Sumario: | BACKGROUND: Administrative-claims data enable comparative effectiveness assessment using large numbers of patients treated in real-world settings. OBJECTIVE: To evaluate real-world relapses, healthcare costs and resource use in patients with MS newly initiating subcutaneous interferon beta-1a (sc IFNβ-1a) v. oral disease-modifying drugs (DMDs: dimethyl fumarate, fingolimod, teriflunomide). METHODS: Patients from an administrative claims database (1 Jan 2012–31 Dec 2015) were selected if they: were 18–63 years old; had an MS diagnosis; had newly initiated sc IFNβ-1a, dimethyl fumarate, fingolimod, or teriflunomide (first claim = index); had no evidence of DMD 12-months pre-index; and had 12-month eligibility pre- and post-index. Relapse was defined as an MS-related inpatient stay, emergency room visit, or outpatient visit with a corticosteroid prescription ± 7 days. Outcomes were evaluated using logistic regression and generalized linear models. RESULTS: A total of 4475 patients met inclusion criteria: 21.9% sc IFNβ-1a, 51.0% dimethyl fumarate, 19.7% fingolimod, 7.4% teriflunomide. Teriflunomide patients had 1.357 (95% CI 1.000, 1.831; p = 0.0477) greater odds of 1-year relapse than sc IFNβ-1a patients. Estimated mean all-cause 1-year costs were higher after fingolimod (US$72,376) v. sc IFNβ-1a initiation (US$65,408; p < 0.0001). Non-DMD costs were not significantly different. CONCLUSION: Patients initiating sc IFNβ-1a had better relapse outcomes v. teriflunomide, and lower all-cause costs v. fingolimod. |
