| Scientific title | A Colateral, Double-Masked, Randomized Study to Evaluate Preservative-Free Levocabastine 0.05% Ophthalmic Solution When Compared to Preserved Levocabastin 0.05% Ophthalmic Suspension or Preservative-Free Levocabastine Ophthalmic Solution Vehicle During Allergen Challenge |
| Study acronym | Levocabastine |
| Study objectives | Evaluation of efficacy and safety of Prerservative-free Levocabastine ophthalmic solution compared to Preserved Levocabastine ophthalmic suspension and Preservative-free Levocabastine ophthalmic solution vehicle in prevention of allergic conjunctivitis induced by ocular allergen challenge |
| Ethics approval(s) | Approval received from the local ethics committee (Comité de Protection des Personnes CPP Ile de France III) on the 31st of July 2007 (Ref: CPP Dossier No 2445) |
| Health condition(s) or problem(s) studied | Allergic Conjunctivitis |
| Intervention | 1. Preservative-free Levocabastine 0.05% ophthalmic solution (formula LCM-1218) 2. Preserved Levocabastine 0.05% ophthalmic suspension (Levophta, formula LCM-1215) 3. Preservative-free Levocabastine ophthalmic solution vehicle (formula LCM-1228) 3/4 of patients will receive (1) in one eye and (2) in the second eye 1/4 of patients will receive (3) in one eye and (2) in the second eye One drop of the applicable medication/placebo will be administered by study personnel at 10 min (Visit 3) or 4 hours (Visit 4) prior to CPT. No further follow up. |
