Efficacy and Safety of Fucicort® Lipid Cream Compared to Combination Treatment With Fucidin® Cream Followed by Betamethasone (Lianbang Beisong®) Cream and Fucicort® Lipid Cream Vehicle in Clinically Infected Atopic Dermatitis/Eczema

Study Overview
=================
Brief Summary
-----------------
The trial is designed to compare the efficacy and safety of Fucicort® Lipid cream with the combination treatment of Fucidin® cream followed by betamethasone (Lianbang Beisong®) cream, or Fucicort® Lipid cream vehicle, when applied twice daily for two weeks. The trial is designed to demonstrate that treatment with Fucicort® Lipid cream is not inferior to the combination treatment with the mono component drugs, Fucidin® cream followed by betamethasone (Lianbang Beisong®) cream and that treatment with Fucicort® Lipid cream is superior to the treatment with Fucicort® Lipid cream vehicle. This is a 3-arm, parallel group, active- and vehicle-controlled trial comparing the efficacy and safety after 14 days treatment of Fucicort® Lipid cream, to Fucidin® cream followed by betamethasone (Lianbang Beisong®) cream, or Fucicort® Lipid cream vehicle, in subjects with clinically infected AD/eczema.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Fucicort® Lipid cream<br>Fucicort® Lipid cream is a combination of the antibiotic fusidic acid (20 mg/g) and the corticosteroid betamethasone (1 mg/g (as 17-valerate)). Twice daily for two weeks. | Drug: Fucicort® Lipid cream<br>* The active ingredient of Fucicort® Lipid cream are Fusidic acid and betamethasone. The pack size of Fucicort® Lipid cream is 15g.<br>|
| Active Comparator: Fucidin cream +betamethasone cream<br>The combination treatment with Fucidin® cream followed by betamethasone (Lianbang Beisong®) cream. Twice daily for two weeks. | Drug: Fucidin® cream<br>* The active ingredient of Fucidin® cream is Fusidic acid. The pack size of Fucidin® cream is 15g.<br>Drug: betamethasone (Lianbang Beisong®) cream<br>* The active ingredient of betamethasone (Lianbang Beisong®) cream is Betamethasone hydrate. The pack size of betamethasone (Lianbang Beisong®) cream is 15g.<br>|
| Placebo Comparator: Vehicle cream<br>The vehicle cream, also named as Fucicort® Lipid cream vehicle, is the identical cream of Fucicort Lipid cream but without the active ingredient. Twice daily for two weeks. | Drug: Fucicort® Lipid cream vehicle<br>* The active ingredient of Fucicort® Lipid cream vehicle is the identical cream of Fucicort® Lipid cream but without the active ingredient.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The percentage change in modified Eczema Area and Severity Index (m-EASI) on trunk and extremities at Day 15 | The percentage change in modified Eczema Area and Severity Index (m-EASI) on trunk and extremities from baseline to Day 15. The m-EASI is a composite score evaluating the severity of 4 clinical signs (erythema, oedema/induration/papulation, excoriation, and lichenification) and the extent of the disease on each of 3 body regions (upper limbs, trunk, and lower limbs) by use of standard scales. The maximum total score is 64.8, with higher values indicating more severe and/or more extensive condition. | from baseline to Day 15 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Investigator's Global Assessment (IGA) at Day 15 | The IGA of disease severity on the body (trunk and extremities, excluding the hands, head, and neck) will be assessed based on a visual evaluation by use of definitions of severity ranging from 0 (clear) to 5 (very severe). | at Day 15 | 
| Controlled disease according to IGA | Controlled disease according to IGA at Day 15, defined as subjects having at least 'moderate' disease at baseline achieving 'clear' or 'almost clear' disease severity or subjects having 'mild' disease at baseline achieving 'clear' according to IGA. | at Day 15 | 
| Proportion of patients with successful bacteriological response | Proportion of patients with successful bacteriological response, defined as pathogens present on target lesion at baseline and either: a) no pathogen present on target lesion at Day 15 ('confirmed eradication') or b) no swab taken at Day 15 as no lesion was evident ('presumptive eradication'). | at Day 15 | 
| Adverse event (AE)/serious adverse event (SAE) frequency | Adverse event (AE)/serious adverse event (SAE) frequency by preferred term. Ongoing (serious or non-serious) AE with a possible, probable, or non-assessable relationship to the IMP at the last visit in the treatment phase. The investigator should follow up on the outcome for 14±2 days or until the final outcome is determined. This follow-up visit can be made either as a phone call or as a regular visit according to the investigator's discretion. | baseline to Day 15 and 14±2 days follow up or until the final outcome is determined |
