OPKO Health Enrolls First Patient in Phase 2b Study of OPK88003 to Treat Type 2 Diabetes

MIAMI, FL, USA I March 23, 2018 I OPKO Health, Inc. (NASDAQ:OPK) has enrolled the first patient in a Phase 2b dose escalation trial of OPK88003, a once-weekly oxyntomodulin therapy containing dual agonist activity towards GLP-1 and Glucagon receptors, to treat type 2 diabetes and obesity.  Based on preclinical and Phase 2 data, the use of once-weekly dual agonists, such as OPK88003, could more effectively improve glucose control, increase weight loss and improve the lipid profile in type 2 diabetics compared to the current GLP—1 therapies on the market.

According to the American Diabetes Association (ADA), the prevalence of type 2 diabetes continues to grow in the U.S., affecting approximately 30 million people, with 1.5 million Americans diagnosed each year.   The ADA estimates the annual cost of diabetes in the U.S. to be in excess of $245 billion.1

The Phase 2b trial will enroll approximately 110 subjects with type 2 diabetes at up to 35 clinical sites in the U.S. to evaluate a dose escalation regimen of OPK88003 to reduce HbA1c levels over a 30 week treatment period, the primary efficacy endpoint of the study.  The study will also assess weight loss and lipid composition, the secondary endpoints.

OPK88003 was previously evaluated in a blinded Phase 2 clinical trial of 420 patients with type 2 diabetes for 12 weeks, followed by an open label extension for an additional 12 weeks.  The study showed that OPK88003 reduced HbA1c levels by approximately 1.4% and resulted in statistically superior weight loss compared to the comparator, a weekly exenatide. Further, OPK88003 treatment resulted in a favorable decrease in triglycerides and cholesterol in comparison to the weekly exenatide.

"Our confidence in this program is supported by the earlier Phase 2 data and we are enthusiastic to be initiating this study in type 2 diabetics to evaluate the effects of a refined dosing regimen of oxyntomodulin on glucose control and weight loss in preparation for a pivotal Phase 3 program. The dual agonist activity of OPK88003 may provide improved benefits in the treatment of diabetes, resulting in better glucose control and improved long-term cardiovascular outcomes, and we believe it has the potential to offer improved benefits compared with the current once-weekly GLP-1 therapies in a growing diabetes market," stated Phillip Frost, M.D., Chairman and Chief Executive Officer of OPKO Health.
