Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Can healthy volunteers participate?
No
Key exclusion criteria
1. Participants whose average total daily insulin dose exceeds 85 units per day (i.e. typically change insulin reservoirs more often than every 3.5 days on average)
2. Participants who routinely change their commercial insulin infusion sets twice weekly or less often (wear time greater than 3.5 days)
3. Female participant is pregnant or nursing (Documented negative pregnancy test results for female participants required unless participant is menopausal without any spontaneous menstrual cycles for >12 months or key organs have been removed.)

5. Participant has HbA1C greater than 8.5 percent at screening
6. Participant has documented history in last 6 months of severe hypoglycemia associated with cognitive dysfunction sufficiently severe to require third party intervention or a history of impaired awareness of hypoglycemia.
7. Participant has a history of diabetic ketoacidosis in the last 6 months
8. Participant has known cardiovascular disease considered to be clinically relevant by the investigator
9. Participant has known arrhythmias considered to be clinically relevant by the investigator
10. Participant has known history of:

Summary
Brief summary
Over 1 million patients globally currently manage their Type 1 Diabetes mellitus using continuous subcutaneous insulin infusion with an infusion set that needs to be changed every 3 days. This study will assess the feasibility and device performance of the study device, the Achilles infusion set over three periods during routine insulin infusion.

This study will include 20 participants and has 3 periods:

Period 1 (up to 7 days): Trial run with study device with saline infusion. Period 2 (up to 7 days): participants will manage their blood glucose solely with their insulin pump and the Achilles infusion set. Blood glucose will be closely monitored with a continuous glucose monitoring (CGM) device.

Period 3 (up to 7 days): Participants will return to study center to receive a fresh Achilles infusion set and continue blood glucose management at home until infusion set failure or 7 days.
