Lanreotide Autogel Treatment of Patients With Congenital Hyperinsulinism of Infancy

Congenital Hyperinsulinism Clinical Trial

Official title: Treatment With Lanreotide Autogel (Somatostatin Analogue) in Patients With Congenital Hyperinsulinism of Infancy Already Treated With Somatostatin Analog by Pump

Status Completed

Clinical Trial Summary

The purpose of our study is to evaluate the efficacy and safety of Lanreotide Autogel in children with congenital hyperinsulinism already treated with Octreotide by pump.

Congenital hyperinsulinism is a genetic disorder characterized by inappropriate insulin secretion resulting in persistent hypoglycemia (low blood sugars. Patients exposed to recurrent hypoglycemic episodes are at increased risk of developmental disorders, so identification and prompt management of patients are essential. Many patients are treated with the somatostatin analog Octreotide which is administered by continuous infusion using a pump (we use an insulin pump). This treatment may pose a huge burden and be stressful for patients and families as it demands intensive daily care. In an effort to simplify the daily care of our patients and improve their quality of life we will study the efficacy and safety of Lanreotide Autogel - a long-acting somatostatin analog that can be administered by injection once a month

Clinical Trial Description

The purpose of our study is to evaluate the efficacy and safety of Lanreotide Autogel in children with CHI already treated with Octreotide by pump.

Patients and methods. Congenital hyperinsulinism (CH) is a genetic disorder characterized by dysregulated insulin secretion resulting in persistent hypoglycemia. Identification and prompt management of patients are essential, as patients exposed to recurrent hypoglycemic episodes are at increased risk of developmental disorders. Many patients are treated with the somatostatin analog Octreotide which is administered by continuous infusion using a pump. This treatment may pose a huge burden and be stressful for patients and families as it demands intensive daily care. In an effort to simplify the daily care of our patients and improve their quality of life we will study the efficacy and safety of Lanreotide Autogel(Lan-ATG)- a long-acting somatostatin analog that can be administered by injection once a month.

This trial will include children with CH, who are treated with Octreotide by pump. We believe that children older than 2 years old will benefit most from this therapy. At this age, some of the parents encounter technical problems with the pump, as the children are prone to play with the pump and take out the needles. It's also very difficult to place the children in day care, because they need continuous follow up.

The dose of Lan-ATG will be calculated according to the surface area of the patient. The dose used in adults is usually 60 mg and we will adapt the patient's dose according to the body surface area and also according to the daily dose of Octreotide used with the pump. The starting dose will be 40 mg/m².

The patients will be gradually weaned from the pump following the first injection of Lan-ATG (10% decrease every 3-4 days for a total of a month).

Every patient will serve as his/her own control.

The following examinations will be done in every child:

1. Continuous blood glucose monitoring during 72 hours with a glucosensor, to exclude asymptomatic hypoglycemia - once in 6 months.

2. Growth velocity every 3 months.

3. Bone age once a year.

4. Routine laboratory tests (biochemistry, CBC and thyroid function tests) every six months.

5. Biliary US once in 6 months. During the follow up we will try to expand the distance between injections, based on our knowledge that most of the patients with CH are known to enter remission after the age of 4-5 years. ;
