    Dose-Response of Gonadal Steroids and Bone Turnover in Older Men

    NCT00114114

    Sept 2004 to 1 Nov 2017

Registry summary

Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.

The purpose of this study is to determine the levels of testosterone and/or estradiol at which changes in bone turnover, body composition, strength, sexual function etc. begin to occur in older men. This information may help determine when to intervene with hormone replacement therapy in aging men.

Interventions

  • TestosteroneDrug
  • Goserelin acetateDrug

Arms6

  • Experimental

    Group 1: 0 g/day

    Zoladex plus Placebo Testosterone (T) gel

  • Experimental

    Group 2: 1.25 g/day

    Zoladex plus 1.25 g/day T gel

  • Experimental

    Group 3: 2.5 g/day

    Zoladex plus 2.5 g/day T gel

  • Experimental

    Group 4: 5 g/day

    Zoladex plus 5 g/day T gel

  • Experimental

    Group 5: 10* g/day

    Zoladex plus 10\* g/day T gel. \*Note that the 10 g/day dose was reduced to 7.5 g/day part-way through the trial

  • Experimental

    Group 6: Placebo/Placebo (PBO/PBO)

    Placebo Zoladex plus Placebo T gel (controls)

Primary outcomes1

Outcomes the sponsor listed as primary.

  1. Percent Change in Bone Turnover Marker (Serum C-telopeptide, CTX)

    Time frame · Baseline and 16 weeks

Secondary outcomes(4)
  1. Percentage Change in Body Composition: Fat Mass

    Time frame · Baseline and 16 weeks

  2. Percentage Change in Thigh Muscle Area

    Time frame · Baseline and 16 weeks

    Registry description

    Assessed by quantitative computed tomography (QCT)

  3. Change in Erectile Function Symptoms

    Time frame · Baseline and 16 weeks

    Registry description

    Based on International Index of Erectile Function (IIEF) scale, question #15, which asked subjects to rate their confidence that they could achieve and maintain an erection. Scores range from 1 to 5, with higher scores being better.

  4. Change in Libido / Sexual Desire

    Time frame · 16 weeks

    Registry description

    Change in libido from baseline (scale ranges from -2 to +2), with -2 being much less, -1 somewhat less, 0 same, +1 somewhat more, +2 much more
