Lexicon Pharmaceuticals Presents Clinical Data at 80th American Diabetes Association Scientific Sessions
THE WOODLANDS, Texas, June 13, 2020 (GLOBE NEWSWIRE) -- (Nasdaq: LXRX), today presented six posters for ZynquistaTM (sotagliflozin) at the virtual 80th American Diabetes Association (ADA) Scientific Sessions including additional efficacy and safety data patients with type 2 diabetes and moderate and severe renal impairment.
Phase 3 CKD-3 Study
In the Phase 3, multicenter, randomized, double-blind, placebo-controlled CKD-3 study, sotagliflozin was tested for superiority versus placebo in reducing A1C after 26 weeks of treatment in patients with type 2 diabetes, inadequate glycemic control and moderate (CKD Stage 3) renal impairment.
The study met its primary endpoint, demonstrating that sotagliflozin 400 mg significantly reduced A1C in the entire population of patients with moderate renal impairment compared to placebo at Week 26. The difference in least squares (LS) mean change in A1C from baseline for patients treated with sotagliflozin 400 mg compared to placebo was -0.24% (p = 0.0021). The change in A1C from baseline was not statistically different in patients treated with sotagliflozin 200 mg compared to placebo (p = 0.2085).
The safety profile of sotagliflozin was generally similar to that of placebo. Incidences of symptomatic hypoglycemia (with documented blood glucose ≤70 mg/dL) were 20.4% on sotagliflozin 400 mg, 27.3% on sotagliflozin 200 mg, and 25.0% on placebo. The rates of symptomatic hypoglycemia (per 100 patient years of exposure) were 114.0 on sotagliflozin 400 mg, 140.5 on sotagliflozin 200 mg, and 175.4 on placebo.
Phase 3 CKD-4 Study
In the Phase 3, multicenter, randomized, double-blind, placebo-controlled CKD-4 study, sotagliflozin was tested for superiority versus placebo in reducing A1C after 26 weeks of treatment in patients with type 2 diabetes, inadequate glycemic control and severe (CKD Stage 4) renal impairment.
The study did not meet its primary endpoint of demonstrating superiority of sotagliflozin versus placebo on A1C reduction after 26 weeks of treatment in patients with type 2 diabetes, inadequate glycemic control and severe renal impairment compared to placebo. The placebo-adjusted difference in A1C from baseline for patients treated with sotagliflozin 400 mg compared to placebo was -0.29% (p = 0.0962) at week 26. For sotagliflozin 200 mg, the placebo-adjusted difference in A1C was 0.05% (p = 0.8124).
Several findings indicated clinically meaningful glycemic control over time was achieved with sotagliflozin 400 mg. From baseline to Week 52, the placebo-subtracted A1C reduction for sotagliflozin 400 mg was -0.69% (95% confidence interval: -0.23, -1.15). At Week 52, achievement of A1C ≤ 7% was seen in 20.7% of patients on sotagliflozin 400 mg compared to 6.5% on placebo. Over 52 weeks, the incidence of rescue therapy to treat hyperglycemia was 7.6% on sotagliflozin 400 mg and 15.1% on placebo. Results were consistent with a dose related-response, as the 200 mg dose group at Week 52 had a placebo-subtracted A1C reduction of -0.32%, 19.6% of patients achieved A1C ≤ 7%, and 10.9% required rescue therapy.
The safety profile of sotagliflozin was generally similar to that of placebo. This was a population at high cardiovascular risk, and the incidences of major adverse cardiovascular events (myocardial infarction, stroke, and cardiovascular death) were 4.4% on sotagliflozin 400 mg, 1.1% on sotagliflozin 200 mg, and 11.9% on placebo. Incidences of symptomatic hypoglycemia (with documented blood glucose ≤70 mg/dL) were 27.8% on sotagliflozin 400 mg, 28.7% on sotagliflozin 200 mg and 35.5% on placebo, and the rates (per 100 patient years of exposure) were 171.6 on sotagliflozin 400 mg, 226.9 on sotagliflozin 200 mg, and 269.8 on placebo.

About Sotagliflozin
Discovered using Lexicon’s unique approach to gene science, sotagliflozin is an oral dual inhibitor of two proteins responsible for glucose regulation known as sodium-glucose co-transporter types 1 and 2 (SGLT1 and SGLT2). SGLT1 is responsible for glucose absorption in the gastrointestinal tract, and SGLT2 is responsible for glucose reabsorption by the kidney. Sotagliflozin is approved in the European Union (EU) for use as an adjunct to insulin therapy to improve blood sugar (glycemic) control in adults with type 1 diabetes with a body mass index ≥ 27 kg/m2, who could not achieve adequate glycemic control despite optimal insulin therapy.
