Trial summary

Vernal keratoconjunctivitis (VKC) is a bilateral, chronic, external ocular inflammatory disease of unknown cause. It is a fairly common disease in hot, dry environments, representing as much as 3% of severe ophthalmic diseases and up to 33% of all eye pathology seen among young patients in eye clinics in Central… Read more about this study

About this study

Official title: Topical Cyclosporine in the Treatment of Vernal Keratoconjunctivitis in a Rwandan Eye Clinic; a Prospective Randomized Double-masked Clinical Trial

Vernal keratoconjunctivitis (VKC) is a bilateral, chronic, external ocular inflammatory disease of unknown cause. It is a fairly common disease in hot, dry environments, representing as much as 3% of severe ophthalmic diseases and up to 33% of all eye pathology seen among young patients in eye clinics in Central Africa. Symptoms and signs can persist for years with an important visual morbidity and social impact. Corneal changes (e.g. corneal ulcers) can be sight threatening, occurring in up to 10% of VKC children. Topical steroid therapy remains the current standard treatment, but in developing countries its use often is chronic and not medically supervised, potentially leading to bacterial infections, steroid-induced glaucoma and cataract. Chromoglycate drops have less side effects but lack the power to control a flare-up. Topical cyclosporine has the potential to offer an efficient but safer alternative to steroid drops in the management of VKC in an African setting. Its safety and efficiency in the management of vernal keratoconjunctivitis have been described in several uncontrolled studies and double-blind, placebo-controlled trials, but those studies were relatively small and involved populations outside Africa with predominantly palpebral and mixed forms of VKC. Controversy still remains on the efficiency of cyclosporine in severe forms of allergic conjunctivitis like VKC. We therefore undertake a larger prospective randomized double-masked, standard treatment controlled clinical trial in Central Africa to compare the short-term efficiency of cyclosporine A (CsA) 2% eye drops, solved in olive oil vehicle, with that of steroid drops in predominantly limbal forms of VKC. During 4 weeks the participants will be randomised to either cyclosporine or dexamethasone as attack treatment for VKC. The 4 weeks thereafter all participants will receive chromoglycate drops as maintenance treatment. Additional objectives are to document any difference in rebound phenomenon while on chromoglycate during the maintenance phase between the 2 treatment groups and to evaluate safety and tolerance of the test medication.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Difference in score for symptoms and clinical signs between treatment arms

    Differences in scores for symptoms and clinical signs individually and as a composite score between the treatment arms.

    Symptoms are itchiness, tearing, stinging, discharge and photophobia. Signs are subtarsal scarring, limbal cysts, pseudogerontoxon, pseudomembrane, corneal plaque, shield-ulcer, bulbar hyperaemia, limbal pigmentation, punctate keratitis, tarsal plate papillae, corneal astigmatism, limbal follicles, conjunctivalisation of the cornea and trantas dots.

    Measured: After 4 weeks at the end of 4 weeks test medication

Secondary outcomes (2)
  1. Speed of symptom/sign reduction

    To document any difference between the 2 treatment groups in speed of symptom/sign reduction during the attack treatment and in rebound phenomenon while on chromoglycate during the maintenance phase

    Measured: At 2 weeks while on test medication and at 8 weeks at the end of a chromoglycate maintenance phase

  2. Safety and tolerance of the test medication

    To evaluate safety and tolerance of the test medication.

    Measured: At 2 weeks while on test medication and at 8 weeks at the end of a chromoglycate maintenance phase

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Cyclosporine A and Dexamethasone in people with Vernal Keratoconjunctivitis, run by University Hospital, Ghent at 1 site in Rwanda.

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 4 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 29 Sep 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Rwanda. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Difference in score for symptoms and clinical signs between treatment arms (time frame: After 4 weeks at the end of 4 weeks test medication). 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 29 Sep 2010.
