2.1Administration and Use Instructions • Therapy with NORDITROPIN should be supervised by a physician who is experienced in the diagnosis and management of patients with the conditions for which NORDITROPIN is indicated [see Indications and Usage (1) ]. • Fundoscopic examination should be performed routinely before initiating treatment with NORDITROPIN to exclude preexisting papilledema, and periodically thereafter [see Warnings and Precautions (5.5) ]. • Administer NORDITROPIN by subcutaneous injection to the back of the upper arm, abdomen, buttocks, or thigh with regular rotation of injection sites to avoid lipoatrophy. • Inspect visually for particulate matter and discoloration.
NORDITROPIN should be clear and colorless. If the solution is cloudy or contains particulate matter do not use. • Instructions for delivering the dosage are provided in the PATIENT INFORMATION and INSTRUCTIONS FOR USE leaflets enclosed with the NORDITROPIN FlexPro prefilled pen.
2.2Pediatric Dosage • Individualize dosage for each patient based on the growth response. • Divide the calculated weekly NORDITROPIN 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: o Pediatric GH Deficiency: 0.17 mg/kg/week to 0.24 mg/kg/week (0.024 to 0.034 mg/kg/day) o Noonan Syndrome: Up to 0.46 mg/kg/week (up to 0.066 mg/kg/day) o Turner Syndrome: Up to 0.47 mg/kg/week (up to 0.067 mg/kg/day) o Small for Gestational Age (SGA): Up to 0.47 mg/kg/week (up to 0.067 mg/kg/day) • In very short pediatric patients, HSDS less than -3, and older pubertal pediatric patients consider initiating treatment with a larger dose of NORDITROPIN (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 HSDS values between -2 and -3, consider initiating treatment at 0.033 mg/kg/day and titrate the dose as needed. o Idiopathic Short Stature: Up to 0.47 mg/kg/week (up to 0.067 mg/kg/day) o Prader-Willi Syndrome: 0.24 mg/kg/week (0.034 mg/kg/day) • Assess compliance and evaluate other causes of poor growth such as hypothyroidism, under-nutrition, advanced bone age and antibodies to recombinant human growth hormone if patients experience failure to increase height velocity, particularly during the first year of treatment. • Discontinue NORDITROPIN for stimulation of linear growth once epiphyseal fusion has occurred [see Contraindications (4) ].
2.3Adult 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…

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS • Increased Risk of Neoplasms : Second neoplasms have occurred in childhood cancer survivors. Monitor patients with preexisting tumors for progression or recurrence. ( 5.3 ) • Glucose Intolerance and Diabetes Mellitus : NORDITROPIN may decrease insulin sensitivity, particularly at higher doses.
Monitor glucose levels periodically in all patients receiving NORDITROPIN, especially in patients with existing diabetes mellitus or at risk for development. ( 5.4 ) • Intracranial Hypertension (IH) : Has been reported usually within 8 weeks of initiation. Perform fundoscopic examinations prior to initiation and periodically thereafter.
If papilledema occurs, stop treatment. ( 5.5 ) • Severe Hypersensitivity : Serious hypersensitivity reactions may occur. In the event of an allergic reaction, seek prompt medical attention.
( 5.6 ) • Fluid Retention : May occur in adults and may be dose dependent. ( 5.7 ) • Hypoadrenalism : Monitor patients for reduced serum cortisol levels and/or need for glucocorticoid dose increases in those with known hypoadrenalism. ( 5.8 ) • Hypothyroidism : Monitor thyroid function periodically as hypothyroidism may occur or worsen after initiation of somatropin.
( 5.9 ) • Slipped Capital Femoral Epiphysis in Pediatric Patients : May occur; evaluate patients with onset of a limp or hip/knee pain. ( 5.10 ) • Progression of Preexisting Scoliosis in Pediatric Patients : Monitor patients with scoliosis for progression. ( 5.11 ) • Pancreatitis : Has been reported; consider pancreatitis in patients with abdominal pain, especially pediatric patients.
( 5.12 )
5.1Increased Mortality in Patients with Acute Critical Illness Increased mortality in patients with acute critical illness due to complications following open heart surgery, abdominal surgery or multiple accidental trauma, or those with acute respiratory failure has been reported after treatment with pharmacologic amounts of somatropin [see Contraindications (4) ]. Two placebo-controlled clinical trials in non-growth hormone deficient adult patients (n=522) with these conditions in intensive care units revealed a significant increase in mortality (42% vs.
19%) among somatropin-treated patients (doses 5.3-8 mg/day) compared to those receiving placebo. The safety of continuing NORDITROPIN treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. NORDITROPIN is not indicated for the treatment of non-GH deficient adults.
5.2Sudden Death in Pediatric Patients with Prader-Willi Syndrome There have been reports of sudden death after initiating therapy with somatropin in pediatric patients with Prader-Willi syndrome who had one or more of the following risk factors: severe obesity, history of upper airway obstruction or sleep apnea, or unidentified respiratory infection. Male patients with one or more of these factors may be at greater risk than females. Patients with Prader-Willi syndrome should be evaluated for signs of upper airway obstruction and sleep apnea before initiation of treatment with somatropin.
If, during treatment with NORDITROPIN, patients show signs of upper airway obstruction (including onset of or increased snoring) and/or new onset sleep apnea, treatment should be interrupted. All patients with Prader-Willi syndrome treated with NORDITROPIN should also have effective weight control and be monitored for signs of respiratory infection, which should be diagnosed as early as possible and treated aggressively [see Contraindications (4) ] .
5.3Increased Risk of Neoplasms Active Malignancy There is an increased risk of malignancy progression with somatropin treatment in patients with active malignancy [See Contraindications (4) ]. Any preexisting malignancy should be inactive and its treatment complete prior to instituting therapy with NORDITROPIN. Discontinue NORDITROPIN if there is evidence of recurrent activity. Risk of Second Neoplasm in Pediat…

6.1Clinical Trials Experience Because clinical trials are conducted under varying conditions, adverse reaction rates observed during the clinical trials performed with one somatropin product cannot always be directly compared to the rates observed during the clinical trials performed with another somatropin product, and may not reflect the adverse reaction rates observed in practice. Pediatric Patients Growth Failure due to Inadequate Secretion of Endogenous Growth Hormone In one randomized, open label, clinical study the most frequent adverse reactions were headache, pharyngitis, otitis media and fever.
There were no clinically significant differences between the three doses assessed in the study (0.025, 0.05 and 0.1 mg/kg/day). Short Stature Associated with Noonan Syndrome NORDITROPIN was studied in 21 pediatric patients, 3 years to 14 years of age at doses of 0.033 mg/kg/day and 0.066 mg/kg/day. After the two-year study, patients continued NORDITROPIN treatment until final height was achieved; randomized dose groups were not maintained.
Adverse reactions were later collected retrospectively from 18 pediatric patients; total follow-up was 11 years. An additional 6 pediatric patients were not randomized, but followed the protocol and are included in this assessment of adverse reactions. The most frequent adverse reactions were upper respiratory infection, gastroenteritis, ear infection, and influenza.
Cardiac disorders was the system organ class with the second most adverse reactions reported. Scoliosis was reported in 1 and 4 pediatric patients receiving doses of 0.033 mg/kg/day and 0.066 mg/kg/day respectively. The following additional adverse reactions also occurred once: insulin resistance and panic reaction for the 0.033 mg/kg/day dose group; injection site pruritus, bone development abnormal, depression, and self-injurious ideation in the 0.066 mg/kg/day dose group.
Headache occurred in 2 cases in the 0.066 mg/kg/day dose group. Short Stature Associated with Turner Syndrome In two clinical studies in pediatric patients that were treated until final height with various doses of NORDITROPIN, the most frequently reported adverse reactions were influenza-like illness, otitis media, upper respiratory tract infection, otitis externa, gastroenteritis, eczema and, impaired fasting glucose. Adverse reactions in study 1 were most frequent in the highest dose groups.
Three patients in study 1 had excessive growth of hands and/or feet in the high dose groups. Two patients in study 1 had a serious adverse reaction of exacerbation of…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Table 2 includes a list of drugs with clinically important drug interactions when administered concomitantly with NORDITROPIN and instructions for preventing or managing them. Table 2: Clinically Important Drug Interactions with NORDITROPIN Glucocorticoids 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. NORDITROPIN inhibits 11βHSD-1.
Consequently, individuals with untreated GH deficiency have relative increases in 11βHSD-1 and serum cortisol. Initiation of NORDITROPIN 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 NORDITROPIN [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. Pharmacologic Glucocorticoid Therapy and Supraphysiologic Glucocorticoid Treatment Clinical Impact: Pharmacologic glucocorticoid therapy and supraphysiologic glucocorticoid treatment may attenuate the growth promoting effects of NORDITROPIN in pediatric patients. Intervention: Carefully adjust glucocorticoid replacement 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. NORDITROPIN may alter the clearance of compounds known to be metabolized by CP450 liver enzymes. Intervention: Careful monitoring is advisable when NORDITROPIN 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 NORDITROPIN. Intervention: Patients receiving oral estrogen replacement may require greater NORDITROPIN dosages [see Dosage and Administration (2.3) ] . Insulin and/or Other Hypoglycemic Agents Clinical Impact: Treatment with NORDITROPIN 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) ]. • Glucocorticoids : Patients treated with glucocorticoid for hypoadrenalism may require an increase in their maintenance or stress doses following initiation of NORDITROPIN ( 7 ) • Pharmacologic Glucocorticoid Therapy and Supraphysiologic Glucocorticoid Treatment : Adjust glucocorticoid replacement dosing in pediatric patients receiving glucocorticoid treatment to avoid both hypoadrenalism and an inhibitory effect on growth.
( 7 ) • Cytochrome P450-Metabolized Drugs : NORDITROPIN may alter the clearance. Monitor carefully if used with NORDITROPIN ( 7 ) • Oral Estrogen : Larger doses of NORDITROPIN may be required ( 7 ) • Insulin and/or Other Hypoglycemic Agents : Dose adjustment of insulin or hypoglycemic agent may be required ( 5.4 , 7 )
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Limited available data with somatropin use in pregnant women are insufficient to determine a drug-associated risk of adverse developmental outcomes. In animal reproduction studies, there was no evidence of fetal or neonatal harm when pregnant rats were administered subcutaneous NORDITROPIN during organogenesis or during lactation at doses approximately 10-times higher than the maximal clinical dose of 0.016 mg/kg, based on body surface area (see Data). The estimated background risk of 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. Data Animal Data In an embryo-fetal development study, NORDITROPIN was administered via subcutaneous injection to pregnant rats from gestation Day 6 to 17, corresponding with the period of organogenesis. NORDITROPIN did not adversely affect fetal viability or developmental outcomes at maternal doses that were approximately 10-times the clinical dose of 0.016 mg/kg, based on body surface area.
In a pre- and post-natal development study in pregnant rats, NORDITROPIN was administered from gestation Day 17 through lactation Day 21 (weaning). No adverse developmental effects were observed in the offspring at doses up to 1.1 mg/kg (approximately 10 times the clinical dose of 0.016 mg/kg, based on body surface area).
8.2Lactation 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 on the breastfed infant have been reported with somatropin.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for NORDITROPIN and any potential adverse effects on the breastfed infant from NORDITROPIN or from the underlying maternal condition.
8.4Pediatric Use Safety and effectiveness of NORDITROPIN in pediatric patients have been established in growth failure due to inadequate secretion of endogenous growth hormone, short stature associated with Noonan syndrome, short stature associated with Turner syndrome, short stature in children born small for gestational age (SGA) with no catch-up growth by age 2 years to 4 years of age, idiopathic short stature (ISS), and growth failure due to Prader-Willi syndrome (PWS). Growth Failure due to Inadequate Secretion of Endogenous Growth Hormone Safety and effectiveness of NORDITROPIN have been established in pediatric patients with growth failure due to growth hormone deficiency in a multi-center, prospective, randomized, open-label, dose-response study in 111 pediatric patients conducted for a two-year period [see Clinical Studies (14.1) ].
Short Stature Associated with Noonan Syndrome Safety and effectiveness of NORDITROPIN have been established in pediatric patients with Noonan syndrome in a prospective, open-label, randomized, parallel group study in 21 pediatric patients conducted for 2 years [see Clinical Studies (14.2) ].

Short Stature in Pediatric Patients Born Small for Gestational Age (SGA) with No Catch-up Growth by Age 2 Years to 4 Years of Age Safety and effectiveness of NORDITROPIN have been established in pediatric patients with short stature born SGA with no catch-up growth in a multi-center, randomized, double-blind, two-arm study to final height in 53 pediatric patients and in a randomized study of 84 prepubertal, non-GHD, Japanese pediatric patients [see Clinical Studies (14.4) ]. Idiopathic Short Stature (ISS) Safety and effectiveness of NORDITROPIN have been established in pediatric patients with ISS based on data from a randomized, open-label clinical study with another somatropin product in 105 pediatric patients [see Clinical Studies (14.5) ].
Growth Failure Due to Prader-Willi Syndrome (PWS) Safety and effectiveness of NORDITROPIN have been established in pediatric patients with growth failure due to Prader-Willi Syndrome based on data from two randomized, open label, controlled clinical trials with another somatropin product in pediatric patients. There have been reports of sudden death after initiating therapy with somatropin in pediatric patients with Prader-Willi syndrome who had one or more of the following risk factors: severe obesity, history of upper airway obstruction or sleep apnea, or unidentified respiratory infection.
Male patients with one or more of these factors may be at greater risk than females. Patients with Prader-Willi syndrome should be evaluated for signs of upper airway obstruction and sleep apnea before initiation of treatment with somatropin. [see Contraindications (4) , Warnings and Precautions (5.2) , Clinical Studies (14.6) ].
🧓 Geriatric Use ▾
8.5Geriatric Use The safety and effectiveness of NORDITROPIN in patients aged 65 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 develop adverse reactions. A lower starting dose and smaller dose increments should be considered for older patients [see Dosage and Administration (2.3) ].
🆘 Overdosage ▾
10 OVERDOSAGE Short-term 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 growth hormone .
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism 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 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.
12.2Pharmacodynamics Subcutaneous administration of a single dose of 4 mg NORDITROPIN in healthy subjects (n=26) with suppressed endogenous growth hormone results in an increased mean (SD) IGF-1 level from 190 (46) ng/mL predose to maximal level of 276 (49) ng/mL after approx. 24 hours. After 96 hours, the subjects displayed a mean (SD) IGF-1 concentration of 196 (41) ng/mL, comparable to the predose value.
12.3Pharmacokinetics Absorption - Somatropin has been studied following subcutaneous and intravenous administration in adult healthy subjects and GHD patients. A single dose administration of 4 mg NORDITROPIN in healthy subjects (n=26) with suppressed endogenous growth hormone resulted in a mean (SD) C max of 34.9 (10.4) ng/mL after approximately 3.0 hours. After a 180-min IV infusion of NORDITROPIN (33 ng/kg/min) administered to GHD patients (n=9), a mean (SD) hGH steady state serum level of approximately 23.1 (15.0) ng/mL was reached at 150 min.
After a SC dose of 0.024 mg/kg or 3 IU/m 2 given in the thigh to adult GHD patients (n=18), mean (SD) C max values of 13.8 (5.8) and 17.1 (10.0) ng/mL were observed for the 4 and 8 mg NORDITROPIN vials, respectively, at approximately 4 to 5 hr. post dose. The absolute bioavailability for NORDITROPIN after the SC route of administration is currently not known. Distribution — The mean (SD) apparent volume of distribution of somatropin after single dose subcutaneous administration of 4 mg NORDITROPIN in healthy subjects is 43.9 (14.9) L.
Elimination Metabolism — Extensive metabolism studies have not been conducted. The metabolic fate of somatropin involves classical protein catabolism in both the liver and kidneys. Excretion – The mean apparent terminal T 1/2 values in healthy adult subjects (n=26) was 2.0 (0.5) hours.
In GHD patients receiving 180-min IV infusion of NORDITROPIN (33 ng/kg/min), a mean clearance rate of approximately 2.3 (1.8) mL/min/kg or 139 (105) mL/min for hGH was observed. Following infusion, serum hGH levels had a biexponential decay with a terminal elimination half-life (T 1/2 ) of approximately 21.1 (5.1) min. The mean apparent terminal T 1/2 values in GHD patients receiving a SC dose of 0.024 mg/kg or 3 IU/m 2 was estimated to be approximately 7 to 10 hr.
The longer half-life observed after subcutaneous administration is due to slow absorption from the injection site. Urinary excretion of intact somatropin has not been measured. Geriatric patients — The pharmacokinetics of somatropin have not been studied in patients greater than 65 years of age.
Pediatric patients — The pharmacokinetics of somatropin in pediatric patients are similar to those of adults. Male and Female Patients — No gender-specific pharmacokinetic studies have been performed with somatropin. The available literature indicates that the pharmacokinetics of somatropin are similar in men and women.
Patients with Renal or Hepatic Impairment — No studies have been performed with somatropin.
