Brief Summary

This study plans to compare the efficacy of the nicotine patch / lorcaserin combination treatment vs. the nicotine patch alone in terms of leading to a reduction in smoking behavior and withdrawal symptoms.

Detailed Description

This study proposes to investigate the potential efficacy of a combination of two FDA-approved agents, nicotine patch and lorcaserin, for smoking cessation treatment. The nicotine patch which provides a sustained low dose of nicotine is a nicotine receptor agonist. Lorcaserin, a serotonin 5-hydroxytryptamine receptor 2C (5-HT2C) agonist, is a drug that is FDA-approved for weight loss, and has also recently been shown to be efficacious for smoking cessation. Given that these drugs act through distinct mechanisms it is hoped that the combination will prove more efficacious than either drug alone. It is also hypothesized that the combination will reduce weight gain commonly seen after smoking cessation.

Study Groups

Lorcaserin + Patch

Participants will receive lorcaserin (10mg twice a day) and nicotine patches (21mg/24hr) for 14 weeks, at which point the nicotine patch dosage will be reduced to 14mg/24hr for 1 week, followed by 7mg/24hr for 1 week.

Patch

Participants will receive nicotine patches (21mg/24hr) and placebo lorcaserin for 2 weeks; after 2 weeks participants will begin to receive active lorcaserin (10mg twice a day) along with the nicotine patches for 12 weeks, at which point the nicotine patch dosage will be reduced to 14mg/24hr for 1 week, followed by 7mg/24hr for 1 week.
