Not Applicable

Active, not recruiting

• Conditions: Smoking Cessation

• Registration Number: NCT06544772
• Lead Sponsor: Pivot Health Technologies Inc.

Brief Summary

Prospective, open label, single center clinical study enrolling up to 120 participants to evaluate the Pivot cigarette smoking cessation program in adult smokers, previously unable to quit, who also use other smoke-free nicotine product(s) (poly-use) and wish to stop cigarette smoking by switching to these smoke-free nicotine products.

Detailed Description

This is a prospective, open label, single center clinical study conducted with Institutional Review Board approval enrolling up to 120 adult participants who report cigarette smoking and concurrent use of smoke-free nicotine product(s), and wish to switch completely off cigarettes. The study will be performed remotely on an ambulatory basis.

Participants will be asked to set up and use the Pivot cigarette smoking cessation program which comprises a mobile personal breath carbon monoxide sensor (Pivot Breath Sensor) and a smartphone app (Pivot app) with in-app asynchronous text-based coaching with a certified human tobacco cessation coach. The study duration is 26 weeks, with main outcomes assessed at 12 weeks (primary endpoint) and 26 weeks. Participants will receive online questionnaires at intervals throughout the study. Participants who indicate abstinence from cigarette smoking at 12 weeks will be invited to do a video call biovalidation visit in which they perform an observed breath sample using their Pivot breath sensor.

Potential participants will complete an online screening form. Eligible participants will be called to confirm eligibility, discuss the study, and have their questions about the study answered. Interested eligible participants will complete the electronic informed consent form and baseline questionnaire prior to downloading the app on their smartphone.

The investigators aim to assess the performance of the Pivot program among adult smokers who also use other smoke-free nicotine products, with a focus on assessing trial feasibility, program acceptability, use and engagement, changes in attitudes towards switching from cigarettes to smoke-free nicotine products and changes in cigarette, nicotine product use, and carbon monoxide (CO) values over the course of the 26-week study, as well as participant feedback on the set-up, design, use experience, and impact of the program.

Secondary Outcome Measures

Name	Time	Method
Trial feasibility: study enrollment	Enrollment	Trial feasibility in study enrollment is assessed via 3 measures, the third being the proportion of unique (non-duplicate) online screening form completers who complete the screening phone call and enroll in the study. Enrollment is defined as completing the HIPAA authorization form and electronic informed consent form (ICF), the online baseline questionnaire, and registration in the Pivot app.
Interest in Switching	Baseline	Participants are asked: "How interested are you in completely switching from cigarettes to smoke-free nicotine products?". Participants are provided the following answers to choose from: "Extremely", "Somewhat", "Not interested".
