About this study

Official title: Bilateral rTMS Clinical Trial for Persistent Auditory Hallucinations Results for a Terminated Study

The primary purpose of this study was to conduct fMRI neuroimaging studies prior to and subsequent to the rTMS intervention. The intent was to ascertain changes in regional brain activation and connectivity that most robustly predict level of improvement in auditory hallucinations elicited by bilateral rTMS as assessed by the primary outcome variables.

Read the detailed description

This study is an extension of previous clinical trials (NCT00308997 and NCT00567281) that were initiated in 2006. This study record provides the results for the amended study NCT00567281 (originally called a 'third arm') that was discontinued following the passing of Dr. Ralph Hoffman. The primary purpose of the study was to conduct fMRI neuroimaging studies prior to and subsequent to the rTMS intervention. The intent was to ascertain changes in regional brain activation and connectivity that most robustly predict level of improvement in auditory hallucinations elicited by bilateral rTMS as assessed by our primary outcome variables. It was hoped that this combined fMRI/rTMS study would provide critical new insights into the neurobiological basis of auditory hallucinations.

The results presented are what was summarized following Dr. Hoffman's passing and were compiled by Dr. Philip Corlett.

What participants receive

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

  • Magstim Rapid 2 system triggering Magstim Super Rapid systemDevice

    Week 1 treatment includes rTMS for 5 sessions to both the left and right Wernicke's area (BA22) synchronous with rTMS to opposite hemisphere middle temporal cortex (BA21). Week 2 treatment includes rTMS given for 5 sessions with positions reversed (e.g., if Wernicke's stimulation was on the left during Week 1, position of rTMS will switch to the right side during Week 2 and vice-versa). As in Week 1, active rTMS will also be given synchronously to the opposite hemisphere middle temporal cortex. Weeks 3 and 4 include 10 stimulation sessions to the configuration of sites producing greater improvement in comparing results of Week 1 and Week 2. rTMS for each stimulation session will be given at 1-Hertz (once per second) for 16 minutes without interruption.

What is being measured

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

  1. PANSS Composite Positive Symptoms Hallucination Score

    The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of patients with schizophrenia.The PANSS positive symptoms hallucinication score has a range of 1-7. Higher scores indicate more severe positive symptoms in patients with schizophrenia.

    Measured: baseline to 4 weeks

  2. PANSS Composite Negative Symptom Scale

    The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of patients with schizophrenia.The PANSS negative scale has 7 Items, with a minimum score of 7 and a maximum score of 49. Higher scores indicate more severe negative symptoms in patients with schizophrenia.

    Measured: baseline to 4 weeks

  3. PANSS Total Score

    The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of patients with schizophrenia.The PANSS total score has a minimum score of 30 and a maximum score of 210. Higher scores indicate more severe symptoms in patients with schizophrenia.

    Measured: baseline to 4 weeks

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 4 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 30 Oct 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 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 30 Oct 2020). 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?

PANSS Composite Positive Symptoms Hallucination Score (time frame: baseline to 4 weeks). The study lists 3 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 NCT04548622, which also lists 4 linked publications.

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 30 Oct 2020.
