Active clinical trials for "Conjunctivitis, Allergic"

The purpose of this study is to determine the safety and effectiveness of hydrocortisone ophthalmic ointment compared to placebo in the treatment of Allergic Conjunctivitis.

The INVIGORATE 2 Trial: A single-center, randomized, double-masked, crossover design, vehicle-controlled, Phase 3 clinical trial to assess the efficacy and safety of reproxalap ophthalmic solution (0.25%) compared to vehicle in subjects with seasonal allergic conjunctivitis using the environmental exposure chamber (EEC).

The trial is a phase II, randomised, parallel-group, double-blind, placebo-controlled multi-site trial conducted in Canada. Before the start of treatment, the subjects will undergo baseline birch and oak Environmental Exposure Chamber sessions. The treatment duration is 24 weeks. The subjects will undergo birch Environmental Exposure Chamber sessions after 8, 16 and 24 weeks of treatment and an oak Environmental Exposure Chamber session after 24 weeks of treatment.

The purpose of this study is to determine the changes of quality of life of patients with allergic rhinoconjunctivitis treated with standard medications plus Dialyzable Leukocyte Extracts (DLE). All patients will receive DLE in combination with current guide lines-suggested standard medication.

This is a randomized, parallel, single center, double masked, vehicle controlled study. The purpose of this study is to determine the activity and safety of NS2 in patients with grass, tree or ragweed-pollen induced seasonal allergic conjunctivitis . Subjects will be randomized 1:1 to receive multiple doses of NS2 Ophthalmic Drops (0.5%) or NS2 Ophthalmic Drops Vehicle (0.0%). Free aldehydes are thought to be related to inflammatory conditions such as allergic conjunctivitis. NS2, a small molecule aldehyde trap, is being evaluated to determine whether it may decrease inflammation by lowering aldehyde levels.

A Single-Center Evaluation of the Anti-Inflammatory Effects of Lastacaft ® as Measured by In-Vivo Confocal Microscopy

To evaluate the efficacy and safety of 0.1% tacrolimus combined with loteprednol etabonate 0.5%/tobramycin 0.3% (LE/T) in vernal keratoconjunctivitis (VKC) patients resistant to conventional treatment. This prospective 6-mouth period study aims to include 20 severe VKC patients who were not responding to conventional treatments. All the patients will be treated with 0.1% tacrolimus suspension two times daily, LE/T eye drops four times daily for 1 month. Additionally, 0.1% olopatadine two times daily and preservative-free artificial tears four times daily will be used. After the first month, LE/T will be stopped, with other treatments continued for the last 5 months. Visual acuity and intraocular pressure (IOP) will be measured at enrollment and 1, 2, 3 and 6 months after treatment. Besides, 6 subjective symptoms and 6 clinical signs will be graded at each visit based on a 4-point scale. The primary endpoints are the change in symptoms and objective signs. Treatment failure will be recorded if extra corticosteroids were required.

The INVIGORATE Trial: A Randomized, Double-masked, Crossover Design, Phase 3 Clinical Trial to Assess the Efficacy and Safety of Subjects With Seasonal Allergic Conjunctivitis.

To evaluate the efficacy of Bilastine Ophthalmic Solution (0.2%,0.4%,0.6%) compared to vehicle for the treatment of the signs and symptoms of allergic conjunctivitis

The present study will be carried out to evaluate the antiallergic efficacy of Bepotastine besilate 1.5% free of preservatives versus standard treatment with 0.2% Olopatadine hydrochloride with 0.1% benzalkonium chloride as preservative in adult patients diagnosed with allergic conjunctivitis. The antiallergic efficacy will be evaluated by the reduction of ocular signs and symptoms and by the resolution of non-ocular symptoms (rhinorrhea, congestion, and nasal pruritus), as well as the effect of the preservative and its relationship with the cytotoxicity of the ocular surface. Also will evaluate the safety of both products.
