In people with type 2 diabetes uncontrolled by GLP-1 RAs, fixed-ratio combination (FRC; basal insulin + GLP-1 RA) is a recommended option. A PICO-framework systematic review of RCTs followed by an ITC was performed to compare the efficacy and safety of the FRCs iGlarLixi (insulin glargine 100 U/mL + lixisenatide) and IDegLira (insulin degludec + liraglutide) in this population. A fixed effects model was used on the two eligible RCTs. Outcomes: change from baseline to week 26 in HbA1c, clinic fasting plasma glucose (FPG), self-monitored plasma glucose (SMPG), and body weight; proportion achieving HbA1c <6.5 or <7.0 %; hypoglycemia incidence. Baseline characteristics were similar across studies. Significant mean differences were seen in change in HbA1c and FPG favoring IDegLira, but not pre- or postprandial SMPG (breakfast or daily average) or weight (Table). Similar proportions achieved HbA1c targets. Hypoglycemia comparisons suffered from varying definitions, sulfonylurea (SU) use and eligibility, and few events in the GLP-1 RA arms (incidence: 32% [confirmed ≤3.1 mmol/L, 28% without SU] with IDegLira and 9% or 28% [symptomatic <3.0 or ≤3.9 mmol/L] with iGlarLixi). This ITC shows similar FRC HbA1c glycemic target achievement but suggests divergent differences in other glycemia results and hypoglycemia, likely due to different study design and titration application.
