Study Description

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.

Condition or disease	Intervention/treatment	Phase
Dry Eye Disease	Drug: PL9643 Ophthalmic Solution; Drug: Placebo Ophthalmic Solution	Phase 2

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.

   An assessment of corneal fluorescein staining using the 0 [none] to 4 [worst] Ora Calibra Scale prior to and following exposure to a challenge in a controlled adverse environment (CAE)
2. Ocular Discomfort Using The Ora Calibra Scale [ Time Frame: Day 85 ]
   A patient-reported subjective assessment of ocular discomfort using the 0 [none] to 4 [worst] Ora Calibra Scale recorded at each study visit throughout the treatment period

Secondary Outcome Measures :

1. Corneal Fluorescein Staining Using The Ora Calibra Scale [ Time Frame: 12 weeks ]
   An assessment of corneal fluorescein staining using the 0 [none] to 4 [worst] Ora Calibra Scale prior to and following exposure to a challenge in a controlled adverse environment (CAE)
2. Conjunctival Lissamine Green Staining Using The Ora Calibra Scale [ Time Frame: 12 weeks ]
   An assessment of conjunctival lissamine green staining using the 0 [none] to 4 [worst] Ora Calibra Scale prior to and following exposure to a challenge in a controlled adverse environment (CAE)
3. Conjunctival Redness Using The Ora Calibra Scale [ Time Frame: 12 weeks ]
   An assessment of conjunctival redness using the 0 [none] to 4 [worst] Ora Calibra Scale prior to and following exposure to a challenge in a controlled adverse environment (CAE)
