NCT07512323

Brief Summary

The purpose of this study is to increase the functional level of the elderly to thereby reduce fall risk, improve motor skills, and increase psychological well-being, as well as to assess whether the restoration of a normal testosterone level contributes to a faster recovery. The effect of testosterone is investigated as measured by physical and mental functional capacity, including cognition, in hypogonadal elderly men with a significant loss of function. The study is aimed at participants who are too weak to participate in the progressive strength training.

Outcome Measures

Primary Outcomes (1)

  • Chair-stand test

    A measure of general strength in extremities. Number of times the participant can stand up and sit down from a chair in 30 seconds. A good correlation (r=0.78) has been found with leg press and acceptable test-retest reliability (ICC=0.86). It has recently been scientifically documented that the ability among elderly persons to perform this simple test correlates with the risk of serious fall accidents

    At weeks 0, 4 and 20.

Secondary Outcomes (9)

  • Measurement of fall frequency and severity

    At weeks 0, 4 and 20.

  • Balance ability

    At weeks 0, 4 and 20.

  • Avlund's mobility scale

    At weeks 0, 4 and 20.

  • Geriatric Depression Scale (GDS)

    At weeks 0, 4 and 20.

  • Montreal Cognitive Assessment (MoCA)

    At weeks 0, 4 and 20.

  • +4 more secondary outcomes

Study Arms (2)

Placebo

NO INTERVENTION

Patients receiving placebo

Intervention

ACTIVE COMPARATOR

Patients receiving testosterone undecanoate

Drug: Nebido (Testosterone Undecanoate)

Interventions

Testosterone supplementation is given intramuscularly with 1000 mg testosterone undecanoate, which has an effect for approx. 12 weeks, but which can be repeated more frequently between the 1st and 2nd administration. The injection is thus repeated in week 6. 3 injections per trial subject are expected, i.e., in weeks 1, 6, and 16. If the participants are motivated to continue so that long-term effects can be measured, the participants will be asked in week 12 whether they wish to continue to week 52. Upon acceptance of continuation to week 52, testosterone and placebo injections are offered according to original groups in weeks 26, 36, and 46, after which testing of primary and secondary endpoints is not only performed in week 20 but also in week 52.

Masking Details
Treatment with testosterone is made double-blind. We will ensure that the persons evaluating a patient do not have knowledge of the patient's treatment group.
Purpose
TREATMENT
Intervention Model
PARALLEL
Model Details: Participants are randomized equally into 2 different treatment groups with 48 participants each: 1. A control group given 3 placebo injections 2. A testosterone group given 3 testosterone injections. Randomization is thus into two arms so that the effect of testosterone can be evaluated against placebo.
