Product Name:
Ponatinib Hydrochloride
CAS Number:
1114544-31-8
Indication:
Ponatinib is indicated for the treatment of adult patients with chronic phase, accelerated phase, or blast phase chronic myeloid leukemia (CML) that is resistant or intolerant to prior tyrosine kinase inhibitor therapy or Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ALL) that is resistant or intolerant to prior tyrosine kinase inhibitor therapy.leuk
Mode of Action:

Ponatinib is a multi-target kinase inhibitor. Its primary cellular target is the Bcr-Abl tyrosine kinase protein which is constitutively active and promotes the progression of CML. This protein arises from the fused Bcr and Abl gene- what is commonly known as the Philadelphia chromosome. Ponatinib is unique in that it is especially useful in the treatment of resistant CML because it inhibits the tyrosine kinase activity of Abl and T315I mutant kinases. The T315I mutation confers resistance in cells as it prevents other Bcr-Abl inhibitors from binding to the Abl kinase. Other targets that ponatinib inhibits are members of the VEGFR, PDGFR, FGFR, EPH receptors and SRC families of kinases, and KIT, RET, TIE2, and FLT3. A decrease in tumour size expressing native or T315I mutant BCR-ABL have been observed in rats.

Metabolism:

At least 64% of a ponatinib dose undergoes phase I and phase II metabolism. CYP3A4 and to a lesser extent CYP2C8, CYP2D6 and CYP3A5 are involved in the phase I metabolism of ponatinib in vitro. Ponatinib is also metabolized by esterases and/or amidases.

Toxicity:

The most common non-hematologic adverse reactions (≥ 20%) were hypertension, rash, abdominal pain, fatigue, headache, dry skin, constipation, arthralgia, nausea, and pyrexia. Hematologic adverse reactions included thrombocytopenia, anemia, neutropenia, lymphopenia, and leukopenia.
