Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: TMTS treatment
Following a lead-in dose-proportionality phase (Days 1-2) and a site-to-site bioavailability phase (Days 2-9), subjects were dosed for efficacy analysis beginning on Day 9 at dose level B (a single 48 cm2 testosterone matrix transdermal system). Based on pharmacokinetic (PK) analysis of blood samples drawn on Day 16, on Day 22 subjects could be dose-titrated up to dose level C (one 28 cm2 plus one 48 cm2 TMTS), down to dose level A (one 28 cm2 TMTS), or remain at dose level B. Subjects at all dose levels were pooled for primary efficacy analysis on Days 29/30.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percent of Subjects With Testosterone Levels in the Normal Range.
Time Frame: Day 29/30
Testosterone serum concentration was determined on Day 29/30 and pharmacokinetic (PK) parameters including Cavg and Cmax were calculated for efficacy assessment. Acceptance was defined as at least 75% of subjects with Cavg in the normal range (>= 300 ng/dL to <= 1030 ng/dL), at least 85% of subjects with Cmax <= 1500 ng/dL, no more than 5% of subjects with Cmax between 1800 and 2500 ng/dL, and no subject with Cmax >= 2500 ng/dL.
Day 29/30
