Detaljeret beskrivelse
This will be a multi-site, open-label, randomized controlled trial to evaluate the rate of end of study (EOS) smoking abstinence of healthy adult consumers of combustible cigarettes (CC) when provided an electronic nicotine delivery system (ENDS) over a 13-week study period.
Potential participants will be recruited and enrolled at multiple sites across the U.S. They will complete a pre-screening questionnaire to assess their study eligibility approximately 60 days prior to enrollment. Participants who meet pre-screening criteria will provide an informed consent to attend a screening and enrollment visit (SEV), which is a mandatory site visit (MSV) during which participants will be screened, and eligible participants will be randomized to one of the three study arms.
Participants will begin the study with a one-week Trial Period. This Trial Period will allow participants to sample the available flavor(s) within their Study Arm.
All participants will attend MSV on Days 0, 30, 60, and 90 with the option of changing to a different flavor among the available flavors based upon their assigned Study Arm, if applicable. In the first 4-weeks of the study, participants in Study Arms 1 and 2 may also attend optional site visits (OSV) on Days 7, 14, and 21, with the option of changing flavors to a different flavor among the available flavors in their assigned Study Arm. During the 13-week study period, participants will be free to use the ENDS and any other tobacco or nicotine products as desired. The ENDS Version 2 Power Unit technology will measure their puffing topography during use (puff duration and inter-puff interval). Participants will be invited to complete daily, weekly, and monthly surveys, using a mobile application installed on their own smart phones. Surveys will collect data on the number of CC smoked the previous day, current flavor use, product liking, number of cigarette quit attempts, and any other tobacco or nicotine products used, intent to substitute their UB CC for the Study IP and social/environmental factors influencing switching intent. At the conclusion of the study period, all participants will return to the sites for a close out period and will be discharged from the study. Safety and adverse events/experiences (AEs) will be monitored throughout the study via a safety Hotline.
