Calciphylaxis diagnosis, management and future directions: a comprehensive update on behalf of the European Renal Association CKD-MBD Working Group. (PubMed, Clin Kidney J) - "Recent investigational therapies, including SNF472 and INZ-701, target key calcification pathways and offer promise. Looking ahead, future research should prioritize the development and validation of diagnostic criteria, and prognostic tools integrating clinical risk factors with biomarkers. In addition, we propose the routine inclusion of patient-reported experience measures in calciphylaxis studies to better capture treatment impact in this vulnerable population."

Recombinant ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) decreases vascular calcification and prevents osteomalacia in a rat model of chronic kidney disease. (PubMed, JBMR Plus) - "Moreover, INZ-701 treatment significantly prevented the osteoid volume increase observed in vehicle-treated rats, addressing another critical clinical manifestation of CKD-MBD. These results underscore the potential of INZ-701 to reduce vascular calcification and bone mineralization abnormalities in CKD."

SEAPORT 1: An Open-label Study to Evaluate the Safety, Pharmacokinetics, and Pharmacodynamics of INZ-701 in Participants with ESKD Undergoing Hemodialysis: Interim Analysis (KIDNEY WEEK 2024) - "Median PPi at screening in 13 patients with ESKD on hemodialysis was substantially lower than what is reported in healthy volunteers (1002-2169 nM; n=10), which supports previous findings implicating PPi in the pathophysiology of ESKD. INZ-701 safety, tolerability, pharmacokinetics, and pharmacodynamics results will be presented."

Novel treatment for PXE: Recombinant ENPP1 enzyme therapy. (PubMed, Mol Ther) - "Recent studies demonstrated that INZ-701, a recombinant human ENPP1, the principal PPi-generating enzyme, restored plasma PPi levels and prevented ectopic calcification in the muzzle skin of an Abcc6-/- mouse model of PXE...When Abcc6-/- mice were injected weekly from 5 to 15 weeks of age, BL-1118 dose-dependently increased steady-state plasma ENPP1 activity and PPi levels and significantly reduced ectopic calcification in the muzzle skin and kidneys. These results suggest that BL-1118 is a promising enzyme therapy for PXE, a disease currently lacking preventive or therapeutic options."
