Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ocular Itching Score at Day 1 | Day 1 | The participant evaluated ocular itching in both eyes 5 minutes post conjunctival allergen challenge (CAC) (8 hours post-dose) at Day 1 using a 9-point scale in half-unit increments where: 0=none to 4=incapacitating itch with an irresistible urge to rub. The score for each participant was the average of the score of both eyes. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Ocular Itching Score at Day 15 | Day 15 | The participant evaluated ocular itching in both eyes 5 minutes post conjunctival allergen challenge (16 hours post-dose) at Day 15 using a 9-point scale in half-unit increments where: 0=none to 4=incapacitating itch with an irresistible urge to rub. The score for each participant was the average of the score of both eyes. |
| Conjunctival Hyperemia Score | Day 1 | Conjunctival hyperemia is the engorgement of the blood vessels (redness) of the clear membrane covering the white surface of the eye. Conjunctival hyperemia was evaluated 15 minutes post conjunctival allergen challenge (CAC) (8 hours post dose) on Day 1 for both eyes using a 9-point scale in half-unit increments where: 0=none to 4=Extremely severe. The score for each participant was the average of the score of both eyes. |

Outcome results
Ocular Itching Score at Day 1
The participant evaluated ocular itching in both eyes 5 minutes post conjunctival allergen challenge (CAC) (8 hours post-dose) at Day 1 using a 9-point scale in half-unit increments where: 0=none to 4=incapacitating itch with an irresistible urge to rub. The score for each participant was the average of the score of both eyes.
Time frame: Day 1
Population: Modified Intent-to-treat (MITT) population included all randomized participants with ocular itching score data available for this time point
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| AGN-229666 Dose A | Ocular Itching Score at Day 1 | 0.500 Score on a scale | Standard Deviation 0.5123 |
| AGN-229666 Dose B | Ocular Itching Score at Day 1 | 0.319 Score on a scale | Standard Deviation 0.3947 |
| Vehicle of AGN-229666 | Ocular Itching Score at Day 1 | 1.867 Score on a scale | Standard Deviation 0.9485 |
Conjunctival Hyperemia Score
Conjunctival hyperemia is the engorgement of the blood vessels (redness) of the clear membrane covering the white surface of the eye. Conjunctival hyperemia was evaluated 15 minutes post conjunctival allergen challenge (CAC) (8 hours post dose) on Day 1 for both eyes using a 9-point scale in half-unit increments where: 0=none to 4=Extremely severe. The score for each participant was the average of the score of both eyes.
