Can Oral Gildeuretinol Slow Advanced Macular Degeneration?
Although the trial missed its primary endpoint, exploratory analyses suggested slower lesion growth and better functional outcomes with gildeuretinol.

1
Oral gildeuretinol acetate did not significantly slow geographic atrophy progression compared to placebo in age-related macular degeneration patients.
2
The phase 2/3 SAGA trial involved 198 patients aged 60 and older, assigned to receive either gildeuretinol or placebo for 24 months.
3
Geographic atrophy lesion growth was reduced by 13% with gildeuretinol, but this difference was not statistically significant.
4
Secondary outcomes showed exploratory benefits for gildeuretinol, including less decline in low-luminance visual acuity and improved quality of life.
5
The study's primary endpoint was not met, and researchers emphasized that secondary findings are exploratory and require further investigation.
