A Randomized, Open-Label Comparison of Once-Weekly Insulin Icodec Titration Strategies Versus Once-Daily Insulin Glargine U100.

ABSTRACT:

Objective

Insulin icodec is a novel once-weekly basal insulin analog. This trial investigated the efficacy and safety of icodec using different once-weekly titration algorithms.

Research design and methods

This was a phase 2, randomized, open-label, 16-week, treat-to-target study. Insulin-naive adults (n = 205) with type 2 diabetes and HbA_1c 7-10% while treated with oral glucose-lowering medications initiated once-weekly icodec titrations A (prebreakfast self-measured blood glucose target 80-130 mg/dL; adjustment ±21 units/week; n = 51), B (80-130 mg/dL; ±28 units/week; n = 51), or C (70-108 mg/dL; ±28 units/week; n = 52), or once-daily insulin glargine 100 units/mL (IGlar U100) (80-130 mg/dL; ±4 units/day; n = 51), all titrated weekly. Percentage of time in range (TIR) (70-180 mg/dL) during weeks 15 and 16 was measured using continuous glucose monitoring.

Results

TIR improved from baseline (means: A, 57.0%; B, 55.2%; C, 51.0%; IGlar U100, 55.3%) to weeks 15 and 16 (estimated mean: A, 76.6%; B, 83.0%; C, 80.9%; IGlar U100, 75.9%). TIR was greater for titration B than for IGlar U100 (estimated treatment difference 7.08%-points; 95% CI 2.12 to 12.04; P = 0.005). No unexpected safety signals were observed. Level 2 hypoglycemia (<54 mg/dL) was low in all groups (0.05, 0.15, 0.38, 0.00 events per patient-year of exposure for icodec titrations A, B, and C and IGlar U100, respectively), with no episodes of severe hypoglycemia.

Conclusions

Once-weekly icodec was efficacious and well tolerated across all three titration algorithms investigated. The results for icodec titration A (80-130 mg/dL; ±21 units/week) displayed the best balance between glycemic control and risk of hypoglycemia.

Project description:Insulin icodec* (icodec) is a novel once-weekly basal insulin analog in development. This post hoc analysis explored hypoglycemia duration using double-blinded CGM (Dexcom G6®) data from 2 phase 2, randomized, open-label, treat-to-target 16-week trials. One trial compared 3 titration algorithms of icodec vs. insulin glargine U100 (IGlar U100) in 205 insulin-naïve patients with T2D (NCT03951805), the other assessed 154 basal insulin-treated patients with T2D switching from any daily basal insulin to icodec with or without a 100% loading dose vs. IGlar U100 (NCT03922750). In line with ATTD guidelines, a hypoglycemic episode was defined as a CGM period of interstitial glucose (IG) <70 mg/dL for at least 15 min, ending when IG ≥70 mg/dL for at least 15 min. In the titration trial, hypoglycemia duration was similar across all arms: median overall hypoglycemic episode duration (IQR) was 35.0 (20.0, 70.0) min for icodec titrations A (SMBG 80-130 mg/dL ±21 U/wk) and B (80-130 mg/dL ±28 U/wk) and for IGlar U100 (80-130 mg/dL ±4 U/day), and 39.0 (24.0, 70.0) min for icodec titration C (70-108 mg/dL ±28 U/wk). The distribution pattern of hypoglycemic episodes by duration was similar across all treatment arms. Results were similar for nocturnal hypoglycemic episodes. Similarly, in the switch trial, the duration of hypoglycemia was similar between arms, irrespective of loading dose use: median overall hypoglycemic episode duration (IQR) was 40.0 (20.0, 75.0) min for icodec with loading dose, 40.0 (25.0, 80.0) min for icodec without loading dose, and 35.0 (20.0, 60.0) min for IGlar U100. The distribution pattern of hypoglycemic episodes by duration was similar across treatment arms. Similar results were seen for the nocturnal period. In conclusion, CGM-derived hypoglycemic episode duration was similar with icodec vs. IGlar U100 in insulin-naïve and insulin-experienced patients with T2D, regardless of titration algorithm or initial loading dose use. *Proposed INN.

Project description:ImportanceOnce-weekly insulin icodec could provide a simpler dosing alternative to daily basal insulin in people with type 2 diabetes.ObjectiveTo evaluate the efficacy and safety of once-weekly icodec vs once-daily insulin degludec in people with insulin-naive type 2 diabetes.Design, setting, and participantsRandomized, double-masked, noninferiority, treat-to-target, phase 3a trial conducted from March 2021 to June 2022 at 92 sites in 11 countries in adults with type 2 diabetes treated with any noninsulin glucose-lowering agents with hemoglobin A1c (HbA1c) of 7%-11% (53-97 mmol/mol).InterventionsParticipants were randomly assigned in a 1:1 ratio to receive either once-weekly icodec and once-daily placebo (icodec group; n = 294) or once-daily degludec and once-weekly placebo (degludec group; n = 294).Main outcomes and measuresThe primary end point was change in HbA1c from baseline to week 26 (noninferiority margin, 0.3% percentage points). Secondary end points included change in fasting plasma glucose from baseline to week 26, mean weekly insulin dose during the last 2 weeks of treatment, body weight change from baseline to week 26, and number of level 2 (clinically significant; glucose level <54 mg/dL) and level 3 (severe; requiring external assistance for recovery) hypoglycemic episodes.ResultsAmong 588 randomized participants (mean [SD] age, 58 [10] years; 219 [37%] women), 564 (96%) completed the trial. Mean HbA1c level decreased from 8.6% (observed) to 7.0% (estimated) at 26 weeks in the icodec group and from 8.5% (observed) to 7.2% (estimated) in the degludec group (estimated treatment difference [ETD], -0.2 [95% CI, -0.3 to -0.1] percentage points), confirming noninferiority (P < .001) and superiority (P = .002). There were no significant differences between the icodec and degludec groups for fasting plasma glucose change from baseline to week 26 (ETD, 0 [95% CI, -6 to 5] mg/dL; P = .90), mean weekly insulin dose during the last 2 weeks of treatment, or body weight change from baseline to week 26 (2.8 kg vs 2.3 kg; ETD, 0.46 [95% CI, -0.19 to 1.10] kg; P = .17). Combined level 2 or 3 hypoglycemia rates were numerically higher in the icodec group than the degludec group from week 0 to 31 (0.31 vs 0.15 events per patient-year exposure; P = .11) and statistically higher in the icodec group from week 0 to 26 (0.35 vs 0.12 events per patient-year exposure; P = .01).Conclusions and relevanceAmong people with insulin-naive type 2 diabetes, once-weekly icodec demonstrated superior HbA1c reduction to once-daily degludec after 26 weeks of treatment, with no difference in weight change and a higher rate of combined level 2 or 3 hypoglycemic events in the context of less than 1 event per patient-year exposure in both groups.Trial registrationClinicalTrials.gov Identifier: NCT04795531.
