A Non-drug Study Profiling Cutaneous Lupus

This is a Phase 0, multiple-center observational study of biomarkers and clinical parameters
in patients with lupus, including discoid lupus erythematosus (DLE), subacute cutaneous LE
(SCLE) and active systemic lupus erythematosus (SLE). There is no study-related therapeutic
intervention and this protocol will not restrict or introduce any medical interventions
including medications. Study participants will undergo procedures that include collection of
urine, blood samples, and skin biopsy. At least 30 participants (≥10 DLE, ≥10 SCLE, and ≥10
SLE) will be enrolled in this study. All participants will continue to be managed by their
personal physicians per their standard of care. The data obtained in this study will help in
the evaluation of new therapeutics for lupus and may facilitate lupus drug discovery. A
blood sample for genomic analysis will be collected for research purposes from patients who
provide consent and where local regulations permit. There will be a single sample collection
time point for each patient. The safety assessments will include laboratory measurements
(serum chemistry and hematology), monitoring of adverse events (AEs) related to study
procedures, and physical examination.

Inclusion Criteria:

- have active DLE or active SCLE confirmed by histological analysis

- have a confirmed diagnosis of SLE with SLE Disease Activity Index (SLEDAI) of >6 and
current or historical positive ANA or anti-dsDNA

- have an active skin lesion that can be biopsied

- if using hydroxychloroquine or chloroquine, must be on stable doses for at least 2
months prior to screening.

Exclusion Criteria:

- have an active skin disease other than CLE

- have any known malignancy within the previous 5 years (with the exception of a
non-melanoma skin cancer that has been treated with no evidence of recurrence)

- have used a topical corticosteroid on active lesion

- have donated blood (volume >=500 mL) within 56 days prior to screening

- has been treated with drugs that are associated with CLE induction within 2
months prior to the screening

- have been treated with >10 mg/day prednisone therapy or equivalent in the last 4
weeks prior to screening.
