Grant Award Details
A phase 1 trial of Pancreatic Islets and Parathyroid Gland Co-transplantation for Treatment of Diabetes in the Intra-Muscular Site: PARADIGM
Grant Application Details
- Pancreatic Islets and Parathyroid Gland Co-transplantation for Treatment of Diabetes in the Intra-Muscular Site: PARADIGM
Therapeutic Candidate or Device
Human pancreatic islets and parathyroid gland combination graft
Patients with established Type 1 diabetes
Pancreatic islet transplantation has become a more viable approach to treat patients with established Type 1 diabetes. However, widespread application has been limited by several barriers, most importantly, poor islet survival and an inability to monitor islets after transplant. Co-transplantation of parathyroid tissue with pancreatic islets leads to dramatic improvement in islet survival and function after intramuscular transplant, which enables easy access and monitoring.
Unmet Medical Need
The ability to restore long-term normal blood glucose levels with islets from a single donor, using a low morbidity procedure, in a retrievable site that can be non-invasively monitored has not been attainable previously. The PARADIGM trial is aimed at addressing this critical unmet need.
Phase I/IIa trial completed
Major Proposed Activities
- Perform phase I/IIa safety and efficacy trial of pancreatic islet and parathyroid co-transplantation in the muscle of patients with Type 1 diabetes
- Perform safety analysis and efficacy assessment of islet and parathyroid grafts in a novel intramuscular islet transplant site
- Perform exploratory studies on islet engraftment mechanisms and immunologic monitoring of pancreatic islet and parathyroid grafts
Diabetes affects 2.3 million Californians with annual healthcare costs of over $12 billion. If successful, this work can lead to a more effective therapy that directly benefits patients with Type 1 diabetes and those who are on insulin therapy. By developing a retrievable transplant site, it also paves the way for future clinical translation of stem cell-derived islets that can potentially invigorate research and biotechnology development in California.
