Current Primary Outcome Measures (submitted: January 17, 2019)

Number and Percentage of Subjects Who Achieved a Response at Week 24 According to the Modified British Isles Lupus Assessment Group (BILAG)-Based Composite Lupus Assessment (mBICLA) Score [ Time Frame: At Week 24 visit ]

The primary endpoint was evaluated by determining if there was a dose-response relationship between the mBICLA response rate at Week 24 and the dose administered, using the Multiple Comparison Procedure - Modelling (MCP-Mod) methodology. The existence of several candidate parametric models was assumed and multiple comparison techniques were used to choose the model(s) most likely to represent the true underlying dose-response curve. The selected model could further be used to guide the choice of adequate doses. mBICLA responders were defined as subjects who met all of the following criteria:

1. BILAG-2004 normal improvement: all A scores at Baseline improved to B, C or D, and all B scores improved to C or D.
2. No worsening in disease activity: no new BILAG-2004 A scores and ≤ 1 new increase to B.
3. No worsening of total mSLEDAI-2K score from Baseline.
4. No significant deterioration (< 10% worsening from Baseline) in PGA.
5. No treatment failure (including the premature

• Number and Percentage of Subjects With Modified Systemic Lupus Erythematosus Responder Index (mSRI-4) Response at Week 24 and Week 48 [ Time Frame: At Week 24 and Week 48 ]
  The composite index mSRI-4 enables quantification of decrease and increase in disease activity in a broad spectrum of manifestations thereby offering a comprehensive assessment of SLE disease status. mSRI combines advantages from 3 validated measurement tools. The mSRI-4 criteria for response are:

  1. modified SLE disease activity index 2000 (mSLEDAI-2K): ≥ 4 point reduction (covers global disease improvement),
  2. British Isles Lupus Assessment Group 2004 (BILAG-2004): no new A domain score and no more than 1 new increase to B (covers organ-specific disease improvement),
  3. Physician's Global Assessment (PGA) (is used as validity and safety net for items that were not addressed by the other two indices): < 10% increase from Baseline (no worsening) When all 3 criteria are met, the subject is a mSRI-4 responder at that time point.

  Subjects who were treatment failures or discontinued from treatment were considered non-responder after treatment failure/discontinuation.

• Change From Baseline in Modified Systemic Lupus Erythematosus Disease Activity Index 2000 (mSLEDAI-2K) Score at Week 24 and Week 48 [ Time Frame: At Week 24 and Week 48 ]
  The Systemic Lupus Erythematosus Disease Activity Index 2000 is a 1-page weighted score for 24 items (seizure, psychosis, organic brain syndrome, visual disturbance, cranial nerve disorder, lupus headache, cerebrovascular accident, vasculitis, arthritis, myositis, urinary casts, hematuria, proteinuria, pyuria, rash, alopecia, mucosal ulcers, pleurisy, pericarditis, low complement, etc). The manifestations felt to be most commonly contributing to disease activity are included and scored based on the presence (= 1 multiplied by weight) or absence (= 0) within 30 days prior to the evaluation. The total score ranges from 0-105 (= sum of individual scores), with 105 being higher disease activity. mSLEDAI-2K derives from the standard index by omitting low complement. Mean changes from baseline were derived from an ANCOVA model with treatment as factor and baseline mSLEDAI-2K Score and geographic region as covariates. A negative change from baseline reflects an improvement.
• Number and Percentage of Subjects With BILAG-2004 Normal Improvement at Week 24 and Week 48 [ Time Frame: At Week 24 and Week 48 ]

• BILAG-2004 Total Score at Baseline, Week 24 and Week 48 [ Time Frame: At Baseline, Week 24 and Week 48 ]
  The British Isles Lupus Assessment Group 2004 (BILAG-2004) is a comprehensive composite clinical index that has been developed based on the principle of a physician's intention to treat using a nominal consensus approach. In the index, the nine systems (not organs) considered are: constitutional, mucocutaneous, neuropsychiatric, musculoskeletal, cardiorespiratory, gastrointestinal, renal, ophthalmic and hematological. Disease activity in each of the nine systems is categorized into five levels: grades A (= severe disease activity requiring systemic high dose oral corticosteroids, i.v. pulse corticosteroids, etc.) to E (= system never involved). BILAG total score is derived by assigning the following value to each grade and summing the sores over all organ systems: A = 12, B = 8, C = 1, D/E = 0. The total score ranges from 0-108, with 108 representing high disease activity in all 9 systems requiring high doses of corticosteroids, starting/increasing immunosuppressive drugs, etc.

  The Short Form (36) Health Survey (SF-36) consists of 36 items that can be summarized into 8 domains: physical functioning, role limitations due to physical health problems (role-physical), bodily pain, general health, vitality, social functioning, role limitations due to emotional problems (role-emotional), and mental health. Two summary measures, the physical component summary and the mental component summary, can be derived based on these domain scores. Each score is directly transformed into a 0-100 score on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability. Mean changes from baseline were derived from an analysis of covariance (ANCOVA) model with treatment as factor and baseline SF-36 Score and geographic region as covariates.

• Change From Baseline in Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI) Activity Score at Week 12, Week 24 and Week 48 [ Time Frame: At Week 12, Week 24 and Week 48 ]
  CLASI Activity is scored based on erythema, scale/hyperkeratosis, mucous membrane involvement, acute hair loss and nonscarring alopecia. Evaluation of erythema and scale/hyperkeratosis is based on a table: rows represent anatomical areas and columns represent major clinical symptoms. The extent of involvement for each of the skin symptoms is documented for each anatomic area (erythema: 0=absent, 1=pink, 2=red, 3=dark red; scale: 0=absent, 1=scale, 2=verrucous/hypertrophic). Mucous membrane involvement and acute hair loss are scored based on the presence (=1) or absence (=0). Nonscarring alopecia is scored as 0=absent, 1=diffuse/non-inflammatory, 2=focal or patchy in 1 quadrant, 3=focal or patchy in >1 quadrant. The total score ranges from 0-70, with higher scores indicating more severe skin disease. Mean changes from baseline were derived from an ANCOVA model with treatment as factor and baseline CLASI Activity Score and geographic region as covariates. Negative change = improvement
• Change From Baseline in CLASI Damage Score at Week 12, Week 24 and Week 48 [ Time Frame: At Week 12, Week 24 and Week 48 ]
  CLASI Damage is scored based on dyspigmentation and scarring. Evaluation of dyspigmentation and scarring is based on a table: rows represent anatomical areas and columns represent major clinical symptoms. The extent of involvement for each of the skin symptoms is documented for each anatomic area (dyspigmentation: 0=absent, 1=present; scarring: 0=absent, 1=scarring, 2=severely atrophic scarring or panniculitis). Subjects are also asked whether dyspigmentation due to SLE lesions usually remains visible for >12 months, which is considered permanent and results in doubling of the dyspigmentation score. Scarring alopecia is scored as follows: 0=absent, 3=1 quadrant, 4=2 quadrants, 5=3 quadrants, 6=affects the whole skull. Total score ranges from 0-56, with higher scores indicating more damaged skin. Mean changes from baseline were derived from an ANCOVA model with treatment as factor and baseline CLASI Damage Score and geographic region as covariates. Negative change = improvement.
