Active clinical trials for "Keratoconjunctivitis"

A Multi-Center, Phase 2/3, Randomized, Double-Masked, Parallel-Group, Vehicle-Controlled, Clinical Trial to Assess the Safety and Efficacy of Voclosporin Ophthalmic Solution (0.05%, 0.10%, 0.20%) Compared to Vehicle in Subjects with Dry Eye Syndrome.

The purpose of this study is to assess the safety and efficacy of 5% tavilermide and 1% tavilermide ophthalmic solutions compared with placebo ophthalmic solution in treating the signs and symptoms of dry eye.

To observe and compare the clinical efficacy of cyclosporine 0.05% eye drops with Loteprednol Etabonate 0.5% and Tobramycin Eye Drops 0.3% in the treatment of Vernal Keratoconjunctivitis in developing regions of China.

Dry eye disease (DED), also called keratoconjunctivitis sicca, is a multifactorial disease of the ocular surface characterized by loss of homeostasis of the tear film and accompanied by symptoms such as ocular discomfort and visual disturbance. Tear Film & Ocular Surface Society Dry Eye Workshop (TFOS DEWS) II recommends individualized management of DED based on the relative contribution of aqueous deficient and evaporative pathophysiology (to the extent that this can be determined), as well as disease severity. First-line for treating dry eye consists of over the counter (OTC) artificial tear drops, gels, ointments, or lubricants. Carboxymethyl cellulose (CMC) is one of the most common viscous polymers used in artificial tears to achieve prolonged residence time on the ocular surface. For these reasons, an interventional, non-comparative, single-center Post Marketing Clinical Follow-up (PMCF) study was planned to evaluate the performance and safety of "Ocular drops based upon carmellose" used as intended to relieve dry eye symptoms. The objectives of the PMCF study are confirmation of the performance, collection of additional safety data regarding expected adverse events and detection of potential unexpected adverse events associated with use of "Ocular drops based upon carmellose" according the Instructions for Use (IFU). Each subject, after signing the Informed Consent Form, will enter the screening and baseline phase (the 2 visits will coincide) during which baseline procedures will be completed. At baseline visit (V0), one of the "Ocular drops based upon carmellose" products can be dispensed to the enrolled subject, depending on Investigator clinical evaluation and decision. The patient will perform 2 on site visits: V0 and V2/EOS. To monitor the safety, 1 phone contact is planned (V1) to check for potential adverse events and concomitant medications intake. The first administration and the intervals at which the treatment should be repeated, to be done as per Investigator judgment and according the IFU, depend on various factors regarding the physiology of the patients (e.g. type of eye-tear film, anatomy, age), their lifestyle (e.g. use of computer, wearing of contact lenses) and their eye-surgery history (if applicable).

The purpose of this study is to evaluate whether, in people with dry eye syndrome, over the counter artificial tears and the prescription eye drop, dexamethasone, change or effect the eyes response to a low humidity environment. It is known that irritation from dry eye can be improved by over the counter artificial tears because they wet and lubricate the eyes. The prescription eye drop, dexamethasone, can also improve eye irritation by decreasing the inflammation that develops in dry eye. Thus, the investigators hypothesize that the use of these conventional dry eye treatments will improve the eyes' response to a low humidity environment.

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.

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.

The purpose of this study is to determine the outcomes of treating epidemic keratoconjunctivitis with 2% povidone-iodine.

Atopic keratoconjunctivitis (AKC) is a rare type of ocular allergy that is often associated with eczema. Over time, the complications from this disease process lead to loss of vision due to continual scarring of the corneal surface. The pathophysiology of AKC has not been fully elucidated, and the triggers are still unknown. Corticosteroids are very effective in controlling the acute symptoms of AKC. However, two thirds of patients managed with a combination of oral antihistamine, topical mast cell stabilizer, and intermittent topical steroid regimen eventually developed significant keratopathy and vision loss. Additionally, there are many side effects of corticosteroids, including local immunosuppression, cataract formation, and increased risk of glaucoma. Cyclosporin A is an immunomodulator that specifically inhibits T lymphocytes by blocking the expression of the interleukin-2 receptor. It also blocks the release of inflammatory mediators from mast cells and eosinophils. Cyclosporin has no known side effects except for burning upon instillation, and safe to use over long-term . The investigators have demonstrated that a 0.05% ophthalmic emulsion of cyclosporine has been shown to be effective at improving the ocular signs and symptoms of AKC over short-term. However, the long-term efficacy of cyclosporine A in slowing the natural history of AKC and possible steroid sparing effects have not been assessed. The investigators hypothesize that cyclosporine A can be used as a mainstay treatment of AKC to control signs and symptoms over a long period of time and also prevent the progression of this disease.
