Summary

ObjectiveUsing national claims databases, we sought to emulate the design of the ongoing SEPRA trial and predict its findings, comparing the effects of once weekly semaglutide to SoC medications on glycemic control (A1C <7%) in type-2 diabetes mellitus (T2D).Research design and methodsUsing Optum Clinformatics (July 2017 - May 2022), we identified a 1:1 propensity score-matched (PSM) cohort of adults with T2D on metformin monotherapy, who had recorded A1C and initiated either injectable semaglutide or SoC medications (dipeptidyl peptidase-4 inhibitors, sodium-glucose cotransporter-2 inhibitors, SUs, or glucagon-like peptide-1 agonists) and met eligibility criteria adapted from the SEPRA trial. The primary outcome was the proportion of patients achieving A1C <7%. The study protocol was preregistered (NCT05577728, ClinicalTrials.gov) before any etiologic analyses. Risk ratios and corresponding 95% CIs were estimated.ResultsWe identified 1,144 PSM pairs of injectable semaglutide and SoC initiators with balance in pre-exposure covariates. Semaglutide initiators were 30% (risk ratio (95% CI), 1.30 (1.16 to 1.45)) more likely to achieve glycemic control (A1C <7%) than those initiating SoC. Additionally, semaglutide initiators had a 1.3% reduction in A1C, compared with a 1.1% reduction in the SoC group. These results were consistent with interim results of the SEPRA trial, which were released after the protocol for our database study was preregistered.ConclusionThis claims database study, designed to predict the results of the SEPRA trial, found results consistent with interim trial results. Our findings support the notion that well-designed non-randomized studies using fit-for-purpose data can effectively complement pragmatic randomized controlled trials.
