Primary Outcome Measures:
  • Time-to-lapse [ Time Frame: Week 2 pre quit day ]
    Two weeks after treatment is initiated, with nicotine patch + lorcaserin or nicotine patch alone, but still two weeks prior to the quit day, subjects will be evaluated in a modified version of the McKee Smoking Lapse Task. In this task smokers, who have been abstinent for 2 hours will be provided with the option to smoke at any time, but paid by the minute for remaining abstinent with progressively decreasing payments over an hour.

  • Smoking Withdrawal [ Time Frame: Week 2 pre quit day ]
    At the study visit above (two week post treatment initiation but 2 weeks prior to quit day), withdrawal symptoms will be assessed after 2 hours of smoking abstinence using the Shiffman-Jarvik questionnaire, which consists of 33-items rated from 1 to 7, where 1= not at all, 2= very little, 3= a little, 4= moderately, 5= a lot, 6= quite a lot, and 7= extremely. The 33 items are grouped into 8 subscales: Craving, Negative Affect, Appetite, Arousal, Somatic - Anxiety, Somatic - G.I., Somatic - Respiratory Tract, and Habit Withdrawal. The range of scores for each subscale will be 1-7, with higher scores indicating more of the withdrawal symptom having been experienced.


Secondary Outcome Measures:
  • Smoking Abstinence [ Time Frame: Weeks 7-10 post quit day ]
    Number of participants who reported continuous four-week abstinence from smoking (weeks 7-10 post target quit date), confirmed by expired air carbon monoxide (CO).

  • Tolerability [ Time Frame: Weeks 1-10 post quit day ]
    Tolerability of the lorcaserin + nicotine patch treatment will be assessed by tabulating the number of participants rating side effects > "moderate".

  • Weight Gain [ Time Frame: Week 10 post quit day ]
    Among smoking-abstinent participants, weight gain relative to baseline will be assessed.

  • 6-month Smoking Abstinence [ Time Frame: 6 months post Quit Day ]
    Number of participants who reported not smoking for the previous seven days when called for 6-month follow-up, confirmed by expired air carbon monoxide (CO).

  • Percentage of Change in Ad libitum Smoking at End of Week 2 [ Time Frame: Week 2 pre quit day ]
    To evaluate the effects of lorcaserin on ad libitum (ad lib) smoking, the percent decrease in reported number of cigarettes smoked from baseline to the end of week 2 (the day prior to the 2nd study visit) will be calculated.

  • Adherence [ Time Frame: Weeks 1-10 post quit day ]
    Tolerability of the lorcaserin + nicotine patch treatment will be assessed by calculating adherence scores based on the number of days on which the study drugs were taken as directed between visits as reported by participants on diaries.

Arms Assigned Interventions
Experimental: 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.
Drug: lorcaserin
Other Name: Belviq
Drug: nicotine patch
Other Name: Nicoderm
Experimental: 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.

Other Name: placebo Belviq

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.
