Clinical Trial Summary

The main objective of this study is to evaluate the tolerance and safety of autologous adipose-derived stromal vascular fraction injected in accessory salivary glands for treatment of autoimmune xerostomia in terms of adverse reactions through day 14 (D14).


Clinical Trial Description

Autoimmune xerostomia is a disabling condition affecting mostly patients suffering from Sjögren's disease, systemic lupus erythematosus, rheumatoid arthritis and systemic xerostomia. Local therapies and systemic drug treatments (picarpine) remain the gold standards but have limited effects upon salivary flow action and many adverse effects. Stem cell therapies and notably adipose tissue-derived stromal cells have shown promising potential for tissue repair. Autologous uncultured adipose-derived stromal vascular fraction (AD-SVF) is recognized as an easily accessible (by a standard lipoaspiration to obtain adipose tissue, from which AD-SVF are isolated by centrifugation), safe and well tolerated source of cells with angiogenic, anti-inflammatory, immunomodulatory and regenerative properties. The purpose of our AD-SVF phase I trial is to evaluate, first the tolerance of autologous AD-SVF cells locally injected in the oral cavity and second their capability to improve the salivary function. ;
