Corneal Endothelial
Cell Therapy

Our initial candidate treats dystrophies that cause corneal blindness.


In Japan, early clinical research1 followed by dose-ranging and confirmatory clinical trials have successfully demonstrated the safety, efficacy, and tolerability of our lead product candidate. We have received regulatory approval from Japan’s PMDA.

In the US, we have completed enrollment and dosing of our Phase 1 /2 trial, and expect topline results in early 2025. We are in process of clinical development planning for the EU.
