Description
Ponatinix (Ponatinib), generic is a prescription Tablets use to treat of blood cancer which is chronic phase, accelerated phase, or blast phase chronic myeloid leukemia (CML) or Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL) for whom no other tyrosine kinase inhibitor (TKI) medicines are received. Ponatinix manufactured by Beacon Pharma Ltd. in Bangladesh.
Indications
Ponatinib is a kinase inhibitor indicated for the:
- Adult patients with chronic phase, accelerated phase, or blast phase chronic myeloid leukemia (CML) or Ph+ ALL for whom no other tyrosine kinase inhibitor (TKI) therapy is indicated.

Ponatinib inhibited the in vitro tyrosine kinase activity of ABL and T315I mutant ABL with IC 50 concentrations of 0.4 nM and 2.0 nM, respectively. In vitro, activity of additional kinases with IC 50 concentrations between 0.1 nM and 20 nM, including members of the VEGFR, PDGFR, FGFR, EPH receptors and SRC families of kinases, and KIT, RET, TIE2, and FLT3. There is viability of cells expressing native or mutant BCR-ABL, including T315I. In mice, treatment with ponatinib reduce the size of tumors expressing native or T315I mutant BCR-ABL when compared to controls.
