Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 55 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- 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.
- Body mass index in the range of 18 to 32 kg/m2 and body weight greater than or equal to 50 kg.
- 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.
Who cannot join
- Any surgical or medical condition that may interfere with the absorption, distribution, metabolism, or excretion of the test article.
- Any significant unstable or uncontrolled cardiovascular, hepatic, renal, respiratory, gastrointestinal, endocrine, immunologic, dermatologic, hematologic, neurologic, or psychiatric disease.
- 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).
- History of thrombotic events.
- Presence or history of symptomatic vertigo, significant cardiac valvular disease, congestive heart failure, angina pectoris, significant cardiac arrhythmia, or seizures.

About this study
Official title: A Randomized, Single Dose, Placebo-Controlled, 2 Period Crossover Study of the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of PAZ 417 in Cerebrospinal Fluid, When Administered Orally to Subjects With Alzheimer's Disease
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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).

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing PAZ-417 in people with Alzheimer Disease, run by Wyeth is now a wholly owned subsidiary of Pfizer at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 4 Aug 2009. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early. Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Aug 2009.
