Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Mini Mental State Exam (MMSE) score between 14-26 (inclusive) at screening.
  • Participants must be receiving acetylcholinesterase inhibitors on a stable dose for at least 4 months prior to randomization

Exclusion Criteria:

  • Current evidence or history of neurological, psychiatric and any other illness that could contribute to non-Alzheimer's dementia.
  • Known history of familial AD or any evidence for early onset AD known or possibly associated with genetic mutations.
  • Evidence or history of diabetes mellitus Type 1 or Type 2.
  • History or symptoms of autoimmune disorders.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Evaluate the efficacy of PF 04494700 relative to placebo. Change from baseline in a standardized cognitive measure after 18 months of treatment.
Time Frame: 18 Month
18 Month
Examine the safety and tolerability of PF 04494700 relative to placebo. Adverse events, vital signs, physical exam, neuro exam, 12-lead ECG, lab tests (hematology, blood chemistry, urinalysis) and brain magnetic resonance imaging (MRI).
Time Frame: 18 Month
18 Month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Evaluate the effects of PF 04494700 on potential biomarkers of RAGE inhibition and amyloid imaging (AV-45, F18 PET)
Time Frame: 18 Month
18 Month
Evaluate the potential dose response of PF 04494700
Time Frame: 18 Month
18 Month
Evaluate the pharmacokinetics and characterize the pharmacokinetic (PK)/ pharmacodynamic (PD) relationship of PF 04494700 to potential biomarkers and relevant efficacy and safety endpoints
Time Frame: 18 Month
18 Month

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 1, 2007

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (ACTUAL)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
