结局指标
主要结局
Pharmacokinetics of Total Testosterone, Dihydrotestosterone, Free Testosterone: Time of Maximal Concentration (Tmax)
时间窗: Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment
Tmax is the time at which the maximum concentration (Cmax) was attained during the 24 hour period on Day 7.
Pharmacokinetics of Total Testosterone: Maximal Concentration (Cmax), Minimum Concentration (Cmin), and Average Concentration (Cavg)
时间窗: Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment
Cmax is the maximum observed serum concentration of total testosterone during the 24 hour period on Day 7. Cmin is the minimum observed serum concentration during the 24 hour period on Day 7. Cavg(0-24) is the average serum concentration calculated during the 24 hour period on Day 7. Calculated as the AUC(0-24) divided by 24 hours.
Pharmacokinetics of Dihydrotestosterone: Maximal Concentration (Cmax), Minimum Concentration (Cmin), and Average Concentration (Cavg)
时间窗: Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment
Cmax is the maximum observed serum concentration of dihydrotestosterone during the 24 hour period on Day 7. Cmin is the minimum observed serum concentration during the 24 hour period on Day 7. Cavg(0-24) is the average serum concentration calculated during the 24 hour period on Day 7. Calculated as the AUC(0-24) divided by 24 hours.
Pharmacokinetics of Free Testosterone: Maximal Concentration (Cmax), Minimum Concentration (Cmin), and Average Concentration (Cavg)
时间窗: Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment
Cmax is the maximum observed serum concentration of free testosterone during the 24 hour period on Day 7. Cmin is the minimum observed serum concentration during the 24 hour period on Day 7. Cavg(0-24) is the average serum concentration calculated during the 24 hour period on Day 7. Calculated as the AUC(0-24) divided by 24 hours.
Pharmacokinetics of Total Testosterone, Dihydrotestosterone, Free Testosterone: Degree of Fluctuation (DF)
时间窗: Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment
Degree of fluctuation in serum concentration calculated as ((Cmax-Cmin)/Cavg) x 100%.
Pharmacokinetics of Total Testosterone, Dihydrotestosterone, Free Testosterone: Area Under the Time Concentration Curve [AUC(0-24h)]
时间窗: Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment
Area under the serum concentration versus time curve was calculated using the linear trapezoidal rule from time 0 to 24 hours on Day 7.
