Trial summary

Auditory Hallucinations (AH) are experienced by 50 to 70% of subjects with schizophrenia. Almost a quarter of patients are medication resistant to such symptoms. The application of rTMS at low frequency in the left temporoparietal cortex reduces AH. Read more about this study

About this study

Official title: Low and High Frequency Repetitive Transcranial Magnetic Stimulation (rTMS) in the Treatment of Resistant Auditory Hallucination in Schizophrenia: a Double Blind Sham-controlled Randomised Study

Auditory Hallucinations (AH) are experienced by 50 to 70% of subjects with schizophrenia. Almost a quarter of patients are medication resistant to such symptoms. The application of rTMS at low frequency in the left temporoparietal cortex reduces AH. A pilot study reported successful treatment of AH with high frequency rTMS. rTMS (20Hz) should be a shorter and an easier treatment for out-patients with schizophrenia compared to low stimulation treatment.

Read the detailed description

90 schizophrenia patients Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM IV-TR) criteria with persistent Auditory Hallucinations (AH) resistant to antipsychotic treatments will be recruited. A double blind sham-controlled randomized parallel study comparing three groups treated 10 session in 5 days with high frequency (20 Hz), low frequency (1Hz) and sham-controlled condition rTMS. They will be followed 3 month and evaluated using Auditive Hallucination Rating Scale (AHRS), Scale for the Assessment of Positive Symptoms Scores (SAPS), Scale for the Assessment of Negative Symptoms Scores (SANS) and Positive And Negative Symptom Scale (PANSS) global score and Global Assessment of Functioning (GAF) score.

What is being measured

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

  1. To evaluate the efficiency of high frequency (20Hz) repetitive Transcranial Magnetic Stimulation (rTMS) to the left temporoparietal cortex compared to sham controlled condition rTMS in term on Auditory Hallucinations reduction.

    Auditory Hallucinations improvement at 5-day was evaluate with AHRS (Auditory Hallucination Rating Scale) score

    Measured: 5 day

Secondary outcomes (5)
  1. To compare the efficiency of low frequency (1Hz) to sham-controlled condition repetitive Transcranial Magnetic Stimulation (rTMS) in term of Auditory Hallucination reduction.

    Auditory Hallucinations improvement evaluated with Auditory Hallucination Rating Scale (AHRS)

    Measured: 5 days

  2. To compare the efficiency of high frequency to low frequency (1Hz) in term of Auditory Hallucination reduction.

    Auditory Hallucinations improvement evaluated with Auditory Hallucination Rating Scale (AHRS)

    Measured: 5 days

  3. To compare the maintenance of therapeutic effect for one month of high frequency to low frequency (1Hz) in term of Auditory Hallucination reduction.

    Auditory Hallucinations improvement evaluated with Auditory Hallucination Rating Scale (AHRS)

    Measured: 1 month

  4. To evaluate the maintenance of therapeutic effect of high frequency compared to sham controlled condition for 15 days 1 month, 2 months and 3 months

    Measured: 15 days 1 month, 2 months and 3 months

  5. To compare the side effects of each of the active treatment

    Tolerance assessed with the UDVALG of KLINISKE UNDERSOGELSER scale (UKU )

    Measured: at Inclusion and 5 day

Questions about this trial

What is this clinical trial studying?

A study testing high frequency (20Hz) and low frequency (1Hz) in people with Schizophrenia, run by Assistance Publique - Hôpitaux de Paris at 1 site 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 1 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 8 Sep 2023. 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 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.

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?

To evaluate the efficiency of high frequency (20Hz) repetitive Transcranial Magnetic Stimulation (rTMS) to the left temporoparietal cortex compared to sham controlled condition rTMS in term on Auditory Hallucinations reduction. (time frame: 5 day). 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 8 Sep 2023.
