About this study

Official title: Initial Cross-over Test of a Heat-not-burn Tobacco Product to Aid in Switching From Combustible to Noncombustible Nicotine in Smokers

A novel heat-not-burn tobacco product (IQOS) will be provided to smokers, compared against a (cigarette) smoking as usual period in counter-balanced order in a cross-over design. This study will examine the short-term effects of IQOS, switching from combustible to noncombustible nicotine and withdrawal-related symptoms over a two week-long "practice" period, relative to smoking as usual.

Read the detailed description

The current within-subjects crossover study aims to directly compare initial efficacy of IQOS vs (cigarette) smoking as usual on switching from tobacco cigarettes during two-week "practice" periods in smokers.

Study interventions include IQOS, a commercially available, over the counter product. The IQOS is a commercially available tobacco product that consists of a holder which contains a rechargeable battery and an electronically heated metal blade.

All procedures will take place in the Prevention and Early Detection Center (PEDC) at the UPMC Hillman Cancer Center. Participants will be assessed daily via remote CO assessment and online questionnaire throughout the entire study (WK1-WK5). At the end of a one-week baseline of normal smoking (WK1), participants will be randomized to either: 1) begin a two-week period of attempting to completely switch to exclusive IQOS use (IQOS First); or 2) continue to smoke as usual (IQOS Last; WK2-WK3), followed by a second two-week period during which they will smoke as usual or attempt to switch to IQOS (opposite of the first period; WK4-WK5).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Objective smoke exposure

    Assessed daily using a mobile carbon monoxide monitor (iCO) provided to participants. Carbon monoxide (CO) readings parts per million (ppm) will be submitted directly via email using the iCO smartphone app.

    Measured: Up to 5 weeks

  2. Self-reported smoke exposure

    Assessed daily using self-reported cigarette consumption, with values submitted via online Qualtrics survey.

    Measured: Up to 5 weeks

  3. Harm exposure - Lung function

    Lung function will be assessed using standard pulmonary function test.

    Measured: Up to 5 weeks

  4. Harm exposure - Blood pressure

    Blood pressure will be assessed using a sphygmomanometer.

    Measured: Up to 5 weeks

Secondary outcomes (2)
  1. Cigarette craving

    Cigarette craving measured daily via Qualtrics using the Questionnaire of Smoking Urges Brief version. This will be measured on a 0-100 visual analog scale. Higher scored indicate greater craving.

    Measured: Up to 5 weeks

  2. Withdrawal symptoms

    Withdrawal symptoms measured daily via Qualtrics using the Minnesota Nicotine Withdrawal Scale. This will be measured on a 0-18 scale. Higher scores indicate greater withdrawal symptoms.

    Measured: Up to 5 weeks

Questions about this trial

What is this clinical trial studying?

A study testing IQOS and Smoking as Usual in people with Smoking Behaviors, run by University of Pittsburgh at 1 site in United States.

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 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?

The record lists 1 site in United States. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

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?

Objective smoke exposure (time frame: Up to 5 weeks). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 4 Apr 2024.
