Brief Summary:
Sirukumab is a fully human anti interleukin (IL)-6 immunoglobulin G1-kappa monoclonal antibody (MAb) which is in development for the treatment of rheumatoid arthritis (RA). The continuing unmet need in subjects with asthma refractory to corticosteroid therapy and increased understanding of asthma pathogenesis have stimulated the development of targeted biologics based on predictive biomarkers. The majority of approaches to date have targeted T Helper 2 (Th2) cytokines or their downstream effects. Targeting IL-6 in severe asthma represents an unprecedented approach that has potential to address non-Th2 drivers of severe asthma. This multicenter, randomized, double-blind (sponsor-unblind), placebo-controlled, parallel group study will investigate the efficacy of sirukumab compared to placebo in subjects having uncontrolled severe asthma despite use of high dose inhaled corticosteroid (ICS) in combination with long-acting Beta-agonist (LABA). The study will employ a variable treatment period for individual subjects. Dosing will continue every 4 weeks until week 44 (inclusive), or until 24 weeks after the final subject has been randomized, whichever the sooner. Upon receiving the final dose of study medicine or placebo, subjects will enter a 16 week Follow Up period. Overall, the duration of participation for subjects who complete the full 44-week treatment period and Follow Up period may be up to 64 weeks. Approximately 175 subjects will be randomized such that 140 evaluable subjects complete the study.

Primary Outcome Measures :
  1. Change from Baseline in Asthma Control Questionnaire-7 (ACQ-7) at Week 24 [ Time Frame: Baseline and Week 24 ]
    The ACQ-7 is a seven-item questionnaire that is a measure of a subject's asthma control. Six of the questions will be self-completed by the subject, recalling over the previous 7 days. The six questions enquire about the frequency and/or severity of symptoms (nocturnal awakening, activity limitation, shortness of breath and wheeze), and rescue bronchodilator use. The response options for all these questions consist of a zero (no impairment/limitation) to six (total impairment/ limitation) scale. The final question is a rating of forced expiratory volume in 1 second FEV1% predicted. The questions are equally weighted and the ACQ score is the mean of the 7 questions and therefore between 0 (totally controlled) and 6 (severely uncontrolled). Baseline value is the value obtained at Day 1 before administration of investigational product (IP). Change from baseline in ACQ-7 score will be analysed using a Bayesian repeated measures model.


Secondary Outcome Measures :
  1. Safety as assessed by number of subjects with adverse events (AE) and serious adverse events (SAE) [ Time Frame: Up to 60 Weeks ]
    AE is any untoward medical occurrence in a subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE is any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect or any other situation according to medical or scientific judgement.

  2. Safety as assessed by body temperature [ Time Frame: Up to 60 Weeks ]
    Body temperature will be measured in semi-supine position after 5 minutes rest.

  3. Safety as assessed by systolic and diastolic blood pressure [ Time Frame: Up to 60 Weeks ]
    Blood pressure will be measured in semi-supine position after 5 minutes rest.

  4. Safety as assessed by pulse rate [ Time Frame: Up to 60 Weeks ]
    Pulse rate will be measured in semi-supine position after 5 minutes rest.

  5. Safety as assessed by electrocardiogram (ECG) [ Time Frame: Up to 60 Weeks ]
    Centralized 12-lead ECG will be performed in triplicate at baseline and singly thereafter. ECG will also be performed when clinically indicated. ECG measurements will be made after the subject has rested in the supine position for 5 minutes. The ECG will be obtained after the vital signs assessments but before lung function testing followed by other study procedures. Collection shortly after a meal or during sleep will be avoided since QT prolongation can occur at these times.

  6. Safety as assessed by number of subjects with abnormal hematology parameters [ Time Frame: Up to 48 Weeks ]
    Hematology will include hemoglobin, hematocrit, red blood cells (RBC) count, white blood cells (WBC) count, absolute neutrophils, neutrophils segmented percentage with differential, neutrophils bands percentage, basophils percentage, eosinophils percentage, absolute eosinophils, lymphocytes percentage, monocytes percentage, platelet count.

  7. Safety assessed by serum chemistry [ Time Frame: Up to 48 Weeks ]
    Serum chemistry will include potassium, chloride, sodium, calcium, blood Urea nitrogen (BUN), creatinine, glucose, aspartate transaminase (SGOT), alanine transaminase (SGPT), alkaline phosphatise, phosphate, albumin, total protein, direct, indirect and total bilirubin.

  8. Safety assessed by lipid profile [ Time Frame: Up to 48 Weeks ]
    Lipid profile will include total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides.

  9. Change from baseline in ACQ-7 during the treatment period [ Time Frame: Baseline and Up to 48 Weeks ]
    The ACQ-7 is a seven-item questionnaire that is as a measure of a subject's asthma control.

  10. Change from baseline in ACQ-5 during the treatment period [ Time Frame: Baseline and Up to 48 Weeks ]
    The ACQ-5 is a five-item questionnaire that is as a measure of a subject's asthma control. The five ACQ-5 questions are scored on a 7-point scale (0 = good control, 7 = poor control), and the overall score is the mean of the five responses. Baseline value is the value obtained at Day 1 before administration of investigational product (IP). Change from baseline in ACQ-5 score will be analysed using a Bayesian repeated measures model.

  11. Number of subjects who achieve an ACQ-7 response [ Time Frame: Up to 48 Weeks ]
    The ACQ-7 is a seven-item questionnaire that is as a measure of a subject's asthma control.

  12. Change from baseline in pre-bronchodilator FEV1 during the treatment period [ Time Frame: Baseline and Up to 48 Weeks ]
    FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Baseline value is the value obtained at Day 1 before administration of IP. Change from Baseline is the difference between the value at Indicated visit and value at Baseline.

  13. Change from baseline in average morning peak expiratory flow rate (PEFR) [ Time Frame: Baseline and Up to 48 Weeks ]
    PEFR is the maximum flow rate generated during a forceful exhalation, starting from full lung inflation. Baseline value is the value obtained at Day 1 before administration of IP. Change from Baseline is the difference between the value at Indicated visit and value at Baseline.

  14. Change from baseline in St. George's Respiratory Questionnaire (SGRQ) [ Time Frame: Baseline and Up to 48 Weeks ]
    The SGRQ comprises 50 questions designed to measure health status (quality of life) in subjects with diseases of airways obstruction. The SGRQ includes a total score and three domain scores: Symptoms, Activity and Impacts (Psycho-social) as well as a total score. A minimum change in score of 4 units is considered to be established as clinically relevant. A one month recall period shall be used for assessment of the SGRQ. Baseline value is the value obtained at Day 1 before administration of IP. Change from Baseline is the difference between the value at Indicated visit and value at Baseline.

  15. Number of subjects who achieve SGRQ response [ Time Frame: Up to 48 Weeks ]
    The SGRQ comprises 50 questions designed to measure health status (quality of life) in subjects with diseases of airways obstruction.

  16. Change from baseline in daily salbutamol/albuterol use [ Time Frame: Baseline and Up to 48 Weeks ]
    Subjects will complete the Asthma Daily Symptom Diary (ADSD), a novel asthma symptom diary and record daily use of rescue medication (salbutamol/albuterol) via an electronic diary. Baseline value is the value obtained at Day 1 before administration of IP. Change from Baseline is the difference between the value at Indicated visit and value at Baseline.

  17. Annualized rate of severe asthma exacerbations during the treatment period [ Time Frame: Baseline and Up to 48 Weeks ]
    Severe asthma exacerbations are defined as worsening of asthma which requires use of systemic corticosteroids and/or hospitalisation and/or Emergency Department (ED) visits.
