Details and patient eligibility

About

The purpose of this study (Study INZ701-304 [ADAPT]) is to assess the long-term safety of INZ-701 in patients with ENPP1 Deficiency or ABCC6 Deficiency who have received INZ-701 in an existing clinical study and choose to continue dosing for the potential treatment of their condition.

Full description

The investigational product INZ-701 is being developed as a therapeutic protein for the treatment of ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) Deficiency and adenosine triphosphate (ATP)-binding cassette subfamily C member 6 (ABCC6) Deficiency. INZ-701 is a recombinant fusion protein that contains the extracellular domains of human ENPP1 coupled with an Fc fragment from an immunoglobulin (Ig) G1 antibody.

The ADAPT Study (INZ701-304) is an open-label study to assess the long-term safety of INZ-701 in patients with ENPP1 Deficiency or ABCC6 Deficiency who have received INZ-701 in an existing clinical study and choose to continue dosing for the potential treatment of their condition.

The study will consist of a 30-day Screening Period, followed by an open-label Treatment Period during which all participants will receive once-weekly subcutaneous (SC) doses of INZ-701 and continue with treatment until INZ-701 is commercially available in the country/region of the participant's residence or until Inozyme chooses to discontinue development of INZ-701. Participants will complete an End of Study (EOS) safety follow-up visit approximately 30 days after their last designated study visit assigned by the Investigator and/or Sponsor.

  7. In the opinion of the Investigator, able to complete all aspects of the study

Individuals who meet any of the following exclusion criteria will not be eligible to participate:

  1. In the opinion of the Investigator, presence of any clinically significant disease or laboratory abnormality not associated with ENPP1 Deficiency or ABCC6 Deficiency, that will preclude study participation and/or may confound interpretation of study results
  2. Known intolerance to INZ-701 or any of its excipients
  3. Concurrent participation in another interventional clinical study and/or has received an investigational drug other than INZ-701 within 5 half-lives or within 4 weeks prior to the first dose of INZ-701 in this study, whichever is longer, or use of an investigational device
  4. Pregnant, trying to become pregnant, or breastfeeding
