Cost-Minimization Analysis of Ranibizumab Versus Aflibercept for Treating Saudi Patients With Visual Impairment Owing to Age-Related Macular Degeneration or Diabetic Macular Edema.

The standard-of-care treatment for age-related macular degeneration (AMD) and diabetic macular edema (DME) includes inhibiting blood vessel proliferation and reducing macular edema or swelling using anti–vascular endothelial growth factor therapies, such as ranibizumab and aflibercept. To conduct a cost-minimization analysis of ranibizumab and aflibercept for treating Saudi patients with visual impairment owing to AMD or DME. Cost minimization was analyzed assuming that ranibizumab and aflibercept have equivalent clinical effectiveness. The third-party payer's perspective was used in several clinical scenarios. The base-case scenario was DME cases followed monthly using a protocol-specific follow-up. In scenario 1, AMD cases followed a treat-and-extend protocol over 2 years. In scenario 2, AMD cases followed the PRN (pro re nata) regimen over 2 years. In scenario 3, DME cases followed the PRN regimen for 1 year only. Aflibercept yielded cost savings of 25.75%, 31.54%, 51.30%, and 9.28% compared with ranibizumab for the base case, scenario 1, scenario 2, and scenario 3, respectively, which supports the premise that aflibercept is more cost saving than ranibizumab. From the third-party payer perspective, aflibercept is a cost-containment option that provides substantial savings over ranibizumab for treating Saudi patients with AMD or DME. [ABSTRACT FROM AUTHOR]
