The US Food and Drug Administration (FDA) has granted marketing approval for the BrainsWay deep transcranial magnetic stimulation (TMS) system to help adult smokers kick tobacco.
This is the company's third FDA-approved indication for its deep TMS system and the first FDA approval for any TMS device for addiction, the company said in a press release.
The BrainsWay deep TMS system with H4-coil is designed to target addiction-related brain circuits.
It was evaluated as an aid to short-term smoking cessation in a prospective, double-blind, randomized, sham-controlled, multicenter study that involved 262 adults who had a history of smoking an average of more than 26 years and had attempted to quit multiple times but failed.
Active and sham treatments were performed daily 5 days a week for 3 weeks, followed by an additional three sessions once weekly for 3 weeks, for a total of 18 sessions over 6 weeks.
In the full intention-to-treat population (all 262 participants), the 4-week continuous quit rate (CQR, the primary endpoint) was higher in the active deep TMS group than in the sham TMS group (17.1% vs 7.9%; P = .0238).
Among participants who completed the study ― ie, those who underwent treatment for 4 weeks, kept daily records, and for whom confirmatory urine samples were available – the CQR was 28.4% in the active deep TMS group, compared to 11.7% in the sham treatment group (P = .0063).
The average number of cigarettes smoked per day, as determined on the basis of daily records (secondary endpoint), was statistically significantly lower in the active deep TMS group compared to the sham treatment group (P = .0311).
No patient suffered a seizure. The most common adverse event was headache, for which there was no statistical difference between the active and sham treatment groups. Other side effects included application site discomfort, back pain, muscle twitching, and discomfort.
"This FDA clearance represents a significant milestone for BrainsWay and our deep TMS platform technology," Christopher von Jako, PhD, president and CEO of the company, said in the release.
"While other therapies are currently available, a substantial medical need continues to exist for treatments that can increase the continuous quit rate among smokers," von Jako noted.
"Based on the compelling data from our large, randomized pivotal study of 262 subjects, we are confident that our deep TMS technology can play an important role in treating cigarette smokers who seek to quit," he added.
The company plans a "controlled" US market release of the system for this indication early next year.
