Period 3: Two Times Daily Dosing 180 mg

Period 3: Three Times Daily Dosing 120 mg

Arm Description

Period 1: Each study subject will receive an escalating single dose of TSX-002 (60, 90, 120, 180, 240 mg), with a minimum 3 day wash-out between each of the 5 escalating doses. After completing the 240 mg dose, a 7 day wash-out period will occur prior to Period 2.

Period 2: Each study subject dose is 90 mg twice daily of TSX-002, fasted for 17 days.

Period 2: Each study subject dose is 90 mg twice daily of TSX-002, fasted for 17 days. On Day 15, a serum Testosterone level will be drawn and used to dose titrate and randomized to BID or TID (as eligible). The TSX-002 dose will be down or up titrated. Period 3: Begins Day 18 with the first adjusted TSX-002 dose administered fasted two times daily. The Testosterone level on Day 22 will be used to perform the final, TSX-002 dose adjustment.

Period 2: Each study subject dose is 90 mg twice daily of TSX-002, fasted for 17 days. On Day 15, a serum Testosterone level will be drawn and used to dose titrate and randomized to BID or TID (as eligible). The TSX-002 dose will be down or up titrated. Period 3: Begins Day 18 with the first adjusted TSX-002 dose administered fasted three times daily. The Testosterone level on Day 22 will be used to perform the final, TSX-002 dose adjustment.

5. Study Description

Brief Summary
Low 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.
Detailed Description
The purpose of this study is to evaluate the pharmacokinetic (PK) parameters of testosterone after administration of TSX-002 (easy to swallow testosterone capsules) to hypogonadal men. This will be determined by blood sampling at specified times during the study. The study is also intended to evaluate the PK parameters of the testosterone metabolite, dihydrotestosterone (DHT), as well as the safety and tolerability of TSX-002. The study consists of three (3) periods, for which TSX-002 will be taken orally at various doses. Study duration is approximately 9 weeks.
