Abstract
Purpose: Vascular endothelial growth factor (VEGF) inhibition is the current and high-volume standard-of-care for patients with neovascular age-related macular degeneration (nAMD) and diabetic retinopathy (DR) with diabetic macular edema (DME). This study assessed the impact of non-persistence in anti-VEGF treatment using claims data from two German states.
Methods: This study identified adults with nAMD or DR/DME and incident anti-VEGF treatment (= index) in January 2015-June 2019 using the German AOK PLUS claims database (January 2014-June 2021, ~ 3.5 million insured). Baseline characteristics were observed within 12 months before index. Patient follow-up lasted ≥ 24 months or until death. Non-persistence (gap of ≥ 180 days) was calculated using Kaplan-Meier estimation. Cox regression identified variables linked to non- persistence. The study analysed reimbursed anti-VEGF treatments, thus excluding off-label use of bevacizumab.
Results: 5,498 patients diagnosed with nAMD (mean age, 80.09 years; male, 37.50%; mean Charlson Comorbidity Index [CCI] score, 3.07) and 484 patients with DR/DME (mean age, 67.14; male, 58.88%; mean CCI score, 4.54) were identified. Non-persistence to anti-VEGF treatment within 12 months after index occurred in 51.38% of nAMD patients and 62.60% of DR/DME patients, with mean times to first gap of 11.28 and 8.98 months, respectively. Cox regression revealed factors associated with non-persistence, including higher age, female gender, higher care needs, longer AMD history, and the use of ranibizumab.
Conclusion: Epidemiologic and ophthalmologic factors associated with anti-VEGF non-persistence were successfully identified in the first year of therapy. The analyzed dataset can potentially be enriched with additional health insurance database sets under the used criteria to gain more understanding of anti-VEGF non-persistence.
