About this study

Official title: Experimental Medicine Study to Evaluate the Kinetics of Cerebrospinal Fluid Biomarkers in Subjects With Alzheimer's Disease and Progressive Supranuclear Palsy Compared to Healthy Subjects Using a Heavy Water Labeling Method

This is an experimental medicine study to evaluate the kinetics of cerebrospinal fluid (CSF) biomarkers in subjects with Alzheimer's disease (AD) or progressive supranuclear palsy (PSP) compared to healthy controls using a heavy water (2H2O) labeling method. This study is exploring the time profile of appearance and disappearance of pulse deuterium-labeled cargo proteins in CSF of subjects with AD and/or PSP, which is different from healthy controls, due to deficits in fast axonal transport.

Read the detailed description

Primary Objective:

To compare the time profile of appearance and disappearance in CSF of pulse deuterium-labeled chromogranin B, sAPPα and β-Trace in AD and PSP subjects compared to healthy controls.

Secondary Objectives:

  • To measure body water enrichment of deuterium in saliva and plasma (2H-enrichment (%))
  • To explore the effect of age on the kinetics of deuterium labeling of CSF biomarkers
  • To assess intra and inter subject variability of deuterium-labeling of chromogranin B, sAPPα and β-Trace

Subjects will undergo screening evaluations to determine eligibility prior to heavy water (2H20) administration. Eligible subjects will be admitted to the clinical facility on Day -1. On Day 1, subjects will ingest small doses of 2H20 during their inpatient stay. They will also drink 2H20 for 7 more days. Subjects will undergo two lumbar punctures (LPs) for CSF samples. Subjects will return to the study site approximately 7 days after the last LP (or early termination) for a follow-up assessment and discharge.

Questions about this trial

What is this clinical trial studying?

An observational study of Alzheimer Disease and Progressive Supranuclear Palsy, run by KineMed at 3 sites 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 30 inclusion and 16 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: finished, as of the sponsor's last update on 24 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Biomarker Measures (time frame: Up to 32 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 24 Oct 2014.
