1. What is LIBTAYO and what is it used for
LIBTAYO is a cancer medicine that contains the active substance cemiplimab, which is a monoclonal antibody.
LIBTAYO is used in adults to treat:
- a type of skin cancer called advanced cutaneous squamous cell carcinoma (CSCC).
 - a type of skin cancer called advanced basal cell carcinoma (BCC) for which you have received treatment with a Hedgehog pathway inhibitor and this treatment did not work well or was not well tolerated.
 - a type of lung cancer called non-small cell lung cancer (NSCLC).
 - a type of cancer called cervical cancer that has worsened during or after chemotherapy.
 
LIBTAYO may be given in combination with chemotherapy for NSCLC. It is important that you also read the package leaflets of the specific chemotherapy you may be receiving. If you have any questions about these medicines, ask your doctor.
LIBTAYO works by helping your immune system fight cancer.
2. What you need to know before you are given LIBTAYO
You should not be given LIBTAYO if:
- you are allergic to cemiplimab or any of the other ingredients of this medicine (listed in section 6).
 
If you think you may be allergic or are unsure, talk to your doctor before receiving LIBTAYO.
Warnings and precautions
Talk to your doctor or nurse before you are given LIBTAYO if:
- you have an autoimmune disease (a condition where the body attacks its own cells)

If any of the above applies to you, or if you are unsure, talk to your doctor or nurse before receiving LIBTAYO.
Pay attention to side effects
LIBTAYO may cause some serious side effects that you need to tell your doctor about immediately. These problems can occur at any time during treatment or even after your treatment has finished. You may have more than one side effect at the same time.
These serious side effects include:
- skin problems
 - lung problems (pneumonitis)
 - intestinal problems (colitis)
 - liver problems (hepatitis)
 - problems with hormone glands - especially the thyroid, pituitary, adrenal, and pancreas
 
- type 1 diabetes, including diabetic ketoacidosis (acid in the blood produced by diabetes)
 
- kidney problems (nephritis and renal failure)
 - problems with the central nervous system (such as meningitis)
 - infusion-related reactions
 - muscle problems (inflammation of the muscles called myositis)
 - inflammation of the heart muscle (myocarditis)
 - a disease in which the immune system produces too many normal cells that fight infection, called histiocytes and lymphocytes, which can cause various symptoms (hemophagocytic lymphohistiocytosis) (see the list of signs and symptoms in "Possible side effects")
 - problems in other parts of the body (see "Possible side effects")
 
Pay attention to these side effects while you are receiving LIBTAYO. See section 4 "Possible side effects". If you get any of these, tell your doctor immediately.
