An observational study in Calciphylaxis, Calcific Uremic Arteriolopathy and End Stage Renal Disease, sponsored by Massachusetts General Hospital. Recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-14.
Sponsored by Massachusetts General Hospital · Observational
Calciphylaxis, a vascular calcification disorder, is a rare and serious disorder characterized by calcification of dermal arterioles.
There are significant gaps in the understanding of the pathophysiology and risk factors for calciphylaxis. At present, there is no effective treatment. Uncertain pathobiology, rare incidence and lack of collaborative approach have been some of the major limiting factors towards treating calciphylaxis.
The Partners Calciphylaxis Biorepository (PCB) aims to address these gaps within calciphylaxis research by utilizing existing and, when necessary, developing new infrastructure to support the consent of patients and the collection of dedicated samples for a calciphylaxis repository.

This repository is working in collaboration with the Partners Biobank as they will still be receiving samples from the PCB and storing them and distributing them according to their own procedures.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

No intervention
Number of patients with improvement in calciphylaxis skin lesions
Skin lesions will be assessed by investigators at baseline (entry into study) and at 6 months to determine whether there is improvement. The investigators will determine clinical, laboratory and genetic predictors of this outcome in calciphylaxis patients.
Time frame: 6 months
Number of patients with >30% improvement in pain severity
Pain severity will be assessed by investigators at baseline (entry into study) and at 4 weeks to determine whether there is improvement. Pain is measured using Wong-Baker Faces pain rating scale. The investigators will examine clinical, laboratory and genetic predictors of this outcome in calciphylaxis patients.
Time frame: 4weeks
Time to death in patients with calciphylaxis
Time to death is defined as time from the diagnosis of calciphylaxis to death (or to the end of follow up). The investigators will examine clinical, laboratory and genetic predictors of this outcome in calciphylaxis patients.
Time frame: Up to 5 years
Plan to share: No
The record gives a start of Jan 2017, a primary completion of Dec 2030 and a completion of Dec 2030. It does not say whether these dates are actual or estimated.
