Brief Summary:
Severe asthma affects 5-10% of more than 300 million asthmatics. Ten to twenty percent of individuals suffering from asthma do not respond well to current treatment due to the complexity of the different mechanisms underlying asthma pathogenesis, and sometimes due to an insufficient effect of treatment on underlying airway inflammation. Consequently, some asthmatics have poorer quality of life due to: frequent asthma symptoms, regular medical or emergency visits, limitation in their activities of daily living, including exercise. It is believed that the benralizumab can help to reduce airway inflammation and thus improve exercise tolerance in individuals with asthma. The main objective of this study is to determine the effect of benralizumab on exercise-induced bronchoconstriction (EIB) and exercise tolerance in moderate to severe eosinophilic asthmatics, in comparison with baseline values and a placebo treatment.

Condition or disease Intervention/treatment Phase
Asthma, Exercise-Induced Drug: Benralizumab Phase 3

Detailed Description:
Subjects will receive benralizumab every 4 weeks for three doses followed by a fourth dose 8 weeks later. On baseline and after 4, 16 and 20 weeks, subjects will be assess for airway responsiveness to exercise and exercise tolerance.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: This study is a parallel study, double-blind, placebo controlled randomized trial, with a ratio placebo-active drug 1:2.
Masking: Triple (Participant, Care Provider, Investigator)
Masking Description: The study will be conducted under double-blind conditions. Neither the subject nor the investigator and clinical site personnel will know which medication is administered. The medication given will be determined according to a randomization table handled by a collaborating IUCPQ-UL pharmacist. Only the pharmacist responsible for preparing the medication for the randomized patients will have access to information on treatment allocations (unblended). Benralizumab and placebo solutions for injection in an accessorized pre-filled syringe (PFS) will have the same packaging.
Primary Purpose: Treatment
Official Title: The Effect of Benralizumab on Lung Physiology, Exercise-induced Bronchoconstriction and General Health Status: an Exploratory Mechanistic Study
Estimated Study Start Date : December 2017
Estimated Primary Completion Date : December 2019
Estimated Study Completion Date : April 2020

  2. Asthma diagnosis according to current guidelines;
  3. General good health as declared by the investigator;
  4. Respiratory symptoms such as wheeze, shortness of breath, chest tightness or cough during physical activity;
  5. Moderate to severe eosinophilic asthma (Inhaled corticosteroids, 250 mcg/day fluticasone equivalent or more and long acting beta2-agonists, stable for at least one month);
  6. Sufficient adherence to maintenance therapy (from questionnaire and pharmacy reports: adherence to at least 80% of medication prescribed on both);
  7. Baseline blood eosinophil counts of at least 300 cells/ul and/or sputum eosinophil of at least 3%;
  8. Exercise less than 4 hours per week and remain stable through the study;
  9. Presence of EIB: A post-exercise fall in FEV1 of at least 10% from baseline;
  10. Pre-bronchodilator FEV1 at screening of at least 70% of the predicted value;
  11. Women of childbearing potential (WOCBP) must use an effective form of birth control (confirmed by the investigator). Effective forms of birth control include: true sexual abstinence, a vasectomized sexual partner, Implanon, female sterilization by tubal occlusion, any effective intrauterine device/levonorgestrel Intrauterine system, Depo-Provera™ injections, oral contraceptive, and Evra Patch™ or Nuvaring™. WOCBP must agree to use effective method of birth control, as defined above, from enrolment, throughout the study duration and 20 weeks after last dose of study product, and have negative serum pregnancy test result on Visit 1;

    a. Women not of childbearing potential are defined as women who are either permanently sterilized (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), or who are postmenopausal. Women will be considered postmenopausal if they have been amenorrheic for 12 months prior to the planned date of randomization without an alternative medical cause. The following age-specific requirements apply:

  12. Women <50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatment. They also need follicle stimulating hormone (FSH) levels in the postmenopausal range.
