Session Time: 10:00 a.m. PT
Presenting Author: Asghar Chaudhry, M.D., of South Florida Nephrology Research

About Calciphylaxis and the Implications of the PPi-Adenosine Pathway

Calciphylaxis (also known as calcific uremic arteriolopathy, or CUA) is a rare disorder with a high mortality rate that predominantly affects patients with ESKD. The disease is associated with low levels of inorganic pyrophosphate (PPi) and is characterized by pathologic mineralization (i.e., calcification) and intimal proliferation (the overgrowth of smooth muscle cells inside blood vessels) of the vasculature in the skin and fatty tissue. This leads to poor blood flow, blood clots, painful skin ulcers, serious infections, and often death, with a reported one-year survival rate of approximately 50%. Currently, there are no approved therapies for calciphylaxis. The estimated incidence of calciphylaxis is approximately 3.5 per 1,000 patients with ESKD with approximately 5,000 new patients presenting annually across major addressable markets.

The PPi-Adenosine Pathway plays a critical role in regulating both pathologic mineralization and intimal proliferation, with two key enzymes within this pathway, ENPP1 and CD73 generating PPi and adenosine, respectively. Recent genetic research has shown that polymorphisms in the ENPP1 and CD73 genes have been linked to an increased risk of complications in calciphylaxis.

INZ-701 is designed to restore PPi levels and increase adenosine production, addressing both key elements of the PPi-Adenosine Pathway. By normalizing these processes, INZ-701 has the potential to prevent the progression of calciphylaxis, offering a promising therapeutic solution for this high-risk and underserved patient population.

About Inozyme Pharma

Inozyme Pharma is a pioneering clinical-stage biopharmaceutical company dedicated to developing innovative therapeutics for rare diseases that affect bone health and blood vessel function. We are experts in the PPi-Adenosine Pathway, where the ENPP1 enzyme generates inorganic pyrophosphate (PPi), which regulates mineralization, and adenosine, which controls intimal proliferation (the overgrowth of smooth muscle cells inside blood vessels). Disruptions in this pathway impact the levels of these molecules, leading to severe musculoskeletal, cardiovascular, and neurological conditions, including ENPP1 Deficiency, ABCC6 Deficiency, calciphylaxis, and ossification of the posterior longitudinal ligament (OPLL).

Our lead candidate, INZ-701, is an ENPP1 Fc fusion protein enzyme replacement therapy (ERT) designed to increase PPi and adenosine, enabling the potential treatment of multiple diseases caused by deficiencies in these molecules. It is currently in clinical development for the treatment of ENPP1 Deficiency, ABCC6 Deficiency, and calciphylaxis. By targeting the PPi-Adenosine Pathway, INZ-701 aims to correct pathological mineralization and intimal proliferation, addressing the significant morbidity and mortality in these devastating diseases.
