Abstract

AIMS:

To explore the effects of dual therapy with dapagliflozin and exenatide on body weight, body composition, glycaemic variables and systolic blood pressure (SBP) in obese adults without diabetes.

MATERIALS AND METHODS:

In this single-centre, double-blind trial, we randomized 50 obese adults without diabetes (aged 18-70 years; body mass index 30-45 kg/m2 ) to oral dapagliflozin 10 mg once daily plus subcutaneous long-acting exenatide 2 mg once weekly or placebo. MRI was used to assess change in body composition. Participants were instructed to follow a balanced diet and exercise moderately.

RESULTS:

Of 25 dapagliflozin/exenatide- and 25 placebo-treated participants, 23 (92.0%) and 20 (80.0%) completed 24 weeks of treatment, respectively. At baseline, the mean participant age was 52 years, 61% were female, the mean body weight was 104.6 kg, and 73.5% of participants had prediabetes (impaired fasting glucose or impaired glucose tolerance). After 24 weeks, for dapagliflozin/exenatide versus placebo: the difference in body weight change was -4.13 kg (95% confidence interval -6.44, -1.81; P < .001), which was mostly attributable to adipose tissue reduction without lean tissue change; 36.0% versus 4.2% of participants achieved ≥5% body weight loss, respectively; and prediabetes was less frequent with active treatment (34.8% vs 85.0%, respectively; P < .01). The difference in SBP change for dapagliflozin/exenatide versus placebo was -6.7 mm Hg. As expected, nausea and injection-site reactions were more frequent with dapagliflozin/exenatide than with placebo. Only two and three participants, respectively, discontinued because of adverse events.

CONCLUSIONS:

Compared with placebo, dapagliflozin/exenatide dual therapy reduced body weight, frequency of prediabetes and SBP over 24 weeks and was well tolerated in obese adults without diabetes.
