Pemazyre 4.5 mg tablets – patient leaflet, side effects, dosage

1. What Pemazyre is and what it is used for

Pemazyre contains the active substance pemigatinib, which belongs to a group of cancer medicines called tyrosine kinase inhibitors. It blocks the action of proteins in the cell called fibroblast growth factor receptor types 1, 2 and 3 (FGFR1, FGFR2, and FGFR3) that help regulate cell growth. Cancer cells may have an abnormal form of this protein. By blocking FGFR, pemigatinib can prevent the growth of such cancer cells.

Pemazyre is used:

• to treat adults with bile duct cancer (also

  known as cholangiocarcinoma) whose cancer cells have an abnormal form of the FGFR2 protein, and

• when the cancer has spread to other parts of

  the body or cannot be removed by surgery, and

• when treatment with other medicines is no

  longer working.

2. What you need to know before you take Pemazyre

  ingredients of this medicine (listed in section 6)
