Cenerimod (DB12705): A Comprehensive Monograph on a Novel S1P1 Receptor Modulator for Systemic Lupus Erythematosus

Executive Summary

Cenerimod is an investigational, first-in-class, orally administered small molecule being developed for the treatment of Systemic Lupus Erythematosus (SLE).[1] It functions as a highly potent and selective modulator of the sphingosine-1-phosphate receptor subtype 1 (

S1P1​), a validated therapeutic target for controlling lymphocyte trafficking in autoimmune diseases.[3] With a high functional potency (half-maximal effective concentration,

EC50​, of approximately 1–2.7 nM), Cenerimod's primary mechanism involves inducing the internalization of S1P1​ receptors on lymphocytes, which sequesters these pathogenic immune cells within secondary lymphoid organs and prevents their migration to sites of inflammation.[2]

The pharmacological profile of Cenerimod is distinguished by its unique signaling properties and exceptional selectivity, which contribute to a potentially superior safety profile compared to less selective agents in its class.[3] Its pharmacokinetic (PK) profile is characterized by a cytochrome P450 (CYP) enzyme-independent metabolism, minimizing the potential for drug-drug interactions, and an unusually long terminal half-life.[6] This long half-life results in a gradual accumulation to steady-state, creating a "built-in up-titration" effect that naturally mitigates the acute, first-dose cardiac effects commonly associated with

S1P receptor modulators.[6]
