Clinical trials

The purpose of this randomized study is to demonstrate direct clinical benefit, i.e., observed benefits in how humans with COPD feel in terms of symptoms (e.g., cough frequency, shortness of breath, and other respiratory symptoms) and function (e.g., lung function, and six-minute walking test \[6MWT\]) after switching to THS compared to continuing to smoking cigarettes.

This is a randomized, controlled, open-label, 6 parallel arms study to assess reduced exposure of biomarkers of exposure (BoE) of selected HPHC in smokers switching to TP18 (a prototype heated tobacco device) or THS relative to smokers who continue smoking CIG after 5 days of confinement period, followed by 2 days of pharmacokinetic (PK) period of single use of THS/TP18 and CIG, and followed by an ambulatory period.
