About this study

Official title: Prospective, Multicenter, First Part Randomized, Placebo-controlled, Parallel-group, Double-blind Period Followed by Open-label Trial Period to Evaluate Clinical Safety & Efficacy of NanoLithium® NP03 in Patients With Mild-to-severe Alzheimer's Disease: Proof-of-concept Study

This proof-of-concept study will assess safety, tolerance, and efficacy of NanoLithium® NP03 in patients with mild-to-severe Alzheimer's Disease (AD).

Read the detailed description

This French Study is a prospective, multicenter, randomized (1:1), placebo-controlled, parallel-group, double-blind period followed by an open-label trial period to Evaluate Clinical Safety and Efficacy of NanoLithium® NP03 in Patients With Mild-to-severe Alzheimer's Disease.

Patients will be randomized into two treatment arms:

  • NanoLithium® NP03 (N=34)
  • Placebo (N=34)

The first phase will consist of a double blind 12-week -period, which will be followed by an open-label 36-week period for each arm.

A total of 18 clinical or phone call visits are scheduled during this study. During the follow-up, clinical, biological, electrophysiological, imaging assessments and questionnaires will be performed to determine the safety, efficacy, and disease-modifying effect of NanoLithium® NP03.

Being tested

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing NanoLithium® NP03 in people with Alzheimer's Disease, run by Medesis Pharma SA at 8 sites in France.

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 14 inclusion and 15 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 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in France. 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?

NPI-12 total score (time frame: 12 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 Jan 2025.
