CD200R agonist (ARQ-234)

Overview

ARQ-234 is currently in preclinical development.

ARQ-234 is a fusion protein that serves as an agonist with high selectivity and potency for the CD200 receptor (CD200R).1

Atopic dermatitis 

CD200R in atopic dermatitis.

Clinical landscape

  • Atopic dermatitis is a common, chronic inflammatory skin disease affecting both children and adults2
  • Itch is the most burdensome symptom, causing patients to experience substantially reduced quality of life and sleep disturbances3
  • The skin barrier is typically compromised in atopic dermatitis4
  • Topical corticosteroids and emollients are the standard of care4
  • Steroids are not suitable for long-term use, and children are at risk of greater systemic absorption4

Proposed MOA

  • CD200R is expressed by cells involved in type 2 inflammation5
  • CD200R agonists activate the pathway that regulates immune cell activation1
  • ARQ-234 binds to CD200R, inducing inhibitory signaling on immune cells that regulate inflammation1
