Brief Summary

The primary purpose of this study is to evaluate the potential effectiveness of 24 weeks of MMF within previously discovered immunologically defined subsets of SLE patients. Treatment effects will be evaluated within the individual immunologically-homogenous subsets defined at screening. This study will also explore and compare pre-randomization gene expression patterns among responders and non-responders to MMF and MMF plus voclosporin, use comprehensive immunophenotyping to study the immunologic changes that accompany treatment- induced disease improvement and to better understand immunologic changes associated with the loss of clinical response.

Detailed Description

The study was conducted in 3 stages with a maximum participant follow-up time of 56 weeks. Stage 1 was a treatment withdrawal period lasting up to 4 weeks where consenting participants receive up to 3 intramuscular injections of a long-acting corticosteroid to achieve amelioration of symptoms. In addition, participants withdraw from all other treatments for lupus with the following exceptions:

(i) as needed (PRN) nonsteroidal anti-inflammatory treatments may be started or continued, (ii) PRN topicals may be continued, (iii) hydroxychloroquine, chloroquine, or quinacrine may be continued at any stable dose, and (iv) prednisone, if<= 10 mg/day, may be continued at stable doses but not started.

Qualifying participants from Stage 1 were randomized (1:1) into Stage 2 to receive either MMF or placebo for MMF for up to 48 weeks. Participants who experienced a Stage 2 treatment failure at or before the Week 24 visit and a corticosteroid injection was deemed sufficient for treatment without new or increased lupus medication were eligible to re-randomize (1:1) into Stage 3 to receive either MMF + Voclosporin or MMF + Placebo for Voclosporin for up to 24 Weeks.

Participants who did not experience a Stage 2 treatment failure at or before the Stage 2 Week 48 visit were to return for an End of Study/Safety Follow-up visit 4 weeks after the final dose of study-provided medication. Similarly, participants who did not experience a Stage 3 treatment failure at or before the Stage 3 Week 24 visits were asked to return for an End of Study/Safety Follow-up visit 4 weeks after the final dose of study provided medication.

1. Aged ≥ 18 and ≤ 60 years at the time of informed consent.

2. Meets EULAR/ACR 2019 criteria for SLE.

3. Moderately severe, active, but non-organ threatening disease. Specifically, signs or symptoms meeting criteria for a minimum of:

Participants who meet the following criterion at the Stage 2 Randomization Visit may proceed to randomization in Stage 2:

7. After completion of corticosteroid injection(s) and prior to randomization in Stage 2, the participant and his/her physician must agree that disease activity has improved sufficiently from screening such that randomization is acceptable.

1. The physician must score the CGI-C as "moderately better" or "much better" prior to randomization.

• The reference value for the CGI-C should be the investigator's determination of the participant's condition at the Screening Visit.

2. The participant must agree that his/her symptoms have improved (yes/no).

Exclusion Criteria

2. 2 BILAG B (moderate) activity scores in any organ systems; or

3. 1 BILAG B (moderate) activity score in any organ systems and a SELENA-SLEDAI score of ≥ 6.

• If there is only 1 BILAG B score:

• If a musculoskeletal BILAG B is scored due to moderate arthritis, where some loss off functional range of movements was present on several days over the last 4 weeks, there must also be a minimum of at least 3 joints that are both tender and swollen due to lupus disease activity in wrists, MCPs or PIPs for the participant to qualify.
• If a mucocutaneous BILAG B is scored due to acute or subacute cutaneous skin eruption, the rash must cover at least 4% of the body surface area for the participant to qualify. Any active discoid lesion or other form of chronic cutaneous lupus would be qualifying.

4. Approval, by an adjudication committee of a brief entry packet describing the type, severity and duration of symptoms meeting the minimal criteria for entry. The participant will meet this criterion if the committee is confident of all of the following:

1. Convincing diagnosis of SLE,

2. Active disease, due to SLE, warranting the potential of dual therapy with potent immune modulators,

3. No medical or other condition to contraindicate participation in a placebo-controlled, outpatient study of this design.

5. Women of childbearing potential must have a negative serum pregnancy test at screening.

6. Able or willing to use reliable methods of contraception, as outlined in the Mycophenolate REMS brochure for health care providers, from 4 weeks prior to first randomization to 6 weeks after completion of the study. This criterion applies to females of reproductive potential.

Participants who meet any of the following criteria are not eligible for randomization as study participants:

2. History of confirmed Class 3-5 nephritis > 2 years ago in the absence of documented treatment including both induction and maintenance therapy,

3. UPCR > 1 g/g at screening, • If UPCR is > 0.5 g/g and ≤ 1 g/g at screening, then a second assessment must be completed with at least 1 week between assessments. If the second assessment is > 1 g/g or has increased by ≥ 0.3 g/g, then the participant is excluded.

4. Evidence of chronic kidney disease defined as eGFR < 45 mL/min per 1.73 m2 at screening, where 175 x (Creatinine/88.4)-1.154 x (Age)-0.203 x (0.742 if female) x (1.212 if of African descent).

5. History of cirrhosis or chronic liver disease unrelated to SLE other than fatty liver disease.

6. History, within 1 year of the Screening Visit, of uncontrolled SLE that would have warranted a BILAG A (except mucocutaneous, constitutional, musculoskeletal) including, but not limited to, hemolytic anemia, neuropsychiatric lupus, or interstitial lung disease.

7. Uncontrolled HTN at the Screening or Randomization Visits defined as a blood pressure > 150/100 with or without treatment, not to exceed 3 complementary antihypertensive treatments.

22. Positive results from a SARS-CoV-2 antigen test administered 2 days prior to and on the day of first randomization.

23. Positive Quantiferon Gold (or equivalent) assay. Indeterminate Quantiferon Gold (or equivalent) assays must be repeated (with same or other interferon gamma release assay per local policy) and shown to be negative. Alternatively, if the Quantiferon Gold (or equivalent) assay remains indeterminate, a participant must have a negative PPD. Finally, if the participant has had the BCG vaccine or has some other condition complicating the interpretation of TB testing, consultation with infection disease specialist must be obtained.

• Participants diagnosed with latent TB are eligible but must have received appropriate prophylaxis for 30 days prior to initiation of Stage 2 treatment.

24. Serologic evidence at screening of chronic infections including:

1. HIV infection.

3. Hepatitis C as indicated by anti-hepatitis C antibody positivity; if a participant is Hepatitis C antibody positive, they will be eligible to participate in the study if they are negative for viral load at Screening.

25. Current, diagnosed, or self-reported drug or alcohol abuse within the last 6 months that, in the opinion of the investigator, would interfere with the ability to comply with study protocol.

26. Recipient of live attenuated vaccine(s) within 8 weeks of the Screening Visit.

27. Use of investigational drugs (excluding SARS-CoV-2 vaccinations or SARS-CoV2 therapeutics) within 8 weeks of the Screening Visit or 5 half-lives, whichever is longer.

28. Past or current mental or physical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the investigator, may pose additional risks from participation in the study, may interfere with the participant's ability to comply with study requirements, or may impact the quality or interpretation of the data obtained from the study.
