Brief Summary

The purpose of this proposed study is to assess the use of a new feature of the Control-IQ system, MyTDI.

Detailed Description

This trial aims to demonstrate the safety and feasibility of using MyTDI to determine insulin parameters on the Closed Loop Control (CLC) Artificial Pancreas (AP) system t:slim X2 with Control-IQ tech...

Eligibility Criteria

Inclusion

  • Criteria for documented hyperglycemia (at least 1 must be met):
  • Clinical diagnosis of type 1 diabetes (C-peptide levels and antibody determinations are not required)
  • Diagnosis of type 1 diabetes is based on the investigator's judgement
  • Criteria for requiring insulin at diagnosis (both criteria must be met):
  • Daily insulin therapy for ≥ 6 months
  • Insulin pump therapy for ≥ 3 months
  • Age 12-18 years
  • Currently using no insulins other than one of the following rapid-acting insulins at the time of enrollment: insulin lispro (Humalog), insulin aspart (Novolog), or insulin glulisine (Apidra). If using glulisine, subject must be willing to switch to lispro or aspart.
  • Treatment with any non-insulin glucose-lowering agent (including GLP-1 agonists, Symlin, DPP-4 inhibitors, SGLT-2 inhibitors, biguanides, sulfonylureas, and naturaceuticals) is permitted if stable on current dose for at least 1 month.
  • Willingness to wear a continuous glucose sensor and physiological monitor for the duration of the study.
  • For females, not pregnant or breastfeeding. Female subjects who are sexually active should agree to use birth control during the study.
  • Total daily insulin dose (TDD) at least 10 U/day.

Exclusion

  • Diabetic ketoacidosis in the past 6 months
  • Hypoglycemic seizure or loss of consciousness in the past 6 months
  • History of seizure disorder
  • History of any heart disease including coronary artery disease, heart failure, or arrhythmias
  • History of altitude sickness
  • Chronic pulmonary conditions that could impair oxygenation
  • Cystic fibrosis
  • Current use of oral glucocorticoids, beta-blockers or other medications, which in the judgement of the investigator, would be a contraindication to participation in the study.
  • History of ongoing renal disease (other than microalbuminuria).
  • Subjects requiring intermediate or long-acting insulin (such as NPH, Detemir, or Glargine).
  • Pregnancy
  • Presence of a febrile illness within 24 hours of the Ski Admission
  • Medical or psychiatric conditions that in the judgement of the investigator might interfere with the completion of the protocol such as:
  • Inpatient psychiatric treatment in the past 6 months
  • Uncontrolled adrenal insufficiency
  • Alcohol abuse
