Summary

This trial is testing a new drug to treat secondary hyperparathyroidism (a condition caused by kidney disease) in children.

Who is the study for?
This trial is for children under 18 with chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPT), who are on hemodialysis. They must weigh at least 7 kg, have specific levels of parathyroid hormone and calcium, and not be due to vitamin D deficiency. Kids can't join if they've had certain cancers, used etelcalcetide recently, or are taking conflicting medications.
What is being tested?
The study tests Etelcalcetide's effectiveness in treating SHPT in kids with CKD on hemodialysis. It's a Phase 3 trial which means it’s closer to potentially being approved for general use if successful.
What are the potential side effects?
While the side effects aren't listed here, similar drugs often cause issues like low blood calcium levels, nausea, vomiting, muscle twitching or spasms. The exact side effects will be monitored throughout the trial.
