Novel Use of Cyclosporine Ophthalmic Emulsion 0.05% in a PROSE Device

Phase 1

Completed

Conditions: Ocular Surface Disease

Interventions: Drug: Restasis

Registration Number: NCT04918823

Lead Sponsor: Boston Sight

Brief Summary: The goal of this prospective observational pilot study is to evaluate the tolerability and safety of RESTASIS (cyclosporine ophthalmic solution 0.05%) when added to the PROSE (Prosthetic Replacement of the Ocular Surface Ecosystem) lens reservoir in patients with ocular surface disease (OSD). Secondary endpoints include early (1-month) efficacy data for ocular signs and symptoms.

Detailed Description: For this study, all subjects will receive Restasis (Cyclosporine ophthalmic emulsion 0.05%). One drop of the dispensed study drop will be instilled in the PROSE lens reservoir twice a day and the remainder of the reservoir will be filled with normal saline (0.9% sodium chloride solution). In order to standardize solutions used in the PROSE reservoir, all patients recruited will be either currently using or will be switched to buffered preservative-free normal saline (Purilens, Lifestyle Inc., pH 7.46 ) to better match the reported pH of RESTASIS (pH 6.5-8.05 ).

Outcomes will include subjective responses regarding the subject's symptoms and visual function in addition to the objective assessments of the health of the ocular surface seen on clinical examination. Results will be measured at baseline, after 1 week, and after 1 month of the study.

Primary Outcome Measures

Name	Time	Method
Ocular Surface Disease Index (OSDI) Score Change (1 Month Post Treatment Initiation)	1 month post initiation change in OSDI score	The Ocular Surface Disease Index (OSDI) is assessed on a scale of 0 to 100, with higher scores representing greater disability. The index demonstrates sensitivity and specificity in distinguishing between normal subjects and patients with dry eye disease.
Corneal Staining	at baseline and at 1-month post treatment initiation	Corneal fluorescein staining, pre and post initiation of 0.05% cyclosporine treatment, is measured using the National Eye Institute (NEI) grading system. The NEI grading scale is a system for grading corneal fluorescein staining which divides the corneal surface into 5 areas \[central, superior, nasal, inferior, temporal\]. A standardized grading system of 0 to 3, with 0 being no staining (better outcome) and 3 being severe staining (worse outcome), is used for each of the areas of cornea. The scores from each corneal area are totaled to determine the total corneal staining score in each eye. The total corneal staining score has a minimum score of zero (better outcome) and a maximum score of 15 (worse outcome) for an individual eye.
Conjunctival Staining	baseline and 1-month post treatment initiation	Conjunctival fluorescein staining, pre and post initiation of 0.05% cyclosporine treatment, is measured using the National Eye Institute (NEI) grading system. The NEI grading scale is a system for grading conjunctival fluorescein staining which divides the conjunctival surface into 6 areas. A standardized grading system of 0 to 3, with 0 being no staining (better outcome) and 3 being severe staining (worse outcome), is used for each of the areas of conjunctiva. The scores from each conjunctival area are totaled to determine the total conjunctival staining score in each eye. The total conjunctival staining score has a minimum score of zero (better outcome) and a maximum score of 18 (worse outcome) for an individual eye.
Visual Acuity	at baseline and 1-month post treatment initiation	Subjects vision was tested using Snellen visual acuity chart (converted to LogMAR scale) pre and post initiation of 0.05% cyclosporine treatment. The LogMAR scale ranges from +3.00 to -0.30. A Zero LogMAR indicates standard 20/20 vision. More negative logMAR scale vision indicates better vision. More positive logMAR scale vision indicates worse vision. Legal blindness is defined as a best-corrected visual acuity of +1.0 LogMAR pr worse in the better seeing eye.
Conjunctival Redness	baseline and one month post treatment initiation	The Efron Grading Scales for Contact Lens Complications includes a standardized method for quantifying the level of conjunctival redness noted on slit lamp examination. The scale ranges, in whole numbers, from 0 to 4, with 0 indicating that conjunctival redness is not present (better outcome) and 4 indicating that the most severe redness is present (worse outcome).
Tolerability Questionnaire Score	baseline and one month post initiation treatment	Subjects completed questionnaires regarding PROSE device comfort and fit (Tolerability Questionnaire, scale 0 to 10, higher score means better outcome), measured pre and post initiation of 0.05% cyclosporine treatment. Total tolerability score is a composite score sum of SIX questions (maximum score of 60).
Automated Conjunctival Redness Without PROSE Device on the Eye	baseline and one month post treatment initiation	Conjunctival redness score measured using the automated imaging system Keratograph 5M R-Scan. The Keratograph 5M R-scan is an imaging device which classifies bulbar and limbal conjunctival redness. The R-Scan detects blood vessels in the conjunctiva and evaluates the degree of redness. The minimum score per eye is 0 (no redness present, better outcome), while the maximum score per eye is 4 (most severe redness present, worse outcome).
