Overview
11 DESCRIPTION PONVORY (ponesimod) is a sphingosine 1-phosphate receptor modulator. The chemical name for ponesimod is (2Z,5Z)-5-[3-chloro-4-[(2 R )-2,3- dihydroxypropoxy]benzylidene]-3-(2-methylphenyl)-2-(propylimino)-1,3-thiazolidin-4-one. It has one chiral center with absolute configuration of (R) . Its molecular formula is C 23 H 25 ClN 2 O 4 S and its molecular weight is 460.97 g/mol.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Ponesimod is a S1P receptor 1 modulator that binds with high affinity to S1P receptor 1. Ponesimod blocks the capacity of lymphocytes to egress from lymph nodes, reducing the number of lymphocytes in peripheral blood. The mechanism by which ponesimod exerts therapeutic effects in MS is unknown, but may involve reduction of lymphocyte migration into the central nervous system. 12.2 Pharmacodynamics Immune System In healthy volunteers, PONVORY induces a dose-dependent reduction of the peripheral blood lymphocyte count from a single dose of 5 mg onwards, with the greatest reduction observed 6 hours post-dose, caused by reversible sequestration of lymphocytes in lymphoid tissues.
