Trial Summary

Will I have to stop taking my current medications?

If you are taking antipsychotic medication, you must keep the dose the same for at least 4 weeks before starting the trial. If you are not on antipsychotic medication, you should not start any until the study is over, which is about 2 weeks.

What data supports the effectiveness of the treatment Focused Ultrasound Therapy for Schizophrenia?

Research on similar treatments like repetitive Transcranial Magnetic Stimulation (rTMS) guided by MRI has shown promise in treating auditory hallucinations in schizophrenia, suggesting that imaging-guided therapies can be effective. However, the specific effectiveness of Focused Ultrasound Therapy for schizophrenia is not directly supported by the provided studies.12345

How is the treatment PLIFUS different from other treatments for schizophrenia?

PLIFUS (Low-Intensity Focused Ultrasound) is unique because it uses sound waves to target specific brain areas, potentially offering a non-invasive way to influence brain circuits involved in schizophrenia, unlike traditional medications that often have systemic effects.678910

What is the purpose of this trial?

This trial tests PLIFUS, a sound wave technique, on people with schizophrenia who have ongoing hallucinations or delusions. The goal is to see if targeting a specific brain area can improve their symptoms.

Eligibility Criteria

This trial is for individuals with schizophrenia or schizoaffective disorder who have been experiencing continuous mild or greater hallucinations or delusions for at least 4 weeks. Participants must be stable on their current antipsychotic medication dose, if any, for the past month, and females of childbearing potential must use reliable birth control. People with significant medical conditions, metal implants incompatible with MRI, substance abuse issues (excluding nicotine and THC), major mood disorders other than schizophrenia spectrum disorders, recent suicidal ideation or attempts are excluded.

Inclusion Criteria

I have been experiencing severe symptoms of psychosis for at least 4 weeks.
I am not pregnant, nursing, or planning to become pregnant and will use birth control during the study.
I have been diagnosed with schizophrenia or schizoaffective disorder.

Treatment Details

Interventions

  • MRI
  • PLIFUS
  • Sham PLIFUS
Trial Overview The study tests PLIFUS (Pulsed Low-Intensity Focused Ultrasound) targeting the right Globus Pallidus Interna in people with schizophrenia to see if it affects psychotic symptoms and brain function. Each participant will undergo one session of real PLIFUS and a sham (fake) treatment in random order a week apart. If early results show no benefit after four participants complete the sessions, the protocol may change to three sessions over five days.
Participant Groups
2Treatment groups
Experimental Treatment
Group I: Sham, then Pulsed Low-Intensity Focused Ultrasound (PLIFUS)Experimental Treatment3 Interventions
Participants will receive sham sonication on the first intervention visit, then PLIFUS sonication on the second intervention visit. Visits will be separated by 1 week. Sonication at both visits will be preceded and followed by fMRI and an exit medical examination. Sonication will be delivered in a pulse pattern over 10 minutes.
Group II: Pulsed Low-Intensity Focused Ultrasound (PLIFUS), then ShamExperimental Treatment3 Interventions
Participants will receive PLIFUS sonication on the first intervention visit, then sham sonication on the second intervention visit. Visits will be separated by 1 week. Sonication at both visits will be preceded and followed by fMRI and an exit medical examination. Sonication will be delivered in a pulse pattern over 10 minutes.

Findings from Research

A randomized-controlled trial involving 144 patients with schizophrenia will test the efficacy of high-frequency transcranial random noise stimulation (hf-tRNS) to alleviate persistent symptoms, with the primary outcome being a 25% reduction in symptoms after 10 sessions.
The study aims to explore not only the clinical effects of hf-tRNS on symptoms like auditory hallucinations but also its impact on brain activity and cognitive functions, potentially establishing it as a new treatment option for patients resistant to traditional antipsychotics.

Bimodal repetitive transcranial magnetic stimulation (rTMS) significantly reduced symptoms of schizophrenia in 10 patients who were unresponsive to medication, with improvements noted in all subscales of the Positive and Negative Syndrome Scale (PANSS) by Day 29.
The treatment also showed potential benefits for short-term auditory verbal memory, as indicated by significant increases in neurocognitive test scores after the rTMS sessions.
Adjunctive treatment of bimodal repetitive transcranial magnetic stimulation (rTMS) in pharmacologically non-responsive patients with schizophrenia: a preliminary study.Oh, SY., Kim, YK.[2011]
In a study involving 16 patients with schizophrenia, high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) over the left dorsolateral prefrontal cortex did not show significant effects on negative symptoms compared to sham treatment.
While there was a trend for improvement in some symptoms with sham rTMS, the study concluded that HF-rTMS is not effective for treating negative symptoms of schizophrenia, suggesting the need for exploring alternative rTMS methods.
