What is olaratumab?
Olaratumab is a monoclonal antibody that blocks a certain type of cell receptor in the body that can affect tumor cell growth. Monoclonal antibodies are made to target and destroy only certain cells in the body, which may help slow or stop tumor growth.
Olaratumab is used in combination with another cancer medicine called doxorubicin, to treat adults with soft tissue sarcoma. Olaratumab is used when your condition cannot be treated with surgery or radiation.
Olaratumab was approved by the US Food and Drug Administration (FDA) on an "accelerated" basis. In clinical studies, olaratumab was shown to lengthen survival time. However, further studies are needed to determine if olaratumab is effective in larger numbers of patients with soft tissue sarcoma.
Olaratumab may also be used for purposes not listed in this medication guide.
Olaratumab can cause an infusion reaction during the injection. Tell your caregiver right away if you feel dizzy, light-headed, chilled, flushed, feverish, or short of breath.
You should not receive olaratumab if you are pregnant. Avoid pregnancy for at least 3 months after you stop using this medicine.
