Calciphylaxis Market

• The calciphylaxis market is projected to maintain a steady Compound Annual Growth Rate (CAGR) from 2025 to 2034. This growth is driven by increasing disease recognition, a growing end-stage renal disease (ESRD) population, increased clinical awareness, increased dialysis use, and ongoing research into targeted therapeutic options for this rare but serious condition. 
• As per secondary research, the incidence of calciphylaxis among dialysis patients is estimated between 0.04% and 4%, with trends indicating an upward trajectory in recent years.
• Calciphylaxis affects an estimated 1–35 per 10,000 dialysis patients annually, though cases are likely underreported due to limited awareness. Key risk factors include hemodialysis, female sex, obesity, diabetes, electrolyte imbalances, autoimmune diseases, hypoalbuminemia, elevated alkaline phosphatase, and use of medications like warfarin, calcium, vitamin D, iron, and PTH analogs.
• Calciphylaxis currently has no approved treatments or standardized care protocols. Management relies on IV sodium thiosulfate, wound care, and metabolic correction, but efficacy is uncertain. Avoiding pro-calcific drugs and using adjuncts like intensified dialysis offer limited benefit. Prognosis remains poor, underscoring the need for targeted disease modifying therapies.
• The calciphylaxis drug pipeline is limited, with INZ-701 from Inozyme Pharma emerging as a leading investigational therapy, having completed its Phase I clinical trial.
• In July 2025, BioMarin completed its acquisition of Inozyme Pharma for USD 4.00 per share in an all-cash deal valued at approximately USD 270 million. The acquisition expanded BioMarin’s enzyme therapy portfolio with INZ-701, developing for 3 rare and progressive genetic disease affecting blood vessels, soft tissue, and bone.

Calciphylaxis Overview

Calciphylaxis is a rare, life-threatening disease characterized by widespread calcification of small blood vessels, leading to reduced blood flow, tissue ischemia, and subsequent skin and soft tissue necrosis. It most commonly occurs in individuals with advanced kidney disease, especially those on dialysis, although cases have been reported in people without kidney failure. 

Patients typically present with extremely painful, purplish-red or net-like skin lesions, most often on areas containing more fat such as the thighs, abdomen, and buttocks. As the disease progresses, these lesions can ulcerate, develop black-brown necrotic crusts, and often become infected, significantly increasing the risk of sepsis and mortality. The condition’s prognosis is poor, with high rates of morbidity and mortality, primarily due to non-healing wounds and subsequent infections.

Calciphylaxis Diagnosis and Treatment Algorithm 

Diagnosing calciphylaxis requires strong clinical suspicion, with confirmation typically made via skin biopsy revealing medial calcification of dermal arterioles, fibrointimal hyperplasia, microthrombi, or tissue necrosis. However, biopsies carry risks such as ulceration or infection, especially in early nodular lesions, prompting some clinicians to initiate treatment based on clinical judgment alone. A diagnostic workup includes metabolic panels, liver function, coagulation studies, and albumin levels, with hypercoagulable screening considered in select cases. Experimental methods like nuclear bone scans and fetuin-A level assessment may aid in diagnosis.

Management of calciphylaxis focuses on correcting bone-mineral imbalances, discontinuing high-risk medications, and providing wound care and symptom relief. Key steps include avoiding hypercalcemia, maintaining phosphorus levels below 5.5 mg/dL, and optimizing dialysis. Calcium-based phosphate binders should be replaced with non-calcium alternatives, and high-calcium dialysate baths avoided. Cinacalcet is preferred for secondary hyperparathyroidism, with etelcalcetide as an alternative.

Warfarin should be discontinued due to its association with calciphylaxis, and vitamin K supplementation is under investigation. Sodium thiosulfate, used off-label, has shown promising results in improving skin lesions, though its mechanism is not fully understood and may involve non–calcium-binding pathways. Debridement is often necessary, and hyperbaric oxygen therapy may support healing. Some improvement has been observed after kidney transplantation, but post-transplant cases can still occur, partly due to immunosuppressive therapy.

“Due to the potential involvement of bone-mineral imbalances in calciphylaxis, it is important to prevent hypercalcemia and keep serum phosphorus levels below 5.5 mg/dL. At the very least, patients should meet established dialysis adequacy standards, and dialysis frequency may be increased when needed to enhance the removal of uremic toxins and better regulate bone-mineral parameters.”

“Despite its high mortality rate, calciphylaxis lacks both definitive diagnostic tests and approved treatments. However, researchers have identified certain risk factors linked to poorer outcomes, including cardiovascular disease, diabetes mellitus, and the use of warfarin. These factors may contribute to increased mortality due to their association with widespread vascular calcification. 

“Calciphylaxis can occur in individuals with chronic kidney disease (CKD) even when their serum calcium and phosphate levels are within normal ranges. Notably, variations in the vitamin D receptor gene have also been linked to the development of this condition. Additionally, cases have been documented where calciphylaxis presents alongside nephrogenic fibrosing dermopathy in patients undergoing maintenance dialysis.”
