In a substudy of SUSTAIN 8 (n = 178), which was reported separately at the meeting, both semaglutide and canagliflozin reduced total fat mass as assessed with whole-body, dual-energy x-ray absorptiometry scanning. The changes in total fat mass from baseline to week 52 were a respective –3.4 kg and –2.6, or 1.4% and 1.2%. Total lean mass changed by a respective –2.3 kg and –1.5 kg (1.2% and 1.1%), and visceral fat mass by –0.2 kg and –0.1 kg (–0.9% and 0.4%). There was no statistical significance between the groups. A post hoc analysis did show, however, that a greater drop in waist circumference might be achieved with semaglutide than with canagliflozin (–4.0 vs. –2.9 cm [–3.9% vs. –2.5%], P = .02).
“Importantly, neither treatment was associated with deleterious body composition changes, such as gains in fat mass or reductions in the total lean mass,” said Rory McCrimmon, MBChB, professor of experimental diabetes and metabolism at the University of Dundee, Scotland, when presenting the substudy findings.
“These findings are consistent with results from other body composition studies with GLP-1 RAs and SGLT2 [inhibitors],”Dr. McCrimmon said, adding that “the positive effects on total fat loss and visceral fat reduction highlight the role of semaglutide and canagliflozin as relevant treatment options for patients with type 2 diabetes.”
Novo Nordisk funded the study. Dr. Lingvay has received consulting fees from Novo Nordisk; research grants from her institution; and grants, personal fees, or both, from other companies not related to the study. Dr. McCrimmon has received personal fees from Novo Nordisk and two other companies.
