Study List

The list will generally include Phase 2 and Phase 3 studies that were filed by Otsuka on or after January 1, 2014 as a part of regulatory submissions to medicines regulatory agencies in the US, EU, and Japan, and for which the relevant drug and indication(s) subsequently were granted regulatory approval. Otsuka may list clinical studies outside this scope.

Clinical studies will be listed after completion of regulatory reviews and decisions.

  • In cases when Otsuka seeks regulatory approval in both the US and EU, the list contains entries for dedicated studies for these jurisdictions following approval in both jurisdictions.
  • In cases when Otsuka is not seeking approval in both the US and the EU, clinical studies will be added to the list after approval in a single jurisdiction.
  • In cases when Otsuka seeks approval in the US, EU and Japan based on global studies, such studies will be added after approval in the US, EU and Japan.

Also, the list may include clinical studies conducted in Japan and filed with the PMDA in Japan on or after January 1, 2014 when approval only in Japan is sought.

For existing and past clinical studies, patient informed consent forms do not allow further research beyond the relevant medicine and the disease that were studied in the original studies and may not allow third-party data sharing. Therefore, patient-level data can be shared only when the aims of the research request fall within the scope of the original research, and the informed consent allows access to third-parties.
