1 INDICATIONS AND USAGE HUMATROPE is a recombinant human growth hormone indicated for: Pediatric Patients: growth failure due to inadequate secretion of endogenous growth hormone (GH); short stature associated with Turner syndrome; Idiopathic Short Stature (ISS), height standard deviation score (SDS) <-2.25, and associated with growth rates unlikely to permit attainment of adult height in the normal range; short stature or growth failure in short stature homeobox-containing gene (SHOX) deficiency; short stature born small for gestational age (SGA) with no catch-up growth by 2 years to 4 years of age. ( 1.1 ) Adult Patients: replacement of endogenous GH in adults with GH deficiency. ( 1.2 ) 1.1 Pediatric Patients HUMATROPE is indicated for the treatment of pediatric patients with: growth failure due to inadequate secretion of endogenous growth hormone (GH), short stature associated with Turner syndrome, Idiopathic Short Stature (ISS), height standard deviation score (SDS) <-2.25, and associated with growth rates unlikely to permit attainment of adult height in the normal range, short stature or growth failure in short stature homeobox-containing gene (SHOX) deficiency, short stature born small for gestational age (SGA) with no catch-up growth by 2 years to 4 years of age. 1.2 Adult Patients HUMATROPE is indicated for the replacement of endogenous GH in adults with GH deficiency.

2 DOSAGE AND ADMINISTRATION Administer by subcutaneous injection to the back of upper arm, abdomen, buttock, or thigh with regular rotation of injection sites. ( 2.1 ) Pediatric Dosage - divide the calculated weekly dosage into equal doses given either 6, or 7 days per week. GHD: 0.18 mg/kg/week to 0.3 mg/kg/week. ( 2.2 ) Turner Syndrome: Up to 0.375 mg/kg/week. ( 2.2 ) ISS: Up to 0.37 mg/kg/week. ( 2.2 ) SHOX Deficiency: 0.35 mg/kg/week. ( 2.2 ) SGA: Up to 0.47 mg/kg/week. ( 2.2 ) Adult Dosage - Either of the following two dosing regimens may be used: Non-weight based dosing: Initiate with a dose of approximately 0.2 mg/day (range: 0.15 mg/day-0.3 mg/day) and increase the dose every 1-2 months by increments of approximately 0.1 mg/day-0.2 mg/day, according to individual patient requirements ( 2.3 ) Weight-based dosing (Not recommended for obese patients): Initiate at 0.006 mg/kg daily and increase the dose according to individual patient requirements to a maximum of 0.0125 mg/kg daily ( 2.3 ) See Full Prescribing Information for reconstitution instructions. ( 2.4 ) 2.1 Administration and Use Instructions Therapy with HUMATROPE should be supervised by a physician who is experienced in the diagnosis and management of patients with the conditions for which HUMATROPE is indicated [see Indications and Usage ( 1 )] . Fundoscopic examination should be performed routinely before initiating treatment with HUMATROPE to exclude preexisting papilledema, and periodically thereafter [see Warnings and Precautions ( 5.5 )] . Leave HUMATROPE at room temperature for 10 minutes prior to administration. Administer HUMATROPE by subcutaneous injection to the back of the upper arm, abdomen, buttock, or thigh with regular rotation of injection sites to avoid lipoatrophy. 2.2 Pediatric Dosage Individualize dosage for each patient based on the growth response. Divide the calculated weekly HUMATROPE dosage into equal doses given either 6 or 7 days per week. The recommended weekly dose in milligrams (mg) per kilogram (kg) of body weight for pediatric patients is: Pediatric GH Deficiency: 0.18 mg/kg/week to 0.3 mg/kg/week (0.026 to 0.043 mg/kg/day) Turner Syndrome: Up to 0.375 mg/kg/week (up to.054 mg/kg/day) Idiopathic Short Stature: Up to 0.37 mg/kg/week (up to 0.053 mg/kg/day) SHOX Deficiency: 0.35 mg/kg/week (0.05 mg/kg/day) Small for Gestational Age (SGA): Up to 0.47 mg/kg/week (up to 0.067 mg/kg/day) In very short pediatric patients, height SDS less than -3, and older pubertal pediatric patients consider initiating treatment with a larger dose of HUMATROPE (up to 0.067 mg/kg/day). Consider a gradual reduction in dosage if substantial catch-up growth is observed during the first few years of therapy. In pediatric patients less than 4 years of age with less severe short stature, baseline height SDS values between -2 and -3, consider initiating treatment at 0.033 mg/kg/day and titrate the dose as needed. Assess compliance and evaluate other causes of poor growth such as hypothyroidism, under-nutrition, advanced bone age and antibodies to recombinant human GH if patients experience failure to increase height velocity, particularly during the first year of treatment. Discontinue HUMATROPE for stimulation of linear growth once epiphyseal fusion has occurred [see Contraindications ( 4 )] . 2.3 Adult Dosage Patients who were treated with somatropin for GH deficiency in childhood and whose epiphyses are closed should be reevaluated before continuation of somatropin for GH deficient adults. Consider using a lower starting dose and smaller dose increment increases for geriatric patients as they may be at increased risk for adverse reactions with HUMATROPE than younger individuals [see Use in Specific Populations ( 8.5 )] . Women may require higher doses and patients receiving oral estrogen may require higher doses [see Drug Interactions ( 7 )] . Administer the prescribed dose daily. Either of two HUMATROPE dosing regimens may be used: Non-weight based: Initia …

Pediatric Patients Growth Failure Due to Inadequate Secretion of Endogenous Growth Hormone In an uncontrolled open-label study, 314 treatment-naive children aged >2 years who had GH deficiency were treated with HUMATROPE (0.06 mg/kg 3 times per week) for up to 8 years. Adverse reactions of special interest are reported in Table 2 . Table 2: Adverse Reactions of Special Interest Occurring in Humatrope-Treated Patients with Growth Failure Due to Inadequate Secretion of Endogenous Growth Hormone in an Open-label Study for Up to 8 Years a Dose=0.06 mg/kg 3 times per week for up to 8 years. b n=1 Adverse Reaction HUMATROPE a (n=314) Hypothyroidism 25% Allergic reaction 11% Arthralgia 6% Bone disorder 4% Edema 4% Injection site pain/reaction 4% Neoplasm/tumor 2% Cardiovascular disorders 1% Thyroid disorders 1% Intracranial hypertension 0% b Short Stature Associated with Turner Syndrome In a randomized, concurrent-controlled (untreated), open-label study until attainment of adult height, the adverse reactions of special interest occurring in 74 patients treated with Humatrope at dose 0.3 mg/kg/week (mean duration 4.1 years) and in 62 untreated patients (mean duration 3.7 years) are reported in Table 3 . A similar increase in otitis media was observed in an 18-month placebo-controlled study.

7 DRUG INTERACTIONS Table 8 includes a list of drugs with clinically important drug interactions when administered concomitantly with HUMATROPE and instructions for preventing or managing them. Table 8: Clinically Important Drug Interactions with HUMATROPE Replacement Glucocorticoid Treatment Clinical Impact: Microsomal enzyme 11β-hydroxysteroid dehydrogenase type 1 (11βHSD-1) is required for conversion of cortisone to its active metabolite, cortisol, in hepatic and adipose tissue. HUMATROPE inhibits 11βHSD-1. Consequently, individuals with untreated GH deficiency have relative increases in 11βHSD-1 and serum cortisol. Initiation of HUMATROPE may result in inhibition of 11βHSD-1 and reduced serum cortisol concentrations. Intervention: Patients treated with glucocorticoid replacement for hypoadrenalism may require an increase in their maintenance or stress doses following initiation of HUMATROPE [see Warnings and Precautions ( 5.8 )]. Examples: Cortisone acetate and prednisone may be effected more than others since conversion of these drugs to their biologically active metabolites is dependent on the activity of 11βHSD-1. Non-Replacement Glucocorticoid Treatment in Pediatric Patients Clinical Impact: Non-replacement glucocorticoid treatment, including supraphysiologic glucocorticoid treatment, may attenuate the growth promoting effects of HUMATROPE in pediatric patients. Intervention: Carefully adjust glucocorticoid dosing in pediatric patients receiving glucocorticoid treatments to avoid both hypoadrenalism and an inhibitory effect on growth. Cytochrome P450-Metabolized Drugs Clinical Impact: Limited published data indicate that somatropin treatment increases cytochrome P450 (CP450)-mediated antipyrine clearance. HUMATROPE may alter the clearance of compounds known to be metabolized by CP450 liver enzymes. Intervention: Careful monitoring is advisable when HUMATROPE is administered in combination with drugs metabolized by CP450 liver enzymes. Oral Estrogen Clinical Impact: Oral estrogens may reduce the serum IGF-1 response to HUMATROPE. Intervention: Patients receiving oral estrogen may require greater HUMATROPE dosages [see Dosage and Administration ( 2.3 )] . Insulin and/or Other Hypoglycemic Agents Clinical Impact: Treatment with HUMATROPE may decrease insulin sensitivity, particularly at higher doses. Intervention: Patients with diabetes mellitus may require adjustment of their doses of insulin and/or other hypoglycemic agents [see Warnings and Precautions ( 5.4 )]. Replacement Glucocorticoid Treatment: Patients treated with glucocorticoids for hypoadrenalism may require an increase in their maintenance or stress doses following initiation of HUMATROPE. ( 7 ) Non-Replacement Glucocorticoid Treatment in Pediatric Patients: Adjust glucocorticoid dosing in pediatric patients receiving glucocorticoid treatment to avoid both hypoadrenalism and an inhibitory effect on growth. ( 7 ) Cytochrome P450-Metabolized Drugs: HUMATROPE may alter the clearance. Monitor carefully if used with HUMATROPE. ( 7 ) Oral Estrogen: Patients may require larger doses of HUMATROPE. ( 7 ) Insulin and/or Other Hypoglycemic Agents: Dose adjustment of insulin or hypoglycemic agent may be required. ( 5.4 , 7 )

8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary Limited available data with somatropin use in pregnant women are insufficient to determine a drug-associated risk of adverse developmental outcomes. Animal reproduction studies have not been conducted with HUMATROPE. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. 8.2 Lactation Risk Summary There is no information regarding the presence of somatropin in human milk. Limited published data indicate that exogenous somatropin does not increase normal breastmilk concentrations of growth hormone. No adverse effects related to somatropin in the breastfed infant have been reported. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for HUMATROPE and any potential adverse effects on the breastfed infant from HUMATROPE or from the underlying maternal condition. 8.4 Pediatric Use Safety and effectiveness of HUMATROPE in pediatric patients have been established in growth failure due to inadequate secretion of endogenous growth hormone, short stature associated with Turner syndrome, idiopathic short stature (ISS), short stature or growth failure in SHOX deficiency, and short stature in children born small for gestational age (SGA) with no catch-up growth by 2 years to 4 years of age. Growth Failure due to Inadequate Secretion of Endogenous Growth Hormone Safety and effectiveness of HUMATROPE have been established in pediatric patients with growth failure due to growth hormone deficiency based on data from an open-label, uncontrolled, multicenter study with HUMATROPE in 314 pediatric patients conducted for up to 8 years [see Clinical Studies ( 14.1 )] . Short Stature Associated with Turner Syndrome Safety and effectiveness of HUMATROPE have been established in pediatric patients with short stature associated with Turner syndrome based on data from one long-term, randomized, open-label, multicenter, concurrently controlled study; two long-term, open-label multicenter, historically controlled US studies; and one long-term, randomized, US dose-response study with HUMATROPE in 181 pediatric patients [see Clinical Studies ( 14.2 )] . Idiopathic Short Stature (ISS) Safety and effectiveness of HUMATROPE have been established in pediatric patients with ISS based on data from two randomized, multicenter studies, one placebo-controlled study and one dose-response study with HUMATROPE in 310 pediatric patients [see Clinical Studies ( 14.3 )] . Short Stature or Growth Failure in SHOX Deficiency Safety and effectiveness of HUMATROPE have been established in pediatric patients with short stature or growth failure in SHOX deficiency based on data from a randomized, controlled, two-year, three-arm, open-label study with HUMATROPE in 52 pediatric patients [see Clinical Studies ( 14.4 )] . Short Stature in Children Born Small for Gestational Age (SGA) with No Catch-up Growth by 2 Years to 4 Years of Age Safety and effectiveness of HUMATROPE have been established in pediatric patients with short stature born SGA with no catch-up growth based on data from two clinical studies with HUMATROPE in 214 pediatric patients [see Clinical Studies ( 14.5 )] . 8.5 Geriatric Use The safety and effectiveness of HUMATROPE in patients aged 65 years and over has not been evaluated in clinical studies. Elderly patients may be more sensitive to the action of somatropin, and therefore may be more prone to development of adverse reactions. A lower starting dose and smaller dose increments should be considered for older patients [see Dosage and Administration ( 2.3 )] .

12.1 Mechanism of Action Somatropin binds to dimeric GH receptors located within the cell membranes of target tissue cells. This interaction results in intracellular signal transduction and subsequent induction of transcription and translation of GH-dependent proteins including IGF-1, IGF BP-3 and acid-labile subunit. Somatropin has direct tissue and metabolic effects or mediated indirectly by IGF-1, including stimulation of chondrocyte differentiation, and proliferation, stimulation of hepatic glucose output, protein synthesis and lipolysis. Somatropin stimulates skeletal growth in pediatric patients with GHD as a result of effects on the growth plates (epiphyses) of long bones. The stimulation of skeletal growth increases linear growth rate (height velocity) in most somatropin-treated pediatric patients. Linear growth is facilitated in part by increased cellular protein synthesis.

11 DESCRIPTION Somatropin is a human growth hormone (GH) produced by recombinant DNA technology using Escherichia coli. The protein is comprised of 191 amino acid residues and has a molecular weight of about 22,125 daltons. The amino acid sequence is identical to that of human GH of pituitary origin. HUMATROPE (somatropin) for injection is a sterile, white, lyophilized powder intended for subcutaneous injection after reconstitution supplied in a cartridge. Phosphoric acid and/or sodium hydroxide may have been added to adjust the pH. Reconstituted solutions have a pH of approximately 7.5. This product is oxygen sensitive. Cartridge — Each single-patient-use cartridge of HUMATROPE contains either 6 mg (18 IU), 12 mg (36 IU), or 24 mg (72 IU) of somatropin. Each HUMATROPE cartridge contains the following components (see Table 9 ): Table 9: Contents of HUMATROPE Component Cartridge 6 mg (gold) 12 mg (teal) 24 mg (purple) Somatropin 6 mg 12 mg 24 mg Dibasic sodium phosphate 1.36 mg 2.72 mg 5.43 mg Glycine 6 mg 12 mg 24 mg Mannitol 18 mg 36 mg 72 mg Each cartridge is co-packaged with an accompanying syringe containing approximately 3 mL of diluent containing Water for Injection with 0.3% metacresol as a preservative and 1.7%, 0.29%, and 0.29% glycerin in the 6, 12, and 24 mg cartridges, respectively.

10 OVERDOSAGE Acute overdosage could lead initially to hypoglycemia and subsequently to hyperglycemia. Overdose with somatropin is likely to cause fluid retention. Long-term overdosage could result in signs and symptoms of gigantism and/or acromegaly consistent with the known effects of excess endogenous growth hormone.
