REGN-1400 is a humanized monoclonal antibody inhibitor targeting ErbB3. REGN-1400 reduces tumor cell proliferation by inhibiting ErbB3 and blocking related signaling pathways. REGN-1400 is promising for research of solid tumors such as non-small cell lung cancer (NSCLC), colorectal cancer (CRC), and squamous cell carcinoma of the head and neck (SCCHN) [1].
