Clinical Trial Summary

The primary purpose of Study INZ701-104 (the ENERGY study) is to assess the safety and tolerability of INZ-701 in infants with ENPP1 Deficiency or with ABCC6 Deficiency.


Clinical Trial Description

INZ-701 is an ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) enzyme replacement therapy in development for the treatment of the ultra-rare genetic disorder, ENPP1 Deficiency or with ABCC6 Deficiency. Study INZ701-104 (the ENERGY study) is a Phase 1b, open-label study to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of INZ-701 in infant study participants with ENPP1 Deficiency or ABCC6 Deficiency. The study will consist of up to a 60-day Screening Period, a 52-week Treatment Period during which study participants will receive INZ-701, an Extension Period during which participants may continue to receive INZ-701 until it is commercially available in the country where the participant resides, or until an alternative study of INZ-701 is available, and an End of Treatment (EOT) visit 30 days after the last dose of INZ-701. Upon treatment discontinuation, participants will continue to be followed for their ongoing disposition for survival outcome at least quarterly through the end of the study. ;
