Safety of intravitreal ocriplasmin for focal vitreomacular adhesion in patients with exudative age-related macular degeneration.

The evaluation of the safety and preliminary efficacy of 125 μg ocriplasmin intravitreal injection in patients with focal vitreomacular adhesion (VMA) and exudative age-related macular degeneration (AMD). Randomized, sham-injection controlled, double-masked, multicenter, phase II trial. A total of 100 patients with VMA and wet AMD were randomized 3:1 to receive 125 μg ocriplasmin intravitreal injection or sham injection. Study treatment was administered in the mid-vitreous cavity by injection. Post-treatment safety and efficacy assessments were made at baseline and on days 7, 14, and 28 and months 3, 6, and 12 after injection. Secondary efficacy end points were exploratory in nature. The safety and tolerability of ocriplasmin were evaluated. The primary efficacy end point was the proportion of patients with VMA release at day 28 after injection. Secondary end points reported included VMA release over time, total posterior vitreous detachment (PVD), change in visual acuity from baseline, and number of anti-vascular endothelial growth factor (VEGF) injections. The safety of ocriplasmin in patients with VMA and wet AMD was shown to be comparable to the known safety profile, with the majority of adverse events in the study eye occurring in the first 7 days after study treatment. A greater proportion of patients achieved VMA resolution and total PVD at month 12 with ocriplasmin compared with sham treatment. There was a decrease in the number of anti-VEGF injections with ocriplasmin at month 12 compared with the sham group, although no differences in visual acuity were observed. Ocriplasmin treatment in this population seems to be generally safe and well tolerated and resulted in more patients achieving VMA resolution and PVD with less anti-VEGF use compared with sham treatment.
