Abstract

Objective: This retrospective database analysis complements previous research to understand treatment patterns for German patients newly-initiating or switching to subsequent GLP-1 RAs.

Methods: Adult patients (≥18 years) initiating GLP-1 RA (Cohort 1 [C1]) or switching from a previous GLP-1 RA (Cohort 2 [C2]) to exenatide twice-daily (exBID), exenatide once-weekly (exQW), dulaglutide (DULA), or liraglutide (LIRA) were included in this analysis using IQVIA LRx from January 1, 2014March 31, 2017. Patients were required to have ≥1 oral anti-hyperglycemic prescription during the 6-month pre-index period and ≥12 months follow-up. Persistence and treatment modifications were assessed within and beyond 12 months follow-up. Average daily/weekly dosage (ADD/AWD) was calculated during persistence.

Results: C1 included 13,417 patients, while C2 included 4,264 patients. Mean ± standard deviation (SD) age was similar (57.7 ± 11.1 years [C1], 58.9 ± 10.1 years [C2]). Most patients using DULA in C2 had switched from LIRA (56.6%). For C1, mean ADD for LIRA was 1.41 ± 0.10 mg, slightly higher in C2, and increased over time. ADD for exBID was 16.9 ± 1.0 mcg, slightly greater in C2. AWD was 2.00 ± 0.05 mg for exQW users and 1.42 ± 0.03 mg for DULA users in C1, similar to C2. For C1, 27.0% exBID, 35.3% exQW, 50.9% DULA, and 48.1% LIRA users remained persistent at 12 months. Patients using DULA had a higher probability of remaining persistent over time (Kaplan-Meier) for both cohorts.

Conclusions: Patients using DULA had the highest probability of remaining persistent over time, followed by LIRA. ADD/AWD for DULA, exQW, and exBID were aligned with the recommended combination therapy dose; LIRA ADD suggests some patients use the 1.8 mg dose.
