ABUSE SECTION.

9.2 Abuse. Drug abuse is intentional non-therapeutic use of 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 pharmacy, may be abused by athletes and bodybuilders. There have been reports of misuse by men taking higher doses of legally obtained testosterone than prescribed and continuing testosterone despite adverse events or against medical advice.. Abuse-Related Adverse ReactionsSerious 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 population of uncertain size and may include abuse of other agents, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.

ADVERSE REACTIONS SECTION.

6 ADVERSE REACTIONS. Most common adverse reactions (incidence >= 2% of the testosterone gel patients and greater than placebo) are application site reactions and increased hematocrit. (6.1)To report SUSPECTED ADVERSE REACTIONS, contact UPSHER-SMITH LABORATORIES, LLC at 1-855-899-9180 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.. Most common adverse reactions (incidence >= 2% of the testosterone gel patients and greater than placebo) are application site reactions and increased hematocrit. (6.1). 6.1 Clinical Trial Experience. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.In controlled clinical study, 304 patients were treated with testosterone gel 50 mg or 100 mg or placebo gel for up to 90 days. Two hundred-five (205) patients received testosterone gel 50 mg or 100 mg daily and 99 patients received placebo. Subjects could be counted in both testosterone gel 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 patients and greater than placebo are listed in Table 3.Table 3: Incidence of Adverse Reactions (Reported by >=1% of the Testosterone Gel Patients and Greater than Placebo) in the Controlled Clinical Trial Through 90 DaysTestosterone Gel50 mgTestosterone Gel100 mgPlaceboEvent(n=103)(n=149)(n=99)Application Site Reactions2%4%3%Blood Pressure Increased1%1%0%Gynecomastia1%0%0%Headache1%1%0%Hematocrit/Hemoglobin Increased1%2%0%Hot Flushes1%0%0%Insomnia1%0%0%Mood Swings1%0%0%Smell Disorder1%0%0%Spontaneous Penile Erection1%0%0%Taste Disorder1%1%0%The following adverse reactions occurred in fewer than 1% of patients but were greater in testosterone gel 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, six patients had adverse events that led to their discontinuation. These events included: depression with suicidal ideation, urinary tract infection, mood swings and hypertension. No testosterone gel patients discontinued due to skin reaction. In one foreign Phase trial, one subject discontinued due to skin-related adverse event.In the pivotal U.S. and European Phase 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 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 U.S. and European open label extension studies, approximately 140 patients received testosterone gel for at least months. The results from these studies are consistent with those reported for the U.S. 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 population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.. Secondary Exposure to Testosterone in ChildrenCases 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 reported outcome, these signs and symptoms were reported to have regressed with removal of the testosterone gel exposure. In 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 texts such as the testosterone gel users shirts and/or other fabrics, such as towels and sheets [see Warnings and Precautions (5.2)].. Cardiovascular Disorders:Myocardial infarction, stroke [see Warnings and Precautions (5.5)] Vascular Disorders:Venous thromboembolism [see Warnings and Precautions (5.4)].

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. CarcinogenicityTestosterone 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.. MutagenesisTestosterone was negative in the in vitro Ames and in the in vivo mouse micronucleus assays.. Impairment of FertilityThe 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.

CLINICAL PHARMACOLOGY SECTION.

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 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, and alterations in body musculature and fat distribution.Male hypogonadism, clinical syndrome resulting from insufficient secretion of testosterone, has two main etiologies. Primary hypogonadism is caused by defects of the gonads, such as Klinefelters 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 Vogelxo.. 12.3 Pharmacokinetics. In single-dose, replicate crossover clinical study evaluating 58 hypogonadal males, the serum testosterone exposures (AUC0-24 and AUC0-t) and maximum testosterone concentration (Cmax) following topical administration of 100 mg testosterone administration as 2 5 Vogelxo tubes (applied to the shoulders/upper arms) were bioequivalent to those following topical administration of an approved testosterone gel product.. AbsorptionTestosterone gel delivers physiologic amounts of testosterone, producing circulating testosterone concentrations that approximate normal levels (e.g., 300 1000 ng/dL) seen in healthy men.The skin serves as 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 24-hour period.. Single DoseIn single dose, replicate crossover study, when Vogelxo 100 mg was applied, absorption of testosterone into the blood continued for the entire 24 hour dosing period. The average (+- SD) AUC0-24 and AUC0-t and Cmax were 6625 (+-3671) nghr/dL, 10425 (+-5521) nghr/dL, and 573 (+-284) ng/dL, respectively.. Multiple DoseWith single daily applications of testosterone gel 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 summarizes the 24-hour pharmacokinetic profile of testosterone for patients maintained on testosterone gel 50 mg or testosterone gel 100 mg for 30 days.Figure Mean Steady-State Serum Testosterone (+-SD) (ng/dL) Concentrations on Day 30 in Patients Applying Testosterone Once DailyThe average daily testosterone concentration produced by testosterone gel 100 mg at Day 30 was 612 (+- 286) ng/dL and by testosterone gel 50 mg at Day 30 was 365 (+- 187) ng/dL.. Figure 1. DistributionCirculating 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.. MetabolismTestosterone is metabolized to various 17-keto steroids through two different pathways. The major active metabolites of testosterone are estradiol and DHT. The average daily DHT concentration produced by testosterone gel 100 mg at Day 30 was 555 (+- 293) pg/mL and by testosterone gel 50 mg at Day 30 was 346 (+- 212) pg/mL.Figure summarizes the 24-hour pharmacokinetic profile of DHT for patients maintained on testosterone gel 50 mg or testosterone gel 100 mg for 30 days.Figure Mean Steady-State Serum Dihydrotestosterone (+-SD) (pg/mL) Concentrations on Day 30 in Patients Applying Testosterone Once Daily. Figure 2. ExcretionThere is considerable variation in the half-life of testosterone concentration as reported in the literature, ranging from 10 to 100 minutes. About 90% of 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 dose is excreted in the feces, mostly in the unconjugated form. Inactivation of testosterone occurs primarily in the liver.. Potential for Transfer from Male Patients to Female PartnersThe potential for dermal testosterone transfer following Vogelxo use was evaluated in clinical study between males dosed with Vogelxo and their untreated female partners. Two (2) hours after application of 50 mg of testosterone from g of Vogelxo to upper arm and shoulder of one side by the male subjects, the couples (N 48 couples) engaged in 15 minute session of skin-to-skin contact. Serum concentrations of testosterone were monitored in the female subjects for 24 hours after the transfer procedure. Under these study conditions, unprotected female partners had mean testosterone AUC0-24 and Cmax that were 2.8 and times greater than their mean baseline values, respectively. When shirt covered the application site or the application site was washed, study results showed less than 10% increase in testosterone AUC0-24 and Cmax, compared to baseline in these females.. Effect of Hand WashingIn clinical study conducted to evaluate the effect of hand washing on the residual amount of testosterone, 36 healthy male subjects received 50 mg of testosterone from g of Vogelxo on hand and applied testosterone gel to the upper arm and shoulder of one side. Subjects washed their hands with liquid soap and warm water immediately after drug application. Then the hand was allowed to air dry or patted dry with cloth towel. skin swab sample was collected and analyzed for testosterone content. mean (SD) of 0.16 (0.46) to 0.65(1.03) ug of residual testosterone (i.e., 99% reduction compared to when hands were not washed) was recovered after washing hands with liquid soap and warm water.. Effect of ShoweringThe effect of showering (with mild soap) at 1, and hours post application of testosterone gel 100 mg was evaluated in clinical trial in 12 men. The study demonstrated that the overall effect of washing was to decrease testosterone concentrations; however, when washing occurred two or more hours post drug application, serum testosterone concentrations remained within the normal range.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. 14.1 Clinical Study in Hypogonadal Males. Testosterone gel was evaluated in randomized multicenter, multi-dose, active and placebo controlled 90-day study in 406 adult males with morning testosterone levels <=300 ng/dL. The study was double-blind for the doses of testosterone gel and placebo, but open label for the non-scrotal testosterone transdermal system. During the first 60 days, patients were evenly randomized to testosterone gel 50 mg, testosterone gel 100 mg, placebo gel, or testosterone transdermal system. At Day 60, patients receiving testosterone gel were maintained at the same dose, or were titrated up or down within their treatment group, based on 24-hour averaged serum testosterone concentration levels obtained on Day 30.Of 192 hypogonadal men who were appropriately titrated with testosterone gel and who had sufficient data for analysis, 74% achieved an average serum testosterone level within the normal range (300 to 1,000 ng/dL) on treatment Day 90.Table summarizes the mean testosterone concentrations on Day 30 for patients receiving testosterone gel 50 mg or 100 mg.Table 4: Mean (+- SD) Steady-State Serum Testosterone Concentrations on Day 30Testosterone gel50 mgTestosterone gel100 mgPlacebo geln=94n=95n=93Cavg (ng/dL)365 +- 187612 +- 286216 +- 79Cmax (ng/dL)538 +- 371897 +- 565271 +- 110Cmin (ng/dL)223 +- 126394 +-189164 +- 64.

DRUG ABUSE AND DEPENDENCE SECTION.

9 DRUG ABUSE AND DEPENDENCE. 9.1 Controlled Substance. Vogelxo contains testosterone, Schedule III controlled substance in the Controlled Substances Act.. 9.2 Abuse. Drug abuse is intentional non-therapeutic use of 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 pharmacy, may be abused by athletes and bodybuilders. There have been reports of misuse by men taking higher doses of legally obtained testosterone than prescribed and continuing testosterone despite adverse events or against medical advice.. Abuse-Related Adverse ReactionsSerious 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 population of uncertain size and may include abuse of other agents, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.. 9.3 Dependence. Behaviors Associated with AddictionContinued abuse of testosterone and other anabolic steroids, leading to addiction is characterized by the following behaviors:Taking greater dosages than prescribedContinued drug use despite medical and social problems due to drug useSpending significant time to obtain the drug when supplies of the drug are interruptedGiving higher priority to drug use than other obligationsHaving difficulty in discontinuing the drug despite desires and attempts to do soExperiencing withdrawal symptoms upon abrupt discontinuation of usePhysical dependence is characterized by withdrawal symptoms after abrupt drug discontinuation or significant dose reduction of 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.. 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 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.

DRUG INTERACTIONS SECTION.

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 in patients taking warfarin. (7.2)Use of testosterone with corticosteroids may result in increased fluid retention. Use with caution, particularly in patients with cardiac, renal or hepatic disease. (7.3). 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 in patients taking warfarin. (7.2). Use of testosterone with 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 necessitate 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.

FEMALES & MALES OF REPRODUCTIVE POTENTIAL SECTION.

8.3 Females and Males of Reproductive Potential. InfertilityDuring treatment with large doses of exogenous androgens, including Vogelxo, spermatogenesis may be suppressed through feedback inhibition of the hypothalamic-pituitary-testicular axis [see Warnings and Precautions (5.8)]. 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.

GERIATRIC USE SECTION.

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)].

HEPATIC IMPAIRMENT SUBSECTION.

8.7 Hepatic Impairment. No studies were conducted in patients with hepatic impairment.

LACTATION SECTION.

8.2 Lactation. Risk SummaryVogelxo is not indicated for use in women.

MECHANISM OF ACTION SECTION.

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 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, and alterations in body musculature and fat distribution.Male hypogonadism, clinical syndrome resulting from insufficient secretion of testosterone, has two main etiologies. Primary hypogonadism is caused by defects of the gonads, such as Klinefelters syndrome or Leydig cell aplasia, whereas secondary hypogonadism is the failure of the hypothalamus (or pituitary) to produce sufficient gonadotropins (FSH, LH).

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. CarcinogenicityTestosterone 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.. MutagenesisTestosterone was negative in the in vitro Ames and in the in vivo mouse micronucleus assays.. Impairment of FertilityThe 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.

OVERDOSAGE SECTION.

10 OVERDOSAGE. There were no reports of overdose in the testosterone gel clinical trials. There is 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 cerebrovascular accident.Treatment of overdosage would consist of discontinuation of Vogelxo, washing the application site with soap and water, and appropriate symptomatic and supportive care.

8.4 Pediatric Use. The safety and efficacy of Vogelxo 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.

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics. No specific pharmacodynamic studies were conducted using Vogelxo.

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. In single-dose, replicate crossover clinical study evaluating 58 hypogonadal males, the serum testosterone exposures (AUC0-24 and AUC0-t) and maximum testosterone concentration (Cmax) following topical administration of 100 mg testosterone administration as 2 5 Vogelxo tubes (applied to the shoulders/upper arms) were bioequivalent to those following topical administration of an approved testosterone gel product.. AbsorptionTestosterone gel delivers physiologic amounts of testosterone, producing circulating testosterone concentrations that approximate normal levels (e.g., 300 1000 ng/dL) seen in healthy men.The skin serves as 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 24-hour period.. Single DoseIn single dose, replicate crossover study, when Vogelxo 100 mg was applied, absorption of testosterone into the blood continued for the entire 24 hour dosing period. The average (+- SD) AUC0-24 and AUC0-t and Cmax were 6625 (+-3671) nghr/dL, 10425 (+-5521) nghr/dL, and 573 (+-284) ng/dL, respectively.. Multiple DoseWith single daily applications of testosterone gel 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 summarizes the 24-hour pharmacokinetic profile of testosterone for patients maintained on testosterone gel 50 mg or testosterone gel 100 mg for 30 days.Figure Mean Steady-State Serum Testosterone (+-SD) (ng/dL) Concentrations on Day 30 in Patients Applying Testosterone Once DailyThe average daily testosterone concentration produced by testosterone gel 100 mg at Day 30 was 612 (+- 286) ng/dL and by testosterone gel 50 mg at Day 30 was 365 (+- 187) ng/dL.. Figure 1. DistributionCirculating 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.. MetabolismTestosterone is metabolized to various 17-keto steroids through two different pathways. The major active metabolites of testosterone are estradiol and DHT. The average daily DHT concentration produced by testosterone gel 100 mg at Day 30 was 555 (+- 293) pg/mL and by testosterone gel 50 mg at Day 30 was 346 (+- 212) pg/mL.Figure summarizes the 24-hour pharmacokinetic profile of DHT for patients maintained on testosterone gel 50 mg or testosterone gel 100 mg for 30 days.Figure Mean Steady-State Serum Dihydrotestosterone (+-SD) (pg/mL) Concentrations on Day 30 in Patients Applying Testosterone Once Daily. Figure 2. ExcretionThere is considerable variation in the half-life of testosterone concentration as reported in the literature, ranging from 10 to 100 minutes. About 90% of 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 dose is excreted in the feces, mostly in the unconjugated form. Inactivation of testosterone occurs primarily in the liver.. Potential for Transfer from Male Patients to Female PartnersThe potential for dermal testosterone transfer following Vogelxo use was evaluated in clinical study between males dosed with Vogelxo and their untreated female partners. Two (2) hours after application of 50 mg of testosterone from g of Vogelxo to upper arm and shoulder of one side by the male subjects, the couples (N 48 couples) engaged in 15 minute session of skin-to-skin contact. Serum concentrations of testosterone were monitored in the female subjects for 24 hours after the transfer procedure. Under these study conditions, unprotected female partners had mean testosterone AUC0-24 and Cmax that were 2.8 and times greater than their mean baseline values, respectively. When shirt covered the application site or the application site was washed, study results showed less than 10% increase in testosterone AUC0-24 and Cmax, compared to baseline in these females.. Effect of Hand WashingIn clinical study conducted to evaluate the effect of hand washing on the residual amount of testosterone, 36 healthy male subjects received 50 mg of testosterone from g of Vogelxo on hand and applied testosterone gel to the upper arm and shoulder of one side. Subjects washed their hands with liquid soap and warm water immediately after drug application. Then the hand was allowed to air dry or patted dry with cloth towel. skin swab sample was collected and analyzed for testosterone content. mean (SD) of 0.16 (0.46) to 0.65(1.03) ug of residual testosterone (i.e., 99% reduction compared to when hands were not washed) was recovered after washing hands with liquid soap and warm water.. Effect of ShoweringThe effect of showering (with mild soap) at 1, and hours post application of testosterone gel 100 mg was evaluated in clinical trial in 12 men. The study demonstrated that the overall effect of washing was to decrease testosterone concentrations; however, when washing occurred two or more hours post drug application, serum testosterone concentrations remained within the normal range.

PREGNANCY SECTION.

8.1 Pregnancy. Risk SummaryVogelxo is contraindicated in pregnant women. Testosterone is teratogenic and may cause fetal harm when administered to pregnant woman based on data from animal studies and its mechanism of action [see Contraindications (4) and Clinical Pharmacology (12.1)]. Exposure of 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 DataIn 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 ano-genital 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 or decreased 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.

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 SummaryVogelxo is not indicated for use in women.. 8.3 Females and Males of Reproductive Potential. InfertilityDuring treatment with large doses of exogenous androgens, including Vogelxo, spermatogenesis may be suppressed through feedback inhibition of the hypothalamic-pituitary-testicular axis [see Warnings and Precautions (5.8)]. 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 Vogelxo 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.

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Monitor patients with benign prostatic hyperplasia (BPH) for worsening of signs and symptoms of BPH. (5.1)Avoid unintentional exposure of women or children to Vogelxo. Secondary exposure to testosterone can produce signs of virilization. Vogelxo should be discontinued until the cause of virilization is identified. (5.2)Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), have been reported in patients using testosterone products. Evaluate patients with signs or symptoms consistent with DVT or PE. (5.4)Some postmarketing studies have shown an increased risk of myocardial infarction and stroke associated with use of testosterone replacement therapy. (5.5)Exogenous administration of androgens may lead to azoospermia. (5.8)Edema, with or without congestive heart failure, may be complication in patients with preexisting cardiac, renal, or hepatic disease. (5.10)Sleep apnea may occur in those with risk factors. (5.12)Monitor prostate specific antigen (PSA), hematocrit, and lipid concentrations periodically. (5.1, 5.3, 5.13)Vogelxo is flammable until dry. (5.16). Monitor patients with benign prostatic hyperplasia (BPH) for worsening of signs and symptoms of BPH. (5.1). Avoid unintentional exposure of women or children to Vogelxo. Secondary exposure to testosterone can produce signs of virilization. Vogelxo should be discontinued until the cause of virilization is identified. (5.2). Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), have been reported in patients using testosterone products. Evaluate patients with signs or symptoms consistent with DVT or PE. (5.4). Some postmarketing studies have shown an increased risk of myocardial infarction and stroke associated with use of testosterone replacement therapy. (5.5). Exogenous administration of androgens may lead to azoospermia. (5.8). Edema, with or without congestive heart failure, may be complication in patients with preexisting cardiac, renal, or hepatic disease. (5.10). Sleep apnea may occur in those with risk factors. (5.12). Monitor prostate specific antigen (PSA), hematocrit, and lipid concentrations periodically. (5.1, 5.3, 5.13). Vogelxo is flammable until dry. (5.16). 5.1 Worsening of Benign Prostatic Hyperplasia (BPH) and Potential Risk of Prostate Cancer. Men 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)]. Men 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 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 Vogelxo [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 physician and the possibility of secondary exposure to testosterone gel should also be brought to the attention of 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 to 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. 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 Vogelxo. Evaluate patients who report signs and 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 venous thromboembolic event is suspected, discontinue treatment with Vogelxo 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 Vogelxo. 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, Vogelxo 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 Vogelxo, 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 life-threatening or fatal complication. Long-term therapy with intramuscular testosterone enanthate, which elevate blood levels for prolonged periods, has produced multiple hepatic adenomas. Vogelxo is not known to produce 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 Vogelxo while the cause is evaluated.. 5.10 Edema. Androgens, including Vogelxo, may promote retention of sodium and water. Edema, with or without congestive heart failure, may be 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 any dose increases.. 5.14 Hypercalcemia. Androgens, including Vogelxo, 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 Vogelxo, 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 levels remain unchanged, however, and there is no clinical evidence of thyroid dysfunction.. 5.16 Flammability Alcohol-based products, including Vogelxo, are flammable; therefore, patients should be advised to avoid fire, flame or smoking until the Vogelxo has dried.
