The Clinical Research Information Service (CRIS) is a non-profit online registration system for clinical trials (researches) being conducted in Korea. It can also be accessed via ICTRP. 

As well as the main search options, it is also possible to search by topic (condition, intervention type and phase).

Some completed trials have results within the records.

The database is analysed in this publication:
