Study Endpoints

Primary Endpoints

Mean Ocular Itching at Onset of Action
Day 14 (3, 5, and 7 minutes post-CAC)

A treatment efficacy CAC was performed 27 minutes after drop installation. Ocular itching was assessed by the participant on a 0-4 scale (0= none, 4 = incapacitating itch). Average of ocular itching score over both eyes was analyzed.

Mean Ocular Itching at 24 Hours Duration of Action
Day 1 (3, 5, and 7 minutes post-CAC)

A treatment efficacy CAC was performed 24 hours after drop instillation on Day 0. Ocular itching was assessed by the participant on a 0-4 scale (0= none, 4 = incapacitating itch). Average of ocular itching score over both eyes was analyzed.

Adverse Events
An average of 6 weeks

An adverse event was defined as any untoward medical occurrence in a subject administered a study treatment regardless of causal relationship with the treatment. AEs were obtained as solicited comments from the study subjects and as observations by the study Investigator.

Mean Ocular Itching at 16 Hours Duration of Action
3, 5, and 7 minute timepoints, post-CAC on Day 14 of receiving treatment

A treatment efficacy CAC was performed 16 hours after drop instillation. Ocular itching was assessed by the patient on a 0-4 scale (0=none to 4=incapacitating itch). Average of ocular itching score over both eyes was analyzed.

Secondary Endpoints

Mean Conjunctival Redness at Onset of Action
Day 14 (7, 15, and 20 minutes post-CAC)
Mean Conjunctival Redness at 24 Hours Duration of Action
Day 1 (7, 15, and 20 minutes post-CAC)
Mean Total Redness at Onset of Action
