(Tokyo: 4503, “Astellas”) announced today that the company will now make trial data available through, an independent Web site that enables researchers to request and access clinical trial data after approval of a research proposal by an independent review panel.

“Transparency in the conduct of clinical trials is an important issue for the scientific and medical community today,” said Sef Kurstjens, M.D., Ph.D., chief medical officer of Astellas Pharma, Inc. “By making our clinical trial data more widely available, we further its potential to increase understanding of disease and, ultimately, to address the unmet needs of patients around the globe.”

A research proposal will be reviewed and approved by an independent review panel, and Astellas will not be involved in decisions made by the independent review panel.
