This study has been completed.

First received: March 8, 2012
Last updated: April 29, 2013
Last verified: April 2013

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 Intervention Phase
Asthma Drug: ONO-6950 Drug: Placebo Drug: Montelukast Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Double-blind, Placebo-controlled, Three-way Crossover Study to Compare the Safety and Efficacy of 8 Days of Therapy With ONO-6950 Versus Placebo and Montelukast (Singulair®) on Asthmatic Responses and Airway Hypersensitivity Following Allergen Challenge in Patients With Asthma

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

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

Enrollment: 25
Study Start Date: June 2012
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Experimental 200 mg dose Drug: ONO-6950
200 mg QD for 8 days
Active Comparator: Active Comparator Drug: Montelukast
10 mg Montelukast QD for 8 days
Placebo Comparator: Placebo Comparator Drug: Placebo
Placebo to match ONO-6950 tablets or over-encapsulated Montelukast tablets dosed in a similar manner

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.

Ages Eligible for Study:   18 Years to 60 Years   (Adult)
Sexes Eligible for Study:   All
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
  • Screening allergen challenge demonstrates that the patient experiences both an early and late asthmatic response
  • Sensitivity to methacholine resulting in a ≥ 20% fall in FEV1 (PC20 methacholine)
  • Non-smokers with free from the usage of nicotine-containing products at least for a year prior to screening

Exclusion Criteria:

  • Previous history of life-threatening asthma, respiratory tract infection and/or exacerbation of asthma within 6 weeks prior to the first screening visit
  • Past or present disorders and diseases including, but are not limited to, cardiovascular, malignancy, hepatic, renal, hematological, neurological, psychiatric, endocrine, or pulmonary other than asthma
  • Significant safety laboratory, ECG, or vital sign abnormalities that would place the patient at undue disk during the study procedures
  • History of clinically significant multiple drug or food allergy
