  6. Able to provide written informed consent in accordance with federal, local, and institutional guidelines.

Exclusion Criteria:

  1. Active central nervous system (CNS) lupus (including seizures, psychosis, organic brain syndrome, cerebrovascular accident [CVA], cerebritis or CNS vasculitis) or active bleeding disorder within 60 days prior to the first day of study treatment.
  2. Clinical evidence of significant unstable or uncontrolled acute or chronic diseases other than SLE which, in the opinion of the investigator, could confound the results of the study, put the patient at undue risk, or interferes with protocol adherence, or a subject's ability to give informed consent.
  3. History or presence of congestive heart failure (New York Heart Association [NYHA]Class III to IV), symptomatic ischemia, clinically significant conduction abnormalities uncontrolled by conventional intervention, or myocardial infarction within 6 months prior to the first day of study treatment.
  4. Have severe lupus complications (Acute Lupus Pneumonitis, Diffuse Alveolar Hemorrhage, Chronic Interstitial Pneumonia, Pulmonary Hypertension, Pulmonary Embolism) severe lupus gastrointestinal diseases (Lupus Mesenteric Vasculitis, Protein-Losing Enteropathy, Pancreatitis, Intestinal Pseudo-Obstruction).
  5. History of any bleeding disorder secondary to SLE.

  7. Acute or chronic infections requiring systemic antibiotic, antifungal, or antiviral therapy within 60 days of the first day of study treatment.

  14. Use of cyclophosphamide or chlorambucil within five half-lives of screening.
  15. Use of rituximab, belimumab, or any other B cell-depleting or modulating therapies within 6 months of screening.
  16. Female patients who are pregnant or breastfeeding.
  17. Use of an investigational therapeutics within 30 days or 5 half-lives prior to screening, whichever is greater.
  18. Has a positive pregnancy test result at Screening or Check-in (females only).
  19. Women with childbearing potential are defined as all women who are physiologically able to have a pregnancy, unless they are using an efficient contraceptive method during treatment and within 30 days after discontinuation of treatment as below.

    1. Complete abstinence (if this is in line with the subject's preferred and usual lifestyle). Periodic abstinence (e.g., calendaring method, ovulation method, symptomatic body temperature method, post-ovulation method) and in vitro ejaculation are unacceptable contraceptive methods.
    2. Patients who have received female sterilization (bilateral ovariectomy with or without hysterectomy) or tubal ligation for at least 6 weeks prior to study treatment. In case of only unilateral ovariectomy, female fertility status must be confirmed by follow-up assessment of hormone levels.
    3. Combination of the following two methods:

      • Intrauterine device (IUD) or intrauterine system (IUS).
      • Barrier contraceptive methods: condoms or cervical cap (diaphragm or cervical cap) coated with spermicidal foam/gel/cream/vaginal suppositories. If women use oral contraceptives only, they should use the same contraceptives at a stable dose for at least 3 months before starting the study treatment.
    4. If women have at least 12 months of natural amenorrhea and are clinically compatible (e.g., at the corresponding age, with a history of vasomotor symptoms or received bilateral ovariectomy with or without hysterectomy, they are regarded as postmenopausal women with no childbearing potential. In case of only unilateral ovariectomy, female fertility status must be confirmed by follow-up assessment of hormone levels before the women can be considered to have no childbearing potential.
  20. Men who have sexual intercourse unless they use a condom during sexual intercourse and must not donate sperm from the first dose of study drug until 30 days after discontinuation of treatment and do not impregnate their sexual partners during the period. Vasectomized males are also required to use condoms to prevent the transmission of drugs through semen.
  21. Subject who, in the opinion of the Investigator, should not participate in this study.
