Summary

This trial is testing a new drug for hemophilia in children. The goal is to see if it is safe and effective.

Who is the study for?
This trial is for male children aged 1 to less than 12 with severe hemophilia A or B. They must have a history of inhibitor antibodies and meet specific blood test criteria. Participants need good vein access for blood draws, weigh between 8 to <45 kg, and be able to follow the study plan with parental consent.
What is being tested?
The trial is testing appropriate dose levels of Fitusiran in young boys with severe hemophilia A or B. It aims to confirm dosing, assess safety and tolerability, and measure how much drug stays in the bloodstream over time.
What are the potential side effects?
While not explicitly listed here, potential side effects may include reactions at injection sites, possible liver issues due to altered clotting factor production, allergic responses, or other unforeseen complications related to Fitusiran.
