Abstract

The disclosure provides methods for treating diabetes by promoting graft survival and improved graft function in a patient receiving an islet transplant by treating the patient with a GLP-1 receptor agonist compound prior to the islet transplant. The methods may also comprise treating the islets with a GLP-1 receptor agonist compound prior to transplanting them in a patient. The methods may eliminate the need for immunosuppressive therapy in islet transplants. Any GLP-1 receptor agonist compound know in the art can be used in the methods described herein.

Claims (8)

1. A method for treating diabetes in a patient in need thereof, the method comprising:

(i) administering a therapeutically effective amount of a GLP-1 receptor agonist compound to the patient for a period of time of 1 day to 1 month prior to allogeneic islet transplant; and

(ii) transplanting allogeneic islets into the patient;

thereby treating the diabetes in the patient, wherein the patient is not administered an immunosuppressive drug or an immunosuppressive treatment regimen before, during, or after any step in the method.

2. The method of claim 1 , wherein the patient is a human.

3. The method of claim 1 , wherein the GLP-1 receptor agonist compound is an exendin, a GLP-1(7-37), or an analog thereof.

4. The method of claim 1 , wherein the GLP-1 receptor agonist compound comprises the amino acid sequence as set forth in SEQ ID NO:1, 3, or 23.

5. The method of claim 1 , wherein the GLP-1 receptor agonist compound is exenatide, lixisenatide, liraglutide, dulaglutide, albiglutide, or taspoglutide.
