Medtronic CIP335 study for Type I Diabetes

  • Study HIC#:2000032795
  • Last Updated:07/21/2023

Are you currently living with Type 1 Diabetes?

Yale University is performing a study evaluating the use of Lyumjev insulin, in the MiniMed 780G Insulin Pump from Medtronic. Lyumjev is a rapid acting mealtime insulin with a faster onset of action when compared to Humalog. After a run-in period using the MiniMed 780G pump with your usual insulin (either Humalog, Novolog, or Admelog), participants will use the MiniMed 780G pump and Lyumjev insulin for 3 months.

You may qualify if you are…

  • Between the ages of 7-17
  • Have an A1c level less than 10%
  • You have been using insulin pump therapy for at least 6 months

The study requires several in-person visits to Yale in New Haven and 2 blood tests at the beginning and end of the study. We may be able to provide additional financial support for transportation if you live a significant distance from Yale. Compensation is $75-$125 for office/virtual visits and $30 for telephone visits.
