Ozanimod (RPC1063) is a specific and potent small molecule modulator of the
sphingosine 1-phosphate receptor 1 (S1PR1) and receptor 5 (S1PR5), which has
shown therapeutic benefit in clinical trials of relapsing multiple sclerosis and
ulcerative colitis. Ozanimod and its active metabolite, RP-101075, exhibit a
similar specificity profile at the S1P receptor family in vitro and
pharmacodynamic profile in vivo. The NZBWF1 mouse model was used in therapeutic
dosing mode to assess the potential benefit of ozanimod and RP-101075 in an
established animal model of systemic lupus erythematosus. Compared with
vehicle-treated animals, ozanimod and RP-101075 reduced proteinuria over the
duration of the study and serum blood urea nitrogen at termination. Additionally,
ozanimod and RP-101075 reduced kidney disease in a dose-dependent manner, as
measured by histological assessment of mesangial expansion, endo- and
exo-capillary proliferation, interstitial infiltrates and fibrosis, glomerular
deposits, and tubular atrophy. Further exploration into gene expression changes
in the kidney demonstrate that RP-101075 also significantly reduced expression of
fibrotic and immune-related genes in the kidneys. Of note, RP-101075 lowered the
number of plasmacytoid dendritic cells, a major source of interferon alpha in
lupus patients, and reduced all B and T cell subsets in the spleen. Given the
efficacy demonstrated by ozanimod and its metabolite RP-101075 in the NZBWF1
preclinical animal model, ozanimod may warrant clinical evaluation as a potential
treatment for systemic lupus erythematosus.
