Monoclonal antibodyFDA-approvedSecond-line
Vectibix
Generic name: panitumumab
How it works
Panitumumab binds to the epidermal growth factor receptor (EGFR) on cancer cells, blocking growth signals.
Cancer types
Colorectal Cancer— EGFR-expressing
Efficacy
In clinical trials, panitumumab improved response rates and survival in patients with metastatic colorectal cancer who have EGFR-expressing tumors.
Side effects
Moderate
Side effects can be significant and may require dose adjustments or supportive medication, but the treatment is usually continued.
