Recruitment status

TERMINATED

Study phase

NA

Target enrollment

22 participants

Primary outcome timeframe

1 day (last day of each study arm - exercise visit)

Participant Flow

22 subjects signed the consent form and screened into the study. 5 subjects were randomized and participated in the outpatient run-in period for one arm. Only 2 subjects of those 5 completed the arm. No subjects completed both arms of the study.

Measure
Bihormonal Bionic Pancreas First, Then Insulin-Only
Insulin-only bionic pancreas exercise visit - subjects will participate in the outpatient bionic pancreas run in period, and will use the insulin-only bionic pancreas for their exercise visit at the end of the run in. The glucagon pump of the bionic pancreas will be filled with placebo (normal saline). Placebo: Placebo will be given instead of glucagon according to the algorithm in the insulin-only bionic pancreas Bihormonal bionic pancreas exercise visit - subjects will participate in the outpatient bionic pancreas run in period, and will use the bihormonal bionic pancreas for their exercise visit at the end of the run in. The glucagon pump of the bionic pancreas will be filled with glucagon. Glucagon: Glucagon will be given according to the algorithm in the bihormonal bionic pancreas

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 1 day (last day of each study arm - exercise visit)

Population: The study was terminated without performing any analysis of the data. The study was terminated because of a lack of appropriate funding.
