Combining rTMS With Varenicline to Prevent Smoking Lapse in Schizophrenia

NCT03497299 · Status: WITHDRAWN · Phase: PHASE2 · Type: INTERVENTIONAL

Last updated 2023-09-06

No results posted yet for this study

Summary

Tobacco smokers with schizophrenia are known to be resistant smokers, with high rates of smoking and inability to quit in the long-term, often related to smoking relapse. This may relate to problems with frontal lobe function associated with schizophrenia, which make these patients have great difficulty in dealing with smoking withdrawal, urges and cravings. The current study will develop a combination approach that takes advantage of brain stimulation of the frontal lobes (repetitive transcranial magnetic stimulation (rTMS), in combination with the anti-smoking drug varenicline, to prevent smoking lapse using a well-established human laboratory method. Results from this study may have important implications for developing novel treatment approaches for smokers with schizophrenia.

Interventions

DEVICE

Active rTMS (20Hz)

Repetitive Transcranial Magnetic Stimulation (rTMS) Procedures: On Day 1, participants will be randomly assigned to receive active or sham rTMS using the MagProX100/R30 stimulator equipped with the B65 active/ placebo coil for DLPFC stimulator (MagVenture, Farum, Denmark) for a period of 28 days.

DEVICE

Sham rTMS

Repetitive Transcranial Magnetic Stimulation (rTMS) Procedures: On Day 1, participants will be randomly assigned to receive active or sham rTMS using the MagProX100/R30 stimulator equipped with the B65 active/ placebo coil for DLPFC stimulator (MagVenture, Farum, Denmark) for a period of 28 days.
