indicative of system use (active closed loop) for at least 85% of the possible time in
14 days prior to enrollment
4. Total daily insulin dose (TDD) at least 2 U/day
5. HbA1c < 10.5%
6. Residing full-time in the United States, with no anticipated travel outside the United
States during the period of study participation.
7. For participants <18 years old, living with one or more parent/legal guardian
knowledgeable about emergency procedures for severe hypoglycemia and able to contact
the participant in case of an emergency, and willing to use the Dexcom Follow app
(with push notifications turned on) for the duration of the study.
8. If >18 years old, participant has someone who lives within 30 minutes of them who is
willing to be contacted if the study team can't reach the participant in case of a
suspected medical emergency.
9. Participant has agreed to participate in the study; and has read, understood and
signed the informed consent form (ICF) and assent, if applicable; and has agreed to
follow all study procedures, including:
1. suspending use of any personal CGM for the duration of the clinical trial once
the study CGM is in use
2. switching to or continuing to use Humalog during the lead-in period
3. switching to Lyumjev for the main study period.
4. willing and able to perform the study exercise and meal challenges.
10. Investigator has confidence that the participant can successfully operate all study
devices and is capable of adhering to the protocol, including ability to respond to
alerts and alarms, and to provide basic diabetes self-management.

English
Exclusion Criteria:

12. Use of glucocorticoids, beta blockers or other medications determined by investigator
to interfere with study
13. Abnormal screening electrocardiogram consistent with increased risk during exercise,
such as arrhythmia, ischemia, or prolonged QTc interval (>450 ms) (Screening ECG only
required for participants age > 50 years, duration of diabetes > 20 years, or history
of coronary artery disease)
14. Significant chronic kidney disease (which could impact CGM accuracy in investigator's
judgment) or hemodialysis
