Primary Outcome Measures:
  • Safety and tolerability of single doses will include neurological assessment, vital signs and adverse event reporting during inpatient stay. [ Time Frame: Daily ] [ Designated as safety issue: Yes ]
  • Physical exam [ Time Frame: Screening, End of Trial (EOT), and Follow Up (F/U) ] [ Designated as safety issue: Yes ]
  • Clinical safety laboratory results [ Time Frame: Screening, Day 0 (D0), D2, F/U ] [ Designated as safety issue: Yes ]
  • 12-lead ECGs [ Time Frame: Screening, D1, D2, F/U ] [ Designated as safety issue: Yes ]
  • Maximum plasma concentration (Cmax), time to reach maximum concentration (Tmax), area under the concentration-time curve (AUC) and terminal half-life (t1/2) . [ Time Frame: 0 hr (predose) then 0.5-1 hr for the next 12 hrs postdose on D1, then 24, 36, 48, & 72 hrs postdose ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Likert and Drug Effect Questionnaire (DEQ) questionnaires [ Time Frame: 0 hr (predose) then 1, 2, 3, 4, 6 ,8, & 12 hrs (postdose) on D1, then 24 hrs (postdose) on D2 ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Active Comparator: Treatment
2 cohorts will recieve single rising doses of PF-04455242 or placebo in a cross-over fashion.
Drug: PF-04455242
Powder-in Capsule (EP-PIC), will be used to administer doses from 0.5 mg up to and including 56 mg of a single rising dose over 3 treatment periods receiving two doses of PF-04455242 and one dose of placebo. A one-week (minimum) washout will separate each treatment period.
Placebo Comparator: Placebo
2 cohorts will receive single rising doses of PF-04455242 or placebo in a cross-over fashion.
Drug: Placebo
PIC matching in appearance to PF-04455242 will be used to administer placebo.
