About Ngenla

Overview

Ngenla contains somatrogon-ghla, a human growth hormone analog. It is used to treat children aged 3 years and older who have growth failure because their bodies do not produce enough growth hormone. It works by binding to growth hormone receptors and increasing levels of insulin-like growth factor 1 (IGF-1), which helps stimulate growth.

What it treats

Growth failure in children aged 3 years and older due to insufficient production of the body’s own growth hormone.

Safety information

Side effects

Common side effects reported in at least 5% of patients treated with Ngenla include injection-site reactions, nose and throat inflammation, headache, fever, anemia, cough, vomiting, an underactive thyroid, abdominal pain, rash and throat pain. Seek prompt medical attention if an allergic reaction occurs, as severe reactions are possible. Contact a doctor about a new limp, persistent hip or knee pain, or persistent severe abdominal pain. These may indicate a problem with the growth plate in the hip or inflammation of the pancreas. Other serious risks include increased pressure inside the skull, fluid retention, reduced insulin sensitivity and diabetes, low cortisol levels, and new or worsening thyroid problems. Existing scoliosis may worsen. Repeated injections in the same location can cause loss of fat under the skin; rotate injection sites. The label also warns about tumor progression or recurrence. An increased risk of a second tumor has been reported in childhood cancer survivors treated with somatropin, particularly tumors of the membranes surrounding the brain in those who received radiation to the head. It also lists increased mortality in patients with acute critical illness and sudden death in children with Prader-Willi syndrome.

When to call your doctor

• Seek immediate medical attention if you have an allergic reaction. • Seek prompt medical attention for severe stomach pain that does not go away. • Contact your doctor promptly if you develop a limp or persistent hip or knee pain.

If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.

Before taking this medicine

Do not use Ngenla if you: • Are critically ill following open-heart surgery, abdominal surgery or multiple accidental injuries, or have acute respiratory failure. • Are allergic to somatrogon-ghla or any other ingredient in Ngenla. • Have closed growth plates. • Have active cancer. • Have active proliferative or severe non-proliferative diabetic retinopathy. • Have Prader-Willi syndrome and are severely obese, have a history of upper airway obstruction or sleep apnea, or have severe breathing impairment. Extra caution and monitoring are needed if you have a pre-existing tumor, a history of childhood cancer, diabetes or risk factors for diabetes, low adrenal hormone levels, an underactive thyroid or scoliosis. A higher risk of a second tumor has been reported in childhood cancer survivors treated with somatropin, particularly meningiomas in those who received radiation to the head. Ngenla may reduce insulin sensitivity, cause fluid retention, lower cortisol levels or reveal or worsen an underactive thyroid. Blood glucose and thyroid function should be monitored, with cortisol monitoring where appropriate. Eye examinations are needed before and during treatment to check for swelling of the optic nerve. Any existing swelling must be investigated and its cause treated before starting; if it develops during treatment, Ngenla must be stopped. Seek prompt medical attention for an allergic reaction. Report a new limp, persistent hip or knee pain, or persistent severe abdominal pain, as these may indicate a hip growth-plate problem or pancreatitis. Rotate injection sites to reduce the risk of local loss of fat tissue.

Interactions

Tell your doctor if you take any of the following: • Glucocorticoids, including cortisone acetate or prednisone. Starting Ngenla may lower cortisol levels, so your doctor may need to adjust replacement treatment for low adrenal hormone levels. Glucocorticoid treatment above normal replacement levels may also reduce Ngenla’s growth-promoting effects in children. • Medicines processed by liver enzymes called CYP450. Ngenla may change how quickly these medicines are cleared from the body, so careful monitoring is advised. • Oral estrogen replacement. This may reduce the IGF-1 response to Ngenla, and your doctor may need to adjust treatment. • Insulin or other diabetes medicines. Ngenla may reduce insulin sensitivity, and your doctor may need to adjust your diabetes treatment.
