The Safety and Effectiveness of dTMS for Reducing Antipsychotic-induced Weight Gain (dTMS)

1 września 2026 zaktualizowane przez: Ping Shao, Second Xiangya Hospital of Central South University

The Effects of Improving Antipsychotic-induced Weight Gain by Accelerated dTMS After Food Cue-induced Craving, A Double-Blind, Randomized, Sham-Controlled Clinical Trial.

Antipsychotic-induced metabolic disturbances, especially weight gain, are common in patients with schizophrenia. There are no hitherto effective treatments for reducing antipsychotic-induced weight gain. Recently, research suggest that Accelerated dTMS (a-dTMS) which deliver more than one daily TMS session indicates greater efficacy than other TMS treatment. Symptom provocation is believed to improve the clinical responses to TMS. In this study, the investigators, firstly, evaluate the safety and effectiveness of a-dTMS for reducing antipsychotic-induced weight gain and secondly, to establish a predictive model of therapeutic response and to explore the underlying mechanisms of dTMS for reducing antipsychotic-induced weight gain, based on multimodal radiomics and metabolomics approaches.

Szczegółowy opis

The underlying causes of antipsychotic-induced weight gain are still unknown. Some research point out that it has something to do with metabolic disturbances and changes in appetite and food intake, acting food-craving-like behave which some points are similar to addiction. With fMRI study, it is reported having dysfunction between prefrontal and insula cortex of its cognitive regulation, interoceptive signals and reward control. dTMS, H coil in particular, simultaneously targets prefrontal and insula cortex, approved by FDA for Smoking Addiction recently. Previous study has been deconstrued that H coil could significantly improve weight gain than figure-eight Coils. Moreover, It is reckoned that TMS has state-dependent effects on brain circuitry, suspected that symptom provocation may be made it more susceptible to modulation which may improve response. Therefore, this study is to explore the efficacy of a-dTMS on antipsychotic-induced appetite, and use multimodal radiomics and metabolomics approaches to unveil the underlying mechanisms of dTMS for reducing antipsychotic-induced weight gain.

With regard to investigate this, we will be carried out a randomized, double-blind, sham-controlled clinical trial. 60 Patients with schizophrenia will be randomly treated with active a-dTMS or sham condition for 3 sections' interventions per day last for 10 days. The follow-ups are at baseline, the 12th day and the 42th day after the end of treatment. The main outcome measures include the change in body weight, BMI, TFEQ score, FCQ-S score, FCQ-T score and the resting and task-state EEG-fMRI imaging data.

Eksperymentalny: a-dTMS stimulation
The patients in a-dTMS stimulation group will receive accelerated intermittent theta burst stimulation (ACC-iTBS) stimulation for 10 consecutive days and 3 times per day. There will have at least 50 minutes interval between each intervention. Participants will be undertaking symptom provocation named food cue induced craving before each stimulation.
The intensity of the stimulator is set at 80% of resting motor threshold (RMT), and the other parameters are set to triplet 50Hz bursts, repeat at 5Hz, 2s seconds on and 8 seconds off, 1800 pulses per session, total duration of 9 minutes and 52 seconds.
Pozorny komparator: Sham stimulation
The participants in sham stimulation will receive sham coil stimulation for 10 consecutive days and 3 times per day. There will have at least 50 minutes interval between each intervention. Participants will be undertaking symptom provocation named food cue induced craving before each stimulation.
The same procedure will be performed in sham coil induced acoustic and scalp sensations similar to those induced by the active coil, but without electromagnetic penetration into the brain and without neural activation.

Change in Three Factor Eating Questionnaire (TFEQ)
Ramy czasowe: Change in TFEQ between baseline and the end of the treatment (day 12) and follow-up (day 42)
The Food Cravings Questionnaire-Trait (FCQ-T) is a self-reported measures which is a 39-item questionnaire that has nine subscales: intentions and plans to consume food, outcome expectancy of positive reinforcement, outcome expectancy of relief from negative states, anticipated lack of overeating control, preoccupation with food, physiological deficits and responses which may elicit craving, emotions experienced during food craving, external and internal cues that trigger cravings, and guilt.
Change in TFEQ between baseline and the end of the treatment (day 12) and follow-up (day 42)
Change in Food Cravings Questionnaire-Trait (FCQ-T)
Ramy czasowe: Change in FCQ-T between baseline and the end of the treatment (day 12) and follow-up (day 42)
The change of food craving will be evaluated by Food Cravings Questionnaire-Trait (FCQ-T), a self-report multidimensional questionnaire composed of 39 items aimed to investigate food addiction and eating disorders. Total FCQ-T score will be used as a general measure of trait craving; individual FCQ-T scores related to the 9 measured craving dimensions could be useful in identifying and differentiating craving profiles between specific populations.
Change in FCQ-T between baseline and the end of the treatment (day 12) and follow-up (day 42)
Change in Food Craving Questionnaire State (FCQ-S)
Ramy czasowe: Change in FCQ-S between baseline and the end of the treatment (day 12) and follow-up (day 42)
The Food Craving Questionnaire-State (FCQ-S) is a 15-item self-report measure to assess momentary, state-dependent food craving. The instrument consists of five multidimensional subscales: (1) intense desire to eat, (2) anticipation of positive reinforcement from eating, (3) anticipation of relief from negative states and feelings as a result of eating, (4) lack of control over eating, and (5) craving as a physiological state. Respondents rate each item on a 5-point Likert scale ranging from 1 ("strongly disagree") to 5 ("strongly agree"). Total scores are calculated by summing all 15 item responses, yielding a possible range of 15 to 75. Higher total scores indicate more intense current state food cravings.
Change in FCQ-S between baseline and the end of the treatment (day 12) and follow-up (day 42)
Change of Visual Analogue Scale, VAS
Ramy czasowe: Change in VAS between each food cue induced craving and food cue reactivity before and after
The VAS is a simple, quick-to-administer, and sensitive instrument for detecting acute fluctuations in food craving, hunger, and related motivational states in response to food cue exposure. In the context of food cue reactivity, the VAS is administered immediately before and after presentation of food stimuli (e.g., pictorial food cues, actual food exposure, or virtual reality food environments) to capture acute changes in craving, hunger, appetite, and related motivational states. The VAS consists of a 100-mm horizontal line anchored at each end by verbal descriptors representing the extremes of the construct being measured, typically ranging from 0 ("not at all" or "no desire at all") to 100 ("extremely" or "very strong desire").The score is determined by measuring the distance in millimeters from the left anchor to the respondent's mark, yielding a possible range of 0 to 100, with higher scores indicating greater intensity of the measured construct.

Change in parameters of the Stop Signal Task, SST
Ramy czasowe: Change in parameters of SST between baseline and the end of the treatment (day 12) and follow-up (day 42)
The SST aims to access cognitive behavioral inhibition control. The study employed a task that comprised randomly interleaved NoGo and Stop-Signal trials to examine both types of inhibition. The study measured six behavioral parameters of interest: namely Mean Go reaction time (GoRT), Stop-Signal mean reaction time (SSRT), Stop-Signal delay (SSD), Target accuracy, Go trial accuracy, and NoGo Accuracy. The primary outcome measure derived from the SST is the stop-signal reaction time (SSRT) , which is an estimated measure of the speed of the inhibitory process. The SSRT is calculated by subtracting the mean or median stop-signal delay (SSD) from the mean or median reaction time on go trials. Higher SSRT values indicate longer inhibition latency and thus poorer inhibitory control, whereas lower SSRT values indicate faster inhibition and better inhibitory control.

Change in parameters of the Go/No-Go Task (GNG)
Ramy czasowe: Change in parameters of GNG between baseline and the end of the treatment (day 12) and follow-up (day 42)
The Go/No-Go Task (GNG) is a computerized behavioral paradigm that measures response inhibition-specifically, the ability to withhold a prepotent motor response to a frequently occurring stimulus when an infrequent, conflicting stimulus occurs.The GNG task comprises two types of trials presented in random order: Go trials (typically 70-80% of all trials) and No-Go trials (typically 20-30% of all trials).The most critical outcome derived from the GNG task is the No-Go error rate, calculated as the number of incorrect responses on No-Go trials divided by the total number of No-Go trials. Higher No-Go error rates indicate poorer inhibitory control.

Change in Blood laboratory parameters
Ramy czasowe: Change in Blood laboratory parameters between baseline and the end of the treatment (day 12) and follow-up (day 42)
About 20ml blood samples were collected intravenously to test blood routine, liver and kidney function, electrolytes and other routine tests. Changes in lipid metabolism will be evaluated by Cholesterol (mg/dL), Triglycerides (mg/dL), High-Density Lipoprotein Cholesterol (mg/dL), Low-Density Lipoprotein Cholesterol (mg/dL), Fasting Blood Glucose (mmol/L).
