Welcome to the Otsuka Pharmaceutical Clinical Trial Data Transparency website. The website is the communication platform to share information on Otsuka-sponsored clinical trials with researchers in the medical sciences, and in the future, the public.

Presently, Otsuka registers clinical trial information and result summaries in public websites, publishes clinical study results in medical journals and presents results at scientific conferences. Also, Otsuka will provide open public access to summaries of clinical study reports, which are the synopses of formal documents submitted to regulatory agencies.

In addition, Otsuka commits to give full consideration to do the following:

  • Disclose anonymized patient-level data to medical researchers, click here.
  • Seek to coordinate our efforts with other stakeholders in order to share the summary results with trial participants in a format that is easy to access and interpret.
  • Disclose statistics on the number of proposals to access data submitted by medical researchers to Otsuka, and on the decisions made regarding the proposals.
