The Evaluation Committee on Unapproved or Off-labeled Drugswith High Medical Needs(the Committee)was launched in 2009 to address the issue of unapproved drugs or off-label uses of drugs that are approved in the other developed countriesbut not in Japan. The Committee evaluateswhether a proposed drug or treatment meetshigh medical needs by reviewing the formal petitions submitted by patient advocacy groups, academic societies, and pharmaceutical companies. Based on the review of the Committee, the Ministry of Health, Labour and Welfare (MHLW)determines the mode of regulatory authorization process. Especially for unapproved use of an approved drug, the MHLW decideswhether the use meetsthe criteria foräbbreviated application of publicly known but unapproved indicationc. If applicable, the marketing authorization holder can submit a dossier for the abbreviated application, which includesexis ting data generated from clinical practice without additional clinical trial data. If the drug doesnot meet the criteria, new data from additional registered clinical trialsare usually required. Asof June 2014, the MHLW gave decisionson the mode of regulatory processfor 174 petitionss ubmitted to the Committee during the first and the second public recruitments for drug development. We reviewed these documents to determine which factors were associated with the decision of abbreviated application. Among 59 petitions received in the second recruitment providing detailed background and reasons necessitating the development, 21 petitions provided the data of domestic investigator-initiated prospective trials. Seventeen of the 21 petitions were determined to be valid for abbreviated application, indicating a strong association with the presence of domestic clinical trial data. On the other hand, regulatory approval in other developed countries, despite being a prerequisite for abbreviated application, was inversely associated with actual designation of the abbreviated application. The clinical data required for designation of the abbreviated application are not aswell controlled asone derived from conventional clinical trial data, and consequently are expected to have a lower evidence level. The abbreviated application strategy should be cautiously employed while the issue of drug lag is being resolved gradually in Japan.
