Background: InRange has previously demonstrated that insulin glargine 300 U/mL (Gla-300) is non-inferior to insulin degludec 100 U/mL (IDeg-100) in terms of time in glucose range 70--180 mg/dL (primary endpoint) and total glucose coefficient of variation (CV) as measured by CGM in people with T1D.

Methods: InRange (NCT04075513) was a multicenter, randomized, active-controlled, parallel-group, 12-week open-label trial comparing Gla-300 vs. IDeg-100 in adults with T1D using 20-day CGM profiles (≥10 days evaluable) . Here we present data for within- and between-day CV.

Results: Overall, 343 participants were randomized (172 Gla-300, 171 IDeg-100) : mean ± SD age was 42.8 ± 13.3 years and T1D duration was 20.5 ± 12.8 years. Both within-day and between-day glucose CV at Week 12 were similar with Gla-300 and IDeg-100 (Table) . Within-day glucose CV at Week 12 was below the threshold for glycemic stability (36%) in both groups and was also similar in both treatment groups irrespective of glycemic stability at baseline (CV ≤36% or >36%) . The LS mean within-day glucose CV of participants with CV >36% at baseline reached 33.67 (Gla-300) and 35.38 (IDeg-100) at Week 12.

Conclusion: Using clinically relevant CGM metrics, InRange shows that Gla-300 and IDeg-100 provide similar within- and between-day glucose variability in people with T1D.
