What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a non-invasive brain stimulation technique called TMS can change how the brain processes rewards in smokers. Researchers will compare different targeting methods to see which best boosts brain signals related to reward and decision-making. The goal is to find the optimal spot to stimulate, which could eventually help reduce cravings and support quitting. Thirty-six nicotine-dependent adults will participate in three sessions.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Transcranial magnetic stimulation (TMS) device
What this could lead to
If successful, this could identify the best brain target for TMS to reduce cravings and improve decision-making in smokers, pointing toward better addiction treatments.
What could go wrong
This is a small, early-phase study with only 36 participants, focused on brain activity measures rather than quitting smoking. Results may not lead to a practical treatment.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 36 people

The number the study aims to enrol. It can still change while the study runs.

Started

Mar 2023

Expected to finish

Sep 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 55 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Nicotine dependent individuals (according to the Alcohol, Smoking and Substance Involvement Screening Test nicotine dependence score). 2. Be between the ages of 18 and 55 years old. 3. Not received substance abuse treatment within the previous 30 days. 4. Be in stable mental and physical health. 5. If female, test non-pregnant. 6. No evidence of focal or diffuse brain lesion on MRI. 7. Be willing to provide informed consent. 8. Be able to comply with protocol requirements and likely to complete all study procedures. Exclusion Criteria: 1. Contraindication to MRI (e.g., presence of metal in the skull, orbits or intracranial cavity, claustrophobia). 2. Contraindication to rTMS (history of neurological disorder or seizure, increased intracranial pressure, brain surgery, or head trauma with loss of consciousness for \> 15 minutes, implanted electronic device, metal in the head, or pregnancy). 3. History of autoimmune, endocrine, viral, or vascular disorder affecting the brain. 4. History or MRI evidence of neurological disorder that would lead to local or diffuse brain lesions or significant physical impairment. 5. Life time history of mental disorders such as: Bipolar Affective disorder (BPAD), Schizophrenia, Post-traumatic Stress disorder (PTSD) or Dementia or Major Depression. 6. uninterruptable central nervous system medication
