Study Details

Brief summary:

Tobacco smoking is the leading preventable cause of morbidity and mortality worldwide. However, currently available treatments, including standard pharmacotherapy and behavioural support, are limited in their efficacy, tolerability, and acceptability by patients. Additionally, tobacco use is substantially higher in individuals with comorbid mental illness, constituting a particularly vulnerable population. As such, the development of multiple evidence-based treatments for smoking cessation is of upmost importance.

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain-based approach in which alternating magnetic fields are applied to the scalp to induce electrical currents in cortical tissue. As it can modulate neural circuits implicated in neuropsychiatric disorders, it is a promising brain-based approach in the treatment of substance use disorders. Recently, a deep TMS coil has been cleared by the Food and Drug Administration (FDA) as efficacious for tobacco use disorder, representing the first rTMS indication for addictions. Before adoption of this intervention into smoking cessation clinics, it is important to investigate whether implementation of rTMS into clinical care is feasible, acceptable, and appropriate for patients receiving care for nicotine dependence.

The objective of this study is to compare the effectiveness of rTMS versus treatment as usual for patients with psychiatric disorders seeking treatment for smoking cessation. Also, barriers to the implementation of rTMS in routine clinical care will be examined by speaking with patients and health care providers on their experience with rTMS.

10. Currently using or has used nicotine replacement therapy within the past two weeks.
11. Diagnosed with a terminal illness
12. Current regular use of e-cigarettes or other vaping devices containing nicotine and not willing to stop using these devices for the duration of the study.

Interventions and Outcome Measures

Arms

experimental: Repetitive Transcranial Magnetic Stimulation (rTMS) Intervention

Treatment course consisting of daily treatment, 5 days per week, for 3 weeks, followed by once weekly treatments for 3 weeks, for a total of 18 treatment sessions over 6 weeks.

active comparator: Treatment as Usual

Treatment with Nicotine Replacement Therapy (NRT) and/or adjunctive counselling will be provided by their clinical team through the Smoking Treatment for Ontario Patients (STOP) Program. All treatments will be delivered by study physicians in the Nicotine Dependence Clinic at CAMH, all of whom administer NRT through the STOP program.

Interventions

Brainsway H4 deep Repetitive Transcranial Magnetic Stimulation (rTMS) coil

An rTMS treatment course consisting of daily treatment, 5 days per week, for 3 weeks, followed by once weekly treatments for 3 weeks, for a total of 18 treatment sessions over 6 weeks.

Sixty trains of 30 pulses each (total 1,800 pulses) will be applied at 10 Hz, for 3 second trains, with a 15 second inter-train interval, for approximately 18 minutes of treatment time.

At each rTMS treatment session, prior to stimulation, participants will undergo a smoking craving provocation procedure where they will be asked to close their eyes and imagine one of their triggers for 30 seconds. Following this they will watch a presentation of smoking pictures for 2 minutes and 30 seconds. Thus, the entire craving provocation procedure will be 3 minutes prior to stimulation start.

Brief behavioural support will be available to the participant on a weekly basis by a trained research staff member.

Nicotine replacement

Each participant will receive individualized NRT treatment through the advice of their study physician for 6 weeks. The study physician, in discussion with the participant, will decide the type, dosage, and combination of NRT to provide to the participant.

NRT provided can include:

  • Patch (7mg, 14mg, and 21mg)
  • Gum (2mg)
  • Lozenge (2mg)
  • Inhaler (10mg; 4mg of nicotine delivered)

Primary outcome measure

  • Evaluate the feasibility of conducting a pragmatic, hybrid effectiveness implementation trial of Repetitive Transcranial Magnetic Stimulation (rTMS) versus treatment as usual (TAU). [ Time Frame: Through study completion, an average of 2 years ]
