Efficacy and Safety of Sotagliflozin Versus Placebo in Participants With Type 2 Diabetes Mellitus Who Have Inadequate Glycemic Control While Taking Insulin Alone or With Other Oral Antidiabetic Agents

• Status: Completed
• Trial end date: 2019-09-27
• Target enrollment: 0
• Participant gender: All

Summary

Primary Objective:

To demonstrate the superiority of sotagliflozin 400 milligrams (mg) versus placebo with respect to hemoglobin A1C (HbA1c) reduction in participants with type 2 diabetes mellitus (T2D) who have inadequate glycemic control on basal insulin alone or with oral antidiabetes drugs (OADs).

Secondary Objectives:

• To assess the effects of sotagliflozin 400 mg versus placebo on fasting plasma glucose (FPG), body weight, systolic blood pressure (SBP), and HbA1c.

• To assess the effects of sotagliflozin 200 mg versus placebo on HbA1c, body weight, FPG, and SBP.

• To evaluate the safety of sotagliflozin 400 and 200 mg versus placebo.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Criteria

Inclusion criteria :

• Participants with Type 2 Diabetes Mellitus (T2DM) using any types of basal insulin alone or in combination with up to 2 OADs.

• Participants have given written informed consent to participate in the study in accordance with local regulations.

Exclusion criteria:

• At the time of Screening age <18 years orgreater.

• Type 1 diabetes mellitus.

• Oral antidiabetic drugs dose not stable for 8 weeks before Screening.

• Use of basal insulin therapy (e.g., insulin glargine, Neutral Protamine Hagedorn (NPH), detemir, or degludec) for less than 6 months before Screening.

• Dose of basal insulin (e.g., insulin glargine, NPH, detemir, or degludec) not stable for 8 weeks before Screening (i.e., total daily insulin dose increased or decreased by more than 20%).

• Known unstable proliferative diabetic retinopathy or any other rapidly progressive diabetic retinopathy or macular edema that is likely to require laser, surgical treatment during study period.

• Use of injectable diabetes drugs other than basal insulin (e.g., insulin glargine, NPH, detemir, or degludec), i.e., prandial or rapid-acting insulins, short-acting insulins, glucagon-like peptide 1 (GLP-1) receptor agonists, or inhaled prandial insulin (Afrezza) within 8 weeks of Screening.

• Use of a selective sodium-glucose cotransporter type 2 (SGLT2) inhibitor (e.g., canagliflozin, dapagliflozin, or empagliflozin) within 3 months prior to the trial.

• Use of systemic glucocorticoids (excluding topical, intra articular, or ophthalmic application, nasal spray or inhaled forms) for more than 10 consecutive days within 90 days prior to the Screening Visit.

• Participants with severe anemia, severe cardiovascular (including congestive heart failure New York Heart Association IV), respiratory, hepatic, neurological, psychiatric, or active malignant tumor or other major systemic disease that, according to the Investigator, will preclude their safe participation in this study, or will make implementation of the protocol or interpretation of the study results difficult.

• Lower extremity complications (such as skin ulcers, infection, osteomyelitis and gangrene) identified during the Screening period, and still requiring treatment at Randomization.

• Known presence of factors that interfere with the Central Lab HbA1c measurement (e.g., genetic hemoglobin (Hb) variants) compromising the reliability of HbA1c assessment or medical conditions that affect interpretation of HbA1c results (e.g., blood transfusion or severe blood loss in the last 3 months prior to randomization, any condition that shortens erythrocyte survival).

• Participants who has taken other investigational drugs or prohibited therapy for this study within 12 weeks or 5 half-lives from prior to Screening, whichever is longer.

• Participants unwilling to perform self-monitoring of blood glucose (SMBG), complete the patient diary, or comply with study visits and other study procedures as required per protocol.

• HbA1c <7.5% or HbA1c >10.5% measured by the central laboratory at Screening.

• HbA1c <7% measured by the central laboratory at Visit 5 (Week -1).

• History of diabetic ketoacidosis or nonketotic hyperosmolar coma within 12 weeks prior to the Screening Visit.

• Pregnant (confirmed by serum pregnancy test at Screening) or breastfeeding women.

• Women of childbearing potential not willing to use highly effective method(s) of birth control during the study treatment period and the follow-up period, or who are unwilling or unable to be tested for pregnancy during the study.

• Mean of 3 separate blood pressure measurements >180 mmHg (systolic blood pressure [SBP]) or >100 mmHg (diastolic blood pressure [DBP]).

• History of gastric surgery including history of gastric banding or inflammatory bowel disease within 3 years prior to the Screening Visit.

• Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) >3 times the upper limit of the normal laboratory range

• Total bilirubin >1.5 times the upper limit of the normal laboratory range (except in case of Gilbert's syndrome).
