[Methods] Literature review and interview survay in US, EU and Japan, concerning science and regulations on MD. [Results and Discussion] The people in US and EU tend to regard that after ICH-M3 the previous related guidance documents on non clinical studies requirements for MD are replaced by ICH-M3, on the other hand, Japanese people don't tend to regard as well, so for them it is not clear whether radiation dose estimation study is required for MD because it is required in the previous guidance but not required in the ICH-M3. [Conclusions] Japanese policy should be made clear whether radiation dose estimation study is required for MD.
