Filter by:The purpose of this study is to evaluate the efficacy and safety of four doses of PRO-118 ophthalmic solution ophthalmic solution compared with placebo, for the treatment of seasonal (SAC) and perennial (PAC) allergic conjunctivitis.
This study will gather information on allergic rhinoconjunctivitis from surveys completed by adults and children.
The purpose of this study is to evaluate the effectiveness of the modified Conjunctival Allergen Challenge (CAC) and observe how the produced allergic inflammation reacts to treatment with a proven ocular anti-inflammatory medication, Prednisolone, assessed by the following measures: - Ocular itching - Conjunctival redness
The investigators are conducting this study because the patient have an eye infection which is called adenoviral conjunctivitis, and is the most common cause of "pink eye". There is currently no treatment for this condition. However, the researchers associated with this study want to understand if using a product called Zirgan, which is a topical ointment that is already FDA-approved for other types of eye infections, will help with the type of infection that the patient currently have. Zirgan is not FDA-approved to treat your type of eye infection. Your participation in this study is expected to last 21 days but the patient will only apply the topical ointment for 14 of those days. During the study, the patient will be asked to come into this clinic 8 times. The purpose of this study is to determine whether topical Zirgan can reduce days that the patient suffers from the eye infection, and also to see if it can prevent the infection from spreading to your second eye and to also see if it can prevent the spreading of the infection to people that the patient come in close contact with. Zirgan will be compared to Genteal Gel in this trial. Genteal Gel is a non-prescription eye lubricant gel and is commonly used for treatment of dry eye. The patient will be asked to apply a topical ointment (either Zirgan or Genteal gel 5 times a day for the first 7 days and then 3 times a day for the following 7 days. The patient will be asked to return to the clinic 21 days after the patient starts the study for a final check-up. It is planned that about 80 people with Adenovirus Conjunctivitis will be enrolled in this study between 8-12 sites across the United States. The patient will be assigned to either Zirgan or Genteal gel by chance which is similar to flipping a coin. The study groups will be assigned in a 1:1 ratio. Neither the patient nor the study doctor or study staff will be able to pick which study group The patient is in. The patient will not know and the study doctor or study staff will not know which study group the patient is in. The study doctor or study staff can find out if it is necessary to know for your health. If this happens, the study doctor or study staff may not be able to tell the patient which study group the patient was in until everyone finishes the study.
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.
The purpose of this study is to find out if rBet v1-FV works to relieve Seasonal Allergic Rhinitis symptoms compared to Placebo (an inactive substance that looks like rBet v1-FV and also contains Aluminum Hydroxide but does not contain the experimental drug). rBet v1-FV is a vaccine that works by exposing your immune system to something that resembles birch. This vaccine may help to lessen your allergy symptoms during the natural birch season.
Based on EMA (European Medicines Agency) new guidelines on the clinical development of products for immunotherapy for the treatment of allergic disease the aim of this study was to assess safety and tolerability of three different subcutaneous immunotherapy dose escalations in patients allergic to the pollen of Phleum pratense.
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 was to assess safety and tolerability of 3 different subcutaneous immunotherapy dose escalations in patients allergic to Dermatophagoides pteronyssinus.
Grass pollen and house dust mites (HDM) are the most common allergens causing allergic rhino-conjunctivitis (RC) and/or asthma (A). Subcutaneous allergen specific immunotherapy (SCIT) reduces symptoms and use of medication. The purpose of SABAL is to assess the effect of SCIT on disease severity classifications in terms of number of days affected- and sick days on patients with grass pollen and/or HDM induced disease. These outcome measures will be gathered in one single measure: Quality Adjusted Life Years (QALY)
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.
