Add-on Combination Therapy with Insulin (with or without Metformin)
In an 18-week randomized, double-blind, multi-center, placebo-controlled, glycemic sub-study of VERTIS CV (eValuation of ERTugliflozin efficacy and Safety CardioVascular, NCT01986881, study details see 14.2), a total of 1065 patients with type 2 diabetes mellitus and established atherosclerotic cardiovascular disease with inadequate glycemic control (HbA1c between 7% and 10.5%) on background therapy of insulin ≥20 units/day (59% also on metformin ≥1,500 mg/day) were randomized to placebo, STEGLATRO 5 mg or STEGLATRO 15 mg once daily treatment.
At Week 18, treatment with STEGLATRO at 5 mg or 15 mg daily provided statistically significant reductions in HbA1c compared to placebo (see Table 8).

The mean baseline body weights were 93.3 kg, 93.8 kg, and 92.1 kg in the placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg groups, respectively. The mean changes from baseline to Week 18 were - 0.2 kg, -1.6 kg, and -1.9 kg in the placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg groups, respectively. The differences from placebo (95% CI) for STEGLATRO 5 mg were - 1.4 kg (- 1.9, - 0.9) and for STEGLATRO 15 mg was -1.6 kg (-2.1, -1.1).
The mean baseline systolic blood pressures were 134.0 mmHg, 135.6 mmHg, and 133.7 mmHg in the placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg groups, respectively. The mean changes from baseline to Week 18 were 0.7 mmHg, -2.2 mmHg, and -1.7 mmHg in the placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg groups, respectively. The differences from placebo (95% CI) for STEGLATRO 5 mg was – 2.9 mmHg (-4.9, -1.0) and for STEGLATRO 15 mg were -2.5 mmHg (- 4.4, - 0.5).
Add-on Combination Therapy with Metformin and Sulfonylurea
In an 18-week randomized, double-blind, multi-center, placebo-controlled, glycemic sub-study of VERTIS CV (NCT01986881, study details see 14.2), a total of 330 patients with type 2 diabetes mellitus and established atherosclerotic cardiovascular disease with inadequate glycemic control (HbA1c between 7% and 10.5%) with background therapy of metformin ≥1,500 mg/day and a sulfonylurea (SU) were randomized to placebo, STEGLATRO 5 mg or STEGLATRO 15 mg once daily treatment.
At Week 18, treatment with STEGLATRO at 5 mg or 15 mg daily provided statistically significant reductions in HbA1c compared to placebo (see Table 9).

The mean baseline body weights were 90.5 kg, 92.1 kg, and 92.9 kg in the placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg groups, respectively. The mean changes from baseline to Week 18 were - 0.6 kg, -2.0 kg, and - 2.2 kg in the placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg groups, respectively. The differences from placebo (95% CI) for STEGLATRO 5 mg were - 1.4 kg (- 2.2, - 0.7) and for STEGLATRO 15 mg was - 1.6 kg (- 2.3, - 0.9).
Use in Patients with Type 2 Diabetes Mellitus and Moderate Renal Impairment
26-Week Placebo-Controlled Study
The efficacy of STEGLATRO was assessed in a multicenter, randomized, double-blind, placebo-controlled study (NCT01986855) of patients with type 2 diabetes mellitus and moderate renal impairment (468 patients with eGFR ≥30 to <60 mL/min/1.73 m2). In this study, 202 patients exposed to STEGLATRO (5 mg or 15 mg) had an eGFR between 45 and 60 mL/min/1.73 m2 and 111 patients exposed to STEGLATRO (5 mg or 15 mg) had an eGFR between 30 and 45 mL/min/1.73 m2. The mean duration of diabetes for the study population was approximately 14 years, and the majority of patients were receiving background insulin (55.9%) and/or sulfonylurea (40.3%) therapy. Approximately 50% had a history of cardiovascular disease or heart failure.
STEGLATRO did not show efficacy in this study. The HbA1c reductions from baseline to Week 26 were not significantly different between placebo and STEGLATRO 5 mg or 15 mg [see Use in Specific Populations (8.6)].
