Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Written informed consent and any locally required authorisation obtained from the subject prior to performing any protocol-related procedures, including screening evaluations.
  • Age 18 and above.
  • Diagnosis of AD as defined by the Hanifin and Rajka (1980) criteria for AD (33; Appendix 5).
  • Diagnosis of AD for ≥1 year.
  • 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.
Show all 16Show fewer
  • 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.
  • AD involvement of ≥10% body surface area at screening and baseline (visit 3).
  • An EASI score of ≥12 at screening and 16 at baseline.
  • An IGA score of ≥3 at screening and at baseline.
  • 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.
  • 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).
  • 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).

Who cannot join

  • Concurrent enrolment in another clinical trial where the subject is receiving an IMP.
  • Previous randomisation in tralokinumab trials.
  • Active dermatologic conditions that may confound the diagnosis of AD or would interfere with assessment of treatment, such as scabies, cutaneous lymphoma, or psoriasis.
  • Known active allergic or irritant contact dermatitis that is likely to interfere with the assessment of severity of AD.
  • 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.
  • Treatment with the following medications within 4 weeks prior to randomisation:

  • 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.
  • Receipt of any investigational non-biologic agent within 5 half-lives prior to randomisation.
  • Receipt of blood products within 4 weeks prior to screening.
  • Major surgery within 8 weeks prior to screening, or planned in-patient surgery or hospitalisation during the trial period.

About this study

Official title: A Randomised, Double-blind, Placebo-controlled, Phase 3 Trial to Evaluate the Efficacy and Safety of Tralokinumab Monotherapy in Subjects With Moderate to Severe Atopic Dermatitis Who Are Candidates for Systemic Therapy

Primary objective:

To evaluate the efficacy of tralokinumab compared with placebo in treating moderate to severe atopic dermatitis (AD).

Secondary objectives:

To evaluate the efficacy of tralokinumab on severity and extent of AD, itch, and health related quality of life compared with placebo.

Maintenance objective:

To evaluate maintenance of effect with continued tralokinumab dosing up to 52 weeks compared to placebo for subjects achieving clinical response at Week 16.

Read the detailed description

Subjects found eligible following the screening period were randomized 3:1 to initial treatment with tralokinumab 300 mg every 2 weeks (Q2W) or placebo. Randomization was stratified by region (Asia, Australia, Europe, and North America) and disease severity (Investigator's Global Assessment [IGA] 3 or 4).

Subjects achieving a clinical response at Week 16 (defined as IGA of 0 or 1 on a 5-point scale ranging from 0 [clear] to 4 [severe], or at least 75% reduction in Eczema Area and Severity Index [EASI] score from baseline [EASI75]) continued into maintenance treatment that continued until Week 52.

Subjects randomized to tralokinumab in the initial treatment period and who achieved a clinical response at Week 16 (defined by IGA 0 or 1, or EASI75) were re-randomized 2:2:1 to one of the following Q2W maintenance regimens stratified by region (Asia, Australia, Europe, and North America) and IGA response at Week 16 (IGA 0/1 or IGA >1):

  • Tralokinumab 300 mg Q2W.
  • Tralokinumab 300 mg Q4W (alternating dose administrations tralokinumab 300 mg and placebo).
  • Placebo.

Subjects randomized to placebo in the initial treatment period who achieved a clinical response at Week 16 (defined by IGA 0 or 1, or EASI75) continued to receive placebo Q2W in the maintenance treatment period.

Subjects not achieving a clinical response at Week 16 as well as those who met the criteria listed below during maintenance treatment were transferred to open-label tralokinumab 300 mg Q2W treatment with optional use of topical corticosteroid (TCS) up to Week 52.

Transfer to open-label treatment during maintenance:

Subjects with IGA=0 at Week 16: IGA of at least 2 and not achieved EASI75 over at least a 4-week period (i.e. over 3 consecutive visits).

Subjects with IGA=1 at Week 16: IGA of at least 3 and not achieved EASI75 over at least a 4-week period (i.e. over 3 consecutive visits).

Subjects with IGA >1 at Week 16: not achieved EASI75 over at least a 4-week period (i.e. over 3 consecutive visits).

Subjects transferring to open-label treatment had the option to self-administer tralokinumab in their home after adequate training (at 3 dosing visits in the open-label period after additional consent has been obtained) by site staff at the investigator's discretion.

After completion of the maintenance treatment period (or open-label treatment), all subjects, except for those who entered the open-label long-term extension trial, continued in a 14-week off-treatment follow-up period for the assessment of safety and anti-drug antibody (ADA).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TralokinumabDrug

    Tralokinumab is a human recombinant monoclonal antibody of the IgG4 subclass that specifically binds to human IL-13 and blocks interaction with the IL-13 receptors. It is presented as a liquid formulation for subcutaneous (SC) administration

  • PlaceboDrug

    Placebo contains the same excipients, in the same concentration only lacking tralokinumab

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Subjects With Investigator's Global Assessment (IGA) Score of 0 (Clear) or 1 (Almost Clear) at Week 16.

    The IGA is an instrument used in clinical trials to rate the severity of the subject's global AD and is based on a 5-point scale ranging from 0 (clear) to 4 (severe).

    Measured: At Week 16

  2. Subjects Achieving at Least 75% Reduction in Eczema Area and Severity Index [EASI].

    The EASI is a validated measure used in clinical practice and clinical trials to assess the severity and extent of AD. The EASI is a composite index with scores ranging from 0 to 72, with higher values indicating more severe and/or more extensive condition.

    Measured: At Week 16

Secondary outcomes (15)

  1. Reduction of Worst Daily Pruritus Numeric Rating Scale (Weekly Average) of at Least 4 From Baseline to Week 16.

    Subjects will assess their worst itch severity over the past 24 hours using an 11 point NRS ('Worst Daily Pruritus NRS') with 0 indicating 'no itch' and 10 indicating 'worst itch imaginable'.

    Measured: Week 0 to Week 16

  2. Change in Scoring Atopic Dermatitis (SCORAD) From Baseline to Week 16.

    The SCORAD is a validated tool to evaluate the extent and severity of AD lesions, along with subjective symptoms. The maximum total score is 103, with higher values indicating more severe disease.

    Measured: Week 0 to Week 16

  3. Change in Dermatology Life Quality Index (DLQI) Score From Baseline to Week 16.

    The DLQI is a validated questionnaire with content specific to those with dermatology conditions. It consists of 10 items addressing the subject's perception of the impact of their skin disease on different aspects of their quality of life (QoL) over the last week such as dermatology-related symptoms and feelings, daily activities, leisure, work or school, personal relationships, and the treatment. Each item is scored on a 4 point Likert scale (0 = not at all/not relevant; 1 = a little; 2 = a lot; 3 = very much). The total score is the sum of the 10 items (0 to 30); a high score is indicative of a poor QoL.

    Measured: Week 0 to Week 16

  4. Subjects With Investigator's Global Assessment (IGA) Score of 0 (Clear) or 1 (Almost Clear) at Week 52 Among Subjects With IGA of 0/1 at Week 16

    The IGA is an instrument used in clinical trials to rate the severity of the subject's global AD and is based on a 5-point scale ranging from 0 (clear) to 4 (severe).

    Measured: At Week 52

  5. Subjects With at Least 75% Reduction in Eczema Area and Severity Index [EASI] at Week 52 Among Subjects With EASI75 at Week 16

    The EASI is a validated measure used in clinical practice and clinical trials to assess the severity and extent of AD. The EASI is a composite index with scores ranging from 0 to 72, with higher values indicating more severe and/or more extensive condition.

    Measured: At Week 52

  6. Safety and Tolerability: Adverse Event (AE) /Serious Adverse Event (SAE) Frequency

    Overall summary of AEs and SAEs during the Initial treatment period is presented. For list of AEs and SAEs by MedDRA system organ class (SOC) and preferred term (PT) during the entire trial period (including safety follow-up), see Adverse Events Overview section.

    Measured: Week 0 to Week 16

  7. Frequency of Anti-drug Antibodies

    Anti-tralokinumab antibody levels were analysed using a validated bioanalytical method

  8. Subjects Achieving at Least 50% Reduction in Eczema Area and Severity Index [EASI] at Week 16

    The EASI is a validated measure used in clinical practice and clinical trials to assess the severity and extent of AD. The EASI is a composite index with scores ranging from 0 to 72, with higher values indicating more severe and/or more extensive condition.

    Measured: At Week 16

  9. Subjects Achieving at Least 90% Reduction in Eczema Area and Severity Index [EASI] at Week 16.

    The EASI is a validated measure used in clinical practice and clinical trials to assess the severity and extent of AD. The EASI is a composite index with scores ranging from 0 to 72, with higher values indicating more severe and/or more extensive condition.

    Measured: At Week 16

  10. Change From Baseline to Week 16 in Eczema Area and Severity Index [EASI] Score

    The EASI is a validated measure used in clinical practice and clinical trials to assess the severity and extent of AD. The EASI is a composite index with scores ranging from 0 to 72, with higher values indicating more severe and/or more extensive condition.

    Measured: At Week 16

  11. Subjects Achieving at Least 75% Reduction in Scoring Atopic Dermatitis (SCORAD) at Week 16.

    The SCORAD is a validated tool to evaluate the extent and severity of AD lesions, along with subjective symptoms. The maximum total score is 103, with higher values indicating more severe disease.

    Measured: At Week 16

  12. Subjects Achieving at Least 50% Reduction in Scoring Atopic Dermatitis (SCORAD) at Week 16.

    The SCORAD is a validated tool to evaluate the extent and severity of AD lesions, along with subjective symptoms. The maximum total score is 103, with higher values indicating more severe disease.

    Measured: At Week 16

  13. Change From Baseline to Week 16 in Worst Daily Pruritus NRS (Weekly Average).

    Subjects will assess their worst itch severity over the past 24 hours using an 11 point NRS ('Worst Daily Pruritus NRS') with 0 indicating 'no itch' and 10 indicating 'worst itch imaginable'

    Measured: Baseline to Week 16

  14. Reduction of Worst Daily Pruritus NRS (Weekly Average) ≥3 From Baseline to Week 16.

    Subjects will assess their worst itch severity over the past 24 hours using an 11 point NRS ('Worst Daily Pruritus NRS') with 0 indicating 'no itch' and 10 indicating 'worst itch imaginable'.

    Measured: Baseline to Week 16

  15. Reduction From Baseline to Week 16 of Dermatology Life Quality Index (DLQI) of ≥4 Points Among Subjects With Baseline DLQI ≥4.

    The DLQI is a validated questionnaire with content specific to those with dermatology conditions. It consists of 10 items addressing the subject's perception of the impact of their skin disease on different aspects of their QoL over the last week such as dermatology related symptoms and feelings, daily activities, leisure, work or school, personal relationships, and the treatment. Each item is scored on a 4 point Likert scale (0 = not at all/not relevant; 1 = a little; 2 = a lot; 3 = very much). The total score is the sum of the 10 items (0 to 30); a high score is indicative of a poor QoL.

    Measured: Baseline to Week 16

A Phase 3 study testing Tralokinumab in people with Atopic Dermatitis, run by LEO Pharma at 115 sites in 9 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 48 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 115 sites in United States, Canada, United Kingdom, South Korea, Poland and 4 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Aug 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Subjects With Investigator's Global Assessment (IGA) Score of 0 (Clear) or 1 (Almost Clear) at Week 16. (time frame: At Week 16). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03160885, which also lists 7 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Mar 2025.
