Etrasimod for Immune Checkpoint Inhibitor Diarrhea and Colitis

Summary

This is a randomized, double-blind, placebo-controlled, two-arm phase 2 study of etrasimod plus corticosteroids versus placebo plus corticosteroids for the treatment of IMDC CTCAE v5.0 grade ≥ 2 due to ICI therapy alone (α-PD-(L)1 monotherapy or combined with another ICI, such as α-CTLA-4 or α-LAG-3) or ICI plus an oral tyrosine kinase inhibitor that in the opinion of the treating physician requires treatment with corticosteroid-based immunosuppression and does not require immediate secondary immune suppression, such as vedolizumab or infliximab (or equivalent). IMDC is one of the most common Immune Related Adverse Events (irAEs) from treatment with ICI. Current guidelines recommend steroid treatment for IMDC CTCAE grade ≥ 2, which requires temporary or permanent cessation of ICI therapy. Corticosteroids may interfere with the anti-tumor activity of ICIs and are therefore not co-administered. Strategies are needed to both reduce the dose and duration of corticosteroids needed for IMDC treatment and minimize the duration off ICI therapy before re-administering ICI (for those patients in whom it is deemed safe to rechallenge).
