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

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

65 years to 80 years (Older Adult)

Accepts Healthy Volunteers

No

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 Endpoints include: AEs, vital signs, triplicate ECGs,
Time Frame: Day 0 to Day 28
Day 0 to Day 28
Safety Endpoints include: Cosyntropin Stimulation Test, Clinical Examinations, Slit Lamp Examination, Aldosterone Concentrations
Time Frame: Day 0 to Day 28
Day 0 to Day 28
Safety Endpoints include: safety laboratory endpoints (including a complete blood count and a full chemistry panel, including electrolytes, hepatic transaminases, and urinalysis, with microscopic analysis if dipstick analysis is positive),
Time Frame: Day 0 to Day 28
Day 0 to Day 28
Pharmacokinetic endpoints include: Plasma concentrations of PF 03382792 and its N dealkylated metabolite, PF 03227077, will be measured and used to determine Cmax, Tmax, AUC on Day 1 and Css,max, Tss,max, AUC, Css,min, Css,avg on Days 7 and 14.
Time Frame: Day 0 to Day 28
Day 0 to Day 28
Additional pharmacokinetic endpoints: the accumulation ratio (Rac) will be determined from Day 14 and Day 1 AUC. If data permit, t1/2 and urinary excretion parameters (CLR for the parent and Ae and Ae%) will be calculated.
Time Frame: Day 0 to Day 28
Day 0 to Day 28

Study Major Dates

Study Start (Actual)

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.
November 1, 2010

Primary Completion (Anticipated)

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 (Anticipated)

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.
