Fully miniaturized and automated, wearable closed-loop APDS for highly accurate and precise blood-glucose monitoring and control for the diabetes patients who need it most and beyond. Seraccess® NEXTRA operates with a proprietary transdermal port (SeraPort), the sophisticated architecture of which makes the sampling of minuscule amounts of blood possible in the first place. Only 20µl to 30µl of blood are needed to perform a highly accurate and precise blood glucose measurement. Seraccess® NEXTRA will be the first and only fully miniaturized and automated, wearable technology for the treatment of diabetes which communicates and interacts directly with the blood – and therefore the only solution which can meet the requirements for a true artificial pancreas. Not only for patients suffering from severe glycemic dysregulation, but also beyond into the broader indication of moderate glycemic dysregulation.
Brittle diabetes describes a group of diabetes patients suffering from life-changing disruptions due to severe glycemic dysregulation, indicating a condition of instability of glycemic control requiring frequent hospitalizations and causing impaired quality of life and enormous economic cost. These patients are at risk for many unfortunate consequences: poor glycemic control with its complications, more emergency room and hospital admissions, strains on relationships, and greater healthcare utilization and diabetes distress. Current standard of care cannot significantly help these patients, they spend very little time within the target blood glucose range.1 Brittle diabetes is characterized by severe instability of blood glucose levels with frequent and unpredictable episodes of hypoglycemia often requiring hospitalization. Hypoglycemia unawareness is one of the hallmarks of brittle T1D. Hypoglycemia unawareness is especially dangerous because the hypoglycemic individual will not know to take corrective action to prevent further deterioration. If left untreated, hypoglycemia may become severe, resulting in confusion, disorientation, loss of consciousness, or, in extreme cases of prolonged hypoglycemia, permanent brain damage or death.2 Equally dangerous are pronounced and prolonged hyperglycemias, which can lead to diabetic ketoacidosis (DKA) and associated frequent hospitalizations. Secondary complications, including neuropathy, cardiovascular disease, and retinopathy can be especially common in brittle T1D and there is a significant excess mortality in these patients despite intensive insulin therapy.3 A twenty-year outcome study showed a shockingly 50% mortality rate in a group of women with a mean age of 42 years. In a normal non-brittle type 1 diabetes population, the expected death rate over such a period would be about 5%.4,5
Seraccess® NEXTRA is a wearable device which operates nearly in real time and in direct communication with the patient's bloodstream. The nearly delay-free, highly accurate and precise blood-glucose measurement allows to administer the exact amount of insulin needed - via a proprietary transdermal port - directly into the bloodstream to manage blood glucose within the target range. An increase in time in range translates directly into a reduction of short- as well as long-term complications. Seraccess® NEXTRA is a fast acting closed-loop control system which can revolutionize therapy, first for patients suffering from severe glycemic dysregulation, then also beyond into the broader indication of moderate glycemic dysregulation.
The SeraPort catheter is inserted through the transdermal port, guided underneath the skin to the collarbone area and placed in the caval vein (vena cava). The port device connector connects the control device with the transdermal port.
How much blood is needed per day to measure blood glucose every 15 minutes?
The Seraccess® technology only needs 20µl to 30µl of blood to perform a measurement. At a frequency of 15 minutes, this results in 96 measurements per day which amounts to just 2ml to 3ml of blood needed per day. The sophisticated architecture of the transdermal SeraPort makes the sampling of such minuscule amounts of blood possible in the first place.
Brittle diabetes affects at least 3 in 1'000 insulin-dependent patients which translates to at least 26'000 patients in the US alone.6,7,8 The Brittle Diabetes Foundation uses glycemic variability (of 36% or more) to distinguish between brittle and stable type 1 diabetes and estimates 70'000 affected patients in the US alone.9 These patients suffer from recurrent DKA episodes resulting in multiple hospital admissions every year, with average costs of 30'000 USD per DKA admission.10 There were 189'000 hospital admissions for DKA in 2014, generating costs of 5.1 bn. USD.6 It is estimated that hospital admissions for DKA in 2021 have grown to more than 200'000, generating costs of about 6 bn. USD. On average, brittle diabetes patients account for 8 hospital admissions for DKA per year4, generating costs of around 240'000 USD per patient, despite the use of current state-of-the-art diabetes technology. Applying an annual flat fee per patient approach, market value is estimated to be at least 2 bn. USD. Beyond this, Diabetes represents a huge growing market with great innovation potential for technological improvements. Seraccess® NEXTRA can overcome the significant limitations of current solutions and better meet medical needs.
