\"DRI<\/a>The Diabetes Research Institute (DRI), a Center of Excellence at the University of Miami Miller School of Medicine, announced today that the first patient in its clinical trial\u00a0has been free from insulin injections in record time following the implantation of islet cells within a biological scaffold.\u00a0The patient, Wendy Peacock, 43, from San Antonio, TX, underwent the minimally invasive procedure on August 18, 2015, and is now producing her own insulin naturally for the first time since being diagnosed with type 1 diabetes at age 17. In this pilot study, DRI researchers are testing a new transplant technique for insulin-producing cells, building upon decades of progress in clinical\u00a0islet transplantation. This trial is an important first step toward the development of the DRI BioHub<\/a>, a bioengineered mini-organ that mimics the native pancreas to restore natural insulin production in people with type 1 diabetes.<\/p>\n

\u201cThe first subject\u00a0in our Phase I\/II pilot BioHub trial is now completely off insulin with an excellent glucose profile. These are the best post-transplant results we’ve seen in an islet recipient,” said\u00a0Camillo Ricordi, MD<\/a>, director of the DRI and the Stacy Joy Goodman Professor of Surgery, Distinguished Professor of Medicine, Professor of Biomedical Engineering, Microbiology and Immunology at the University of Miami Miller School. Dr. Ricordi also serves as director of the DRI\u2019s Cell Transplant Center. \u201cThis\u00a0was the first tissue engineered islet transplant using a \u2018biodegradable scaffold\u2019 implanted on the surface of the omentum. The technique has been designed\u00a0to minimize the inflammatory reaction that is normally observed when islets are implanted in the liver or in other sites with immediate contact to the blood.\u00a0If these results can be confirmed, this can be the beginning of a new era in islet transplantation. Our ultimate goal is to include additional technologies to prevent the need for life-long anti-rejection therapy,” Dr. Ricordi added.<\/p>\n

The omentum is a highly vascularized tissue covering abdominal organs. The donor islets were implanted within a biodegradable scaffold, one of the platforms for a DRI BioHub, made by combining\u00a0the patient’s own blood plasma\u00a0with thrombin, a commonly used, clinical-grade enzyme. Together, these substances create a\u00a0gel-like material that sticks to the omentum and holds the islets in place. The omentum is then folded over around the biodegradable scaffold mixture. Over time, the body will absorb the gel, leaving the islets intact, while new blood vessels are formed to provide critical oxygen and other nutrients that support the cells\u2019 survival.\u00a0 This pilot trial will include the immunosuppressive regimen currently used for clinical islet transplantation studies and will be limited to a small group of participants.SEE INFOGRAPHIC<\/strong> BELOW<\/p>\n

\n“As any type 1 knows, you live on a very structured schedule. I do a mental checklist every day in my head…glucose tabs, food, glucometer, etc., and then I stop and say, ‘WOW! I don’t have to plan that anymore.’ Laying down at night and going to sleep and not having to worry about lows is something that is so foreign to me. It’s surreal to me…I’m still processing the fact that I’m not taking insulin anymore,” said Peacock, who was a candidate for the DRI’s clinical trial because she suffered with severe hypoglycemia unawareness, a complication of diabetes in which patients are unable to sense that their blood glucose is dropping to dangerously low levels. People with hypoglycemia unawareness often become disoriented, lose consciousness or go into convulsions. It may even lead to death.<\/p>\n

\u201cWe’re quite excited. This has been the best outcome we have seen at this stage. It’s a unique site, the surgery is very simple and the patient recovers very quickly. We will continue until our final goal – islet transplantation without immunosuppression,”\u00a0adds Rodolfo Alejandro, MD<\/a>, Professor of Medicine and director of the DRI Clinical Cell Transplant Program.<\/p>\n

In type 1 diabetes, the insulin-producing islets cells of the pancreas have been mistakenly destroyed by the immune system, requiring patients to manage their blood sugar levels through a daily regimen of insulin therapy. Islet transplantation has allowed some patients to live without the need for insulin injections after receiving a transplant of donor cells. Some patients who have received islet transplants at the DRI have been insulin independent for more than a decade, as DRI researchers have published.<\/p>\n

Currently, islet cells are infused into the liver, but many of the cells do not survive in that environment. \u201cThe liver is a very simple site to access, but we have known for years that it\u2019s not the ideal site. And the liver will not accommodate a device for housing the islets,\u201d explained Dr. Alejandro.<\/p>\n
