Learn About our Clinical Trials

Clinical trials are an essential part of the process of developing and delivering new medications. We believe that access to clinical trial data is valuable for the advancement of public health and science. This means sharing clinical trial data responsibly, in a way that safeguards the privacy of patients, respects the integrity of national regulatory systems and maintains incentives for investment in biomedical research. Otsuka registers clinical trial information and result summaries on public websites, publishes clinical study results in medical journals and presents results at scientific conferences. We also provide open public access to summaries of clinical study reports, which are the synopses of formal documents submitted to regulatory agencies. Clinical trial information can be found on http://www.ClinicalTrials.gov and http://www.clinicaltrials.jp. Clinical study report summaries are published on https://clinical-trials.otsuka.com for all studies in patients included in marketing authorization submissions filed with US Food and Drug Administration, the European Medicines Agency and the Pharmaceuticals and Medical Devices Agency (PMDA) in Japan.
