NCT01951144

Brief Summary

The purpose of this study in healthy people is to evaluate safety, toleration and time course of plasma concentration of single oral doses of PF-06372865. The pharmacodynamic activity of PF-06372865 will also be assessed. The effect of food on PK and the PK of PF-06372865 administered as a tablet formulation may also be investigated. Pharmacodynamic interaction between PF-06372865 and lorazepam will be evaluated.

Study Arms (4)

Cohort 1:

EXPERIMENTAL

Single ascending doses of PF-06372865 or placebo to investigate the safety/tolerability PK and PD of PF-06372865.

Drug: PF-06372865 or Placebo

Cohort 2:

EXPERIMENTAL

Single ascending doses of PF-06372865 or placebo to investigate the safety/tolerability PK and PD of PF-06372865.

Drug: PF-06372865 or Placebo

Cohort 3:

EXPERIMENTAL

Single ascending doses of PF-06372865 or placebo to investigate the safety/tolerability PK and PD of PF-06372865.

Drug: PF-06372865 or Placebo

Cohort 4 (optional cohort):

EXPERIMENTAL

Two single doses of PF-06372865 or placebo or lorazepam to further investigate the pharmacodynamics of PF-06372865.

Drug: PF-06372865 or Placebo or Lorazepam

Interventions

PF-06372865 will be administered as an extemporaneously prepared solution for all doses unless the tablet formulation need to be evaluated. Correspondingly, placebo doses will be administered as solution or tablet.
