Brief summary

Evaluation of safety and efficacy of PL9643 Ophthalmic Solution compared to placebo for the treatment of the signs and symptoms of dry eye.

Detailed description

The clinical trial is a Phase 2, multi center, randomized, double masked and placebo controlled study. During a 14-day study run-in period (for the purpose of subject selection) prior to randomization, all subjects will receive Placebo Ophthalmic Solution (vehicle) bilaterally. During the screening period, exposure to the CAE® will be conducted to ascertain eligibility to enter the study at Visit 1 and Visit 2. Those who qualify at Visit 2 will be randomized to receive study drug in a double-masked fashion for 12 weeks. The CAE® exposure will occur at all Visits.

Interventions

PL9643 Ophthalmic Solution as topical ophthalmic drops administered bilaterally for 12 weeks.

DRUGPlacebo Ophthalmic Solution
