Evaluate safety of non-adjunctive CGM use in CGM naive participants.

The study comprises recruitment and consenting of pediatric and adult participants. At entry, the following information will be collected: demographics, labs, clinical and diabetes history information (history of mild/severe hypoglycemia or DKA events in the past 6 months and SMBG testing frequency). There are 3 clinic visits: Study Entry, Month 6 and Month 12 . Monthly phone contacts will be made to assess for any mild/severe hypoglycemic or DKA events and any details surrounding an event. Clinic visits at Months 6 and 12 will capture frequency of SMBG testing, A1C level and PRO information. CGM data will be obtained during the study to assess for CGM adherence.
