PROBLEM TO BE SOLVED: To provide a therapeutic composition for non-small cell lung cancer in a patient. A composition comprising antibody 1 for use simultaneously, separately or sequentially in combination with antibody 2, wherein antibody 1 comprises two heavy chains and two light chains. The chain comprises a heavy chain variable region (HCVR) having a specific amino acid sequence, the light chain comprises a light chain variable region (LCVR) having a specific amino acid sequence, antibody 2 comprises two heavy chains and two A light chain, the heavy chain comprises an HCVR having a specific amino acid sequence, the light chain comprises an LCVR having a specific amino acid sequence, Antibody 1 is administered at a dose of 400 mg to 800 mg, and Antibody 2 is 200 mg. A composition for treating non-small cell lung cancer, which is administered in a dose.
