Study summary

This is a two-part trial assessing the effects of MENT on blood pressure. The first part of the trial is an open-label pilot study to verify the MENT gel formulation delivers appropriate drug levels. Upon confirming MENT serum levels are within the required range, clinical trial material will be produced and labeled. Consequently, the second part of the trial, the main study, will proceed approximately two months after the conclusion of the pilot study. The main study, is a randomized, double-blind, placebo-controlled study.

Study arms

  • Experimental
    1

    In the second part of the trial, subjects will apply MENT or placebo gel transdermally for 12 weeks and will have 24-hour blood pressure monitoring at baseline, Week 6 and Week 12.

    Drug: MENT or placebo

Interventions

  • DrugMENT or placebo

    A dose of 1600µg/d of MENT will be delivered daily using a gel formulation containing 8.0 mg of MENT per 1.0 mL (delivering 800µg/d). Two mLs of gel will be applied daily for four weeks in the pilot study (by 6 men) and for 12 weeks in the main trial (by 62 men).

    Time frame: 4 weeks

  2. To assess the effects of MENT on sperm concentration

    Time frame: 21 months

  3. To evaluate the safety and tolerability of MENT.
