Warnings and Precautions
5.10 Slipped
Capital Femoral Epiphysis (SCFE) in Pediatric Patients
Additions and/or
revisions underlined:
SCFE
may occur more frequently in patients with endocrine disorders (including GHD
and TS) or in patients undergoing rapid growth. SCFE may lead to
osteonecrosis. Cases of SCFE with or without osteonecrosis have been reported
in pediatric patients with short stature receiving somatropin, including
NUTROPIN AQ. Any pediatric patient with the onset of a limp or complaints
of hip or knee pain during NUTROPIN AQ therapy should be evaluated
for SCFE and osteonecrosis and managed accordingly.

including NUTROPIN AQ: Slipped capital femoral epiphysis [children, see Warnings and Precautions (5.10)] and
osteonecrosis (children).

Contraindications
(revision underlined)
Hypersensitivity
Nutropin AQ 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.

Warnings and Precautions
5.13 Osteodystrophy in Pediatric Patients with
Chronic Kidney Disease
(addition underlined)
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.
5.1 Acute Critical Illness
(additions underlined)
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 . 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.
5.6 Severe Hypersensitivity
(New subsection added)
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.
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 previousl
diagnosed hypoadrenalism may require an increase in
their maintenance or stress doses following initiation of somatropin treatment.

6.3 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. The adverse events reported during post-marketing surveillance do not
differ from those listed/discussed above in children and adults.
Serious systemic hypersensitivity reactions
including anaphylactic reactions and angioedema have been reported with
postmarketing use of somatropin products.
Leukemia has been reported in a small number of GHD
children treated with somatropin, somatrem (methionylated rhGH) and GH of
pituitary origin. It is uncertain whether these cases of leukemia are related
to GH therapy, the pathology of GHD itself, or other associated treatments such
as radiation therapy. On the basis of current evidence, experts have not been
able to conclude that GH therapy per se was responsible for these cases of
leukemia. The risk for children with GHD, CKD, or TS, if any, remains to be
established.
The following additional adverse reactions have been
reported in GH-treated patients: gynecomastia (children), and pancreatitis.
