Clinical Trial Summary

Electronic Nicotine Delivery Systems (ENDS), commonly referred to as electronic cigarettes have gained in popularity over the last several years. The technology used to manufacture ENDS has been evolving rapidly with a variety of delivery mechanisms, nicotine content, e-liquids and flavorings. Only in the last few years have researchers begun to examine the health risks and benefits, nicotine blood levels, patterns of use, likability, and craving and withdrawal relief of ENDS. These studies have shown great variability in nicotine delivery, effects on heart rate, and relief of craving or withdrawal among various ENDS brands among tobacco cigarette smokers.

This study will test a new generation ENDS, the NJOY King Bold (NJOY, Scottsdale, AZ). It is a single use unit that resembles a traditional cigarette and delivers approximately 150 puffs. The cartridge inside contains 26 milligrams of nicotine.

Our primary objective is to evaluate the short-term effects of using the NJOY Kings ENDS on heart rate, carbon monoxide and blood nicotine levels and well as on craving for cigarettes and nicotine withdrawal. Our secondary objective is to evaluate the subject's usage patterns for cigarettes and NJOY King ENDS during a one-week period in which they can use each freely.

The study includes three visits to the clinic spaced approximately one week apart. Subjects who pass the screening visit will return to the clinic for Visit 2 in which they will sample the NJOY King ENDS for about 20 minutes before taking home enough to last till Visit 3, one week later. They will be instructed to use as many or as few as they like during the week. Subjects will keep a daily diary of number of tobacco cigarettes smoked and number of e-cigarette puffs taken. Subjects will return to the clinic for Visit 3 after 12 hours of abstinence from any form of nicotine in order to assure that they have no nicotine left in their bloodstream. Eligible subjects will then participate in two series of 10 puffs of NJOY Kings spaced one hour apart. During the 2.5 hours of the testing day, the following will be measured: 1) heart rate, 2) carbon monoxide, 3)blood will be sampled for nicotine levels, 4) craving for cigarettes and nicotine withdrawal symptoms will be assessed.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in blood nicotine levels	Note: Visit 3 can occur up to 28 days after the Screening Visit	Change from baseline at Visit 3 to 5, 10, 15 and 30 minutes after each of two series, spaced one hour, apart of 10 puff from the NJOY King at Visit 3	Yes
Primary	Change in average cigarettes smoked per day	Subjects will have a one weeks supply of NJOY Kings to use as they like. Mean cigarettes per day during the "actual use week" will be compared to the mean cigarettes per day for the baseline week (which is one week before the "actual use" week)	The baseline week compared to the week testing the NJOY Kings in the "real world"	No
Primary	Average NJOY Kings puffs used per day	Mean number of puffs per day of NJOY King ENDS used during Day 1 through Day 6 of the actual use week which can begin 1 to 3 weeks after the Screening Visit	Day 1 through Day 6 of the of testing the NJOY Kings in the "real world"	No
