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.
Detailed Description:
The optimal neuroanatomical treatment targets remain unclear, though current neuroscience evidence suggests several brain areas such as the left temporo-parietal junction area (TPJ) or the right posterior superior temporal sulcus (rSTS) may be involved in the generation and development of AVH. During this extension study, non-responders to protocol #8116 will be administered 10 days (10 sessions) of MRI-guided 1 Hz rTMS delivered to the rSTS instead of the original target in TPJ. Partial responders will receive 10 additional low-frequency rTMS over the original left TPJ target. Like the protocol #8116, the investigators will use the MRI-guided targeting approach during rTMS treatment sessions to achieve greater precision as it can account for individual differences in anatomy. Complete responders will instead be followed for sustainability of response. Their clinical ratings will be repeated at one week, two week, four week and eight week follow-ups. Non-responders are defined as patients showing a reduction of AHRS less than 20% of the initial score. A partial response is defined as a reduction in a range of between 20% and 50% of the initial AHRS score. A complete response is defined as a reduction by at least 50% of the initial AHRS score.The combined outcome of protocol #8116 and the currently proposed protocol will help guide TMS targeting and the number of treatment sessions for a future larger randomized, double-blinded, shame-controlled clinical trial.
