(testosterone buccal system)
Striant® (testosterone buccal system) is designed to adhere to the gum or inner cheek. It provides a controlled and sustained release of testosterone through the buccal mucosa as the buccal system gradually hydrates. Insertion of Striant® twice a day, in the morning and in the evening, provides continuous systemic delivery of testosterone.
Striant® is indicated for replacement therapy in males for conditions associated with a deficiency or absence of endogenous testosterone:
Primary hypogonadism (congenital or acquired) - testicular failure due to cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, orchidectomy, Klinefelter's syndrome, chemotherapy, or toxic damage from alcohol or heavy metals. These men usually have low serum testosterone levels and gonadotropins (FSH, LH) above the normal range.
Hypogonadotropic hypogonadism (congenital or acquired) -- idiopathic gonadotropin or LHRH deficiency, or pituitary hypothalamic injury from tumors, trauma, or radiation. These patients have low serum testosterone levels but have gonadotropins in the normal or low range.

Clinical Trials Related to Striant (Testosterone)
A Study of Fortigel Testosterone Gel 2% in Males With Low Testosterone [Active, not recruiting]
Low testosterone is a condition that occurs when the body is unable to produce sufficient
quantities of testosterone. The medical name for low testosterone is hypogonadism.
Hypogonadism can be caused by many factors. Symptoms include: decrease in libido, lack of
energy and mood swings. The goal of testosterone replacement therapy is to return
testosterone levels to the normal range and relieve symptoms.
The purpose of this study is to evaluate the ability of Fortigel testosterone gel 2% to
maintain serum (blood) testosterone levels within the normal range in hypogonadal men aged 18
to 75 years. This will be determined by blood sampling at specified times during the study.
The study is also intended to evaluate the tolerability of Fortigel, which will be applied to
the skin each day throughout the study period.
Exogenous Testosterone Plus Dutasteride for the Treatment of Castrate Metastatic Prostate Cancer [Recruiting]
Usually, the male hormone testosterone makes prostate cancer cells grow. Lowering
testosterone usually stops the growth of prostate cancer. However, after a period of time
without testosterone, prostate cancer cells learn to grow again.
You are able to join this trial because your prostate cancer is growing even though you have
very low levels of testosterone. Studies have shown that high doses of testosterone, in this
situation, can cause prostate cancer cells to stop growing.
The investigators did a study several years ago in which the investigators gave high doses
of testosterone to patients such as yourself. The investigators showed that giving
testosterone in this situation was safe. The investigators also showed that the
investigators could, in some cases, make the PSA go down using high-dose testosterone.
The investigators believe that they can improve this type of treatment by combining
testosterone with another drug called dutasteride. Dutasteride is another type of hormone.
It should make testosterone levels rise. The investigators believe that combination of
dutasteride and testosterone will be more a more powerful regimen against your cancer than

Influence of Administration Route of Testosterone on Male Fertility [Not yet recruiting]
Exogenously administered testosterone will override the normal negative feedback of
endogenous testosterone on the hypothalamus and pituitary. Constantly, relatively high and
constant testosterone levels will cause a drop in FSH and LH production by the pituitary.
Since FSH and LH are signalling hormones to the testes, endogenous testosterone production
and spermatogenesis will be down-regulated. It is expected that intranasal dosing in the
morning will mimic the normal physiological pattern of testosterone production thereby
avoiding negative side-effects on spermatogenesis. Trans-dermal gels give testosterone
levels more or less constant over the day and will very likely have inhibitory effects on
The main objective of this study is to show that twice daily intranasal dosing does not
have, or has a smaller inhibitory effect on spermatogenesis in comparison to transdermal
Oral Androgens in Man-4: (Short Title: Oral T-4) [Completed]
The protocol was designed to address the hypothesis that oral testosterone enanthate plus
dutasteride can suppress the secretion of LH and FSH after four weeks of administration. In
addition, we will compare the gonadotropin suppression mediated by a dose of testosterone
enanthate (400 mg twice daily) that would be expected to maintain the serum testosterone in
the normal range throughout the day, with the same dose (800 mg once daily) administered once
daily. This larger once-daily dose is expected to result in a higher peak and lower trough
by the end of the dosing interval
