Status: Authorised-recruitment may be ongoing or finished

Sex: All

Target Recruitment: 340

Inclusion Criteria

-18 to 70 years of age inclusive with the diagnosis of asthma based on Global Strategy for Asthma Management and Prevention (GINA) 2019 at the time of signing the informed consent
-History of =1 exacerbation (s) in the previous year
-Uncontrolled moderate to severe asthma (ACQ-5 =1.5) at V1 and V2, prior to randomization
-Pre-bronchodilator FEV1 =80% of predicted normal at V1 and V2, prior to randomization
-Exhibit bronchodilator reversibility (=12% and 200 mL improvement in FEV1 post SABA administration) during screening, prior to randomization
-Blood eosinophil =300 cells /µL and FeNO =25 ppb during screening, prior to randomization
-Existing treatment with medium to high dose ICS in combination with a second controller (e.g. LABA, LTRA) ± a third controller. The dose regimen should be stable =1 month prior V1 and during screening.

Exclusion Criteria

-Current smoker (cigarette or e-cigarette) or cessation of smoking within 1 year prior randomization
-Previous smoker with a smoking history >10 pack-years
-Known hypersensitivity to dupilumab or any of its excipients
-Asthma exacerbation during the screening, prior to randomization
-Current acute bronchospasm or status asthmaticus
-Diagnosed pulmonary (other than asthma) or systemic disease associated with elevated peripheral eosinophil counts
-History or clinical evidence of chronic obstructive pulmonary disease (COPD) including Asthma-COPD Overlap Syndrome (ACOS) or any other significant lung disease (eg, lung fibrosis, sarcoidosis, interstitial lung disease, pulmonary hypertension, bronchiectasis, Churg-Strauss Syndrome, etc)
- Active tuberculosis, latent untreated tuberculosis or a history of incompletely treated tuberculosis or non-tuberculous mycobacterial infection unless it is well documented by a specialist that the patient has been adequately treated and the treatment with a biologic agent can be initiated, in the medical judgment of the Investigator and/or infectious disease specialist. Tuberculosis testing would only be performed on a country by country basis according to the routine clinical practice and the local guidelines, if required by regulatory authorities or ethics committees.
-History of or current evidence of clinically significant disease in any non-respiratory system (e.g. cardiovascular, nervous system, gastrointestinal, endocrinological, rheumatological, dermatological), which, in the judgment of the Investigator, could interfere with the study or require treatment that might interfere with the study
-Current evidence of clinically significant oncological disease, which in the opinion of the investigator may interfere with the objectives of the study or put the subject at undue risk
-Participants with any of the following results at Visit (V) 1:
-Positive (or indeterminate) hepatitis B surface antigen (HBs Ag) or
-Positive Hepatitis B IgM core antibody (IgM HBc Ab) or
-Positive total hepatitis B core antibody (total HBc Ab) confirmed by positive HBV DNA or
-Positive hepatitis C antibody (HCV Ab) confirmed by positive HCV RNA
-History of human immunodeficiency virus (HIV) infection or positive HIV serology at V 1
-Any biologic therapy (including experimental treatments and dupilumab) or any other biologic therapy/immunosuppressant within 3 months prior to V1
-Treatment with live (attenuated) vaccine within 12 weeks before V1
-Chronic treatment with oral corticosteroids (OCS) for more than 2 weeks before V1
-Enrolled in other ongoing studies regardless of the investigational product
-Treatment with an investigational drug within 8 weeks or within 5 half-lives (if known), whichever is longer, prior to V1
-Suspected or high risk of parasitic infection (helminthic infection), unless clinical and (if necessary) laboratory assessments have ruled out active infection prior to randomization
-Females who are lactating, breastfeeding, or who are pregnant
-Individuals accommodated in an institution because of regulatory or legal order; prisoners or subjects who are legally institutionalized
-Patients are dependent on the Sponsor or Investigator (in conjunction with Section 1.61 of the ICH GCP Ordinance E6)
-Patients are employees of the clinical study site or other individuals directly involved in the conduct of the study, or immediate family members of such individuals
-Sensitivity to any of the study interven
