  • BOXED WARNING (What is this?)

    WARNING: SECONDARY EXPOSURE TO TESTOSTERONE

    • Virilization has been reported in children who were secondarily exposed to testosterone gel [see Warnings and Precautions (5.2) and Adverse Reactions (6.2)].
    • Children should avoid contact with unwashed or unclothed application sites in men using testosterone gel [see Dosage and Administration (2.2) and Warnings and Precautions (5.2)].
    • Healthcare providers should advise patients to strictly adhere to recommended instructions for use [see Dosage and Administration (2.2), Warnings and Precautions (5.2), and Patient Counseling Information (17)].
  • 1 INDICATIONS AND USAGE

    Testosterone gel 1% is indicated for testosterone replacement therapy in adult 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, orchiectomy, Klinefelter's syndrome, chemotherapy, or toxic damage from alcohol or heavy metals. These men usually have low serum testosterone concentrations and gonadotropins (follicle-stimulating hormone [FSH], luteinizing hormone [LH]) above the normal range.
    • Hypogonadotropic hypogonadism (congenital or acquired): gonadotropin or luteinizing hormone-releasing hormone (LHRH) deficiency or pituitary-hypothalamic injury from tumors, trauma, or radiation. These men have low testosterone serum concentrations but have gonadotropins in the normal or low range.

    Limitations of Use

    • Safety and efficacy of testosterone gel 1% in men with “age-related hypogonadism” (also referred to as “late-onset hypogonadism”) have not been established.
    • Safety and efficacy of testosterone gel 1% in males less than 18 years old have not been established [see Use in Specific Populations (8.4)].
    • Topical testosterone products may have different doses, strengths, or application instructions that may result in different systemic exposure [see Dosage and Administration (2) and Clinical Pharmacology (12.3)].
  • 2 DOSAGE AND ADMINISTRATION

    Prior to initiating testosterone gel 1%, confirm the diagnosis of hypogonadism by ensuring that serum testosterone concentrations have been measured in the morning on at least two separate days and that these serum testosterone concentrations are below the normal range.

    2.1 Dosing and Dose Adjustment

    The recommended starting dose of testosterone gel 1% is 50 mg of testosterone (one tube) applied once daily (preferably in the morning) to clean, dry intact skin of the shoulders and/or upper arms.

    Dose Adjustment
    To ensure proper dosing, serum testosterone concentrations should be measured. Morning, pre-dose serum testosterone concentrations should be measured approximately 14 days after initiation of therapy to ensure proper serum testosterone concentrations are achieved. If the serum testosterone concentration is below the normal range (300 ng/dL to 1,000 ng/dL), the daily testosterone gel 1% dose may be increased from 50 mg testosterone (one tube) to 100 mg testosterone (two tubes) once daily.

    The maximum recommended dose of testosterone gel 1% is 100 mg once daily.

    The application site and dose of testosterone gel 1% are not interchangeable with other topical testosterone products.

    2.2 Administration Instructions

    Upon opening the tube the entire contents should be squeezed into the palm of the hand and immediately applied to the shoulders and/or upper arms (area of application should be limited to the area that will be covered by the patient’s short sleeve T-shirt (see figure below). Do not apply testosterone gel 1% to the genitals or to the abdomen.

     figure1

    Application sites should be allowed to dry for a few minutes prior to dressing. Hands should be washed thoroughly with soap and water after testosterone gel 1% has been applied. Avoid fire, flame or smoking during the application of testosterone gel 1% until the testosterone gel 1% has dried [see Warnings and Precautions (5.2, 5.16)].

    In order to prevent transfer to another person, wear clothing to cover the application sites. If direct skin-to-skin contact with another person is anticipated, the application sites must be washed thoroughly with soap and water [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.3)].

    The patient should avoid swimming or showering or washing the administration site for a minimum of 2 hours after application [see Clinical Pharmacology (12.3)].  

     

    Strict adherence to the following precautions is advised in order to minimize the potential for secondary exposure to testosterone from testosterone-treated skin:

    • Children and women should avoid contact with unwashed or unclothed application site(s) of men using testosterone gel 1%.

    • Testosterone gel 1% should only be applied to the upper arms and shoulders. The area of application should be limited to the area that will be covered by a short sleeve T-shirt.

    • Patients should wash their hands with soap and water immediately after applying testosterone gel 1%.

    • Patients should cover the application site(s) with clothing (e.g., a T-shirt) after the gel has dried.

    • Prior to situations in which direct skin-to-skin contact is anticipated, patients should wash the application site(s) thoroughly with soap and water to remove any testosterone residue.

    • In the event that unwashed or unclothed skin to which testosterone gel 1% has been applied comes in direct contact with the skin of another person, the general area of contact on the other person should be washed with soap and water as soon as possible.

  • 3 DOSAGE FORMS AND STRENGTHS

    Testosterone gel 1% is a clear to translucent hydroalcoholic gel, for topical use and is available in a unit-dose tube. Each tube contains 50 mg testosterone in 5 g of gel.

  • 4 CONTRAINDICATIONS

    • Testosterone gel 1% is contraindicated in men with carcinoma of the breast or known or suspected carcinoma of the prostate [see Warnings and Precautions (5.1)].
    • Testosterone gel 1% is contraindicated in women who are pregnant. Testosterone can cause virilization of the female fetus when administered to a pregnant woman [see Use in Specific Populations (8.1, 8.2)].
  • 5 WARNINGS AND PRECAUTIONS

    5.1 Worsening of Benign Prostatic Hyperplasia (BPH) and Potential Risk of Prostate Cancer

    • Patients with BPH treated with androgens are at an increased risk for worsening of signs and symptoms of BPH. Monitor patients with BPH for worsening signs and symptoms.

    • Patients treated with androgens may be at increased risk for prostate cancer. Evaluate patients for prostate cancer prior to initiating and during treatment with androgens [see Contraindications (4)].

    5.2 Potential for Secondary Exposure to Testosterone

    Cases of secondary exposure resulting in virilization of children have been reported in postmarketing surveillance. Signs and symptoms have included enlargement of the penis or clitoris, development of pubic hair, increased erections and libido, aggressive behavior, and advanced bone age. In most cases, these signs and symptoms regressed with removal of the exposure to testosterone gel. In a few cases, however, enlarged genitalia did not fully return to age-appropriate normal size, and bone age remained modestly greater than chronological age. The risk of transfer was increased in some of these cases by not adhering to precautions for the appropriate use of the topical testosterone product. Children and women should avoid contact with unwashed or unclothed application sites in men using testosterone gel 1% [see Dosage and Administration (2.2), Use in Specific Populations (8.1), and Clinical Pharmacology (12.3)].

    Inappropriate changes in genital size or development of pubic hair or libido in children, or changes in body hair distribution, significant increase in acne, or other signs of virilization in adult women should be brought to the attention of a physician and the possibility of secondary exposure to testosterone gel should also be brought to the attention of a physician. Testosterone gel should be promptly discontinued until the cause of virilization has been identified.

    5.3 Polycythemia

    Increases in hematocrit, reflective of increases in red blood cell mass, may require lowering or discontinuation of testosterone. Check hematocrit prior to initiating treatment. It would also be appropriate to re-evaluate the hematocrit 3 to 6 months after starting treatment, and then annually. If hematocrit becomes elevated, stop therapy until hematocrit decreases to an acceptable concentration. An increase in red blood cell mass may increase the risk of thromboembolic events.

    5.4 Venous Thromboembolism (VTE)

    There have been postmarketing reports of venous thromboembolic events, including deep vein thrombosis (DVT) and pulmonary embolism (PE), in patients using testosterone products, such as testosterone gel 1%. Evaluate patients who report symptoms of pain, edema, warmth and erythema in the lower extremity for DVT and those who present with acute shortness of breath for PE. If a venous thromboembolic event is suspected, discontinue treatment with testosterone gel 1% and initiate appropriate workup and management [see Adverse Reactions (6.2)].

    5.5 Cardiovascular Risk

    Long term clinical safety trials have not been conducted to assess the cardiovascular outcomes of testosterone replacement therapy in men. To date, epidemiologic studies and randomized controlled trials have been inconclusive for determining the risk of major adverse cardiovascular events (MACE), such as non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death, with the use of testosterone compared to non-use. Some studies, but not all, have reported an increased risk of MACE in association with use of testosterone replacement therapy in men. Patients should be informed of this possible risk when deciding whether to use or to continue to use testosterone gel 1%.

    5.6 Abuse of Testosterone and Monitoring of Serum Testosterone Concentrations

    Testosterone has been subject to abuse, typically at doses higher than recommended for the approved indication and in combination with other anabolic androgenic steroids. Anabolic androgenic steroid abuse can lead to serious cardiovascular and psychiatric adverse reactions [see Drug Abuse and Dependence (9)].

    If testosterone abuse is suspected, check serum testosterone concentrations to ensure they are within therapeutic range. However, testosterone levels may be in the normal or subnormal range in men abusing synthetic testosterone derivatives. Counsel patients concerning the serious adverse reactions associated with abuse of testosterone and anabolic androgenic steroids. Conversely, consider the possibility of testosterone and anabolic androgenic steroid abuse in suspected patients who present with serious cardiovascular or psychiatric adverse events.

    5.7 Use in Women

    Due to lack of controlled evaluations in women and potential virilizing effects, testosterone gel 1% is not indicated for use in women [see Contraindications (4) and Use in Specific Populations (8.1, 8.2)].

    5.8 Potential for Adverse Effects on Spermatogenesis

    With large doses of exogenous androgens, including testosterone gel 1%, spermatogenesis may be suppressed through feedback inhibition of pituitary follicle-stimulating hormone (FSH) which could possibly lead to adverse effects on semen parameters including sperm count.

    5.9 Hepatic Adverse Effects

    Prolonged use of high doses of orally active 17-alpha-alkyl androgens (e.g., methyltestosterone) has been associated with serious hepatic adverse effects (peliosis hepatis, hepatic neoplasms, cholestatic hepatitis, and jaundice). Peliosis hepatis can be a life-threatening or fatal complication. Long-term therapy with intramuscular testosterone enanthate, which elevates blood levels for prolonged periods, has produced multiple hepatic adenomas. Testosterone gel 1% is not known to cause these adverse effects. Nonetheless, patients should be instructed to report any signs or symptoms of hepatic dysfunction (e.g., jaundice). If these occur, promptly discontinue testosterone gel 1% while the cause is evaluated.

    5.10 Edema

    Androgens, including testosterone gel 1%, may promote retention of sodium and water. Edema, with or without congestive heart failure, may be a serious complication in patients with preexisting cardiac, renal, or hepatic disease. In addition to discontinuation of the drug, diuretic therapy may be required.

    5.11 Gynecomastia

    Gynecomastia occasionally develops and occasionally persists in patients being treated for hypogonadism [see Adverse Reactions (6.1)].

    5.12 Sleep Apnea

    The treatment of hypogonadal men with testosterone may potentiate sleep apnea in some patients, especially those with risk factors such as obesity or chronic lung diseases.

    5.13 Lipids

    Changes in the serum lipid profile may occur. Monitor the lipid profile periodically, particularly after starting testosterone therapy and after dose increases.

    5.14 Hypercalcemia

    Androgens, including testosterone gel 1%, should be used with caution in cancer patients at risk of hypercalcemia (and associated hypercalciuria). Regular monitoring of serum calcium concentrations is recommended in these patients.

    5.15 Decreased Thyroxine-binding Globulin

    Androgens, including testosterone gel 1%, may decrease concentrations of thyroxine-binding globulins, resulting in decreased total T4 serum concentrations and increased resin uptake of T3 and T4.

    Free thyroid hormone concentrations remain unchanged, however, and there is no clinical evidence of thyroid dysfunction. 

    5.16 Flammability

    Alcohol-based products, including testosterone gel 1%, are flammable; therefore, patients should be advised to avoid fire, flame or smoking until the testosterone gel 1% has dried.

  • 6 ADVERSE REACTIONS

    6.1 Clinical Studies Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

    In a controlled clinical study, 304 patients were treated with testosterone gel 1% 50 mg or 100 mg or placebo gel for up to 90 days. Two hundred five (205) patients received testosterone gel 1% 50 mg or 100 mg daily and 99 patients received placebo. Subjects could be counted in both testosterone gel 1% treatment groups if they received both 50 mg and 100 mg at different points in the study and experienced an adverse reaction at both dose levels. Adverse reactions reported by ≥ 1% of the testosterone gel 1% patients and greater than placebo are listed in Table 1.

    The following adverse reactions occurred in fewer than 1% of patients but were greater in testosterone gel 1% groups compared to the placebo group: activated partial thromboplastin time prolonged, blood creatinine increased, prothrombin time prolonged, appetite increased, sensitive nipples, and acne.

    In this clinical trial of testosterone gel 1%, 6 patients had adverse reactions that led to their discontinuation. These events included: depression with suicidal ideation, urinary tract infection, mood swings and hypertension. No testosterone gel 1% patients discontinued due to skin reaction. In one foreign Phase 3 trial, one subject discontinued due to a skin-related adverse reaction.

    In the pivotal U.S. and European Phase 3 trials combined, at the 50-mg dosage strength, the percentage of subjects reporting clinically notable increases in hematocrit or hemoglobin were similar to placebo. However, in the 100-mg dose group, 2.3% and 2.8% of patients had a clinically notable increase in hemoglobin (≥ 19 g/dL) or hematocrit (≥ 58%), respectively, compared to 1.0% and 1.5% of patients in the placebo group, respectively.

    In the combined US and European open-label extension studies, approximately 140 patients received testosterone gel 1% for at least 6 months. The results from these studies are consistent with those reported for the US controlled clinical trial.

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during post-approval use of testosterone gel products. Because the reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

    Secondary Exposure to Testosterone in Children

    Cases of secondary exposure to testosterone resulting in virilization of children have been reported in postmarketing surveillance of testosterone gel products. Signs and symptoms of these reported cases have included enlargement of the clitoris (with surgical intervention) or of the penis, development of pubic hair, increased erections and libido, aggressive behavior, and advanced bone age. In most cases with a reported outcome, these signs and symptoms were reported to have regressed with removal of the testosterone gel exposure. In a few cases, however, enlarged genitalia did not fully return to age-appropriate normal size, and bone age remained modestly greater than chronological age. In some of the cases, direct contact with the sites of application on the skin of men using testosterone gel was reported. In at least one reported case, the reporter considered the possibility of secondary exposure from items such as the testosterone gel user’s shirts and/or other fabric, such as towels and sheets [see Warnings and Precautions (5.2)].

    Vascular Disorders

    Venous thromboembolism [see Warnings and Precautions (5.4)]

    Cardiovascular Disorders

    Myocardial infarction, stroke [see Warnings and Precautions (5.5)]

    Blood and Lymphatic Disorders

    Polycythemia [see Warnings and Precautions (5.3)]

  • 7 DRUG INTERACTIONS

    7.1 Insulin

    Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may necessitate a decrease in the dose of anti-diabetic medication.

    7.2 Oral Anticoagulants

    Changes in anticoagulant activity may be seen with androgens, therefore more frequent monitoring of international normalized ratio (INR) and prothrombin time are recommended in patients taking warfarin, especially at the initiation and termination of androgen therapy.

    7.3 Corticosteroids

    The concurrent use of testosterone with corticosteroids may result in increased fluid retention and requires careful monitoring particularly in patients with cardiac, renal or hepatic disease.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Testosterone gel 1% is contraindicated in pregnant women. Testosterone is teratogenic and may cause fetal harm based on data from animal studies and its mechanism of action [see Contraindications (4) and Clinical Pharmacology (12.1)]. Exposure of a female fetus to androgens may result in varying degrees of virilization. In animal development studies, exposure to testosterone in utero resulted in hormonal and behavioral changes in offspring and structural impairments of reproductive tissues in female and male offspring. These studies did not meet current standards for nonclinical development toxicity studies.

    Data

    Animal Data

    In developmental studies conducted in rats, rabbits, pigs, sheep, and rhesus monkeys, pregnant animals received intramuscular injection of testosterone during the period of organogenesis. Testosterone treatment at doses that were comparable to those used for testosterone replacement therapy resulted in structural impairments in both female and male offspring. Structural impairments observed in females included increased anogenital distance, phallus development, empty scrotum, no external vagina, intrauterine growth retardation, reduced ovarian reserve, and increased ovarian follicular recruitment. Structural impairments seen in male offspring included increased testicular weight, larger seminal tubular lumen diameter, and higher frequency of occluded tubule lumen. Increased pituitary weight was seen in both sexes.

    Testosterone exposure in utero also resulted in hormonal and behavioral changes in offspring. Hypertension was observed in pregnant female rats and their offspring exposed to doses approximately twice those used for testosterone replacement therapy.

    8.2 Lactation

    Risk Summary

    Testosterone is not indicated for use in females.

    8.3 Females and Males of Reproductive Potential

    Infertility

    During treatment with large doses of exogenous androgens, including testosterone, spermatogenesis may be suppressed through feedback inhibition of the hypothalamic-pituitary-testicular axis [see Warnings and Precautions (5.8)], possible leading to adverse effects on semen parameters including sperm count. Reduced fertility is observed in some men taking testosterone replacement therapy. Testicular atrophy, subfertility, and infertility have also been reported in men who abuse anabolic androgenic steroids [see Drug Abuse and Dependence (9.2)]. With either type of use, the impact on fertility may be irreversible.

    8.4 Pediatric Use

    The safety and effectiveness of testosterone gel 1% in pediatric patients less than 18 years old have not been established. Improper use may result in acceleration of bone age and premature closure of epiphyses.

    8.5 Geriatric Use

    There is insufficient long-term safety data in geriatric patients to assess the potentially increased risks of cardiovascular disease and prostate cancer [see Warnings and Precautions (5.1)].

    8.6 Renal Impairment

    No studies were conducted in patients with renal impairment.

    8.7 Hepatic Impairment

    No studies were conducted in patients with hepatic impairment.

  • 9 DRUG ABUSE AND DEPENDENCE

    9.1 Controlled Substance

    Testosterone gel 1% contains testosterone, a Schedule III controlled substance in the Controlled Substances Act.

    9.2 Abuse

    Drug abuse is intentional non-therapeutic use of a drug, even once, for its rewarding psychological and physiological effects. Abuse and misuse of testosterone are seen in male and female adults and adolescents. Testosterone, often in combination with other anabolic androgenic steroids (AAS), and not obtained by prescription through a pharmacy, may be abused by athletes and bodybuilders. There have been reports of misuse of men taking higher doses of legally obtained testosterone than prescribed and continuing testosterone despite adverse events or against medical advice.

    Abuse-Related Adverse Reactions
    Serious adverse reactions have been reported in individuals who abuse anabolic androgenic steroids, and include cardiac arrest, myocardial infarction, hypertrophic cardiomyopathy, congestive heart failure, cerebrovascular accident, hepatotoxicity, and serious psychiatric manifestations, including major depression, mania, paranoia, psychosis, delusions, hallucinations, hostility, and aggression.

    The following adverse reactions have also been reported in men: transient ischemic attacks, convulsions, hypomania, irritability, dyslipidemias, testicular atrophy, subfertility, and infertility.

    The following additional adverse reactions have been reported in women: hirsutism, virilization, deepening of voice, clitoral enlargement, breast atrophy, male-pattern baldness, and menstrual irregularities.

    The following adverse reactions have been reported in male and female adolescents: premature closure of bony epiphyses with termination of growth, and precocious puberty.

    Because these reactions are reported voluntarily from a population of uncertain size and may include abuse of other agents, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

    9.3 Dependence

    Behaviors Associated with Addiction
    Continued abuse of testosterone and other anabolic steroids, leading to addiction is characterized by the following behaviors:

    • Taking greater dosages than prescribed
    • Continued drug use despite medical and social problems due to drug use
    • Spending significant time to obtain the drug when supplies of the drug are interrupted
    • Giving a higher priority to drug use than other obligations
    • Having difficulty in discontinuing the drug despite desires and attempts to do so
    • Experiencing withdrawal symptoms upon abrupt discontinuation of use

    Physical dependence is characterized by withdrawal symptoms after abrupt drug discontinuation or a significant dose reduction of a drug. Individuals taking supratherapeutic doses of testosterone may experience withdrawal symptoms lasting for weeks or months which include depressed mood, major depression, fatigue, craving, restlessness, irritability, anorexia, insomnia, decreased libido and hypogonadotropic hypogonadism.

    Drug dependence in individuals using approved doses of testosterone for approved indications has not been documented.

  • 10 OVERDOSAGE

    There were no reports of overdose in the testosterone gel 1% clinical trials. There is a single report in the literature of acute overdosage after injection of testosterone enanthate. This subject had serum testosterone concentrations of up to 11,400 ng/dL, which were implicated in a cerebrovascular accident.

    Treatment of overdosage would consist of discontinuation of testosterone gel 1%, washing the application site with soap and water, and appropriate symptomatic and supportive care.

  • 11 DESCRIPTION

    Testosterone Gel 1% is a clear to translucent hydroalcoholic topical gel containing testosterone USP, an androgen. Testosterone Gel 1% provides continuous transdermal delivery of testosterone for 24 hours, following a single application to intact, clean, dry skin of the shoulders and/or upper arms.

    One 5-g tube of Testosterone Gel 1% contains 50 mg of testosterone, USP to be applied daily to the skin’s surface. Approximately 10% of the applied testosterone dose is absorbed across skin of average permeability during a 24-hour period.

    The active pharmacological ingredient in Testosterone Gel 1% is testosterone, USP. Testosterone, USP is a white to practically white crystalline powder chemically described as 17-β hydroxyandrost-4-en-3-one. The structural formula is shown in the following figure:

     structural formula

    Inactive ingredients in Testosterone Gel 1% are carbomer copolymer type B, carbopol 980, dehydrated alcohol (85% v/v), glycerin, pentadecalactone, polyethylene glycol 1000, propylene glycol, purified water, and tromethamine.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Endogenous androgens, including testosterone and dihydrotestosterone (DHT), are responsible for the normal growth and development of the male sex organs and for maintenance of secondary sex characteristics. These effects include the growth and maturation of prostate, seminal vesicles, penis and scrotum; the development of male hair distribution, such as facial, pubic, chest and axillary hair; laryngeal enlargement; vocal cord thickening; and alterations in body musculature and fat distribution. Testosterone and DHT are necessary for the normal development of secondary sex characteristics.

    Male hypogonadism, a clinical syndrome resulting from insufficient secretion of testosterone, has 2 main etiologies. Primary hypogonadism is caused by defects of the gonads, such as Klinefelter's syndrome or Leydig cell aplasia, while secondary hypogonadism (hypogonadotropic hypogonadism) is the failure of the hypothalamus (or pituitary) to produce sufficient gonadotropins (FSH, LH).

    12.2 Pharmacodynamics

    No specific pharmacodynamic studies were conducted using testosterone gel 1%.

    12.3 Pharmacokinetics

    Absorption
    Testosterone gel 1% delivers physiologic amounts of testosterone, producing circulating testosterone concentrations that approximate normal concentrations (e.g., 300 to 1000 ng/dL) seen in healthy men.

    The skin serves as a reservoir for the sustained release of testosterone into the systemic circulation. Approximately 10% of the testosterone applied on the skin surface is absorbed into the systemic circulation during a 24-hour period.

    Single Dose
    In single-dose studies, when either testosterone gel 1% 50 mg or 100 mg was administered, absorption of testosterone into the blood continued for the entire 24-hour dosing period. Also, mean peak and average serum concentrations within the normal range were achieved within 24 hours.

    Multiple Dose
    With single daily applications of testosterone gel 1% 50 mg and 100 mg, follow-up measurements at 30 and 90 days after starting treatment have confirmed that serum testosterone and DHT concentrations are generally maintained within the normal range.

    Figure 1 summarizes the 24-hour pharmacokinetic profile of testosterone for patients maintained on testosterone gel 1% 50 mg or testosterone gel 1% 100 mg for 30 days.

    Figure 1: Mean Steady-State Serum Testosterone (± SD) (ng/dL) Concentrations on Day 30 in Patients Applying Testosterone gel 1% Once Daily

    Figure 1

    The average daily testosterone concentration produced by testosterone gel 1% 100 mg at Day 30 was 612 (± 286) ng/dL and by testosterone gel 1% 50 mg at Day 30 was 365 (± 187) ng/dL.

    Distribution

    Circulating testosterone is primarily bound in the serum to sex hormone-binding globulin (SHBG) and albumin. Approximately 40% of testosterone in plasma is bound to SHBG, 2% remains unbound (free) and the rest is loosely bound to albumin and other proteins.

    Metabolism

    Testosterone is metabolized to various 17-keto steroids through 2 different pathways. The major active metabolites of testosterone are estradiol and DHT. The average daily DHT concentration produced by testosterone gel 1% 100 mg at Day 30 was 555 (± 293) pg/mL and by testosterone gel 1% 50 mg at Day 30 was 346 (± 212) pg/mL.

    Figure 2 summarizes the 24-hour pharmacokinetic profile of DHT for patients maintained on testosterone gel 1% 50 mg or testosterone gel 1% 100 mg for 30 days.

    Figure 2: Mean Steady-State Serum Dihydrotestosterone (± SD) (pg/mL) Concentrations on Day 30 in Patients Applying Testosterone Gel 1% Once Daily

    Figure 2

    Excretion

    There is considerable variation in the half-life of testosterone concentration as reported in the literature, ranging from 10 to 100 minutes. About 90% of a dose of testosterone given intramuscularly is excreted in the urine as glucuronic acid and sulfuric acid conjugates of testosterone and its metabolites. About 6% of a dose is excreted in the feces, mostly in the unconjugated form. Inactivation of testosterone occurs primarily in the liver.

    Potential for Testosterone Transfer from Male Patients to Female Partners

    The potential for dermal testosterone transfer following testosterone gel 1% use was evaluated in two clinical trials with males dosed with testosterone gel 1% and their untreated female partners.

    In the first trial, 30 couples were evenly randomized to 5 groups. In the first 4 groups, 100 mg of testosterone gel 1% was applied to the male abdomen and the couples were then asked to rub abdomen-to-abdomen for 15 minutes at 1 hour, 4 hours, 8 hours, or 12 hours after dose application, respectively. In these couples, serum testosterone concentrations in female partners increased from baseline by at least 6 times and potential for transfer was seen at all time points.

    When 6 males used a shirt to cover the abdomen at 15 minutes post-application and partners again rubbed abdomens for 15 minutes at the 1-hour time point, serum testosterone concentrations in female partners increased from baseline by approximately 3 times.

    In the second trial, 24 couples were evenly randomized to 4 groups. Testosterone gel 1% 100 mg was applied to the male upper arms and shoulders. In one group, 15 minutes of direct skin-to-skin rubbing began at 4 hours after application. In these 6 women, all of whom showered immediately after the rubbing activity, mean maximum serum testosterone concentrations increased from baseline by approximately 4 times. When males wore a long-sleeved T-shirt and rubbing was started at 1 and at 4 hours after application, the transfer of testosterone from male to female partners was prevented.

    Effect of Showering

    The effect of showering (with mild soap) at 1, 2, and 6 hours post application of testosterone gel 1% 100 mg was evaluated in a clinical trial in 12 men. The study demonstrated that the overall effect of washing was to decrease testosterone concentrations; however, when washing occurred 2 or more hours post drug application, serum testosterone concentrations remained within the normal range.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis
    Testosterone has been tested by subcutaneous injection and implantation in mice and rats. In mice, the implant induced cervical-uterine tumors, which metastasized in some cases. There is suggestive evidence that injection of testosterone into some strains of female mice increases their susceptibility to hepatoma. Testosterone is also known to increase the number of tumors and decrease the degree of differentiation of chemically induced carcinomas of the liver in rats.

    Mutagenesis
    Testosterone was negative in the in vitro Ames and in the in vivo mouse micronucleus assays.  

    Impairment of Fertility
    The administration of exogenous testosterone has been reported to suppress spermatogenesis in the rat, dog, and non-human primates, which was reversible on cessation of the treatment.

     

  • 14 CLINICAL STUDIES

    14.1 Clinical Trials in Adult Hypogonadal Males

    Testosterone gel 1% was evaluated in a randomized multicenter, multi-dose, active and placebo controlled 90-day study in 406 adult males with morning testosterone concentrations ≤ 300 ng/dL. The study was double-blind for the doses of testosterone gel 1% and placebo, but open-label for the non-scrotal testosterone transdermal system. During the first 60 days, patients were evenly randomized to testosterone gel 1% 50 mg, testosterone gel 1% 100 mg, placebo gel, or testosterone transdermal system. At Day 60, patients receiving testosterone gel 1% were maintained at the same dose, or were titrated up or down within their treatment group, based on 24-hour averaged serum testosterone concentration obtained on Day 30.

    Of 192 hypogonadal men who were appropriately titrated with testosterone gel 1% and who had sufficient data for analysis, 74% achieved an average serum testosterone concentration within the normal range (300 to 1,000 ng/dL) on treatment Day 90.

    Table 2 summarizes the mean testosterone concentrations on Day 30 for patients receiving testosterone gel 1% 50 mg or 100 mg.

    What is the most important information I should know about testosterone gel 1%?

    1. Testosterone gel 1% can transfer from your body to others including, children and women. Children and women should avoid contact with the unwashed or not covered (unclothed) areas where testosterone gel 1% has been applied to your skin. Early signs and symptoms of puberty have occurred in young children who have come in direct contact with testosterone by touching areas where men have used testosterone gel 1%.

      Children

      Signs and symptoms of early puberty in a child when they come in direct contact with testosterone gel 1% may include:

      Abnormal sexual changes:

      • enlarged penis or clitoris.
      • early growth of hair near the vagina or around the penis (pubic hair).
      • erections or acting out sexual urges (sex drive).

      Behavior problems:

      • acting aggressively, behaving in an angry or violent way.

      Women

      Signs and symptoms in women when they come in direct contact with testosterone gel 1%
      may include:

      • changes in body hair.
      • an abnormal increase in pimples (acne).

      Stop using testosterone gel 1% and call your healthcare provider right away if you see any signs and symptoms in a child or a woman that may have happened through accidental touching of the area where you have placed testosterone gel 1%.
