Study Arms (1)

Control-IQ Technology v1.5

Real-world use of Control-IQ technology v1.5 for 12 months.

Device: Control-IQ Technology v1.5

Interventions

Tandem t:slim X2 insulin pump or Tandem Mobi insulin pump with Control-IQ technology v1.5. Every month participants will receive a survey to complete assessments including any severe hypoglycemia or diabetic ketoacidosis events experienced since the prior assessment. Participants will also complete surveys related to patient reported outcomes at baseline, 6 months, and 12 months.

Study Population

Enrollment in the study will be available to all individuals age 2 to \<6 years of age at time of screening who start therapy with Control-IQ Technology v1.5.

You may qualify if:

  • Self-reported type 1 diabetes who have been prescribed the Control-IQ 1.5 system in the t:slim X2 or Mobi insulin pump
  • Age 2 to \<6 years at time of screening
  • Using an insulin approved for use in the pump
  • Using an iCGM sensor approved for use with the pump
  • Agreement to use Control-IQ technology 1.5, and to continue use for at least 12 consecutive months after study enrollment.
  • Agree to provide HbA1c result, obtained within the 6-month period prior to enrollment.
  • Ability for parent/guardian to respond to alerts and alarms, and to provide basic diabetes self-management.
  • Reside full-time in the United States.
  • Willingness to download the t:connect Mobile application to their smartphone and keep it active throughout the study if using a Tandem t:slim X2 pump. Participants who are unable to use the t:connect mobile application must be willing to manually upload their insulin pump data to Tandem Source every three months and at the completion of the study.
  • Participant's parent/guardian has read, understood and agreed to participate in the study, and has electronically signed the Informed Consent Form (ICF).

You may not qualify if:

  • Use of any glucose-lowering therapy other than insulin.
  • A medical or other condition, or medications being taken that in the investigator's judgement would be a safety concern for participation in the study.
