A Pilot Study of CC-220 to Treat Systemic Lupus Erythematosus.

Celgene42 enrolled

Overview

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.

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 Outcomes

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.

Time frame: 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.

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.

Time frame: 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 Outcomes

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.

Time frame: 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.

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.

Time frame: 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.

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.

Time frame: 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.

Terminal Phase Half-Life (T1/2) Of Iberdomide

Terminal phase half-life in plasma, calculated as \[(In 2)/λz\]. T1/2 half was only calculated when a reliable estimate for λz 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.

Time frame: 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.

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.
