Testosterone therapy for older men with cancer-related fatigue

Improving Cancer-related Fatigue, Sexual Dysfunction and Quality of Life in Older Men With Cancer and Androgen Deficiency

Phase 2 Interventional Seattle Institute for Biomedical and Clinical Research · NCT04301765

This study is testing if testosterone therapy can help older men with cancer feel less tired, improve their sexual function, and enhance their overall quality of life.

What this trial studies

This trial evaluates the effectiveness of testosterone replacement therapy in reducing cancer-related fatigue, improving sexual function, and enhancing quality of life in older men aged 55 and above who have solid or hematologic cancers and low testosterone levels. Participants will be randomly assigned to receive either testosterone gel or a placebo gel for six months, with multiple study visits to monitor progress. The study aims to provide insights into how testosterone therapy can alleviate symptoms associated with cancer treatment and androgen deficiency.

Who should consider this trial

Good fit: Ideal candidates are men aged 55 and older with active solid or hematologic cancers who are experiencing fatigue and have low testosterone levels.

Not a fit: Patients who are not experiencing fatigue or have normal testosterone levels may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could significantly improve the quality of life for older men suffering from cancer-related fatigue and sexual dysfunction.

How similar studies have performed: Previous studies have shown promising results with testosterone therapy in similar patient populations, indicating potential for success in this approach.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Men with active solid or hematologic (blood) cancers who have received or are receiving chemo- and/or radiation therapy. Patients who have no evidence of disease (NED) for 60 months or less, which means that they are \<60 months from their last treatment (chemotherapy and/or radiation therapy) will be included.
* Age: 55 years and older
* Life expectancy of at least 6 months.
* Serum testosterone, measured by mass spectrometry (gold standard method), of \<348 ng/dl and/or free testosterone \<70 pg/ml. The lower limits of the normal range for total testosterone in healthy men is 348 ng/dL and the lower limits of free testosterone is \<70 pg/ml in the Framingham Heart Study sample. As sex hormone binding globulin levels may be elevated in some men with cancer (resulting in elevation in total testosterone level), some of these symptomatic men may still be hypogonadal despite having total testosterone above this cut-off limit, but their free testosterone levels may still be below the lower limit of normal. Thus, men with free testosterone \<70 pg/mL will be included.
* Fatigue. Fatigue was selected as it is a highly prevalent symptom in cancer patients. Fatigue will be defined as a score on FACIT-Fatigue subscale of \<40, which best divides cancer patients from the general population with accuracy.
* Ability and willingness to provide informed consent

Exclusion Criteria:

* Men with current or prior history of prostate, breast, testicular, or adrenal cancers.
* Use of anabolic agents (testosterone, DHEA, growth hormone) within the past 6 months
* Hematocrit \>48%, serum creatinine \>2.5 mg/dL
* PSA \>4 ng/ml; nodule or induration on digital rectal exam
* Severe untreated sleep apnea
* Uncontrolled congestive heart failure
* Myocardial infarction, acute coronary syndrome, revascularization surgery, stroke or thromboembolism (of any etiology) within 6 months
* Known history of thrombophilia due to a genetic mutation (e.g. Factor V Leiden)
* Previous stroke with residual cognitive or functional deficits
* Inability to provide informed consent; MMSE score \<24
* Poorly controlled diabetes as defined by hemoglobin A1c \>10.0%
* Body mass index (BMI) \>40 kg/m2
* Bipolar disorder or schizophrenia
