SEATTLE--(BUSINESS WIRE)--Alpine Immune Sciences, Inc. (NASDAQ: ALPN), a leading clinical-stage immunotherapy company focused on developing innovative treatments for autoimmune and inflammatory diseases, announced today that the Company presented new translational data for acazicolcept (ALPN-101) in systemic lupus erythematosus (SLE) at the American College of Rheumatology Convergence 2023, November 10-15, 2023.
Acazicolcept Presentation Highlights Include:
- Acazicolcept target-related genes (ICOS, CD80, CD86) are upregulated in the T and B cells of SLE patients compared to healthy adults.
- Acazicolcept suppresses expression of genes associated with T cell activation and/or implicated in the pathogenesis of SLE more potently than inhibitors of the CD28 or ICOS pathways.
- Acazicolcept reduces pathogenic hypergammaglobulinemia and glomerular IgG deposition in a mouse model of lupus.
“These data reinforce the importance of multiple key pathways in the pathogenesis of SLE and further support the potential for acazicolcept, a first-in-class molecule, in its treatment,” said Stanford Peng, M.D., Ph.D., President and Head of Research and Development at Alpine. “Because CD28 and ICOS are closely related receptors that can both mediate T cell costimulation, inhibition of both may be required to provide optional outcomes in multiple autoimmune diseases. Clinical investigation of acazicolcept for the treatment of SLE, such as in our ongoing phase 2 study, Synergy, continues to be supported.”

About Acazicolcept (ALPN-101)
Acazicolcept (ALPN-101) is a first-in-class, dual inhibitor of the CD28 and ICOS T-cell costimulatory pathways being developed for treatment of systemic lupus erythematosus (SLE). By simultaneously blocking two key costimulatory pathways, acazicolcept has the potential to improve outcomes in patients suffering from severe autoimmune/inflammatory diseases. Preclinical studies have demonstrated efficacy in models of SLE, Sjögren’s syndrome, arthritis, inflammatory bowel disease, multiple sclerosis, type 1 diabetes, uveitis, and graft versus host disease.
