The sodium glucose cotransporter 2 (SGLT2) inhibitors canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin represent a novel class of medications to manage type 2 diabetes through urinary excretion of glucose. These drugs block glucose reabsorption by the kidneys to increase glucosuria. These drugs provide hemoglobin A1C reduction, promote weight loss, and remain hypoglycemic-neutral when not used in combination with insulin or secretagogues. Canagliflozin and empagliflozin have shown cardiovascular benefit. The potential to reduce the risk of cardiovascular death in patients with type 2 diabetes, along with the benefit of weight reduction, makes these new agents useful tools for the primary care provider.

We evaluated the efficacy and safety of ertugliflozin, an SGLT2 inhibitor, in type 2 diabetes mellitus (T2DM) inadequately controlled (HbA1c, 7.0%-10.5%) with metformin monotherapy (≥1500 mg/d for ≥8 weeks).. This was a double-blind, 26-week, multicentre study with ongoing 78-week extension (ClinicalTrials.gov identifier: NCT02033889). A total of 621 participants were randomized 1:1:1 to placebo, or ertugliflozin 5 or 15 mg/d. The primary endpoint was change from baseline at week 26 in HbA1c. Secondary efficacy endpoints were change from baseline at week 26 in fasting plasma glucose (FPG), body weight, systolic/diastolic blood pressure (SBP/DBP) and number of participants with HbA1c <7.0% (53 mmol/mol). Pre-specified adverse events (AEs) of special interest and percent change from baseline in bone mineral density (BMD) were also assessed at week 26.. At week 26, the placebo-adjusted least-squares mean change from baseline HbA1c (8.1%) was -0.7% and -0.9% for ertugliflozin 5 and 15 mg, respectively (both P < .001), to final means of 7.3% and 7.2%, respectively. The odds of HbA1c <7.0% were significantly greater in both ertugliflozin groups vs placebo. Ertugliflozin significantly reduced FPG, body weight, SBP and DBP vs placebo. The incidence of genital mycotic infections was higher in the ertugliflozin groups (female subjects: placebo, 0.9%; ertugliflozin 5 mg, 5.5%; ertugliflozin 15 mg, 6.3% [P = .032]; male subjects: 0%; 3.1%; 3.2%, respectively), as was the incidence of urinary tract infections and symptomatic hypoglycaemia. The incidence of hypovolaemia AEs was similar across groups. Ertugliflozin had no adverse impact on BMD at week 26.. Ertugliflozin added to metformin in patients with inadequately controlled T2DM improved glycaemic control, reduced body weight and BP, but increased the incidence of genital mycotic infections.

This phase III, multicentre, randomized study (ClinicalTrials.gov; NCT01958671) evaluated the efficacy and safety of ertugliflozin monotherapy in adults with inadequately controlled type 2 diabetes (glycated haemoglobin [HbA1c], 7.0% to 10.5% [53-91 mmol/mol]) despite diet and exercise.. The 52-week study comprised a 26-week, double-blind, placebo-controlled period (Phase A) during which 461 participants received placebo, ertugliflozin 5 mg/d or ertugliflozin 15 mg/d. This was followed by a 26-week active-controlled period (Phase B) during which participants in the placebo group who had not received glycaemic rescue therapy had blinded metformin added. Results to Week 52 are reported. Because of the use of metformin in Phase B, no statistical comparisons of efficacy were made between the ertugliflozin and placebo/metformin groups at Week 52.. The mean (standard error) change from baseline to Week 52 in HbA1c was -0.9% (0.1) and -1.0% (0.1) in the ertugliflozin 5 and 15 mg groups, respectively. The proportions of participants with HbA1c <7.0% at Week 52 were 25.6% and 28.5%, respectively. Ertugliflozin reduced fasting plasma glucose, body weight and systolic blood pressure (SBP). The incidence of genital mycotic infections (GMIs) in females was significantly higher in both ertugliflozin groups (5 mg, 26.9%; 15 mg, 29.0%) vs the placebo/metformin group (9.9%), and in males was significantly higher in the 15 mg group (7.8%) vs the placebo/metformin group (1.2%). Ertugliflozin was not associated with increased incidence of urinary tract infections, symptomatic hypoglycaemia or hypovolaemia adverse events compared with placebo/metformin.. Ertugliflozin treatment over 52 weeks improved glycaemic control and reduced body weight and SBP, but increased GMIs.
