Primary | Pharmacokinetics of Total Testosterone, Dihydrotestosterone, Free Testosterone: Time of Maximal Concentration (Tmax) | Tmax is the time at which the maximum concentration (Cmax) was attained during the 24 hour period on Day 7. | Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment | No |
Primary | Pharmacokinetics of Total Testosterone: Maximal Concentration (Cmax), Minimum Concentration (Cmin), and Average Concentration (Cavg) | 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. | Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment | No |
Primary | Pharmacokinetics of Dihydrotestosterone: Maximal Concentration (Cmax), Minimum Concentration (Cmin), and Average Concentration (Cavg) | 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. | Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment | No |
Primary | Pharmacokinetics of Free Testosterone: Maximal Concentration (Cmax), Minimum Concentration (Cmin), and Average Concentration (Cavg) | 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. | Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment | No |
Primary | Pharmacokinetics of Total Testosterone, Dihydrotestosterone, Free Testosterone: Degree of Fluctuation (DF) | Degree of fluctuation in serum concentration calculated as ((Cmax-Cmin)/Cavg) x 100%. | Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment | No |
Primary | Pharmacokinetics of Total Testosterone, Dihydrotestosterone, Free Testosterone: Area Under the Time Concentration Curve [AUC(0-24h)] | Area under the serum concentration versus time curve was calculated using the linear trapezoidal rule from time 0 to 24 hours on Day 7. | Day 7 (0, 2, 4, 8, 12, 16, 20, 24 hours) of each of the four 7 day cycles of treatment | No |
Secondary | Number of Participants With Adverse Events | A listing of adverse events is located in the Reported Adverse Events module. | Baseline through 7 days of each cycle of four treatments and follow-up (up to 38 days) | Yes |
