What is the purpose of this trial?

This trial explores whether a testosterone drug can reduce fatigue and improve the quality of life in young male cancer survivors with low testosterone levels. Participants will receive either the testosterone treatment (Testosterone Undecanoate) or a placebo for comparison. Men who have been cancer-free for at least a year, have low testosterone, and experience ongoing tiredness may be suitable candidates for this trial. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you've used anabolic agents, appetite stimulants, or systemic glucocorticoids in the past 6 months.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that testosterone undecanoate is generally safe for men with low testosterone. Some studies have found a small increase in hemoglobin, a protein in red blood cells, as a potential side effect. This effect is usually mild.

The FDA has already approved testosterone undecanoate for other uses, indicating it has passed safety checks for those conditions. This approval can offer some reassurance about its safety. However, individual reactions may vary, so discussing possible side effects with a healthcare provider is always advisable. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about testosterone undecanoate for treating fatigue in male cancer survivors because it directly addresses low testosterone levels, a common cause of fatigue in this group. Unlike other treatments that might target fatigue with lifestyle changes or antidepressants, testosterone undecanoate provides a hormonal boost, potentially offering more direct relief of symptoms. Its injectable form ensures consistent delivery and absorption, which can lead to more stable and predictable outcomes compared to other administration methods.

What evidence suggests that testosterone treatment might be effective for fatigue in male cancer survivors?

This trial will compare testosterone undecanoate with a placebo to assess its effects on fatigue in male cancer survivors. Studies have shown that testosterone replacement therapy can help reduce tiredness in men with low testosterone. Specifically, long-term use of testosterone undecanoate has been linked to significantly lower fatigue levels. This suggests that testosterone therapy might boost energy in male cancer survivors experiencing fatigue. However, some research indicates that testosterone therapy doesn't always improve quality of life or reduce tiredness for all cancer patients. These mixed results are important to consider when deciding to join the trial. ^{1 2 4 6 7}

In a study of 54 testicular cancer survivors conducted 12 months post-treatment, 33% were found to have biochemical hypogonadism, indicating a significant prevalence of testosterone deficiency in this population.

Despite the high rates of testosterone deficiency, the study found no significant link between testosterone levels and quality of life, suggesting that low testosterone may not directly impact overall well-being in these patients.

Testosterone replacement therapy (TRT) may be safe for men with confirmed androgen deficiency who have either been treated for prostate cancer or have no history of the disease, according to emerging evidence.

However, there is a significant lack of high-quality evidence (level 1 studies) to fully support TRT in men with untreated prostate cancer, leading to potential safety concerns for this group.

In a study of 176 young male cancer survivors, 13.6% were found to have significantly low total testosterone levels, which were associated with increased fat mass and higher insulin levels compared to 213 healthy controls.

The findings suggest that testosterone replacement therapy could potentially improve body composition, sexual function, and overall quality of life in these cancer survivors, highlighting the need for further interventional studies.

Injectable testosterone undecanoate (Nebido) effectively maintains stable testosterone levels in hypogonadal patients, requiring only 4-5 injections per year compared to 16 for conventional testosterone treatments, making it a more convenient option.

In hypogonadal patients with erectile dysfunction, 58% showed improvement with testosterone undecanoate, particularly benefiting diabetic patients, indicating its efficacy in this specific population.

In a 6-month double-blind trial involving 136 young male cancer survivors with low-normal testosterone levels, testosterone replacement therapy significantly reduced trunk fat mass by 0.9 kg and whole-body fat mass by 1.8 kg, while increasing lean body mass by 1.5 kg.

Despite improvements in body composition, testosterone treatment did not show any significant effects on quality of life scores, indicating that while physical changes occurred, they did not translate into perceived improvements in overall well-being.

In a study involving 24 cancer patients, testosterone therapy did not significantly reduce cancer-related fatigue (CRF) symptoms or improve inflammatory markers compared to placebo.

Despite previous findings that testosterone preserved lean body mass, this treatment did not enhance health-related quality of life or functional performance in late-stage cancer patients.

In a randomized, double-blind, placebo-controlled trial involving 29 hypogonadal males with advanced cancer, testosterone replacement did not show a significant improvement in fatigue scores after 29 days, indicating limited immediate efficacy for this symptom.

However, by day 72, testosterone treatment was associated with significant improvements in sexual desire and performance status, suggesting potential longer-term benefits that warrant further investigation in larger studies.

Nebido (undecanoate) significantly improves libido and erectile function in men with hypogonadism, as well as alleviating symptoms of chronic pelvic pain and reducing body fat in those with metabolic syndrome, based on studies involving 20 to 170 participants.

While Nebido is generally safe, it can cause a clinically significant rise in PSA levels in some patients, necessitating careful monitoring and potential discontinuation of treatment, especially in reproductively active men due to its suppression of spermatogenesis.

In a study of seven men who underwent orchidectomy for testicular cancer, intramuscular testosterone injections led to a significant drop in plasma testosterone levels, with levels falling below the normal range before the next injection.

Despite fluctuations in testosterone levels, sexual functioning was not directly affected; however, some patients reported psychological and physical side effects, such as loss of libido and mood changes, particularly towards the end of the injection interval.

Young male cancer survivors report significantly lower quality of life, energy levels, and sexual functioning compared to healthy controls, with these impairments being more pronounced in those with androgen deficiency (low testosterone levels).

Despite the observed impairments, psychological distress and self-esteem levels were normal among cancer survivors, indicating that the relationship between testosterone levels and quality of life is complex and may require further investigation through interventional trials.

Testosterone undecanoate (TU) is a long-acting injectable testosterone replacement therapy that can be administered only four times a year, providing stable testosterone levels with an excellent safety profile.
