Ease of Use of the iGlarLixi SoloStar Pen from the LixiLan ONE CAN Pen Sub-Study: Questionnaire Findings from People Living with Type 2 Diabetes and Their HealthCare Providers.

Introduction: For people with type 2 diabetes mellitus who do not achieve glycated hemoglobin A1C targets after treatment with basal insulin therapies, additional therapy with a glucagon-like peptide-1 receptor agonist (GLP-1 RA) may be required. One option is to use a once-daily fixed-ratio combination (FRC) of basal insulin and a GLP-1 RA such as iGlarLixi (which is composed of insulin glargine 100 U/ml and lixisenatide). However, the ease of transitioning from basal insulin to an FRC has not been studied.

Methods: This sub-study of the LixiLan ONE CAN trial (NCT03767543) was conducted to assess the ease of transitioning from insulin glargine 100 U/ml to the FRC, iGlarLixi, using the iGlarLixi SoloStar pen. Patients completed a validated, ten-item questionnaire, and healthcare professionals (HCPs) completed a five-item questionnaire. Both questionnaires used either five-point Likert scales or yes/no answers as appropriate, and both were completed after 4 weeks of using the iGlarLixi SoloStar pen.

Results: Overall, 95.1% of patients reported that the iGlarLixi Solostar pen was "easy" or "very easy" to use. Similarly, 100% of HCPs reported that it was "easy" or "very easy" to train people to use the pen. Nearly all participants (97.5% of patients and 94% of HCPs) responded that they would recommend the iGlarLixi Solostar pen to others.

Conclusions: These results suggest that during the transition from insulin glargine 100 U/ml to iGlarLixi, there were no difficulties associated with using the iGlarLixi SoloStar pen injector regarding instruction for use by HCPs or actual use by the majority of patients. The results indicate a broad consensus between patients and HCPs on the relative simplicity of transitioning from self-administration of insulin glargine 100 U/ml to iGlarLixi.
