About
The purpose of this study is to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics PD) of multiple ascending doses of INZ-701, an ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) recombinant fusion protein, for the treatment of ABCC6 Deficiency. The goal of the study is to identify a dose regimen for further clinical development in the treatment of ABCC6 Deficiency.
Full description
INZ-701 is an ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) recombinant fusion protein in development for the treatment of ABCC6 Deficiency, a rare genetic disorder.
Study INZ701-201 is a Phase 1/2, multicenter, open-label, multiple ascending dose (MAD), dose-finding study followed by a long-term open-label Extension Period conducted in adults with ABCC6 Deficiency manifesting as Pseudoxanthoma elasticum (PXE). This study is designed to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of multiple ascending doses of INZ-701. The goal of the study is to identify a dose and dose schedule (number of doses per week) for further clinical development in ABCC6 Deficiency. No placebo will be used in this study.
Exploratory endpoints for the Extension Period of the study include evaluations of arterial and organ calcification, ophthalmologic, cardiac and renal parameters, and physical function as well as patient reported outcomes.
Subject participation consists of a Screening Period of up to 60 days, a 32-day Dose Evaluation Period, and an Extension Period during which subjects may continue to receive INZ-701 (with options for self-, caregiver-, or healthcare provider administration) until INZ-701 is approved and available in the country where the subject resides or until an alternative study for subjects to continue receiving study drug is available. During the Extension Period, follow-up visits will be conducted every 4 weeks until Week 48 of the Extension Period and then every 12 weeks (remote or in-clinic) until the subject leaves the study.
Subjects will complete a follow up visit 30 days after their last dose of INZ-701.
