Etrasimod, sold under the brand name Velsipity, is a medication that is used for the treatment of ulcerative colitis (UC).[1] It is a selective sphingosine-1-phosphate (S1P) receptor modulator that modifies the activity of the immune system.[1] It is taken by mouth.[1]
Etrasimod was discovered by Arena Pharmaceuticals, with subsequent development by Pfizer.[2]
Etrasimod is a synthetic next-generation selective Sphingosine 1-phosphate (S1P) receptor modulator that targets the S1P1,4,5 with no detectable activity on S1P2 and S1P3 receptors. S1P receptors are membrane-derived lysophospholipid signaling molecules that are involved in the sequestration of circulating peripheral lymphocytes in lymph nodes.1 Therefore, S1P receptor modulators like etrasimod were investigated in treating immune-mediated diseases like ulcerative colitis where a high level of inflammatory T cells is present in the gastrointestinal tract, thus causing diffuse mucosal inflammation.1 In fact, it has been observed that antigen-activated T cells within peripheral lymphoid organs can transiently downregulate S1P receptor levels to facilitate immune cells trafficking into the intestinal mucosa.2
Etrasimod was approved on October 13, 2023, by the FDA under the brand name VELSIPITY for the treatment of adults with moderately to severely active ulcerative colitis. This approval was based on favorable results obtained from Pfizer’s Elevate UC Phase III registrational program, consisting of the Elevate UC 52 and Elevate UC 12 clinical trials, that investigates the efficacy of a 2-mg daily dose regimen of etrasimod, with a 32% and 26% remission rate observed in UC 52 and UC 12 trials respectively.4
Medical uses
Etrasimod is used for the treatment of moderate to severe ulcerative colitis.[1]
Mechanism of action
It works by causing T cells to become trapped in the lymph nodes, preventing them from entering the bloodstream, from where they would travel to other tissues in the body and mediate inflammation.[3][4][5][6][7][8]
Society and culture
Legal status
Velsipity was approved by the US Food and Drug Administration (FDA) in October 2023.[1][9][10]
Names
Etrasimod is the international nonproprietary name.[11]

APD334 was discovered as part of our internal effort to identify potent, centrally available, functional antagonists of the S1P1 receptor for use as next generation therapeutics for treating multiple sclerosis (MS) and other autoimmune diseases. APD334 is a potent functional antagonist of S1P1 and has a favorable PK/PD profile, producing robust lymphocyte lowering at relatively low plasma concentrations in several preclinical species. This new agent was efficacious in a mouse experimental autoimmune encephalomyelitis (EAE) model of MS and a rat collagen induced arthritis (CIA) model and was found to have appreciable central exposure.
APD334 is the second eluting enantiomer (most retained) with a retention time of 48.4 minutes. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.54-1.75 (m, 4H), 1.79-1.92 (m, 2H), 1.95-2.16 (m, 3H), 2.39 (dd, J = 16.0, 8.8 Hz, 1H), 2.61-2.83 (m, 4H), 3.23-3.34 (m, 1H), 3.45-3.56 (m, 1H), 5.14 (s, 2H), 6.74 (dd, J = 8.7, 2.4 Hz, 1H), 6.92 (d, J = 2.3 Hz, 1H), 7.24 (d, J = 8.8 Hz, 1H), 7.64 (d, J = 8.1 Hz, 1H), 7.72 (d, J = 8.6 Hz, 1H), 7.74 (s, 1H), 10.50 (s, 1H), 12.24 (bs, 1H). 13C APT NMR (100 MHz, DMSO-d6): δ up (C, CH2): 23.1, 25.5, 35.5, 35.6, 68.6, 117.0, 124.7 (q, J = 273 Hz), 124.2, 126.8 (q, J = 28 Hz), 128.7, 136.1, 136.2, 144.6, 147.0, 151.9, 173.4; down (CH, CH3): 35.0, 40.5, 102.1, 110.0, 112.4, 124.1 (q, J = 5.7 Hz), 128.4, 131.7. 19F NMR (400 MHz, DMSO-d6) δ ppm -57.4.
