Could a metabolic modulator help people with type 1 diabetes use insulin better?

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

Inclusion Criteria: 1. Adults ≥18 years to \<70 years of age with established T1D (duration ≥1 year) 2. Currently on insulin therapy (multiple daily injections or insulin pump) 3. HbA1c \<9.5% 4. BMI 18.5-40 kg/m2 5. On stable dose of RASB or statin, if indicated 6. Willing and able to comply with all study procedures Exclusion Criteria: 1. History of pancreatic disease (including pancreatitis) or pancreatic surgery 2. History of cardiovascular disease or stroke within the past 6 months 3. History of heart failure per New York Heart Association criteria 4. History of severe edema or salt restriction requirement 5. Biliary disease or pathologies that may alter enterohepatic circulation of bile acids 6. Estimated glomerular filtration rate (eGFR) \<60 mL/min/1.73m² 7.

Abnormal baseline ECG 11. Use of off label medications that affect insulin sensitivity within the past 1 month (e.g., metformin, GLP-1RA, SGLT2i, pioglitazone) 12. Chronic use of anticoagulants 13. Use of bile acid sequestering agents, inhibitors of bile acid transporters, bile acid derivatives, aluminum-based antacids, probenecid, pan-HDAC inhibitors, phase 2 metabolizing enzymes (e.g., uridine diphosphate glucuronosyl transferases), phase 1 metabolizing enzymes other than cytochrome P450 enzymes (CYPs), and OATP1B3 14. Use of substrates of CYP1A2, CYP2C8, CYP2B6, CYP3A4, Organic Anion transporter 1, P-glycoprotein, and Breast Cancer Resistance Protein 15. History of severe hypoglycemia requiring assistance within the past 3 months 16. History of diabetic ketoacidosis (DKA) within the past 3 months 17. Personal or family history of breast cancer or ovarian cancer 18. Current participation in another clinical trial 19. Any condition(s) found by the study team and confirmed with the Investigator that make it unsafe to participate
