Exclusion Criteria: 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; History of pancreatitis, medullary thyroid carcinoma or liver disease; Clinically significant diagnosis of anemia (Hemoglobin < 9 g/dl at screening); Body Mass Index (BMI) < 18.5 kg/m2 and/or weight <50kg; Body Mass Index (BMI) > 35 kg/m2 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; Current or recent (within 1 month of screening) use of diabetes medications other than insulin; (examples include GLP-1 RA, SGLT-2i, Pramlintide, Metformin); Women who are pregnant or lactating/breastfeeding; Unable or unwilling to follow the study protocol or who are non-compliant with screening appointments or study visits; 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.

Each participant will receive 12-week insulin-adjunctive treatment with both: (1) SGLTi (sotagliflozin 200 mg PO each day) + Placebo and (2) SGLTi + GRA (volagidemab 35 mg subcutaneously each week), in a random-order, cross-over design with a 14-week washout period between treatment periods. Sotagliflozin is a dual sodium-glucose co-transporter-1 and sodium-glucose co-transporter-2 (SGLT1/2) inhibitor.
