Brief Summary:

This is a multi-center, double-masked, randomized, vehicle-controlled study testing PL9643, an opthalmic solution to determine if safe and efficacious for dry eye patients.

After a 2-week run-in period, patients will be randomized equally to the PL9643 opthalmic solution or vehicle opthalmic solution administered bilaterally three times a day for 12 weeks.

A Data Monitoring Committee will be engaged to review interim data.

Dry Eye Dry Eye Syndromes Drug: Vehicle Opthalmic Solution Drug: PL9643 Opthalmic Solution Phase 3

Detailed Description:

This is a multi-center, double-masked, randomized, vehicle-controlled study testing PL9643, an opthalmic solution, to determine the safety and efficacy against a comparator in dry eye patients.

During a 2-week/14-day study run-in period (for the purpose of subject selection) prior to randomization, all subjects will receive Vehicle Ophthalmic Solution (vehicle) bilaterally three times a day. Randomization will then occur as 1:1 where patients will be assigned to receive PL9643 ophthalmic solution given bilaterally three times a day or vehicle ophthalmic solution administered bilaterally three times a day. The treatment period is 12 weeks.
