NCT06800274
This randomized, single-blind study aims to compare the efficacy and safety of N-acetyl-aspartyl-glutamate (NAAGA) and azelastine hydrochloride eye drops in patients with allergic conjunctivitis associated with tear film dysfunction. A total of 134 atopic patients with mild-to-moderate tear film dysfunction were included. Participants were randomly assigned to receive either NAAGA (49 mg/mL, four times daily) or azelastine (0.05%, twice daily) for four weeks. The primary endpoint is the change in Ocular Surface Disease Index (OSDI) scores from baseline to week 4. Secondary endpoints include tear osmolarity, Schirmer test results, tear break-up time (TBUT), MMP-9 levels, and corneal staining scores. This study seeks to provide evidence for the tailored management of allergic conjunctivitis and tear film dysfunction.

NCT03861910
Food allergy is a common chronic condition in childhood. Recent studies have suggested that the natural history of food allergy has changed during the last two decades, with an increased prevalence, severity of clinical manifestations, and risk of persistence into later ages. The increased food allergy prevalence in children has an important economic impact, with significant direct costs for the healthcare system and even larger costs for the families of food-allergic patients. In addition, children with food allergies are at increased risk to develop other allergic manifestations later in life. According to a recent study, children with a food allergy are 2 to 4 times more likely to develop other atopic manifestations such as asthma (4.0 times), atopic eczema (2.4 times), and respiratory allergies (3.6 times), compared to children without a food allergy. Cow's milk allergy is among the most common food allergy in early childhood, with an estimated prevalence of 2% to 3%. It has been previously showed that in children with cow milk allergy, an extensively hydrolysed casein formula supplemented with the probiotic Lactobacillus rhamnosus GG induced higher tolerance rates compared to extensively hydrolysed casein formula without Lactobacillus rhamnosus GG and other formulas. These findings were consistent with those of a 1-year follow-up study performed in the US that showed better outcomes using an extensively hydrolysed casein formula+Lactobacillus rhamnosus GG vs. an extensively hydrolysed casein formula or amino acid-based formula for the first-line dietary management of cow milk allergy. In addition it has been recently demonstrated that extensively hydrolysed casein formula + Lactobacillus rhamnosus GG reduces the incidence of other atopic manifestations and hastens the development of oral tolerance in children with IgE-mediated cow milk allergy. The present randomized controlled trial (RCT) was designed to test whether different dietary interventions could influence the occurrence of other atopic manifestations in children with IgE-mediated cow milk allergy.
NCT05234554
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).
NCT06153342
In this prospective Phase 2, single-center, randomized, double-masked, placebo-controlled study, approximately 70 subjects with allergic conjunctivitis will be randomized 1:1 to receive either TL-925 or placebo as topical ophthalmic eye drops administered bilaterally. The study comprises of a screening and treatment period using the conjunctival allergen challenge model to evaluate TL-925 for the treatment of allergic conjunctivitis.
NCT05829499
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. Patients with moderate-to-severe DED may experience a reduced quality of life due to ocular pain, difficulty in performing daily activities, and depression. Traditionally, dry eye syndrome and allergic conjunctivitis are regarded as 2 different diseases. However, recent literature has shown both conditions share similar characteristics, including several of their signs and symptoms (e.g. red, itchy, watery, and burning eyes). On the other hand, red swollen eyelids, burning sensations, ocular irritation, loss of eyelashes and misdirected eyelashes are also common symptoms of Blepharitis, an inflammatory disorder of eyelids affecting all the age and ethnic groups. First-line therapy for treating dry eye symptoms consists of over the counter (OTC) artificial tear drops, gels, ointments, or lubricants. Manufacturers have developed OTC products that appear to mimic the different layers of the tear film in order to maintain ocular hydration. For these reasons, an interventional, non-comparative, Post Marketing Clinical Follow-up (PMCF) study was planned to evaluate the performance and safety of "Xanoftal Next" used to attenuate symptoms of seasonal allergic conjunctivitis, even when associated with dry eye syndrome. 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 "Xanoftal Next" according to 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, the "Xanoftal Next" product will be administered to the enrolled subject. 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.
