6 ADVERSE REACTIONS The most common adverse reaction (incidence greater than or equal to 3%) is skin reactions at the application site (16.1%). ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Actavis at 1-888-838-2872 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trial 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 clinical practice. In a controlled multicenter, open-label, non-comparative 90-day clinical study, 149 hypogonadal patients were treated with testosterone gel [ see Clinical Studies (14.1) ] . Adverse reactions occurred in 22.8% (34/149) of patients. The most common adverse reaction reported in this study was skin reactions associated with the site of application (16.1%; 24/149) of which 79% (19/24) were mild and the remainder were moderate (21%; 5/24) (Table 3). Table 3: Adverse Reactions Reported in >1% of Patients in the US Phase 3 Clinical Trial of Testosterone Gel Adverse Reaction Number (%) of Patients N = 149 Skin reaction 24 (16.1%) Prostatic specific antigen increased 2 (1.3%) Abnormal dreams 2 (1.3%) During the 90-day trial 5 patients (3.4%) discontinued treatment because of adverse reactions. These reactions were: 1 patient with contact dermatitis (considered probably related to testosterone gel application), 1 with application site reaction (considered probably related to testosterone gel application), 1 with gastrointestinal hypomotility (considered possibly related to testosterone gel application), 1 with severe dyspnea (considered not related to testosterone gel application), and 1 with moderate contusion (considered not related to testosterone gel application). 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of testosterone gel. Because these 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 (Table 4). Table 4: Adverse Drug Reactions from Post Approval Experience of Testosterone Gel by System Organ Class System Organ Class Adverse Reaction Blood and lymphatic system disorders Polycythemia Eye disorders Vitreous detachment Gastrointestinal disorders Abdominal symptoms General disorders and administrative site conditions Application site erythema, irritation, pruritus, and swelling; fatigue, influenza like illness, and malaise Investigations Decreased serum testosterone, increased hematocrit and hemoglobin Musculoskeletal and connective tissue disorders Pain in extremity Nervous system disorders Dizziness, headache, and migraine Reproductive system and breast disorders Erectile dysfunction and priapism Skin and subcutaneous tissue disorders Allergic dermatitis, erythema, rash, and papular rash Vascular disorders Venous thromboembolism Cardiovascular disorders Myocardial infarction and stroke 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 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 1 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 )] .

4 CONTRAINDICATIONS Testosterone gel is contraindicated in men with carcinoma of the breast or known or suspected carcinoma of the prostate [see Warnings and Precautions ( 5.1 ) and Adverse Reactions ( 6.1 )].

2 DOSAGE AND ADMINISTRATION Prior to initiating testosterone gel, confirm the diagnosis of hypogonadism by ensuring that serum testosterone concentrations have been measured in the morning on at least 2 separate days and that these serum testosterone concentrations are below the normal range. Prior to initiating testosterone gel, confirm the diagnosis of hypogonadism by ensuring that serum testosterone has been measured in the morning on at least two separate days and that these concentrations are below the normal range. ( 2 ) Starting dose of testosterone gel is 40 mg of testosterone (4 pump actuations) applied topically once daily in the morning. ( 2.1 ) Apply to clean, dry, intact skin of the thighs. Do not apply testosterone gel to the genitals or other parts of the body. (2.2 ) Dose adjustment: testosterone gel can be dose adjusted between a minimum of 10 mg of testosterone (1 pump actuation) and a maximum of 70 mg of testosterone (7 pump actuations) on the basis of total serum testosterone concentrations 2 hours post testosterone gel application. The dose should be titrated based on the serum testosterone concentration from a single blood draw 2 hours after applying testosterone gel at approximately 14 days and 35 days after starting treatment or following dose adjustment. In addition, serum testosterone concentration should be assessed periodically thereafter. ( 2.1 ) Patients should wash hands immediately with soap and water after applying testosterone gel and cover the application site with clothing after the gel has dried. Wash the application site thoroughly with soap and water prior to any situation where skin-to-skin contact of the application site with another person is anticipated. (2.2 ) Testosterone gel is not interchangeable with other topical testosterone products. ( 2.1 ) 2.1 Dosing and Dose Adjustment The recommended starting dose of testosterone gel is 40 mg of testosterone (4 pump actuations) applied once daily to the thighs in the morning. The dose can be adjusted between a minimum of 10 mg of testosterone and a maximum of 70 mg of testosterone. To ensure proper dosing, the dose should be titrated based on the serum testosterone concentration from a single blood draw 2 hours after applying testosterone gel at approximately 14 days and 35 days after starting treatment or following dose adjustment. In addition, serum testosterone concentration should be assessed periodically thereafter. Table 1 describes the dose adjustments required at each titration step. Table 1: Dose Adjustment Criteria Total Serum Testosterone Concentration 2 hours Post Testosterone Gel Application Dose Titration Equal to or greater than 2,500 ng/dL Decrease daily dose by 20 mg (2 pump actuations) Equal to or greater than 1,250 and less than 2,500 ng/dL Decrease daily dose by 10 mg (1 pump actuation) Equal to or greater than 500 and less than 1,250 ng/dL No change: continue on current dose Less than 500 ng/dL Increase daily dose by 10 mg (1 pump actuation) The application site and dose of testosterone gel are not interchangeable with other topical testosterone products. 2.2 Administration Instructions Testosterone gel should be applied directly to clean, dry, intact skin of the front and inner thighs. Do not apply testosterone gel to the genitals or other parts of the body. Patients should be instructed to use one finger to gently rub testosterone gel evenly onto the front and inner area of each thigh as directed in Table 2. Table 2: Application of Testosterone Gel Total Dose of Total Pump Pump Actuations per Thigh Testosterone Actuations Thigh #1 Thigh #2 10 mg 1 1 0 20 mg 2 1 1 30 mg 3 2 1 40 mg 4 2 2 50 mg 5 3 2 60 mg 6 3 3 70 mg 7 4 3 Once the application site is dry, the site should be covered with clothing [ see Clinical Pharmacology ( 12.3 ) ]. Wash hands thoroughly with soap and water. Avoid applying the gel to the thigh adjacent to the scrotum. Avoid fire, flames, or smoking until the gel has dried since alcohol based products, including testosterone gel, are flammable. 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 ) ]. To obtain a full first dose, it is necessary to prime the canister pump. To do so, with the canister in the upright position, slowly and fully depress the actuator eight times. The first 3 actuations may result in no discharge of gel. Safely discard the gel from the first 8 actuations. It is only necessary to prime the pump before the first dose. Strict adherence to the following precautions is advised in order to minimize the potential for secondary exposure to testosterone from testosterone gel-treated skin: Children and women should avoid contact with unwashed or unclothed application site(s) of men using testosterone gel. Testosterone gel should only be applied to the front and inner thighs (area of application should be limited to the area that will be covered by the patient’s shorts or pants). Patients should wash their hands immediately with soap and water after applying testosterone gel. Patients should cover the application site(s) with clothing (e.g., shorts of sufficient length or pants) after the gel has dried. Prior to any situation in which skin-to-skin contact with the application site 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 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.

1 INDICATIONS AND USAGE Testosterone topical gel 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 conditions such as cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, orchiectomy, Klinefelter’s syndrome, chemotherapy, or toxic damage from alcohol, heavy metals. These men usually have low serum testosterone concentrations and gonadotropins (follicle stimulating hormone [FSH] and 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 serum testosterone concentrations but have gonadotropins in the normal or low range. Limitations of Use Safety and efficacy of testosterone topical gel in men with “age-related hypogonadism” (also referred to as “late-onset hypogonadism”) have not been established. Safety and efficacy of testosterone topical gel in males less than 18 years old have not been established [ see Use in Specific Populations (8.4) ] .

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.

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

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 is a single report of acute overdosage after parenteral administration of an approved testosterone product in the literature. This subject had serum testosterone concentrations of up to 11,400 ng/dL, which were implicated in a cerebrovascular accident. There were no reports of overdose in the testosterone gel clinical trial. Treatment of overdosage would consist of discontinuation of testosterone gel, washing the application site with soap and water, and appropriate symptomatic and supportive care.

7 DRUG INTERACTIONS Androgens may decrease blood glucose and therefore may decrease insulin requirements in diabetic patients. ( 7.1 ) Changes in anticoagulant activity may be seen with androgens. More frequent monitoring of International Normalized Ratio (INR) and prothrombin time is recommended. ( 7.2 ) Use of testosterone with adrenocorticotropic hormone (ACTH) or corticosteroids may result in increased fluid retention. Use with caution, particularly in patients with cardiac, renal or hepatic disease. ( 7.3 ) 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 decrease insulin requirements. 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 anticoagulants, especially at the initiation and termination of androgen therapy. 7.3 Corticosteroids The concurrent administration of testosterone with adrenocorticotropic hormone (ACTH) or corticosteroids may result in increased fluid retention and requires careful monitoring particularly in patients with cardiac, renal, or hepatic disease.

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 the maintenance of secondary sex characteristics. These effects include the growth and maturation of the 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; 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, whereas secondary 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. 12.3 Pharmacokinetics Absorption Testosterone gel delivers physiologic amounts of testosterone, producing serum testosterone concentrations that approximate normal concentrations (greater than 300 ng/dL) seen in healthy men. Testosterone gel provides continuous transdermal delivery of testosterone for 24 hours following a single application to clean, dry, intact skin of the front and inner thighs (Figure 1). Figure 1: Mean (±SD) Serum Total Testosterone Concentrations on Day 7 in Patients Following Testosterone Gel Once-Daily Application of 40 mg of Testosterone (N=12) 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. 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% is excreted in the feces, mostly in the unconjugated form. Inactivation of testosterone occurs primarily in the liver. Potential for Testosterone Transfer The potential for testosterone transfer from healthy males dosed with testosterone gel to healthy females was evaluated in a placebo-controlled, 3-way crossover study. The washout period was approximately 29 days. Six (6) males were treated with either testosterone gel (30 mg testosterone) or placebo to 1 thigh only. At 2 hours after the application of testosterone gel to males, the females rubbed their forearms for 15 minutes on the thigh of the males. Serum concentrations of testosterone were monitored in females for 24 hours after the transfer procedure. When direct skin-to-skin transfer occurred with testosterone gel mean average concentration (C avg ) increased by 134% and mean maximum concentration (C max ) increased by 191%, compared to direct skin-to-skin transfer with placebo. When transfer occurred with testosterone gel while covering a thigh with boxer shorts, mean C avg decreased by 3% and mean C max increased by 2%, compared to direct skin-to-skin transfer with placebo [see Dosage and Administration (2.2)] . Effect of Showering In a 2-way crossover study, the effects of showering on the pharmacokinetics of total testosterone following application of testosterone gel (30 mg testosterone to each thigh; total 60 mg testosterone) were assessed in 7 hypogonadal males. There were two 7-day treatment phases, with showering 2 hours post testosterone gel application, and without showering on Day 7 of each treatment phase. Showering decreased C avg by 3% and it increased C max by 13% [ see Dosage and Administration ( 2.2 ) ]. Effect of Hand Washing and Application Site (Inner Thigh) Washing In an open-label, single-dose study, the amount of residual testosterone on the application finger and application site after washing was evaluated in 12 healthy male subjects. Prior to application of testosterone gel, each index finger and each intended application site (left and right front and inner thighs) was wiped using dry sponges to assess baseline skin testosterone. Subjects then used each index finger to rub testosterone gel (40 mg testosterone) onto each inner thigh. On one side, the index finger was immediately wiped using dry sponges to collect residual testosterone. On the other side, each subject washed their hands with liquid soap and warm tap water immediately after drug application, then wipe the index finger using dry sponges to collect residual testosterone. A mean (SD) of 0.002 (0.006) mg of residual testosterone (i.e., 99.8% reduction compared to when hand was not washed) was recovered after washing hands with liquid soap and warm tap water. Two (2) hours after the application of testosterone gel onto each inner thigh, one thigh was wiped using dry sponges. On the other thigh, the application site was washed with liquid soap and warm tap water, dried, and then wiped using dry sponges. The sponges were assayed for testosterone. A mean (SD) of 0.24 (0.009) mg of residual testosterone (i.e., 94.3% reduction compared to when application site was not washed) was recovered after application site washing.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Testosterone has been tested by subcutaneous injection and implantation in mice and rats. In mice, implant-induced cervical-uterine tumors 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.

17 PATIENT COUNSELING INFORMATION See FDA-approved Medication Guide . Patients should be informed of the following information: 17.1 Use in Men with Known or Suspected Prostate or Breast Cancer Men with known or suspected prostate or breast cancer should not use testosterone gel [see Contraindications ( 4 ) and Warnings and Precautions ( 5.1 )] . 17.2 Potential for Secondary Exposure to Testosterone and Steps to Prevent Secondary Exposure Secondary exposure to testosterone in children and women can occur with the use of testosterone gel in men. Cases of secondary exposure to testosterone in children have been reported. Physicians should advise patients of the reported signs and symptoms of secondary exposure which may include the following: In children; unexpected sexual development including inappropriate enlargement of the penis or clitoris, premature development of pubic hair, increased erections, and aggressive behavior. In women; changes in hair distribution, increase in acne, or other signs of testosterone effects. The possibility of secondary exposure to testosterone gel should be brought to the attention of a healthcare provider. Testosterone gel should be promptly discontinued until the cause of virilization is identified. Strict adherence to the following precautions is advised to minimize the potential for secondary exposure to testosterone from testosterone gel in men [see Medication Guide ] : Children and women should avoid contact with unwashed or unclothed application site(s) of men using testosterone gel. Patients using testosterone gel should apply the product as directed and strictly adhere to the following: Wash hands with soap and water after application. Cover the application site(s) with clothing after the gel has dried. Wash the application site(s) thoroughly with soap and water prior to any situation where skin-to-skin contact of the application site with another person is anticipated. In the event that unwashed or unclothed skin to which testosterone gel has been applied comes in 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 [ see Dosage and Administration ( 2.2 ), Warnings and Precautions ( 5.2 ), and Clinical Pharmacology ( 12.3 )]. 17.3 Potential Adverse Reactions with Androgens Patients should be informed that treatment with androgens may lead to adverse reactions which include: Changes in urinary habits such as increased urination at night, trouble starting your urine stream, passing urine many times during the day, having an urge that you have to go to the bathroom right away, having a urine accident, being unable to pass urine, and weak urine flow. Breathing disturbances, including those associated with sleep, or excessive daytime sleepiness. Too frequent or persistent erections of the penis. Nausea, vomiting, changes in skin color, or ankle swelling. 17.4 Patients Should Be Advised of the Following Instructions for Use Read the Medication Guide before starting testosterone gel therapy and reread it each time the prescription is renewed. Testosterone gel should be applied and used appropriately to maximize the benefits and to minimize the risk of secondary exposure in children and women. Keep testosterone gel out of the reach of children. Testosterone gel is an alcohol based product and is flammable; therefore avoid fire, flame, or smoking until the gel has dried. It is important to adhere to all recommended monitoring. Report any changes in their state of health, such as changes in urinary habits, breathing, sleep, and mood. Testosterone gel is prescribed to meet the patient’s specific needs, therefore, the patient should never share testosterone gel with anyone. Wait 2 hours before swimming or washing following application of testosterone gel. This will ensure that the greatest amount of testosterone gel is absorbed into their system.

MEDICATION GUIDE Testosterone ( tes tos' ter one ) CIII Topical Gel What is the most important information I should know about testosterone gel? 1. Testosterone gel 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 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. Children Signs and symptoms of early puberty in a child when they come in direct contact with testosterone gel 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 may include: changes in body hair. an abnormal increase in pimples (acne). Stop using testosterone gel 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 applied testosterone gel. 2. To lower the risk of transfer of testosterone gel from your body to others, follow these important instructions: Apply testosterone gel only to the front and inside area of your thighs that will be covered by clothing. Wash your hands right away with soap and water after applying testosterone gel. After the gel has dried, cover the application area with clothing. Keep the area covered until you have washed the application area well or have showered. If you expect to have skin-to-skin contact with another person, first wash the application area well with soap and water. If a child or woman touches the area where you have applied testosterone gel, that area on the child or woman should be washed well with soap and water right away. What is testosterone gel?

14 CLINICAL STUDIES 14.1 Clinical Study in Hypogonadal Males Testosterone gel was evaluated in a multicenter, 90-day open-label, non-comparative trial of 149 hypogonadal males with body mass index (BMI) greater than or equal to 22 kg/m 2 and less than 35 kg/m 2 and 18 to 75 years of age (mean age 54.5 years). The patients were screened for a single serum total testosterone concentration less than 250 ng/dL, or 2 consecutive serum total testosterone concentrations less than 300 ng/dL. Patients were caucasian (80.5%), black (10.1%), hispanic (7.4%), and other (2.0%). Testosterone gel was applied once each morning to the thighs at a starting dose of 40 mg of testosterone (4 pump actuations) per day. The dose was adjusted between a minimum of 10 mg and a maximum of 70 mg testosterone on the basis of total serum testosterone concentration obtained 2 hours post testosterone gel application on Days 14, 35, and 60 (± 3 days). The primary endpoint was the percentage of patients with C avg within the normal range (greater than or equal to 300 ng/dL and less than or equal to 1140 ng/dL) on Day 90. In patients treated with testosterone gel, 77.5% (100/129) had C avg within the normal range on Day 90. The secondary endpoint was the percentage of patients with C max above 3 pre-determined limits. The percentages of patients with C max greater than 1500 ng/dL, and between 1800 and 2499 ng/dL on Day 90 were 5.4% and 1.6%, respectively. No patient had a C max greater than or equal to 2500 ng/dL on Day 90. Dose titrations on Days 14, 35, and 60 resulted in mean (SD) C avg and C max for final doses of 10 mg to 70 mg on Day 90 shown in Table 5. Table 5: Mean (±SD) Steady-State Testosterone Concentrations (C avg and C max ) by Final Dose on Day 90 Final Dose 10mg (n=1) 20mg (n=6) 30mg (n=16) 40mg (n=30) 50mg (n=26) 60mg (n=27) 70mg (n=23 ) C avg (ng/dL) Mean 196 464 392 444 483 441 415 SD 205 164 176 156 163 136 C max (ng/dL) Mean 503 971 775 855 964 766 724 SD 399 278 417 389 292 313 Figure 2 summarizes the pharmacokinetic profiles of total testosterone in patients completing 90 days of testosterone gel treatment administered as 40 mg of testosterone once-daily for the initial 14 days followed by possible titration according to follow-up testosterone measurements. Figure 2: Mean (±SD) Steady-State Serum Total Testosterone Concentrations on Day 90 (N=129) Additionally, there were no clinically significant changes from baseline for SHBG (slight decrease), estradiol (slight increase), and ratio of DHT to total testosterone (slight increase) at Day 90.

8.5 Geriatric Use There have not been sufficient numbers of geriatric patients involved in controlled clinical studies utilizing testosterone gel to determine whether efficacy in those over 65 years of age differs from younger subjects. Of the 149 patients enrolled in the pivotal clinical study utilizing testosterone gel, 20 were over 65 years of age. Additionally, there are insufficient long-term safety data in geriatric patients to assess the potential risks of cardiovascular disease and prostate cancer. Geriatric patients treated with androgens may also be at risk for worsening of signs and symptoms of BPH.

8.4 Pediatric Use The safety and efficacy of testosterone gel in pediatric patients less than 18 years old has not been established. Improper use may result in acceleration of bone age and premature closure of epiphyses.

8.1 Pregnancy Risk Summary Testosterone gel 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 developmental 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 USE IN SPECIFIC POPULATIONS There are insufficient long-term safety data in geriatric patients using testosterone gel to assess the potential risks of cardiovascular disease and prostate cancer. ( 8.5 ) 8.1 Pregnancy Risk Summary Testosterone gel is contraindicated in pregnant women.

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 gel 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 gel, spermatogenesis may be suppressed through feedback inhibition of the hypothalamic-pituitary-testicular axis [see Warnings and Precautions (5.8)] , possibly 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 efficacy of testosterone gel in pediatric patients less than 18 years old has not been established. Improper use may result in acceleration of bone age and premature closure of epiphyses. 8.5 Geriatric Use There have not been sufficient numbers of geriatric patients involved in controlled clinical studies utilizing testosterone gel to determine whether efficacy in those over 65 years of age differs from younger subjects.
