Drug Description

NORDITROPIN®
(somatropin) injection for subcutaneous use

DESCRIPTION

NORDITROPIN(somatropin) for injection is a recombinant human growth hormone. It is a polypeptide of recombinant DNA origin and is synthesized by a special strain of E. coli bacteria that has been modified by the addition of a plasmid which carries the gene for human growth hormone.

NORDITROPINcontains the identical sequence of 191 amino acids constituting the naturally occurring pituitary human growth hormone with a molecular weight of about 22,000 Daltons.

NORDITROPINis supplied as a sterile solution for subcutaneous use in ready-to-administer prefilled pens with a volume of 1.5 mL or 3 mL.

Each NORDITROPINcontains the following (see Table 3):

Indications & Dosage

INDICATIONS

Pediatric Patients

NORDITROPIN is indicated for the treatment of pediatric patients with:

  • growth failure due to inadequate secretion of endogenous growth hormone (GH),
  • short stature associated with Noonan syndrome,
  • short stature associated with Turner syndrome,
  • short stature born small for gestational age (SGA) with no catch-up growth by age 2 years to 4 years of age,
  • 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,
  • growth failure due to Prader-Willi syndrome (PWS).

Adult Patients

NORDITROPINis indicated for the replacement of endogenous GH in adults with growth hormone deficiency (GHD)

DOSAGE AND ADMINISTRATION

Administration 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].
  • Fundoscopic examination should be performed routinely before initiating treatment with NORDITROPIN to exclude preexisting papilledema, and periodically thereafter [see WARNINGS AND PRECAUTIONS].
  • 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.

Pediatric 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:
    • Pediatric GH Deficiency: 0.17 mg/kg/week to 0.24 mg/kg/week (0.024 to 0.034 mg/kg/day)
    • Noonan Syndrome: Up to 0.46 mg/kg/week (up to 0.066 mg/kg/day)
    • Turner Syndrome: Up to 0.47 mg/kg/week (up to 0.067 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, 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.
    • Idiopathic Short Stature: Up to 0.47 mg/kg/week (up to 0.067 mg/kg/day)
    • 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, undernutrition, 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].

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 NORDITROPIN than younger individuals [see Use In Specific Populations].
  • Estrogen-replete women and patients receiving oral estrogen may require higher doses [see DRUG INTERACTIONS].
  • Administer the prescribed dose daily.
  • Either of two NORDITROPIN dosing regimens may be used:
    • Non-weight based
      • Initiate NORDITROPIN with a dose of approximately 0.2 mg/day (range, 0.15 mg/day to 0.3 mg/day) and increase the dose every 1-2 months by increments of approximately 0.1 mg/day to 0.2 mg/day, according to individual patient requirements based on the clinical response and serum insulin-like growth factor 1 (IGF-1) concentrations.
      • Decrease the dose as necessary on the basis of adverse reactions and/or serum IGF-1 concentrations above the age- and gender-specific normal range.
      • Maintenance dosages will vary considerably from person to person, and between male and female patients.
    • Weight-based
      • Initiate NORDITROPIN at 0.004 mg/kg daily and increase the dose according to individual patient requirements to a maximum of 0.016 mg/kg daily.
      • Use the patient’s clinical response, adverse reactions, and determination of age- and gender-adjusted serum IGF-1 concentrations as guidance in dose titration.
      • Not recommended for obese patients as they are more likely to experience adverse reactions with this regimen

Side Effects

SIDE EFFECTS

The following important adverse reactions are also described elsewhere in the labeling:

Clinical 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

NORDITROPINwas 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 NORDITROPINtreatment 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 preexisting scoliosis in the 0.045 mg/kg/day group.

Small for Gestational Age (SGA) with No Catch-up Growth by Age 2-4 Years

In a study, 53 pediatric patients were treated with 2 doses of NORDITROPIN(0.033 or 0.067 mg/kg/day) to final height for up to 13 years (mean duration of treatment 7.9 and 9.5 years for girls and boys, respectively). The most frequently reported adverse reactions were influenza-like illness, upper respiratory tract infection, bronchitis, gastroenteritis, abdominal pain, otitis media, pharyngitis, arthralgia, headache, gynecomastia, and increased sweating. One pediatric patient treated with 0.067 mg/kg/day for 4 years was reported with disproportionate growth of the lower jaw, and another patient treated with 0.067 mg/kg/day developed a melanocytic nevus. 4 pediatric patients treated with 0.067 mg/kg/day and 2 pediatric patients treated with 0.033 mg/kg/day of NORDITROPIN had increased fasting blood glucose levels after 1 year of treatment. In addition, small increases in mean fasting blood glucose and insulin levels after 1 and 2 years of NORDITROPIN treatment appeared to be dosedependent.

In a second study, 98 Japanese pediatric patients were treated with 2 doses of NORDITROPIN(0.033 or 0.067 mg/kg/day) for 2 years or were untreated for 1 year. Adverse reactions were otitis media, arthralgia and impaired glucose tolerance. Arthralgia and transiently impaired glucose tolerance were reported in the 0.067 mg/kg/day treatment group.

Idiopathic Short Stature

In two open-label clinical studies with another somatropin product in pediatric patients, the most common adverse reactions were upper respiratory tract infections, influenza, tonsillitis, nasopharyngitis, gastroenteritis, headaches, increased appetite, pyrexia, fracture, altered mood, and arthralgia.

Growth Failure Due to Prader-Willi Syndrome

In two clinical studies in pediatric patients with PWS carried out with another somatropin product, the following adverse reactions were reported: edema, aggressiveness, arthralgia, benign intracranial hypertension, hair loss, headache, and myalgia.

Immunogenicity

As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to NORDITROPINwith the incidence of antibodies to other products may be misleading. In the case of growth hormone, antibodies with binding capacities lower than 2 mg/mL have not been associated with growth attenuation. In a very small number of patients treated with somatropin, when binding capacity was greater than 2 mg/mL, interference with the growth response was observed.

In clinical trials, GH deficient pediatric patients receiving NORDITROPINfor up to 12 months were tested for induction of antibodies, and 0/358 patients developed antibodies with binding capacities above 2 mg/L. Amongst these patients, 165 had previously been treated with other somatropin formulations, and 193 were previously untreated naive patients. Eighteen of 76 children (˜24%) treated with NORDITROPINfor short stature born SGA developed anti-rhGH antibodies.

Post-Marketing Experience

Because these adverse 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.

Immune system disorders - Serious systemic hypersensitivity reactions including anaphylactic reactions and angioedema

Skin - Increase in size or number of cutaneous nevi

Endocrine disorders - Hypothyroidism

Metabolism and nutrition disorders - Hyperglycemia

Musculoskeletal and connective tissue disorders -Slipped capital femoral epiphysis- Legg-Calvé- Perthes disease

Investigations - Increase in blood alkaline phosphatase level - Decrease in serum thyroxin (T4) levels

Gastrointestinal - Pancreatitis.

Neoplasm - Leukemia has been reported in a small number of GH deficient children treated with somatropin, somatrem (methionylated rhGH) and GH of pituitary origin

Drug Interactions

DRUG INTERACTIONS

Table 2 includes a list of drugs with clinically important drug interactions when administered concomitantly with NORDITROPINand 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. NORDITROPINinhibits 11βHSD-1. Consequently, individuals with untreated GH deficiency have relative increases in 11βHSD-1 and serum cortisol. Initiation of NORDITROPINmay 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].
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 NORDITROPINin 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 NORDITROPINis 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 NORDITROPINdosages [see DOSAGE AND ADMINISTRATION].
Insulin and/or Other Hypoglycemic Agents
Clinical Impact: Treatment with NORDITROPINmay 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].

Warnings & Precautions

WARNINGS

Included as part of the "PRECAUTIONS" Section

PRECAUTIONS

Increased 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]. 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 NORDITROPINtreatment 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.

Sudden 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 reactions with this regimen effective weight control and be monitored for signs of respiratory infection, which should be diagnosed as early as possible and treated aggressively [see CONTRAINDICATIONS].

Increased Risk Of Neoplasms

Active Malignancy

There is an increased risk of malignancy progression with somatropin treatment in patients with active malignancy [See CONTRAINDICATIONS]. 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 Pediatric Patients

There is an increased risk of a second neoplasm in pediatric cancer survivors who were treated with radiation to the brain/head and who developed subsequent GH deficiency and were treated with somatropin. Intracranial tumors, in particular meningiomas, were the most common of these second neoplasms. In adults, it is unknown whether there is any relationship between somatropin replacement therapy and CNS tumor recurrence. Monitor all patients receiving NORDITROPIN who have a history of GH deficiency secondary to an intracranial neoplasm for progression or recurrence of the tumor.

New Malignancy During Treatment

Because pediatric patients with certain rare genetic causes of short stature have an increased risk of developing malignancies, thoroughly consider the risks and benefits of starting NORDITROPIN in these patients. If NORDITROPIN is initiated, carefully monitor patients for development of neoplasms.

Monitor all patients receiving NORDITROPIN carefully for increased growth, or potential malignant changes, of preexisting nevi. Advise patients/caregivers to report marked changes in behavior, onset of headaches, vision disturbances and/or changes in skin pigmentation or changes in the appearance of preexisting nevi.

Glucose Intolerance And Diabetes Mellitus

Treatment with somatropin may decrease insulin sensitivity, particularly at higher doses. New onset type 2 diabetes mellitus has been reported in patients taking somatropin. Previously undiagnosed impaired glucose tolerance and overt diabetes mellitus may be unmasked. Monitor glucose levels periodically in all patients receiving NORDITROPIN, especially in those with risk factors for diabetes mellitus, such as obesity, Turner syndrome, or a family history of diabetes mellitus. Patients with preexisting type 1 or type 2 diabetes mellitus or impaired glucose tolerance should be monitored closely. The doses of antidiabetic agents may require adjustment when NORDITROPIN is initiated.

Intracranial Hypertension

Intracranial hypertension (IH) with papilledema, visual changes, headache, nausea, and/or vomiting has been reported in a small number of patients treated with somatropin products. Symptoms usually occurred within the first eight (8) weeks after the initiation of somatropin therapy. In all reported cases, IH-associated signs and symptoms rapidly resolved after cessation of therapy or a reduction of the somatropin dose. Funduscopic examination should be performed routinely before initiating treatment with NORDITROPIN to exclude preexisting papilledema, and periodically thereafter. If papilledema is observed by funduscopy during somatropin treatment, treatment should be stopped. If somatropininduced IH is diagnosed, treatment with NORDITROPINcan be restarted at a lower dose after IHassociated signs and symptoms have resolved. Patients with Turner syndrome may be at increased risk for the development of IH.

Severe Hypersensitivity

Serious systemic hypersensitivity reactions including anaphylactic reactions and angioedema have been reported with postmarketing use of somatropin products. Patients and caregivers should be informed that such reactions are possible and that prompt medical attention should be sought if an allergic reaction occurs [see CONTRAINDICATIONS].

Fluid Retention

Fluid retention during somatropin replacement therapy in adults may frequently occur. Clinical manifestations of fluid retention (e.g. edema, arthralgia, myalgia, nerve compression syndromes including carpal tunnel syndrome/paraesthesias) are usually transient and dose dependent.

Hypoadrenalism

Patients receiving somatropin therapy who have or are at risk for pituitary hormone deficiency(s) may be at risk for reduced serum cortisol levels and/or unmasking of central (secondary) hypoadrenalism. In addition, patients treated with glucocorticoid replacement for previously diagnosed hypoadrenalism may require an increase in their maintenance or stress doses following initiation of NORDITROPINtreatment. Monitor patients for reduced serum cortisol levels and/or need for glucocorticoid dose increases in those with known hypoadrenalism [see DRUG INTERACTIONS].

Hypothyroidism

Undiagnosed/untreated hypothyroidism may prevent an optimal response to NORDITROPIN, in particular, the growth response in pediatric patients. Patients with Turner syndrome have an inherently increased risk of developing autoimmune thyroid disease and primary hypothyroidism. In patients with GH deficiency, central (secondary) hypothyroidism may first become evident or worsen during somatropin treatment. Therefore, patients should have periodic thyroid function tests and thyroid hormone replacement therapy should be initiated or appropriately adjusted when indicated.

Slipped Capital Femoral Epiphysis In Pediatric Patients

Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders (including GH deficiency and Turner syndrome) or in patients undergoing rapid growth. Evaluate pediatric patients with the onset of a limp or complaints of hip or knee pain.

Progression Of Preexisting Scoliosis In Pediatric Patients

Somatropin increases the growth rate, and progression of existing scoliosis can occur in patients who experience rapid growth. Somatropin has not been shown to increase the occurrence of scoliosis. Monitor patients with a history of scoliosis for progression of scoliosis.

Pancreatitis

Cases of pancreatitis have been reported in pediatric patients and adults receiving somatropin products. There may be a greater risk in pediatric patients compared with adults. Published literature indicates that females who have Turner syndrome may be at greater risk than other pediatric patients receiving somatropin products. Pancreatitis should be considered in patients who develop persistent severe abdominal pain.

Lipoatrophy

When somatropin products are administered subcutaneously at the same site over a long period of time, tissue atrophy may result. Rotate injection sites when administering NORDITROPIN to reduce this risk [see Administration And Use Instructions.]

Laboratory Tests

Serum levels of inorganic phosphorus, alkaline phosphatase, parathyroid hormone (PTH) and IGF-I may increase after NORDITROPIN treatment.

Patient Counseling Information

See FDA-approved PATIENT INFORMATION.

Advise the patient to read the FDA-approved patient labeling ( PATIENT INFORMATION and Instructions for Use).

  • Neoplasms – Advise childhood cancer survivors/caregivers that individuals treated with brain/head radiation are at increased risk of secondary neoplasms and as a precaution need to be monitored for recurrence. Advise patients/caregivers to report marked changes in behavior, onset of headaches, vision disturbances and/or changes in skin pigmentation or changes in the appearance of pre-existing nevi.
  • Fluid Retention - Advise patients that fluid retention during NORDITROPINreplacement therapy in adults may frequently occur. Inform patients of the clinical manifestations of fluid retention (e.g. edema, arthralgia, myalgia, nerve compression syndromes including carpal tunnel syndrome/paraesthesias) and to report to their healthcare provider any of these signs or symptoms occur during treatment with NORDITROPIN.
  • Pancreatitis - Advise patients/caregivers that pancreatitis may develop and to report to their healthcare provider any new onset abdominal pain.
  • Hypoadrenalism - Advise patients/caregivers who have or who are at risk for pituitary hormone deficiency(s) that hypoadrenalism may develop and to report to their healthcare provider if they experience hyperpigmentation, extreme fatigue, dizziness, weakness, or weight loss.
  • Hypothyroidism - Advise patients/caregivers that undiagnosed/untreated hypothyroidism may prevent an optimal response to NORDITROPIN. Advise patients/caregivers they may require periodic thyroid function tests.
  • Intracranial Hypertension - Advise patients/caregivers to report to their healthcare provider any visual changes, headache, and nausea and/or vomiting.
  • Hypersensitivity Reactions – Advise patients/caregivers that serious systemic hypersensitivity reactions (anaphylaxis and angioedema) are possible and that prompt medical attention should be sought if an allergic reaction occurs.
  • Glucose Intolerance/ Diabetes Mellitus – Advise patients/caregivers that new onset impaired glucose intolerance/diabetes mellitus or exacerbation of preexisting diabetes mellitus can occur and monitoring of blood glucose during treatment with NORDITROPINmay be needed.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Carcinogenicity and mutagenicity studies have not been conducted with NORDITROPIN.

Impairment Of Fertility

In a rat study evaluating female fertility, animals were administered once daily subcutaneous doses of 0.1, 0.3, and 1.1 mg/kg NORDITROPINbeginning two weeks prior to mating, throughout mating and during the first 7 days of pregnancy. Delays in the time to mating were observed at doses greater than or equal to 0.3 mg/kg (approximately 3 times the maximum adult clinical dose of 0.016 mg/kg, based on body surface area), but these doses were also associated with increases in the number of corpora lutea and implantations. A decrease in the pregnancy rate was observed at the dose of 1.1 mg/kg (approximately 10 times the clinical dose of 0.016 mg/kg, based on body surface area). Male fertility parameters have not been evaluated with administration of NORDITROPIN.

Use In Specific Populations

Pregnancy

Risk Summary

Limited available data with somatropin use in pregnant women are insufficient to determine a drugassociated risk of adverse developmental outcomes. In animal reproduction studies, there was no evidence of fetal or neonatal harm when pregnant rats were administered subcutaneous NORDITROPINduring 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, NORDITROPINwas administered via subcutaneous injection to pregnant rats from gestation Day 6 to 17, corresponding with the period of organogenesis. NORDITROPINdid 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, NORDITROPINwas 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).

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 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 NORDITROPINand any potential adverse effects on the breastfed infant from NORDITROPINor from the underlying maternal condition.

Pediatric 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, doseresponse study in 111 pediatric patients conducted for a two-year period [see Clinical Studies].

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].

Short Stature Associated With Turner Syndrome

Safety and effectiveness of NORDITROPIN have been established in pediatric patients with short stature associated with Turner syndrome in two randomized, parallel group, open-label, multicenter studies in 87 pediatric patients [see Clinical Studies].

Short Stature In Children 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].

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].

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, WARNINGS AND PRECAUTIONS, Clinical Studies].

Geriatric Use

The safety and effectiveness of NORDITROPINin 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].

Overdosage & Contraindications

OVERDOSE

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.

CONTRAINDICATIONS

NORDITROPIN is contraindicated in patients with:

  • Acute critical illness after open heart surgery, abdominal surgery or multiple accidental trauma, or those with acute respiratory failure due to the risk of increased mortality with use of pharmacologic doses of somatropin [see WARNINGS AND PRECAUTIONS].
  • Pediatric patients with Prader-Willi syndrome who are severely obese, have a history of upper airway obstruction or sleep apnea, or have severe respiratory impairment due to the risk of sudden death [see WARNINGS AND PRECAUTIONS].
  • Active Malignancy [see WARNINGS AND PRECAUTIONS].
  • Hypersensitivity to NORDITROPIN or any of its excipients. Systemic hypersensitivity reactions have been reported with postmarketing use of somatropin products [see WARNINGS AND PRECAUTIONS].
  • Active proliferative or severe non-proliferative diabetic retinopathy.
  • Pediatric patients with closed epiphyses.
Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism Of Action

Somatropin (as well as endogenous GH) binds to a dimeric GH receptor in the cell membrane of target cells resulting in intracellular signal transduction and a host of pharmacodynamic effects. Some of these pharmacodynamic effects are primarily mediated by IGF-I produced in the liver and also locally (e.g., skeletal growth, protein synthesis), while others are primarily a consequence of the direct effects of somatropin (e.g., lipolysis) [see Pharmacodynamics].

Pharmacodynamics

Tissue Growth

The primary and most intensively studied action of somatropin is the stimulation of linear growth. This effect is demonstrated in children with GHD.

Skeletal Growth

The measurable increase in bone length after administration of somatropin results from its effect on the cartilaginous growth areas of long bones. Studies in vitro have shown that the incorporation of sulfate into proteoglycans is not due to a direct effect of somatropin, but rather is mediated by the somatomedins or insulin-like growth factors (IGFs). The somatomedins, among them IGF-I, are polypeptide hormones which are synthesized in the liver, kidney, and various other tissues. IGF-I levels are low in the serum of hypopituitary dwarfs and hypophysectomized humans or animals, and increase after treatment with somatropin.

Cell Growth

It has been shown that the total number of skeletal muscle cells is markedly decreased in children with short stature lacking endogenous GH compared with normal children, and that treatment with somatropin results in an increase in both the number and size of muscle cells.

Organ Growth

Somatropin influences the size of internal organs, and it also increases red cell mass.

Protein Metabolism

Linear growth is facilitated in part by increased cellular protein synthesis. This synthesis and growth are reflected by nitrogen retention which can be quantitated by observing the decline in urinary nitrogen excretion and blood urea nitrogen following the initiation of somatropin therapy.

Carbohydrate Metabolism

Hypopituitary children sometimes experience fasting hypoglycemia that may be improved by treatment with somatropin. In healthy subjects, large doses of somatropin may impair glucose tolerance. Although the precise mechanism of the diabetogenic effect of somatropin is not known, it is attributed to blocking the action of insulin rather than blocking insulin secretion. Insulin levels in serum actually increase as somatropin levels increase. Administration of human growth hormone to normal adults and patients with growth hormone deficiency results in increases in mean serum fasting and postprandial insulin levels, although mean values remain in the normal range. In addition, mean fasting and postprandial glucose and hemoglobin A1c levels remain in the normal range.

Lipid Metabolism

Somatropin stimulates intracellular lipolysis, and administration of somatropin leads to an increase in plasma free fatty acids and triglycerides. Untreated GHD is associated with increased body fat stores, including increased abdominal visceral and subcutaneous adipose tissue. Treatment of growth hormone deficient patients with somatropin results in a general reduction of fat stores, and decreased serum levels of low density lipoprotein (LDL) cholesterol.

Mineral Metabolism

Administration of somatropin results in an increase in total body potassium and phosphorus and to a lesser extent sodium. This retention is thought to be the result of cell growth. Serum levels of phosphate increase in children with GHD after somatropin therapy due to metabolic activity associated with bone growth. Serum calcium levels are not altered. Although calcium excretion in the urine is increased, there is a simultaneous increase in calcium absorption from the intestine. Negative calcium balance, however, may occasionally occur during somatropin treatment.

Connective Tissue Metabolism

Somatropin stimulates the synthesis of chondroitin sulfate and collagen, and increases the urinary excretion of hydroxyproline.

Pharmacokinetics

A 180-min IV infusion of Norditropin (33 ng/kg/min) was administered to 9 GHD patients. A mean (±SD) hGH steady state serum level of approximately 23.1 (±15.0) ng/mL was reached at 150 min and 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 (T1/2) of approximately 21.1 (±5.1) min.

In a study conducted in 18 GHD adult patients, where a SC dose of 0.024 mg/kg or 3 IU/m2 was given in the thigh, mean (±SD) Cmax 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 mean apparent terminal T1/2 values were estimated to be approximately 7 to 10 hr. However, the absolute bioavailability for Norditropin after the SC route of administration is currently not known.

Clinical Studies

Short Stature In Children With Noonan Syndrome

A prospective, open label, randomized, parallel group trial with 21 children was conducted for 2 years to evaluate the efficacy and safety of Norditropin treatment for short stature in children with Noonan syndrome. An additional 6 children were not randomized, but did follow the protocol. After the initial two-year trial, children continued on Norditropin until final height. Retrospective final height and adverse event data were collected from 18 of the 21 subjects who were originally enrolled in the trial and the 6 who had followed the protocol without randomization. Historical reference materials of height velocity and adult height analyses of Noonan patients served as the controls.

The twenty-four (24) (12 female, 12 male) children 3 - 14 years of age received either 0.033 mg/kg/day or 0.066 mg/kg/day of Norditropin subcutaneously which, after the first 2 years, was adjusted based on growth response.

In addition to a diagnosis of Noonan syndrome, key inclusion criteria included bone age determination showing no significant acceleration, prepubertal status, height SDS <-2, and HV SDS <1 during the 12 months pre-treatment. Exclusion criteria were previous or ongoing treatment with growth hormone, anabolic steroids or corticosteroids, congenital heart disease or other serious disease perceived to possibly have major impact on growth, FPG >6.7 mmol/L (>120 mg/dL), or growth hormone deficiency (peak GH levels <10 ng/mL).

Patients obtained a final height (FH) gain from baseline of 1.5 and 1.6 SDS estimated according to the national and the Noonan reference, respectively. A height gain of 1.5 SDS (national) corresponds to a mean height gain of 9.9 cm in boys and 9.1 cm in girls at 18 years of age, while a height gain of 1.6 SDS (Noonan) corresponds to a mean height gain of 11.5 cm in boys and 11.0 cm in girls at 18 years of age.

A comparison of HV between the two treatment groups during the first two years of treatment for the randomized subjects was 10.1 and 7.6 cm/year with 0.066 mg/kg/day versus 8.55 and 6.7 cm/year with 0.033 mg/kg/day, for Year 1 and Year 2, respectively.

Age at start of treatment was a factor for change in height SDS (national reference). The younger the age at start of treatment, the larger the change in height SDS.

Examination of gender subgroups did not identify differences in response to Norditropin.

Not all patients with Noonan syndrome have short stature; some will achieve a normal adult height without treatment. Therefore, prior to initiating Norditropin for a patient with Noonan syndrome, establish that the patient does have short stature.

Short Stature In Children With Turner Syndrome

Two randomized, parallel group, open label, multicenter studies were conducted in the Netherlands to evaluate the efficacy and safety of Norditropin for the treatment of children with short stature associated with Turner syndrome. Patients were treated to final height in both studies [height velocity (HV) < 2 cm/year]. Changes in height were expressed as standard deviation scores (SDS) utilizing reference data for untreated Turner syndrome patients as well as the national Dutch population.

In Study 1 (the primary study), 68 euthyroid Caucasian patients stratified based on age and baseline height SDS were randomized in a 1:1:1 ratio to three different Norditropin treatment regimens: 0.045 mg/kg/day (Dose A) for the entire study; 0.045 mg/kg/day for the first year and 0.067 mg/kg/day thereafter (Dose B); or 0.045 mg/kg/day for the first year, 0.067 for the second year, and 0.089 mg/kg/day thereafter (Dose C). Overall, at baseline, mean age was 6.5 years, mean height SDS (National standard) was -2.7, and mean HV during the previous year was 6.5 cm/year. Patients also received estrogen therapy after age 12 and following four years of Norditropin treatment if they did not have spontaneous puberty.

Patients were treated for a mean of 8.4 years. As seen in Table 3, overall mean final height was 161 cm in the 46 children who attained final height. Seventy percent of these children reached a final height within the normal range (height SDS > -2 using the National standard). A greater percentage of children in the two escalated dose groups reached normal final height. The mean changes from baseline to final height in height SDS after treatment with Dose B and Dose C were significantly greater than the mean changes observed after treatment with Dose A (utilizing both the National and Turner standards). The mean changes from baseline to final height in height SDS (Turner standard) in Table 3 correspond to mean height gains of 9.4, 14.1 and 14.4 cm after treatment with Doses A, B and C, respectively. The mean changes from baseline to final height in height SDS (National standard) in Table 3 correspond to mean height gains of 4.5, 9.1 and 9.4 cm after treatment with Doses A, B and C, respectively. In each treatment group, peak HV was observed during treatment Year 1, and then gradually decreased each year; during Year 4, HV was less than the pre-treatment HV. However, between Year 2 and Year 6, a greater HV was observed in the two dose escalation groups compared to the 0.045 mg/kg/day group.

In Study 2 (a supportive study), 19 euthyroid Caucasian patients (with bone age ≤13.9 years) were randomized to treatment with 0.067 mg/kg/day of Norditropin as a single subcutaneous dose in the evening, or divided into two doses (1/3 morning and 2/3 evening). All subjects were treated with concomitant ethinyl estradiol. Overall, at baseline, mean age was 13.6 years, mean height SDS (National standard) was -3.5 and mean HV during the previous year was 4.3 cm/year. Patients were treated for a mean of 3.6 years. In that there were no significant differences between the two treatment groups for any linear growth variables, the data from all patients were pooled. Overall mean final height was 155 cm in the 17 children who attained final height. Height SDS changed significantly from -3.5 at baseline to -2.4 at final height (National standard), and from 0.7 to 1.3 at final height (Turner standard).

Short Stature In Children Born Small For Gestational Age (SGA) With No Catch-Up Growth By Age 2-4 Years

A multi-center, randomized, double-blind, two-arm study to final height (Study 1) and a 2-year, multi-center, randomized, double-blind, parallel-group study (Study 2) were conducted to assess the efficacy and safety of Norditropin in children with short stature born SGA with no catch-up growth. Changes in height and height velocity were compared to a national reference population in both studies.

Study 1

The pivotal study included 53 (38 male, 15 female) non-GHD, Dutch children 3-11 years of age with short stature born SGA with no catch-up growth. Catch-up growth was defined as obtaining a height of ≥ 3rd percentile within the first 2 years of life or at a later stage. These prepubertal children needed to meet the following additional inclusion criteria: birth length < 3rd percentile for gestational age, and height velocity (cm/year) for chronological age < 50th percentile. Exclusion criteria included chromosomal abnormalities, signs of a syndrome (except for Silver-Russell syndrome), serious/chronic co-morbid disease, malignancy, and previous rhGH therapy. Norditropin was administered subcutaneously daily at bedtime at a dose of approximately 0.033 (Dose A) or 0.067 mg/kg/day (Dose B) for the entire treatment period. Final height was defined as a height velocity below 2 cm/year. Treatment with Norditropin was continued to final height for up to 13 years. Mean duration of treatment was 9.5 years (boys) and 7.9 years (girls).

38 out of 53 children (72%) reached final height. Sixty-three percent (24 out of 38) of the children who reached final height were within the normal range of their healthy peers (Dutch national reference). For both doses combined, actual mean final height was 171 (SD 6.1) cm in boys and 159 (SD 4.3) cm in girls.

As seen in Table 4, for boys and girls combined, both mean final height SDS (Dose A, -1.8 vs. Dose B, -1.3), and increase in height SDS from baseline to final height (Dose A, 1.4 vs. Dose B, 1.8), were significantly greater after treatment with Dose B (0.067 mg/kg/day). A similar dose response was observed for the increase in height SDS from baseline to Year 2 (Table 4).

Overall mean height velocity at baseline was 5.4 cm/y (SD 1.2; n=29). Height velocity was greatest during the first year of Norditropin treatment and was significantly greater after treatment with Dose B (mean 11.1 cm/y [SD 1.9; n=19]) compared with Dose A (mean 9.7 cm/y [SD 1.3; n=10]).

Study 2

In this study, 84 randomized, prepubertal, non-GHD, Japanese children (age 3-8) with short stature born SGA with no catch-up growth were treated for 2 years with 0.033 or 0.067 mg/kg/day of Norditropin subcutaneously daily at bedtime or received no treatment for 1 year. Additional inclusion criteria included birth length or weight SDS ≤ -2 or < 10th percentile for gestational age, height SDS for chronological age ≤ -2, and height velocity SDS for chronological age < 0 within one year prior to Visit 1. Exclusion criteria included diabetes mellitus, history or presence of active malignancy, and serious co-morbid conditions.

As seen in Table 5, for boys and girls combined, there was a dose-dependent increase in height SDS at Year 1 and Year 2. The increase in height SDS from baseline to Year 2 (0.033 mg/kg/day, 0.8 vs. 0.067 mg/kg/day, 1.4) was significantly greater after treatment with 0.067 mg/kg/day. In addition, the increase in height SDS at Year 1 was significantly greater in both active treatment groups compared to the untreated control group.

Adult Growth Hormone Deficiency (GHD)

A total of six randomized, double-blind, placebo-controlled studies were performed. Two representative studies, one in adult onset (AO) GHD patients and a second in childhood onset (CO) GHD patients, are described below.

Study 1

A single center, randomized, double-blind, placebo-controlled, parallel-group, six month clinical trial was conducted in 31 adults with AO GHD comparing the effects of Norditropin (somatropin) for injection and placebo on body composition. Patients in the active treatment arm were treated with Norditropin 0.017 mg/kg/day (not to exceed 1.33 mg/day). The changes from baseline in lean body mass (LBM) and percent total body fat (TBF) were measured by total body potassium (TBP) after 6 months.

Treatment with Norditropin produced a significant (p=0.0028) increase from baseline in LBM compared to placebo (Table 6).

Fifteen (48.4%) of the 31 randomized patients were male. The adjusted mean treatment differences on the increase in LBM and decrease in percent TBF from baseline were larger in males compared to females.

Norditropin also significantly increased serum osteocalcin (a marker of osteoblastic activity).

Study 2

A single center, randomized, double-blind, placebo-controlled, parallel-group, dose-finding, six month clinical trial was conducted in 49 men with CO GHD comparing the effects of Norditropin and placebo on body composition. Patients were randomized to placebo or one of three active treatment groups (0.008, 0.016, and 0.024 mg/kg/day). Thirty three percent of the total dose to which each patient was randomized was administered during weeks 1-4, 67% during weeks 5-8, and 100% for the remainder of the study. The changes from baseline in LBM and percent TBF were measured by TBP after 6 months.

Treatment with Norditropin produced a significant (p=0.0079) increase from baseline in LBM compared to placebo (pooled data) (Table 8).

Norditropin also significantly reduced intraabdominal, extraperitoneal and total abdominal fat volume, waist/hip ratio and LDL cholesterol, and significantly increased serum osteocalcin.

Forty four men were enrolled in an open label follow up study and treated with Norditropin for as long as 30 additional months. During this period, the reduction in waist/hip ratio achieved during the initial six months of treatment was maintained.

What are the possible side effects of NORDITROPIN?

NORDITROPIN may cause serious side effects, including:

  • high risk of death in people who have critical illnesses because of heart or stomach surgery, trauma or serious breathing (respiratory) problems.
  • high risk of sudden death in children with Prader-Willi syndrome who are severely obese or have breathing problems, including sleep apnea.
  • increased risk of growth of cancer or a tumor that is already present and increased risk of the return of cancer or a tumor in people who were treated with radiation to the brain or head as children and who developed low growth hormone problems. Your or your child’s healthcare provider will need to monitor you or your child for a return of cancer or a tumor. Contact the healthcare provider if you or your child starts to have headaches, or have changes in behavior, changes in vision, or changes in moles, birthmarks, or the color of your skin.
  • new or worsening high blood sugar (hyperglycemia) or diabetes. Your or your child’s blood sugar may need to be monitored during treatment with NORDITROPIN.
  • increase in pressure in the skull (intracranial hypertension). If you or your child has headaches, eye problems, nausea or vomiting, contact the healthcare provider.
  • serious allergic reactions. Get medical help right away if you or your child has the following symptoms:
    • swelling of your face, lips, mouth, or tongue
    • trouble breathing
    • wheezing
    • severe itching
    • skin rashes, redness, or swelling
    • dizziness or fainting
    • fast heartbeat or pounding in your chest
    • sweating
  • your body holding too much fluid (fluid retention) such as swelling in the hands and feet, pain in your joints or muscles or nerve problems that cause pain, burning or tingling in the hands, arms, legs and feet. Fluid retention can happen in adults during treatment with NORDITROPIN. Tell your healthcare provider if you have any of these signs or symptoms of fluid retention.
  • decrease in a hormone called cortisol. The healthcare provider will do blood tests to check your or your child’s cortisol levels. Tell your or your child’s healthcare provider if you or your child has darkening of the skin, severe fatigue, dizziness, weakness, or weight loss.
  • decrease in thyroid hormone levels. Decreased thyroid hormone levels may affect how well NORDITROPIN works. The healthcare provider will do blood tests to check your or your child’s thyroid hormone levels.
  • hip and knee pain or a limp in children (slipped capital femoral epiphysis)
  • worsening of curvature of the spine (scoliosis)
  • severe and constant abdominal pain. This could be a sign of pancreatitis. Tell your or your child’s healthcare provider if you or your child has any new abdominal pain.
  • loss of fat and tissue weakness in the area of skin you inject. Talk to your healthcare provider about rotating the areas where you inject NORDITROPIN.
  • increase in phosphorus, alkaline phosphatase and parathyroid hormone levels in your blood. Your or your child’s healthcare provider will do blood tests to check this.

Step 3. Priming a new Pen.

  • Checking the growth hormone flow in the pen (priming) is not needed for a Pen you have used before. If the Pen has already been primed, go to Step 4.
  • Before you use a new Pen you must first prepare it for use. Hold the Pen with one hand and turn the dose selector clockwise to select 0.025 mg. You will hear a faint click when you turn the dose selector. This is the smallest amount of medicine for a dose. See Figure I.
  • This is the smallest amount of medicine for a dose - Illustration

    Figure I

  • Hold the Pen with the needle pointing up. Tap the top of the Pen gently a few times to let any air bubbles rise to the top. See Figure J.
  • Tap the top of the Pen - Illustration

    Figure J

  • Press the dose button until the “0” in the display window lines up with the pointer and a drop of liquid appears at the needle tip. See Figure K.
  • Press the dose button until the “0” in the display window lines up with the pointer and a drop of liquid appears at the needle tip - Illustration

    Figure K

  • If no drop appears, repeat Step 3 again up to 6 times.
  • If you still do not see a drop of liquid, change the needle and repeat Step 3 again.
  • If a drop of liquid still does not appear after repeating Step 3 and changing the needle, call Novo Nordisk at 1-888-668-6444 for help.

Step 4. Selecting the correct dose of Norditropin.

  • Use the dose selector on your Norditropin FlexPro Pen to make sure you have the exact dose selected. You can select up to 2 mg per dose.
  • To start, check that the pointer on the Pen is set at “0”. See Figure L.
  • To start, check that the pointer on the Pen is set at “0” - Illustration

    Figure L

  • Select the dose you need by turning the dose selector clockwise. If you go beyond your dose, turn the dose selector counterclockwise until the right number of mg lines up with the pointer.
  • To guide you, the dose selector click sound is different when turned clockwise (softer click) or counterclockwise (louder click). You will hear a click for every single unit dialed.
  • When dialing counterclockwise, be careful not to press the dose button as liquid will come out.
  • You can use the growth hormone scale on the side of the Pen to see approximately how much growth hormone is left in the Pen. You can also use the dose selector to see exactly how much growth hormone is left in the Pen.
  • If the Pen contains less than 2 mg, turn the dose selector until it stops. The number that lines up with the pointer shows how many mg is left in the Pen.
  • You cannot set a dose higher than the number of mg left in the Pen.
  • If there is not enough Norditropin left in the Pen to deliver your full dose, use a new Norditropin FlexPro Pen to inject the remaining amount of your dose or contact your healthcare provider.
  • Remember to subtract the dose already received. For example, if the dose is 0.7 mg and you can only set the dose selector to 0.35 mg, you should inject another 0.35 mg with a new Norditropin FlexPro Pen. See Figure L.

Important:

  • Never use the Pen clicks to count the number of mg you select. Only the display window and pointer will show the exact number.
  • Never use the growth hormone scale to measure how much liquid to inject. Only the display window and pointer will show the exact number.

Step 5. Selecting the injection site and injecting the dose of Norditropin.

  • Change the injection site every day.
  • Select the injection site and wipe the skin with an alcohol swab as your healthcare provider showed you.
  • Insert the needle under the skin as your healthcare provider showed you. See Figure M.
  • Insert the needle under the skin as your healthcare provider showed you - Illustration

    Figure M

  • After inserting the needle into the skin, push and hold the dose button in as far as it will go to give the dose. Inject until the “0” in the display window lines up with the pointer. As you do this, you may hear or feel a firm click. See Figure M.
  • If you remove your finger from the dose button before the “0” is in the display window the full dose has not been received. Leave the needle in the skin and press and hold the dose button again until the “0” lines up with the pointer.

If the injection button cannot be pushed in completely or “0” does not appear in the display window, you did not receive the full dose. Call Novo Nordisk at 1-888-668-6444 for assistance. You may need a new Pen.

  • After the “0” in the display window lines up with the pointer, leave the needle under the skin for at least 6 seconds to make sure that you get your full dose. Let go of the dose button while you wait.

Important:

  • Always press the dose button to inject the dose. Turning the dose selector will not inject the dose.
  • Never touch the display window when you inject, as this can block the injection.
  • Carefully lift the pen to remove the needle from the skin. After that, you may see a drop of liquid at the needle tip. This is normal and does not affect the dose you received. See Figure N.
  • Carefully lift the pen to remove the needle from the skin - Illustration

    Figure N

Step 6. What to do after the injection is completed.

  • Do not recap the needle. Recapping a needle can lead to a needle stick injury. Remove the needle from the Pen after each injection.
  • Carefully remove the needle from the Pen by turning the needle in a counterclockwise direction. See Figure O.
  • Carefully remove the needle from the Pen by turning the needle in a counterclockwise direction - Illustration

    Figure O

  • Put the Pen cap back on.
  • If there is medicine left in the Pen, store the Pen as directed in the Patient Information that comes with this Pen.
  • If the Pen is empty, throw the Pen away as directed below. Put your used needles and Pen in a FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles and Pens in your household trash.
  • If you do not have a FDA-cleared sharps disposal container, you may use a household container that is:
    • made of a heavy-duty plastic,
    • can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out,
    • upright and stable during use,
    • leak-resistant, and
    • properly labeled to warn of hazardous waste inside the container.
  • When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used needles and Pens. For more information about safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA’s website at: http://www.fda.gov/safesharpsdisposal.
  • Do not dispose of your used sharps disposal container in your household trash unless your community guidelines permit this. Do not recycle your used sharps disposal container.

Care of your Norditropin FlexPro Pen:

You must take care of your Norditropin FlexPro Pen:

  • Do not drop your Pen or knock it against hard surfaces. If you drop it or think that something is wrong with it, always screw on a new disposable needle and check the growth hormone flow (priming) before you inject.
  • Do not try to refill your Pen. It is prefilled.
  • Do not try to repair your Pen or pull it apart.
  • Do not expose your Pen to dust, dirt or any kind of liquid.
  • Do not try to wash, soak or lubricate your Pen. Clean the Norditropin FlexPro Pen with a mild detergent on a moistened cloth.
  • Always keep your Pen and needles out of reach of others, especially children.

  • If the Pen contains less than 8 mg, turn the dose selector until it stops. The number that lines up with the pointer shows how many mg is left in the Pen.
  • You cannot set a dose higher than the number of mg left in the Pen.
  • If there is not enough Norditropin left in the Pen to deliver your full dose, use a new Norditropin FlexPro Pen to inject the remaining amount of your dose or contact your healthcare provider.
  • Remember to subtract the dose already received. For example, if the dose is 0.6 mg and you can only set the dose selector to 0.3 mg, you should inject another 0.3 mg with a new Norditropin FlexPro Pen. See Figure L.

Important:

  • Never use the Pen clicks to count the number of mg you select. Only the display window and pointer will show the exact number.
  • Never use the growth hormone scale to measure how much liquid to inject. Only the display window and pointer will show the exact number.

Step 5. Selecting the injection site and injecting the dose of Norditropin.

  • Change the injection site every day.
  • Select the injection site and wipe the skin with an alcohol swab as your healthcare provider showed you.
  • Insert the needle under the skin as your healthcare provider showed you. See Figure M.

Figure M

Insert the needle under the skin as your healthcare
provider showed you  - - Illustration

  • After inserting the needle into the skin, push and hold the dose button in as far as it will go to give the dose. Inject until the “0” in the display window lines up with the pointer. As you do this, you may hear or feel a firm click. See Figure M.
  • If you remove your finger from the dose button before the “0” is in the display window the full dose has not been received. Leave the needle in the skin and press and hold the dose button again until the “0” lines up with the pointer.

If the injection button cannot be pushed in completely or “0” does not appear in the display window, you did not receive the full dose. Call Novo Nordisk at 1-888-668-6444 for assistance. You may need a new Pen.

  • After the “0” in the display window lines up with the pointer, leave the needle under the skin for at least 6 seconds to make sure that you get your full dose. Let go of the dose button while you wait.

Important:

  • Always press the dose button to inject the dose. Turning the dose selector will not inject the dose.
  • Never touch the display window when you inject, as this can block the injection.
  • Carefully lift the pen to remove the needle from the skin. After that, you may see a drop of liquid at the needle tip. This is normal and does not affect the dose you received. See Figure N.

Figure N

Carefully lift the pen to remove the needle from the
skin  - - Illustration

Step 6. What to do after the injection is completed.

  • Do not recap the needle. Recapping a needle can lead to a needle stick injury. Remove the needle from the Pen after each injection.
  • Carefully remove the needle from the Pen by turning the needle in a counterclockwise direction. See Figure O.

Figure O

Carefully remove the needle from the Pen by turning the
needle  - - Illustration

  • Put the Pen cap back on.
  • If there is medicine left in the Pen, store the Pen as directed in the Patient Information that comes with this Pen.
  • If the Pen is empty, throw the Pen away as directed below. Put your used needles and Pen in a FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles and Pens in your household trash.
  • If you do not have a FDA-cleared sharps disposal container, you may use a household container that is:
    • made of a heavy-duty plastic,
    • can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out,
    • upright and stable during use,
    • leak-resistant, and
    • properly labeled to warn of hazardous waste inside the container.
  • When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used needles and Pens. For more information about safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA's website at: http://www.fda.gov/safesharpsdisposal.
  • Do not dispose of your used sharps disposal container in your household trash unless your community guidelines permit this. Do not recycle your used sharps disposal container.

If a drop of liquid still does not appear at the needle tip after repeating Step 3 and changing the needle, call Novo Nordisk at 1-888-668-6444 for assistance.

Step 4. Selecting the correct dose of Norditropin:

Use the dose selector on your Pen to make sure you have the exact dose selected. Your dose will be in a certain number of mg (milligrams).

To start, check that the dose pointer on the Pen is set at “0”.

Select the dose you need by turning the dose selector clockwise. If you go beyond your dose, turn the dose selector counterclockwise until the right number of mg lines up with the dose pointer. See figure R. Dose selector

Figure R

Select the dose you need by
turning the dose selector clockwise   - - Illustration

To guide you, the dose selector click sound is different when turned clockwise (softer click) or counterclockwise (louder click). You will hear a click for every single unit dialed.

When dialing counterclockwise, be careful not to press the dose button as liquid will come out.

You can use the growth hormone scale on the side of the Pen to see approximately how much growth hormone is left in the Pen. You can also use the dose selector to see exactly how much growth hormone is left in the Pen.

If the Pen contains less than 2 mg, 4 mg, or 8 mg (depending on whether you use a 5 mg, 10 mg, or 15 mg Pen), turn the dose selector until it stops. The number that lines up with the dose pointer shows how many mg are left in the Pen. You cannot set a dose higher than the number of mg left in the Pen.

If there is not enough Norditropin left in the Pen for your full dose, use a new Norditropin FlexPro Pen to inject the remaining amount of your dose or contact your healthcare provider.

Remember to subtract the dose already received. For example, if the dose is 0.7 mg and you can only set the dose selector to 0.35 mg, you should inject another 0.35 mg with a new Norditropin FlexPro Pen.

Important:

Do not use the Pen clicks to count the number of mg you select. Only the display window and dose pointer will show the exact number.

Do not use the growth hormone scale to measure how much liquid to inject. Only the display window and dose pointer will show the exact number.

Step 5. Selecting your injection site and injecting the dose of Norditropin:

Change your injection site every day. Select the injection site and wipe your skin with an alcohol swab as your healthcare provider showed you.

Norditropin can be injected under your skin (subcutaneously) of your hips, stomach area (abdomen), upper legs (thighs), upper arms, or as otherwise instructed by your healthcare provider. See Figure S.
