  • Both due to recurrence of medulloblastoma.

  • All serious adverse events considered related to growth hormone treatment occurred in single patients except for medulloblastoma recurrence in 2 patients (both with organic growth hormone deficiency) and adenoidal hypertrophy in 2 patients (1 with organic growth hormone deficiency, 1 with Turner syndrome). Other serious adverse events reported as related to growth hormone treatment were meningioma, neoplasm progression, aortic valve incompetence, rectal hemorrhage, edema, death, parotitis, upper limb fracture, type 1 diabetes mellitus, optic glioma, anaplastic astrocytoma, adrenal neoplasm, increased intracranial pressure, ischemic stroke, tonsillar hypertrophy, sleep apnea syndrome, scoliosis surgery, meningioma surgery, adenoidectomy and angiodysplasia; some patients experienced more than 1 event.

  • § Any treatment-emergent adverse event irrespective of relatedness with frequency of 5% or more among all patients.

  • Any treatment-emergent adverse event considered related with frequency greater than 0.5% among all patients.
