Study Evaluating PAZ-417 in Healthy Young/Elderly

Study Overview
=================
Brief Summary
-----------------
This study is to evaluate the safety and tolerability of single, ascending doses of PAZ-417 in healthy young and healthy elderly subjects. The effect of a high fat meal on the metabolism of PAZ-417 will also be studied, along with blood levels of PAZ-417 . Changes in cognitive function will be assessed.

Eligibility Criteria
-----------------
Inclusion Criteria: Men or women, aged 18 to 50 years inclusive (healthy young subjects) and > 65 years inclusive (elderly subjects) on study day 1. Women of nonchildbearing potential may be included if they are either surgically sterile (hysterectomy and/or oophorectomy) or postmenopausal for ≥1 year (with estradiol ≤25 pg/mL[92 pmol/L] and FSH ≥40 mIU/mL) and must have a negative serum pregnancy test result within 48 hours before administration of test article. Women who are surgically sterile or post-menopausal must provide documentation of the procedure by an operative report or by ultrasound and have a negative serum pregnancy test result within 48 hours before administration of test article. The elderly subjects must be generally healthy, but may be enrolled with a stable, chronic illness, if it is well-controlled, and does not interfere with the primary objective of the study. Subjects may be included with clinically important deviations from normal limits in medical history, physical examination, vital signs, 12-lead ECGs, or clinical laboratory test results which are associated with stable, chronic, well-controlled, medical conditions. The estimated creatinine clearance must be within the age-appropriate normal range. Exclusions Criteria: Presence or history of any disorder that may prevent the successful completion of the study. Any surgical or medical condition that may interfere with the absorption, distribution, metabolism, or excretion of the test article. Exclude subjects with a history of vascular disorders (peripheral, coronary, venous), chronic inflammatory disorders (e.g., rheumatoid arthritis), hematologic disorders, and bleeding disorders (e.g., hemophilia, idiopathic thrombocytopenic purpura, von willebrand's disease).
