Insulin producing islet cells


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. 

If you are interested in participating in this clinical trial, please contact the DRI Clinical Program at 305-243-5321 or 305-243-6070.

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.

You may find the full list of inclusion/exclusion criteria on the ClinicalTrials.gov website. You can also contact the Diabetes Research Institute at: 305-243-5321 or 305-243-6070.

2. How many patients will participate in this research study?
A total of 56 patients will participate, 28 adults and 28 children.

3. If I participate in this study, what will I have to do?

No, omega-3 and vitamin D will be provided at no cost.

6. Will I be compensated for my participation or reimbursed for travel expenses if I get involved in this study?
