This is a Phase 2, randomized, double-masked, placebo-controlled, parallel-group study in adult males and females, aged 18 years and over, with a diagnosis of moderate-to-severe keratoconjunctivitis sicca (KCS). Patients will be randomized to receive either CF101 1 mg or matching placebo, given orally every 12 hours (q12h) for 12 weeks. A Screening Period of up to 4 weeks that includes a 2-week run-in period will precede a 12-week treatment period, followed by a 2-week follow-up period.

Eligibility | Inclusion Criteria: - Male or female, 18 years of age and over; - Have a diagnosis of moderate-to-severe KCS as defined by: (1) Schirmer Test (ST) (without anesthesia) < 7 mm/5 min in either eye; AND (2) Positive FS, defined as a corneal punctate fluorescein staining score of =1 in either eye, where 0 = none and 3= severe; AND (3) At least 1 of the following ocular symptoms scored at =2, where 0 = none and 4 = very severe/interferes with normal activities: photophobia, blurred vision, foreign body sensation, soreness or pain, itching, burning, dryness; - Willing to use no topical ocular treatments except for the unpreserved artificial tears; - Doses of unpreserved artificial tears have been stable for >2 weeks prior to Screening Visit; - Females of child-bearing potential must have a negative urine pregnancy test at screening and throughout the study, to be eligible for, and continue participation in, the study; - Females of child-bearing potential must be willing to use 2 methods of contraception deemed adequate by the Investigator (for example oral contraceptive pills plus a barrier method) to be eligible for, and continue participation in, the study; - Ability to complete the study in compliance with the protocol; and - Ability to understand and provide written informed consent. Exclusion Criteria: - Has Sjögren's Syndrome with significant systemic non-exocrine gland involvement; - Has Stevens-Johnson Syndrome; - If KCS is due to rheumatoid arthritis or other autoimmune diseases, patient may not be receiving disease-modifying drugs, including methotrexate and biological agents; - Use of systemic immunosuppressive drugs; - Use of oral corticosteroids >10 mg prednisone, or equivalent, per day; - Use of topical steroids within 2 weeks prior to the Screening Visit and for the duration of the study; - Receipt of topical cyclosporine eye drops within 3 months prior to the Screening Visit and for the duration of the trial; - Presence of chronic ocular disease other than KCS requiring topical treatment; - Presence of post-burn ocular injury; - Ocular herpes simplex virus infection; - Concomitant use of contact lenses; - Persistent intraocular inflammation or infection; - Active blepharitis; - Recent surgical occlusion of the lacrimal puncta; - Subepithelial corneal scarring; - Anesthetic or neurotrophic corneas; - Hemoglobin level <9.0 gm/L; - Platelet count <125,000/mm^3; - White blood cell count <3500/mm^3; - Serum creatinine level outside the laboratory's normal limits; - Liver aminotransferase levels greater than 2 times the laboratory's upper limit of normal; - Pregnancy, planned pregnancy, lactation, or inadequate contraception as judged by the Investigator; - History of malignancy within the past 5 years (excluding basal cell carcinoma of the skin); - Significant acute or chronic medical, ophthalmic, or psychiatric illness that, in the judgment of the Investigator, could compromise patient safety, limit the patient's ability to complete the study, and/or compromise the objectives of the study; - Participation in another investigational drug or vaccine trial concurrently or within 30 days; or - Other conditions which would confound the study evaluations or endanger the safety of the patient. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change From Baseline to Week 12 in Schirmer Test (ST) Score in Millimeters | Involved placing a standardized paper tear strip inside the lower eyelid for 5 minutes. The tear strip was then removed and the length of the strip that was wet from tears was measured in millimeters. Change from baseline is calculated. Scores range 0-35 mm, with higher scores indicating more (better) tear production. | 12 weeks | |
Primary | Change From Baseline to Week 12 in Tear Break-Up Time (BUT) in Seconds | Time elapsed between a complete blink and the development of the first random dry spot on the tear film as seen under fluorescent light. Change from baseline is calculated. Scores range 0-30 seconds, with higher scores indicating better tear composition and function. | 12 weeks | |
Primary | Number of Subjects With >25% Improvement in Fluorescein Staining of the Cornea (FS) at Week 12 | Severity of corneal epithelial loss as graded by Fluorescein Staining of the cornea, assessed on a 0-4+ scale with 0 = none and 4+ = severe de-epithelialization (in other words, higher scores indicate worse disease), expressed as number of participants with >25% improvement at Week 12 relative to baseline. | 12 weeks | |
Secondary | Number of Subjects Experiencing Clinical Success at Week 12 | Proportion of subjects experiencing improvement of =25% over baseline at Week 12 in (a) tear breakup time (BUT), (b) superficial punctate keratitis as assessed by fluorescein staining (FS), or Schirmer Test (ST) | 12 weeks | |
Secondary | Change From Baseline to 12 Weeks in Dry Eye Symptom Score (DESS) | DESS consists of 12 questions designed to assess the symptoms of ocular irritation, covering three areas: ocular symptoms, environmental triggers and vision-related function. Each of the 12 symptoms can be graded 0-4, with 0 indicating no symptoms over the past week, and 4 meaning constant symptoms over the past week. Scores from all answered questions are summed. The final score is multiplied by (25/number of questions answered) to give an outcome between 0 (no symptoms) to 100 (worst possible symptoms). Change from baseline is calculated. | 12 weeks | |
Secondary | Change From Baseline to Week 12 in Tear Meniscus (TM) Height | Indicator of tear volume. TM was recorded on a scale from 0-3, with 0=none, 1=trace, 2=normal, and 3=high, with higher scores meaning better tear production and integrity. Change from baseline. | 12 weeks | |
Secondary | Percent Change From Baseline to Week 12 in the Use of Artificial Tears | Daily use of REFRESH TEARS® Lubricant Eye Drops artificial tears supplied to each patient was recorded in diaries provided to patients. Percent change from baseline is calculated. | 12 weeks |
