Trial summary

Primary progressive aphasia (PPA) is a clinical syndrome characterized by the neurodegeneration of language brain systems. Three main clinical variants are currently recorgnized (nonfluent, semantic, and logopenic PPA). Nowadays, there are no effective treatments for this disorder. Read more about this study

About this study

Primary progressive aphasia (PPA) is a clinical syndrome characterized by the neurodegeneration of language brain systems. Three main clinical variants are currently recorgnized (nonfluent, semantic, and logopenic PPA). Nowadays, there are no effective treatments for this disorder.

Transcranial Magnetic Stimulation (TMS) is a technique based on the principle of electromagnetic induction of an electric field in the brain. It has been used as a non-invasive therapy in different disorders, such as depression, bipolar disorder, Parkinson's disease, and in the rehabilitation of post-stroke aphasia. Recent studies have shown how repetitive TMS improved language characteristics in Alzheimer's disease, and there are initial data in patients with PPA.

This research project investigates the effect of repetitive TMS in patients with PPA. Investigators will perform a personalized TMS treatment for each patient (brain region, type of stimulation/inhibition, etc.), according to the specific characteristics of each patient and with the final aim to generate a computational model.

Questions about this trial

What is this clinical trial studying?

A study testing Transcranial Magnetic Stimulation in people with Primary Progressive Aphasia, run by Hospital San Carlos, Madrid at 1 site in Spain.

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 2 inclusion and 5 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 14 May 2020. 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 Spain. 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?

Changes in spontaneous speech (main primary endpoint) (time frame: 2 months (at baseline and at the end of the treatment)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03580954, which also lists 1 linked publication.

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 14 May 2020.
