Overview Indication | First-line HER2-positive gastric, GEJ, or esophageal adenocarcinoma; previously treated HER2-positive biliary tract cancer | HER2+ breast cancer, HER2+ gastric/GEJ adenocarcinoma | HER2-positive breast cancer (including regimen-specific first-line and early-stage indications); HER2-low/ultralow breast cancer, HER2-positive gastric cancer, HER2-mutant NSCLC and HER2-positive solid tumors: consult the current US label |

Positioning Key differentiator | Dual-epitope binding drives receptor clustering, faster internalization, and stronger signaling blockade than either monoclonal alone. In GEA the label splits IHC 3+ (chemo doublet) from IHC 3+ or 2+/ISH+ (chemo + Tevimbra). | novel bifunctional chelator (2E-C-NETA) for applications in 177 Lu-based TRT | High DAR (~8), bystander effect, HER2-low activity |
Positioning Known limitation | HER2 heterogeneity, PI3K pathway activation, and bypass RTK signaling. | resistance to trastuzumab-based targeted therapy and limited intratumoral antibody penetration continue to restrict clinical outcomes | HER2 antigen loss/downregulation, payload efflux, and dose-limiting ILD/pneumonitis leading to discontinuation. |
Positioning Development positioning | 1L GEA with fluoropyrimidine-platinum ± Tevimbra; 2L+ BTC monotherapy | — | Indication- and regimen-specific; includes 1L + pertuzumab in HER2-positive metastatic breast cancer |
Technology Payload | — | — | DXd (topo-I inhibitor) |
Technology Linker | — | — | Cleavable tetrapeptide |
MoA Mechanism | Simultaneous binding of two non-overlapping HER2 epitopes crosslinks adjacent receptors, causing receptor clustering, internalization, and degradation alongside ADCC and complement activity. | Trastuzumab binds domain IV of HER2, inhibiting ligand-independent HER2 signaling, mediating ADCC via Fcγ receptors, and inducing internalization/degradation of HER2. | Fam-trastuzumab deruxtecan is a HER2-directed antibody-drug conjugate: humanized anti-HER2 IgG1 linked via a cleavable tetrapeptide linker to DXd, a membrane-permeable topoisomerase I inhibitor. After binding HER2 on tumor cells, the conjugate is internalized; lysosomal proteases cleave the linker and release DXd, causing DNA damage and apoptosis. Released DXd can exert a bystander effect in neighboring cells. |
MoA Biomarker | GEA: PATHWAY 4B5 IHC and VENTANA Dual ISH. IHC 3+ for chemo doublet; IHC 3+ or IHC 2+/ISH+ when Tevimbra is added. BTC: HER2 IHC 3+. | HER2 IHC 3+ or ISH amplified (ASCO/CAP guidelines). | HER2 expression (IHC/ISH per indication); higher systemic exposure associated with greater ILD incidence (FDA label §12.2). |
Toxicology Species | — | Rat | Cynomolgus monkey, NHP, Rat, Hamster |
Toxicology Animal (cat.) | — | — | NHP |
Toxicology Major finding | Embryo-fetal toxicity warning. Diarrhea, infusion-related reactions, and left ventricular dysfunction require monitoring, as with the HER2 antibody class. | Cardiotoxicity (LVEF decline, CHF risk especially with anthracyclines); infusion reactions; myelosuppression in combos. | ILD-like lung findings at high exposure |
Toxicology CRS | N/A | N/A | Minimal |
Toxicology NOAEL | — | — | 10 mg/kg |
Clinical Safety signal | Embryo-fetal toxicity warning. Diarrhea, infusion-related reactions, and left ventricular dysfunction require monitoring, as with the HER2 antibody class. | Cardiotoxicity (LVEF decline, CHF risk especially with anthracyclines); infusion reactions; myelosuppression in combos. | ILD-like lung findings at high exposure |
