This study will describe safety of dupilumab in adult participants with atopic dermatitis. It will also look at the improvement of atopic dermatitis signs and symptoms in these participants.
The maximum study duration would be 32 weeks which includes the below:
Visit frequency: The visit frequency will be every 4 weeks during the 16 weeks treatment duration and then 12 weeks after the last dose of the study treatment. Total number of visits will be 7.

Exclusion Criteria:
The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

Percentage of participants who Experienced Treatment-Emergent Adverse Events (TEAEs)
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
Time frame: Up to Week 16
Proportion of Participants Reaching 75% Reduction from Baseline in Eczema Area and Severity Index (EASI) score (EASI-75)
The final EASI score is the summation of the 4 regional scores, ranging from 0 to 72. A score of 0 indicates clear or no eczema, 0.1 to 1.0 indicates almost clear, 1.1 to 7 indicates mild disease, 7.1 to 21 indicates moderate disease, 21.1 to 50 indicates severe disease, and greater than 51 indicates very severe disease.
Time frame: Week 16
Proportion of Participants with more than equal to (≥) 4-point Reduction in Weekly Average of Daily Pruritus-Numerical Rating Scale (Pruritus NRS)
The Peak Pruritus NRS is a single self-reported item designed to measure peak pruritus, or 'worst' itch, over the previous 24 h based on the following question: 'On a scale of 0 to 10, with 0 being "no itch" and 10 being "worst itch imaginable", how would you rate your itch at the worst moment during the previous 24 hours?'. Proportion of participants with ≥4-point reduction in weekly average of daily Pruritus NRS from baseline in participants with baseline weekly average of daily Pruritus-NRS ≥4 will be reported.
Time frame: Up to Week 16
Change from Baseline in Body Surface Area (BSA) Affected by Atopic Dermatitis
The BSA affected by AD will be assessed for each major section with the rules of 9 : head and neck \[9 percent\], anterior trunk \[18 percent\], back \[18 percent\], upper limbs \[18 percent\], lower limbs \[36 percent\], and genitals \[1 percent\].
Time frame: Baseline to up to Week 16
Percentage of Participants who Experienced TEAE
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
Time frame: Up to 32 Weeks
