  Purpose

The purpose of this study is to evaluate the low density lipoprotein cholesterol (LDL-C) lowering effect of PF-04950615 administered subcutaneously at every two weeks (Q14D) in hypercholesterolemic Japanese subjects whose LDL-C is not controlled by a stable dose of atorvastatin, or who are naïve to a treatment by lipid lowering drug and whose LDL-C is not controlled.

Atorvastatin plus PF-04950615 50 mg subcutaneous administration at every two weeks (Q14D SC) for 16 week
Drug: PF-04950615
Atorvastatin plus PF-04950615 100 mg Q14D SC for 16 week
Drug: PF-04950615

Drug: Placebo
Atorvastatin plus PF-04950615 Placebo Q14D SC for 16 week
Drug: Ezetimibe
Atorvastatin plus Ezetimibe 10 mg oral administration once daily for 16 week (open)
Experimental: Population B
A total of 9 groups in two population. Population B comprises hypercholesterolemic Japanese subjects who are naïve for a treatment by lipid lowering drug and whose fasting LDL-cholesterol is not controlled. A subject who is treatment naïve will be randomized into one out of 4 dose groups.
