Active clinical trials for "Calciphylaxis"

Calcific uremic arteriolopathy a.k.a. calciphylaxis is a vascular calcification disorder seen in dialysis patients. Calcific uremic arteriolopathy has 60-80% one-year mortality and significant morbidity associated with non-healing and extremely painful skin lesions. At present, there is no effective treatment for calcific uremic arteriolopathy. Vitamin K is an important vitamin for inhibiting vascular calcification. It is known to increase the circulating levels of carboxylated Matrix Gla Protein, a potent inhibitor of vascular calcification. However, the effects of vitamin K supplementation in patients with calcific uremic arteriolopathy are unknown. The purpose of this study is to conduct a pilot randomized controlled trial to examine the effects of oral vitamin K supplementation on circulating levels of anti-calcification factor (carboxylated Matrix Gla Protein) and clinical outcomes in patients with calcific uremic arteriolopathy.

To evaluate the effect of SNF472 on top of standard of care on promoting wound healing and other parameters of therapeutic response in haemodialysis patients with calciphylaxis (calcific uraemic arteriolopathy, CUA).

This is an 8-week observational follow-up study of patients who participated in the ST-001 CALISTA study (A Phase 3, Intravenous Sodium Thiosulfate for Acute Calciphylaxis Treatment: A Multicenter, Randomized, Double-blind, Placebo-controlled Clinical Trial).

Calciphylaxis, also called Calcific Uremic Arteriolopathy (CUA) is a lethal affection mostly affecting patient in end stage renal disease. The survival rate is described around 20 to 46% at one year. Clinical presentation is very painful skin lesions with ulceration mostly located on the trunk or thigh. Current knowledge about physiopathology, diagnostic practice and therapeutic is very limited. Actually there is no European study about calciphylaxis and risk factors, diagnostic practice and outcome factors.

Martorell hypertensive ischemic leg ulcer is a severe type of skin necrosis (skin infarction) which occurs in long-term hypertensive subjects. Calciphylaxis (calcific uremic arteriolopathy) is a severe type of skin necrosis (skin infarction) which occurs in subjects with end-stage kidney disease or after kidney transplantation.

The national drug safety agency authorizes nominatively the use of sodium thiosulfate in dialysis patients with calciphylaxis. To date, it is the largest global cohort (more 600 patients from 2012 to 2016). We wanted to study retrospectively the fate of these patients at 6 months including mortality. Early use improves effectiveness.

Observational, registry, prospective, non-interventional collection of CUA patient data. Patient treatment is carried out within clinical routine, at the discretion of the physicians and according to existing treatment guidelines. Participating physicians will not be subject to any instructions with regard to the diagnosis and therapy of their patients.
