Primary Outcome Measures:
  • Percentage of Subjects on Testosterone Treatment Achieving Target Range for Testosterone Cav (Time-averaged Concentration Over the Dosing Interval of 24 Hours) on Day 112 [ Time Frame: Day 112 ] [ Designated as safety issue: No ]
    Cav results were required to fall within the normal range of 300-1000 ng/dL. Success in the study was defined as >=75% of subjects on active treatment within the normal serum testosterone concentration range of 300-1000 ng/dL. In addition, the lower bound of the 95% CI was to be not less than 65% based on the Day 112 Parmacokinetics (PK) results


Secondary Outcome Measures:
  • Percentage of Subjects on Testosterone Treatment Achieving Target Range for Testosterone Cav (Time-averaged Concentration Over the Dosing Interval of 24 Hours) on Day 14 [ Time Frame: Day 14 ] [ Designated as safety issue: No ]
    Cav results were required to fall within the normal range of 300-1000 ng/dL at Day 14. Success was defined as >=75% of subjects on active treatment within the normal serum testosterone concentration range of 300-1000 ng/dL. In addition, the lower bound of the 95% CI was to be not less than 65% based on the Day 14 PK results

  • Percentage of Subjects on Testosterone Treatment Achieving Target Range for Testosterone Cav (Time-averaged Concentration Over the Dosing Interval of 24 Hours) on Day 56 [ Time Frame: Day 56 ] [ Designated as safety issue: No ]
    Cav results were required to fall within the normal range of 300-1000 ng/dL at Day 56. Success was defined as >=75% of subjects on active treatment within the normal serum testosterone concentration range of 300-1000 ng/dL. In addition, the lower bound of the 95% CI was to be not less than 65% based on the Day 56 PK results

  • Percentage of Subjects on Testosterone Treatment Achieving Target Range for Testosterone Cav (Time-averaged Concentration Over the Dosing Interval of 24 Hours) on Day 182 [ Time Frame: Day 182 ] [ Designated as safety issue: No ]
    Cav results were required to fall within the normal range of 300-1000 ng/dL at Day 182. Success was defined as >=75% of subjects on active treatment within the normal serum testosterone concentration range of 300-1000 ng/dL. In addition, the lower bound of the 95% CI was to be not less than 65% based on the Day 182 PK results.

  • Percentage of Subjects Achieving Target Range for Testosterone Cav During the Open-label Period at Day 266. [ Time Frame: Day 266 ] [ Designated as safety issue: No ]
    The success at Day 266 was defined as >=75% of subjects within the normal serum total testosterone concentration range of 300-1000 ng/dL. The Lower bounds of the 95% CI was to be not less than 65%.

  • Percentage of Subjects Achieving Target Range for Testosterone Cav During the Open-label Period at Day 364. [ Time Frame: Day 364 ] [ Designated as safety issue: No ]
    The success at Day 364 was defined as >=75% of subjects within the normal serum total testosterone concentration range of 300-1000 ng/dL. The Lower bounds of the 95% CI was to be not less than 65%.
