Petosemtamab (MCLA 158) is a highly potent monoclonal antibody against EGFR (Kd: 0.22 nM) and LGR5 (Kd: 0.86 nM). Petosemtamab promotes EGFR signaling disruption and receptor breakdown in LGR5+ cancer cells. Petosemtamab can be used in the study of solid tumors such as head and neck squamous cell carcinoma (HNSCC) and metastatic colorectal cancer (CRC).

| Targets & IC50 | EGFR:0.22 nM (Kd), LGR5:0.85 nM (Kd) |
| In vitro | Treatment with MCLA-158(Petosemtamab) (1 µg/mL; 24 or 72 hours) induces the degradation of EGFR in EGFR+/LGR5+ colorectal cancer organoids[2]. |
| In vivo | Treatment with MCLA-158(Petosemtamab) (25 mg/kg/week, intravenous injection, for 6 weeks) leads to tumor regression in esophageal squamous cell carcinoma, gastric adenocarcinoma, and head and neck PDX models[2]. |
