    To assess the Montreal Cognitive Assessment (MoCA) scale Maximum score 30 Score greater than 26 is considered normal

    Measured: up to 15 weeks

  9. Changes in apathy in Parkinson desease

    • changes in apathy measured by the Apathy Evaluation Scale (AES). Total score ranges: 18 to 72 Higher scores indicating more apathy

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cannabidiol 100 mg/ml, cannabidiol 300 mg/ml and Cannabidiol 400 mg/ml in people with Parkinson Disease, run by Laboratorio Elea Phoenix S.A. at 1 site in Argentina.

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 5 inclusion and 13 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: looking for participants now, as of the sponsor's last update on 5 Dec 2024. 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 Argentina. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Maria Daniela Di Leo, MD (1144898300, daniela.dileo@elea.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of patients with advers events related to treatment acording to CTCAE v5.0 (time frame: up to 21 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 5 Dec 2024.
