A Phase 2, Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy and Safety of LX4211 in Young Adult Patients With Type 1 Diabetes Mellitus and Elevated Hemoglobin A1C

This Phase 2 study was intended to demonstrate superiority of sotagliflozin versus placebo on Hemoglobin A1C (A1C) reduction at Week 12 in young adult participants with type 1 diabetes mellitus (T1DM) who have poor glycemic control on their current insulin regimen.

• Participant had given written informed consent.
• Young adult participants >=18 to <=30 years old at Screening, with a confirmed diagnosis of T1DM made at least 1 year prior to informed consent.
• Participants were being treated with insulin or insulin analogue delivered via continuous subcutaneous insulin infusion (CSII) or multiple daily injections (MDI).
• At Screening, must had A1C >= 9.0%.
• Must be willing and able to perform self-monitored blood glucose (SMBG) and complete the study diary.
• Females of childbearing potential must use an adequate method of contraception and had a negative pregnancy test.

Exclusion Criteria:

• Any prior use of LX4211/sotagliflozin.
• Use of antidiabetic agent other than insulin or insulin analogue at the time of screening.
• Use of sodium-glucose cotransporter (SGLT) inhibitors within 8 weeks prior to start of the placebo Run-in Period.
• Chronic systemic corticosteroid use.
• Type 2 diabetes, or severely uncontrolled diabetes mellitus as determined by the Investigator.
• History of diabetic ketoacidosis (DKA) or nonketotic hyperosmolar state within 6 months prior to the Screening Visit.
