4 Contraindications

(revision underlined)

·       Hypersensitivity

SAIZEN  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 having acute critical illnesses should be weighed against the potential risk.

5.6 Severe Hypersensitivity

(New 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 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

 (New subsection added)

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 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

•     Lipoatrophy

•     Pancreatitis

•     Benzyl alcohol

6.3 Post-Marketing Experience

 (addition underlined)

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