MARGENZA
MARGENZA is a HER2/neu receptor antagonist indicated for use in combination with chemotherapy to treat adult patients with metastatic HER2-positive breast cancer. It is intended for patients who have already received two or more prior anti-HER2 regimens. At least one of these previous treatments must have been administered for metastatic disease.
How MARGENZA Works
Margetuximab-cmkb binds to the extracellular domain of the HER2 protein, which inhibits tumor cell proliferation and reduces the shedding of the HER2 extracellular domain. The drug features a modified Fc region that increases binding to activating Fc receptors and decreases binding to inhibitory Fc receptors. These changes lead to enhanced antibody-dependent cellular cytotoxicity (ADCC) and natural killer (NK) cell activation against the tumor.

MARGENZA Target & Pathway
ProTarget
A receptor tyrosine kinase that promotes cell growth and division. Approximately 20% of breast cancers overexpress HER2, leading to aggressive tumor growth. Targeting HER2 blocks these growth signals and can trigger immune-mediated destruction of cancer cells.
Pathway Context
HER2 forms dimers with other HER family members to activate growth signaling
A receptor that triggers cell growth, proliferation, and survival when activated. Mutations or overexpression of EGFR drive many cancers, particularly lung cancer. Blocking EGFR stops the growth signals that fuel tumor progression.
