Tremelimumab-actl Injection

pronounced as (tre" me lim' ue mab)

Why is this medication prescribed?

Tremelimumab-actl injection is used in combination with durvalumab (Imfinzi) to treat hepatocellular carcinoma (HCC; a type of liver cancer) that cannot be treated with surgery. Tremelimumab-actl injection is also used in combination with durvalumab and platinum-containing chemotherapy to treat a certain type of non-small cell lung cancer (NSCLC) that has spread to other parts of the body. Tremelimumab-actl is in a class of medications called monoclonal antibodies. It works by helping your immune system to slow or stop the growth of cancer cells.

How should this medicine be used?

Tremelimumab-actl injection comes as a liquid to be injected into a vein over 60 minutes by a doctor or nurse in a hospital or medical facility. For the treatment of HCC, it is usually given as a single dose. For the treatment of NSCLC, it is usually given once every 3 weeks for 4 doses (cycles 1 to 4), and then as a single dose at week 16 (cycle 6).

Tremelimumab-actl injection may cause serious or life-threatening reactions during an infusion. A doctor or nurse will watch you closely while you are receiving the infusion to be sure you are not having a serious reaction to the medication. Tell your doctor or nurse immediately if you experience any of the following symptoms that may occur during the infusion: chills, flushing, shaking, dizziness, shortness of breath, wheezing, fever, itching, rash, back or neck pain, or feeling faint.

Your doctor may slow down your infusion, permanently or temporarily stop your tremelimumab-actl injection treatment, or treat you with additional medications depending on your response to the medication and any side effects that you experience. Talk to your doctor about how you are feeling during your treatment.
