Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Healthy subjects. (Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12-lead ECG and clinical laboratory tests).

Exclusion criteria

  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
  • A positive urine drug screen.
  • Treatment with an investigational drug within 30 days (or as determined by the local requirement, whichever is longer) or 5 half-lives preceding the first dose of study medication.

Treatment and study plan

PF-03654764

Drug

5mg orally once daily for 10 days. After satisfactory review of the available safety, toleration and PK data, progression to the next dose will occur if the last dose was well tolerated. If the previous dose was not well tolerated, after review of the safety data, and discussion between the Pfizer Study Team and the Investigator, the same dose may be given again, a lower dose within the tolerated dose range may be given, or the study may be stopped. The dose increments will be based on emerging safety and toleration data, as well as plasma exposure estimates and forward predictions of PK. Nominal administered doses will not exceed 24 mg per day.

Placebo

Drug

orally once daily for 10 days. After satisfactory review of the available safety, toleration and PK data, progression to the next dose will occur if the last dose was well tolerated. If the previous dose was not well tolerated, after review of the safety data, and discussion between the Pfizer Study Team and the Investigator, the same dose may be given again, a lower dose within the tolerated dose range may be given, or the study may be stopped. The dose increments will be based on emerging safety and toleration data, as well as plasma exposure estimates and forward predictions of PK. Nominal administered doses will not exceed 24 mg per day.

Primary outcomes

  1. safety & toleration: Adverse events, vital signs, 12 lead ECG, blood and urine safety tests, suicidality assessment using the Suicidality Tracking Scale (STS) and physical examination.

    Time frame: 10 days

Secondary outcomes

  1. Plasma pharmacokinetics: Cmax, Tmax, AUCtau, t½, AUCtau (Day 10)/AUCtau (Day 1), CL/F

    Time frame: 10 days

  2. Urine pharmacokinetics: Ae24 & Ae24% (for once daily doses) or Ae12 & Ae12% (for twice daily dose) on Day 10, CLR

    Time frame: 10 days
