    Aim: To assess patient-reported outcomes (PROs) in the SoliMix trial, which compared the efficacy and safety of iGlarLixi versus BIAsp 30 in people with type 2 diabetes (T2D).

    Materials and Methods: SoliMix (EudraCT: 2017-003370-13), a 26-week, open-label study, randomized (1:1) 887 adults with T2D and HbA1c ≥7.5%-≤10.0% (≥58-≤86 mmol/mol) on basal insulin plus oral antihyperglycaemic drugs (OADs) to once-daily iGlarLixi or twice-daily premix insulin, BIAsp 30. PROs were assessed using the Treatment-Related Impact Measure Diabetes (TRIM-D) and Global Treatment Effectiveness Evaluation (GTEE) questionnaires.

    Results: Over 26 weeks, iGlarLixi showed greater improvement from baseline versus BIAsp 30 in total TRIM-D score (least squares mean difference [95% confidence interval]: 5.08 [3.69, 6.47]; effect size: 0.32) and in each TRIM-D domain, with the greatest differences seen in diabetes management (8.47 [6.11, 10.84]) and treatment burden (6.95 [4.83, 9.07]). GTEE scores showed a greater proportion of participants and physicians rated a complete or marked improvement of diabetes control with iGlarLixi (80.5%, 82.8%) versus BIAsp 30 (63.3%, 65.1%) at week 26. Post hoc analyses showed that after adjusting for HbA1c, body weight and hypoglycaemia outcomes, iGlarLixi continued to show greater improvements in TRIM-D total scores versus BIAsp 30.

    Conclusions: In addition to better glycaemic control, weight benefit and less hypoglycaemia, once-daily iGlarLixi provided improved diabetes management, treatment burden and perceived effectiveness versus twice-daily premix BIAsp 30, further supporting iGlarLixi as an advanced treatment option in people with suboptimally controlled T2D on basal insulin plus OADs.
