    The WMS-R LM II involves a delayed paragraph recall activity scored in two components, each ranging from 0-25. The final score is the sum of each component, therefore falling in the range 0-50. WMS-R LM II scores were treated as continuous with change compared between treatment arms using linear random effects models adjusting for several factors: site, indicator variables of participation in each primary efficacy trial, baseline testosterone concentration (<200), age (≤ 75), use of anti-depressants, use of PDE-inhibitors, baseline WMSR, categorical education, and version of the WMSR.

    Values are No. (%) for dichotomous outcomes. Dichotomous hemoglobin response is an increase of 1 g/dL or more from baseline.

To test the hypothesis that testosterone treatment for one year compared to placebo will be associated with improved walking speed, improvement in sexual activity, improvement on the vitality scale and verbal memory test, and anemia correction. [ Time Frame: One year. ]

The test consists of a series of 10 primary figures, each of which has 8 corresponding secondary figures. Subjects are asked to determine which of the secondary figures is the same as the corresponding primary figure, and the score is taken as the number of figures answered correctly minus the number of figures answered incorrectly.

    Participants are required to connect a set of numbers (Part A) or alternating letters and numbers (Part B) in sequential order. The score for each part is the total time (in seconds) to complete both parts. The outcome analyzed will be the total time for Trails B minus the total time for Trails A to provide a measure of working memory, adjusted for attention and processing speed. Higher scores reflect lower executive function.

The Testosterone Trials in Older Men
Randomized, Placebo-controlled, Double-blind Study of Seven Coordinated Testosterone Treatment Trials in Older Men

The Testosterone Trials are a multi-center set of trials involving 12 clinical sites geographically distributed across the United States.

The primary specific aims are to test the hypotheses that testosterone treatment of elderly men whose serum testosterone concentrations are unequivocally low - and who have symptoms and objectively measured abnormalities in at least one of five areas that could be due to low testosterone (physical or sexual function, vitality, cognition, and anemia) - will result in more favorable changes in those abnormalities than placebo treatment.

Two additional trials have been incorporated into the T Trial. Only men enrolled in the T Trial are eligible to participate in these trials.

  • The Cardiovascular Trial will examine if testosterone treatment results in more favorable changes in cardiovascular risk factors, compared to placebo.
  • The Bone Trial will test the hypothesis that testosterone treatment will increase volumetric trabecular bone mineral density (vBMD) of the lumbar spine as measured by quantitative computed tomography (QCT), compared with placebo treatment.

A Pharmacokinetic (PK) Study is also being conducted within the context of the interventional T Trial. It will examine the variability of the serum testosterone (T) concentration after application of testosterone gel or placebo, four months after the start of treatment.

As men get older, they experience many conditions, often together, that eventually result in the inability to perform many activities of daily living, an increased propensity to fall, and decreased independence. These conditions include mobility disability and low vitality. Elderly men also experience increased anemia, metabolic syndrome, decreased sexual function and memory impairment. These conditions likely have multiple causes, but one cause that could contribute to all of them is a low serum testosterone concentration. When young hypogonadal men are treated with testosterone, they experience improvements in sexual function, muscle mass and strength, bone mineral density, sense of well being, and anemia. However, the benefits of testosterone therapy in older men with age-related decline in testosterone concentration are not known and are the subject of this investigation.

Participants will be treated with testosterone or placebo gel for 1 year. The dose will be adjusted in a blinded fashion to achieve a target T level range. Participants will be followed for one additional year following the treatment phase to assess adverse events.

  • Men participating in the Cardiovascular Trial will be assessed for changes in atherosclerotic plaque burden from 0 to 12 months.
  • Men participating in the Bone Trial will be assessed by QCT of the spine and hip, DXA of the spine and hip and clinical fractures at 0 and 12 months.
  • Men participating in the PK Study will attend 3 additional study visits for blood draws at the time of the 4-month assessment.
Interventional
Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Andropause
  • Drug: AndroGel® (testosterone gel)
    Testosterone levels will be measured at regular intervals in order to achieve a testosterone level in the desired range.
    Other Name: Testosterone gel
  • Drug: Placebo
    Testosterone levels will be measured at regular intervals.
  • Active Comparator: AndroGel® (testosterone gel)
    The initial dose of AndroGel will be 5.0 g (containing 50 mg of testosterone) once a day. Participants will apply AndroGel once daily to the shoulders, abdomen or upper arms. The serum testosterone concentration will be measured monthly for the first three months, then at months 6, 9 and 12. If the testosterone concentration is not between 500 and 800 ng/dL at any time point, the dose will be either increased by increments of 1.25-2.5 g/day, up to a maximum of 15 g/day or decreased by increments of 1.25-3.75 ng/day. Participants will be taught how to apply the gel and they will be provided with written instructions and precautions. This information will be reviewed at each contact and visit.
    Intervention: Drug: AndroGel® (testosterone gel)
  • Placebo Comparator: Placebo gel
    Placebo gel is identical to the testosterone gel and is supplied in an identical pump bottle container. It is applied to the shoulders, abdomen or upper arms once a day. Participants will be taught how to apply the gel and they will be provided with written instructions and precautions. This information will be reviewed at each contact and visit.
