To estimate the relative treatment effect of iGlarLixi (a fixed‐ratio combination of insulin glargine 100 U/mL plus lixisenatide) versus premixed insulin IDegAsp (insulin degludec plus insulin aspart) in people with type 2 diabetes (T2D) who advanced from basal insulin to iGlarLixi or IDegAsp in non‐Asian studies. The gene discussed is INS; the disease is type 2 diabetes mellitus.
