We examined conditional approval and all-case surveillance designations for new molecular entities investigated between 2000 and 2014 in Japan. Using univariate or multivariate logistic-regression analysis, this study attempted to clarify profiles that affect the receipt of these designations, and to provide guidance for effectively using conditional approval and all-case surveillance designations. Analysis showed that the highest number of drugs to which these systems were applied was category L (“Antineoplastic and immunomodulating agents”) of the Anatomical Therapeutic Chemical Classification System. Orphan drug designation (ODD) and L drugs were significantly correlated with the receipt of both conditional approval and all-case surveillance. These designations shortened the review time. Positive factors that shortened the period of review included ODD, using global data, and joining a global study. Bridging strategy was the only negative factor. Utilization of this Japan-specific PMS system can shorten drug lag, thereby securing the safety of Japanese subjects.
