About this study

Official title: A Randomized, Controlled, Multi-center Study to Demonstrate Reductions in Exposure to Selected Smoke Constituents in Smokers Switching to THS 2.2 Menthol or Smoking Abstinence Compared to Smoking Menthol Conventional Cigarettes, for 90 Days

The main goal of the study is to evaluate if the ad libitum use of the THS 2.2 Menthol (mTHS 2.2) for 5 days in confinement and after 85 days of product use in an ambulatory setting, by Japanese adult healthy smokers results in a reduction in the levels of biomarkers of exposure for selected harmful and potentially harmful smoke constituents (HPHCs) compared to smokers continuing smoking their own preferred brand of menthol conventional cigarette (mCC) and smoking abstinence (SA). Smokers who remained abstinent from SA were used as a benchmark to provide context to the exposure reduction.

What is being measured

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

  1. Concentration of Monohydroxybutenyl Mercapturic Acid (MHBMA)

    Concentrations measured at Day 5 in urine, adjusted for creatinine.

    Geometric Least Squares (LS) means are provided as descriptive statistics.

    Measured: 5 days

  2. Concentration of 3-hydroxypropylmercapturic Acid (3-HPMA)

    Concentrations measured at Day 5 in urine, adjusted for creatinine.

    Geometric Least Squares (LS) means are provided as descriptive statistics.

    Measured: 5 days

  3. Concentration of S-phenylmercapturic Acid (S-PMA)

    Concentrations measured at Day 5 in urine, adjusted for creatinine.

    Geometric Least Squares (LS) means are provided as descriptive statistics.

    Measured: 5 days

  4. Levels of Carboxyhemoglobin (COHb)

    % COHb blood measurements performed in the evening of Day 5, expressed as % of saturation of hemoglobin.

    Geometric Least Squares means are provided as descriptive statistics.

    Measured: 5 days

  5. Concentration of Total 4-(Methylnitrosamino)-1-(3- Pyridyl)-1-butanol) (Total NNAL)

    Concentrations measured at Day 90 in urine, adjusted for creatinine.

    Geometric Least Squares (LS) means are provided as descriptive statistics.

    Measured: 90 days

The record says: finished, as of the sponsor's last update on 23 Mar 2020. 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 Japan. 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?

Yes. Results are posted in the registry (first posted 7 Feb 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Concentration of Monohydroxybutenyl Mercapturic Acid (MHBMA) (time frame: 5 days). The study lists 5 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 23 Mar 2020.
