Nutropin Aq

Short Term

Short-term overdosage could lead initially to hypoglycemia and subsequently to hyperglycemia. Furthermore, overdose with somatropin is likely to cause fluid retention.

Long Term

Long-term overdosage could result in signs and symptoms of gigantism and/or acromegaly consistent with the known effects of excess growth hormone (GH) [See DOSAGE AND ADMINISTRATION].

Before you receive somatropin, tell your doctor about all your past and present medical conditions, especially allergies, trauma, surgery, diabetes, cancer, breathing problems, liver or kidney disease, scoliosis, high blood pressure, pancreas disorder, underactive thyroid, or a brain tumor.

Also tell your doctor about all other medications you use, especially steroids or diabetes medications. Your dosages of these medicines may need to be changed when you start using somatropin. Do not stop using a steroid suddenly or change any of your medication doses without your doctor's advice.

If you have Prader-Willi syndrome and are using somatropin, call your doctor promptly if you develop signs of lung or breathing problems such as shortness of breath, coughing, or new or increased snoring.

Call your doctor at once if you have sudden and severe pain in your upper stomach with nausea and vomiting, fast heartbeat, increased thirst or urination, weight loss, or vision changes and sudden, severe pain behind your eyes.

Before you receive somatropin, tell your doctor if you have ever had an allergic reaction to a growth hormone medicine, or to drug preservatives such as benzyl alcohol, metacresol or glycerin.

You should not use this medication if you are allergic to somatropin, or if you have:

• diabetic retinopathy (a serious eye condition caused by diabetes);
• cancer; or
• Prader-Willi syndrome and are also overweight or have sleep apnea or severe respiratory (lung) problems.

You should also not use somatropin if you have a serious medical condition after having:

• open heart surgery or stomach surgery;
• trauma or other medical emergency; or
• breathing problems (such as lung failure).

To make sure you can safely take somatropin, tell your doctor if you have any of these other conditions:

• liver disease;
• kidney disease (or if you are on dialysis);
• diabetes;
• a pituitary gland disorder;
• scoliosis;
• high blood pressure (hypertension);
• a pancreas disorder (especially in children);
• a history of cancer;
• carpal tunnel syndrome;
• underactive thyroid; or
• a brain tumor or lesion.

FDA pregnancy category B. Some brands of somatropin are not expected to harm an unborn baby, including Genotropin, Omnitrope, Saizen, Serostim, and Zorbtive.

FDA pregnancy category C. It is not known whether certain other brands of somatropin will harm an unborn baby, including Humatrope, Norditropin, Nutropin, and Tev-tropin.

Tell your doctor if you are pregnant or plan to become pregnant while using this medication.

It is not known whether somatropin passes into breast milk or if it could harm a nursing baby. Do not use somatropin without telling your doctor if you are breast-feeding a baby.

Pediatric Patients

Growth Hormone Deficiency (GHD) - Nutropin AQ® is indicated for the treatment of pediatric patients who have growth failure due to inadequate secretion of endogenous growth hormone (GH).

Growth Failure Secondary to Chronic Kidney Disease (CKD) - Nutropin AQ is indicated for the treatment of growth failure associated with CKD up to the time of renal transplantation. Nutropin AQ therapy should be used in conjunction with optimal management of CKD.

Idiopathic Short Stature (ISS) - Nutropin AQ is indicated for the treatment of ISS, also called non-GHD short stature, defined by height SDS ≤ –2.25, and associated with growth rates unlikely to permit attainment of adult height in the normal range, in pediatric patients whose epiphyses are not closed and for whom diagnostic evaluation excludes other causes associated with short stature that should be observed or treated by other means.

Short Stature Associated with Turner Syndrome (TS) - Nutropin AQ is indicated for the treatment of short stature associated with TS.

Adult Patients

Nutropin AQ is indicated for the replacement of endogenous GH in adults with GHD who meet either of the following two criteria:

Adult Onset: Patients who have GHD, either alone or associated with multiple hormone deficiencies (hypopituitarism), as a result of pituitary disease, hypothalamic disease, surgery, radiation therapy, or trauma; or

Childhood Onset: Patients who were GH deficient during childhood as a result of congenital, genetic, acquired, or idiopathic causes.

Patients who were treated with somatropin for GHD in childhood and whose epiphyses are closed should be reevaluated before continuation of somatropin therapy at the reduced dose level recommended for GH deficient adults. According to current standards, confirmation of the diagnosis of adult GHD in both groups involves an appropriate GH provocative test with two exceptions: (1) patients with multiple pituitary hormone deficiencies due to organic disease; and (2) patients with congenital/genetic GHD.

Nutropin AQ is available in the following pen cartridge and NuSpin forms:

• Pen Cartridge: 10 mg/2 mL (yellow color band), and 20 mg/2 mL (purple color band)
• NuSpin: 5 mg/2 mL (clear device), 10 mg/2 mL (green device), and 20 mg/2 mL (blue device)

Acute Critical Illness

Increased mortality in patients with acute critical illnesses 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-GHD 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 somatropin treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropin in patients having acute critical illnesses should be weighed against the potential risk.

Prader-Willi Syndrome (PWS) in Children

There have been reports of fatalities after initiating therapy with somatropin in pediatric patients with PWS 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 PWS syndrome should be evaluated for signs of upper airway obstruction and sleep apnea before initiation of treatment with somatropin. If during treatment with somatropin, 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 PWS treated with somatropin 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)]. Nutropin AQ is not indicated for the treatment of pediatric patients who have growth failure due to genetically confirmed PWS.

Neoplasms

In childhood cancer survivors who were treated with radiation to the brain/head for their first neoplasm and who developed subsequent GHD and were treated with somatropin, an increased risk of a second neoplasm has been reported. 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 [see Contraindications (4)]. Monitor all patients with a history of GHD secondary to an intracranial neoplasm routinely while on somatropin therapy for progression or recurrence of the tumor.

Because children with certain rare genetic causes of short stature have an increased risk of developing malignancies, practitioners should thoroughly consider the risks and benefits of starting somatropin in these patients. If treatment with somatropin is initiated, these patients should be carefully monitored for development of neoplasms.

Monitor patients on somatropin therapy carefully for increased growth, or potential malignant changes, of preexisting nevi.

Glucose Intolerance and Diabetes Mellitus

Treatment with somatropin may decrease insulin sensitivity, particularly at higher doses in susceptible patients. As a result, previously undiagnosed impaired glucose tolerance (IGT) and overt diabetes mellitus may be unmasked during somatropin treatment, and new onset type 2 diabetes mellitus has been reported in patients taking somatropin. Therefore, glucose levels should be monitored periodically in all patients treated with somatropin, especially in those with risk factors for diabetes, such as obesity, Turner syndrome (TS), or a family history of diabetes mellitus. Patients with preexisting type 1 or type 2 diabetes mellitus or IGT should be monitored closely during somatropin therapy. The doses of antihyperglycemic drugs (i.e. insulin or oral/injectable agents) may require adjustment when somatropin therapy is instituted in these patients.

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 somatropin to exclude preexisting papilledema, and periodically during the course of somatropin therapy. If papilledema is observed by funduscopy during somatropin treatment, treatment should be stopped. If somatropin-induced IH is diagnosed, treatment with somatropin can be restarted at a lower dose after IH-associated signs and symptoms have resolved. Patients with TS, chronic kidney disease (CKD), and PWS may be at increased risk for the development of IH.

Severe Hypersensitivity

Serious systemic hypersensitivity reactions including anaphylactic reaction 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.

Fluid Retention

Fluid retention during somatropin replacement therapy in adults may 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 somatropin treatment [see Section 7.1, 11-β Hydroxysteroid Dehydrogenase Type 1].

Hypothyroidism

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

Slipped Capital Femoral Epiphysis (SCFE) in Pediatric Patients

SCFE may occur more frequently in patients with endocrine disorders (including GHD and TS) or in patients undergoing rapid growth. Any pediatric patient with the onset of a limp or complaints of hip or knee pain during somatropin therapy should be carefully evaluated.

Progression of Preexisting Scoliosis in Pediatric Patients

Progression of scoliosis can occur in patients who experience rapid growth. Because somatropin increases growth rate, patients with a history of scoliosis who are treated with somatropin should be monitored for progression of scoliosis. However, somatropin has not been shown to increase the occurrence of scoliosis. Skeletal abnormalities including scoliosis are commonly seen in untreated TS patients. Scoliosis is also commonly seen in untreated patients with PWS. Physicians should be alert to these abnormalities, which may manifest during somatropin therapy.

Otitis Media and Cardiovascular Disorders in Patients with Turner Syndrome

Patients with TS should be evaluated carefully for otitis media and other ear disorders, as these patients have an increased risk of ear and hearing disorders. Somatropin treatment may increase the occurrence of otitis media in patients with TS. In addition, patients with TS should be monitored closely for cardiovascular disorders (e.g., hypertension, aortic aneurysm or dissection, stroke) as these patients are also at increased risk for these conditions.

Osteodystrophy in Pediatric Patients with Chronic Kidney Disease

Children with growth failure secondary to CKD should be examined periodically for evidence of progression of renal osteodystrophy. SCFE or avascular necrosis of the femoral head may be seen in children with advanced renal osteodystrophy, and it is uncertain whether these problems are affected by somatropin therapy. X-rays of the hip should be obtained prior to initiating somatropin therapy in CKD patients and physicians and parents should be alert to the development of a limp or complaints of hip or knee pain in these patients treated with Nutropin AQ. No studies have been completed evaluating Nutropin AQ therapy in patients who have received renal transplants. Currently, treatment of patients with functioning renal allografts is not indicated.

Lipoatrophy

When somatropin is administered subcutaneously at the same site over a long period of time, tissue atrophy may result. This can be avoided by rotating the injection site [see Dosage and Administration (2.3)].

Laboratory Tests

Serum levels of inorganic phosphorus, alkaline phosphatase, and parathyroid hormone (PTH), and IGF-1 may increase during somatropin therapy.

Pancreatitis

Cases of pancreatitis have been reported rarely in children and adults receiving somatropin treatment, with some evidence supporting a greater risk in children compared with adults. Published literature indicates that girls who have TS may be at greater risk than other somatropin-treated children. Pancreatitis should be considered in any somatropin–treated patient, especially a child, who develops persistent severe abdominal pain.

11 β-Hydroxysteroid Dehydrogenase Type 1 (11βHSD-1)

The microsomal enzyme 11βHSD-1 is required for conversion of cortisone to its active metabolite, cortisol, in hepatic and adipose tissue. Growth hormone (GH) and somatropin inhibit 11βHSD-1. Consequently, individuals with untreated GH deficiency have relative increases in 11βHSD-1 and serum cortisol. Introduction of somatropin treatment may result in inhibition of 11βHSD-1 and reduced serum cortisol concentrations. As a consequence, previously undiagnosed central (secondary) hypoadrenalism may be unmasked and glucocorticoid replacement may be required in patients treated with somatropin. In addition, patients treated with glucocorticoid replacement for previously diagnosed hypoadrenalism may require an increase in their maintenance or stress doses following initiation of somatropin treatment; this may be especially true for patients treated with cortisone acetate and prednisone 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

Pharmacologic glucocorticoid therapy and supraphysiologic glucocorticoid treatment may attenuate the growth-promoting effects of somatropin in children. Therefore, glucocorticoid replacement therapy should be carefully adjusted in children with concomitant GH and glucocorticoid deficiency to avoid both hypoadrenalism and an inhibitory effect on growth.

The use of Nutropin AQ in patients with Chronic Kidney Disease (CKD) requiring glucocorticoid therapy has not been evaluated. Concomitant glucocorticoid therapy may inhibit the growth promoting effect of Nutropin AQ. Therefore, if glucocorticoid replacement is required for CKD, the glucocorticoid dose should be carefully adjusted to avoid an inhibitory effect on growth. In the clinical trials there was no evidence of drug interactions with Nutropin and commonly used drugs used in the management of CKD.

Cytochrome P450 (CYP450)-Metabolized Drugs

Limited published data indicate that somatropin treatment increases CYP450-mediated antipyrine clearance in man. These data suggest that somatropin administration may alter the clearance of compounds known to be metabolized by CYP450 liver enzymes (e.g., corticosteroids, sex steroids, anticonvulsants, cyclosporine). Careful monitoring is advisable when somatropin is administered in combination with other drugs known to be metabolized by CYP450 liver enzymes. However, formal drug interaction studies have not been conducted.

Oral Estrogen

Because oral estrogens may reduce insulin-like growth factor (IGF-1) response to somatropin treatment, girls and women receiving oral estrogen replacement may require greater somatropin dosages [see Dosage and Administration (2.2)].

Insulin and/or Oral/Injectable Hypoglycemic Agents

In patients with diabetes mellitus requiring drug therapy, the dose of insulin and/or oral/injectable hypoglycemic agents may require adjustment when somatropin therapy is initiated [see Warnings and Precautions (5.4)].

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity, mutagenicity, and reproduction studies have not been conducted with Nutropin AQ.
