Trial summary

Primary Progressive Aphasia (PPA) is an untreatable neurodegenerative disorder that disrupts language functions. Available therapies are mainly symptomatic and recently attention has been gained by new techniques that allow for noninvasive brain stimulation such as transcranial direct current stimulation (tDCS).

About this study

Official title: The Effects of a Multimodal Approach for the Treatment of Primary Progressive Aphasia

Primary Progressive Aphasia (PPA) is an untreatable neurodegenerative disorder that disrupts language functions. Available therapies are mainly symptomatic and recently attention has been gained by new techniques that allow for noninvasive brain stimulation such as transcranial direct current stimulation (tDCS). The primary objective of this study is to evaluate whether the application of Active tDCS (anode over the left dorsolateral prefrontal cortex- DLPFC with the cathode over the right supraorbital region) to the scalp during individualized language training, would improve naming abilities in the agrammatic variant of PPA (avPPA) more than use of one methodology alone. The effect of treatment on the clinical symptoms will be related to changes in brain activity (Magnetic Resonance Imaging, MRI and Functional near-infrared spectroscopy fNIRS) and in biological markers, using a multimodal approach. Finally, we will assess the long-term effects of this approach.

Read the detailed description

45 patients with avPPA, will be recruited from IRCCS Istituto Centro San Giovanni di Dio Brescia, Italy and ASST Spedali Civili Brescia, Italy .

Inclusion criteria will be a diagnosis avPPA according to the current clinical criteria (Gorno-Tempini et al., 2011) and a FTD Clinical Dementia Rating score >0.5 and <2. Exclusion criteria will be the presence of any medical or psychiatric illness that could interfere in completing assessments and the presence of any medical condition that represents a contraindication to tDCS. All the patients will undergo five consecutive days a week for two weeks of treatment sessions:

15 patients will receive Active tDCS over DLPFC while performing a language training; 15 patients will receive placebo tDCS during language training; 15 patients will receive Active tDCS over DLPFC during unstructured cognitive training.

Two trained neuropsychologists will administer the neuropsychological testing in two sessions. At baseline (T0), post-treatment (T1) and 3-months (T2) follow-up assessments were conducted by the same assessor. Blood sample withdrawal at baseline (T0) and after the DLPFC-tDCS intervention (T1) will be assessed.

To elucidate the mechanisms underlying tDCS effects, structural imaging, functional connectivity (fMRI) alterations and concentration changes of hemoglobin (fNIRS) will be collected off-line. Each avPPA patient will undergo an MRI scan at the ASST Spedali Civili Brescia, Italy at T0 and T1 and a fNIRS acquisition at the IRCCS Istituto Centro San Giovanni di Dio Brescia, Italy at T0, T1 and T2.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Active tDCSDevice

    Active tDCS anode is applied over the left DLPFC with the cathode over the right supraorbital region.

  • Placebo tDCSDevice

    Placebo tDCS is applied but the current is turned off 10 seconds after the beginning and turned on for the last 10 seconds of the stimulation period.

  • Language trainingBehavioural

    patients receive language training

  • Unstructured cognitive trainingBehavioural

    patients receive unstructured cognitive training.

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 2 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 3 Oct 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 Italy. 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?

Change in naming test scores on Picture Naming Task (time frame: Baseline up to 2 weeks and 3 months). 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 3 Oct 2024.
