About this study

Official title: A Multicenter, Randomized, Double-blind, Placebo-controlled, 4-arm, 26 Week Parallel-Group Study to Evaluate Efficacy, Safety and Tolerability of 2 Oral Doses and 2 Regimes of Tideglusib vs Placebo in Mild-to-Moderate AD Patients

The main purpose of this study is to evaluate the cognitive changes after administration of tideglusib versus placebo at two oral doses and two treatment regimes for 26 weeks in patients with mild to moderate Alzheimer's disease.

After the 26 week core treatment period, the patients may continue in the study under blinded conditions for an optional extension period up to a maximum of 39 additional weeks (total study duration up to 65 weeks), until the last patient in the study has completed the 26 week of treatment.

Read the detailed description

This double-blind, placebo-controlled, randomized, parallel group study will be conducted at multiple centers in the European Union. Patients with mild to moderate Alzheimer's disease will undergo a screening period, and then they will be randomized to one of these four groups: tideglusib 1000 mg once daily (Q.D.), tideglusib 1000 mg every other day (Q.O.D.), tideglusib 500 mg Q.D., or matching placebo, for a 26-week, double-blind, placebo-controlled treatment period.

What is being measured

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

  1. ADAS-Cog+

    Measured: 26 weeks

Secondary outcomes (11)
  1. Adverse events (AEs): Number of AEs and patients with an incidence rate of ≥ 5% AEs

    Measured: 26 weeks

  2. Change from Baseline of the 3 active study medication groups will be compared with the placebo group in the Alzheimer's Disease Cooperative Study Unit Activities of Daily Living (ADCS-ADL).

    Measured: 26 weeks

  3. Change from Baseline of the 3 active study medication groups will be compared with the placebo group in the Mini Mental State Examination (MMSE)

    Measured: 26 weeks

  4. Change from Baseline of the 3 active study medication groups will be compared with the placebo group in the Word Fluency test

    Measured: 26 weeks

  5. Change from Baseline of the 3 active study medication groups will be compared with the placebo group in the Neuropsychiatric Inventory (NPI)

    Measured: 26 weeks

  6. Change from Baseline of the 3 active study medication groups will be compared with the placebo group in the Geriatric Depression Scale (GDS)

    Measured: 26 weeks

  7. Change from Baseline of the 3 active study medication groups will be compared with the placebo group in the Clinical Global Impression of Change (CGIC)

    Measured: 26 weeks

  8. Change from Baseline of the 3 active study medication groups will be compared with the placebo group in the European Quality of life Instrument (EQ-5D)

    Measured: 26 weeks

  9. Change from Baseline of the 3 active study medication groups will be compared with the placebo group in the Caregiver time (RUD Lite)

    Measured: 26 weeks

  10. Change from Baseline of the 3 active study medication groups will be compared with the placebo group in the Questionnaire on urinary incontinence

    Measured: 26 weeks

  11. Exploratory Endpoints (only in a subgroup of patients at predefined sites): Change from Baseline of the 3 active study medication groups will be compared with the placebo group in levels of τ, phospho-τ, and β-amyloid in CSF and change in MRI measures.

    Measured: 26 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing tideglusib in people with Alzheimer's Disease, run by Noscira SA at 6 sites in 6 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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 2 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Belgium, Finland, France, Germany, Spain and 1 more country. 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 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?

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?

ADAS-Cog+ (time frame: 26 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 2 Oct 2012.
