About this study
Official title: Testosterone Supplementation and Exercise in Elderly Men
The purpose of this study is to evaluate the effects of testosterone supplementation (AndroGel) on body composition, strength, endurance, cognition, and function in older men.
Read the detailed description
Studies suggest that testosterone (T) replacement in healthy elderly men has beneficial effects on body composition, muscle, bone, memory, and behavior, but the risks of chronic treatment, especially on the prostate, heart, and sleep quality, are not entirely clear. Therefore, it is most desirable to supplement into the lowest "effective" range in elderly men. However, the effects of lower than usual replacement T doses have not been well studied. Furthermore, the possible important interaction of exercise to enhance the positive effects of T supplementation, yet mitigate the possible side effects, has not been studied in older men.
This one-year study will enroll 150 men with low-normal to slightly below normal serum total T levels. Participants will be randomized into one of 6 treatment groups to receive T supplementation (AndroGel) of 25mg/day, 50 mg/day or a placebo crossed with progressive resistance training (PRT) exercise 3 times a week versus none. At the end of the study, participants in the exercise-control group will be offered PRT.

What is being measured
The primary outcome is the main question the study is designed to answer.
Physical Function (CS-PFP Total Score)
Continuous-scale physical function performance test (CS-PFP) which comprises 15 everyday tasks requiring upper and lower body strength and flexibility, balance, coordination and endurance. The CS-PFP was developed to measure performance in higher functioning adults with minimal floor or ceiling effects, and is valid, reliable and sensitive to change. Total and domain scores are scaled from 0 to 100, with higher scores indicating better function.
Measured: Baseline and 12 months
Secondary outcomes (5)
Upper Body Muscle Strength (1-RM, kg)
The maximal weight a participant could lift once (1-repetition maximum, 1-RM) was assessed at baseline and 12 months. The average of the difference from baseline in 4 upper-body 1-RM measures (bench press,incline press, overhead pull-down, and seated row) are represented.
Measured: Baseline and 12 months
Lower Body Muscle Strength (1-RM, kg)
The maximal weight a participant could lift once [1-repetition maximum, 1-RM] was assessed at baseline and 12 months. The average of the difference from baseline in 3 lower-body 1-RM measures (knee extension, knee flexion, and seated leg press)) are represented.
Measured: Baseline and 12 months
Power (Power Rig, Watts)
Leg extensor power was evaluated using a Nottingham leg extensor power rig (watts).
Measured: Baseline and 12 months
Fat Mass (kg)
Total change in Fat mass (kg) as evaluated by DXA
Measured: Baseline and 12 months
Fat Free Mass (kg)
Total change in Fat free mass (kg) as evaluated by DXA
Measured: Baseline and 12 months

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing LowT, Resistance Training and HighT in people with Healthy, run by University of Colorado, Denver at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 20 Jan 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Physical Function (CS-PFP Total Score) (time frame: Baseline and 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00112151, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2020.
