Summary

This study tests a new drug called ALXN1850 in children aged 2 to 12 with hypophosphatasia, a rare genetic condition that weakens bones. The trial compares the drug to a placebo to see if it improves bone health and movement. About 30 children who have not received prior treatment for this condition will take part.

What this could lead to

If it works, this could provide a new treatment option for children with hypophosphatasia, improving bone strength and physical function.

What could go wrong
