Immunopharmacology Comments

Interaction of the lymphotoxin β receptor (LTBR) with its ligand is required for the development and organization of the secondary lymphoid organs and is involved in chemokine release (reported to induce interleukin 8 gene expression [2]). The LTBR pathway also drives expression of homeostatic chemokines (CCL19, CCL21, CXCL13) that are associated with the pathological development of ectopic lymphoid-like follicles in the exocrine glands of patients with Sjögren's syndrome. Consequently the CXCL13/LTBR axis is considered as a potential therapeutic target in conditions like Sjögren's syndrome. This is evidenced by the development of pharmaceutical agents that block LTBR activity being advanced to clinical trials (e.g. baminercept (BG9924; Biogen) which is a soluble LTBR-IgG Fc fusion protein [1]). BG9924, was primarily evaluated in clinical trials for active rheumatoid arthritis (RA; NCT00458861). However development in RA was terminated because interim analysis of trial data indicated that BG9924 therapy failed to meet the primary endpoint.
