Brief Summary:

The purpose of this six-month treatment extension study is

  • to assess feasibility of a lower starting dose of SOV2012-F1 (daily dose of 400 mg [200 mg with breakfast meal and 200mg with dinner meal]) to titrate individual doses in order to further enhance drug administration.
  • To examine the blood pressure (BP) effects of Marius's oral testosterone undecanoate formulation, SOV2012-F1, using 24-hour ambulatory blood pressure monitoring (ABPM).

Condition or disease Intervention/treatment Phase
Hypogonadism, Male Drug: SOV2012-F1 Phase 3

Detailed Description:
This is the six-month treatment extension of Study MRS-TU-2019, which like Study MRS-TU-2019 (NCT03198728), is an open-label study. The MRS-TU-2019 ABPM Extension Study (MRS-TU-2019EXT; NCT04467697), will extend the participation for up to 170 MRS-TU-2019 subjects who chose to enroll into the MRS-TU-2019EXT, for a target of 135 evaluable subjects reaching the 4-month ABPM assessment
