About this study

Background: IQOS ("I-Quit-Ordinary-Smoking,") is a type of the growing class of "heat-not-burn" (HNB) tobacco products. The effect of the acute exposure to IQOS smoke on the pulmonary function of healthy smokers has not been studied extensively.

Objectives: Evaluation of the acute effects of IQOS on pulmonary function.

Methods: Healthy non symptomatic smokers, underwent exhaled CO measurement, spirometry including flows, volumes and diffusion capacity, and measurement of their respiratory resistances at 5, 10 and 20 Hz (R5Hz, R10Hz and R20Hz) with the use of an impulse oscillometry system (IOS) before and 15 min after the use of an IQOS.

Read the detailed description

All participants underwent pulmonary function tests (PFT) (MasterScreen PFT, Jaeger, Wurzburg, Germany) and total respiratory resistances measurement with an impulse oscillometry system (IOS)( (Viasys Jaeger MasterScreen IOS system).From the basic pulmonary measurements (flows and dynamic lung volumes), Forced Expiratory Volume in 1 second (FEV1), Forced Vital Capacity (FVC), Tiffenau index (FEV1/FVC, FEV1%), Peak Expiratory Flow (PEF), Maximal Expiratory Flow (MEF) at 25%, 50%, and 75% of vital capacity, Functional Residual Capacity (FRC), Total Lung Capacity (TLC), Residual Volume (RV), Diffusion Capacity (DLCO) were measured. Each manoeuvre was repeated for at least three technically acceptable forced expiratory flow curves in order to attain the best results. Respiratory impedance at 5 Hz (Z5Hz) and respiratory resistance at 5, 10, and 20 Hz (R5Hz, R10Hz, and R20Hz, respectively), reactance at 5, 10, and 20 Hz and resonant frequency were assessed with IOS.

After smoking heated tobacco (IQOS): 5 minutes after smoking IQOS , they repeated again PFTs and IOS measurements.

Questions about this trial

What is this clinical trial studying?

A study testing IQOS in people with Heated Tobacco and Respiratory Function, run by Aristotle University Of Thessaloniki at 1 site in Greece.

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 4 inclusion and 4 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 26 Mar 2019. 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 Greece. 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?

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?

Forced Expiratory Volume in 1 second (time frame: 5 minutes after smoking IQOS). The study lists 11 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 26 Mar 2019.
