CCL2 is implicated in the pathogenesis of certain inflammatory diseases and cancer. Binding of CCL2 to its receptor CCR2 triggers calcium mobilization and chemotaxis. CNTO 888 is a neutralizing anti-CCL2 antibody that binds human CCL2 with high affinity of Kd=22pM and inhibits CCL2 binding to its receptor. The systemic administration of anti-CCL2 neutralizing antibodies (CNTO888 and C1142) significantly retarded tumor growth and attenuated CD68+ macrophage infiltration, which was accompanied by a significant decrease in microvascular density (PMID: 17710158). Phase 1 trials in 44 patients with solid tumors concluded that CNTO888 was well tolerated in individuals with evidence of transient free CCL2 suppression and preliminary antitumor activity (PMID: 23385782). This antibody was also capable of inhibiting growth of breast cancer when administered individually or as a cocktail (Campion et al, 2009). A phase 2 study in 46 patients with castration-resistant prostate cancer (CRPC) concluded that carlumab was well-tolerated but did not block the CCL2/CCR2 axis or show antitumor activity as a single agent in metastatic CRPC (PMID: 22907596).
