Before a new drug can be used, it is necessary to conduct tests (clinical trials) with the cooperation of many patients to verify the efficacy and safety of the candidate drug.
Only after the efficacy and safety of a drug candidate have been confirmed and approved by the government (Ministry of Health, Labour and Welfare) can it be used as a medicine.
Clinical trials such as these, conducted using candidate drugs to obtain approval from the government (Ministry of Health, Labour and Welfare), are called "clinical trials."
