Human amniotic-derived mesenchymal stem cell treatment for calciphylaxis

Effects of Human Amniotic-derived Mesenchymal Stem Cells (hAMSCs) on Calciphylaxis Patients: An Open-Label Single-Arm Study

Early Phase 1 Interventional The First Affiliated Hospital with Nanjing Medical University · NCT04592640

This will try human amniotic-derived mesenchymal stem cells as a treatment for adults 18–75 who have calciphylaxis, including people with chronic kidney disease whether they are on dialysis or not.

What this trial studies

This is an early phase 1 interventional trial delivering human amniotic-derived mesenchymal stem cells (hAMSCs) to adults with clinically diagnosed calciphylaxis. The primary focus is safety, with participants monitored for adverse events, wound healing, pain, and infection outcomes. Eligible participants are 18–75 years old and must provide informed consent, while people who are pregnant, have active malignancy, severe psychiatric disorder, or very limited life expectancy are excluded. The trial is conducted at hospitals in Nanjing, China, with scheduled treatment and follow-up visits to evaluate short-term tolerability and preliminary signals of benefit.

Who should consider this trial

Good fit: Adults aged 18–75 with a clinical diagnosis of calciphylaxis, including those with chronic kidney disease on dialysis or not, who can give informed consent are ideal candidates.

Not a fit: Patients with active cancer, severe psychiatric disorders, expected survival under six months, pregnant or breastfeeding women, or those recently enrolled in another experimental drug trial may not be eligible or likely to benefit.

Why it matters

Potential benefit: If successful, the treatment could reduce pain, promote healing of ischemic skin lesions, lower infection and sepsis risk, and improve survival for patients with calciphylaxis.

How similar studies have performed: Use of amniotic-derived MSCs for calciphylaxis is largely novel, though small studies of mesenchymal stem cells for difficult-to-heal wounds and related conditions have shown promising but preliminary results.
