You may be eligible if
1. Written informed consent for study participation must be obtained prior to any study related procedures being performed and according to international guidelines and/or applicable European Union (EU) guidelines.
2. Female and male aged 18 to 75 years inclusively at the time of Visit 1
3. Documented current treatment with ICS and LABA for at least 30 days prior to Visit 1. The ICS and LABA can be parts of a combination product or given by separate inhalers. The ICS dose must be greater than or equal to 500 μg/day fluticasone propionate dry powder formulation or equivalent daily. Additional asthma controller medications, eg, oral corticosteroids, long-acting antimuscarinics (LAMAs), LTRAs, theophylline etc. are allowed if they have been used for at least 30 days prior to Visit 1
4. History of at least 2 asthma exacerbations that required treatment with systemic corticosteroids (intramuscular (IM), intravenous (IV), or oral) in the 12 months prior to Visit 1. For patients receiving corticosteroids as a maintenance therapy, the corticosteroid treatment for the exacerbation is defined as a temporary increase of their maintenance dose.
5. Pre-bronchodilator (pre-BD) FEV1 of \< 80% predicted at Visit 2 or Visit 3
6. ACQ-6 score ≥1.5 at Visit 1
7. Evidence of asthma as documented by airway reversibility (FEV1 ≥12% and 200 ml) demonstrated at Visit 1, Visit 2 or Visit 3. For patients entering the body plethysmography sub-study, reversibility must be demonstrated at Visit 1 or at Visit 2 only
8. Peripheral blood eosinophil count of ≥300 cells/μL assessed by central lab at Visit 1
9. Women of childbearing potential (WOCBP) must use an effective form of birth control confirmed by the Investigator. WOCBP must also have negative serum pregnancy test result on Visit 1.
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 agespecific requirements apply:
* Women \<50 years old are considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatment and follicle stimulating hormone (FSH) levels in the postmenopausal range.
* Women ≥50 years old are considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatment.
10. All male patients who are sexually active must agree to use a double barrier method of contraception (condom with spermicide) from the first dose of IP until 16 weeks after their last dose
11. Weight of ≥40 kg
1. At least 1 of the following within 7 days prior to randomization:
* Daytime or nighttime asthma symptoms for 2 or more days;
* Rescue SABA use for 2 or more days;
* Nighttime awakenings due to asthma at least 1 night during the 7-day period
2. ACQ \>0.75 at Visit 4 prior to randomization.
3. A negative urine pregnancy test in WOCBP prior to administration of IP
You may not be if
1. Clinically important pulmonary disease other than asthma (eg, active lung infection, COPD, bronchiectasis, pulmonary fibrosis, cystic fibrosis, hypoventilation syndrome associated with obesity, lung cancer, alpha 1 anti-trypsin deficiency, and primary ciliary dyskinesia) or ever been diagnosed with pulmonary or systemic disease, other than asthma, that are associated with elevated peripheral eosinophil counts (eg, allergic bronchopulmonary aspergillosis/mycosis, Churg-Strauss syndrome, hypereosinophilic syndrome)
2. Life-threatening asthma defined as episodes requiring intubation associated with hypercapnia, respiratory arrest, hypoxic seizures, or asthma related syncopal episodes within the 12 months prior to Visit 1.
3. Acute upper or lower respiratory infections requiring antibiotics or antiviral medication within 30 days prior to the date informed consent is obtained or during the screening/run-in period
4. An upper respiratory tract infection or an asthma exacerbation that required treatment with systemic corticosteroids or an increase in regular maintenance dose of OCS during the screening/run-in period prior to randomization Visit 4
5. Any disorder, including, but not limited to, cardiovascular, gastrointestinal, hepatic, renal, neurological, musculoskeletal, infectious, endocrine, metabolic, haematological, psychiatric, or major physical impairment that is not stable in the opinion of the Investigator and could:
* Affect the safety of the patient throughout the study
* Influence the findings of the studies or their interpretations
* Impede the patient's ability to complete the entire duration of study
6. Known history of allergy or reaction to any component of the investigational product formulation
7. History of anaphylaxis to any biologic therapy
8. History of Guillain-Barré syndrome
9. A helminth parasitic infection diagnosed within 24 weeks prior to the date informed consent is obtained that has not been treated with, or has failed to respond to standard of care therapy
10. Any clinically significant abnormal findings in physical examination, vital signs, hematology, clinical chemistry, or urinalysis during screening period, which in the opinion of the Investigator, may put the patient at risk because of his/her participation in the study, or may influence the results of the study, or the patient's ability to complete entire duration of the study
11. Any clinically significant cardiac disease or any electrocardiogram (ECG) abnormality obtained during the screening/run-in period, which in the opinion of the Investigator may put the patient at risk or interfere with study assessments
12. History of alcohol or drug abuse within 12 months prior to the date informed consent is obtained
13. Positive hepatitis B surface antigen, or hepatitis C virus antibody serology, or a positive medical history for hepatitis B or C. Patients with a history of hepatitis B vaccination without history of hepatitis B are allowed to enroll
14. A history of known immunodeficiency disorder including a positive human immunodeficiency virus (HIV) test
15. Current smokers or former smokers with a smoking history of ≥10 pack years. A former smoker is defined as a patient who quit smoking at least 6 months prior to Visit 1
16. Current malignancy, or history of malignancy, except for:
* Patients who have had basal cell carcinoma, localized squamous cell carcinoma of the skin or in situ carcinoma of the cervix are eligible provided that the patient is in remission and curative therapy was completed at least 12 months prior to the date informed consent was obtained.
* Patients who have had other malignancies are eligible provided that the patient is in remission and curative therapy was completed at least 5 years prior to the date informed consent was obtained.
17. Use of immunosuppressive medication (including but not limited to: oral corticosteroids \[for reasons other than asthma\], methotrexate, troleandomycin, cyclosporine, azathioprine, intramuscular long-acting depot corticosteroids or any experimental anti-inflammatory therapy) within 3 months prior to the date informed consent
