Clinical Trial Summary

Clinical Trial Description

This is a registry study of the natural course of unruptured intracranial aneurysms (UIA). In addition, the investigators will analyze the benefit-risk of antithrombotic or anticoagulant therapy in patients with unruptured intracranial aneurysms associated with ischemic heart disease or ischemic cerebrovascular disease. The investigators aim to use research data to create a China national database of UIA. This study is supported by a research grant from the Ministry of Science and Technology of the People's Republic of China. The investigators will collaborate with the other 19 medical centers which locate in the different districts of China.

During the study period, all the patients included in this study will observe and treat in the collaborating medical centers. Included patients will be followed-up for at least 1year. Research data will represent the real natural course of UIA in China. For this study, the investigators consulted and hired professional experts about data collection, data and methodology. An intact systematic project steering committee, including Data Monitoring Committee, Data Management Committee, Project Academic Committee, Executive Group, Project Manager, Project Statistician, and Technical Support Center has been built up. Scientific regulations have also been made ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
