Personalized Dosing of Nicotine Replacement (NRT to Effect)
Personalized Dosing of Nicotine Replacement for Smoking Cessation: An Effectiveness Randomized Placebo-controlled Trial

Intervention / Treatment
Detailed Description
A total of 500 smokers will be enrolled from two smoking cessation clinics to participate in this study. After 2 weeks of usual treatment with 21mg patch, participants who fail to quit smoking will be randomized to receive either escalating doses of active nicotine patches, or placebo patches, for 10 weeks. Those who stop smoking during the first 2 weeks of usual treatment will continue with 21mg patch treatment for 10 weeks as an additional comparison group. In addition to the medication, participants in all groups will receive brief behavioral counselling. Subjects will return to the clinic at weeks 26 and 52 to assess whether or not they are still abstinent from smoking and self-reports of non-smoking will be confirmed using a urine test for nicotine by-product (cotinine) levels. Exhaled carbon monoxide (CO) will be recorded as an additional measure. Study follow-up visits can be conducted virtually if needed.
The goal of the proposed study is to optimize the current gold standard smoking cessation treatment (nicotine patch plus brief counseling) in order to further increase quit rates. Evidence supporting the effectiveness of personalized doses of NRT could change current practice in a wide variety of healthcare settings. Given the strong link between smoking and cancer, and evidence that quitting smoking at any age diminishes this risk, even small increases in absolute quit rates can have a substantial population-level impact on reducing the incidence of smoking-related cancers, reducing mortality rates and associated healthcare costs.
