NCT00357019	Study of the Clinical and Biological Efficacity of NAAXIA SINE® in Vernal Keratoconjunctivitis	Completed	Laboratoires Thea	Phase 4	To assess the clinical and biological efficacity of preservative free NAAGA eyes drops in vernal keratoconjunctivitis
NCT01949051	A Study to Assess Intranasal Repeat Dose Effect of Levocabastine in the Subjects With Allergic Rhinitis	Completed	GlaxoSmithKline	Phase 2	This study will be a randomized, double blind, placebo controlled, 3-way cross over design in allergic rhinitis subjects. Subjects will receive repeat doses of intra-nasal levocabastine for 7 days in each period and the duration of the study will be about 13 weeks. An Environmental Exposure Chamber (EEC) will be used in this study. The primary objective of the study is to investigate the non-inferiority effect of 7 days treatment with levocabastine on nasal symptoms elicited by an EEC when administered once daily (QD) compared with twice daily (BID). Also study will be conducted to investigate the superiority of effect of 7 days treatment with levocabastine (QD and BID) on nasal symptoms elicited by an EEC in subjects compared to placebo.
NCT01957202	A Proof of Concept Study to Assess Effect of Fluticasone Furoate (FF)/Levocabastine Fixed Dose Combination (FDC) Compared With Levocabastine and FF Alone in Subjects With Allergic Rhinitis (AR)	Completed	GlaxoSmithKline	Phase 2	This study will be a randomised, double blind, placebo controlled, 3-way, incomplete block crossover study to evaluate the effect of single and repeat doses of levocabastine, FF, placebo and a FDC of FF/levocabastine administration in AR subjects. The total expected study duration for each individual participating in the study will be a maximum of up to 20 weeks (including the screening and follow-up). This will be a three period study and subjects will be assigned to a sequence of three treatments. There will be a wash-out period of 14-28 days between two treatment periods. The rational for this study is to demonstrate proof of concept with the FDC of FF and levocabastine compared with each of the components administered alone.
NCT01962467	A Relative Bioavailability Study of Fluticasone Furoate and Levocabastine	Completed	GlaxoSmithKline	Phase 1	This is an open label, randomized, 3-way cross-over, and repeat administration study in healthy male and female subjects. The purpose of the study is to determine the relative bioavailability of Fluticasone Furoate (FF) and Levocabastine (LEV), when each is administered alone and as FF/LEV Fixed Dose Combination (FDC).This study consists of Part A (in which 30 subjects including 12 Korean subjects will be enrolled) and Part B (in which 18 subjects will be enrolled). Each part will consist of three treatment periods separated by a minimum washout period of 14 days. In each treatment period, subjects will receive seven daily doses of one of the 3 treatments: FF, LEV or FF/LEV FDC, via an intranasal spray according to one of the 6 possible randomization sequences. The study will use an adaptive design with an interim review following Part A to confirm whether Part B is required.
NCT02440243	Grass Pollen Subcutaneous Immunotherapy in Elderly Patients	Completed	Medical University of Silesia	Phase 4	Background There is limited evidence indicating that specific immunotherapy in elderly patients is safe and effective. This study was performed to evaluate the safety and efficacy of specific subcutaneous immunotherapy (SCIT) against grass pollen allergens in patients over 60 years of age with seasonal allergic rhinitis (SAR) and a confirmed allergy to grass pollen. Objective This study assessed the safety and efficacy of SCIT for grass pollen allergens in elderly patients with SAR. Methods This study included 62 60- to 75-year-old patients with SAR and grass pollen allergy confirmed using a skin prick test, nasal provocation, and serum IgE measurement. The patients were individually randomized to the active or placebo groups using a double-blinded method. There were 33 subjects in the SCIT group (Purethal, Grass pollen, HAL Allergy B.V, Leiden, Netherlands) and 29 subjects in the placebo group monitored for three years. The patients were required to record each use of anti-allergy medication in a diary and use a visual graphic scale. The main outcome measure was the area under the curve (AUC) for the combined symptom and medication score (SMS).
