Active clinical trials for "Conjunctivitis"

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).

Viral conjunctivitis causes redness, tearing, swelling, and irritation of the eyes that typically lasts from 1 to 3 weeks. Current management of this condition focuses on supportive care while the viral infection completes its course and resolves. However, many patients still experience substantial discomfort despite standard treatments, and, given the disproportionate morbidity and potential economic impact associated with an outbreak of infective conjunctivitis, a therapeutic agent that reduces clinical symptoms of and minimizes shedding of infectious virus would be desirable. Povidone-iodine is an antiseptic extensively used in preparation for general surgery, ophthalmic purposes, and laboratory disinfection. Dilute povidone-iodine solutions inhibit numerous viruses, bacteria, fungi, and some other parasites. Low cost, effectiveness, and lack of microbial resistance make povidone-iodine an appealing drug to treat ocular infections, especially in developing countries. Previously studies showed that povidone-iodine is a potential option to reduce contagiousness in cases of adenoviral infections. Dexamethasone 0.1%/povidone-iodine 0.4% it is a mixture containing a steroid and antiseptic is promising as a suitable therapeutic agent for the treatment of EKC. A small, prospective, open-label, single-armed clinical trial of dexamethasone 0.1%/povidone-iodine 0.4% administration in humans with symptoms of acute conjunctivitis who tested positive for adenoviral antigen was therapeutically successful. In other study, dexamethasone 0.1%/povidone-iodine 0.4% combination markedly lowered the viral concentration and improved the manifestations of the disease. So, the favorable human data in combination with in vivo results provide a strong impetus for a human phase III clinical trial to test the efficacy of this drug in a larger group and also to evaluate complete safety to properly establish the therapeutic benefit versus adverse effect for these reasons, the investigators chose to study the efficacy of dexamethasone 0.1%/povidone-iodine 0.4% in treating the symptoms and signs of viral conjunctivitis. The administration of dexamethasone 0.1%/povidone-iodine 0.4% can be a secure, tolerable and affective treatment to inflammatory and infective component of acute viral conjunctivitis.

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.

The purpose of this study is to evaluate the clinical and microbiological efficacy and safety of NVC-422 compared to vehicle for adenoviral conjunctivitis. Adults and children one year of age and older with diagnosis of adenoviral conjunctivitis in at least one eye based upon a positive adenovirus test result using the Aden-Detactor Plus kit (Rapid Pathogen Screening, Inc). Subjects will be randomly assigned to receive either NVC-422 or Vehicle.

Based on EMA (European Medicines Agency) new guidelines on the clinical development of products for immunotherapy for the treatment of allergic diseases the aim of this study is to establish a dose-response relationship for clinical efficacy of Phleum pratense pollen extract subcutaneous vaccine.

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.

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

The purpose of the study is to demonstrate safety and efficacy of Olopatadine 0.2% compared to its vehicle in Japanese subjects in the treatment of acute allergen-mediated conjunctivitis using the conjunctival allergen challenge (CAC) test.

Due to the worldwide increasing prevalence of the allergic rhinoconjunctivitis, new therapeutical strategies are needed. The symptomatic treatment with topical and systemic antihistamines and corticosteroids are often insufficient. E.coli Nissle 1917 has immunomodulatory capacities and reveals less side effects. E.coli Nissle 1917 has no sedative properties and exhibits no hepatotoxic qualities. Thus, E.coli Nissle 1917 represents a new relevant therapeutical agent.

The purpose of this study is to assess the safety and efficacy of AL-38583 in the treatment of the signs of inflammation associated with allergic conjunctivitis.
