Olaratumab (olaratumab) — Uses, Dosage, Side Effects & Safety

Drug class: Monoclonal Antibody; Antineoplastic Agent

Overview

Olaratumab is a prescription medicine used to treat certain types of soft tissue sarcoma, a rare cancer that develops in the body's connective tissues. It is typically given in combination with another chemotherapy drug called doxorubicin when surgery or radiation is not an option. Olaratumab works by targeting and blocking a protein called platelet-derived growth factor receptor alpha (PDGFR-α), which is involved in the growth of cancer cells. By blocking this protein, olaratumab helps slow or stop the growth of the tumor. Key points for patients: Olaratumab is given by intravenous (IV) infusion under medical supervision. It may cause side effects such as nausea, fatigue, and infusion reactions. Patients should report any unusual symptoms, especially signs of allergic reaction or infection, to their healthcare provider immediately.
