How Does It Work?

Ponatinib belongs to a group of medicines known as tyrosine kinase inhibitors. Tyrosine kinases are proteins found in the body that control cell function, including cell growth. Ponatinib works by blocking the signal of certain tyrosine kinases, including but not limited to:
  • A mutated kinase known as T315I mutant ABL
  • A kinase that is resistant to treatment with other tyrosine kinase inhibitors.
By inhibiting the activity of T315I mutant ABL and other kinases, ponatinib slows down or stops the production of the abnormal blood cells.
