Huge step forward for HealthKit, iOS, iPhone, AppleWatch: FDA permits marketing of first system of mobile medical apps for continuous glucose monitoring

January 23, 2015 – The U.S. Food and Drug Administration today allowed marketing of the first set of mobile medical apps that allow people with diabetes to automatically and securely share data from a continuous glucose monitor (CGM) with other people in real-time using an Apple mobile device such as an iPhone. thasso makes here this release available to its followers since thasso sincerely beliefs that this regulatory step by the FDA paves the way for many more similar devices to come, all geared towards collecting vital data from patients, having them transmitted to caregivers and doctors, and, may be, have intelligent knowledge systems push useful health and/or medical informations back to the patient. See below the press release by the FDA.
Press Release – The U.S. Food and Drug Administration today allowed marketing of the first set of mobile medical apps that allow people with diabetes to automatically and securely share data from a continuous glucose monitor (CGM) with other people in real-time using an Apple mobile device such as an iPhone.
The Dexcom Share Direct Secondary Displays system’s data-sharing capability allows caregivers to a person with diabetes to monitor that individual’s blood sugar levels remotely through a legally marketed device that is available on mobile devices. Devices like the Dexcom Share were previously available through open source efforts, but were not in compliance with regulatory requirements. The Dexcom Share system is the first of its kind to offer a legally marketed solution for real-time remote monitoring of a patient’s CGM data. “This innovative technology has been eagerly awaited by the diabetes community, especially caregivers of children with diabetes who want to monitor their glucose levels remotely,” said Alberto Gutierrez, Ph.D., director of the Office of In Vitro Diagnostics and Radiological Health in the FDA’s Center for Devices and Radiological Health. “Today’s marketing permission paves the way for similar technologies to be marketed in the United States.”
A CGM is a device that includes a small, wire-like sensor inserted just under the skin that provides a steady stream of information about glucose levels in the fluid around the cells (interstitial fluid). CGMs are worn externally and continuously display an estimate of blood glucose levels, and the direction and rate of change of these estimates. When used along with a blood glucose meter, CGM information can help people with diabetes detect when blood glucose values are approaching dangerously high and dangerously low levels.
The Dexcom Share system displays data from the G4 Platinum CGM System using two apps: one installed on the patient’s mobile device and one installed on the mobile device of another person. Using Dexcom Share’s mobile medical app, the user can designate people (“followers”) with whom to share their CGM data. The app receives real-time CGM data directly from the G4 Platinum System CGM receiver and transmits it to a Web-based storage location. The app of the “follower” can then download the CGM data and display it in real-time.
The FDA reviewed data for the Dexcom Share system through the de novo classification process, a regulatory pathway for low- to moderate-risk medical devices that are novel and not substantially equivalent to any legally marketed device. Data provided by the device maker showed the device functions as intended and transmits data accurately and securely.
Because the device is low to moderate risk, the FDA has classified the device as class II exempt from premarket submissions. In the future, manufacturers wishing to market devices like the Dexcom Share system will not need premarket clearance by the FDA prior to marketing, but they will still need to register and list their device with the agency, as well as follow other applicable laws and regulations.
“Exempting devices from premarket review is part of the FDA’s effort to ensure these products provide accurate and reliable results while still encouraging the development of devices that meet the needs of people living with diabetes and their caregivers,” said Gutierrez.
The Dexcom Share system does not replace real-time continuous glucose monitoring or standard home blood glucose monitoring. It is also not intended to be used by the patient in place of a primary display device. Additionally, CGM values alone are not approved to determine dosing of diabetes medications. CGMs must be calibrated by blood glucose meters, and treatment decisions, such as insulin dosing, should be based on readings from a blood glucose meter.
Diabetes is a serious, chronic metabolic condition where the body is unable to convert glucose into the energy needed to carry out daily activities. An estimated 25.8 million people in the U.S. – about 215,000 of them under age 20 – have diabetes. If left untreated, high blood glucose levels (hyperglycemia) can lead to serious long-term problems such as stroke, heart disease, and damage to the eyes, kidneys and nerves.
The Dexcom Share system is manufactured by Dexcom, Inc., located in San Diego, California.
