E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Evaluation of the efficacy of sodium cromolyn preservative-free ophthalmic solution compared with placebo in the prevention of symptoms of allergic conjunctivitis induced by Conjunctival Allergen Challenge (CAC) (see Appendix II) in patients with a known history of allergic conjunctivitis. This will be assessed through the primary endpoint, which is the itching subject’s assessment by a 5-point scale, 5 minutes after the CAC.
|
|
E.2.2 | Secondary objectives of the trial |
Conjunctival hyperaemia Tearing. Chemosis. Eyelid swelling Ocular global discomfort assessed by the subject using a Visual Analog scale 15 minutes after the study drugs instillation test. Comparison of tolerability of sodium cromolyn and placebo eye drops will be assessed using global assessments by subject) and reporting of Adverse Events, at visit 3. The subjects will stay in the Study Unit up to two (2) hours after each challenge and a phone call will be given to them 24 hours after each challenge to verify their global status.
