Necitumumab, sold under the brand name Portrazza, is a medication used for non-small-cell lung carcinoma (NSCLC).[1] Specifically it is used, together with gemcitabine and cisplatin, for squamous-cell cancer of the lung that has spread.[1] Such use; however, is not recommended in the United Kingdom.[3] It is given by gradual injection into a vein.[2]

Common side effects include rash and low magnesium.[2] Other side effects may include cardiac arrest and blood clots.[2] Use in pregnancy may harm the baby.[2] It is a monoclonal antibody that binds to epidermal growth factor receptor (EGFR).[3]

Necitumumab was approved for medical use in the United States in 2015.[1] While it was approved for use in Europe in 2016, this approval was subsequently withdrawn.[4] In the United Kingdom it cost the NHS £1,450 per dose as of 2021.[3] This amount in the United States costs about 4,500 USD.[5]

Medical uses

It was counterproductive in non-squamous non-small-cell lung carcinoma.[6][7]

Dosage

The typical dose is 800 mg on day 1 and 8 out of 21 days.[2]
