NCT05526833

Brief Summary

This is an open-label extension study to continue to evaluate the safety, tolerability and efficacy of the Repetitive Transcranial Magnetic Stimulation (rTMS) in subjects with schizophrenia or schizoaffective disorder who previously completed the treatment study of the protocol #8116 (NCT05319080). Protocol #8116 investigates the clinical efficacy of open-label individualized MRI-guided TMS applied to the left temporoparietal junction (TPJ) in schizophrenia patients. Participating patients who have completed the 4-week project #8116 can be screened for eligibility for this extension study in which they will continue treatment/assessment. They will be divided into three groups (non-responders, partial responders, or full responders) based on a reduction in the Auditory Hallucination Rating Scale (AHRS) scores from the study #8116.

Outcome Measures

Primary Outcomes (3)

  • Total Number of rTMS Sessions Completed

    The total number of rTMS sessions completed for non responders and partial responders. A session is defined as 20 minutes of rTMS.

    2 weeks.

  • Total Number of Follow-up Clinical Assessments Completed

    The total number of follow-up clinical assessments completed for complete responders. A clinical assessment refers to answering questions about psychiatric symptoms to assess the sustainability of the patient's improvement from the previous study.

    8 weeks

  • Total Number of Treatment Emergent Adverse Events

    The total number of treatment emergent adverse events for non responders and partial responders. An emergent adverse event is defined as any rTMS risk induced incident in research such as headache and seizure.

    2 weeks.

Secondary Outcomes (7)

  • Change in Auditory Hallucination Rating Scale (AHRS)

    Up to 4/8 weeks.

  • Change in Psychotic Symptom Rating Scale (PSYRATS)

    Up to 4/8 weeks.

  • Change in Scale for the Assessment of Positive Symptoms (SAPS)

    Up to 4/8 weeks.

  • Change in Positive and Negative Syndrome Scale (PANSS)

    Up to 4/8 weeks.

  • Change in Cardiff Anomalous Perceptions Scale (CAPS)

    Up to 4/8 weeks.

  • +2 more secondary outcomes

Study Arms (3)

Non-responders undergo rTMS of the right superior temporal sulcus (STS)

EXPERIMENTAL

Non-responders to protocol #8116 will receive a type of TMS called repetitive TMS (rTMS) wherein the magnetic pulses delivered will be close together in a rapid sequence. They will be administered 10 days (10 sessions) of MRI-guided 1 Hz rTMS delivered to the right superior temporal sulcus (STS). The rTMS parameters that will be used are a frequency of 1 Hz (1 pulse per second) at an intensity of 90% of the motor threshold (MT). Therefore, the investigators will deliver 1200 continuous pulses per session/day which adds up to 12,000 pulses in total for the whole treatment.

Device: Repetitive Transcranial Magnetic Stimulation (rTMS)

Partial responders undergo rTMS of the left temporo-parietal junction (TPJ)

EXPERIMENTAL

Partial responders to protocol #8116 will receive a type of TMS called repetitive TMS (rTMS) wherein the magnetic pulses delivered will be close together in a rapid sequence. They will be administered 10 days (10 sessions) of MRI-guided 1 Hz rTMS delivered to the original left temporo-parietal junction (TPJ) target. The rTMS parameters that will be used are a frequency of 1 Hz (1 pulse per second) at an intensity of 90% of the motor threshold (MT). Therefore, the investigators will deliver 1200 continuous pulses per session/day which adds up to 12,000 pulses in total for the whole treatment.

Device: Repetitive Transcranial Magnetic Stimulation (rTMS)

Complete responders undergo four follow-up clinical assessments

NO INTERVENTION

Complete responders to protocol #8116 will be offered followup clinical assessments at 1, 2, 4, and 8 weeks to assess sustainability of their response.

Interventions

During the rTMS session, an electromagnetic coil is placed on the scalp of the subject's head. The electromagnet painlessly delivers a magnetic pulse that stimulates nerve cells in the region of the brain involved in speech perception.

SINGLE GROUP
Model Details: Schizophrenia patients with AVH who have completed protocol #8116 will be recruited, and allocated to one of three arms based on their treatment responsiveness from protocol #8116 which included 10 low-frequency TMS treatment sessions using the TPJ target. Their treatment responsiveness is assessed by the Auditory Hallucination Rating Scale (AHRS) at pre- and post-TMS session. Non-responders will be offered 10 daily sessions of 1-Hz rTMS delivered to the rSTS region instead. Partial responders will be offered 10 additional daily sessions of 1-Hz rTMS delivered to the same original left TPJ target used in protocol #8116. Full responders will be offered followup clinical assessments at 1,2,4, and 8 weeks to assess sustainability of their response.
