경쟁 포지션: Challenges the ToGA trastuzumab-chemo backbone in 1L HER2+ GEA; still the only HER2 agent with a dedicated BTC indication.
기전. Simultaneous binding of two non-overlapping HER2 epitopes crosslinks adjacent receptors, causing receptor clustering, internalization, and degradation alongside ADCC and complement activity.

Biparatopic bispecific antibody (Azymetric)
One arm binds HER2 domain IV (trastuzumab epitope), the other domain II (pertuzumab epitope)
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).

Biparatopic bispecific antibody (Azymetric)
HER2 (biparatopic) · 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+.
Boxed warning for diarrhea and embryo-fetal toxicity; LVEF and infusion reactions
Challenges the ToGA trastuzumab-chemo backbone in 1L HER2+ GEA; still the only HER2 agent with a dedicated BTC indication.

GEA weight-banded (e.g. ≥70 kg: 2400 mg q3w or 1600 mg q2w); BTC historically 20 mg/kg q2w
HERIZON-GEA-01 OS 26.4 mo vs 19.2 mo with trastuzumab-chemo; BTC ORR ~52%
Boxed warning for diarrhea and embryo-fetal toxicity; LVEF and infusion reactions
Challenges the ToGA trastuzumab-chemo backbone in 1L HER2+ GEA; still the only HER2 agent with a dedicated BTC indication.
