Efficacy and Bone Safety of Sotagliflozin 400 and 200 mg Versus Placebo in Participants With Type 2 Diabetes Mellitus Who Have Inadequate Glycemic Control

The primary objective is to demonstrate the superiority of Sotagliflozin 400 milligrams (mg) versus placebo with respect to hemoglobin A1c (Hb1Ac) reduction in participants with type 2 diabetes (T2D) who have inadequate glycemic control on diet and exercise only or with a stable antidiabetes regimen.

Study duration per participant is approximately 110 weeks (Screening period of up to 2 weeks, 2 week single-blind run-in period), a 26-week double-blind core treatment period, a 78-week double-blind extension period, and a 2- week post treatment follow up period.

Dual-energy X-ray absorptiometry (DXA) scans will be performed to assess Bone Mineral Density and Fat vs. Lean body mass at baseline and Weeks 26, 52, and 104.

Eligibility Criteria:
Inclusion criteria :

* Participants with T2D managed with diet and exercise only or with a stable antidiabetes regimen (in monotherapy or combination therapy that can include oral antidiabetes medications, insulin, or glucagon-like peptide-1 agonists) for more than 12 weeks.
* Participants has given written informed consent to participate in the study in accordance with local regulations.

Exclusion criteria:

* Age \<55 years.
* Women who have been postmenopausal (or undergone bilateral oophorectomy) for less than 5 years.
* Type 1 diabetes mellitus.
* Body mass index (BMI) ≤20 or \>45 kilogram per meter square kg/m\^2 or bodyweight that exceeds the weight limits of the DXA scanner.
* Hemoglobin A1C (HbA1c) \<7.0% or HbA1c \>11.0%.
* Use of a selective sodium-glucose cotransporter type 2 (SGLT2) inhibitor or thiazolidinedione within 24 months.
* Bone mineral density (BMD) T- score \<-2.0 at any site (ie, lumbar spine, total hip, or femoral neck).
* History of fracture within 12 months (except for fractures of the hand/fingers, foot/toes, facial bones, and skull).
* Treatment with medications known to affect bone mass or modify the risk of fractures within 36 months (eg, bisphosphonates, selective estrogen receptor modulators, calcitonin, teriparatide, denosumab, strontium ranelate, growth hormone, aromatase inhibitors, androgen deprivation therapy, carbamazepine, phenytoin, and phenobarbital). Use of hormonal replacement that includes systemic or transdermal estrogen or testosterone is excluded unless is stable for at least 24 months prior to Screening.
* Lower extremity complications (such as skin ulcers, infection, osteomyelitis and gangrene) identified during the Screening period, and still requiring treatment at randomization.
* Uncontrolled high blood pressure, severe anemia, severe cardiovascular problems, such as heart failure, active cancer, or other conditions that the Investigator believes with result in a short life expectancy.
* Renal disease as defined by an estimated glomerular filtration rate (eGFR) \<30 milliliter per minute (mL/min)/1.73 meter square (m\^2) at the Screening Visit by the 4 variable Modification of Diet in Renal Disease equation.
