What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the safety and effectiveness of the Cell Pouch, an implantable device for people with Type 1 Diabetes who struggle with severe low blood sugar. The device holds insulin-producing cells in a natural, blood-rich environment to help them survive and function well. The study will monitor patients over several years to ensure the treatment is safe and works as intended.

Will I have to stop taking my current medications?

The trial requires that you stop taking any anti-diabetic medication other than insulin within 4 weeks of the transplant. If you are on systemic steroids, you may need to adjust your dosage unless it's 5 mg or less of prednisone daily or an equivalent dose of hydrocortisone for replacement purposes.

How is the Sernova Cell Pouch treatment different from other treatments for type 1 diabetes?

The Sernova Cell Pouch treatment is unique because it involves implanting a small device under the skin that houses insulin-producing cells, potentially reducing the need for frequent insulin injections and continuous glucose monitoring, unlike traditional insulin therapies. ^{1 2 3 4 5}

Are You a Good Fit for This Trial?

Adults aged 18-65 with Type 1 Diabetes Mellitus, hypoglycemia unawareness, and severe hypoglycemic episodes can join. They must be under intensive diabetes management and have no stimulated c-peptide response. Exclusions include kidney issues, substance abuse, severe heart disease, uncontrolled lipid levels, certain infections or cancers, immunosuppressive treatments, high HbA1c levels or blood pressure, previous transplants (pancreas/islet), allergies to polymers and those not using contraception.

Inclusion Criteria

You are not aware when your blood sugar gets too low.

I am mentally stable and can follow the study's procedures.

I manage my diabetes intensively with multiple daily checks and insulin doses, under a specialist's care.

Exclusion Criteria

I have diabetic eye disease that hasn't been treated.

I am not pregnant, not breastfeeding, and willing to use contraception during and 4 months after the study.

Known allergy or hypersensitivity to polymers More information on this criterion is in the protocol

Timeline for a Trial Participant

Screening

5 years

What Are the Treatments Tested in This Trial?

Interventions

• Sernova Cell Pouch™

Trial Overview The trial is testing the Cell Pouch™ implanted with insulin-producing cells for treating Type 1 Diabetes in patients who don't sense low blood sugar well. The device aims to create a natural environment for cell transplant and function within the body by forming tissue chambers that support engraftment of these cells.

How Is the Trial Designed?

Group I: T1D Cell Pouch Recipients Experimental Treatment 1 Intervention

Eligible Type 1 Diabetes Mellitus (T1D) subjects with hypoglycemia unawareness and a history of severe hypoglycemic episodes undergoing Sernova Cell Pouch intervention

Published Research Related to This Trial

A study comparing severe hypoglycaemia in type 1 diabetes patients from 1984 to 1998 found a more than 50% increase in prevalence, despite better management practices like multiple insulin injections and daily blood glucose monitoring.

The research identified that factors like unawareness of hypoglycaemia and HbA1c levels contributed to this increased risk, suggesting that new insulin therapies and improved glucose monitoring systems are needed to better protect patients from severe hypoglycaemic episodes.

The Medtronic 670G device has been shown to significantly reduce the burden of managing Type 1 diabetes by improving insulin dosing safety and effectiveness.

Advancements in insulin products and glucose monitoring technologies, including the Medtronic 670G, have contributed to fewer long-term complications and instances of hypoglycemia for individuals with Type 1 diabetes.

The development of automated insulin dosing systems, like the Medtronic MiniMed 670G and 780G, represents significant advancements in managing type 1 diabetes by aiming to 'close the loop' between glucose monitoring and insulin delivery.

DIY artificial pancreas systems, such as OpenAPS, AndroidAPS, and Loop, have emerged from the #WeAreNotWaiting movement, allowing patients and caregivers to create personalized solutions for insulin management, demonstrating real-world benefits in self-management for users across different age groups.

The MiniMed™ 670G system with SmartGuard™ technology was safely used at home by 105 children with type 1 diabetes for 3 months, showing no severe hypoglycemia or diabetic ketoacidosis incidents.

Participants experienced significant improvements in glucose control, with a decrease in HbA1c from 7.9% to 7.5% and an increase in time spent within the target glucose range from 56.2% to 65.0%.
