Tarceva (erlotinib)

Osi Pharms · FDA-approved active Verified Quality 80/100

Tarceva works by blocking the epidermal growth factor receptor, a protein that helps cancer cells grow.

Tarceva (erlotinib) is a small molecule kinase inhibitor originally developed by OSI PHARMS and currently owned by the same company. It targets the epidermal growth factor receptor (EGFR) to inhibit cancer cell growth. Tarceva is approved to treat adenocarcinoma of the pancreas and non-small cell lung cancer. The drug is off-patent, with 13 generic manufacturers available. Key safety considerations include rash, diarrhea, and liver damage.
