Patients with HbA1c \>8% may be eligible for study if considered to be at low risk of infection and vascular complications at the discretion of study PI. * Positive SARS/Flu A/B/RSV (Panther), PCR - risk-based testing, only required if patient is symptomatic or has been exposed to someone with the virus. Note: Abnormal screening test(s) which exclude the patient may be repeated once within 4 weeks of the Screening Visit. If the repeat test(s) does not meet the above criteria, then the patient may be included in the study and will not be considered a screen failure. * Receipt of any of the following: 1. Azathioprine \>200 mg/day 2. Mycophenolate mofetil \> 3 g/day or mycophenolic acid \>2.16 g/day 3. Oral, SC, or intramuscular methotrexate \>25 mg/week 4. Mizoribine \>150 mg/day. Leflunomide more than 20 mg and any other immunosuppressant usage at the discretion of the PI. * Receipt of any investigational product (small molecule or biologic agent) within 4 weeks or 5 half-lives prior to week 0 (day 1), whichever is greater. * Receipt of any commercially available biologic agent within 5 half-lives prior to signing of the ICF * Receipt of B cell depleting therapy (including but not limited to belimumab, ocrelizumab, ofatumumab, atacicept, Obinutuzumab, or rituximab), \<26 weeks prior to the signing of the consent for all B-cell depleting therapy or \<40 weeks prior to the signing of the ICF for atacicept. * Receipt of any of the following: (a) Intra-articular, intramuscular or IV corticosteroids within 4 weeks prior to Day 1 (b) Any live or attenuated vaccine within 8 weeks prior to signing the ICF (administration of killed vaccines is acceptable) * History or evidence of suicidal ideation within the past 6 months; or any suicidal behavior within the past 12 months based on screening or at baseline. * Recent cardiac or stroke event (with in the last year prior to week 0 (day 1)) * Active SLE disease with SLEDAI 2K \>6 at the time of screening. * Active severe or unstable neuropsychiatric SLE including, but not limited to: aseptic meningitis; cerebral vasculitis; myelopathy; demyelination syndromes (ascending, transverse, acute inflammatory demyelinating polyradiculopathy); acute confusional state; impaired level of consciousness; psychosis; acute stroke or stroke syndrome; cranial neuropathy; status epilepticus; cerebellar ataxia; and mononeuritis multiplex: 1. That would make the subject unable to fully understand the ICF OR 2. Where, in the opinion of the Principal Investigator (PI), protocol specified SOC is insufficient and utilization of a more aggressive therapeutic approach, such as adding IV cyclophosphamide and/or high dose IV pulse corticosteroid therapy or other treatments not permitted in the protocol, is indicated * Active severe SLE-driven renal disease where, in the opinion of the PI, protocol specified standard of care (SOC) is insufficient and utilization of a more aggressive therapeutic approach, such as adding IV cyclophosphamide and/or high dose IV pulse corticosteroid therapy or other treatments not permitted in the protocol, is indicated. * History of or current diagnosis of catastrophic or severe anti-phospholipid syndrome within 1 year prior to signing the ICF.

Subjects refusing HIV testing during the screening period will not be eligible for study participation. * Confirmed positive test for hepatitis B serology for: 1. Hepatitis B surface antigen (HBsAg), OR 2. Hepatitis B core antibody (HBcAb) 3. If positive for HBcAb, hepatitis B virus (HBV) DNA will be checked. If HBV DNA is detected above the lower limit of quantitation (LLOQ) at screening subject will be excluded Note: Subjects who are only HBcAb positive at screening will be tested every month for HBV DNA. To remain eligible for the study, the subject s HBV DNA levels must remain below the LLOQ as per the central laboratory. * Positive test for hepatitis C antibody along with detectable Hepatitis C viral RNA. * Any severe herpes infection at any time prior to Week 0 (Day 1), including, but not limited to, disseminated herpes (ever), herpes encephalitis (ever), recurrent herpes zoster (defined as 2 episodes within 2 years) or ophthalmic herpes (ever) * Any herpes zoster, cytomegalovirus (CMV) or Epstein-Barr virus infection that has not completely resolved within 12 weeks prior to signing the ICF. * Any of the following: 1.
