Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Arm && Interventions

Group	Intervention	Description
Voclosporin ophthalmic solution (VOS)	Voclosporin Ophthalmic Solution	0.2% VOS, Twice Daily (BID), both eyes for 28 days
Comparator	Restasis®	0.05% cyclosporine ophthalmic emulsion (Restasis®) BID, both eyes for 28 days

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Drop Discomfort Post Dose Instillation on Day 1	1-minute Post Dose 1 installation (Day 1)	Drop Discomfort was assessed using the Individual Symptom Severity Assessment Visual Analog Scale (VAS) where the subject will complete the assessment 1 minute post-instillation on Day 1. The VAS scale is 0 - 100, where 0 corresponds to "no discomfort" and 100 corresponds to "maximal discomfort".

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Foreign Body Sensation Post Dose Instillation on Day 28	28 days	Foreign Body Sensation was assessed using the Individual Symptom Severity Assessment Visual Analog Scale (VAS) where the subject will complete the assessment post-instillation on Day 28. The VAS scale is 0 - 100, where 0 corresponds to "no foreign body sensation" and 100 corresponds to "worst foreign body sensation".
Change From Baseline in Itching Post Dose Instillation on Day 28	28 days	Itching was assessed using the Individual Symptom Severity Assessment Visual Analog Scale (VAS) where the subject will complete the assessment post-instillation on Day 28. The VAS scale is 0 - 100, where 0 corresponds to "no itching" and 100 corresponds to "worst itching".
Change From Baseline in Drop Discomfort Post Dose Instillation on Day 28	Day 28	Drop Discomfort was assessed using the Individual Symptom Severity Assessment Visual Analog Scale (VAS) where the subject will complete the assessment 1 minute post-instillation on Day 28. The VAS scale is 0 - 100, where 0 corresponds to "no discomfort" and 100 corresponds to "maximal discomfort".
Change From Baseline in Eye Dryness Post Dose Instillation on Day 28	28 days	Eye dryness was assessed using the Individual Symptom Severity Assessment Visual Analog Scale (VAS) where the subject will complete the assessment post-instillation on Day 28. The VAS scale is 0 - 100, where 0 corresponds to "no eye dryness" and 100 corresponds to "worst eye dryness".
Change From Baseline in Fluorescein Corneal Staining (FCS) Score	28 days	The FCS score was summarized for each eye separately. Each of the 5 sections of cornea (superior, inferior, nasal, temporal, central) were graded using the National Eye Institute (NEI) scale; 0, 1 (mild), 2 (moderate), or 3 (severe). The total score was obtained by summing each of the 5 sections of the cornea from 0 - 15. Lower scores indicate less staining and therefore a better outcome.
Change From Baseline in Burning/Stinging Post Dose Instillation on Day 28	Day 28	Burning/Stinging was assessed using the Individual Symptom Severity Assessment Visual Analog Scale (VAS) where the subject will complete the assessment post-instillation on Day 28. The VAS scale is 0 - 100, where 0 corresponds to "no burning/stinging" and 100 corresponds to "worst burning/stinging".
Change From Baseline in Photophobia Post Dose Instillation on Day 28	28 days	Photophobia was assessed using the Individual Symptom Severity Assessment Visual Analog Scale (VAS) where the subject will complete the assessment post-instillation on Day 28. The VAS scale is 0 - 100, where 0 corresponds to "no photophobia" and 100 corresponds to "worst photophobia".
Change From Baseline in Eye Pain Post Dose Instillation on Day 28	28 days	Eye pain was assessed using the Individual Symptom Severity Assessment Visual Analog Scale (VAS) where the subject will complete the assessment post-instillation on Day 28. The VAS scale is 0 - 100, where 0 corresponds to "no eye pain" and 100 corresponds to "worst eye pain".
Change From Baseline in Symptom Assessment in Dry Eye Score (SANDE)	Day 28	The Symptom Assessment in Dry Eye (SANDE) is a subjective rating performed by the subjects for the frequency and severity of their dry eye symptoms. The total length of the line is 100mm. For Frequency of Symptoms 0mm = "rarely" and 100mm = "all the time". For Severity of Symptoms 0mm = "very mild" and 100mm = "very severe". Subjects were asked to subjectively rate the frequency and severity of their symptoms by placing an "X" on the relevant horizontal line. The length of the line between the "rarely" or "very mild" starting point and the first point where the subject's mark crosses each line was measured and recorded in millimeters.
Change From Baseline in Unanesthetized Schirmer Test Score	28 days	The Schirmer Test Score recorded tear production on test strips. The Schirmer tear test was conducted 1 hour following administration of VOS/Comparator and 20 minutes following fluorescein corneal staining. Using a ruler and/or the millimeters recorded on the strips, a point halfway between the two lines was measured and this was recorded as the amount of wetting. Lower scores indicate less tear production and therefore a worse outcome. Normal tear production is ≥10mm of wetting on the test strip, and severe dry eye is \<5mm of wetting on the test strip.
Change From Baseline in the Total of All Individual Symptom Severity Assessment Scores	Day 28	The Individual Symptom Severity Assessment Visual Analog Scale (VAS) includes Burning/Stinging (scale 0 - 100; 0 = no Burning/Stinging, 100 = worst Burning/Stinging), Foreign Body Sensation (scale 0 - 100; 0 = no Foreign Body Sensation, 100 = worst Foreign Body Sensation), Photophobia (scale 0 - 100; 0 = no Photophobia, 100 = worst Photophobia), Eye Pain (scale 0 - 100; 0 = no Eye Pain, 100 = worst Eye Pain), Eye Dryness (scale 0 - 100; 0 = no Eye Dryness, 100 = worst Eye Dryness), and Itching (scale 0 - 100; 0 = no Itching, 100 = worst Itching). The total sum of all 6 symptoms (Burning/Stinging, Foreign Body Sensation, Photophobia, Eye Pain, Eye Dryness, Itching) were evaluated (scale 0 - 600; 0 = no visual symptoms, 600 = worst visual symptoms).
