Brief Summary:

The purpose of this Phase 2, multicenter, randomized, placebo-controlled, double-blind study to evaluate the efficacy and safety of an oral treatment regimen of CC-220 versus placebo in adult subjects with active systemic lupus erythematosus.

Approximately 280 subjects with a documented diagnosis of SLE will be randomized 2:2:1:2 to receive CC-220 (0.45 mg QD, 0.3 mg QD or 0.15 mg QD) or identically appearing placebo.


Condition or disease Intervention/treatment Phase
Lupus Erythematosus, Systemic Drug: CC-220 Other: Placebo Phase 2

Detailed Description:

The study consists of four phases:

  • 4-week Screening Phase
  • 24-week placebo-controlled phase Subjects will receive either 0.45 mg QD, 0.3 mg QD, 0.15 mg QD or placebo for the first 24 weeks of treatment.
  • 28-week active treatment phase At Week 24, all subjects on placebo will be re-randomized to active treatment.
  • 52-week long-term extension phase Subjects who complete the treatment phase may be eligible to roll over into a Long-term Extension of up to 52 weeks of treatment.
  • 4 - 12-week observational follow-up All subjects who complete 52 weeks of treatment or discontinue the study early will enter a post-treatment observation follow-up phase. The Observational Follow-up Phase will consist of one visit 4 weeks following cessation of study drug for all subjects with an additional 12-week Observational Follow-up visit for males only.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Participants Who Achieve SLE Responder Index (SRI) (4) Response [ Time Frame: Week 24 ]

    The primary objective is to evaluate the clinical efficacy of three doses of CC-220 (0.45 mg once per day [QD], 0.3 mg QD or 0.15 mg QD) compared to placebo, for the treatment of active systemic lupus erythematosus (SLE) using the SLE Responder Index at Week 24

    Composite endpoint SRI(4), defined by the following criteria:

    • Reduction from Baseline of ≥ 4 points in the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) 2K score and
    • No new one or more British Isles Lupus Assessment Group (BILAG) A or new (excludes A to B) 2 or more BILAG B items compared to Baseline using BILAG 2004 Index and
    • No worsening from Baseline defined by an increase of < 0.30 points from Baseline on a Physician's Global Assessment (PGA) visual analog scale (VAS) from 0-3


Secondary Outcome Measures :
  1. Number of Participants With SLEDAI 2K Score Improvement of ≥ 4 Points From Baseline [ Time Frame: Week 24 ]
    The SLEDAI 2K score measures disease activity through assessment of 24 lupus manifestations using a weighted score of 1 to 8 points. A manifestation is recorded if it is present over the previous 30 days regardless of severity or whether it has improved or worsened. A SLEDAI 2K score of 3 to 4 points is representative of active disease and a decrease of 1 to 2 points is considered clinically meaningful.

  2. Number of Participants With a ≥ 50% Reduction in Cutaneous Lupus Area and Severity Index (CLASI) Activity Score From Baseline, in Participants With Baseline CLASI Activity Score ≥ 10 [ Time Frame: Week 24 ]
    The CLASI Activity Score ranges from 0 to 70. To generate the activity score erythema is scored on a scale of 0 (absent) to 3 (dark red; purple/violaceous/crusted/hemorrhagic) and scale/hypertrophy are scored on a scale of 0 (absent) to 2 (verrucous/hypertrophic). Both the erythema and scale/hypertrophy scores are assessed in 13 different anatomical locations. In addition, the presence of mucous membrane lesions is scored on a scale of 0 (absent) to 1 (lesion or ulceration), the occurrence of recent hair loss is captured (1=yes; 0=no) and non-scarring alopecia is scored on a scale of 0 (absent) to 3 (focal or patchy in more than one quadrant). To calculate the activity score, all scores for erythema, scale/hypertrophy, mucous membrane lesions and alopecia are added together.

  3. Number of Participants With no New Organ System Affected as Defined by 1 or More BILAG A or New (Excludes A to B) 2 or More BILAG B Items Compared to Baseline Using BILAG 2004 Index [ Time Frame: Week 24 ]
    The BILAG 2004 is a composite index that is based on the Classic BILAG index. It is a clinical measure of lupus disease activity. This tool assesses the changing severity of clinical manifestations of SLE using an ordinal scale scoring system that contain 9 systems (constitutional, mucocutaneous, neuropsychiatric, musculoskeletal, cardiorespiratory, gastrointestinal, ophthalmic, renal and hematological). Activity in each organ system is scored as: A=most active disease; B=intermediate activity; C=mild, stable disease; D=previous involvement, currently inactive; E=no previous activity.

  4. Percentage of Participants With no Worsening (Increase of < 0.30 Points From Baseline) in PGA Compared to Baseline [ Time Frame: Week 24 ]
    The PGA uses a visual analog scale with scores between 0 and 3 to indicate worsening of disease. The scoring is as follows: 0 = none, 1 = mild disease, 2 = moderate disease, and 3 = severe disease.

  5. Mean Change From Baseline in Swollen Joint Count in Participants With ≥ 2 Swollen Joints at Baseline [ Time Frame: Week 24 ]

    Joint tenderness and swelling will be noted as "present" or "absent," with no quantitation of severity using a 28- joint count.

    Note: Data presented is Adjusted mean data.


  6. Mean Change From Baseline in Tender Joint Count in Participants With ≥ 2 Tender Joints at Baseline [ Time Frame: Week 24 ]

    Joint tenderness and swelling will be noted as "present" or "absent," with no quantitation of severity using a 28- joint count.

    Note: Data presented is Adjusted mean data.


  7. Mean Change From Baseline in PGA Score [ Time Frame: Week 24 ]
    The PGA uses a visual analog scale with scores between 0 and 3 to indicate worsening of disease. The scoring is as follows: 0 = none, 1 = mild disease, 2 = moderate disease, and 3 = severe disease.

  8. Change From Baseline in Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue Score [ Time Frame: Week 24 ]

    The FACIT-Fatigue scale is a 13-item self-administered questionnaire that assesses both the physical and functional consequences of fatigue. Each question is answered on a 5-point scale, where 0 means "not at all," and 4 means "very much." The total FACIT-Fatigue score ranges from 0 to 52.

    Note: Data presented is Adjusted mean data.


  9. Percentage of Participants With Corticosteroid Reduction [ Time Frame: Week 24 ]
    • The percentage of participants with a prednisone or equivalent dose of ≥ 10 mg/day at Baseline whose prednisone or equivalent dose has been reduced to ≤ 7.5 mg/day by Week 16 and maintained through Week 24 with no flares between Week 16 and Week 24
    • The percentage of participants with a prednisone or equivalent dose of ≥ 10 mg/day at Baseline whose prednisone or equivalent dose has been reduced to < 10 mg/day by Week 16 and maintained through Week 24 with no flares between Week 16 and Week 24

  10. Percent Change From Baseline in Corticosteroid Reduction [ Time Frame: Week 24 ]

    Percent change from Baseline in oral corticosteroid (OCS) dose in subjects with prednisone or equivalent ≥ 10 mg/day at Baseline

    Note: Data presented is Adjusted mean data.


  11. The Total Corticosteroid Dose From Baseline Through Week 24 [ Time Frame: Through Week 24 ]
    Standardized total oral corticosteroid (OCS) dose.

  12. Number of Participants With Treatment-Emergent Adverse Events (TEAEs) [ Time Frame: from first dose to 28 days post-last dose through Week 24 (placebo-controlled phase), approximately 28 weeks total ]
    Number of participants who experienced a TEAE during the course of the study
