Curing Diabetes

Clinical Trial – POSEIDON Study

Type 1 diabetes is an autoimmune disease that occurs when the immune system attacks and destroys the insulin-producing cells in the pancreas. The Diabetes Research Institute at the University of Miami is currently offering a research protocol for patients with type 1 diabetes within 10 years of diagnosis, and between the ages of 6 – 65 years.

The purpose of this research study is to compare the safety and effectiveness of two oral medications (vitamin D and omega-3) that may slow-down or stop the progression of the autoimmune process and preserve your insulin-producing cells.

Frequently Asked Questions (FAQ)

1. How will I know if I am eligible to participate in this study?
You will need to be between the ages of 6 and 65 years and have been diagnosed with type 1 diabetes within the last 10 years.
You will also need to have evidence of some insulin production by your insulin producing cells. We can check for this by testing your levels of C-peptide in your blood. This will be done during a mixed meal tolerance test where you will drink a liquid meal containing a specific amount of protein, fat and carbohydrates and blood samples will be obtained through an IV placed in an arm vein. Your C-peptide during this test will need to be ≥0.2 ng/mL in order to be eligible.
