Eligibility Criteria:
Inclusion Criteria:~1. Written informed consent and any locally required authorisation obtained from the subject prior to performing any protocol-related procedures, including screening evaluations.~2. Age 18 and above.~3. Diagnosis of AD as defined by the Hanifin and Rajka (1980) criteria for AD (34; Appendix 5).~4. Diagnosis of AD for ≥1 year.~5. Subjects who have a recent history (within 1 year before the screening visit) of inadequate response to treatment with topical medications or for whom topical treatments are otherwise medically inadvisable (e.g., due to important side effects or safety risks).~   Inadequate response is defined as failure to achieve and maintain remission or a low disease activity state (comparable to IGA 0=clear to 2=mild) despite treatment with a daily regimen of TCS of medium to higher potency (±TCI as appropriate), applied for at least 28 days or for the maximum duration recommended by the product prescribing information (e.g., 14 days for super potent TCS), whichever is shorter.~   Subjects with documented systemic treatment for AD in the past year are also considered as inadequate responders to topical treatments and are potentially eligible for treatment with tralokinumab after appropriate washout.~   Important side effects or safety risks are those that outweigh the potential treatment benefits and include intolerance to treatment, hypersensitivity reactions, significant skin atrophy, and systemic effects, as assessed by the investigator or by the subject's treating physician.~6. AD involvement of ≥10% body surface area at screening and baseline (visit 3).~7. An EASI score of ≥12 at screening and 16 at baseline.~8. An IGA score of ≥3 at screening and at baseline.~9. A Worst Daily Pruritus numeric rating scale (NRS) average score of ≥4 during the week prior to baseline.~   Worst Daily Pruritus NRS at baseline will be calculated from daily assessments of worst itch severity (Worst Daily Pruritus NRS) during the 7 days immediately preceding randomisation (Day 6 to 0). A minimum of 4 Worst Daily Pruritus NRS scores out of the 7 days is required to calculate the baseline average score. For subjects who do not have at least 4 scores reported during the 7 days immediately preceding the planned randomisation date, randomisation should be postponed until this requirement is met, but without exceeding the 6 weeks maximum duration for screening.~10. Subjects must have applied a stable dose of emollient twice daily (or more, as needed) for at least 14 days before randomisation (refer to exclusion criterion no. 8 for limitations regarding emollients).~11. Women of childbearing potential must use a highly effective\* form of birth control (confirmed by the investigator) throughout the trial and at least for 16 weeks (5 half lives) after last administration of IMP.~    * A highly effective method of birth control is defined as one which results in a low failure rate (less than 1% per year) such as bilateral tubal occlusion, intrauterine device (IUD), intrauterine hormone-releasing system (IUS), combined (oestrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable), sexual abstinence (when this is in line with the preferred and usual life style of the subject), vasectomised partner (given that the subject is monogamous). The subjects must have used the contraceptive method continuously for at least 1 month prior to the pregnancy test at baseline. A female is defined as not being of child-bearing potential if she is postmenopausal (at least 12 months with no menses without an alternative medical cause prior to screening), or surgically sterile (hysterectomy, bilateral salpingectomy or bilateral oophorectomy).~Exclusion Criteria:~1. Concurrent enrolment in another clinical trial where the subject is receiving an IMP.~2. Previous randomisation in tralokinumab trials.~3. Active dermatologic conditions that may confound the diagnosis of AD or would interfere with assessment of treatment, such as scabies, cutaneous lymphoma, or psoriasis.~4.

Use of tanning beds or phototherapy (narrow band ultraviolet B \[NBUVB\], ultraviolet B \[UVB\], ultraviolet A1 \[UVA1\], psoralen + ultraviolet A \[PUVA\]), within 6 weeks prior to randomisation.~6. Treatment with the following medications within 4 weeks prior to randomisation:~   * Systemic immunosuppressive/immunomodulating drugs (e.g. methotrexate, cyclosporine, azathioprine, mycophenolate mofetil, Janus kinase inhibitors etc.).~  * Systemic corticosteroid use (excludes topical, inhaled, or intranasal delivery).~  * Three or more bleach baths during any week within the 4 weeks.~7. Treatment with the following medications within 2 weeks prior to randomisation~   * TCS.~  * TCI.~  * Topical PDE 4 inhibitor.~8. Initiation of treatment of AD with prescription emollients or emollients containing additives such as ceramide, hyaluronic acid, urea, or filaggrin degradation products during the screening period (subjects may continue using stable doses of such emollients if initiated before the screening visit).~9. Receipt of live attenuated vaccines 30 days prior to the date of randomisation and during the trial including the safety follow-up period.~   • Receipt of inactive/killed vaccinations (e.g. inactive influenza) are allowed, provided they are not administered within 5 days before/after any study visit.~10. Receipt of any marketed (i.e. immunoglobulin, anti-IgE) or investigational biologic agent, including dupilumab:~    * Any cell-depleting agents including but not limited to rituximab: within 6 months prior to randomisation, or until lymphocyte count returns to normal, whichever is longer.~   * Other biologics: within 3 months or 5 half-lives, whichever is longer, prior to randomisation.~11. Receipt of any investigational non-biologic agent within 5 half-lives prior to randomisation.~12. Receipt of blood products within 4 weeks prior to screening.~13. Major surgery within 8 weeks prior to screening, or planned in-patient surgery or hospitalisation during the trial period.~14. Known or suspected allergy or reaction to any component of the IMP formulation.~15. History of any active skin infection within 1 week prior to randomisation.~16. History of a clinically significant infection within 4 weeks prior to randomisation which, in the opinion of the investigator or sponsor's medical expert, may compromise the safety of the subject in the trial, interfere with evaluation of the IMP, or reduce the subject's ability to participate in the trial. Clinically significant infections are defined as:~    * a systemic infection.~   * a serious skin infection requiring parenteral (intravenous or intramuscular) antibiotics, antiviral, or antifungal medication.~17. A helminth parasitic infection within 6 months prior to the date informed consent is obtained that has not been treated with, or has failed to respond to, standard of care therapy.~18. History of anaphylaxis following any biologic therapy.~19. History of immune complex disease.~20. History of cancer:~    * Subjects who have had basal cell carcinoma, localised squamous cell carcinoma of the skin or in situ carcinoma of the cervix are eligible provided that the subject is in remission and curative therapy was completed at least 12 months prior to the date informed consent was obtained.~   * Subjects who have had other malignancies are eligible provided that the subject is in remission and curative therapy was completed at least 5 years prior to the date informed consent was obtained.~21. Tuberculosis requiring treatment within the 12 months prior to screening. Evaluation will be according to local guidelines as per local standard of care.~22. History of any known primary immunodeficiency disorder including a positive human immunodeficiency virus (HIV) test at screening, or the subject taking antiretroviral medications as determined by medical history and/or subject's verbal report.~23. History of chronic alcohol or drug abuse within 12 months prior to screening, or any condition associated with poor compliance as judged by the investigator.~24. History of attempted suicide or is at significant risk of suicide (either in the opinion of the investigator or defined as a yes to suicidal ideation questions no. 4 or 5 or answering yes to suicidal behaviour on the Columbia-Suicide Severity Rating Scale \[C-SSRS\] Screening version).~25. Any disorder, including but not limited to, cardiovascular, gastrointestinal, hepatic, renal, neurological, musculoskeletal, infectious, endocrine, metabolic, haematological, immunological, psychiatric, or major physical impairment that is not stable, in the opinion of the investigator, and could:~    * Affect the safety of the subject throughout the trial.~   * Influence the findings of the trial or their interpretations.~   * Impede the subject's ability to complete the entire duration of trial.~26. Any clinically significant abnormal findings in physical examination, vital signs, electrocardiogram (ECG), haematology, clinical chemistry, or urinalysis during the screening period, which in the opinion of the investigator, may put the subject at risk because of his/her participation in the trial, or may influence the results of the trial, or the subject's ability to complete entire duration of the trial.~27. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) level ≥2.0 times the ULN (upper limit of normal) at screening.~28. Positive hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B core antibody (HBcAb) or hepatitis C virus antibody (anti-HCV) serology at screening.
