Details and patient eligibility

About

The purpose of this study is to evaluate the therapeutic effect of fumaric acid esters (Fumaderm®) in the treatment of Cutaneous Lupus Erythematosus with respect to proportion of responders based on the Revised Cutaneous Lupus Disease Area and Severity Index (RCLASI) activity score for skin lesions at baseline and after 24 weeks of treatment or at the latest assessment for patients who withdrew prematurely (Last Observation Carried Forward, LOCF).

Full description

At screening, patients meeting the inclusion and exclusion criteria will be asked to provide written informed consent. Male patients and female patients without childbearing potential will also complete other screening procedures including vital signs, physical examination, and patients and physicians efficacy assessments.

Treatment will be started as soon as possible after screening and not later than 1 month after screening.

The patients will receive a treatment either with Fumaderm® initial and/or Fumaderm® enteric-coated tablets. Fumaderm® initial will be usually administered during the first three weeks of treatment and / or during the trial when adaptation of the daily dosage will be required due to the occurrence of adverse reactions, e.g gastrointestinal.

Throughout the trial, daily use of sunscreens (sun protection factor, SPF≥50) will be recommended to all patients. The management of CLE may also involve the use of topical medications, such as topical steroids, or systemic rescue medications, such as antimalarials.

All patients will be evaluated with the RCLASI, PAGI and VAS after 12 weeks and at the end of treatment. Adverse Events (AE) will be recorded at each visit until 4 weeks after the end of therapy. Serious Adverse Events (SAE) must be reported if they occur up to 4 weeks after the end of therapy.

Inclusion criteria

A clinical and histological diagnosis of CLE (DLE, SCLE, LET, without major systemic involvement) who failed to response to topical corticosteroids;
Total RCLASI activity score of >6 (at least 3 points in at least 2 locations) on an assessment of erythema, scale/hyperkeratosis, edema/infiltration and subcutaneous nodule/plaque of the lesion (mucous membrane lesions/alopecia excluded);
Women of childbearing potential must agree to use at least one primary method of contraception and preferably, at the same time, a secondary method of contraception from the time of screening, throughout trial treatment, and for at least one month after finishing treatment.
Signed informed consent.

Exclusion criteria

Patients unable to comply with the requirements of the study;
Only scarred cutaneous target lesions without activity;
