About this study
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.
Read the detailed description
Calcific uremic arteriolopathy (CUA, calciphylaxis) is a rare disease (ORPHA280062) with dramatically high mortality characterized clinically by the occurrence of painful debilitating cutaneous lesions and ulcerations. Median survival time is about 1.5 years. Many uncertainties still exist about risk factors and optimal therapy. CUA mainly occurs in patients with severe renal insufficiency or ESRD.
The aim of the present initiative is to establish an international (European) observational registry for CUA patients. This registry will help to reach a critical mass of CUA patients, will allow novel insights into pathophysiology, and will help establishing systematically an overview upon risk factors and long-term outcome of CUA patients. The design of the international registry is supposed to adopt the structure of the presently running nation-wide German calciphylaxis registry.
The investigators plan to initiate a registry in which treating physicians can provide data upon demographics, clinical picture, comorbidities, medical treatments and laboratory data at the time of diagnosis and serial follow-up time points. In addition investigators will build-up a biobank for full blood, serum and plasma samples as well as tissue samples.
The registry will allow investigations regarding potential subgroups of patients (proximal versus distal forms of CUA), geno-phenotype correlations, description of international state-of-the-art treatment, and identification of preventive tools, risk factors and biomarkers for estimation of prognosis.
Furthermore, the registry will be the nidus for further scientific exchange between experts and clinicians on the field of uremic vascular calcification.

What is being measured
The primary outcome is the main question the study is designed to answer.
Prognosis of patients with calciphylaxis (survival time)
Survival time is defined as 1) time between diagnosis of calciphylaxis and death (or end of follow-up) or 2) - in case time of diagnosis is not recorded - time between registry recording and death (or end of follow-up). Analysis of survival time is done using the Kaplan-Meier survival analysis and Kaplan-Meier plot. With a Cox hazard model, we will try to identify additional factors influencing survival time. Hereby it is possible to take into consideration interaction between the parameters.
Measured: 5 years
Secondary outcomes (4)
Diagnosis of calciphylaxis
An internet based multilingual registry in which treating physicians can provide patients' data (online questionnaire) upon: demographics, the clinical picture including photo documentation and pain scale (VAS) reporting, comorbidities, medical treatments including dialysis and operations, wound management and laboratory data (serum-creatinine, , BUN, ionized / total calcium, serum phosphorus, PTH, alkaline, phosphatase, calcidiol, albumin, CRP, HbA1c, cholesterol, ferritin, hemoglobin, leukocyte count). The international registry will allow a more rapid identification of patients with calciphylaxis than on a national basis alone, will help establish diagnostic algorithms, and will increase the awareness of the disease.
Measured: 5 years
Risk factors
More detailed identification of risk factors: the registry will allow investigations regarding potential subgroups of patients (proximal versus distal forms of CUA), geno-phenotype correlations, description of international state-of-the-art treatment, and identification of preventive tools, risk factors and biomarkers for estimation of prognosis.
Measured: 5 years
Factors influencing prognosis of patients with calciphylaxis
Evaluation of the collected data from the time point of diagnosis and serial follow-up time points and further scientific exchange between experts and clinicians on the field of uremic vascular calcification will allow identification of subgroups of patients with potentially distinct pattern of risk factors, clinical picture and prognosis, and establishing factors influencing prognosis of patients with calciphylaxis and to develop novel and/or individualized treatment strategies
Measured: 5 years
Novel therapeutic options
By increasing the reported cases towards a critical threshold in Europe enabling the performance of RCTs comparing available or upcoming therapeutic options in CUA pts.
Measured: 5 years

Questions about this trial
What is this clinical trial studying?
An observational study of Calcific Uremic Arteriolopathy (CUA) and Calciphylaxis, run by RWTH Aachen University at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 14 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Vincent Brandenburg, MD, Prof. (+49 (0)241/80 ext. 36072, calciphylaxis@ukaachen.de), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Prognosis of patients with calciphylaxis (survival time) (time frame: 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02635373, which also lists 14 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Oct 2016; AzTrials last refreshed its copy on 28 Oct 2026.
