A Study of the Effect of Topical Testosterone Replacement Therapy on Blood Pressure in Adult Male Participants With Hypogonadism
A Study of the Effect of Topical Testosterone Replacement Therapy on Blood Pressure in Adult Male Participants With Hypogonadism
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 will evaluate the effect of AndroGel 1.62% on systolic blood pressure
 using ambulatory blood pressure monitoring in hypogonadal men who use testosterone
 replacement therapy.

 AndroGel 1.62% is a drug used for the treatment of hypogonadism, which is associated with low
 or no testosterone. This is an open-label study which means that both the study doctor and
 study participants will know what drug and what dose is being used. All participants in this
 study will be in the same group, called a treatment arm. Adult male participants with
 hypogonadism will be enrolled and receive AndroGel 1.62%. This is a multi-center study with
 around 190 participants enrolled in approximately 45 sites in the United States.

 Participants will receive daily topical gel doses of AndroGel 1.62% for approximately 16
 weeks.

 There may be a higher burden for participants in this study compared to standard of care.
 Participants will attend 8 study visits during the course of the study at a hospital or
 clinic and receive 2 study phone calls. The effect of the treatment will be checked by
 medical assessments, blood tests (including pharmacokinetic sampling), and 24-hour blood
 pressure monitors.
Inclusion Criteria:

 -  Diagnosis of hypogonadism with the presence of at least one of the following symptoms
 that may be related to low testosterone values and is/are consistent with
 hypogonadism:

 -  Decreased sexual desire or libido

 -  Decreased spontaneous erections (e.g. morning erections)

 -  Decreased energy or fatigue/feeling tired

 -  Low mood or depressed mood

 -  Loss of body (axillary and pubic) hair or reduced shaving

 -  Hot flashes AND

 -  Confirmed by 2 serum testosterone levels < 300 ng/dL by blood samples drawn at least
 48 hours apart. These samples should be obtained between 5 am and 11 am local time.

 -  Blood pressure >100/60 mmHg and <140/90 mmHg.

 Exclusion Criteria:

 -  Unprovoked deep vein thrombosis (DVT), unprovoked pulmonary embolism (PE), or known
 thrombophilia.

 -  Polycythemia vera or secondary polycythemia, such as polycythemia due to untreated
 sleep apnea or severe chronic obstructive pulmonary disease

 -  Prostate or breast cancer

 -  Any active malignancy.

 -  Clinically significant medical conditions or any other reason that the investigator
 determines would interfere with participation in this study or would make the
 participant an unsuitable candidate to receive study drug.

 -  Work night shifts or is otherwise required to perform strenuous manual labor while
 wearing the Ambulatory Blood Pressure Monitor (ABPM).
