Compassionate use of drugs and medical devices in the United States, the European Union and Japan

Compassionate use, also called expanded access, provides an important pathway for patients with life-threatening conditions to gain access to unapproved investigational drugs, biologics and medical devices. Although the United States (US) and the countries of the Europe Union (EU) have mechanisms that are associated with the use of unapproved products, as of May 2015 there was no such mechanism in Japan. Instead, unapproved products are used under a physician's discretion in conjunction with the Japan Medical Practitioners' Act or Advanced Medical Care B. However, there are some issues and questions to consider under the current circumstances in Japan as follows: (A) it is difficult for the local regulator to monitor the use of unapproved products; (B) there is no information collected on the safety of these products to protect patients; (C) it is difficult to assure the quality of the products; (D) it is difficult for patients to obtain detailed information about unapproved products and their availability; and (E) it is not clear who should cover the cost of the unapproved products. In this paper, we assess the current compassionate use, or expanded access-related mechanisms, of the US, the EU and Japan in regard to drugs, medical devices and biologics, including human cells and tissue products, and discuss the benefits and issues of these mechanisms. The purpose of these mechanisms is principally to save patients with life-threatening condition. However, the information obtained after the compassionate use is potentially useful to facilitate marketing authorization. In fact, the data from compassionate use cases are employed in some approval review reports to indicate the product safety. (C) 2015, The Japanese Society for Regenerative Medicine.
