Study Description
Brief Summary:
The primary purpose of this study is to assess biomarker known as amyloid beta peptide 40 (Ab40) in Cerebrospinal Fluid (CSF), following a single oral dose of PAZ-417 in subjects with Alzheimer Disease (AD). This study will also consider another biomarker amyloid beta peptide 42 (Ab42) in Cerebrospinal Fluid in subjects with Alzheimer Disease and assess the safety, tolerability and pharmacokinetic profile of PAZ-417 in both plasma and Cerebrospinal Fluid in these subjects.

Outcome Measures

Primary Outcome Measures :
  1. This study is the measurement of a biomarker known as amyloid beta peptide 40 (Ab40) in Cerebrospinal Fluid (CSF), following a single oral dose of PAZ-417 in subjects with Alzheimer Disease (AD). [ Time Frame: 6 days ]

Secondary Outcome Measures :
  1. To measure both amyloid beta peptide 42 (Ab42) and PAZ-417 in both plasma and CSF and assess safety using the results of physical examinations, vital sign measurements, ECGs, cardiac telemetry, standard laboratory tests and collection of AES. [ Time Frame: 6 days ]

Ages Eligible for Study:   55 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion:

  1. Men or women of non-childbearing potential, 55 years of age or older with a probable diagnosis of Alzheimer's Disease (AD), according to the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria. Subjects will have AD that is mild to moderate in severity, as qualified by a score of 12 to 26 on the Mini-Mental State Examination (MMSE). Woman of non-childbearing potential must be either surgically sterile (hysterectomy and/or oophorectomy) or postmenopausal at least 1 year and must have a negative serum pregnancy test result within 48 hours before administration of test article. Sexually active men must agree to use a medically acceptable form of contraception during the study and continue it for 12 weeks after test article administration.
  2. Body mass index in the range of 18 to 32 kg/m2 and body weight greater than or equal to 50 kg.
  3. Subjects must be generally healthy, with the exception of AD 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 findings, vital sign measurements, findings on 12 lead electrocardiogram (ECG), or chronic laboratory test results that are associated with stable, well controlled chronic illness.

Exclusion:

  1. Any surgical or medical condition that may interfere with the absorption, distribution, metabolism, or excretion of the test article.
  2. Any significant unstable or uncontrolled cardiovascular, hepatic, renal, respiratory, gastrointestinal, endocrine, immunologic, dermatologic, hematologic, neurologic, or psychiatric disease.
  3. History of vascular disorders (peripheral, coronary, venous), chronic inflammatory disorders (eg, rheumatoid arthritis), hematologic disorders, or bleeding disorders (eg, hemophilia, idiopathic thrombocytopenic purpura, VonWillebrand disease).
  4. History of thrombotic events.
  5. Presence or history of symptomatic vertigo, significant cardiac valvular disease, congestive heart failure, angina pectoris, significant cardiac arrhythmia, or seizures.
