Completed
Pfizer
Phase 1
The purpose of this study is to estimate the bioavailability of PF-04457845 tablets relative
to solution and evaluate the effect of food (fasted vs. high fat meal) on the

Phase 2
Inactivation of the FAAH (Fatty Acid Amide Hydrolase) enzyme has been shown to relieve pain
and inflammation in animal studies. PF-04457845 has been shown to inactivate the FAAH enzyme
in animals and healthy human volunteers. The purpose of this study is to evaluate whether
PF-04457845 can inactivate the FAAH enzyme in patients experiencing pain due to OA and
whether this results in these patients experiencing less pain.
