A Study In Healthy People To Evaluate Safety, Toleration, Pharmacokinetics And Pharmacodynamics Of Multiple Oral Doses Of PF-06743649

January 16, 2015 updated by: Pfizer

A Phase 1 Double Blind (3rd Party Open) Randomized, Placebo Controlled, Dose Escalation Study To Investigate The Safety,Tolerability, Pharmacokinetics And Pharmacodynamics Of Repeat Doses Of Pf-06743649 With Or Without Food In Healthy Adult Subjects

The purpose of this study in healthy people is to evaluate safety, toleration and time course of plasma concentration of multiple oral doses of PF-06743649. The pharmacodynamic activity of PF-06743649 will also be assessed. The effect of food on PK of PF-06743649 will also be investigated.

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.

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.

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.
