Abstract

OBJECTIVE: The principle of replacing prandial insulin lispro with a once-weekly glucagon-like peptide 1 receptor agonist (GLP-1RA) for type 2 diabetes inadequately controlled on a multiple daily insulin injections regimen was tested with albiglutide. RESEARCH DESIGN AND METHODS: In this treat-to-target study, basal plus prandial insulin was optimized over 4 weeks before participants were randomized (1:1) to albiglutide plus optimized basal insulin glargine and lispro (dose reduced by 50% at randomization; subsequently, lispro injections were fully discontinued 4 weeks later) (n = 402) or to continued optimized lispro plus optimized glargine (n = 412). RESULTS: Mean ± SD HbA1c at baseline, 7.8 ± 0.6% (61 ± 7 mmol/mol) in the albiglutide + glargine group and 7.7 ± 0.6% (60 ± 7 mmol/mol) in the lispro + glargine group, was reduced at week 26 to 6.7 ± 0.8% (49 ± 8 mmol/mol) and 6.6 ± 0.8% (48 ± 8 mmol/mol), respectively (least squares [LS] difference 0.06% [95% CI −0.05 to 0.17]; noninferiority P < 0.0001). In the albiglutide + glargine group, 218 participants (54%) replaced all prandial insulin without reintroducing lispro up to week 26. Total daily prandial insulin dose was similar at baseline but was lower by 62 units/day (95% CI −65.9 to −57.8; P < 0.0001) at week 26 in the albiglutide + glargine group, and the total number of weekly injections was also reduced from 29 to 13 per week. Less severe/documented symptomatic hypoglycemia (57.2% vs. 75.0%) occurred in the albiglutide + glargine group with meaningful weight differences (LS mean ± SE −2.0 ± 0.2 vs. +2.4 ± 0.2 kg; P < 0.0001) vs. lispro + glargine. Gastrointestinal adverse events were higher with albiglutide + glargine (26% vs. 13%). CONCLUSIONS: A once-weekly GLP-1RA was able to substitute for prandial insulin in 54% of people, substantially reducing the number of prandial insulin injections; glycemic control improved, with the added benefits of weight loss and less hypoglycemia in the GLP-1RA arm. Replacing prandial insulin with a weekly GLP-1RA can simplify basal plus prandial insulin treatments and achieve better outcomes in type 2 diabetes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
