Clinical Trial Summary

The purpose of this study is to determine whether CC-220 is effective for the treatment of skin, joint and serological manifestations of systemic lupus erythematosus.

Description:

The study consists of 2 parts. Part 1 is a randomized, double-blind, placebo controlled, ascending dose study to evaluate the safety and tolerability of CC-220 in SLE subjects.

Subject participation in Part 1 consists of 3 phases:

• Pre-treatment Screening Phase: up to 28 days prior to the first dose of the investigational product (IP)

• Treatment Phase: up to 84 days

• Observation Phase: 84 day post-treatment A total of approximately 40 subjects will be randomized into 4 dose groups with a 4:1 ratio of CC-220 (0.3 mg every other day [QOD], 0.3 mg everyday [QD], 0.6 mg and 0.3 mg on alternating days, and 0.6 mg QD) or matching placebo. In each dosing arm, 8 subjects will receive active drug and 2 subjects will receive placebo. The Treatment Phase will be up to 84 days in duration for all dose groups. Subjects who discontinue IP early and all subjects who complete the 84 day treatment phase will enter into the Observational Follow-up Phase for an 84 day period. A subject will be permitted to reduce their dose one time during Part 1 of the study.

Part 2 is the Active Treatment Extension Phase (ATEP) which is an extension to evaluate the long-term efficacy and safety/tolerability of CC-220 in SLE subjects who completed Part 1 of the study. Subjects who complete the Treatment Phase of Part 1 of the study will be eligible to receive CC-220 in the ATEP for up to 2 years. All subjects who participate in the ATEP will receive either 0.3 mg QD or 0.6 mg and 0.3 mg QD on alternating days. Subjects who terminate the Treatment Phase of Part 1 early will not be eligible for entry into the ATEP.

Subject participation consists of two phases:

• Active Treatment Extension Phase: Up to 2 years

• Observational Follow-up Phase: One month

Primary	Number of Participants With Treatment Emergent Adverse Events (TEAEs) in Part 1 Treatment Phase	A TEAE was defined as any adverse event (AE) that began or worsened on or after the start of IP up to 28 days after the last dose of IP or IP discontinuation date, whichever was later. Each participant was counted once for each applicable category. An IP-related TEAE was defined as a TEAE that the investigator considered to be of suspected relationship to IP. The severity of each adverse event and serious AE (SAE) was assessed by the investigator and graded based on a scale from mild - mild symptoms to severe AEs (non-serious or serious). A serious adverse event (SAE) was any AE which: • Resulted in death • Was life-threatening • Required inpatient hospitalization or prolongation of existing hospitalization • Resulted in persistent or significant disability/incapacity • Was a congenital anomaly/birth defect • Constituted an important medical event.	From the start of the first dose of IP until 28 days after the last dose or study discontinuation in Part 1; median treatment duration = 12.0 weeks for the placebo, 0.3 mg QOD and 0.3 mg iberdomide QD arms, 11.9 weeks for the 0.6/0.3 ALT and 0.6 cohorts.
Primary	Number of Participants With Treatment Emergent Adverse Events (TEAEs) in the Active Treatment Extension Phase	A TEAE was defined as any adverse event (AE) that began or worsened on or after the start of IP through 28 days after the last dose of IP or IP discontinuation date, whichever was later. Each participant was counted once for each applicable category. An IP-related TEAE was defined as a TEAE that the investigator considered to be of suspected relationship to IP. The severity of each adverse event and serious AE (SAE) was assessed by the investigator and graded based on a scale from mild - mild symptoms to severe AEs (non-serious or serious). A serious adverse event (SAE) was any AE which: • Resulted in death • Was life-threatening • Required inpatient hospitalization or prolongation of existing hospitalization • Resulted in persistent or significant disability/incapacity • Was a congenital anomaly/birth defect • Constituted an important medical event.	From the date of the first dose of IP in the ATEP until 28 days after the last dose in the ATEP or study discontinuation; median duration of IP was 95.86 weeks for the 0.3 mg iberdomide QD cohort and 60.64 weeks for the 0.6 mg/0.3 mg ALT QD cohorts.
Secondary	Area Under the Plasma Concentration-Time Curve From Time 0 to the Last Measurable Concentration (AUCt) of Iberdomide	The area under the plasma concentration time curve (AUCt) was defined as area under the concentration-time curve from time zero to the last quantifiable time point, calculated by the linear trapezoidal rule when concentrations are increasing and the logarithmic trapezoidal method when concentrations are decreasing. Single and multiple-dose PK were collected in Part 1 of the study for all dose groups. Iberdomide reaches steady state within 7 days. PK collection on Day 29 was sufficient to understand PK once steady state was reached. As no dose adjustments were made in ATEP, further PK collection was not needed.	Pharmacokinetic (PK) blood samples were collected on Day 1 and Day 29 pre-dose (Time = 0 hours) and at 1, 2, 3, 4, between 6 and 8 hours and 24 hours after administration of IP.
Secondary	Maximum Observed Concentration (Cmax) Of Iberdomide	Maximum observed plasma concentration, obtained directly from the observed concentration versus time data. Single and multiple-dose PK were collected in Part 1 of the study for all dose groups. Iberdomide reaches steady state within 7 days. PK collection on Day 29 was sufficient to understand PK once steady state was reached. As no dose adjustments were made in ATEP, further PK collection was not needed.	Pharmacokinetic blood samples were collected on Day 1 and Day 29 at pre-dose (Time = 0 hours) and at 1, 2, 3, 4, between 6 and 8 hours and 24 hours after administration of IP.
Secondary	Time to Reach Maximum Concentration (Tmax) of Iberdomide	Time to Cmax, obtained directly from the observed concentration versus time data. Single and multiple-dose PK were collected in Part 1 of the study for all dose groups. Iberdomide reaches steady state within 7 days. PK collection on Day 29 was sufficient to understand PK once steady state was reached. As no dose adjustments were made in ATEP, further PK collection was not needed.	Pharmacokinetic blood samples were collected on Day 1 and Day 29 at pre-dose (Time = 0 hours) and at 1, 2, 3, 4, between 6 and 8 hours and 24 hours after administration of IP.
Secondary	Terminal Phase Half-Life (T1/2) Of Iberdomide	Terminal phase half-life in plasma, calculated as [(In 2)/?z]. T1/2 half was only calculated when a reliable estimate for ?z could be obtained. Single and multiple-dose PK were collected in Part 1 of the study for all dose groups. Iberdomide reaches steady state within 7 days. PK collection on Day 29 was sufficient to understand PK once steady state was reached. As no dose adjustments were made in ATEP, further PK collection was not needed.	Pharmacokinetic blood samples were collected on Day 1 and Day 29 at pre-dose (Time = 0 hours) and at 1, 2, 3, 4, between 6 and 8 hours and 24 hours after administration of IP.
Secondary	Percentage of Participants Who Achieved =4 Points Reduction From Baseline in Hybrid Safety of Estrogens in Systemic Lupus Erythematosus National Assessment SLE Disease Activity Index Score (SELENA SLEDAI) During the ATEP by Time Point	The SELENA SLEDAI score measures SLE disease activity through assessment of 24 lupus descriptors/manifestations. Each descriptor (clinical or lab values) receives a positive score if it is present over the previous assessment period; a score of '0' indicates inactive disease while a positive score (from 1 to 8 based on the relative importance of each descriptor in the total scoring) indicates disease activity. The SELENA SLEDAI score is the sum of all 24 descriptors' scores for the assessment period. The SELENA SLEDAI score can range from '0' (no SLE disease activity) to a maximum theoretical score of 105 (maximum SLE disease activity). The higher the SELENA SLEDAI score the greater of SLE disease activity.	Baseline to Weeks 1, 4, 12, 24, 36, 48, 60, 72, 84, 96 and follow-up at Week 100 during the ATEP.
Secondary	Change From Baseline in the Hybrid Systemic Lupus Erythematosus Disease Activity Index (SELENA SLEDAI) During the ATEP by Time Point	The SELENA SLEDAI score measures SLE disease activity through assessment of 24 lupus descriptors/manifestations. Each descriptor (clinical or lab values) receives a positive score if it is present over the previous assessment period; a score of '0' indicates inactive disease while a positive score (from 1 to 8 based on the relative importance of each descriptor in the total scoring) indicates disease activity. The SELENA SLEDAI score is the sum of all 24 descriptors' scores for the assessment period. The SELENA SLEDAI score can range from '0' (no SLE disease activity) to a maximum theoretical score of 105 (maximum SLE disease activity). The higher the SELENA SLEDAI score the greater of SLE disease activity.	Baseline to Weeks 1, 4, 12, 24, 36, 48, 60, 72, 84, 96 and follow-up at Week 100 during the ATEP.
Secondary	Change From Baseline in Swollen Joint Count During the ATEP by Time Point	Joint swelling was noted as present or absent. Forty-four joints were assessed for swelling, including the sternoclavicular, acromioclavicular, shoulder, elbow, wrist, metacarpophalangeal (MCP), proximal interphalangeal (PIP), knee, ankle, and metatarsophalangeal (MTP) joints were included in this joint count.	Baseline to Weeks 1, 4, 12, 24, 36, 48, 60, 72, 84, 96 and follow-up at Week 100 during the ATEP.
Secondary	Change From Baseline in Tender Joint Count During the ATEP by Time Point	Joint tenderness was noted as present or absent. Forty-four joints were assessed for swelling, including the sternoclavicular, acromioclavicular, shoulder, elbow, wrist, metacarpophalangeal (MCP), proximal interphalangeal (PIP), knee, ankle, and metatarsophalangeal (MTP) joints were included in this joint count.	Baseline to Weeks 1, 4, 12, 24, 36, 48, 60, 72, 84, 96 and follow-up at Week 100 during the ATEP.
Secondary	Percent Change From Baseline in Cutaneous Lupus Area and Severity Index (CLASI) Activity Score During the ATEP by Time Point	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 nonscarring alopecia is scored on a scale of 0 (absent) to 3 (focal or patchy in more than one quadrant). To calculate the CLASI activity score, all scores for erythema, scale/hypertrophy, mucous membrane lesions and alopecia are added together. Composite scores are calculated by summing the individual component scores. The higher the score, the greater the cutaneous disease activity.	Baseline to Weeks 1, 4, 12, 24, 36, 48, 60, 72, 84, 96 and follow-up at Week 100 during the ATEP.
Secondary	Change From Baseline in the Physician's Global Assessment (PGA) Score During the ATEP by Time Point	The physician's global assessment was administered by the treating physician and was used to gauge the participants overall state of health. The instrument uses a visual analogue 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; 3 = severe disease	Baseline to Weeks 1, 4, 12, 24, 36, 48, 60, 72, 84, 96 and follow-up at Week 100 during the ATEP.
Secondary	Change From Baseline in the British Isles Lupus Assessment Group (BILAG) 2004 Global Score During the ATEP by Time Point	The BILAG-2004 index measures clinical disease activity in systemic lupus erythematosus (SLE). A single alphabetic score (A through E) is used to denote disease severity for each of the 9 domains (constitutional, mucocutaneous, neuropsychiatric, musculoskeletal, cardiorespiratory, gastrointestinal, ophthalmic, renal, and hematologic). BILAG A represents the most active disease or severe disease; BILAG B represents intermediate activity or moderate disease; BILAG C represents stable mild disease; BILAG D represents organ system previously affected but now inactive; and BILAG E represents organ system never involved. The global BILAG score is the sum of a converted numerical score (A=9, B=3, C=1, D=0, E=0) over 9 domains. The theoretical range spans from 0 (no activity) to 13 active or severe disease activity BILAG. A higher score means more severe disease activity while a lower score means lower disease activity (or no disease activity for score of zero).	Baseline to Weeks 1, 4, 12, 24, 36, 48, 60, 72, 84, 96 and follow-up at Week 100 during the ATEP.
Secondary	Change From Baseline in the Pericardial/Pleuritic Pain Scale During ATEP by Time Poimt	The pericardial/pleuritic pain scale was scored using numerical values of 1 through 10 with 1 representing 'no pain' and 10 representing 'worst possible pain'. These were self-administered by the participants and gauged the severity of their SLE pain related to pericardial and pleuritic discomfort. Any indication from participants or study assessments, aside from pain, which indicated clinically significant pericardial or pleuritic manifestations of SLE was thoroughly investigated; if clinically significant SLE related complications were found, the participants was to be discontinued from the study and entered into the Observational Follow-up Period and treated appropriately.	Baseline to Weeks 1, 4, 12, 24, 36, 48, 60, 72, 84, 96 and follow-up at Week 100 during the ATEP.
Secondary	Change From Baseline in the Fatigue Visual Analog Scale (VAS) During the ATEP by Time Point	The Fatigue VAS evaluates SLE-related fatigue using a 0 to 100 mm VAS scale. The Fatigue VAS allowed the participant to indicate the degree of SLE-related fatigue by placing an "X" representing how they feel, along a visual analog line that extends between two extremes (e.g., from not at all tired to extremely tired) over the previous week. A decrease in the fatigue VAS indicates improvement.	Baseline to Weeks 1, 4, 12, 24, 36, 48, 60, 72, 84, 96 and follow-up at Week 100 during the ATEP.
Secondary	Change From Baseline in the Cutaneous Lupus Area and Severity Index (CLASI) Damage Score During the ATEP by Time Point	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 nonscarring alopecia is scored on a scale of 0 (absent) to 3 (focal or patchy in more than one quadrant). To calculate the CLASI activity score, all scores for erythema, scale/hypertrophy, mucous membrane lesions and alopecia are added together. Composite scores are calculated by summing the individual component scores. The higher the score, the greater the cutaneous disease activity.	Baseline to Weeks 1, 4, 12, 24, 36, 48, 60, 72, 84, 96 and follow-up at Week 100 during the ATEP.
Secondary	Change From Baseline in the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Systemic Lupus Erythematosus (SLICC/ACR SLE) Damage Index Score During the ATEP by Time Point	SLICC/ACR score or damage index is a measure of cumulative damage due to Systemic Lupus Erythematosus (SLE). Damage is defined as nonreversible change (not related to active inflammation) occurring since onset of lupus, ascertained by clinical assessment and present for at least 6 months. Damage is defined for 12 separate organ systems: ocular (range 0-2), neuropsychiatric (0-6), renal (0-3), pulmonary (0-5), cardiovascular (0-6), peripheral vascular (0-5), gastrointestinal (0-6), musculoskeletal (0-7), skin (0-3), endocrine (diabetes) (0-1), gonadal (0-1) and malignancies (0-2). A score of 0=no damage, early damage is defined as =1. The total maximum score is 47, and increasing score indicates increasing disease damage severity.	Baseline to Weeks 1, 4, 12, 24, 36, 48, 60, 72, 84, 96 and follow-up at Week 100 during the ATEP.
