Knowing what countries to submit clinical trial results summaries to is the easy part. What becomes difficult is learning the intricacies and transparency requirements of every clinical trial registry globally, including the Clinical Research Information Service (CRiS) in South Korea. Here is an overview of this registry:

Registry name: Clinical Research Information Service (CRiS)

Country: South Korea
Year established: 2010
Points of interest:

  • CRiS is under the direction of the Korea Centers for Disease Control and Prevention (KCDC), receiving funding exclusively from South Korea’s Ministry of Health and Welfare (MOHW).
  • In the first four years of operation, only 17.8 percent of clinical trials were registered before the first subject enrolled in the study.
  • All processes for registering clinical trials in CRiS are in the Korean language, and a mastery of the language is needed to register trials in this system.
  • CRiS recommends registering clinical trials before the first subject’s enrollment, but it does accept clinical trial registration when a study is ongoing or after it has completed.
  • Registration of clinical trials is Korea is not yet legally required (as of January 2019).
