5 Warnings and Precautions

5.10 Slipped Capital Femoral Epiphysis in Pediatric Patients

Additions and/or revisions underlined:

Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders (including GHD and Turner Syndrome) or in patients undergoing rapid growth. Slipped capital femoral epiphysis may lead to osteonecrosis. Cases of slipped capital femoral epiphysis with or without osteonecrosis have been reported in pediatric patients with short stature receiving somatropin. Any pediatric patient with the onset of a limp or complaints of hip or knee pain during

OMNITROPE therapy should be evaluated for slipped capital femoral epiphysis and osteonecrosis and managed accordingly.

6 Adverse Reactions

6.2 Postmarketing Experience

Additions and/or revisions underlined:

The following adverse reactions have been identified during post approval use of somatropin or OMNITROPE. 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. The adverse events reported during postmarketing surveillance do not differ from those listed/discussed above in Sections 6.1 and 6.2 in children and adults.

. . .

The following additional adverse reactions have been observed during the use of somatropin: headaches (children and adults), gynecomastia (children), osteonecrosis (children), and pancreatitis (children and adults) [see Warnings and Precautions (5.16)].

4 Contraindications

•         Acute Critical Illness

 (addition underlined)

Treatment with pharmacologic amounts of somatropin is contraindicated 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.

•         Hypersensitivity

 (revision underlined)

Omnitrope is contraindicated in patients with a known hypersensitivity to somatropin or any of its excipients. Systemic hypersensitivity reactions have been reported with postmarketing use of somatropin products.

5 Warnings and Precautions

5.1 Acute Critical Illness

(additions  underlined)

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 . 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 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 experiencing acute critical illnesses should be weighed against the potential risk.

5.6 Hypersensitivity

(subsection added)

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.

5.7 Fluid Retention

(additions  underlined)

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.

5.8 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.

6 Adverse Reactions

 (additions underlined)

The following important adverse reactions •area also described elsewhere in labeling:

.   Increased mortality in patients with acute critical illness

·       Fatalities in children with Prader-Willi Syndrome

·       Neoplasm

·       Glucose intolerance and diabetes mellitus

·       Severe hypersensitivity

·       Fluid retention

·       Hypoadrenalism

·       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

·       Benzyl Alcohol

6.2 Post-Marketing Experience

 (addition underlined)

Serious systemic hypersensitivity reactions including anaphylactic reactions and angioedema have been reported with postmarketing use of somatropin products.
