Modulating Neural Mechanisms of Reward Processing in Tobacco Users (ModRewTob)

2026년 9월 4일 업데이트: Travis Baker, PhD, Rutgers, The State University of New Jersey

The goal of this clinical trial is to learn if a personalized, brain-scan-guided form of transcranial magnetic stimulation (TMS) works better than a standard TMS approach at changing reward-related brain activity in adults who smoke cigarettes. The main questions it aims to answer are:

Does personalized TMS produce a greater change in reward-related brain activity than the standard approach? Does personalized TMS lead to a greater reduction in cravings and cigarette smoking than the standard approach?

Researchers will compare personalized TMS, which targets a treatment location chosen from each participant's own brain scan, to a standard TMS approach, which targets a location based on anatomical landmarks, to see if the personalized approach produces stronger effects on brain reward activity and smoking behavior.

Participants will:

Complete an magnetic resonance imaging (MRI) brain scan and questionnaires about their smoking habits and mood Be randomly assigned to receive either personalized TMS or the standard TMS approach Attend 15 TMS treatment sessions over 3 weeks (Monday through Friday), including brain wave (EEG) recordings and craving check-ins before and after each session Return for follow-up visits 1 week and 1 month after finishing treatment

상세 설명

People with tobacco use disorder often show changes in how their brain responds to rewards. A brain region involved in this process can be measured using a brain wave (EEG) signal that reflects how strongly the brain reacts to rewards. This study looks at whether a personalized form of brain stimulation can shift that signal more effectively than a standard approach.

The personalized approach, Pathway-precise Reward Intervention via Midcingulate Engagement (PRIME) TMS uses each participant's own brain scan to find the stimulation location that is most strongly connected to the brain's reward center, rather than using the same general location for everyone. Stimulation is also paired with a short reward-based computer task during the session, based on the idea that engaging the brain's reward system during stimulation may strengthen its effects. The standard approach uses a fixed stimulation location based on external head landmarks and is delivered without any task.

Participants are randomly assigned to one of the two approaches, similar to a coin flip, with the assignment balanced to make sure both groups have similar mixes of smoking severity and mood symptoms. Both groups receive the same number of sessions (15), on the same schedule (weekdays for 3 weeks), and the same strength and dose of stimulation. The only differences are where the stimulation is delivered and whether participants complete a task during it.

Study visits include an initial screening, a brain scan to plan the intervention, a baseline visit with brain wave recording and questionnaires, the three weeks of stimulation sessions, a follow-up assessment shortly after the sessions end, and two brief check-in calls at 1 week and 1 month later. Throughout the study, the research team monitors participants closely for side effects using standardized safety checklists, and all equipment used (the stimulation device, positioning system, brain wave recorder, and MRI scanner) is already cleared by the FDA for other uses.

The study will compare how much each approach changes brain reward activity, cravings, and smoking amounts, and will look at whether changes in brain activity help explain any changes in cravings or smoking behavior.

실험적: PRIME TMS (Personalized Connectivity-Based Targeting)
Participants receive 15 sessions of 10 Hz repetitive TMS over 3 weeks (Monday-Friday), delivered at 110% of resting motor threshold. The stimulation target is an individualized dorsolateral prefrontal cortex location identified from each participant's diffusion-weighted MRI as having maximal structural connectivity to the midcingulate cortex. Stimulation is delivered concurrently with a brief reward-based cognitive task performed during inter-train intervals, intended to engage the brain's reward circuitry during treatment.
장치: PRIME TMS
Repetitive TMS (10 Hz, 3,000 pulses per session, 110% resting motor threshold) delivered via a figure-8 coil using robotic neuronavigation. The stimulation target is an individualized dorsolateral prefrontal cortex location identified from each participant's diffusion-weighted MRI as having maximal structural connectivity to the midcingulate cortex. Delivered over 15 sessions across 3 weeks, concurrently with a brief reward-based cognitive task performed during inter-train intervals.

예

IPD 계획 설명

De-identified individual participant data will be shared, including: structural and diffusion-weighted MRI data; EEG recordings collected during the reward-based task at baseline and post-intervention; behavioral performance data from the reward task and the Probabilistic Selection Task; and questionnaire-based measures of craving (TCQ, QSU-B), smoking behavior (cigarette consumption, carbon monoxide levels), and nicotine dependence severity (FTND). All data will be stripped of direct identifiers, dates, and geographic identifiers smaller than state level prior to sharing, consistent with NIH data-sharing requirements.

IPD 공유 기간

Data will be prepared for repository deposit and made available beginning 12-18 months after study completion, or upon publication of primary results, whichever occurs first. Once deposited, de-identified data will remain available indefinitely, consistent with NIH data-retention requirements for de-identified research data. No end date is specified for data availability.

IPD 공유 액세스 기준

Access will be limited to qualified researchers who submit a data use request through the applicable repository (OpenNeuro for neuroimaging data; NIMH Data Archive for behavioral, EEG, and questionnaire data). Applicants must agree to the repository's data use agreement, restricting use to approved research purposes and prohibiting re-identification attempts. Requests are reviewed and approved by repository administrators, not directly by the study team.
