CP-358,774

What CP-358,774 Means in Everyday Medical Language

CP-358,774 is a medicine more commonly known as erlotinib hydrochloride or by its brand name, Tarceva. It belongs to a group of drugs called tyrosine kinase inhibitors. These drugs work by blocking a protein called the epidermal growth factor receptor (EGFR), which some cancer cells use to grow and spread. By blocking EGFR, CP-358,774 may help slow down or stop the growth of certain cancers.

Why CP-358,774 Can Matter in Cancer Care

This drug is important because it offers a targeted treatment option for some people with non-small cell lung cancer (NSCLC) that has spread and has specific changes (mutations) in the EGFR gene. It is also used together with another chemotherapy drug, gemcitabine, to treat pancreatic cancer that cannot be removed by surgery or has spread. Targeted therapies like CP-358,774 can sometimes work when other treatments do not, and they may have different side effects compared to traditional chemotherapy.
