a study on Central Retinal Vein Occlusion
SCORE2 is a multicenter, prospective, randomized, phase III clinical trial in which all participants enrolled will be followed for up to 2.5 years. SCORE2 is designed as a non-inferiority trial, with study eyes randomized to intravitreal bevacizumab (1.25 mg) every 4 weeks vs. intravitreal aflibercept (2.0 mg) every 4 weeks. SCORE2 aims to determine if bevacizumab is non-inferior to aflibercept for the treatment of macular edema associated with central retinal vein occlusion (CRVO), with the primary outcome of visual acuity measured at Month 6.
Study of COmparative Treatments for REtinal Vein Occlusion 2 [SCORE2]: a Multicenter, Prospective, Randomized Non-inferiority Trial of Eyes With Macular Edema Secondary to Central Retinal Vein Occlusion, Comparing Intravitreal Bevacizumab Every 4 Weeks With Intravitreal Aflibercept Every 4 Weeks.
The primary objective of SCORE2 is to test for non-inferiority based on mean change from baseline in visual acuity letter score at Month 6 for eyes randomized to intravitreal bevacizumab every 4 weeks compared with eyes randomized to intravitreal aflibercept every 4 weeks using a non-inferiority margin of 5 letters.
Secondary objectives of SCORE2 are to:
Other exploratory aims of SCORE2 are to:
Central Retinal Vein Occlusion Bevacizumab
Open to people ages 18 years and up
CRVO used in SCORE will also be used for the purposes of SCORE2: a CRVO is defined as an eye that has retinal hemorrhage or other biomicroscopic evidence of retinal vein occlusion (e.g., telangiectatic capillary bed) and a dilated venous system (or previously dilated venous system) in all 4 quadrants.
