Brief Summary
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.

Outcome Measures
Primary Outcomes (7)
Sexual Function Trial - Change in Psychosexual Daily Questionnaire Question 4 (PDQ-Q4) From Baseline to Month 12
Baseline score and change in responses to Question 4 of the Psychosexual Daily Questionnaire (PDQ-Q4) from baseline to Month 12. Question 4 asks 12 questions about sexual activity. Scores on the PDQ-Q4 range from 0 to 12, with higher scores indicating more activity. The change is measured form the baseline value to Month 12.
1 year (change from baseline to month 3, 6, 9 and 12)
Physical Function Trial - The 6-Minute Walk Test - no./Total no. (%)
The number and percentage of men who increased the distance walked in the 6-Minute Walk Test by at least 50 meters.
1 year (Number of participants who increased walk distance > or = 50 meters, change from baseline to month 3, 6, 9 and 12)
Vitality Trial - Increase in Functional Assessment of Chronic Illness Therapy (FACIT) - Fatigue Score Greater Than or Equal to 4 - no./Total no. (%)
The number of participants whose score on the FACIT-Fatigue scale increased by at least 4 points. Scores on the FACIT- Fatigue scale range from 0 to 52, with higher scores indicating less fatigue.
1 year (Number of participants who increased FACIT-Fatigue score > or = to 4, change from baseline to month 3, 6, 9 and 12)
Cardiovascular Trial - Assess Impact of Testosterone Treatment in Older Men on Noncalcified Plaque Volume
Non-calcified coronary artery plaque volume, mm3, as determined by coronary computed tomographic angiography (CTA), mean difference in change from baseline to month 12
1 year (change in plaque volume measurement from baseline to month 12)
Bone Trial - Volumetric Bone Mineral Density (BMD) of Spine Trabecular Bone by Quantitative Computed Tomography (QCT) in Older Men With Low Testosterone
Volumetric Bone Mineral Density (BMD) of spine trabecular bone as measured by QCT, mg/cm3, the calculated change in measurement from baseline to Month 12
1 year (QCT measurement of BMD change between baseline and month 12)
Cognitive Function Trial - Delayed Paragraph Recall Wechsler Memory Scale Revised Logical Memory II (WMS-R LMII)
Baseline score and change in score of the Wechsler Memory Scale Revised Logical Memory II (WMS-R LMII) test of Delayed Paragraph Recall, at baseline, Month 6 and Month 12. 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.
1 year (change from baseline to month 6 and month 12)
Anemia Trial - Effect of Testosterone on Hemoglobin Levels - Unexplained Anemia
Proportion of men age 65 years or older with unexplained anemia who increased their hemoglobin level by 1.0 g/dL from baseline. Values are No. (%) for dichotomous outcomes. Dichotomous hemoglobin response is an increase of 1 g/dL or more from baseline.
1 year (change in hemoglobin g/dL from baseline to month 3, 6, 9 and 12)
Secondary Outcomes (30)
Sexual Function Trial - Sexual Desire Domain
1 year (change from baseline to month 3, 6, 9 and 12)
Sexual Function Trial - Erectile Function
1 year (change from baseline to month 3, 6, 9 and 12)
Physical Function Trial - 6 Minute Walk Test - Total Walking Distance in Meters

Physical Function Trial - The Physical Function Domain (PF-10) of the SF-36 - no./Total no. (%)
1 year (change from baseline to month 3, 6, 9 and 12)
Physical Function Trial - PF 10 Overall Score
1 year (change from baseline to month 3, 6, 9 and 12)
- +25 more secondary outcomes
Study Arms (2)
AndroGel® (testosterone gel)
ACTIVE COMPARATORThe 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.
Placebo gel
PLACEBO COMPARATORPlacebo 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.
Interventions
Testosterone levels will be measured at regular intervals in order to achieve a testosterone level in the desired range.
