In middle of March, 2013 tiny Turritopsis polyps were found on a body of a crab Tiarinia cornigera for the first time from Shirahama, Wakayama Prefecure, Japan. Several zooids were cultured for several months, then many Turritopsis medusae were released from well-developed colonies. Young medusae can rejuvenate to the polyp soon.

The major factors that have heretofore prevented an efficient implementation of clinical trials include deviations from the protocol at the investigator's site, defectiveness in filling out the case report forms (CRFs), frequent monitoring and fixing work of patient data by the sponsor, handwritten preparation of various documents, and so on.<BR>As an experiment in electronic implementation of an efficient clinical trial utilizing information technology, we formed an electronic data capture (EDC) system that efficiently collects clinical data from the investigator's site, and applied it to a clinical trial. As a result, there was no patient with a GCP violation and thus all were eligible as study subjects and the number of correction log form (CLF) for CRFs was considerably reduced. In addition, it was possible to conduct an efficient clinical trial and shorten the study period by utilizing this EDC system. We discuss the future readiness for clinical trials based on this experience of implementation, as well as the challenges that lie ahead.
