Hypogonadism is an endocrine disorder characterized by absent or deficient testosterone levels along with signs and symptoms of androgen deficiency, including delayed development or regression of sexual characteristics, impaired sexual function and sense of well-being, depressed mood, decreased muscle strength associated with loss of muscle mass and reduced bone mineral density. AndroGel 1.62% has demonstrated its ability to increase total testosterone levels in the blood by absorption of testosterone through the skin when applied topically. This study evaluated the effect of AndroGel 1.62% on systolic blood pressure using ambulatory blood pressure monitoring in hypogonadal men who used testosterone replacement therapy. AndroGel 1.62% is a drug used for the treatment of hypogonadism, which is associated with low or no testosterone. This was an open-label study which means that both the study doctor and study participants knew what drug and what dose is being used. All participants in this study were in the same group, called a treatment arm. Adult male participants with hypogonadism were enrolled and received AndroGel 1.62%. This was a multi-center study with 190 participants enrolled (initially planned) in approximately 45 sites in the United States to yield 171 subjects in the per protocol (PP) population. A blinded sample size re-estimation (BSSR) was performed when around 70% of the planned subjects in the PP population had completed the end of treatment visit. Sample size was increased at BSSR and 246 participants were actually enrolled. Participants received daily topical gel doses of AndroGel 1.62% for approximately 16 weeks. There may have been a higher burden for participants in this study compared to standard of care. Participants attended 8 study visits during the course of the study at a hospital or clinic and received 2 study phone calls. The effect of the treatment was checked by medical assessments, blood tests (including pharmacokinetic sampling), and 24-hour blood pressure monitors. Read Less

The purpose of this study is to examine the effect of having testosterone deficiency in men with diabetes and with obesity. The study will also evaluate the effect of testosterone therapy. This will be done by comparing the changes in several body response indicators following treatment with testosterone in diabetic or obese-non diabetic men with low testosterone levels and comparing them to diabetic or obese-non diabetic men with low testosterone who are not treated with testosterone.

The purpose of this study is to evaluate whether DHT-Gel, when applied daily to the skin, can relieve the symptoms of low testosterone in men aged 55-80. These symptoms include reduced muscle strength, increase fat mass, low libido, feeling blue or moody Read Less

The purpose of this study is to assess the change in 24-hour ambulatory blood pressure monitoring (ABPM) between baseline (Day 0) and Day 120 following 4 months of testosterone therapy with Natesto. Read Less

The prevalence of obesity in Veterans is greater than in the general population, and even more so among users of the VA Health Care System. In addition, the population of obese older Veterans is rapidly increasing as more baby boomers become senior citizens. In older Veterans, obesity exacerbates the age- related decline in physical function and causes frailty which predisposes to admission to a VA chronic care facility. However, the optimal clinical approach to obesity in older adults is controversial because of the concern that weight loss therapy could be harmful by aggravating the age-related loss of muscle mass and bone mass. In fact, the MOVE (Managing Overweight/Obese Veterans) program does not have any guidelines for eligible Veterans if they are 70 or older. It is possible that the addition of testosterone replacement to lifestyle therapy will preserve muscle mass and bone mass and reverse frailty in obese older Veterans and thus prevent their loss of independence and decrease demand for VA health care services.

Single-arm, single site, open label study of the effects of parenteral testosterone followed by enzalutamide, abiraterone or castration-only therapy in men with metastatic CRPC who previously progressed on one of these forms of therapy. The study will enroll four cohorts of patients: men with metastatic CRPC who have progressed on enzalutamide (Cohort A; n=30); men with metastatic CRPC who have progressed on abiraterone acetate (Cohort B; n=30); men with metastatic CRPC who have progressed on first line castration-only therapy (Cohort C; n=30); men with metastatic CRPC with inactivating somatic or germline mutations in ≥2 of the genes TP53, PTEN, or RB1 (Cohort D; n=20).

This research study in infant males with Klinefelter syndrome (47,XXY) will learn more about the effect of testosterone on early health and development. The study is a total of three visits over 6 months with assessments of motor skills, body composition (muscle and fat), and hormone levels. This is a randomized, placebo-controlled study but all infants will receive testosterone treatment during the study period. The investigators will learn how testosterone treatment in infancy effects short term outcome measures on health and development. Read Less
