Clinical Trial Summary

This is a double-blind, randomized, placebo-controlled multi-center phase IIA study to evaluate the clinical efficacy and safety of Fugan ointment versus placebo applied to involved skin of subjects with mild to moderate subacute eczema.

Description:

In this study, patients will be recruited and randomized in a ratio of 2:2:1 into Fugan bid group (Fugan AM + Fugan PM), Fugan qd group (Fugan AM + Placebo PM), and placebo group (Placebo AM + Placebo PM). Randomization will be stratified by disease severity (mild IGA=2 vs. moderate IGA=3).

The patients will be given 3-week treatment and followed up for two weeks after the treatment.

Screening period is set as 1 week. Subjects will be given 3-week treatment and followed up for two weeks after the treatment.

Approximately 310 subjects will be randomized to achieve 250 evaluable subjects completing the study.

Subacute eczema usually presents with papule, excoriations, crusting and pruritus. Occasionally patient will present with papulovesicle, blister and erosion. Patients also need to meet the requirement of:

• Subjects must have body surface area (BSA) disease involvement between 3-10% (inclusive) as assessed by palm method;

• IGA score of 2 or 3;

• Skin lesions should be on the trunk or extremities, without palms/soles, face/scalp, and vulvar areas involved;

3. Based on TCM theory (Zheng 2002), patients with TCM "damp - heat" symptoms to be included. It is subject to TCM investigator's assessment, and symptoms could be (but not limited to):

2. The subject has a current complication of overt bacterial, fungal or viral infection for which treatment with anti-infective are indicated;

3. Have the history of hepatic and kidney function insufficiency, hepatic dysfunction ALT or AST>1.5 ULN, kidney function BUN, Cr>1.5 ULN;

4. QT interval corrected according to Bazett's formula or QT interval corrected according to Fridericia's formula =450 msec; or QTc =480 msec in subjects with bundle branch block;

5. Have the history or examination verified by physical and screening of clinically significant cardiovascular, pulmonary, gastrointestinal, liver, renal, hematological, neurological, abnormalities and psychology disorders which will interfere with the efficacy and/or safety of the individual subject;

6. History of allergy to any component of test medications to be used in the study;

7. The subject has been exposed to below therapy within the set timeframe:

• Systemic administration of anti-histamine agents 1 week

• Systemic administration of corticosteroid 4 weeks;

• Topical corticosteroid agents administered in the diseased skin 1 week;

• Systemic administration of immunosuppressive drugs 4 weeks;

• Topical immunosuppressive drugs administered in the diseased skin 1 week;

• Systemic administration of any TCM drugs 2 weeks;

• Topical administration of any TCM drugs 1 week;

• UV therapy 4 weeks

Pregnant women (as confirmed by a positive urine human chorionic gonadotrophin (HCG) test), women who are breast feeding, or sexually active women of child bearing potential who are not practicing an acceptable method of birth control (birth control pill, patch, implant, barrier with spermicidal jelly, IUD, etc.), as determined by the investigator. An acceptable method of birth control must be used during the entire study in sexually active women of childbearing potential. A woman of childbearing potential is defined as one who is biologically capable of becoming pregnant. Abstinence is considered as a medically acceptable form of contraception;

10. The subject has received an investigational drug or participated in any other research trial within 30 days;

11. Other subjects that investigator deemed as unsuitable for the trial;

12. Subject's EASI score reaches 2 and above for lichenification and/or edema.
