A Study To Examine The Distribution Of PF-05212377 In The Brain Of Healthy Volunteer Subjects Using Positron Emission Tomography And A Radioactive Tracer Following Oral Administration Of One Dose Of PF-05212377

April 15, 2014 updated by: Pfizer

A Phase 1, Open-Label Study To Evaluate 5-HT2a Receptor Occupancy As Measured By Positron Emission Tomography (PET) With Ligand [11C]MDL100907 Following Single Oral Dose Administration Of PP-05212377 (SAM-760) In Healthy Subjects

This study will see how PF-05212377, an experimental drug to treat symptoms from Alzheimer's Disease, distributes in the brain after one dose of PF-05212377 is administered orally to healthy volunteer subjects. The study will also evaluate the safety and tolerability of PF-05212377 in these subjects and will measure the level of PF-05212377 in the blood.

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)

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
5-HT2a receptor occupancy of PF-05212377 in the frontal cortex using PET
Time Frame: Days 1 and 2
Days 1 and 2
Plasma PF-05212377 exposure associated with PF-05212377 5-HT2a receptor occupancy
Time Frame: Days 1 and 2
Days 1 and 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
Time Frame
5-HT2a receptor occupancy of PF-05212377 in other cortical regions
