AIMS
This program investigated topical regorafenib, a multikinase inhibitor, in patients with neovascular age-related macular degeneration (nAMD).
METHODS
Topical regorafenib was investigated in an open-label, phase IIa/b study in which patients with choroidal neovascularization (CNV) secondary to nAMD received regorafenib (25 μL, 30 mg/mL TID) for 12 weeks. The primary endpoint of the phase II/a/b study was mean change in best-corrected visual acuity (BCVA) from baseline to weeks 4 and 12.
RESULTS
In nAMD patients (N = 51), mean changes in BCVA were +1.2 (90% CI -0.61 to 2.97) and -2.4 (90% CI, -4.18 to -0.54) letters at weeks 4 and 12, respectively. Ocular treatment-emergent adverse events (TEAEs) (study eye) were reported in 21 patients by week 12. There was 1 serious ocular TEAE (visual acuity reduced) that was not drug related. Twenty patients required rescue (intravitreal ranibizumab).
CONCLUSIONS
The program was terminated after phase IIa ended because efficacy was less than with current nAMD treatments. According to elaborate post hoc analyses, the most likely reason was insufficient exposure in the target compartment (back of the eye).
