Pregnancy Intervention With a Closed-Loop System (PICLS) Study

In pregnancies associated with diabetes, lowering glucose to the recommended targets to prevent adverse health outcomes often leads to significant hypoglycemia. Hybrid closed-loop (HCL) therapy, automated insulin delivery using an insulin pump getting feedback from a continuous glucose monitor (CGM), may improve outcomes. This exploratory, novel pilot feasibility randomized clinical trial will evaluate pregnant women with type 1 diabetes (T1D) on HCL therapy or Sensor-Augmented Pump Therapy (SAPT, non-communicating pump and CGM) from the 2nd trimester, throughout pregnancy, and 4-6 weeks post-partum. Comparisons will be made on safety (Specific Aim [SA] 1), indices of glycemic variability and fear of hypoglycemia (SA 2), and quality of life and device satisfaction (SA 3) between groups. Exploratory SA 4 will compare maternal and fetal outcomes between groups. Safety data will include episodes of severe hypoglycemia requiring 3rd party assistance, diabetic ketoacidosis, and skin reactions. Glycemic control will be measured by CGM time spent in glucose ranges (<63, 63-140, >140 mg/dL) and other measures of glycemic variability. Subjects will fill out surveys (Fear of Hypoglycemia, a quality of life survey, and 2 questionnaires about device satisfaction) at baseline, throughout gestation, and early post-partum. Data on maternal and fetal outcomes will be collected. Findings will reveal the safety profile and glucose control with a novel therapy for pregnant women with type 1 diabetes.

A Safety, Tolerability and Efficacy Study of Sernova's Cell Pouch™ for Clinical Islet Transplantation

The Cell Pouch™ is a novel implantable device, that is transplanted with therapeutic cells such as insulin producing islets. This combination product is designed for the treatment of Type 1 Diabetes Mellitus (T1DM) with hypoglycemia unawareness and a history of severe hypoglycemic episodes. Upon implantation, the Cell Pouch™ is designed to form a natural environment, rich in tissue and microvessels for the transplant and function of therapeutic cells. The Cell Pouch™ is designed as a scaffold made of non-degradable polymers, formed into small cylindrical chambers which, when placed in the subcutaneous site, becomes incorporated with tissue and microvessels to the circumference of removable plugs within as early as two weeks as demonstrated in preclinical studies. After the tissue incorporation, the plugs are removed, leaving fully formed tissue chambers with central void spaces for the transplantation of therapeutic cells including Islets of Langerhans (islets). The Cell Pouch™ forms a natural environment, rich in microvessels that allows the transplanted islets to engraft with intravascular microvessels. It is believed this engraftment will enable long-term survival and function of transplanted islets. This study aims to demonstrate the safety and tolerability of islet transplantation into the Cell Pouch™ for the treatment of T1DM in subjects with hypoglycemia unawareness and a history of severe hypoglycemic episodes. The study also aims to establish islet release criteria that accurately characterize the islet product and are predictive of clinical transplant outcomes into the Cell Pouch™, which will be demonstrated through defined efficacy measures.

FASter Insulin in Closed-loop Technology in Children

The main objective of this study is to compare 24/7 hybrid closed-loop insulin delivery under free living conditions applying faster insulin aspart (FiAsp) to 24/7 hybrid closed-loop insulin delivery applying standard insulin aspart in very young children with type 1 diabetes. The closed-loop system consists of three components: the continuous glucose monitor (CGM), the insulin pump and a smartphone Application, or App, that translates, in real-time, sensor glucose levels received from the glucose monitoring device and calculates the amount of insulin to be delivered by the coupled insulin pump. This is a double-blind, multi-centre, randomised, crossover design study, involving a run-in period followed by two 8-week study periods during which glucose levels will be controlled by a hybrid closed-loop system using either standard insulin aspart or faster insulin aspart in random order. Participants aged 2-6 years with type 1 diabetes on insulin pump therapy will be recruited through paediatric diabetes outpatient clinics at participating clinical centres. Enrolment will target up to 30 children (aiming for 6-14 participants per centre) to allow for dropouts during run-in. Prior to the use of study devices, participants and parents/guardians will receive appropriate training by the research team on the safe use of the study pump and CGM device, and the hybrid closed-loop insulin delivery system. Parents/guardians at nursey/school may also receive training by the study team if required. Participants will have regular contact with the study team during the study including 24/7 telephone support. Parents/guardians will be asked to complete validated questionnaires at the start and end of the study to assess quality of life measures including sleep. The primary outcome is the between group difference in time spent in target range between 3.9 and 10.0 mmol/l as recorded by CGM during the study. Secondary outcomes are time spent with glucose levels above and below target, as recorded by CGM, and other CGM-based metrics. Safety evaluation comprises assessment of the frequency and severity of hypoglycaemic episodes and diabetic ketoacidosis (DKA).

Hypoglycaemia Awareness Restoration Programme

Insulin treatment for type 1 diabetes inevitably carries risk of hypoglycaemia (low blood sugar) which can be severe enough to cause coma, seizure, even death. Being unable to feel when blood glucose is falling, a condition called impaired awareness of hypoglycaemia (IAH), increases risk of severe hypoglycaemia 6-fold. IAH can be reversed and risk of severe hypoglycaemia reduced when people are taught how to adjust their insulin around their life-styles through structured education but problematic hypoglycaemia may persist. Many people with apparently intractable IAH and recurrent severe hypoglycaemia have thoughts about hypoglycaemia that form barriers to their ability to avoid hypoglycaemia. They cannot benefit from conventional treatments to reduce hypoglycaemia. The investigators developed the Hypoglycaemia Awareness Restoration Programme for people with type 1 diabetes and problematic hypoglycaemia despite otherwise optimised self-care (HARPdoc), a novel intervention that combines revision of knowledge about hypoglycaemia avoidance with psychological therapies that directly address unhelpful health beliefs about hypoglycaemia. HARPdoc is delivered over six weeks, by diabetes educators to groups of 6 people. In a pilot study, severe hypoglycaemia was greatly reduced in 23 people with very longstanding IAH and recurrent severe hypoglycaemia. The investigators propose a group-randomised controlled trial of HARPdoc, comparing it to an established educational intervention (Blood Glucose Awareness Training, BGAT) which has also been shown to reduce severe hypoglycaemia. 96 people with type 1 diabetes and problematic hypoglycaemia persisting despite otherwise optimised insulin self-management will be recruited into groups which will be randomised to receive either HARPdoc or BGAT, in 4 centres. The investigators will measure severe hypoglycaemia over two years following courses; hypoglycaemia risk and experience; overall diabetes control and quality of life.

CoYoT1 to California

CoYoT1 to California (CTC) was initiated to develop a patient-centered, home telehealth care model for young adults (YA) ages 16-25 with T1D. It is a 2x2 factorial design, 15-month intervention. Eighty participants will be randomized to Standard Care or CoYoT1 Care, which is delivered by telehealth or in-person. CoYoT1 Care is a patient-centered care model that consists of three major components: shared decision making (patient and provider agree upon priorities for the medical visit), autonomy and supportive care (provider training in communication strategies such as motivational interviewing), and goal setting and action planning (provider training to coach YA in setting SMART goals, developing action plans, and designing follow up plans). Additionally, didactic expert-led sessions (Standard Care) or peer-led, YA-driven group sessions (CoYoT1 Care) are included. At the end of the study, a focus group will be completed to assist in determining which features YA felt were critical to their success from the telehealth intervention, group components, and provider behaviors. ***COVID-19 Update: Due to current hospital and clinical policy adaptation for COVID-19, all participants who were randomized into in-person appointments will now receive care via Telehealth. Telehealth has been implemented hospital-wide and will be the temporary delivery of care method during this pandemic. Participants have been notified of this change and given instruction on how to participate in a Telehealth appointment.
