Aims To evaluate pazopanib eye drops in patients with subfoveal choroidal neovascularisation secondary to age-related macular degeneration.
Methods 70 patients with minimally classic or occult subfoveal choroidal neovascularisation were randomly assigned to 5 mg/mL TID, 2 mg/mL TID, and 5 mg/mL QD pazopanib eye drops for 28 days in a multicentre, double-masked trial with an optional safety extension for up to 5 additional months. The primary outcomes were central retinal thickness (CRT) and best-corrected visual acuity (BCVA) at Day 29.
Results No significant decrease from baseline in CRT was observed overall; however, an exploratory analysis showed improvement in CRT (mean decrease of 89 μm) in patients with the CFH TT genotype who received 5 mg/mL TID (p=0.01, n=5). Mean increases in BCVA were observed in the 5 mg/mL TID overall (4.32 letters (p=0.002, n=26)) and in those that with CFH Y402H TT (6.96 letters (p=0.02, n=5)) and CT (4.09 letters (p=0.05, n=9)) genotypes. No safety signals that precluded continued investigation were detected.
Conclusions 5 mg/mL pazopanib eye drops resulted in mean improvement in BCVA at Day 29 and improvements in vision. However, improvement in macular oedema for age-related macular degeneration was found only in the subset of subjects with the CFH Y402H TT genotype, warranting further investigation.
