Prior treatment

• Currently using beta-blockers;

Other illness

• History or evidence of clinically significant disorder or condition that, in the opinion of the Investigator, would pose a risk to subject safety or interfere with the study evaluation, procedures, or completion;

• Current or recent (within 1 month of screening) use of diabetes medications other than insulin; (examples include GLP-1, RA, SGLT-2i, Pramlintide, Metformin);
• Any other condition(s) that might reduce the chance of obtaining study data, or that might cause safety concerns, or that might compromise the ability to give truly informed consent;
• Adrenal insufficiency diagnosis.

Lab values

• Clinically significant diagnosis of anemia (Hemoglobin \< 9 g/dl at screening);
• Whole blood donation of 1 pint (500 mL) within 8 weeks prior to Screening. Donations of plasma, packed RBCs, platelets or quantities less than 500 mL are allowed at investigator discretion;

• Severe hypoglycemic events or DKA within 3 months;

• Men and women between the ages of 18 and 75 years old, inclusive, at the time of screening;
• Females of non-childbearing potential must be ≥ 1 year post-menopausal or documented as being surgically sterile. Females of childbearing potential must agree to use two methods of contraception during the entire study;

• Using hybrid closed loop, standard pump, or multiple daily injections;
• Able to use a Continuous Glucose Monitoring (CGM) device;
• A1c \> 7% and ≤ 10%:
