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

- BMI of 17.5 to 30.5 kg/m2 and a total body weight >50 kg (110 lbs)

- Evidence of a personally signed and dated informed consent document indicating that
subject has been informed of all pertinent aspects of the study.

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 the time of dosing)

- Treatment with an investigational drug within 30 days (or as determined by the local
requirement) or 5 half-lives preceding the first dose of study medication (whichever
is longer)

- Subjects with a history of significant active bleeding, coagulation disorder or
clinically significant finding on prothrombin time/ partial thromboplastin
time/International Normalized Ratio (PT/PTT/INR) at Screening

- Subjects with lower spinal malformations (on physical examination), local spinal
infection, or other abnormalities that would exclude puncture (LP)

- Other severe acute or chronic medical or psychiatric condition or laboratory
abnormality that may increase the risk associated with study participation or
investigational product administration or may interfere with the interpretation of
study results and, in the judgment of the investigator, would make the subject
inappropriate for entry into this study

Descriptive Information
Brief Title  ICMJE A Study to Evaluate the Pharmacodynamic Effects of Single Oral Doses of PF-06648671 on ?-Amyloid (A?) Concentrations in Cerebrospinal Fluid (CSF)
Official Title  ICMJE A Phase 1 Investigator-and-subject Blind, Randomized, Placebo Controlled, Parallel Study In Healthy Subjects To Evaluate The Pharmacodynamic Effects Of Single Oral Doses Of Pf-06648671 On A? Concentrations In Cerebrospinal Fluid Using Serial Sampling Methodology
Brief SummaryThis is phase 1 investigator-and-subject blind, sponsor open, randomized, placebo controlled, parallel study in healthy subjects to evaluate the pharmacodynamics effect of single oral doses of PF-06648671 on CSF A? concentrations using serial CSF sampling methodology.
Detailed DescriptionThis study is investigator-and-subject blind, sponsor open, randomized, placebo-controlled, parallel study in healthy subjects to evaluate central (CSF) and peripheral (plasma) pharmacodynamics effects (Abeta) over 36 hours post single doses of PF-06648671. Two cohorts will be run in sequential. the first cohort is to evaluate the Abeta effect at top dose of 300 mg PF-06648671 and second cohort is to evaluate the Abeta effect at top dose (if more subjects are required) and/or 1-2 lower doses
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 1

Condition  ICMJE Healthy Subjects
Intervention  ICMJE
  • Drug: PF-06648671
    Experimental Pfizer compound which will be dosed as oral suspension, single dose at 300 mg and/or 1-2 lower doses
  • Drug: Placebo
    Placebo which will be dosed as oral suspension, single doses to match PF-06648671
Study Arms  ICMJE
  • Experimental: PF-06648671 High dose group
    subjects receive a single oral dose of PF-06648671 at 300 mg
    Intervention: Drug: PF-06648671
  • Experimental: PF-06648671 Low dose group
    Subjects receive a single oral dose of PF-06648671 lower than 300 mg dose
    Intervention: Drug: PF-06648671
  • Placebo Comparator: Placebo group
    Subjects receive matching placebo
    Intervention: Drug: Placebo
  • Experimental: PF-06648671 Low dose group (2)
    Optional arm. Subjects receive a single oral dose of PF-06648671 at second lower dose if 300 mg dose is not repeated in cohort 2
    Intervention: Drug: PF-06648671
