Abstract
Background
Antiphospholipid syndrome (APS) is closely associated with ischemic stroke. However, optimal treatment for APS-related stroke remains unestablished, as current guidelines are based on outdated studies and expert opinion rather than high-quality clinical trials. Evidence on antiplatelet agents other than aspirin, such as clopidogrel, in APS-related stroke is particularly limited. Given the relatively young age of patients with APS and the burden of warfarin use, verifying its necessity is crucial. This study compares clopidogrel-based antiplatelet therapy and warfarin for secondary prevention in APS-related stroke.
Methods
APS-STROKE is an exploratory, multicenter, prospective, randomized, open, blinded-endpoint clinical trial. Adult patients with definite APS and a history of ischemic stroke or transient ischemic attack (TIA) will be included. Patients with high-risk APS (triple positivity or persistently high titers of anti-cardiolipin or anti-β2-glycoprotein I antibodies), systemic lupus erythematosus, or other major indications for continued antiplatelet or anticoagulant therapy will be excluded. Participants will be randomized 1:1 to receive clopidogrel-based antiplatelet therapy or warfarin. More than 200 patients are planned for inclusion across 32 stroke centers. The primary endpoint is a composite of any death, major adverse cardiovascular events, systemic thromboembolic events, and major bleeding during at least 4 years of follow-up. Secondary endpoints include major adverse cardiovascular events, ischemic stroke, any bleeding, major bleeding, intracranial bleeding, clinically relevant non-major bleeding, any death, and thrombosis-related death.
Conclusion
This study will provide valuable information on the optimal secondary prevention strategy for APS-related stroke.
期刊介绍:
Contemporary Clinical Trials is an international peer reviewed journal that publishes manuscripts pertaining to all aspects of clinical trials, including, but not limited to, design, conduct, analysis, regulation and ethics. Manuscripts submitted should appeal to a readership drawn from disciplines including medicine, biostatistics, epidemiology, computer science, management science, behavioural science, pharmaceutical science, and bioethics. Full-length papers and short communications not exceeding 1,500 words, as well as systemic reviews of clinical trials and methodologies will be published. Perspectives/commentaries on current issues and the impact of clinical trials on the practice of medicine and health policy are also welcome.
