Outcomes

Primary Outcome Measures

Number of Subjects Who Achieved Complete Clearing of Corneal Staining (i.e., Total Corneal FS Score = 0) at Week 24
Complete clearing of corneal staining by fluorescein staining (FS). The primary efficacy analysis was performed for 1eye (target eye), defined as the eye with the larger corneal FS value at Baseline. If both eyes had the same corneal FS value at baseline, the target eye was considered the eye with the larger central corneal staining value at Baseline. Corneal FS defined as a corneal punctate fluorescein staining score of ≥4 in either eye by the National Eye Institute evaluation scale summed over 5 areas each with a 0-3 scoring scale
Number of Subjects With Adverse Events
Determine the safety of oral CF 101 in this subject population. Adverse Events (AEs) and changes in vital signs, physical examination, clinical laboratory tests (liver, kidney, hematology, chemistry and urinalysis), electrocardiogram (ECG) findings, slit lamp and ophthalmic examination, visual acuity, and intraocular pressure measurements.

Secondary Outcome Measures

Number of Subjects Who Achieve an Increase in Schirmer Test Tearing by >9mm Over Baseline
ST wetting increase over Baseline of ≥10 mm with or without anesthesia in either eye at Week 24, using a strip of filter paper placed inside the lower eyelid
Ocular Surface Disease Index
The Ocular Surface Disease Index is assessed on a scale of 0 to 100, with higher scores representing greater disability. The subtotal score is based on 12 questions with answers ranging from 0 - "none the time," to 4 - "all of the time." The number of questions answered is totaled (0 - 12). The OSDI is calculated using the sum of subtotal scores (0-48) multiplied by 25, divided by number of questions answered (0-12). (i.e., if a participant answers all 12 questions with a severe outcome of 4, their respected OSDI = [(4 x 12) x 25] / 12 = [48 x 25] / 12 = 100) The outcome measured is the Mean Change from Baseline in Ocular Surface Disease Index at Week 24

5. Study Description

Brief Summary
Eligible patients with dry eye will be treated with CF101 or placebo twice daily for 24 weeks. Disease activity will be assessed using evaluations of ocular surface integrity, tear production, and patient symptoms.
Detailed Description
Patients will be randomized to receive either CF101 0.1 mg, CF101 1.0 mg, or matching placebo, given orally twice daily (BID) for 24 weeks. A Screening Period of up to 4 weeks that includes a 2-week run-in period will precede a 24-week treatment period, followed by a 2-week follow-up period. At a Screening Visit, patients will undergo complete medical and ophthalmologic history, medication history, physical examination (including height, weight, sitting blood pressure, pulse rate and temperature), ophthalmic examination, and clinical laboratory tests. Disease activity will be assessed using fluorescein staining, Schirmer test with and without anesthesia, Ocular Surface Disease Index©, and tear break-up time. Eligible patients will begin a 2-week run-in period during the 4-week screening period, during which time they will be instructed to discontinue use of all topical ophthalmic medications except for REFRESH TEARS® Lubricant Eye Drops. At the Baseline Visit, patients who successfully complete the 2-week run-in period and re-qualify for entry will be randomized to their assigned medication (CF101 0.1 mg, CF101 1.0 mg, or matching placebo) to be taken orally twice daily BID for 24 weeks. Patients will return for assessments and a new supply of study medication at Weeks 2, 4, 8, 12, 16, and 20; at Week 24 for a final on-treatment assessment; and at Week 26 for the 2-week off-treatment follow-up visit.
