Active clinical trials for "Conjunctivitis, Allergic"

The purpose of this 2-year study is to assess the sustained clinical efficacy and safety of 300 IR/day of a sublingual solution of birch pollen allergen extract starting 4 months prior to the birch pollen season and continuing over the birch pollen season compared with placebo for reduction of rhinoconjunctivitis-related symptoms and anti-allergy medication usage.

Ectoin acts on membranes by forming an Ectoin-Hydro-Complex therewith providing a protection against external agents like aeroallergens. The effects of Ectoin containing nasal spray and eye drops have already been demonstrated in several studies with adult Seasonal Allergic Rhinitis (SAR) patients and it was shown that they can effectively reduce symptoms of allergic rhinitis without resulting in any significant adverse events. The aim of this clinical investigation is to demonstrate the safety, tolerability and efficacy of Ectoin Nasal Spray and Ectoin Eye Drops in pediatric and adolescent SAR patients. It is assumed that Ectoin containing products show an excellent safety profile and very good tolerability together with a potent efficacy in the treatment of SAR.

The purpose of this study is to evaluate the onset and duration of action of AC-170 0.24% compared to vehicle in the prevention of the signs and symptoms of allergic conjunctivitis in the conjunctival allergen challenge (CAC) model.

This study will evaluate the safety and efficacy of AGN-229666 for the treatment of seasonal or perennial allergic conjunctivitis.

The purpose of this study is to find the optimal dose of AllerT that should be used to treat moderate to severe allergies due to birch tree pollen. There are 4 treatment groups in this study; 3 treatment groups will receive AllerT at different doses and 1 treatment group will receive placebo. This study will also assess the effectiveness and safety of AllerT compared to placebo in relieving allergy symptoms.

This study will investigate the safety and efficacy of olopatadine hydrochloride / ketorolac tromethamine fixed dose combination ophthalmic solution compared with olopatadine hydrochloride ophthalmic solution in patients with seasonal allergic conjunctivitis.

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.

Multicentre, Double blind, Randomized, Comparative Study(comparing N-acetyl-aspartyl-glutamic acid(NAAGA) in Abak preservative free device versus SALINE in Abak preservative free device. Evaluation of the effects and safety of NAABAK® through inflammation markers and symptoms in patients with allergic conjunctivitis and dry eye syndrome after 3 months treatment. The patients will attend 4 visits.

This study is to evaluate the safety and efficacy of Alrex (LE ophthalmic suspension, 0.2%) versus Patanol (olopatadine hydrochloride ophthalmic solution, 0.1%) in the temporary relief of the signs and symptoms of Seasonal Allergic Conjunctivitis (SAC).

The purpose of this study was to assess the safety and efficacy of AL-4943A ophthalmic solution for the treatment of ocular itching associated with allergic conjunctivitis using the Conjunctival Allergen Challenge (CAC) model.
