NCT ID: NCT01225549

Last Updated: 2015-04-02

Results Overview

LAR was assessed on Day 6 as minimum percentage of FEV1 over 3 to 7 hours based on the analysis of the minimum percentage of FEV1 remaining over 3 to 7 hours post allergen challenge (post AC) compared to pre allergen challenge (pre AC) FEV1

Recruitment status

COMPLETED

Study phase

PHASE2

Target enrollment

Participant Flow

Patients were enrolled from 4 centres in the AllerGen CIC group in Canada.

Total 27 patients enrolled, 20 (74.1%) patients were randomised to receive a treatment sequence consisting of 4 different treatment in random order. From 20 randomised patients, 18 (90%) patients completed the study and 2 (10%) patients were withdrawn from the study due to consumption of disallowed medication
