E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
mild to moderate atopic dermatitis |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to demonstrate the effectiveness, tolerability and safety of CRx-197 in subjects with mild to moderate AD. |
|
E.2.2 | Secondary objectives of the trial | |
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
To be eligible to participate in this study, candidates must meet the following inclusion criteria:
I01 Subject must voluntarily give written informed consent I02 Subject must be 18 to 60 years of age I03 Subject must manifest mild to moderate AD diagnosed according to Hanifin and Rajka [Hanifin, 1980] • Two Lesional areas of 20-50 cm2 ADSI lesional score ≥4 and <13 • Difference in ADSI lesional score between lesions treated in the same subject should not be greater than 1 I04 TEWL in the lesional areas at least 12 g/m2h I05 Subject must be free from a condition/disease that the investigator feels will interfere with the interpretation of the study results. I06 Females of childbearing potential should either be surgically sterile (hysterectomy or tubal ligation), or should use a highly effective medically accepted contraceptive regimen. A highly effective method of birth control is defined as those which result in a lower failure rate (i.e. less than 1% per year) when used consistently and correctly such as implants, injectables, combined oral contraceptives, some IUDs, sexual abstinence or vasectomized partner.
