Summary

This trial is testing the role of the drug pegvisomant in children and adolescents with gigantism. Eligible participants must be aged 2-18, have GH excess, and be unresponsive or ineligible for current treatments. The study will last 60 weeks and include several visits with medical history and physical exams, questionnaires, heart and liver tests, and blood and urine tests. Participants will also have an MRI and hand X-ray at the baseline and 12-month visits.

Who is the study for?
This trial is for children and teens aged 2-18 with growth hormone excess, typically causing abnormal growth (gigantism), who haven't had success with standard treatments or can't use them. They must be willing to stop other GH treatments before starting the study drug, agree to certain birth control methods if applicable, have a local doctor for regular check-ups, and not have liver issues or current opioid use.
What is being tested?
The trial tests Pegvisomant's safety and effectiveness in managing excessive growth hormone in kids. Over 60 weeks, participants will visit at least three times for medical exams, questionnaires, heart/liver tests, MRI scans with dye injection, hand X-rays and learn to self-inject the drug daily at home.
What are the potential side effects?
Potential side effects of Pegvisomant may include reactions at the injection site like pain or swelling; changes in liver function; headaches; flu-like symptoms; nausea; potential interference with normal fat distribution.
