Study Endpoints

Primary Endpoints

Mean change from baseline in investigator-assessed ocular redness at 15 minutes post-instillation on Day 1 (Visit 2) - Adult Cohort
Day 1 (Visit 2) pre-instillation; Day 1 (Visit 2) at 15 minutes post-instillation

Ocular redness will be assessed by the investigator using a 0-4 unit ocular hyperemia scale. This is a co-primary endpoint.

Mean change from baseline in investigator-assessed ocular redness at 10 hours (600 minutes) post-instillation on Day 1 (Visit 2) - Adult Cohort
Day 1 (Visit 2) pre-instillation; Day 1 (Visit 2) at 10 hours (600 minutes) post-instillation

Ocular redness will be assessed by the investigator using a 0-4 unit ocular hyperemia scale. This is a co-primary endpoint.

Mean change from baseline in investigator-assessed ocular redness at 1 hour (60 minutes) post-instillation on Day 1 (Visit 2) - Pediatric Cohort (12-17 years)
Day 1 (Visit 2) pre-instillation; Day 1 (Visit 2) at 1 hour (60 minutes) post-instillation

Ocular redness will be assessed by the investigator using a 0-4 unit ocular hyperemia scale.

Secondary Endpoints

Mean change from baseline in the investigator-assessed ocular redness at 1 minute post-instillation on Day 1 (Visit 2) - Adult Cohort
Day 1 (Visit 2) pre-instillation; Day 1 (Visit 2) at 1 minute post-instillation
Mean change from baseline in the investigator-assessed ocular redness at 8 hours (480 minutes) post-instillation on Day 1 (Visit 2) - Adult Cohort
Day 1 (Visit 2) pre-instillation; Day 1 (Visit 2) at 8 hours (480 minutes) post-instillation
Mean change from baseline in the investigator-assessed ocular redness at 12 hours (720 minutes) post-instillation on Day 1 (Visit 2) - Adult Cohort
Day 1 (Visit 2) pre-instillation; Day 1 (Visit 2) at 12 hours (720 minutes) post-instillation
