Acromegaly

Active Ingredient: Pegvisomant

Indication for Pegvisomant

Population group: only adults (18 - 65 years old)

Treatment of adult patients with acromegaly who have had an inadequate response to surgery and/or radiation therapy and in whom an appropriate medical treatment with somatostatin analogues did not normalize IGF-I concentrations or was not tolerated.

For this indication, competent medicine agencies globally authorize below treatments:

10-80 mg once a day

Route of admnistration

Subcutaneous

Defined daily dose

10 - 30 mg

Dosage regimen

From 10 To 30 mg once every day

Loading dose

80 mg

Detailed description

A loading dose of 80 mg pegvisomant should be administered subcutaneously under medical supervision. Following this, pegvisomant 10 mg reconstituted in 1 ml of solvent should be administered once daily as a subcutaneous injection.

Dose adjustments should be based on serum IGF-I levels. Serum IGF-I concentrations should be measured every four to six weeks and appropriate dose adjustments made in increments of 5 mg/day in order to maintain the serum IGF-I concentration within the age-adjusted normal range and to maintain an optimal therapeutic response.

The maximum dose should not exceed 30 mg/day.

Dosage considerations

The site of injection should be rotated daily to help prevent lipohypertrophy.

Active ingredient

Pegvisomant

Pegvisomant is an analogue of human growth hormone that has been genetically modified to be a growth hormone receptor antagonist for the treatment of adult patients with acromegaly. Pegvisomant is highly selective for the GH receptor, and does not cross-react with other cytokine receptors, including prolactin.
