Severe systemic hypersensitivity reactions including anaphylaxis and angioedema have been reported with somatropin. Inform patients and/or caregivers that such reactions are possible and that prompt medical attention should be sought if an allergic reaction occurs. NGENLA is contraindicated in patients with known hypersensitivity to somatrogon-ghla or any excipients in NGENLA [see Contraindications (4)].
There is an increased risk of malignancy progression with somatropin treatment in patients with active malignancy [see Contraindications (4)]. Any preexisting malignancy should be inactive, and its treatment should be completed prior to instituting therapy with NGENLA. Discontinue NGENLA if there is evidence of recurrent malignancy.
Risk of Second Neoplasm in Pediatric Patients
In childhood cancer survivors, who were treated with radiation to the brain/head for their first neoplasm and who developed subsequent GHD and were treated with somatropin, an increased risk of a second neoplasm has been reported. Intracranial tumors, in particular meningiomas, were the most common of these second neoplasms. Monitor all patients with a history of GHD secondary to an intracranial neoplasm while on NGENLA therapy for progression or recurrence of the tumor.
New Malignancy During Treatment
Because children with certain rare genetic causes of short stature have an increased risk of developing malignancies, thoroughly consider the risks and benefits of starting NGENLA in these patients. If treatment with NGENLA is initiated, carefully monitor these patients for development of neoplasms.
Monitor patients on NGENLA therapy carefully for increased growth or potential malignant changes of preexisting nevi. Advise patients and/or caregivers to report marked changes in behavior, onset of headaches, vision disturbances and/or changes in skin pigmentation or changes in the appearance of preexisting nevi.
