Arms	Assigned Interventions
Placebo: Placebo Comparator	Drug: Placebo Subjects receive placebo plus non-pharmacological weight loss program.
CP-945,598: Experimental	Drug: CP-945,598 Subjects receive CP-945,598 plus non-pharmacological weight loss program.
CP-945,598 Treatment B: Experimental Subjects receive CP-945,598 plus non-pharmacological weight loss program.	Drug: CP-945,598 Treatment B Subjects receive CP-945,598 plus non-pharmacological weight loss program.

Detailed Description:

The CP-945,598 program was terminated on November 3, 2008 due to changing regulatory perspectives on the risk/benefit profile of the CB1 class and likely new regulatory requirements for approval. No safety issues were involved in the termination decision.
