Primary Outcome Measures:
  • Change from baseline (Visit 2) to Day 29 (Visit 4) in the subject-completed symptom questionnaire. [ Time Frame: 29 days ]

Secondary Outcome Measures:
  • Change from baseline (Visit 2) to Day 29 in total symptom scores [ Time Frame: 29 days ]
  • Change from baseline to day 29 in total fluorescein and Lissamine green staining of the cornea and conjunctiva, respectively. [ Time Frame: 29 days ]
  • The proportion of subjects with at least a 20% improvement from baseline to Day 29 in symptom scores [ Time Frame: 29 days ]
  • The proportion of subjects with at an improvement following 14 and 28 days of treatment in symptom scores [ Time Frame: 28 days ]
    Changes from baseline to Day 15 will also be assessed.

  • Safety will be assess by the number of AEs from screening to Day 28 [ Time Frame: 28 days ]

Detailed Description:
This is a multi-center, randomized, double-masked, placebo-controlled, parallel group Phase 2b trial designed to evaluate symptoms and signs in subjects with mild to moderate dry eye disease. Eligible patients, will be treated with placebo during 2-week placebo run-in period. Subjects will then be randomly assigned in a double-masked, 1:1 ratio to either 0.017% P-321 Ophthalmic Solution or placebo TID for 28 days. This study is designed to evaluate the changes in symptoms. Safety will be assessed throughout the study by adverse events.
