Brief Summary:
Transdermal nicotine delivery systems are a cigarette smoking cessation aid designed to deliver nicotine into the systemic circulation via the skin. They have been found to reduce craving, thereby enhancing a patient's success for quitting smoking. However, side effects such as sleep disturbances and skin irritation, as well as incomplete smoking cessation are commonly experienced by users of such systems. Chrono Therapeutics, Inc. has developed an innovative programmable transdermal drug delivery system called the Chrono Quit Smoking Solution (CQSS2) that provides "off" periods (periods in which little to no nicotine is delivered), which is an advantage over existing systems that currently provide continuous delivery. The most important features of the CQSS2 are the periodic automatic dosing, plus the reduced side effects of sleep disturbances and potentially, skin irritation. The period when less nicotine is being delivered through the skin allows the skin an opportunity to "recover", thereby potentially reducing skin irritation. Another major benefit is the automatic dosing, which provides higher drug dosage at specific times of the day, leading to potentially greater success in quitting smoking. In this study, the CQSS2 will be used in conjunction with the Digital Coach application (app). The Digital Coach is a custom mobile app that provides behavioral support for the CQSS2. Together, the CQSS2 and the Digital Coach comprise the CQSS2 System.

Condition or disease Intervention/treatment Phase
Smoking Cessation Drug: CQSS2 Drug: NicoDerm CQ Patch Phase 2

Detailed Description:

Study EF2016-003 is a Phase 2, randomized, two-arm, open-label, multicenter efficacy and safety study of the CQSS2 System for smoking cessation over a 6-week treatment period in healthy treatment-seeking subjects who are smokers.


To evaluate quit rates (continuous abstinence from smoking during the last 4 weeks of treatment [Visit 3 through the end of study treatment]) in smokers (more than 10 cigarettes/day) being treated with the CQSS2 System versus NicoDerm® CQ® patch


To assess the safety and tolerability of the CQSS2 System

Arm Intervention/treatment
Experimental: CQSS2 System (nicotine 21 mg)
Active CQSS2 System (nicotine 21 mg) with Digital Coach. One active Drug Cartridge will be used to transdermally administer 21 mg nicotine via a 5.4% w/v solution in an aqueous EtOH mixture per day. Metered pulses of 125 µL of solution will automatically be delivered by the assembled CQSS2 (containing the Control Unit and Drug Cartridge) at Time = 0, 0.5, 1, 7, 7.5, and 13 hours.
Drug: CQSS2
Nicotine Replacement Therapy
Other Name: Chrono Quit Smoking Solution

Active Comparator: NicoDerm® CQ® patch (21 mg)
NicoDerm® CQ® patch (21 mg) with The NicoDerm patch transdermally administers 21 mg of nicotine per day. The NicoDerm patch is applied each morning of the treatment period after waking and worn for approximately 24 hours.
Drug: NicoDerm CQ Patch
Nicotine Replacement Therapy
Other Name: Nicotine patch

Primary Outcome Measures :
  1. Quit Rates for Smokers treated with the CQSS2 System vs NicoDerm CQ Patch [ Time Frame: continuous abstinence from smoking during the last 4 weeks of treatment [Visit 3 through the end of study treatment]) in smokers (more than 10 cigarettes/day) ]
    Quit rates will be assessed by subject self-reporting, confirmed by Smokerlyzer testing, and documented by the Tobacco Outcome Measures Assessment. The Smoking Self Efficacy Questionnaire (SEQ12) will measure the subject's perceived ability to quit smoking.

Secondary Outcome Measures :
  1. Number of participants with treatment-related adverse events as assessed on an 8-point Skin Irritation Assessment scale (0 to 7) [ Time Frame: From the time of the study drug application (6 week study period) until the last Follow-up visit. ]
    Any score of ≥3 will be reported as an AE

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

To be eligible for study participation, subjects must meet the following inclusion criteria:

  1. Ability to participate fully in all aspects of the study.
  2. Ability to understand and sign the study informed consent form.
  3. English-speaking, literate males and females.
  4. Age ≥18 years.
  5. Smokers consuming on average >10 cigarettes per day for the past 6 months, confirmed by self report.
  6. Carbon monoxide (CO) level ≥10 ppm, as determined by a Smokerlyzer breath test.
  7. Subject is in good health as determined by the Investigator.
  8. Subject has no known issues with completing all study visits.
  9. Subject must have regular access to Verizon Wireless at home as verified by or, at home wifi, or known connectivity to Verizon Wireless.

Exclusion Criteria:

Subjects will be excluded from this study if they do not fulfill the inclusion criteria, or if any of the following conditions are observed:

  1. Subjects with screening clinical laboratory tests (complete blood count [CBC] with differential and platelets, and chemistry profile) outside the normal range and considered to be clinically significant by the Investigator.
  2. Subjects with severe hepatic, renal, cardiovascular, endocrine, or hematologic diseases who demonstrate abnormal electrolyte, hematology, and/or liver function (albumin, total protein, bilirubin) results on the screening blood laboratory tests, or with a history or illness that may (in the opinion of the Investigator) confound the results of the study or pose additional risk. Because these disorders may occur either alone or in combination, this judgment is left to the discretion of the Investigator caring for the subject.
