Efficacy, Safety, and Pharmacodynamic Effects of the Bruton’s Tyrosine Kinase Inhibitor, Fenebrutinib (GDC-0853), in Moderate to Severe Systemic Lupus Erythematosus: Results of a Phase 2 Randomized Controlled Trial
Background/Purpose: Fenebrutinib (GDC-0853, FEN) is an oral, non-covalent, and highly selective inhibitor of Bruton’s tyrosine kinase (BTK) in clinical development for autoimmune diseases. The efficacy,…Abstract Number: 1906 • 2019 ACR/ARP Annual Meeting
Using Multi-modal Ultrasound to Assess Disease Activity Within the Salivary Glands of Patients with Primary Sjögren’s Syndrome Treated with Ianalumab (VAY736)
Background/Purpose: To use ultrasound (US) to demonstrate that ianalumab, a monoclonal antibody with dual mechanisms-of-action of BAFF:BAFF-R blockade and enhanced, ADCC-mediated B cell depletion, can…Abstract Number: L07 • 2018 ACR/ARHP Annual Meeting
VIB4920, a Novel, Engineered CD40L Antagonist Decreased Disease Activity and Improved Biomarkers of Immune Activation in Patients with Active Rheumatoid Arthritis in a Phase 1b, Multiple-Ascending Dose Proof-of-Concept Study
Background/Purpose: The CD40L/CD40 co-stimulatory pathway is important for T-cell-dependent antibody production and plays a central role in RA and other autoimmune diseases. VIB4920 (formerly MEDI4920)…Abstract Number: L14 • 2018 ACR/ARHP Annual Meeting
Top-Line Results of a Phase 2, Double-Blind, Randomized, Placebo-Controlled Study of a Reversible B Cell Inhibitor, XmAb®5871, in Systemic Lupus Erythematosus (SLE)
Background/Purpose: XmAb5871 is a humanized anti-CD19 antibody Fc-engineered for increased affinity to FcgRIIb. Co-ligation of CD19 and FcgRIIb inhibits B lineage cells key to SLE…Abstract Number: 5 • 2018 ACR/ARHP Annual Meeting
Short Chain Fatty Acid Acetate Induces Regulatory B Cells in Mice and Humans, Which Can Protect Against Arthritis
Background/Purpose: Autoimmunity and more broadly non-communicable diseases develop with the imbalance between anti- and pro-inflammatory immune cell subsets, leading to an uncontrolled and damaging inflammation.…Abstract Number: 1870 • 2018 ACR/ARHP Annual Meeting
Phase 2 Trial of Induction Therapy with Anti-CD20 (Rituximab) Followed By Maintenance Therapy with Anti-BAFF (Belimumab) in Patients with Active Lupus Nephritis
Background/Purpose: Two randomized, controlled trials of rituximab in patients with lupus and lupus nephritis (LN) did not meet their primary endpoints. A potential explanation is…Abstract Number: 2676 • 2018 ACR/ARHP Annual Meeting
SLE Patients with No Organ Damage Might Benefit More from Belimumab Treatment
Background/Purpose: In systemic lupus erythematosus (SLE), organ damage is associated with unfavourable disease courses and premature mortality. We aimed at investigating the impact of organ…Abstract Number: 2792 • 2018 ACR/ARHP Annual Meeting
The Effect of B Cell Targeted Therapies on Autoantibodies and Excessive Neutrophil Extracellular Trap Formation in Systemic Lupus Erythematosus
Background/Purpose: Systemic lupus erythematosus (SLE) is a severe systemic autoimmune disease characterized by immune-complexes (ICx) which cause inflammation and damage. Effective targeting of autoantibody secreting…Abstract Number: 20 • 2017 ACR/ARHP Annual Meeting
Low Molecular Weight BAFF Receptor Antagonists Restrain Infiltration of B Cells into Organs of Autoimmune Model Mice By Suppressing B Cell Activation
Background/Purpose: We have reported that soluble BAFF (sBAFF) robustly increased IL-6 production by peripheral monocytes of patients with primary Sjögren’s syndrome (pSS) and that the…Abstract Number: 25 • 2017 ACR/ARHP Annual Meeting
A Novel Role for Galectin-3 Binding Protein in B Cell Biology and Antibody Secretion
Background/Purpose: Antibodies are important in protection against pathogens, but also harbor the potential to cause autoimmune disease when directed against self-antigens. Systemic lupus erythematosus (SLE)…Abstract Number: 32 • 2017 ACR/ARHP Annual Meeting
Longitudinal Associations between Rheumatoid Factor and Ex Vivo Cytokine Production Reveal Novel Mechanistic Insights into Rheumatoid Arthritis
Background/Purpose: Positive rheumatoid factor (RF) and/or anti-citrullinated protein antibodies (ACPA) identify a major rheumatoid arthritis (RA) subgroup, characterized by greater propensity to erosive joint damage…Abstract Number: 514 • 2017 ACR/ARHP Annual Meeting
BMS-986195, a Novel, Rapidly Acting, Covalent Inhibitor of Bruton’s Tyrosine Kinase: Safety, Pharmacokinetic and Pharmacodynamic Profiles in Healthy Participants
Background/Purpose: Bruton’s tyrosine kinase (BTK) is an attractive, novel therapeutic target for autoimmune disease, as it is required for signal transduction and activation via B-cell…Abstract Number: 889 • 2017 ACR/ARHP Annual Meeting
Attainment of Low Disease Activity By Patients with Systemic Lupus Erythematosus Starting with High Disease Activity in a 24-Week, Randomized, Placebo-Controlled, Phase IIb Study of Atacicept (ADDRESS II)
Background/Purpose: Low disease activity (LDA) in lupus patients is increasingly a goal of treatment. For instance, Lupus Low Disease Activity State (LLDAS) attainment is associated…Abstract Number: 890 • 2017 ACR/ARHP Annual Meeting
Synergetic B-Cell Immunomodulation with Rituximab and Belimumab Combination Treatment in Severe, Refractory SLE
Background/Purpose: Neutrophil extracellular traps (NETs) are auto-antigenic DNA strands and potentially give rise to SLE-specific autoantibodies that can deposit in glomeruli. It has been shown…
