Inclusion criteria
The factors, or reasons, that allow a person to participate in a clinical study.
Show details

- Healthy male and/or female subjects of non-childbearing potential between the ages of
18 and 55 years

- Female subjects of non childbearing potential that meet at least one of the following
criteria: Achieved postmenopausal status, defined as: cessation of regular menses for
at least 12 consecutive months with no alternative pathological or physiological
cause; and have a serum follicle stimulating hormone (FSH) level confirming the
postmenopausal status; Have undergone a documented hysterectomy and/or bilateral
oophorectomy; Have medically confirmed ovarian failure.

Exclusion criteria
The factors, or reasons, that prevent a person from participating in a clinical study.
Show details

- 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).

- Any condition possibly affecting drug absorption.

- Subjects with epilepsy, or history of epilepsy, or conditions that lower seizure
threshold, seizures of any etiology (including substance or drug withdrawal), or who
have increased risk of seizures as evidenced by history of EEG with epileptiform
activity. Subjects with a history of childhood seizures, and history of head trauma
with loss of consciousness requiring hospitalization overnight will be excluded as
well.

A Phase I Trial to Investigate the Safety and Tolerability of PF-06649751
A Phase 1, Double Blind, Sponsor Open, Randomized, Placebo Controlled, Crossover, Single Oral Dose Escalation Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of PF-06649751 in Healthy Subjects
This study will determine the safety and tolerability of PF-06649751 given orally to healthy volunteers. To determine the optimal dose for future studies, the concentration of the drug over time will be determined by periodic blood samples. The rate of eye blinks will be measured as an indicator of PF-06649751 action on the receptors of interest in the brain.

Primary Purpose: Basic Science

  • Drug: PF-06649751
    Single doses, given by oral solution, starting at 0.25 mg up to a possible maximum of 7.5 mg. The subject will have been fasted for 10 hours prior to the single dose. For each dosing period, 3 subjects will be given a placebo as a comparator. One dose will be given in the fed state.
  • Drug: PF-06649751
    It is believed that the maximum tolerated dose of this compound the eye blink rate (EBR) will also increase. This arm will use EBR measurement technology to verify this hypothesis. In each dosing period, 5 subjects will be given a placebo as a comparator.
  • Experimental: Single ascending doses
    Intervention: Drug: PF-06649751
  • Experimental: Measurement of eye blink rate
    Intervention: Drug: PF-06649751
