A Study to Evaluate Eli Lilly's Insulin Dosing Algorithm to Control Glycemia in Insulin-treated Adults With Type 2 Diabetes
Study Details
Study Description
Brief Summary
The objective of this study is to generate preliminary data in an inpatient setting to help optimize an insulin dosing logic (that decides how much to deliver insulin) for Eli Lilly's system.

N/A |
Detailed Description
After being informed about the study and potential risks, all participants giving written informed consent will undergo an admission visit to determine eligibility for study entry. Participants who meet the inclusion and exclusion criteria will then participate in two 41-hour intervention visits using Eli Lilly's insulin dosing algorithm.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Other: Insulin alone closed-loop
|
Other: Insulin closed-loop
41-hour intervention period in which the participants are treated with rapid insulin in the closed-loop system.

Outcome Measures
Primary Outcome Measures
- Glucose outcomes: percentage of time spent in specific glucose ranges (ex: 3.9-10.0 mmol/L) [24 hours]
As this is a pilot study, the only primary outcome is the glucose outcomes during the closed-loop portion.
Eligibility Criteria
Criteria
Inclusion Criteria:
To be eligible for the study, all participants must meet the following criteria:
-
Adult male or female ≥ 18 years of age.
-
Type 2 diabetes mellitus has been clinically diagnosed (the diagnosis of type 2 diabetes is based on the investigator's judgment) for at least 12 months
-
Using multiple daily insulin injections (one basal and ≥ 2 prandial doses) for ≥ 3 months.
-
Using insulin glargine (U100 or U300), detemir, degludec, or NPH.
-
Most recent (in the last 6 month) HbA1c ≤ 10%.
-
Use of a GLP1 agonist or SGLT inhibitor for the past 3 months.
Exclusion Criteria:
Participants who meet any of the following criteria are not eligible for the study:
-
Severe hypoglycaemic episode ≤ two months before admission.
-
Ongoing pregnancy, or any newly diagnosed pregnancy throughout the study
-
Clinically significant nephropathy, neuropathy or retinopathy as judged by the investigator.
-
Recent (within the past 6 months) acute macrovascular event (e.g. acute coronary syndrome or cardiac surgery).
-
Peripheral vascular disease, foot ulcer, Charcot arthropathy or any condition that limits ability to walk
-
Other serious medical illness likely to interfere with study participation or with the ability to complete the trial by the judgment of the investigator.
-
Use of oral hypoglycaemic agents besides SGLTi's, GLP1 agonists, and or metformin and unwilling to discontinue for the run-in and intervention period.
