SAN DIEGO & EDINBURGH, Scotland–(BUSINESS WIRE)–$DXCM #CGM—DexCom, Inc. (Nasdaq: DXCM), the global leader in real-time continuous glucose monitoring for people with diabetes, announced today the Dexcom G7 Continuous Glucose Monitoring (CGM) System is now available for people with diabetes age two years and older in the UK, Ireland, Germany, Austria and Hong Kong – marking the first major milestone in the availability of the revolutionary new technology. The company is also working quickly to introduce G7 in New Zealand and South Africa in the weeks ahead, with additional markets planned soon after.

“Since Dexcom G6 came to market, we’ve eliminated over 15 billion fingerpricks^‡ and helped improve the lives of more than 1.25 million people with diabetes around the world. We’re thrilled to begin the global rollout of Dexcom G7, our next-generation CGM technology, that vastly improves upon what everyone loves about G6,” said Kevin Sayer, chairman, president and CEO of Dexcom. “Dexcom CGM has become the gold standard of care for diabetes, and bringing our technology to more and more people around the world continues to be a top priority. With this initial launch behind us, we look forward to introducing G7 in additional markets and bringing this life-changing technology to as many people as we can.”

To introduce the highly anticipated new device, earlier today Dexcom hosted a global streaming launch event that delivered a behind-the-scenes look at the making of G7 and featured first-hand accounts from Dexcom Warriors from around the world discussing how Dexcom CGM has changed their lives.

“There were so many times, especially when Ava was first diagnosed, that our lives had to fit around the disease, and not the other way around,” said Rebecca Ridgeway, mother to six-year-old Ava, a budding gymnast managing Type 1 diabetes in the UK who was featured during the streaming event. “When we got Dexcom CGM, we felt like we’d finally been given a tool that gave us more control. It was lifechanging for us when Ava started using Dexcom, and Dexcom G7 brings it to a whole new level.”

The event also included comments from Dexcom leadership and key members of the G7 project team – Kevin Sayer, CEO; Jake Leach, COO; Anne Santoro, VP, global customer experience; Apurv Kamath, senior VP, product, global marketing; and Alex Diener, senior director, global product design.

“Dexcom customers from around the world were a part of the G7 design process,” said Diener, who helped design G7 and lives with Type 1 diabetes. “We learned from people living with Type 1 and Type 2 diabetes, younger and older patients, and their caregivers, about the CGM features they need to allow them to focus more on their everyday lives and less on managing diabetes.”

The streaming launch event can be viewed on demand at DexcomEvent.com.
