Effects of switching to a titratable fixed-ratio combination of insulin glargine plus lixisenatide (iGlarLixi) in patients (pts) with T2D on GLP-1 RAs have been unknown. LixiLan-G (NCT02787551), a randomized, open-label, 26-week trial, compared switching to iGlarLixi vs. continued GLP-1 RA use in pts with T2D and HbA1c 7-9% despite receiving a maximum tolerated dose of a GLP-1 RA (liraglutide QD, exenatide BID, exenatide extended-release QW, albiglutide QW, or dulaglutide QW) with metformin ± pioglitazone ± SGLT2i. Treatment effects seen across baseline factors, such as BMI, GLP-1 RA type, and pioglitazone or SGLT2i use, were consistent with the primary analysis. This exploratory analysis examined HbA1c change at week 26 and documented symptomatic hypoglycemia in 26-week completers (modified ITT) by screening subgroup HbA1c levels (≤7.5%, &gt;7.5-≤8%, and &gt;8%). At week 26, mean HbA1c levels for iGlarLixi were 6.6%, 6.6%, and 6.9%, respectively, vs. 7.2%, 7.4%, and 7.5%, respectively, for GLP-1 RAs. Reductions were greater for iGlarLixi than for GLP-1 RAs in all subgroups (p&lt;0.0001; Figure). Symptomatic hypoglycemia rates were low overall but higher with iGlarLixi than with GLP-1 RAs (Figure).
In conclusion, in pts with T2D inadequately controlled on GLP-1 RA and OAD(s), iGlarLixi demonstrated additional glycemic benefit across a broad range of HbA1c levels.
