Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 22 to 55 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Prior to study start, subjects must be current smokers of conventional factory-made cigarettes (eCO >10ppm at screening) who have either tried or are occasional users of e-cigarettes. Subjects must be smoking ≥10 cigarettes per day and must have done so for at least one year. Smoking status will be confirmed with a urinary cotinine level of ≥200ng/ml (determined using NicAlert cotinine test kit) and an exhaled breath CO level of >10ppm (determined using a Smokerlyzer breath CO monitor) at screening, as well as by tobacco use questionnaire.
  • Subjects will be males or non-pregnant, non-lactating females, and between 22 and 55 years of age inclusive. Age verification will be performed by checking of Federal or state-issued ID (eg. passport or driving licence) during screening.
  • Women of child-bearing potential should be using one of the following acceptable methods of contraception : combined (oestrogen and progestogen containing) oral, intravaginal or transdermal hormonal contraception associated with inhibition of ovulation; progestogen-only hormonal contraception, either oral, injected or implanted, associated with inhibition of ovulation; progestogen-only oral hormonal contraception where inhibition of ovulation is not the primary mode of action; intrauterine device (IUD); intrauterine hormone-releasing system (IUS); bilateral tubal occlusion; male or female condom with or without spermicide; cap, diaphragm or sponge with spermicide.
  • Women of non-childbearing potential may be included if they are either surgically sterile (hysterectomy and/or oophorectomy) or postmenopausal for more than 1 year and must have a negative urine pregnancy test result during screening. Women who are surgically sterile must provide documentation of the procedure by an operative report.
  • Male subjects must use an approved method of birth control during the entire study. These subjects must not donate sperm during this time.
  • Subjects must be in good health, as judged by the PI or the appropriately qualified designee based on medical history, ECG, vital signs, blood biochemistry, haematology, urinalysis and physical examination.

For all subjects, prescribed use of blood pressure (beta blockers) and lipid lowering (statin) medications are permitted.
  • Subjects who have used any drugs or substances (except tobacco) known to be strong inducers or inhibitors of any CYP enzymes (formerly known as cytochrome P450 enzymes) within a 28 days period prior to first product administration. For a list of such drugs and substances, please refer to http://medicine.iupui.edu/clinpharm/ddis/main-table/.
  • Subjects who have had any treatment with smoking cessation medications (e.g. Bupropion, Chantix or any NRT) within 30 days of the planned first product use occasion.
  • Subjects with any other clinically significant medical history, in the Investigator's opinion, including conditions which might affect drug absorption, metabolism or excretion.
  • Female subjects, who are pregnant or become pregnant during the course of the study.
  • Subjects who have lost or donated more than 450ml of blood within the 2 months preceding the first product administration.
  • Subjects who are self-reported non-inhalers (smokers who draw smoke from the cigarette into the mouth and throat but who do not inhale). Subjects who are observed as non-inhalers at Admission by the clinic staff will be excluded.
  • Subjects who are currently trying to stop smoking or to stop using e-cigarettes, or considering stopping in the next two months. All subjects will be informed that they are free to quit smoking/using e-cigarettes and withdraw from the study at any time.

  • Subjects who in the opinion of the Principal Investigator or their appropriately qualified designee should not participate in the study for any other reason.
  • To be re-confirmed during each clinic visit:
  • Subject continues to meet all screening exclusion criteria. Pregnancy test to be performed on all female subjects at each visit.
  • Receipt of any medication since screening visit that may have an impact on the safety and objectives of the study (at the Principal Investigator's discretion).

Questions about this trial

What is this clinical trial studying?

A study testing Use electronic cigarette or smoke conventional cigarette in people with Healthy Volunteers and Smoking, run by British American Tobacco (Investments) Limited 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 12 inclusion and 22 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 7 Dec 2022. 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 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?

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?

Plasma nicotine concentration (Cmax) (time frame: -5, 1, 3, 5, 6, 7, 9, 15, 45, and 60 minutes relative to the first puff on the cigarette/e-cigarette). The study lists 3 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 7 Dec 2022.
