Gender Differences in Response to Nicotine Replacement Therapy and De-Nicotinized Cigarettes
In Brief
A Phase 2 clinical trial evaluating nicotine patch (Nicoderm Committed Quitter (CQ), Habitrol) and denicotinized cigarettes (Quest 3 cigarettes) for Nicotine Dependence. Completed, enrolled 33 participants across 1 site.
Detailed Summary
This study will investigate the underlying neurobiology of differences between male and female smokers. Research suggests that women are less responsive to nicotine replacement therapy (NRT) than men and more responsive to the sensory and behavioral aspects of smoking. This study proposed that male smokers will have a greater response to NRT demonstrated by reduced withdrawal symptoms, craving, and less blood-oxygen-level dependent functional magnetic resonance imaging (BOLD FMRI) regional brain activation in response to nicotine-cues as compared to female smokers treated with NRT. Additionally, female smokers will have a greater response to denicotinized cigarettes with decreased withdrawal symptoms, craving, and less BOLD fMRI activation in response to nicotine-cues as compared to male smokers.

Timeline
Interventions
