Across the GATHER clinical trials, IZERVAY reduced GA growth:
*As early as 6 months2
Across all prespecified patient subgroups¶
Trial Design: The safety and efficacy of IZERVAY were demonstrated in GATHER1 and GATHER2: 2 randomized, multi-center, double-masked sham-controlled studies in patients with age related macular degeneration (AMD). 292 patients were treated with IZERVAY 2 mg, and 332 patients received sham. The primary efficacy endpoint in both pivotal studies was the mean rate of GA growth (slope) from baseline to Month 12 over 3 timepoints: Baseline, Month 6, Month 12. In each study, over a 12-month period, there was a statistically significant reduction of the rate of GA growth (0.10 mm/year; p<0.01 in GATHER1 and 0.05 mm/year; p<0.01 in GATHER2 with square root transformed data) in patients treated with IZERVAY compared to sham.
IZERVAY post hoc analysis signaled reduction in risk of vision loss compared to sham11
Persistent vision loss in this pooled analysis was defined as a loss of ≥15 letters (ETDRS) in BCVA from baseline measured at any 2 consecutive visits up to Month 12, with a 56% risk reduction in persistent vision loss with IZERVAY vs sham
Cumulative Rate of Vision Loss
- Masked image and adverse event analysis completed to further ensure vision loss was consistent with disease progression1
- Given the exploratory, post hoc nature of the data, these results should be interpreted with caution and cannot be considered conclusive
IZERVAY was evaluated across the GATHER clinical trials
The efficacy and safety of IZERVAY were evaluated in 2 randomized, multi-center, double-masked, sham-controlled clinical trials.1
In GATHER1 and GATHER2, patients were randomized to receive either intravitreal injections of IZERVAY or sham once monthly.
- Unifocal and multifocal
- Within 1500 μm from the foveal center
- Ranging in size from 2.5 mm2 to 17.5 mm2
