New automated insulin system tested for hospital diabetes care

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Have had a diagnosis of type 1 or type 2 diabetes for a period of at least 3 months. 4. Use insulin injections at home for glucose control. 5. Have a hemoglobin A1c (HbA1c) in the range of 7.0 - 10.0%. 6. Have a hemoglobin in the range for sex: 1. Females: 7-15.5 grams/dL. 2. Males: 7-17.5 grams/dl. 7.

Have skin disease/injury at Dexcom G6 CGM insertion site(s) that would prevent insertion of the CGM. 4. Currently abuses drugs or alcohol or has a history of abuse that in the investigator's opinion would cause the individual to be noncompliant. 5. Have a medical condition that in the opinion of the investigator could affect study participation and/or personal well-being. 6. Have a clinically significant history or presence of any of the following conditions: 1. Hepatic failure or has alanine aminotransferase (ALT) greater than 3 times the upper limit of normal. 2. Has an estimated GFR \<30 ml/min/1.73 m2 or End Stage Kidney Disease on renal replacement therapy. 3. Have congestive heart failure greater than class 1 on the NYHA classification system. 4. Have a history of seizures. 5. Have a history of cerebrovascular accident. 6. Have a history of ischemic heart disease. 7. For female subjects of potential childbearing age (age 18 to 55) they will be excluded if: 1. Pregnant. 2. Refuse to agree to a pregnancy test at the time of enrollment. 3.

Have a known unprotected Influenza or COVID exposure in the 14-day period prior to visit 3. 11. Are currently being treated with Hydroxyurea, a medication which may cause the Dexcom G6 CGM to produce glucose readings that are higher than the actual glucose value.
