Results
- Irritation parameter:
- cornea opacity score
- Basis:
- other: eye bovine
- Time point:
- other: 240
- Score:
- >= 2.2 - <= 2.6
- Max. score:
- 2.6
- Other effects:
- The corneas were all clear after the 240 minutes of treatment with WAY-188471. Hence, the in vitro irritancy scores ranged from 2.0 to 2.6 after 240 minutes of treatment with WAY-188471.
