DescriptionNecitumumab is an intravenously administered recombinant monoclonal IgG1 antibody used in the treatment of non-small cell lung cancer (NSCLC) as an EGFR antagonist. It functions by binding to epidermal growth factor receptor (EGFR) and prevents binding of its ligands, a process that is involved in cell proliferation, metastasis, angiogenesis, and malignant progression. Binding of necitumumab to EGFR induces receptor internalization and degradation, thereby preventing further activation of EGFR which is beneficial in NSCLC as many patients have increased protein expression of EGFR. Necitumumab is approved for use in combination with cisplatin and gemcitabine as a first-line treatment for metastatic squamous non-small cell lung cancer (NSCLC).
Indication/DiseaseNecitumumab is approved for use in combination with cisplatin and gemcitabine as a first-line treatment for metastatic squamous non-small cell lung cancer (NSCLC). It is not indicated for treatment of non-squamous NSCLC.
PharmacodynamicsIn animal models administration of necitumumab to implanted mice resulted in increased antitumor activity in combination with gemcitabine and cisplatin as compared to mice receiving gemcitabine and cisplatin alone.
Mechanism of ActionNecitumumab is a recombinant human lgG1 monoclonal antibody that binds to the human epidermal growth factor receptor (EGFR) and blocks the binding of EGFR to its ligands. Expression and activation of EGFR has been correlated with malignant progression, induction of angiogenesis, and inhibition of apoptosis. Binding of necitumumab induces EGFR internalization and degradation in vitro. In vitro, binding of necitumumab also led to antibody-dependent cellular cytotoxicity (ADCC) in EGFR-expressing cells.
ToxicityThe poor safety profile of necitumumab has been one of the major limitations of its use. Rigorous monitoring of the following adverse events is recommended for the use of this drug: cardiopulmonary arrest, hypomagnesia, venous and arterial thromboembolic events, dermatologic toxicities, and infusion-related reactions. Due to observations of increased toxicity and mortality in treatment of non-squamous NSCLC, necitumumab is only recommended for the treatment of squamous NSCLC in combination with cisplatin and gemcitabine. Animal studies suggest potential embryo-fetal toxicity.
