Clinical Trial to Evaluate Efficacy and Safety of Dupilumab in Localized Scleroderma
- Conditions
- Localized Scleroderma
- Interventions
- Other: Placebo
- Registration Number
- NCT04200755
- Lead Sponsor
- University of Cologne
- Brief Summary
The DupiMorph study evaluates the efficacy of Dupilumab in localized scleroderma patients. Dupilumab is approved in the US and EU for the treatment of moderate/severe atopic dermatitis and since 2018 in the US for severe asthma therapy.
- Detailed Description
Localized scleroderma (LS) comprises a heterogenous group of sclerotic skin disorders. The incidence of LS is reported to be approximately 27 cases/ 1x106 and is hence approximately 2-3-fold higher compared to systemic scleroderma. Although in most cases not lethal the disease can significantly impact quality of life. Depending on the location of fibrosis, the disorder can cause bone deformities, alopecia, skin atrophy or lesions with severe hypo-/hyperpigmentation.
The disease is pathomechanistically poorly understood and no effective therapy is currently approved. The most promising treatments up to date include methotrexate ± pulsed corticosteroids or phototherapy with PUVA or UVA1. Yet, the number of treated patients in these studies is low. The response rates are low and inconsistent with approximately 50% of patients treated with UVA1 experience a recurrence within three years. There are no studies on efficacy of topical corticosteroids in LS. Small pilot studies and few case reports describe regression of lesions after topical calcineurin inhibitors. In addition, current therapies can only be applied for a short time during the acute phase due to the side effect profile after long-term use (e.g. skin atrophy in response to topical steroids, skin cancer in response to long term UV therapy, multiple side effects by long- term use of methotrexate and/or corticosteroids). Hence, this study evaluates, in comparison with placebo, the efficacy of Dupilumab administered subcutaneously every 14 days in patients with Morphea (plaque type) or generalized localized scleroderma (affecting at least three anatomic sites).

Patients with the following autoimmune disorders are excluded from the study: Multiple sclerosis, primary biliary cirrhosis, type I diabetes mellitus. Patients with the following autoimmune disorders are regarded as eligible: Lichen sclerosus, vitiligo, alopecia arthritis, thyroid diseases (e.g. Hashimoto disease). Patients with any autoimmune disorder not listed above should only be included after consultation with the principal coordinating investigator.

- Any condition or laboratory abnormality that, in the judgment of the investigator, would put the subject at unacceptable risk for participation in the study or may interfere with the assessments included in the study. E.g. uncontrolled psychiatric illness or history of clinical relevant drug abuse.
- Known hypersensitivity to any components of the IMP

Group Intervention Description Dupilumab Dupilumab 300Mg Solution for Injection 30 patients; Dupilumab s.c. injection; 2 ready-to-use syringes (600 mg) initial (V1), 1 ready-to-use syringe (300 mg) every 14 days (V2- V13) Dupilumab s.c. injection in healthy skin, 24 weeks Placebo Placebo 15 patients; placebo s.c. injection; 2 ready-to-use syringes initial (V1), 1 ready-to-use syringe every 14 days (V2-V13) placebo s.c. injection in healthy skin, 24 weeks
- Primary Outcome Measures
Name Time Method LoSCAT target lesion Baseline to End of Treatment Visit, 24 weeks Treatment response is assessed using the LoSCAT (Localized Scleroderma Cutaneous Assessment Tool). Target lesion will be assessed at Baseline and End of Treatment. Score reduction by 50% after 24 weeks (End of Treatment Visit V14) compared to Baseline Visit (V1) is defined as treatment response.
- Secondary Outcome Measures
Name Time Method LoSDI all lesions Baseline to Follow-Up Visit, 48 weeks Change in LoSDI (Localized Scleroderma Skin Damage Index) of all existing lesions during treatment, at End of Treatment Visit and during follow-up
Body temperature Baseline to Follow-Up Visit, 48 weeks Body temperature will be documented throughout the study.
Anti-nuclear antibodies (ANAs) levels Baseline to Follow-Up Visit, 48 weeks Change in anti-nuclear antibodies (ANAs) levels
mLoSSI all lesions Baseline to Follow-Up Visit, 48 weeks Change in mLoSSI (Localized Scleroderma Skin Activity Index) of all existing lesions during treatment, at End of Treatment Visit and during follow-up
RT-qPCR Baseline to End of Treatment Visit, 24 weeks Quantification of change in gene expression of genes identified by RNAseq in tissue of localized scleroderma patients after Dupilumab treatment: RT-qPCR of tissue biopsies obtained from the lesion (lilac ring, optional: center) before (baseline visit V1) and after treatment (End of Treatment Visit V14) and healthy skin before treatment
