Using stem cells to treat difficult cases of Type 2 diabetes

Safety and Efficacy of OCN19-overexpressed Human Umbilical Cord-derived Mesenchymal Stem Cells in the Treatment of Refractory Type 2 Diabetes Mellitus

This study is testing whether injecting special stem cells can help people with hard-to-treat Type 2 diabetes better manage their blood sugar along with their usual medications.

What this trial studies

This clinical trial investigates the safety and efficacy of injecting human umbilical cord-derived mesenchymal stem cells that overexpress OCN19 in patients with refractory Type 2 diabetes mellitus. The approach aims to enhance insulin gene expression and promote the proliferation of islet beta cells, potentially improving glycemic control. Participants will receive these specialized stem cells along with standard treatments to assess their effectiveness compared to traditional therapies. The study is designed for individuals who have struggled to manage their diabetes with existing medications.

Who should consider this trial

Good fit: Ideal candidates are adults aged 30-75 with Type 2 diabetes who have been on insulin therapy for at least six months and have specific blood glucose and BMI criteria.

Not a fit: Patients with Type 1 diabetes or other specific types of diabetes, as well as those with severe allergies, may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve blood sugar control in patients with difficult-to-manage Type 2 diabetes.

How similar studies have performed: While the use of stem cells in diabetes treatment is an emerging field, this specific approach with OCN19-overexpressed cells is novel and has not been extensively tested in prior studies.
