LixiLan-G (NCT02787551) was a randomized, open-label, 26-week trial in T2D participants (pts) with HbA1c 7‒9%, receiving maximum tolerated doses of a once- or twice-daily (QD/BID) GLP-1 RA or a once-weekly (QW) GLP-1 RA with metformin ± pioglitazone ± SGLT2i. Pts were randomized to continue their GLP-1 RA regimen with supported adherence or switch to a fixed-ratio combination of insulin glargine and lixisenatide (iGlarLixi). This exploratory analysis assessed efficacy and safety by daily or weekly GLP-1 RA use at screening. Among 514 randomized pts, 60% and 40% were on daily and weekly GLP-1 RA, respectively, at screening (liraglutide QD 54%, dulaglutide QW 20%, exenatide extended-release QW 18%, exenatide BID 5%, albiglutide QW 2% [all % rounded]); GLP-1 RA treatment and T2D duration were slightly longer in the QD/BID vs. QW subgroup (Table). Change in HbA1c was larger with iGlarLixi vs. GLP-1 RA regardless of GLP-1 RA subtype (LS mean difference: −0.7 [95% confidence interval (CI): −0.8, −0.5] with QD/BID formulations, −0.6 [95% CI: −0.8, −0.4] with QW formulations). Similar results were observed for FPG and 2-hour PPG (Table). Safety profiles of iGlarLixi and GLP-1 RA were consistent with previous publications.
In conclusion, benefits of switching to iGlarLixi vs. continued GLP-1 RA in inadequately controlled T2D are observed irrespective of daily or weekly GLP-1 RA use.
