Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This project is a double blind randomized clinical trials that examines the efficacy of cerebellar non invasive stimulation for apathy improvement in patients with schizophrenia

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This double-blind RCT aims to explore the efficacy of intensiveTranscranial Magnetic Stimulation (TMS) in schizophrenia spectrum disorders. Previous studies in various disorders suggest that intensive TMS is efficacious and safe.

Participants will undergo neuronavigated intermittent theta burst TMS, targeted to individual network targets, at an accelerated protocol (multiple sessions a day), The primary goal is to determine the efficacy of this protocol in alleviating negative symptoms of schizophrenia.

Additionally, the study will measure the impact of accelerated TMS on a range of clinical and cognitive outcomes, along with neuroimaging markers indicative of symptom response.

Participants Caregivers Investigators Outcome Assessors
The subjects, care providers, investigators and outcome assessors will all be blinded as to the randomization sequence, and thus will be blinded as to sham vs active TMS status.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Active

Active intermittent theta burst stimulation (iTBS) to the cerebellum at 80% of active motor threshold.

Group Type ACTIVE_COMPARATOR

iTBS

Intervention Type DEVICE

Intermittent Theta Burst Stimulation (iTBS) pattern consisting of 2 s trains of 3 pulses at 50 Hz, repeated at 5 Hz, every 10s for a total of 600 pulses for up to 8 sessions daily for 5 days

Placebo

Sham intermittent theta burst stimulation (iTBS) to the cerebellum

Group Type PLACEBO_COMPARATOR

iTBS

Intervention Type DEVICE

Intermittent Theta Burst Stimulation (iTBS) pattern consisting of 2 s trains of 3 pulses at 50 Hz, repeated at 5 Hz, every 10s for a total of 600 pulses for up to 8 sessions daily for 5 days

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Capable of giving informed consent as evaluated by the treating psychiatrist
* Informed Consent signed by the subject
* Patients aged 18 - 65 years diagnosed with a schizophrenia spectrum disorder (including schizophrenia, schizoaffective or non-organic psychosis, psychotic disorder NOS) according to DSM-5 criteria
* Clinically stable condition judged by their treating psychiatrist
* Background antipsychotic medication treatments have remained unchanged for at least 4 weeks
* No hospitalization in acute psychiatry ward at least 3 months prior to study entry

Exclusion Criteria

* Comorbid and clinically active current major depressive episode determined by the treating psychiatrist.
* Active psychotic symptoms. In particular, patients that at Baseline have a PANSS scores of more than 4 in any of the following PANSS items: delusions, suspiciousness/persecution and hallucinatory behaviour will be considered not stable enough to participate.
* Significant extrapyramidal side-effects quantified by total score of mSAS \> 12.
* Increased sedation due to use of medication (slowing, drowsiness, slurred speech etc.)
* Active daily use of substances (i.e. cocaine), including for therapeutically medical purposes (e.g., methadone substitution)


* History of fainting spells of unknown or undetermined aetiology that might constitute seizures
* History of multiple seizures or diagnosis of epilepsy
* Any progressive (e.g., neurodegenerative) neurological disorder such as multiple sclerosis or Parkinson's disease
* Chronic uncontrolled medical conditions that may cause a medical emergency in case of a provoked seizure (cardiac malformation, cardiac dysrhythmia, asthma, etc.)
* Metallic objects/implants (excluding dental fillings) unless cleared to be MRI compatible (i.e. MRI compatible joint replacement)
* Any implants controlled by physiological signs in/near the head

* Pacemaker
* Implanted medication pump
* Vagal nerve stimulator
* Deep brain stimulator or TENS unit
* Ventriculo-peritoneal shunt
* Cochlear implant
* Impaired ability to sense heat/pain, open wounds etc.
* Increased intracranial pressure
* Intracranial lesion, from a known genetic disorder or from acquired neurologic disease (e.g. stroke, tumor, cerebral palsy, severe head injury, or significant dysmorphology).
* History of head injury resulting in prolonged loss of consciousness (\>15minutes) or neurological sequelae
* Ongoing pregnancy and breastfeeding. All participants capable of becoming pregnant will be required to have active contraception; any participant who is pregnant or breastfeeding will not be enrolled in the study.


* Clinically significant concomitant disease states (e.g., renal failure, hepatic dysfunction, cardiovascular disease, cancer, pulmonary decompensation etc.)
* Inability to follow the procedures of the investigation, e.g. due to language problems, psychological disorders, intellectual retardation, dementia, etc. of the subject
* Having legal obligation for psychiatric treatment.
* Participation in another investigation with an investigational drug or another MD within the 30 days preceding and during the present investigation.
* Previous enrolment into the current investigation
* Enrolment of the PI, his/her family members, employees and other dependent persons.
