Necitumumab (brand name Portrazza) is a biologic medicine used to treat a type of lung cancer called squamous non-small cell lung cancer (NSCLC). It is a type of monoclonal antibody and works by targeting and blocking a protein called epidermal growth factor receptor (EGFR). This helps to slow or stop the growth of cancer cells. Necitumumab is usually used in combination with another chemotherapy drug, gemcitabine, and is given as an infusion into a vein (intravenously). It is only used to treat advanced or metastatic NSCLC after other treatments have failed.
Necitumumab, sold under the brand name Portrazza, is a medication used specifically for a certain type of lung cancer [1, 2, 3]. Here's a breakdown of its key features:
Type of Cancer:
- Necitumumab is designed to treat metastatic squamous non-small cell lung cancer (NSCLC) [1, 2, 3]. Squamous NSCLC is a specific subtype of lung cancer that originates from squamous cells lining the airways. Metastatic means the cancer has spread to other parts of the body.
How it Works:
- Necitumumab belongs to a class of drugs called monoclonal antibodies [1]. These are engineered proteins designed to target specific molecules.
- In the case of Necitumumab, it targets a protein called the epidermal growth factor receptor (EGFR) on the surface of cancer cells [1, 2, 3]. EGFR plays a role in cell growth and proliferation. By binding to EGFR, Necitumumab blocks its activity and hinders the growth and spread of cancer cells.
Administration:
- Necitumumab is given as an intravenous (IV) infusion, meaning it's injected into a vein [1, 3].
- The typical dosage is 800mg administered on days 1 and 8 of each 3-week treatment cycle, followed by gemcitabine and cisplatin, other chemotherapy drugs [3].
Important Considerations:
- Necitumumab is not effective for all types of lung cancer and is only approved for squamous NSCLC [1, 2].
- It can cause side effects, including fatigue, infection, decreased appetite, nausea, vomiting, diarrhea, headache, and allergic reactions [1, 3].
- Necitumumab is not suitable for everyone and should be used under the supervision of a doctor who specializes in cancer treatment [1].
Alternative Treatments for Lung Cancer:
There are various treatment options for lung cancer, depending on the stage and type. These can include surgery, radiation therapy, chemotherapy, and targeted therapies like Necitumumab.
