 Duration: It is recommended that the surgery date is defined prior to starting protocol treatment and then the start date of ODM-201 Day 1 will be derived as minus 14 to 21 days from the scheduled surgery date. Treatment will be taken until the day prior to surgery or when the subject is ordered to stop all oral intake i.e., nil per os npo, which ever occurs first. If for some reason surgery takes place more than 21 days after treatment start, it is acceptable that the subject receives ODM-201 for more than 21 days and up to a maximum of 35 days; subject should continue protocol treatment until the day prior to surgery, or npo is ordered. In these cases it is strongly recommended to have surgery performed as soon as possible after 21 days of treatment are completed.
