Measured: Blood taken 15 minutes prior to T0, 2, 4, 6, 8, 10, 15, 30, 45 minutes, 1, 2, 4, 6, 9, 12, and 24 hours after T0
Area Under the Plasma Concentration-Time Curve From Time Zero (Pre-product Use) to Last Time Point [AUC(0-last)] Following Single Use of THS 2.2, CC and NRT
T0 = start of single product use.

Questions about this trial

What is this clinical trial studying?

A study testing THS 2.2, CC and NRT Gum in people with Smoking, run by Philip Morris Products S.A. at 1 site in Japan.

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 16 Jan 2025. 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 28 Jul 2015). 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?

Maximum Concentration (Cmax) of Nicotine Following Single Use of THS 2.2, CC and NRT (time frame: Blood taken 15 minutes prior to T0, 2, 4, 6, 8, 10, 15, 30, 45 minutes, 1, 2, 4, 6, 9, 12, and 24 hours after T0). The study lists 2 primary outcomes in all. 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 NCT01959607.

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 Jan 2025.
