NCT07211126

Brief Summary

This post-market surveillance study is primarily designed to demonstrate the ongoing safety of the Control-IQ system, the ongoing performance of glycemic control and quality of life with Control-IQ system use, and the rate of use of the Control-IQ system. The system will be assessed in all approved populations during the first 12 months of use.

Outcome Measures

Primary Outcomes (2)

  • Rate of diabetic ketoacidosis (DKA).

    The incidence rate of diabetic ketoacidosis (DKA) will be calculated by dividing the total number of events observed in the entire cohort over the 12-month follow-up period. Results will be expressed as the number of events per 100 patient-years.

    12 months

  • Rate of severe hypoglycemia (SH)

    The incidence rate of severe hypoglycemia (SH) will be calculated by dividing the total number of events observed in the entire cohort over the 12-month follow-up period. Results will be expressed as the number of events per 100 patient-years.

    12 months

Secondary Outcomes (10)

  • Time in Range 70-180 mg/dL (TIR)

    12 months

  • Time above 180 mg/dL

    12 months

  • Time above 250 mg/dL

Study Arms (1)

Control-IQ System

Participants will use the Control-IQ System as per standard of care.

Device: t:slim X2 insulin pump with Control-IQ technology (Control-IQ System)

Interventions

Participants enrolled in the study will start use of the t:slim X2 insulin pump with Control-IQ technology (Control-IQ System) with Dexcom G6 or Dexcom G7, and be followed for 12 months.

Sampling MethodNon-Probability Sample
Study Population

All individuals with Type 1 Diabetes age 6+, who start therapy with the t:slim X2 insulin pump with Control-IQ technology (Control-IQ System) with a Dexcom G6 or Dexcom G7 and meet eligibility criteria.

You may qualify if:

  • Clinician-confirmed type 1 diabetes and for whom the site has initiated the t:slim X2 insulin pump with Control-IQ technology (Control-IQ System) with a Dexcom G6 or G7 CGM sensor.
  • Age ≥ 6 years at enrollment.
  • Using an insulin approved for use in the pump.
  • Ability for patient or parent/guardian to respond to alerts and alarms, and to provide basic diabetes self-management.
  • Reside full-time in mainland France.
  • Have an email address and mobile phone number
  • Participant or participant's parent/guardian has read and understood the information notice and has agreed to participate in the study. This includes agreeing to :
  • use Control-IQ technology, and to continue use for at least 12 consecutive months after study enrollment.
  • the reuse of their clinical data including HbA1c results, obtained at most 4 months prior to enrollment, and as available according to the standard of care during the next 12 months.
  • complete questionnaires per the study protocol.

You may not qualify if:

  • 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.
  • Patients considered vulnerable under French law.
