October 15, 2009 updated by: Pfizer

A Phase 1, Placebo-Controlled, Crossover Study To Evaluate The Safety, Tolerability And Pharmacokinetics Of PF-04455242 After First-Time Administration Of Single Ascending Doses To Healthy Adult Subjects

The purpose of this first in human (FIH) study is to investigate the safety, tolerability, pharmacokinetics ( how the body handles the drug) and pharmacodynamics (how the drug affects the body) of PF-04455242-01 in healthy adult volunteers.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years to 55 years (Adult)

Accepts Healthy Volunteers

Yes

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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.

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
Safety and tolerability of single doses will include neurological assessment, vital signs and adverse event reporting during inpatient stay.
Time Frame: Daily
Daily
Physical exam
Time Frame: Screening, End of Trial (EOT), and Follow Up (F/U)
Screening, End of Trial (EOT), and Follow Up (F/U)
Clinical safety laboratory results
Time Frame: Screening, Day 0 (D0), D2, F/U
Screening, Day 0 (D0), D2, F/U
12-lead ECGs
Time Frame: Screening, D1, D2, F/U
Screening, D1, D2, F/U
Maximum plasma concentration (Cmax), time to reach maximum concentration (Tmax), area under the concentration-time curve (AUC) and terminal half-life (t1/2) .

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

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.
