A retrospective, observational analysis of administrative claims data from the IBM MarketScan Databases assessed adherence and persistence among GLP-1 RA naive adult patients with T2D newly initiating dulaglutide (DU) or oral semaglutide (OS) between Sept 2019 and Nov 2020.
Patients had continuous enrollment in the 6-mo pre-index period and 6-mo follow-up periods. The DU patients were propensity-score matched 1:1 to OS patients (6,166 pairs) . The median age was 54 years at index date, and 48% were female. At pre-index, mean aDCSI was 0.6 and 10% of patients had ASCVD. Most patients used oral anti-hyperglycemic medication (87%) ; a smaller proportion used insulin (15%) . The most common prescribing provider was primary care (62%) .
More DU patients were adherent (proportion days covered [PDC] ≥80%) (65% vs. 50%, p<0.001) and had higher mean PDC vs. OS (0.78 vs. 0.68, p<0.001) . More DU patients were persistent on therapy compared to OS patients (72% vs. 57% p<0.001) and had longer mean duration of persistence (148 vs. 128, p<0.001) . Among patients with ≥2 fills of their index drug, 73% of DU and 62% of OS patients were adherent.
During the 6-mo follow-up period, DU patients had significantly higher adherence and persistence compared to OS patients.
