Ranibizumab combined with low-dose sorafenib for exudative age-related macular degeneration.
Angiogenesis is a common factor in the pathogenesis of cancer and in exudative age-related macular degeneration (AMD). Therefore, angiogenesis inhibition has been developed as a therapeutic strategy. We report 2 cases of recurrent exudative AMD in which oral sorafenib, a tyrosine kinase inhibitor approved for cancer, was added to intravitreal ranibizumab, an antibody to vascular endothelial growth factor. These 2 patients were followed up by determination of visual acuity, fluorescein angiography, fundoscopy, and optical coherence tomography. The visual acuity of 1 patient improved from 20/70 to 20/60 while he was receiving sorafenib therapy; that of the other did not. Marked improvement was noted in both patients on optical coherence tomography. Additionally, both patients appeared to receive some benefit when low-dose oral sorafenib was used as monotherapy after its initial addition to ranibizumab therapy. Randomized trials of adding sorafenib to standard therapy for patients with neovascular AMD should be considered.
