A Study to Evaluate the Safety and Tolerability of MOR106 Administered Concomitantly With Topical Corticosteroids, in Adult Participants With Moderate to Severe Atopic Dermatitis

Study Overview
=================
Brief Summary
-----------------
To investigate the safety and tolerability of repeated subcutaneous (s.c.) doses of MOR106 administered concomitantly with topical corticosteroids (TCS) in participants with moderate to severe atopic dermatitis (AD) who are candidates for systemic therapy.

Official Title
-----------------
A Randomized, Double-blind, Placebo-controlled, Multicentre Phase 2 Study to Evaluate the Safety and Tolerability of Subcutaneous MOR106 Administered Concomitantly With Topical Corticosteroids for Eight Weeks, in Adult Subjects With Moderate to Severe Atopic Dermatitis

Conditions
-----------------
Atopic Dermatitis

Intervention / Treatment
-----------------
* Drug: MOR106
* Drug: Placebo


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: A BMI 18 - 40 kilogram per meter square (kg/m^2), inclusive. Diagnosis of atopic dermatitis for at least one year since first diagnosis as per the Hanifin and Rajka Criteria. Eczema Area and Severity Index (EASI) ≥ 16 at the screening and at the baseline visit (Day 1 predose). Investigators' Global Assessment (IGA) score ≥ 3 (on the 0 to 4 IGA scale, in which 3 is moderate and 4 is severe) at the screening and baseline visits. Greater than or equal to 10% body surface area (BSA) of AD involvement at the screening and baseline visits. Willingness to use a non-medicated, simple bland emollient twice daily for at least 7 days before the baseline visit and throughout the study. Exclusion Criteria: Prior treatment with MOR106. Known hypersensitivity to any investigational medicinal product (IMP) ingredients as determined by the investigator (such as, but not limited to, anaphylaxis requiring hospitalization). AD lesions located predominantly (≥ 50% of cumulative lesional area) on face and genital areas. Any concurrent illness, condition, disability, or clinically significant abnormality (including laboratory tests, a New York Heart Association Classification (NYHA) ≥ III/IV) or clinically significant illness in the 3 months prior to initial IMP administration that, in the investigator's opinion, represents a safety risk for the participant's participation in the study, may affect the interpretation of clinical safety or efficacy data, or may prevent the participant from safely completing the assessments required by the protocol. Clinically significant abnormalities at the discretion of the investigator detected on vital signs or physical examination (other than AD) at screening or baseline (Day 1 predose). History of or a current immunosuppressive condition (e.g. human immunodeficiency virus [HIV] infection, as determined by a positive HIV test at screening). Active chronic or acute skin infection requiring treatment with systemic (oral, sc or iv) antibiotics, antivirals or antifungals within 4 weeks of baseline, or clinical signs of infective eczema within 7 days before baseline (Day 1 pre-dose). Having used any of the following treatments: Prior exposure to Dupilumab. Immunosuppressive/immunomodulating drugs (e.g. systemic corticosteroids, cyclosporine, mycophenolate-mofetil, interferon (IFN)-γ, azathioprine, methotrexate) within 4 weeks of baseline (Day 1) visit. Phototherapy (ultraviolet B [UVB] or Psoralen Ultraviolet A [PUVA]) for AD within four weeks of baseline (Day 1) visit. Treatment with TCS or topical calcineurin inhibitor (TCI) within 7 days before the baseline (Day 1) visit. Treatment with biologics within five half-lives (if known) or 12 weeks prior to baseline visit, whichever is longer. Regular use (more than two visits per week) of a tanning booth/parlor within 4 weeks of the baseline visit.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Adverse Event of Special Interest (AESIs), Serious Adverse Events (SAEs) | An Adverse Events (AE) was any untoward medical occurrence, new or worsening of any pre-existing condition, in a clinical study participant administered a medicinal product and which did not necessarily had to have a causal relationship with the treatment. TEAEs: AES with an onset date on or after the start date of the IMP administration. AESIs: skin-related events (SRE) (except exacerbation and infective exacerbation of AD) or injection site reactions (ISRs) as per common terminology criteria for AEs (Grade 3: ulceration or necrosis; severe tissue damage; operative intervention indicated, Grade 4: life-threatening consequences; urgent intervention indicated, Grade 5: death ). An SAE: AE that resulted in any of the following outcomes: death; life threatening; results in persistent or significant disability/incapacity; requires in-patient hospitalization or prolongation of existing hospitalization; congenital anomaly/birth defect; is medically significant. | Day 1 up to Day 169/Early discontinuation(ED) |
