Abstract

Introduction: The treatment landscape for type 2 diabetes mellitus (T2DM) is complex and constantly evolving, and real-world evidence of prescribing patterns is limited. The objectives of this study were to characterize lines of therapy (LOTs), calculate the length of time spent on each LOT, and identify the reasons for the LOT end among patients who initiated oral semaglutide for T2DM.

Methods: This retrospective, claims-based study included commercial and Medicare Advantage adults with T2DM. Data from November 1, 2019, and June 30, 2020, were obtained from Optum Research Database. Patients with ≥ 1 claim for oral semaglutide and continuous health plan enrollment for ≥ 12 months prior to (baseline period) and ≥ 6 months following (follow-up period) the date of the first oral semaglutide claim were included. LOT 1 began on the date of the first oral semaglutide claim. The start date of any subsequent LOTs was the date of the first claim for an additional non-insulin anti-diabetic drug class or a reduction in drug class with use of commitment medications. The LOT ended at the first instance of medication class discontinuation, change in regimen or end of follow-up.

Results: Of the 1937 patients who initiated oral semaglutide, 950 (49.0%) remained on their initial regimen over the 6-month follow-up period, 844 (43.6%) had at least one subsequent LOT, and 89 (4.6%) had at least two subsequent LOTs. Among patients with more than one LOT, approximately 20%-25% used oral semaglutide as monotherapy or combination therapy during LOTs 2 and 3. Metformin was frequently used during treatment across all LOTs.

Conclusion: This study provides insight for physicians and payers into the real-world prescribing practices within the first 6 months following oral semaglutide initiation and fills the gap in understanding the frequency of regimen changes in the constantly evolving and complex environment of T2DM care.

Plain language summary

Type 2 diabetes mellitus is a disease which, over time, can cause higher than normal levels of sugar in the blood (hyperglycemia) which can be harmful if not treated. Treatment for type 2 diabetes mellitus can be complex, and how doctors prescribe medications is always changing. For some people with type 2 diabetes mellitus who are overweight or obese, it is recommended for patients to use certain medications that can help with weight management such as semaglutide and metformin. This study aims to fill gaps in current treatment knowledge about type 2 diabetes mellitus patients and their treatment of oral semaglutide. Researchers in this study explored how patients treated with oral semaglutide differentiated among line of therapies, how long patients stuck to them and why they stopped. The study found that those patients who started with oral semaglutide, almost half of those patients stuck to their initial treatment plan for the entire 6 months. When it came to the top ten treatment plans, about 20% of patients used oral semaglutide alone and about 25% of patients used oral semaglutide plus an additional treatment option. Metformin was frequently used during treatment across all line of therapies. There is little information on the real-life setting of treatment after the start of therapy for type 2 diabetes mellitus. The results from this study show what happens when patients start using oral semaglutide and helps healthcare providers understand how often treatment plans can change in type 2 diabetes mellitus care.
