Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are men aged 18 and older with localized prostate cancer on active surveillance and low testosterone levels.
✕Probably not a fit
Patients with advanced prostate cancer, contraindications to TRT, or those with high-risk cancer profiles may not benefit from this study.

What this trial studies
This phase IV trial investigates the effects of testosterone replacement therapy (TRT) on hypogonadal men with localized prostate cancer who are undergoing active surveillance. The study aims to assess the impact of TRT on cancer progression, quality of life, and the likelihood of discontinuing active surveillance due to adverse effects. Participants will be monitored through regular blood tests, MRI scans, and questionnaires to evaluate changes in symptoms and cancer markers over time. The trial seeks to determine if TRT can improve the quality of life for these patients without exacerbating their cancer.
Why it matters
Potential benefit: If successful, this study could enhance the quality of life for hypogonadal men with localized prostate cancer by alleviating symptoms associated with low testosterone.
How similar studies have gone: While TRT in prostate cancer patients has been approached cautiously, this study explores a novel application of TRT in a specific patient population under active surveillance.
