* Women who are pregnant, nursing or planning a pregnancy * Unwillingness to submit a urine pregnancy test at screening and the last visit (or early termination visit) if of childbearing potential, or unwillingness to use acceptable means of birth control * Clinically significant slit-lamp findings or abnormal lid anatomy at screening * Ocular/periocular malignancy * History of herpetic keratitis * Active ocular allergies or ocular allergies that may become active during the study period * Ongoing ocular or systemic infection at screening or baseline * Wear of contact lenses within 3 months prior to screening or anticipated use of contact lenses during the study * History of no response to previous topical Cyclosporine A and/or use of topical Cyclosporine A or Liftigrast within 2 months prior to screening * Intraocular surgery or ocular laser surgery within the previous 6 months, or have any planned ocular and/or lid surgeries over the study period * Presence of uncontrolled systemic diseases * Presence of known allergy and/or sensitivity to the study drug or its components

Design outcomes

Primary

MeasureTime frameDescription
Change From Baseline in Total Corneal Fluorescein Staining at Day 29baseline and 1 month [day 29]CFS was assessed in each eye using the National Eye Institute (NEI) scale. A standardized grading system of 0-3 is used for each of the five areas on each cornea. Grade 0 will be specified when no staining is present. The maximum total score for each eye is 15. Higher values describe greater staining and corneal damage.
Change From Baseline in Ocular Surface Disease Index at Day 29baseline and 1 month [day 29]The OSDI score is a composite measure built on 12 questions,with totals ranging from 0 to 100, and higher scores representing a worse disease index.
