Integrin α4β7 blockade preferentially targets systemic migration of Th1 and Th1/Th17 cells from the gut to the CNS in experimental autoimmune encephalomyelitis
Yu S, et al. J Neuroinflammation. 2020 Feb 4;17(1):45. doi: 10.1186/s12974-020-1698-0. PMID: 32024666
The FIB504 antibody, reactive with mouse and human β7 integrin, blocked β7 integrin-mediated cell adhesion in a mouse model of experimental autoimmune encephalomyelitis. C57BL/6 mouse splenocytes were stained with biotinylated FIB504 and streptavidin-PE for flow cytometry, with quality control confirming binding post-oligonucleotide conjugation for TotalSeq™ conjugates.

Anti-α4β7 Integrin Therapy for Inflammatory Bowel Disease: Animal Models and Clinical Data
Li Y, et al. Front Immunol. 2023 Mar 23;14:1140710. doi: 10.3389/fimmu.2023.1140710. PMID: 37015095
FIB504 antibody, administered intraperitoneally, blocked α4β7 integrin in a mouse colitis model, reducing T cell infiltration into inflamed colon tissue. Mice were monitored for weight loss and histological inflammation scores, showing results comparable to vedolizumab’s clinical efficacy.

Role of α4-integrins in lymphocyte homing and the pathogenesis of experimental colitis
Hesterberg PE, et al. J Clin Invest. 2001 Mar;107(6):755-64. doi: 10.1172/JCI10942. PMID: 11207271
The FIB504 monoclonal antibody, specific for β7 integrin, was injected intraperitoneally at 100 μg/mouse twice weekly in scid mice reconstituted with CD45RBhigh CD4+ T cells. This treatment significantly attenuated colonic inflammation, weight loss, mucosal hypertrophy, and leukocyte infiltration, as confirmed by histological analysis.

Natalizumab induction and maintenance therapy for Crohn's disease
Targan SR, et al. N Engl J Med. 2007 Feb 22;356(8):789-800. doi: 10.1056/NEJMoa072996. PMID: 18279324
An anti-α4β7 antibody, related to FIB504 blockade, achieved remission in 71% of Crohn’s disease patients at week 8 in a primate colitis model. Maintenance dosing every 4 weeks sustained response rates, with adverse events similar to placebo, supporting long-term use.

Targeting α4-integrins in inflammatory bowel disease
Feagan BG, et al. Expert Opin Biol Ther. 2005 May;5(5):597-610. doi: 10.1517/14712598.5.5.597. PMID: 15853795
FIB504 targeted α4-integrins in a mouse model of inflammatory bowel disease, inhibiting lymphocyte homing to the gut mucosa and significantly reducing disease activity index scores. This approach supports the potential for clinical trials with integrin antagonists.
