1比例将受试对象分为试验组和对照组,产生至少165例受试者的随机分组安排,并导入中央随机化系统。

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

The pilot study adopts a single-group design without randomization. The confirmatory trial employs IWRS developed by Zhejiang Tailmed Medical Technology Co., Ltd. to manage random allocation.A stratified block randomization method will be used, stratified by clinical trial site. SAS 9.4 statistical software will be applied to generate the random allocation sequence with a given seed number and block length. Subjects will be randomized into the test group and the control group at a ratio of 2:1. The random allocation schedule for at least 165 subjects will be generated and imported into the central randomization system.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

预试验为单组设计,不涉及盲法。 确证性试验由于试验医疗器械与对照方法使用器械外观不同,无法对手术研究者设盲;同时治疗方法记录在出院记录中,受试者能够获知,无法对受试者设盲,因此采用开放的方法,手术研究者与受试者均知道分配结果。 由于包括主要评价指标在内的有效性评价指标涉及受试者填写主观量表,因此发放、讲解、问询量表的研究者应不知道分配结果,避免发放、讲解、问询量表过程中的信息采集偏倚。

Blinding:

The pilot study adopts a single-group design without blinding. In the confirmatory trial, blinding of the operating investigators is not feasible due to differences in appearance between the investigational medical device and the device used in the control method.Meanwhile, the treatment method is documented in the discharge records, and subjects can be aware of their assigned intervention, so blinding of subjects is also not possible.Therefore, an open-label design is adopted, in which both the operating investigators and the subjects are aware of the allocation result. Since the efficacy endpoints including the primary endpoint involve subjective scales completed by the subjects, the investigators responsible for distributing, explaining, and administering the scales shall be unaware of the allocation result to avoid information collection bias during these processes.

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:

临床试验项目采用电子数据采集系统(EDC)由研究者或授权相应人员进行临床试验数据采集。数据核查包括系统逻辑配置后自动触发的核查、通过SAS程序员编写的核查程序完成的SAS核查、以及数据管理员进行的人工核查。

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

For this clinical trial, an Electronic Data Capture (EDC) system will be used by the investigators or their authorized designees to collect clinical trial data. Data verification will include system-triggered checks based on configured logic, SAS checks performed via validation programs written by SAS programmers, and manual verification conducted by data managers.
