What is Koselugo and how it works

Koselugo contains the active ingredient selumetinib.

Selumetinib is a type of medication called a MEK inhibitor. It acts by blocking certain proteins that are involved in the growth of cancer cells.

Koselugo is expected to reduce the size of tumors that grow along nerves, known as plexiform neurofibromas.

These tumors are caused by a genetic disease called neurofibromatosis type 1 (NF1).

What is Koselugo used for

Koselugo is used to treat children aged 3 years and older with plexiform neurofibromas that cannot be completely removed by surgery.

If you have any questions about how Koselugo works or why you have been prescribed this medication, consult your doctor.

Do not take Koselugo:

• if you are allergic to selumetinib or any of the other ingredients in this medicine (listed in section 6)
• if you have severe liver disease

Consult your doctor, pharmacist or nurse before starting to take Koselugo if you have any doubts.
