4 Contraindications

 (revision underlined)

Hypersensitivity

GENOTROPIN is contraindicated in patients with a known hypersensitivity to somatropin or any of its excipients. The 5 mg and 12 mg presentations of GENOTROPIN lyophilized powder contain m-cresol as a preservative. Systemic hypersensitivity reactions have been reported with post-marketing use of somatropin products.

5 Warnings and Precautions

5.6 Severe Hypersensitivity

(subsection added)

Serious systemic hypersensitivity reactions including anaphylactic reactions and angioedema have been reported with post-marketing 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.

5.7 Fluid Retention

(addition underlined)

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.

6 Adverse Reactions

(additions underlined)

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

 

·       Increased mortality in patients with acute critical illness

·       Fatalities in children with Prader-Willi syndrome        

·       Neoplasms

·       Glucose intolerance and diabetes mellitus

·       Intracranial hypertension

·       Severe hypersensitivity

·       Fluid retention

·       Hypoadrenalism

·       Hypothyroidism

·       Slipped capital femoral epiphysis in pediatric patients

·       Progression of preexisting scoliosis in pediatric patients

·       Otitis media and cardiovascular disorders in patients with Turner syndrome •

·       Lipoatrophy

·       Pancreatitis

6.2 Post-Marketing Experience

(additions underlined)

Because these adverse events 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.

5 Warnings and Precautions

Acute Critical Illness

  • 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 (41.9% vs. 19.3%) among somatropin-treated patients (doses 5.3–8 mg/day) compared to those receiving placebo. (This statement was previously in the Contraindications section under the subsection Acute Critical Illness)

Hypoadrenalism replaces Hypopituitarism

  • 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.

6 Adverse Reactions

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

  • Acute critical illness (addition)

  • Hypoadrenalism

  • Otitis media and cardiovascular disorders in Turner Syndrome

Post-Marketing Experience

  • The following serious adverse reactions have been observed with use of somatropin (including events observed in patients who received brands of somatropin other than Genotropin): acute critical illness, sudden death, intracranial tumors, central hypothyroidism, cardiovascular disorders, and pancreatitis.

  • Slipped capital femoral epiphysis and Legg-Calve-Perthes disease (osteonecrosis/avascular necrosis; occasionally associated with slipped capital femoral epiphysis) have been reported in children treated with growth hormone. Cases have been reported with Genotropin.

  • The following additional adverse reactions have been observed during the appropriate use of somatropin: headaches (children and adults), gynecomastia (children), and significant diabetic retinopathy.
