Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 60 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • Provide signed and dated informed consent form
  • Male or female, aged 18 to 60
  • Willing to comply with all study procedures and be available for the duration of the study
  • Primary diagnosis of schizophrenia or schizoaffective disorder according to DSM-IV (29)
  • Currently reporting AHs, rated a minimum of 4 (moderate) on the auditory hallucination item of the Brief Psychiatric Rating Scale (BPRS; 27), and AH will be present daily
  • AHs must have failed to resolve after a minimum of two adequate trials (doses within standard therapeutic range for a minimum of 8 weeks each) of psychotropic medication including at least one atypical antipsychotic medication; documented trials of antipsychotic medication limited by intolerable side effects, e. g. extra-pyramidal symptoms, tardive dyskinesia, weight gain, neuroleptic-induced dysphoria, will also be considered as equivalent to adequate trials.

Who cannot join

  • Substance abuse or dependence in the past 1 month
  • Current or past history of serious medical or neurological illness that could compromise brain function or present an increased risk of seizure, e. g. conditions that may significantly alter electrolyte balance, stroke, epilepsy, any history of seizure;
  • Pregnant or trying to become pregnant;
  • Inability to tolerate small, enclosed spaces without anxiety;
  • Metals, implants or metallic substances within or on the body that might cause adverse effects to the subject in a strong magnetic field, or interfere with image acquisition, e. g. aneurysm clips, retained particles, neurostimulators, foil-backed transdermal patches;
  • Facial tattoos with metallic ink
Show all 13Show fewer
  • Inability to follow study protocol
  • Change in antipsychotic therapy in previous 2 weeks
  • Currently under an alternative treatment order
  • Unstable symptoms which could, in the judgment of the study team, exhibit symptomatic worsening over the course of the protocol
  • Current treatment with another investigational drug or other intervention
  • Anything that, in the opinion of the investigator, would place the subject at increased risk or preclude the subject's full compliance with or completion of the study;
  • No quantifiable motor threshold such that TMS dosage cannot be accurately determined

About this study

Official title: Functional Targeting of Transcranial Magnetic Stimulation for the Treatment of Refractory Auditory Hallucinations in Schizophrenia

Repetitive transcranial magnetic stimulation (rTMS) is a new noninvasive therapy that uses magnetic energy applied to the scalp to modulate activity in the underlying regions of the brain. In this study we will examine the efficacy of treating auditory hallucinations in schizophrenia with rTMS, comparing two methods to target stimulation to a language processing region of the brain. One method targets the stimulation site using scalp landmarks, while the other uses functional magnetic resonance imaging (fMRI) combined with a language task.

Conditions
Schizophrenia
Being tested
rTMS with fMRI-based targeting, rTMS with landmark-based targeting

What participants receive

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

  • rTMS with fMRI-based targetingProcedure or surgery

    Inhibitory (low frequency) 1-Hz rTMS will be applied to the secondary auditory cortex during 10 daily 20-minute treatment sessions. An fMRI scan combined with a language task will be used to localize the secondary auditory cortex, followed by neuronavigation to identify the scalp location overlying the targeted cortex.

  • rTMS with landmark-based targetingProcedure or surgery

    Inhibitory (low frequency) 1-Hz rTMS will be applied over the left temporoparietal cortex (TPC) during 10 daily 20-minute treatment sessions, with the stimulating coil located midway between the left temporal (T3) and parietal (P3) scalp landmarks, using the International 10-20 system for EEG.

What is being measured

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

  1. Change in Severity of Auditory Hallucinations

    Hallucination Change Scale (Hoffman RE, Gueorguieva R, Hawkins KA, Varanko M, Boutros NN, Wu YT, et al. (2005): Temporoparietal transcranial magnetic stimulation for auditory hallucinations: safety, efficacy and moderators in a fifty patient sample. Biol Psychiatry. 58:97-104.) Baseline score, by definition: 10 Range: 0 (no hallucinations) to 20 (hallucinations twice as bad as baseline) Thus, a score of less than 10 means that hallucinations were reduced, whereas a score of greater than 10 means that hallucinations were increased.

    Measured: Two weeks

Questions about this trial

What is this clinical trial studying?

A study testing rTMS with fMRI-based targeting and rTMS with landmark-based targeting in people with Schizophrenia, run by University of Michigan at 1 site in United States.

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 7 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: stopped early, as of the sponsor's last update on 8 Dec 2021. 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 United States. 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?

Yes. Results are posted in the registry (first posted 8 Dec 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Severity of Auditory Hallucinations (time frame: Two 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 8 Dec 2021.
