Observational, Data Collection Study for Subjects With Diabetes Using Insulin Injections

Study Overview
=================
Brief Summary
-----------------
This is an observational, multicenter prospective study including up to 260 subjects with type 1 or type 2 diabetes who use insulin injections (either basal insulin only or multiple daily injections (MDI)) and CGM or SMBG to manage their diabetes. The study aims to generate the database needed for future development and verification of insulin-glucose modules of subjects with diabetes using insulin injections. During the study, subjects will continue their regular diabetes management using their regular glucose monitoring method (either CGM or SMBG), insulin injections and oral medication (as applicable). Subjects will be requested to document glucose levels and insulin delivery during basal only or basal/bolus insulin treatment. In addition, subjects will have their daily activities recorded (meals, physical activity etc) using electronic log (implemented on the CGM/FGM receiver, Dedicated App, Neura App and/or other logbooks). Data will be captured during regular daily life using Insulin Connected pens and daily diary application software, for a period of 1 month.

Eligibility Criteria
-----------------
Inclusion Criteria: Documented T1D or T2D for at least 1 year prior to study enrolment T1D: Subjects aged 1 year or older T2D: Subjects aged 30 years or older A1c at inclusion ≤ 10% Subjects using basal-bolus MDI therapy or basal insulin only - basal insulin Lantus or Tregludec and any short acting insulin. T2D: Insulin pumps will also be accepted. T2D: BMI ≥ 25 kg/m2 Subjects willing to follow study instructions: For SMBG users: measure capillary blood glucose at least 4 times a day and twice a week 7-point profile. Document blood glucose level, insulin delivery, meals and daily activities. Optional: wear blinded CGM. For CGM users: Document insulin delivery, meals and daily activities. Optional: Measure capillary blood glucose in addition. Adult subjects or parents of pediatric subjects willing and able to sign a written informed consent form. Exclusion Criteria: An episode of diabetic keto-acidosis within the month prior to study entry and/or severe hypoglycemia resulting in seizure or loss of consciousness in the month prior to enrolment. Concomitant diseases/ treatment that influence metabolic control (except diabetes treatment for T2) or any significant diseases /conditions including psychiatric disorders and substance abuse that in the opinion of the investigator is likely to affect the subject's ability to complete the study or compromise subject's safety T2D: eGFR < 60 Participation in any other interventional study Female subject who is pregnant or planning to become pregnant within the planned study duration T1D: Subject is in the honeymoon phase - i.e. less than 0.5 insulin units/kg per day.
