CONQUER: quitting nicotine by gradually reducing e-cigarette nicotine with filters and a sensory support device

Official title: The CONQUER Trial: Cessation Of Nicotine, QUitting With E-cigarette Reduction - A Single-Arm, Open-Label Clinical Trial to Assess the Efficacy of VapeAway in Promoting Vaping Cessation Compared to Historical Rates of Vaping Cessation

Run by VapeAway · NCT07322432 · Data updated 2026-11-12

This project tests whether the VapeAway system—progressive nicotine-tapering filters, a Fix Bar sensory device, and digital support—can help motivated adult daily e-cigarette users quit nicotine.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 21 and older who vape nicotine daily or near-daily, have saliva cotinine ≥10 ng/mL, a PSECDI score ≥4, and demonstrate strong motivation and readiness to quit.

Probably not a fit

People who are not motivated to quit, who use only non-nicotine e-cigarettes, who cannot attend required visits, or who meet exclusionary mental health or concurrent-product criteria are unlikely to benefit from this intervention.

What this trial studies

CONQUER is a Phase II, single-arm, open-label, multi-center trial planned to enroll about 70 adults who vape nicotine daily and are motivated to quit. Participants complete a roughly 42-day core VapeAway program (±21 days) using progressive nicotine-tapering filters, a behavioral Fix Bar substitution device, and structured digital support, with total follow-up of about 90 days. The primary endpoint is Continuous Abstinence Rate (CAR) at 30 days post-intervention compared to a historical spontaneous cessation rate of ~7%; secondary outcomes include saliva cotinine, vaping frequency, withdrawal symptoms, and dependence scores. Eligibility requires biochemical confirmation of nicotine use, a minimum dependence score, and high readiness to quit, and all participants receive the active intervention.

Why it matters

Potential benefit: If effective, the VapeAway system could substantially raise short-term quit rates for adults who vape by combining gradual nicotine reduction with behavioral support.

How similar studies have gone: Related methods—gradual nicotine reduction and behavioral substitution combined with digital support—have shown modest success in tobacco cessation, but the specific VapeAway filter-based tapering approach is novel and not yet widely tested.
