Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria

2. Present for at least 1 year prior to the baseline visit (Baseline) with an inadequate response, in the judgement of the Investigator, to AD treatment with a topical regimen of corticosteroids, phosphodiesterase inhibitors or calcineurin inhibitors, or for whom topical treatments are otherwise medically inadvisable (eg, because of important side effect or safety risks)
3. Investigator Global Assessment (IGA) score = 3 at Screening and Baseline.
4. Eczema Area and Severity Index (EASI) score = 16 at Screening and Baseline
5. Body Surface Area (BSA) for total AD involvement = 10% at Screening and Baseline
6. Able and willing to apply a stable dose of a bland emollient twice a day to affected areas for at least 7 days before Baseline and to continue for the duration of the study
7. Females of child-bearing potential (FCBP) and males who have not undergone a vasectomy must abstain from heterosexual activities or agree to use effective contraception throughout the entire study period.
Minimum age
18 Years
Maximum age
75 Years
Sex

Can healthy volunteers participate?

Key exclusion criteria
1. Have any of the following laboratory abnormalities at Screening:

1. Hemoglobin = 90% of the lower limit of normal range (LLN)
2. White blood cell (WBC) below the LLN
3. Neutrophil count below the LLN
4. Platelet count below the LLN
2. Have undergone treatment with any of the following:

1. Topical agents such as corticosteroids, phosphodiesterase (PDE) inhibitors, Janus kinase (JAK) inhibitors, tacrolimus or pimecrolimus within 1 week prior to Baseline. Note that low to medium potency topical corticosteroids (TCS) are permitted after randomization to treat AD flares
2. Prior treatment with dupilumab or any antibody against IL-4Ra or IL-13
3. Systemic treatment for AD or other condition with steroids or other immunosuppressive/immunomodulating substances, e.g., cyclosporine, mycophenolate-mofetil, azathioprine, methotrexate or oral Janus kinase (JAK) inhibitors within 4 weeks prior to Baseline. Use of steroid inhalers and nasal corticosteroids is allowed.
4. Cell depleting agents, e.g. rituximab, within 6 months of Baseline or treatment with other biologics within 5 half-lives (if known) or 3 months prior to baseline visit, whichever is longer
5. Phototherapy (narrow band ultraviolet B [NBUVB], ultraviolet B [UVB], ultraviolet A1 [UVA1], psoralen + ultraviolet A [PUVA]), tanning beds, or any other light emitting device (LED), within 4 weeks of Baseline
6. = 2 bleach baths within 2 weeks of Baseline
7. Prescription emollient to treat AD (e.g. Atopiclair®, MimyX®, Epicerum®, etc.) within 2 weeks of Baseline
8. Any investigational drug within 30 days or within 5 half-lives, whichever is longer, before Baseline.
9. Live (attenuated) vaccine within 8 weeks of Baseline.
10. Treatment with systemic traditional Chinese medicine (TCM) or herbal medications within 4 weeks before Baseline or treatment with topical TCM or herbal medications within 1 week before Baseline visit
3. Have any of the following:

1. Infection requiring treatment with systemic antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals within 4 weeks before Baseline, or superficial skin infection, such as impetigo, within 2 weeks before the Baseline (subjects may be rescreened after the infection has resolved)
2. A history of parasitic infection (e.g. helminth), within 6 months of Baseline
3. Per investigator judgement, known or suspected history of immunosuppression within 6 months of Baseline, including a history of invasive opportunistic infections, such as aspergillosis, coccidioidomycosis, histoplasmosis, human immunodeficiency virus (HIV), listeriosis, pneumocystosis, or tuberculosis, despite infection resolution; or unusually frequent, recurrent or prolonged infections.
4. Any history of vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC)
5. A history of malignancy with the following exceptions: completely treated carcinoma in situ of cervix or non-metastatic squamous or basal cell carcinoma of the skin
6. Positive results at Screening for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb) or hepatitis C antibody with positive HCV RNA polymerase chain reaction; positive HIV serology at screening
7. An allergy to L-histidine, trehalose or Tween (polysorbate) 80
4. Women must not be pregnant, planning to become pregnant or breast-feed during the study
