2. Willing and able to comply with the prescribed treatment protocol and evaluations for the duration of the trial.
3. Adult men or women = 18 and = 75 years of age
4. A diagnosis of DLE for = 6 months prior to screening supported by a history of:
a. A biopsy and/or
b. a clinical feature score of = 7 on the DLE Classification Criteria (DLECC) scale if a biopsy is not available.
5. Currently active discoid lupus with all the following:
a. Digital photography adjudicated with central reading to confirm a currently active discoid disease lesion.
b. CLASI-A score = 8 related to discoid lesions at Baseline
6. Treatment refractory DLE defined as active disease despite current or historical treatment with a systemic antimalarial, methotrexate, mycophenolate, azathioprine, dapsone, corticosteroid, thalidomide, or lenalidomide, OR documented history of intolerance to antimalarials and/or immunosuppressive medications.
7. Participants with active disease who currently are on any of the following therapies must have been on a stable dosage prior to Screening and must remain on a stable dosage through Randomization and for the entire trial as described below:
-Antimalarials must be at a stable dosage for at least 8 weeks prior to Screening and through Randomization.
-Methotrexate = 20 mg/week (oral or SC) at stable dosage and route of administration for at least 4 weeks prior to Screening and through Randomization.

-Azathioprine must be stable for at least 4 weeks prior to Screening and through Randomization.
-Corticosteroid equivalent to prednisone = 10 mg/day at stable dosage for at least 4 weeks prior to Screening and through Randomization.
-Topical corticosteroids and calcineurin inhibitors at stable dosage for at least 1 week prior to Screening and through Randomization.
8. Women of childbearing potential (WOCBP) (including those with an onset of menopause < 2 years prior to screening, nontherapy-induced amenorrhea for < 12 months prior to screening, or not surgically sterile [absence of fallopian tubes, ovaries and/or uterus]) must:

c. Refrain from egg retrieval and egg donation during the trial and until at least 6 months after the last IP administration.
-Note: Highly effective contraceptive methods (with a failure rate < 1% per year), when used consistently and correctly, include hormonal contraceptives (eg, combined oral contraceptives, patch, vaginal ring, injectable, or implant), some intrauterine devices or intrauterine systems, sexual abstinence, or vasectomized partner(s) (provided his vasectomy was performed = 4 months prior to Screening), tubal ligation or double barrier methods of contraception (eg, male condom with cervical cap, male condom wi
