Official Title: Replace Sandostatine® in Three Daily Subcutaneous Injections by a Single Intramuscular Injection of Sandostatine® LP Per Month in Patients With a Diffuse Form of Hyperinsulinism

Brief Summary: To replace Sandostatine® in three daily subcutaneous injections by a single intramuscular injection of Sandostatine® LP per month in patients with a diffuse form of hyperinsulinism.

Detailed Summary:

Persistent hyperinsulinemic hypoglycemias of infancy (HI) are characterized by an inappropriate secretion of insulin responsible for profound hypoglycemias which require aggressive treatment to prevent severe and irreversible brain damage.

Thanks to the complementarity and to the synergy between paediatricians, paediatric surgeons, radiologists, pathologists and geneticists, an important stage was reached: the recognition of two clinically similar forms of HI but requiring a radically different treatment: a diffuse form and a focal form in the pancreas.

The medical treatment is based on proglycem, or diazoxide, then octreotide (Sandostatine ®, Novartis) with a dose of 10 to 50 µg/Kg/jour divided to three subcutaneous injections. Most neonates are resistant to diazoxide and side effects are observed (important edema and hypertrichosis). The Sandostatine® is a much more effective treatment, unfortunately with a short half-life and painful injections. In the cases of resistance to the medical treatment, the distinction of the two forms is essential to guide the surgical treatment : partial pancreatectomy in the focal forms, curing definitively hypoglycemia; subtotal pancreatectomy in the diffuse forms resisting to the medical treatment, leading to a diabetes and a pancreatic exocrine insufficiency. Also, the medical treatment is essential in the case of the diffuse forms to avoid a subtotal pancreatectomy. Mutations in two genes encoding the potassium channels, SUR1 and KIR6.2, are responsible for hyperinsulinism resistant to diazoxide.

The Sandostatine® marketed by Novartis exists in two forms, a "rapid" form and a "retarded liberation form". These two molecules have been approved in the treatment of adults in the following indications:
