Primary Outcome Measures:
  • Late Asthmatic response measured by forced expiratory volume in 1 second (FEV1) maximum fall in %. [ Time Frame: Repeated assessments pre (within 1 h) and 3 to 7 h after allergen challenge. Allergen Challenge will be performed at screening and on day 6 of treatment in each treatment period. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Early Asthmatic response measured by forced expiratory volume in 1 second (FEV1) maximum fall in %. [ Time Frame: Repeated assessments pre (within 1 h) and up to 3 h after allergen challenge. Allergen Challenge will be performed at screening and on day 6 of treatment in each treatment period. ] [ Designated as safety issue: No ]
  • AUC based EAR(0-3h) [ Time Frame: Repeated assessments pre (within 1 h) and up to 3 h after allergen challenge. Allergen Challenge will be performed at screening and on day 6 of treatment in each treatment period. ] [ Designated as safety issue: No ]
  • AUC based LAR (3-7h) [ Time Frame: Repeated assessments pre (within 1 h) and 3 to 7 h after allergen challenge. Allergen Challenge will be performed at screening and on day 6 of treatment in each treatment period. ] [ Designated as safety issue: No ]
  • Airway hyperresponsiveness to methacholine, PC20 [ Time Frame: 24h pre and 24 h after allergen challenge. Allergen Challenge will be performed at screening and on day 6 of treatment in each treatment period. ] [ Designated as safety issue: No ]
