PURPOSE: Injectable once weekly semaglutide for diabetes (OW sema) is a medication approved in 2017 for the treatment of patients with type 2 diabetes (T2DM). In clinical trials, OW sema has been shown to be effective at helping patients achieve glycemic targets. However, more data are needed to understand how patients who initiate treatment with OW sema are treated in the real world and to aid prescribers in making treatment decisions. This study characterized noninsulin antidiabetic medication use patterns among US patients with T2DM initiating treatment with OW sema.
METHODS: In this retrospective, claims-based study, patients (15,588) were included if they had at least 1 claim for OW sema between January 1, 2018 and December 31, 2019, were at least 18 years old, were continuously enrolled in the health plan, and had at least 1 claim indicating a diagnosis of T2DM. All patients had at least 1 line of therapy (LOT) that started on the date of the first fill for OW sema. Data related to pre-index date demographics and clinical characteristics were collected, as were data on patient regimens and LOTs. The length of the LOT was calculated, and the top 10 noninsulin treatment regimens were reported in each LOT.
FINDINGS: In the first LOT, OW sema monotherapy was the most common regimen. More than one third (36.5%) of patients had 1 LOT until the end of follow-up and most patients who had a second (52.1%) or third (72.0%) LOT continued it to the end of the study. Among the top 10 regimens, 42.2% of patients with a second LOT and 45.8% of patients with a third LOT had an LOT that included OW sema.
IMPLICATIONS: This study describes medication regimens within the first year of OW sema use. Among patients initiating OW sema, monotherapy was the most common regimen. These results provide insight into real-world usage patterns of this medication.
