Accepts Healthy Volunteers:   No


  • Have a score of at least 2 ("some of the time") on the subject-assessed Symptom Eligibility question; see Section 8.5.1.
  • Have a sodium fluorescein corneal staining sum of ≥ 3 in either eye; see Section 8.5.10.
  • Have a best-corrected visual acuity of 0.6 log MAR or better in each eye as assessed using an ETDRS chart; see Section 8.5.7.


  • Have a history or current evidence of the following: epithelial herpes simplex keratitis (dendrictic keratitisis); vaccinia, active or recent varicella viral disease of the cornea and/or conjunctiva; ocular rosacea; acute or chronic bacterial disease of the cornea and/or conjunctiva and/or eyelids; mycobacterial infection of the eye; and/or fungal disease of the eye.
  • Use of Restasis® (cyclosporine ophthalmic emulsion, 0.05%) within 30 days of Visit 1.
  • Use of systemic medications that may contribute to dry eye if the dosing regimen has not been stable for at least 30 days prior to Visit
