Hunter syndrome immune study pulled before it began

NCT ID NCT05494593

First seen Jan 04, 2026 · Last updated May 06, 2026 · Updated 24 times

Summary

This study aimed to see if a combination of immune-suppressing drugs could prevent the body from making antibodies that block the enzyme therapy ELAPRASE in boys with Hunter syndrome who had never been treated before. The plan was to give rituximab, methotrexate, and intravenous immunoglobulin alongside ELAPRASE for up to 104 weeks. However, the study was withdrawn before enrolling any participants, so no results are available.
