Proposed models illustrating the synergism of trastuzumab and pertuzumab. (A) A favored theory by assuming the distinctive action of trastuzumab and pertuzumab on HER2 homo- and heterodimers with or without ligand. (B) Hypothesis based on computational analysis, which suggests cooperative interactions between the two antibodies.
