Brief Summary

This phase IV trial studies the effects of testosterone replacement therapy (TRT) on treatment outcomes in hypogonadal men with prostate cancer that has not spread to other parts of the body (localized) and who are on active surveillance (AS). AS in prostate cancer involves closely watching the patient's condition through regular physical exams and blood tests, but not giving treatment unless there are changes in test results. It can be a practical alternative to treatment in localized prostate cancer. Hypogonadal men have low testosterone associated with symptoms such as low libido and erectile problems. TRT can be used to treat hypogonadism by increasing testosterone levels, which may improve associated symptoms. TRT is often not used in men with prostate cancer due to concerns it may lead to the cancer growing or spreading. This may lead hypogonadal men to have a poor quality of life or to discontinue AS. TRT may improve treatment and quality of life outcomes in hypogonadal men with localized prostate cancer on active surveillance.

Outcome Measures

Primary Outcomes (4)

  • Gleason grade progression

    The Gleason grade progression will be summarized by group using standard Kaplan-Meier methods, where estimates of the median or specified rates will be obtained. Comparisons will be made between groups using the log-rank test. As exploratory analyses, Cox regression models may be considered to adjust for relevant demographic or clinical confounders. The Bonferroni method will be used to control the family-wise error rate at 0.10.

    From start of active surveillance until any progression in primary, secondary, or a combination of Gleason grades, definitive treatment, or last follow-up, assessed up to 5 years

  • Discontinuation of active surveillance

    The discontinuation of active surveillance will be summarized by group using standard Kaplan-Meier methods, where estimates of the median or specified rates will be obtained. Comparisons will be made between groups using the log-rank test. As exploratory analyses, Cox regression models may be considered to adjust for relevant demographic or clinical confounders. The Bonferroni method will be used to control the family-wise error rate at 0.10.

    From start of active surveillance until discontinuation of active surveillance due to any cause or last follow-up, assessed up to 5 years

  • International Prostate Symptom Score (Quality-of-life)

    Will be modeled as a function of group, timepoint, their two-way interaction, and a random subject effect using linear mixed models. Tests about the appropriate contrasts of model estimates will be used to compare mean changes in quality of life between groups at specified timepoints. All model assumptions will be verified graphically, and transformations applied as appropriate. As exploratory analyses, additional models may be considered to adjust for relevant demographic or clinical confounders. The Bonferroni method will be used to control the family-wise error rate at 0.10.

    Up to 5 years

  • Sexual Health Inventory for Men score (Quality-of-life)

    Will be modeled as a function of group, timepoint, their two-way interaction, and a random subject effect using linear mixed models. Tests about the appropriate contrasts of model estimates will be used to compare mean changes in quality of life between groups at specified timepoints. All model assumptions will be verified graphically, and transformations applied as appropriate. As exploratory analyses, additional models may be considered to adjust for relevant demographic or clinical confounders. The Bonferroni method will be used to control the family-wise error rate at 0.10.

    Up to 5 years

Secondary Outcomes (5)

  • Radiographic progression

    From start of active surveillance until radiographic progression, definitive treatment, or last follow-up, assessed up to 5 years

  • Biochemical progression

    From the start of active surveillance until prostate specific antigen (PSA) progression, definitive treatment, or last follow-up, assessed up to 5 years

  • Incidence of testosterone replacement therapy (TRT)-related adverse events

    Up to 5 years

  • Incidence of TRT-related complications

    Up to 5 years

  • TRT discontinuation

    Up to 5 years

Study Arms (3)

Group 1 (AS)

ACTIVE COMPARATOR

Patients with normal testosterone level undergo standard AS for up to 5 years in the absence of disease progression. Patients undergo blood sample collection and MRI throughout the trial and may undergo prostate biopsy on study.

Procedure: Biopsy of ProstateProcedure: Biospecimen CollectionProcedure: Magnetic Resonance ImagingOther: Patient ObservationOther: Questionnaire Administration

Group 2 (TRT, AS)

EXPERIMENTAL

Patients with low testosterone level associated with hypogonadal symptoms and willing to receive TRT receive testosterone per treating physician discretion via injection, gel, lotion, or transdermal patch and undergo standard AS for up to 5 years in the absence of disease progression or unacceptable toxicity. Patients undergo blood sample collection and MRI throughout the trial and may undergo prostate biopsy on study.

Group 3 (AS)

ACTIVE COMPARATOR

Patients with low testosterone level with no symptoms, or low testosterone level associated with hypogonadal symptoms but declined TRT undergo standard AS for up to 5 years in the absence of disease progression. Patients undergo blood sample collection and MRI throughout the trial and may undergo prostate biopsy on study.
