Brief Summary:

The primary objectives are

  • to determine the effect of ONO-6950 200 mg QD versus placebo administered for 8 days on early asthmatic response (EAR) and late asthmatic response (LAR) induced by inhaled allergen
  • to determine the safety and tolerability of ONO-6950 200 mg QD administered for 8 days in patients with asthma

The secondary objectives are:

  • to compare the effect of ONO-6950 versus montelukast on the % decrease of FEV1 following allergen exposure, and
  • to determine the effect of ONO-6950 versus placebo and montelukast on allergen-induced airway hyperresponsiveness (AHR) as measured by methacholine challenge

Condition or disease Intervention/treatment Phase
Asthma Drug: ONO-6950 Drug: Placebo Drug: Montelukast Phase 2

Detailed Description:
The study will examine if ONO-6950 could alleviate EAR and LAR caused by an allergen challenge in subjects with asthma. Patients will be required to have EAR and LAR after standardized allergen challenges during the screening. Eligible patients will complete a randomized, double-blind, three-way crossover study. During each of three evaluation periods, patients will be administered either 200 mg ONO-6950, 10 mg Montelukast, or placebo for 8 days. Each evaluation period will occur over 8 days and will include various assessments following allergen challenge and methacholine challenge. The study does not require an overnight stay at the clinical research center.

Primary Outcome Measures :
  1. Late Asthmatic Response (3-7 hours after allergen challenge) as measured by the AUC in FEV1 [ Time Frame: Day 7 ]
  2. Early Asthmatic Response as measured by the AUC in FEV1 [ Time Frame: Day 7 ]
  3. Late Asthmatic Response as measured by the Maximum Fall in FEV1 [ Time Frame: Day 7 ]
  4. Early Asthmatic Response as measured by the Maximum Fall in FEV1 [ Time Frame: Day 7 ]

Secondary Outcome Measures :
  1. Differences in PC20 pre-post treatment as measured by methacholine challenge [ Time Frame: Day 6 ]
  2. Differences in PC20 pre-post allergen challenge as measured by methacholine challenge [ Time Frame: Day 8 ]

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients of both genders, between 18 to 60 years of age, with bronchial asthma symptoms for at least 6 months
  • Patients with FEV1 ≥ 70% of predicted after withholding short-acting β agonists for at least 8 hours prior to testing
