E.2 Objective of the trial

E.2.1

Main objective of the trial

To assess the effects of 20 weeks of treatment with testosterone gel on fat mass as measured using full body dual X-ray absorptiometry (DEXA scan).

E.2.2

Secondary objectives of the trial

To assess the effects of 20 and 40 weeks of treatment with testosterone gel on:
1. abdominal visceral fat mass as measured using full body DEXA scan.
2. clinical parameters of adiposity, including BMI and waist circumference
3. components of the metabolic syndrome, including blood pressure en serum lipids
4. serum levels of androgens and adipocytokines
5. quality of life, sexual health, and androgen deficiency symptoms
6. testicular volume and semen quality
7. bone mass density using DEXA scan and serum bone markers
8. cellular senescence and SASP

E.2.3

Trial contains a sub-study

E.3

Principal inclusion criteria

We will include patients with metastatic testicular cancer after chemotherapy, at least 12 months after completion of last treatment and without evidence of disease. Combination chemotherapy should have contained a platinum compound, either cisplatin or carboplatin. In TC survivors, testosterone levels are routinely measured in blood during follow-up once every two years. Patients are eligible for screening if they are between 18 and 55 years of age, and have a documented low or low-normal total testosterone level ≤14 nmol/L, as measured during any of the follow-up visits, irrespective of signs and symptoms of androgen deficiency. Eligible for actual study participation and randomization between Androgel and placebo will be: survivors of TC not using testosterone supplements, having biochemical evidence of hypogonadism (defined as a serum total testosterone concentration ≤ 12 nmol/L (345 ng/dL) measured after an overnight fast between 8:00 and 10:00 AM), and being overweight (as defined by a BMI ≥ 25 and <35 kg/m2). Patients should be able to understand and abide to the study protocol and sign written informed consent.

E.4

Principal exclusion criteria

We will exclude: patients planning to father children within the next 12 months; patients already treated for hypogonadism, patients taking corticosteroids or hormone replacement other than testosterone with dose-adjustments within the last 3 months prior to randomization; patients taking medication with any antiandrogenic effects (e.g. spironolactone); patients with signs or history of hormone-dependent cancer (prostate or breast cancer); patients with severe lower urinary tract symptoms (as defined by International Prostate Symptom Score >19); patients with a history of coronary artery disease (angina pectoris, myocardial infarction) or heart failure; patients with hematocrit >50%; patients with untreated severe obstructive sleep apnea; patients with uncontrolled hypertension; patients with a BMI > 35 kg/m2; patients with a history of epilepsy; patients with debilitating psychiatric illness or inability to understand the study protocol, according to the opinion of the investigator.

E.5 End points

E.5.1

Primary end point(s)

Main endpoint is the change in fat mass (as expressed in percentage) on full body Dual-Energy X-ray Absorption (DEXA) scan after 20 weeks of treatment with testosterone gel compared with placebo.

E.5.1.1

Timepoint(s) of evaluation of this end point

After 20 weeks of treatment with testosterone gel compared with placebo.

E.5.2

Secondary end point(s)

Secondary end points are changes in the following parameters after 20 and 40 weeks of testosterone treatment compared with placebo:
• Fat mass, visceral abdominal fat and lean mass using DEXA scan
• Prevalence of the metabolic syndrome
• Resting blood pressure
• Muscle strength
• Fasting lipid levels, glucose, insulin, HOMA-index, and HbA1c
• Obesity parameters: BMI, waist circumference, waist-hip ratio, and adipocytokines measured in blood
• Bone metabolism: bone mass density using DEXA scan, and osteocalcin and vitamine D levels in blood
• Hormones of the pituitary-testicular axis
• Testicular volume and semen quality
• Quality of life, sexual health, and androgen deficiency symptoms as assessed using validated questionnaires
• Senescence-marker p16 and SASP measured in blood
• Testicular volume and semen quality
• Quality of life, sexual health, and androgen deficiency symptoms as assessed using validated questionnaires
