About this study
Official title: Effects of Human Amniotic-derived Mesenchymal Stem Cells (hAMSCs) on Calciphylaxis Patients: An Open-Label Single-Arm Study
Treatment for Calciphylaxis Patients with Human Amniotic-derived Mesenchymal Stem Cells
Read the detailed description
Calciphylaxis is a rare, devastating disorder causing excruciatingly painful ischemic skin lesions. Sepsis due to the infection of ulcerated wounds is a common cause of death. To date, practical therapies typically include wound care, pain management, anti-infection, anticoagulant and aggressive treatment of predisposing conditions. Drugs such as sodium thiosulfate(STS), bisphosphonate, SNF472 and cinacalcet are also suggested. However, it's still a lethal disease with 1-year mortality up to 80% for dialysis patients. Here the investigators plan to treat calciphylaxis patients with human amniotic-derived mesenchymal stem cells (hAMSCs).

What is being measured
The primary outcome is the main question the study is designed to answer.
Wound Healing
The Bates-Jensen Wound Assessment (BWAT) is a standardized tool for quantitative assessment of wound healing that includes the 13 items listed below: (1)Size; (2)Depth; (3)Edges; (4)Undermining or pockets; (5)Necrotic tissue type; (6)Necrotic tissue amount; (7)Exudate type; (8)Exudate amount; (9)Surrounding skin color; (10)Peripheral tissue edema; (11)Peripheral tissue induration; (12)Granulation tissue; (13)Epithelialization.
Each item was rated on a scale of 1 (best) to 5 (worst). The BWAT total score is the sum of the individual items with a possible range of 13 (best) to 65 (worst).
Measured: Up to 1 year.
Secondary outcomes (4)
Wound Pain
Assessed by pain visual analog scale (VAS). VAS Score is a horizontal line, 100 mm in length, anchored by word descriptors at each end. The subject marked the point on the line that represented his/her perception of his/her current pain status. VAS Score was determined by measuring in millimeters from the left hand end of the line (no pain) to the point that the subject marked. VAS Score range 0 (best) to 100 (Worst).
Measured: Up to 1 year.
Measured Quality of Life
The wound-quality of life(QoL) questionnaire measures the disease-specific, health related QoL of patients with chronic wounds. It consists of 17 items on impairments that are assessed in retrospect to the preceding 7 days and rated on a 0 (best) to 4 (worse) scale with possible responses from "not at all" to "very much". The total score is the average of the 17 responses.
Measured: Up to 1 year.
Systemic Infection
Assessed by serum hypersensitive C-reactive protein level(hCRP, mg/L). Increased serum hCRP levels above normal ranges indicate infection.
Measured: Up to 1 year.
Survival State
Survival time from the hAMSCs treatment started(momths)
Measured: From date of treatment until the date of die, assessed up to 1 year.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Human amniotic-derived mesenchymal stem cells in people with Chronic Kidney Diseases and Calciphylaxis, run by The First Affiliated Hospital with Nanjing Medical University at 1 site in China.
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 3 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 4 Mar 2026. 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 China. 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.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ningning Wang, Professor (86-013813821064 ext. +8613813821064, wangnn@njmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Wound Healing (time frame: Up to 1 year.). 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 NCT04592640, which also lists 12 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 4 Mar 2026; AzTrials last refreshed its copy on 27 Oct 2026.
