About this study

Abstract Rationale. Electronic cigarette use is increasing at an exponential rate in Finland and internationally. The health consequences of vaporised aerosols in electronic cigarettes are largely unknown especially in a long run. Still, very few studies are available on quitting attempts with e-cigarettes as a smoking cessation tool compared to evidence based cessation pharmacotherapy in adult smokers who want to quit.

Research Objective: To investigate effectiveness and safety of e-cigarettes for smoking cessation in middle-aged smokers, and to compare the effectiveness of them to varenicline. Our study provides new information of success in smoking cessation among heavy adult smokers for clinicians.

Design: A double-blind, randomised, placebo-controlled clinical trial with the intervention phase of 12 weeks and the observational phase up to 52 weeks. This is an investigator initiated study.

Setting: Volunteer middle-aged daily smokers, who were recruited through newspaper announcements. Some of the cohort subjects were re-recruited from our previous follow-up study as many of them continued daily smoking during the whole follow-up period.

Participants: Targeted sample size of 450 adult heavy smokers, who want to quit smoking and are willing to participate up to 52 weeks´ follow-up.

Intervention and procedures: Standardized self-reported questionnaires with detailed smoking history with assessment of motivation to quit smoking, parameters of nicotine dependence, symptoms will be included. Smoking status will be repeatedly reassessed during the study visits, and self-reported smoking abstinence is verified with exhaled-carbon monoxide (CO) assessment. All adverse side effects either of drugs or of e-cigarettes, and symptoms related to the drugs or to withdrawal from smoking will be carefully reported.

This is a study with three arms. Each arm has 12 weeks intervention and observation up to 12 months:

A.Nicotine containing e-cigarettes + placebo-pills + Motivational Interview (MI)

Innokin Endura T20S + USB cable with wall adapter via USB cable (output DC5V)+ + 6x 10ml /month refill containing 18mg/ml nicotine with cigarette taste for 12 weeks.

Participants are allowed to use ad libitum e-cigarettes during 12 weeks after they have chosen the quit day during the 2nd follow-up week

Placebo -pills: starting week: 0,5mg once daily on days 1.-3 and 0,5mg twice daily on days 4.-5.Continuing weeks: 1mg twice daily up to 12 weeks

B.Nicotine-free e-cigarettes + varenicline + MI

Innokin Endura T20S + USB cable with wall adapter via USB cable (output DC5V)+ + 6x 10ml /month refill containing 0mg/ml nicotine with cigarette taste for 12 weeks Participants are allowed to use ad libitum e-cigarettes during 12 weeks after they have chosen the quit day during the 2nd follow-up week

Varenicline (Chantix®) Starting week: 0,5mg once daily on days 1.-3 and 0,5mg twice daily on days 4.-5. Continuing weeks: 1mg twice daily up to 12 weeks

C.Placebo-varenicline + nicotine -free e-cigarettes + MI Placebo -pills : starting week: 0,5mg once daily on days 1.-3 and 0,5mg twice daily on days 4.-5.Continuing weeks: 1mg twice daily up to 12 weeks

Innokin Endura T20S + USB cable with wall adapter via USB cable (output DC5V)+ 6x 10ml /month refill containing 0mg/ml nicotine with cigarette taste for 12 weeks Participants are allowed to use ad libitum e-cigarettes during 12 weeks after they have chosen the quit day during the 2nd follow-up week

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Nicotine, Varenicline Tartrate and Motivational Interview in people with Smoking Cessation and Electronic Cigarette, run by University of Oulu at 1 site in Finland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Finland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Smoking cessation during the follow-up visit at week 26 (time frame: 24 week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03235505, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 May 2024.
