About this study

The goal of this trial is to evaluate the safety and tolerability of lithium in people with progressive supranuclear palsy or corticobasal degeneration.

Read the detailed description

Progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) are progressive, adult-onset neurodegenerative disorders characterized by the accumulation of hyperphosphorylated tau. Symptomatic treatment is of minimal benefit to individuals with PSP or CBD, and there are no effective disease modifying agents.

Tau phosphorylation is regulated in part by the enzyme GSK-3β (glycogen synthase kinase-3 beta ). Inhibition of this enzyme may benefit individuals with PSP or CBD by decreasing the levels of phosphorylated tau. Lithium is known to inhibit GSK-3β and, thus, may be a rational therapeutic approach.

The primary objective of this study is to determine the safety and tolerability of lithium in people with PSP or CBD. Additionally, this study will evaluate potential biomarkers and clinical outcome measures as well as assess study drug compliance.

In this multicenter, open label study, 45 eligible participants with PSP or CBD will receive the study drug, lithium. The dosage of lithium will be titrated over a 5-week period, and participants will then be followed prospectively for 6 months. Participants will be evaluated at the screening visit, baseline visit, and weeks 2 and 5 during the titration phase. Clinic study visits will then occur on alternate months through week 28. Telephone visits will occur between clinic study visits.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Ability to Tolerate Lithium Carbonate

    The ability to complete the study period on lithium at a serum concentration of at least 0.4 mEq/L.

    Measured: 28 weeks

Secondary outcomes (9)
  1. Study Drug Compliance

    Subjects receiving 80% or more of the prescribed doses between study visits were considered compliant.

    Measured: 28 weeks

  2. Changes in Amount of Tau and Phosphorylated Tau in Cerebral Spinal Fluid (CSF)

    Progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) are characterized by hyperphosphorylation of tau. Lithium inhibits one of the kinases (GSK-3 beta) that phosphorylates tau; levels of tau phosphorylation will be measured at baseline and at Week 28.

    Measured: 28 weeks

  3. Change in Brain-Derived Neurotrophic Factor (BDNF) in CSF

    With inhibition of Glycogen Synthase Kinase (GSK)-3 beta, levels of BDNF may increase. BDNF levels will be measured at baseline and at Week 28.

    Measured: 28 weeks

  4. Change in Glycogen Synthase Kinase (GSK)-3 Beta Activity

    Levels of beta-catenin and the ratio of phosphorylated GSK-3 beta to total GSK-3 beta will be measured at baseline and at Week 28

    Measured: 28 weeks

  5. PSP Rating Scale Score: Change From Baseline

    The PSP Rating Scale is a 28-item scale designed to assess the disability associated with PSP. The six functional categories assessed are: daily activities, behavior, bulbar function, oculomotor function, limb motor function, and gait/midline function. Subjects will be assessed at baseline and Weeks 12, 20, and 28.

    Measured: 28 weeks

  6. Unified Parkinson Disease Rating Scale (UPDRS) Motor Subscale Score: Change From Baseline

    The UPDRS is a commonly used clinical rating scale to assess motor function in patients with parkinsonism. Subjects will be assessed at baseline and Weeks 5, 12, 20, and 28.

    Measured: 28 weeks

  7. PSP-Quality of Life Scale (QoL):Change From Baseline

    The PSP-QoL Scale is an instrument designed to assess mental and physical aspects of quality of life specifically in patients with PSP. Subjects will be assessed at baseline and Weeks 12, 20, and 28.

    Measured: 28 weeks

  8. Frontal Assessment Battery (FAB): Change From Baseline

    The FAB is a brief, 6-item instrument designed to assess executive function. Subjects will be assessed at baseline and at Week 28.

    Measured: 28 weeks

  9. Geriatric Depression Scale(GDS)-15:Change From Baseline

    The GDS-15 is a 15-item instrument used to screen for depression in the elderly. Subjects will be assessed at the Screening Visit and at Week 28.

    Measured: 28 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Lithium in people with Progressive Supranuclear Palsy and Corticobasal Degeneration, run by Westat at 9 sites in 2 countries.

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 19 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 17 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, United Kingdom. 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.

What does this combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 Jun 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Ability to Tolerate Lithium Carbonate (time frame: 28 weeks). 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 17 May 2024.
