Exclusion criteria: |
1.Prior treatment with regorafenib or any PD-1, PD-L1, or CTLA-4 inhibitor. 2.Receipt of any other antineoplastic therapy (chemotherapy, targeted therapy, immunotherapy, extensive radiotherapy, etc.) within 4 weeks prior to randomization, or persistent toxicity from prior therapy that has not resolved to CTCAE Grade <= 1 (excluding alopecia and similar non-clinically significant toxicities). 3.Symptomatic or uncontrolled central nervous system metastases, including leptomeningeal disease. Patients with treated and stable brain metastases are eligible if asymptomatic for >= 4 weeks, off corticosteroids, and radiographically stable. 4.Pregnant or breastfeeding women. 5.History of seizures or current need for antiepileptic medication. 6.Significant comorbidities affecting the cardiovascular, hepatic, renal, or hematopoietic systems, or any other clinically significant condition that, in the investigator's judgment, makes the patient unsuitable for the study or may interfere with study procedures or results. 7.History of any other malignancy within the past 3 years, except adequately treated basal cell or squamous cell carcinoma of the skin, or carcinoma in situ of the cervix. 8.Concurrent use of warfarin (or alternative anticoagulants such as low-molecular-weight heparin) or any prohibited concomitant medication. 9.New York Heart Association (NYHA) Class III or IV cardiac disease, including congestive heart failure or myocardial infarction within the previous 6 months. 10.Known infection with human immunodeficiency virus (HIV). 11.Major surgery within 2 weeks prior to enrollment. 12.Psychiatric disorders or other conditions that would prevent the patient from complying with the study requirements. 13.Any history, disease evidence, treatment, or laboratory abnormality that may interfere with study results or prevent full participation, or any other condition deemed by the investigator to pose unacceptable risk for study participation. |

随机方法(请说明由何人用什么方法产生随机序列): |
本研究采用中央随机化系统(IWRS/IVRS)实施随机分配。随机化采用预设分层因素的分层随机/分层区组随机算法,由牵头单位数据管理团队或独立统计人员在系统中配置随机参数。研究者在受试者完成知情同意、确认入排标准并录入必要基线信息后,通过中央随机系统获得分组结果;在分配前,参与招募和干预实施的研究者无法访问随机序列,也无法预知下一例受试者分组,从而保证分配隐藏。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Eligible participants will be randomized through a central Interactive Web/Voice Response System (IWRS/IVRS). The system will implement a stratified randomization algorithm based on pre-specified stratification factors. Allocation will be released only after informed consent, eligibility confirmation, and entry of required baseline information. The randomization list and upcoming assignments will not be accessible to enrolling investigators before allocation, thereby ensuring allocation concealment. |

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址): |
不适用。本研究暂不计划公开共享受试者个体层面原始数据(IPD)。研究结果将以论文、会议报告或注册平台结果摘要形式公开。必要时,可在研究完成并发表主要结果后,经牵头单位伦理委员会/数据管理委员会审核,在符合法律法规、伦理批准和受试者隐私保护要求的前提下,提供去标识化的汇总数据或统计分析结果。 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
Not applicable. Individual participant data (IPD) will not be publicly shared. Study results will be disseminated through peer-reviewed publications, conference presentations, or summary results on the registration platform. After completion of the study and publication of the primary results, de-identified aggregate data or statistical analysis outputs may be provided upon reasonable request, subject to approval by the lead institution and compliance with applicable laws, ethics approval, and participant privacy protection requirements. |
|
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: |
本研究数据采集和管理包括病例报告表(Case Record Form, CRF)和电子数据采集系统(Electronic Data Capture, EDC)两部分。各研究中心研究者或授权研究人员根据原始病历、检查报告、影像学评估、不良事件记录和随访记录填写 CRF,并将数据录入 EDC 系统。EDC 系统采用受试者筛选号/随机号进行去标识化管理,设置权限分级、逻辑核查、数据质疑、修改痕迹追踪和审计追踪。牵头中心数据管理人员定期进行数据核查、质疑处理和质量控制,确保数据真实、准确、完整、可追溯。所有研究资料按 GCP 和机构要求保存。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection and management will consist of two components: the Case Record Form (CRF) and the Electronic Data Capture (EDC) system. Investigators or authorized study staff at each site will complete the CRF based on source documents, including medical records, laboratory and imaging reports, tumor assessments, adverse event records, and follow-up records, and will enter the data into the EDC system. Participants will be identified by screening and randomization numbers rather than personal identifiers. The EDC system will include role-based access control, edit checks, data queries, audit trails, and traceable data modifications. The data management team at the lead center will perform regular data review, query resolution, and quality control to ensure that the data are accurate, complete, reliable, and traceable. All study documents will be retained in accordance with GCP and institutional requirements. |
