结局指标

主要结局

Area Under the Curve From Time 0 to Infinity (AUC0-inf) of Islatravir (ISL) in Plasma

时间窗: Pre-dose, 0.25, 0.5, 1, 2, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, and 168 hours post-dose

Participants were treated with ISL, and blood samples were collected from pre-dose up to 168 hours post-dose to determine the concentration of plasma ISL. The 95% confidence interval was derived from a fixed effects model performed on natural log-transformed values.

Area Under the Curve From Time 0 to Last Sampling Time (AUC0-last) of ISL in Plasma

时间窗: Pre-dose and 0.25, 0.5, 1, 2, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, and 168 hours post-dose

Participants were treated with ISL, and blood samples were collected from pre-dose up to 168 hours post-dose to determine the concentration of plasma ISL. The 95% confidence interval was derived from a fixed effects model performed on natural log-transformed values.

Maximum Concentration (Cmax) of ISL in Plasma

时间窗: Pre-dose and 0.25, 0.5, 1, 2, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, and 168 hours post-dose

Participants were treated with ISL, and blood samples were collected from pre-dose up to 168 hours post-dose to determine the concentration of plasma ISL. The 95% confidence interval was derived from a fixed effects model performed on natural log-transformed values.

时间窗: Pre-dose and 0.25, 0.5, 1, 2, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, and 168 hours post-dose

Participants were treated with ISL, and blood samples were collected from pre-dose up to 168 hours post-dose to determine the concentration of plasma ISL. The Tmax of plasma ISL was expressed as a median.

Participants were treated with ISL, and blood samples were collected from pre-dose up to 168 hours post-dose to determine the concentration of plasma ISL. The Geometric Coefficient of Variation was expressed as a percent (%CV), and is calculated from the square root of corresponding estimated variance obtained for each population in fixed effect model multiplied by 100.

Apparent Volume of Distribution During Terminal Phase (Vz/F) of ISL in Plasma

时间窗: Pre-dose and 0.25, 0.5, 1, 2, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, and 168 hours post-dose
