You will be randomized, that is, given a 1 in 4 chance of receiving either 150mg/day of DIO-902, 300mg/day of DIO-902, 450mg/day of DIO-902 or DIO-902 placebo and a 1 in 2 chance of receiving 10mg/day of atorvastatin or atorvastatin placebo. The study drug is a tablet and will be taken by mouth with water. You will take 3 tablets of DIO-902 or DIO-902 placebo and 1 tablet of atorvastatin or atorvastatin placebo each day. The tablets will be taken at the same time each day (2200h or 10:00pm). Neither you nor your doctor will know which dose of DIO-902 or DIO-902 placebo you are on or whether you are taking the atorvastatin or atorvastatin placebo. If necessary, your doctor has a way of finding out which dose you were assigned.
