Dose-Escalation Trial of Mesenchymal Stromal Cells in Patients With Medical Xerostomia

Recruiting now · Phase 1

Conditions studied: Xerostomia, Graft-versus-host-disease, Sjogren's Disease

In brief

The goal of this clinical trial is to evaluate the safety and tolerability of injecting certain cells produced in bone marrow called mesenchymal stromal cells (MSCs) into salivary glands. The main question it aims to answer is whether injection of MSCs into salivary glands results in any improvement in dry mouth. Participants will: * have bone marrow collected using a needle * undergo a salivary gland ultrasound * complete questionnaires * receive an injection of the bone marrow cells into a salivary gland

• Use of investigational drugs, biologics, or devices within 30 calendar days prior to enrollment
• Pregnant or lactating women or those who plan to become pregnant during the study
• Not suitable for study participation due to other reasons at discretion of investigators.
• Enrollment in another clinical study possibly interfering with the endpoints of this study
