Reduced Exposure Study Using the CHTP 1.2 With 5 Days in a Confinement Setting Followed by 85 Days in an Ambulatory Setting.
A Randomized, Controlled, Open-label, 2-arm Parallel Group, Single Center Study to Demonstrate Reductions in Exposure to Selected Smoke Constituents in Healthy Smokers Switching to the Carbon Heated Tobacco Product 1.2 (CHTP 1.2), Compared to Continuing to Use Combustible Cigarettes, for 5 Days in Confinement Followed by 85 Days in an Ambulatory Setting.

Measure Description |
Time Frame |
|---|---|---|
|
Concentrations of Monohydroxybutenylmercapturic Acid (MHBMA)
Time Frame: 5 days
|
Concentrations measured at Day 5 in urine, adjusted for creatinine. Geometric least squares (LS) means and confidence intervals (Cls) from a generalized linear model conducted on log-transformed Day 5 values with log-transformed baseline value, study arm, sex and CC consumption reported at admission as fixed effect factors. |
5 days
|
|
Concentration of 3-hydroxypropylmercapturic Acid (3-HPMA)
Time Frame: 5 days
|
Concentrations measured at Day 5 in urine, adjusted for creatinine. Geometric least squares (LS) means and confidence intervals (Cls) from a generalized linear model conducted on log-transformed Day 5 values with log-transformed baseline value, study arm, sex and CC consumption reported at admission as fixed effect factors. |
5 days
|
|
Concentration of S-phenylmercapturic Acid (S-PMA)
Time Frame: 5 days
|
Concentrations measured at Day 5 in urine, adjusted for creatinine. Geometric least squares (LS) means and confidence intervals (Cls) from a generalized linear model conducted on log-transformed Day 5 values with log-transformed baseline value, study arm, sex and CC consumption reported at admission as fixed effect factors. |
5 days
|
|
Levels of Carboxyhemoglobin (COHb)
Time Frame: 5 days
|
% COHb blood measurements performed in the evening of Day 5, expressed as % of saturation of hemoglobin. Geometric least squares (LS) means and confidence intervals (Cls) from a generalized linear model conducted on log-transformed Day 5 values with log-transformed baseline value, study arm, sex and CC consumption reported at admission as fixed effect factors. |
5 days
|
|
Concentrations of Total 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanol (Total NNAL)
Time Frame: 90 days
|
Concentrations measured at Day 90 in urine, adjusted for creatinine. Geometric least squares (LS) means and confidence intervals (Cls) from a generalized linear model conducted on log-transformed Day 90 values with log-transformed baseline value, study arm, sex and CC consumption reported at admission as fixed effect factors. |
