Treatment for dry mouth using stem cells in Sjögren's Syndrome patients

Intraglandular Treatment With Adipose-derived Mesenchymal Stem Cells in Patients With Xerostomia Due to Sjögrens Disease

Phase1; Phase2 Interventional Rigshospitalet, Denmark · NCT06805448

This study is testing whether injections of stem cells can help people with Sjögren's Syndrome who have dry mouth feel better and produce more saliva.

What this trial studies

This clinical trial investigates the use of adipose-derived mesenchymal stem cells (MSCs) to treat xerostomia, or dry mouth, in patients suffering from Sjögren's Syndrome. The study aims to assess the safety and efficacy of intraglandular injections of MSCs compared to a saline control. Participants will be monitored for improvements in saliva production and overall quality of life. The trial is designed to provide a new, potentially long-lasting treatment option for a condition that currently has limited therapeutic options.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older diagnosed with Sjögren's Syndrome and experiencing persistent dry mouth.

Not a fit: Patients who have other diseases affecting the salivary glands or are currently taking medications that cause dry mouth may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for patients with Sjögren's Syndrome by alleviating dry mouth symptoms.

How similar studies have performed: Previous studies have shown promising results using mesenchymal stem cells for similar conditions, indicating potential for success in this approach.
