Study Summary

This trial tests if a drug can help treat a rare disorder in children, focusing on safety & efficacy.

Who is the study for?
This trial is for children with ENPP1 Deficiency, showing specific bone abnormalities and growth plate activity. They must be between 1-12 years old, not pregnant or breastfeeding, willing to use contraception if applicable, and have certain vitamin D levels. Those who've had recent surgery or used certain medications like systemic corticosteroids are excluded.Check my eligibility
What is being tested?
The ENERGY 3 Study tests the safety and effectiveness of INZ-701 compared to conventional therapy in treating skeletal issues caused by ENPP1 Deficiency in children. Participants will either receive INZ-701 or stick with standard treatments to see which works better.See study design
What are the potential side effects?
While the side effects of INZ-701 are not detailed here, they may include reactions similar to other drugs targeting bone metabolism such as gastrointestinal symptoms, skin reactions, or changes in blood chemistry.
