ACT16404 Enrolling

Cutaneous Lupus Erythematosus Research Trial (20 Weeks)

Age: 18 Years

Adults aged 18 to 80 years old with cutaneous lupus erythematosus (either in the form of discoid/chronic or subacute) for at least 3 months, may qualify to participate. Individuals need a histologically confirmed and documented diagnosis of cutaneous lupus erythematosus (within one year prior to screening OR confirmed during screening) to be eligible. Active skin lesions and moderate to severe disease, must also be present.

Participants will receive investigational oral medication (active study drug) or placebo. Study medication and study-related procedures will be provided. Reimbursement for study-related expenses may be provided.

Study participation will last about 20 weeks and involve about 6 visits to the study centre.
