ENPP1 Deficiency Trial
Study Overview
The clinical trial for ENPP1 Deficiency will determine if a new medication, INZ-701, is suitable to treat those affected with the disease. Participants will be split into 3 groups. Each group will receive a different dose of INZ-701. INZ-701 is a subcutaneous injection (under the skin).
Researchers will monitor participants on increasing doses of INZ-701 to:
Understand the safety of the medication
Study how the medication is processed throughout the body
Study changes in PPi and other markers
For the extension period of the study, researchers will monitor participants on increasing doses of INZ-701 to evaluate skeletal, vascular, and physical function as well as outcomes reported by participants.
Subject participation consists of a screening period, a 32-day dose-evaluation period, and a 48-week extension period following completion of the dose-evaluation period.
