}

4.5 mg, 9 mg, 13.5 mg tablets
pemigatinib

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 effect of protein in the cell called fibroblast growth factor receptor types 1, 2, and 3 (FGFR1, FGFR2, and FGFR3) which helps 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 called cholangiocarcinoma) whose cancer cells have an abnormal form of FGFR2‑ protein, and
  • when cancer has spread to other parts of the body or cannot be removed by surgery, and
  • when treatment with other drugs no longer works.
