# FutureHouse's Robin multi-agent system proposes ripasudil as a new treatment candidate for dry AMD

FutureHouse's Robin generated the hypotheses, analyses and figures that identified ripasudil, a glaucoma drug, as a candidate for dry age-related macular degeneration. Ripasudil increased phagocytosis in retinal pigment epithelium cells and upregulated ABCA1 about 3×. Humans ran the bench work; the project took 2.5 months. Published in Nature on 19 May 2026.

## Key facts
- Robin proposed enhancing RPE phagocytosis as a mechanism, then ripasudil (ROCK inhibitor) as the drug
- ABCA1 upregulated ~3× (RNA-seq follow-up proposed by Robin)
- Caveat: Robin's analysis agent reported a 7.5× phagocytosis effect; human re-analysis of the same data gave 1.75×
- No clinical data; in vitro only

## What happened

Robin chained literature-search and data-analysis agents to go from disease to mechanism to drug candidate, with human lab work in between.

## Why it matters

It was an early end-to-end AI-driven discovery loop in biology. The overstated effect size is a reminder that AI analyses need human re-checking.
