Summary

This trial will test a new therapy for two rare genetic disorders that cause calcium buildup in arteries and bones.

Who is the study for?
Adults aged 18 to <65 with a clinical diagnosis of ENPP1 Deficiency, confirmed by genetic testing, can join this trial. They must be able to complete the study and provide medical records. Women who can have children and men must agree to use contraception during the study.
What is being tested?
The trial is testing multiple doses of INZ-701, an enzyme replacement therapy for treating ENPP1 Deficiency. It aims to determine the safety, how well it's tolerated, its effects on the body (PK/PD), and find a suitable dose for further studies.
What are the potential side effects?
Potential side effects are not explicitly listed but may include reactions related to immune response or infusion processes typical in enzyme replacement therapies such as allergic reactions, discomfort at injection site, fever, chills or nausea.

Trial Design

1Treatment groups
Experimental Treatment
Group I: INZ-701Experimental Treatment1 Intervention
The study design of the Dose Evaluation Period is a MAD 3 + 3 with 3 dose cohorts. Additional cohorts may be added to evaluate an intermediate dose and/or an alternative dosing regimen of an existing dose level. Based on nonclinical findings and nonclinical pharmacology modeling, the initial planned doses will be 0.2 mg/kg, 0.6 mg/kg, and 1.8 mg/kg all twice weekly, not to exceed 3.6 mg/kg weekly. During the Extension Period, visits will be every 4 weeks until Week 48 and then every 12 weeks until the subject leaves the study. Subjects will complete an End of Study (EOS) Visit (Safety Follow-up Visit) 30 days after their last dose of INZ-701 (greater than 5 half-lives of INZ-701) for all subjects.
