Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To test that LY450139, a gamma-secretase inhibitor, will reduce the rate of newly synthesize Amyloid Beta by determining the amount of newly synthesized 13C6 leucine-labeled Amyloid Beta in lumbar cerebrospinal fluid from LY450139 treated subjects compared with placebo treated subjects.
