Outcome Measures

Primary Outcomes (3)

• Assessment of Bioequivalence of Prototype Mini Lozenges With Nicorette Mini Lozenge by Measuring Area Under the Plasma Concentration Versus Time Curve From Time Zero to Time t (AUC [0-t])

  Bioequivalence of prototype mini lozenges with nicorette mini lozenge was assessed by measuring AUC(0-t), where t= time of the last measurable plasma concentration. AUC(0-t) was calculated using the linear trapezoidal with linear interpolation method. A linear mixed-effects model was fit to the natural log (ln)-transformed PK variable (AUC0-t), as the dependent variable, and treatment, period, and sequence as fixed effects. Participant nested within sequence was a random effect. The treatment difference and its 90% CI were exponentiated to obtain the geometric mean ratios (GMR) between the test and reference products and its 90% CI. Geometric Coefficient of variation was provided as percentage.

  0.75, 0.5, 0.25 hours predose and 0.08, 0.17, 0.33, 0.5, 0.67, 0.83, 1, 1.25, 1.5, 2, 3, 4, 6, 8 10, 14, 16, 20 and 24 hours postdose in each treatment period

• Assessment of Bioequivalence of Prototype Mini Lozenges With Nicorette Mini Lozenge by Measuring Area Under the Plasma Concentration Versus Time Curve Calculated From Time Zero to Infinity (AUC [(0-inf])

  Bioequivalence of prototype mini lozenges with nicorette mini lozenge was assessed by measuring AUC(0-inf). AUC(0-inf) = AUC0-t + (Clast/kel), where, AUC0-t= area under the plasma concentration versus time curve from time zero to time t; Clast= last observed/measured plasma concentration and kel= elimination rate constant. A linear mixed-effects model was fit to the natural log (ln)-transformed PK variable (AUC\[0-inf\]), as the dependent variable, and treatment, period, and sequence as fixed effects. Participant nested within sequence was a random effect. The treatment difference and its 90% CI were exponentiated to obtain the GMR between the test and reference products and its 90% CI. Geometric Coefficient of variation was provided as percentage.

  0.75, 0.5, 0.25 hours predose and 0.08, 0.17, 0.33, 0.5, 0.67, 0.83, 1, 1.25, 1.5, 2, 3, 4, 6, 8 10, 14, 16, 20 and 24 hours postdose in each treatment period

• Assessment of Bioequivalence of Prototype Mini Lozenges With Nicorette Mini Lozenge by Measuring Maximum Observed Plasma Nicotine Concentration (Cmax)

  Blood samples were collected at designated timepoints. Bioequivalence of prototype mini lozenges with nicorette mini lozenge was assessed by measuring Cmax that was taken directly from bioanalytical data. Geometric Coefficient of variation was provided as percentage. A linear mixed-effects model was fit to the natural log (ln)-transformed PK variable (Cmax) as the dependent variable, and treatment, period, and sequence as fixed effects. Participant nested within sequence was a random effect. The treatment difference and its 90% CI were exponentiated to obtain the GMR between the test and reference products and its 90% CI. Geometric Coefficient of variation was provided as percentage.

Secondary Outcomes (4)

• Comparison of Prototype Mini Lozenges With Nicorette Mini Lozenge by Measuring Time of Maximum Plasma Nicotine Concentration (Tmax)

  0.75, 0.5, 0.25 hours predose and 0.08, 0.17, 0.33, 0.5, 0.67, 0.83, 1, 1.25, 1.5, 2, 3, 4, 6, 8 10, 14, 16, 20 and 24 hours postdose in each treatment period

• Comparison of Prototype Mini Lozenges With Nicorette Mini Lozenge by Measuring Apparent Elimination Half-Life (t1/2)
