Notes to Editors

About Arecor

Arecor Therapeutics plc is a clinical stage biotech company developing superior therapeutics that can reduce treatment burden and improve outcomes for people living with diabetes, obesity and other cardiometabolic diseases.

Arecor's research and development activity is focused on its two proprietary insulin candidates, AT278, an ultra-concentrated, ultra-rapid-acting insulin (500U/mL), and AT290, a concentrated, ultra-rapid-acting insulin (200U/mL). These insulins have been designed to enable the next generation of longer wear, miniaturised and fully closed loop automated insulin delivery (AID) systems, and have the potential to be the only insulins in development with the profile to achieve this.  These next generation AID systems in combination with Arecor's insulins have the potential to reduce treatment burden and improve outcomes for people living with both type 1 and type 2 diabetes who require intensive insulin therapy (IIT).

Broadening access to next generation AID systems also represents a significant commercial opportunity.  In the United States, there are approximately four million people with diabetes on IIT, who are candidates for AID.  This translates to an insulin revenue market of approximately $5 billion, of which Arecor has identified the people with the highest unmet need for its insulins represent approximately $3 billion market opportunity in the US alone.

Arecor is also developing a novel oral delivery platform for peptides with its first validation target a GLP-1 receptor agonist. Current treatment options are mostly limited to injectable therapies, due to the low oral bioavailability of orally delivered peptides and it is this challenge that Arecor is seeking to overcome.

The Company is quoted on AIM (AIM: AREC) and is based in Cambridge, UK. For further details please see www.arecor.com
