The ENERGY 3 Study: Evaluation of Efficacy and Safety of INZ-701 in Children With ENPP1 Deficiency

INZ-701 is an ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) enzyme replacement therapy (ERT) in development for the treatment of ENPP1 Deficiency, an ultra-rare genetic disorder with an incidence of 1 in 64,000 pregnancies. Study INZ701-106 (The ENERGY 3 Study) is a multi-center, randomized in a 2:1 ratio, controlled, open-label Phase 3 study to evaluate the efficacy and safety of INZ-701 in children with ENPP1 Deficiency. The study will consist of a Screening Period of up to 52 days (including a washout period of up to 7 days for prohibited medications post-Randomization) and a Randomized Treatment Period (INZ-701 or control) of 52 weeks, followed by an Open-label Extension Period during which all study participants may receive INZ-701, and an End of Study (EOS) Safety visit 30 days after the last dose of INZ-701.
