OBJECTIVE: To evaluate 2 different dosing regimens of intravitreal bevacizumab for the treatment of neovascular age-related macular degeneration (AMD) patients in China.
DESIGN: Multicenter, randomized, prospective, open-label clinical trial.
PARTICIPANTS: One hundred eighty-five patients with active neovascular AMD, exclusion of a macular scar, choroidal neovascularization not resulting from AMD, and polypoidal choroidal vasculopathy.
INTERVENTION: Patients were assigned randomly to receive intravitreal injections of bevacizumab every 6 weeks for the first 3 injections followed by injections every 6 weeks (regimen A, n = 91) or every 12 weeks (regimen B, n = 94).
MAIN OUTCOME MEASURES: The primary outcome measure was a comparison of the mean change in visual acuity from baseline. The secondary outcome measure was a comparison of the proportion of patients with a change in visual acuity of 15 letters or more. Adverse events were monitored.
RESULTS: One-hundred eighty five patients were enrolled. At 48 weeks, the increase in the mean visual acuity measurements from baseline were 12.58 letters in regimen A and 10.06 letters in regimen B (P = 0.288). At 48 weeks, the percentage of eyes losing fewer than 15 letters was 96.2% in regimen A and 93.9% in regimen B (P = 0.720). At 48 weeks, the median decrease in central retinal thickness measurements from baseline was 119 μm in regimen A and 60 μm in regimen B (P = 0.221). Adverse events during the 48 weeks included anterior chamber inflammation in 17 patients (18.7%) from regimen A and 9 patients (9.6%) from regimen B (P = 0.075). There were no other notable ocular adverse events in either group.
CONCLUSIONS: Intravitreal bevacizumab improved visual acuity and decreased macular thickness in patients with neovascular AMD when dosed either every 6 weeks or every 12 weeks after 3 doses given at 6-week intervals. Although there were no statistically significant differences between the 2 regimens, the results tended to favor the group dosed every 6 weeks (regimen A).
