A Phase 4, Randomized, Double-blind, Placebo-controlled, Multicenter, Parallel-group Study of the Effect of Dupilumab on Sleep Disturbance in Patients With Uncontrolled Persistent Asthma

Current smoker

Former smoker for 10 years with a smoking history of \>10 pack-years

Severe asthma exacerbation during screening, prior to randomization

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)

History of or current evidence of clinically significant non-respiratory diseases that in the opinion of the investigator may interfere with the aims of the study or put the participant at undue risk

Active tuberculosis (TB) or non-tuberculous mycobacterial infection, or a history of incompletely treated TB will be excluded unless it is well documented by a specialist that the participant has been adequately treated and can now start treatment with a biologic agent, in the medical judgment of the Investigator and/or infectious disease specialist. Tuberculosis testing would be performed on a country by country basis, according to local guidelines if required by Regulatory Authorities or ethics boards

Diagnosed active endoparasitic infection; suspected or high risk of endoparasitic infection, unless clinical and (if necessary) laboratory assessment have ruled out active infection before randomization

History of human immunodeficiency (HIV) infection or positive HIV test at screening Visit 1

Active chronic or acute infection requiring treatment with systemic antibiotics, antivirals, antiprotozoals, or antifungals within 2 weeks before screening

Known or suspected immunodeficiency including history of invasive opportunistic infections, despite infection resolution

Current evidence of clinically significant oncological disease

History of systemic hypersensitivity or anaphylaxis to any biologic therapy

Severe uncontrolled depression

Sleep disturbances not related to asthma, including sleep apnea, hypersomnia, or insomnia secondary to chronic pain, atopic dermatitis (AD), COPD or other conditions

Participant who works night shift (ie, any work between 8 pm and 6 am)

Erratic sleep habits, as determined by the Investigator

Restless leg syndrome or periodic limb movement disorder

Chronic treatment with oral corticosteroid (OCS) for more than 2 weeks before screening Visit 1

Participant taking sedative, anxiolytic, or hypnotic treatments, including melatonin, within 3 months before randomization

Participant taking systemic sedative antihistamines (excluding newer generations of antihistamines) or theophylline

Current treatment with antidepressants, lipophilic beta blockers, clonidine, opioids, or other medications known to interfere with sleep and may confound the study assessments, as determined by the Investigator

Participant who has taken biologic therapy (including dupilumab)/systemic immunosuppressant to treat inflammatory disease or autoimmune disease (eg, rheumatoid arthritis, inflammatory bowel disease, primary biliary cirrhosis, systemic lupus erythematosus, multiple sclerosis, etc) within 2 months or 5 half-lives before screening Visit 1, whichever is longer

Treatment with live (attenuated) vaccine within 4 weeks before screening Visit 1

* NOTE: For participants who have vaccination with live, attenuated vaccines planned during the course of the study (based on national vaccination schedule/local guidelines), it will be determined, after consultation with a physician, whether the administration of vaccine can be postponed until after the end of the study, (i.e. after the 12 week follow-up period off-treatment or until the participant switches to commercialized dupilumab or other biologic product, whichever comes first), or preponed to before the start of the study without compromising the health of the participant:

* Participant for whom administration of live (attenuated) vaccine can be safely postponed would be eligible to enroll into the study

* Participant who have their vaccination preponed can enroll in the study only after a gap of 4 weeks following administration of the vaccine
