Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Period 1: Single Dose
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.

TSX-002 are capsules with testosterone as the active ingredient.

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

EXPERIMENTAL: Period 3: Two Times Daily Dosing 120 mg
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. |

EXPERIMENTAL: Period 3: Three Times Daily Dosing 90 mg
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. |
