About this study
Since the initial description, the therapeutic efficacy of CsA for human KCS has been well documented, with evidence ranging from several small single center randomized double-masked clinical trials to several large multicenter randomized, double-masked clinical trials.(10-12) Therefore, the aim of the work is to evaluate the effect of using topical CsA in treatment of moderate to severe dry eye.
Read the detailed description
Dry eye disease (DED) is known to be among the most frequently occuring ocular morbidities. It is a growing public health concern affecting 25% of patients who visit ophthalmic clinics.For many years, DED was considered to be limited to dryness of the eyes due to decrease in the aqueous phase in the tear film. In 2007, the International Dry Eye Workshop discussed the definition and classification of DED and developed a new vision for the definition and the three-part classification of DED on the basis of etiology, mechanism, and severity of DED. Moreover, DED can be episodic or chronic. Episodic DED occurs when environmental or visual tasks with reduced blinking overwhelm the stability of the tear and produce symptomatic DED. Chronic DED, although aggravated by the same environmental conditions, persists continuously with symptoms and possible damage to the ocular surface. Because the tear film in DED patients is not stable and incapable to maintain the protective qualities that are important for its structure and function, patients usually experience the discomfort manifestations associated with DED such as burning, stinging, foreign body sensation, ocular fatigue, grittiness, tearing, and dryness. Patients may complain of symptoms of DED in the presence or absence of the known signs and DED may be diagnosed based only on the signs observed by a healthcare professional in the absence of symptoms reported by the patients.Since the initial description, the therapeutic efficacy of CsA for human KCS has been well documented, with evidence ranging from several small single center randomized double-masked clinical trials to several large multicenter randomized, double-masked clinical trials.Therefore, the aim of the work is to evaluate the effect of using topical CsA in treatment of moderate to severe dry eye.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Topical Cyclosporine ADrug
In our study we used 0.05% CsA prepared in castor oil by transferring (20ml ) of sterile castor oil in a sterile glass vial under laminar flow, removing a volume (400ul)of oil with micropipette (sterile tips), and replacing this volume with an equal volume of alcoholic CsA solution [200mg cyclosporine in 8 ml ethanol (96%)] under laminar flow.
PlaceboDrug
Placebo
| Study group | Role | What they receive |
|---|---|---|
| Topical CsA | Experimental | Group A received topical CsA 0.05% for 3 months Receives: Drug: Topical Cyclosporine A |
| Control | Placebo comparator | Placebo group Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Tear Break up Time
Measuring the time lapse between last blink after instillation of fluorescein and appearance of the first dry spot on the corneal surface
Measured: 3 months
Secondary outcomes (4)
Schirmer test
It was performed by placing a thin strip of filter paper in the inferior cul-de-sac following the instillation of topical anesthetic; then, the eyes are closed for 5 minutes, and the amount of wetting of the paper strip is measured. Measurement of less than 5mm is abnormal; 5-10 mm is equivocal.
Measured: 3 months
Intra ocular pressure
Intra ocular pressure measurement by applanation tonometery
Measured: 3 months
Fluorescein staining (Oxford Grading Scale)
graded on a scale from 0 = none to 5 = severe by Oxford grading system
Measured: 3 months
OSDI Scores
The OSDI is a valid and reliable instrument for measuring the severity of dry eye disease. Subjects in the study completed the OSDI Questionnaire each visit.
Measured: 3 months

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Topical Cyclosporine A in people with Dry Eye, run by Alexandria University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Tear Break up Time (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jan 2021.
