Cenicriviroc (CVC) is an orally active antagonist of ligand binding to C-C chemokine receptor type 5 (CCR5) and C-C chemokine receptor type 2 (CCR2). CVC blocks the binding of RANTES, MIP-1a, and MIP-1ß to CCR5, and of MCP-1/CCL2 to CCR2. Methods of treating fibrosis and related conditions comprising co-administration of CVC with chemokine antagonists, FXR agonists, high dose vitamin E (>; 400 iU/d), a peroxisome proliferator-activated receptor alpha (PPAR-a) agonist, PPAR-? agonist, and/or PPAR-d agonist are provided herein.
