130Low testosterone is a condition that occurs when the body is unable to produce sufficient quantities of testosterone. The medical name for low testosterone is hypogonadism. Hypogonadism can be caused by many factors. Symptoms include: decrease in libido, lack of energy and mood swings. The goal of testosterone replacement therapy is to return testosterone levels to the normal range and relieve symptoms.
The purpose of this study is to evaluate the ability of TSX-002, which is testosterone provided in easy to swallow capsules, to maintain serum (blood) testosterone levels within the normal range in hypogonadal men. This will be determined by blood sampling at specified times during the study. The study is also intended to evaluate the tolerability of TSX-002, which will be taken orally twice per day for 15 days. In addition, the study is intended to determine a dosing regimen(s) that achieves testosterone levels within the normal range. Related Outcome Measures will be reported for Parts 1, 2, and 4.
A portion of the study (Part 3) to also assess the effect of a high-calorie, high-fat meal on the single dose pharmacokinetic exposure of TSX-002. Related outcome measures to be reported for Part 3.
TSX-002 are capsules with testosterone as the active ingredient.
Oral TSX-002 120 mg BID (total dose = 240 mg/day) for a duration of 15 days
Oral TSX-002 240 mg BID (total dose = 480 mg/day) for a duration of 15 days
Single cohort, open-label, nonrandomized oral TSX 002 120 mg BID (total dose = 240 mg/day) for a duration of 15 days
Open-label, randomized, 3-way crossover of 3 treatments, A, B, and C. Treatment A: Oral TSX-002 (1 x 120-mg capsules) administered 30 minutes after a high-calorie, high-fat meal. No food was allowed 4 hours before the high calorie, high-fat meal and no food was allowed for at least 10 hours after dosing. Treatment B: Oral TSX-002 (1 x 120-mg capsules) administered 4 hours after a high-calorie, high fat meal. No food was allowed 4 hours before the high calorie, high-fat meal and no food was allowed for at least 10 hours after dosing. Treatment C: Oral TSX-002 (1 x 120-mg capsules) administered 30 minutes before a high-calorie, high-fat meal. No food was allowed 4 hours before the high-calorie, high-fat meal and no food was allowed for at least 10 hours after dosing.
