Abstract
Purpose :
To evaluate the efficacy and safety of RBZ in patients with visual impairment due to CNV other than neovascular age-related macular degeneration and myopic CNV. The 6-month (M) results are reported here.
Methods :
MINERVA is a 12M, phase III, randomized, double-masked, sham-controlled, multicenter study including adult (≥18 years) and adolescent (≥12–<18 years) patients. Adult patients (N=178) were randomized (2:1) to receive RBZ (n=119) or sham (n=59) at baseline (BSL) and then treated as needed. From M2, adult patients in both groups could receive open-label RBZ as needed. The primary endpoint was change in best-corrected visual acuity (BCVA) from BSL to M2. Secondary outcomes included changes from BSL in BCVA to M1/M2 and central subfield thickness (CSFT) to M2, absence of intra-/sub-retinal fluid at M2, ≥10/≥15 letter gainers at M2, treatment exposure, and safety up to M6. Secondary efficacy endpoints are presented for patients initially assigned to RBZ and sham. Moreover, a subgroup analysis was conducted on the primary endpoint based on 5 pre-defined CNV etiology subgroups.
Results :
Data have been analyzed for adults up to M6 and presented here. Of the 178 randomized patients, 174 (97.8%) completed M6. The baseline characteristics were well balanced across the 2 arms. The primary endpoint was met with RBZ showing superior efficacy vs sham from BSL to M2 (adjusted least-squares [LS] mean BCVA: +9.5 letters vs −0.4 letters; one-sided p<0.001). Across the 5 CNV etiology subgroups, the treatment effect (adjusted LS means) ranged from 5.02–14.57 letters (Fig. 1). At M6, change in BCVA (Fig. 2) was +10.3 letters (RBZ) vs +7.5 letters (sham). Adjusted LS mean change in CSFT from BSL to M2 was −77.0 µm (RBZ) vs +9.8 µm (sham); one-sided p<0.001. At M2, intra-/sub-retinal fluid resolved in 67.4%/56.0% (RBZ) vs 29.2%/14.0% (sham) of patients. The proportion of patients with ≥10/≥15 letter gain at M2 was 42.4%/31.4% (RBZ) vs 14.0%/12.3% (sham). Out of a possible 6 (RBZ) and 4 (sham) RBZ injections, patients received a mean of 3.7 (RBZ) vs 2.7 (sham) RBZ injections. No new safety findings were reported up to M6.
Conclusions :
Ranibizumab showed significant gain of ~10 letters at M2 that was maintained at M6. RBZ is effective for the treatment of CNV regardless of the underlying etiology with no new safety concerns.
