Arterial occlusions have occurred in at least 35% of ponatinib-treated patients. Some patients experienced more than 1 type of event. Events observed included fatal myocardial infarction (MI), stroke, stenosis of large arterial vessels of the brain, severe peripheral vascular disease, and the need for urgent revascularization procedures. Patients with and without cardiovascular risk factors, including patients 50 years and younger, experienced these events. Monitor for evidence of arterial occlusion. Interrupt or stop ponatinib immediately for arterial occlusion. A benefit-risk consideration should guide a decision to restart ponatinib therapy.
Heart failure, including fatalities, occurred in 9% of ponatinib-treated patients. Monitor cardiac function. Interrupt or stop ponatinib for new or worsening heart failure.
Hepatotoxicity, liver failure, and death have occurred in ponatinib-treated patients. Monitor hepatic function. Interrupt ponatinib if hepatotoxicity is suspected.
Venous occlusive events have occurred in 6% of ponatinib-treated patients. Monitor for evidence of venous thromboembolism. Consider dose modification or discontinuation of ponatinib in patients who develop serious venous thromboembolism.

Mechanism of Action
Ponatinib is a pan-BCR-ABL tyrosine kinase inhibitor with in vitro activity against cells expressing native or mutant BCR-ABL (including T315I); it also inhibits VEGFR, FGFR, PDGFR, EPH, and SRC kinases, as well as KIT, RET, TIE2, and FLT3.
Plasma concentrations not affected by food
Vd: 1223 L
Primarily hepatic through CYP3A4; CYP2C8, CYP2D6, and CYP3A5 are also involved in metabolism. Phase II metabolism occurs via esterases and/or amidases.

Concerns related to adverse effects:
- Arrhythmias: Cardiac arrhythmias (bradyarrhythmias and tachyarrhythmias) have been reported. The most commonly reported arrhythmia was atrial fibrillation; ~50% of events were grade 3 or 4. Other grade 3 or 4 rhythm disorders have occurred (case reports). Some events required hospitalization; symptomatic bradyarrhythmia which required pacemaker implantation occurred in a few cases. Monitor for sign/symptoms of bradycardia (fainting, dizziness, chest pain) and tachycardia (palpitations, dizziness). May require therapy interruption and further evaluation.
- Arterial occlusion: [US Boxed Warning]: Arterial occlusions have occurred in at least 35% of ponatinib-treated patients. Some patients experienced more than 1 type of event. Events included fatal myocardial infarction (MI), stroke, stenosis of large arterial vessels of the brain, severe peripheral vascular disease, and the need for urgent revascularization procedures; incidents were observed in patients with and without cardiovascular risk factors (including patients ≤50 years of age). Monitor closely for arterial occlusion; interrupt or discontinue therapy immediately for arterial occlusion. Consider risk:benefit ratio when deciding to restart therapy. Fatal and life-threatening arterial occlusion may occur within 2 weeks of therapy initiation and is not dose dependent (events have occurred at doses as low as 15 mg daily), and may cause recurrent or multisite occlusion. The most common risk factors for developing arterial occlusive events were hypertension, hyperlipidemia, and history of cardiac disease. Increasing age and a prior history of ischemia, hypertension, diabetes, or hyperlipidemia are also risk factors for development of ponatinib-associated vascular occlusion. Patients have required a revascularization procedure (cerebrovascular, coronary, and peripheral arterial) due to serious arterial thrombosis/occlusion. MI and coronary artery occlusion may result in heart failure due to myocardial ischemia. Cerebrovascular occlusion (including fatal stroke) has occurred; may cause stenosis over multiple segments in major arterial vessels that supply the brain. Peripheral arterial occlusive events, including fatal mesenteric artery occlusion and life-threatening peripheral arterial disease, have occurred. Some patients have required amputation due to digital or distal extremity necrosis. Renal artery stenosis (associated with worsening or refractory hypertension) has been reported.
- Bone marrow suppression: Severe myelosuppression (grade 3 or 4) is commonly observed with ponatinib, and the incidence was greater in patients with accelerated or blast phase CML and Ph+ ALL. The median onset to severe myelosuppression was 1 month (range: up to 40 months). Monitor blood counts closely; may require therapy interruption and/or dosage reduction.
- Fluid retention/edema: Serious fluid retention events, including fatality due to brain edema (case report), were observed in ponatinib-treated patients. Peripheral edema, pleural effusions, pericardial effusions, and peripheral swelling were commonly seen. Monitor patients for fluid retention; may require therapy interruption, dosage reduction, or discontinuation.
- GI perforation: Serious GI perforation (fistula) occurred very rarely; monitor for signs/symptoms of perforation and/or fistula. Permanently discontinue if GI perforation occurs.
- Heart failure:[US Boxed Warning]: Serious heart failure (HF) or left ventricular dysfunction, including fatalities, were reported in clinical trials. Monitor for signs/symptoms of HF; interrupt or discontinue ponatinib therapy for new or worsening HF.The most commonly reported heart failure events were congestive heart failure and decreased ejection fraction. Treat as clinically warranted if HF develops. Consider ponatinib discontinuation in the event of serious HF.
- Hemorrhage: Hemorrhagic events occurred in ponatinib-treated patients, including serious events such as cerebral (subdural hematoma) and GI hemorrhages; fatalities were reported. Serious bleeding episodes occurred more frequently in patients with accelerated or blast phase CML, and Ph+ ALL; most patients had grade 4 thrombocytopenia. Monitor platelet levels closely and for signs/symptoms of bleeding, and interrupt therapy if necessary.
- Hepatotoxicity: [US Boxed Warning]: Liver failure and death resulting from ponatinib-induced hepatotoxicity were observed; monitor liver function prior to and at least monthly (or as clinically indicated) during treatment. The median time to onset was 3 months (range: less than 1 month to 47 months). Hepatotoxicity may require treatment interruption (followed by dose reduction) or discontinuation. One case of fulminant hepatic failure leading to death occurred within 1 week of therapy initiation; acute liver failure has also occurred. Treatment may commonly result in ALT and/or AST, bilirubin, and alkaline phosphatase elevations. ALT/AST elevations may be irreversible.
- Hypertension: Treatment-emergent blood pressure elevations (systolic or diastolic) developed in over two-thirds of ponatinib-treated patients; symptomatic hypertension or hypertensive crisis were reported in several patients, requiring urgent intervention. Blood pressure may worsen in patients with preexisting hypertension. Monitor blood pressure closely, and manage elevated pressures as clinically indicated. May require therapy interruption, dosage reduction, or discontinuation if hypertension is resistant to medical management. Renal artery stenosis (associated with worsening, labile, or treatment-resistant hypertension) has occurred in some patients receiving ponatinib. Evaluate for renal artery stenosis for hypertension that significantly worsens, is labile, or treatment-resistant.
- Neuropathy: Peripheral and cranial neuropathy have been reported. Peripheral neuropathy, paresthesia, hypoesthesia, hyperesthesia, dysgeusia, and muscular weakness occurred most frequently; cranial neuropathy occurred rarely. In one-quarter of patients who experienced symptoms, neuropathy developed during the first month of therapy. Monitor for signs/symptoms of neuropathy; consider interrupting treatment if neuropathy develops.
- Ocular toxicity: Serious ocular events such as blindness and blurred vision have occurred with ponatinib use. Macular edema, retinal vein occlusion, and retinal hemorrhage have been reported in a small percentage of patients; conjunctival irritation, corneal erosion or abrasion, dry eye, conjunctivitis, conjunctival hemorrhage, hyperaemia and edema, or eye pain occurred more frequently. Other toxicities include cataracts, periorbital edema, blepharitis, glaucoma, eyelid edema, ocular hyperaemia, iritis, iridocyclitis, and ulcerative keratitis. Perform comprehensive ophthalmic exams prior to therapy initiation and periodically during treatment.
- Pancreatitis: Treatment-related lipase elevations and clinical pancreatitis occurred in clinical studies, including grade 3 and 4 events. The median time to onset was 14 days (range: 3 days to ~48 months); the majority of cases resolved within 2 weeks of therapy interruption or dose reduction. Monitor serum lipase every 2 weeks for the first 2 months and monthly thereafter or as clinically indicated; more frequent monitoring may be considered in patients with a history of pancreatitis or alcohol abuse. Monitor for clinical signs of pancreatitis, such as abdominal symptoms; interrupt therapy if necessary. Do not reinitiate treatment until complete resolution of symptoms and lipase level is <1.5 times ULN.
- Reversible posterior leukoencephalopathy syndrome: Reversible posterior leukoencephalopathy syndrome (RPLS) has been reported in postmarketing surveillance. Signs/symptoms include seizure, headache, decreased awareness, altered mental status, vision loss, and other visual and/or neurological disturbances. Hypertension is common; RPLS is diagnosed through MRI of the brain. Discontinue ponatinib for RPLS diagnosis; resume only if RPLS resolves and the benefit of treatment outweighs the risk.
- Tumor lysis syndrome: Hyperuricemia and serious tumor lysis syndrome (rare) were reported. Patients should receive adequate hydration and be monitored for elevated uric acid levels and/or the development of tumor lysis syndrome. Manage elevated uric acid levels prior to initiating therapy.
- Venous thromboembolism: [US Boxed Warning]: Venous occlusive events have occurred in 6% of ponatinib-treated patients. Monitor for evidence of venous thromboembolism. Consider dose modification or discontinuation of ponatinib in patients who develop serious venous thromboembolism. Venous thromboembolism, including deep vein thrombosis, pulmonary embolism, superficial thrombophlebitis, and retinal vein thrombosis have been reported.
- Wound healing impairment: As ponatinib inhibits vascular endothelial growth factor activity, therapy may impair wound healing. Hold therapy for at least 1 week prior to elective surgery; resume therapy ≥2 weeks following major surgery and until adequate wound healing.
- Cardiovascular disease: Patients with or without cardiovascular risk factors, and those with a prior history of ischemia, hypertension, diabetes, or hyperlipidemia may be at increased risk for vascular occlusion when treated with ponatinib. Monitor for signs/symptoms of occlusion; interrupt therapy and consider discontinuation if thrombosis/occlusion occurs.
- Chronic phase CML (newly diagnosed): In a randomized study of first-line treatment of newly diagnosed chronic phase CML, a 2-fold increased risk of serious adverse reaction was demonstrated for ponatinib as compared to imatinib; the study was stopped due to safety concerns. Arterial and venous thrombosis and occlusion events occurred at least twice as frequently in the ponatinib arm of the study (compared to the imatinib arm); a higher incidence of hematologic toxicity, pancreatitis, hepatotoxicity, heart failure, hypertension, and dermatologic/subcutaneous tissue disorders was also observed in patients receiving ponatinib. Ponatinib is not indicated and not recommended for treatment of newly diagnosed chronic phase CML.
- Hepatic impairment: A single-dose (30 mg) pharmacokinetic study found that ponatinib exposure was not increased in patients with hepatic impairment (Child-Pugh class A, B, or C) as compared to patients with normal hepatic function. While generally well tolerated, patients with hepatic impairment did have an increased overall incidence of adverse reactions (eg, GI disorders, pancreatitis). Monitor closely when administering to patients with impaired hepatic function. The starting dose should be reduced in patients with hepatic impairment.
Concurrent drug therapy issues:
- Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
- Elderly: Patients ≥65 years of age may be more likely to experience vascular occlusion, weakness, decreased appetite, dyspnea, increased lipase, muscle spasms, peripheral edema, and thrombocytopenia; monitor closely. Cautious dose selection is recommended based on greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
CBC with differential and platelets every 2 weeks for the first 3 months, then monthly or as clinically needed; liver function tests at baseline and at least monthly thereafter or more frequently if clinically warranted; serum lipase every 2 weeks for the first 2 months and monthly thereafter (more frequently in patients with a history of pancreatitis or alcohol abuse); serum electrolytes and uric acid; monitor cardiac function and blood pressure. Monitor for signs/symptoms of arterial/venous occlusion or thromboembolism, hemorrhage, fluid retention, pancreatitis (clinical signs), gastrointestinal perforation/fistula, hepatotoxicity (jaundice, anorexia, bleeding, bruising), reversible posterior leukoencephalopathy syndrome; comprehensive ocular exam at baseline and periodically; signs/symptoms of neuropathy
Based on animal data and its mechanism of action, ponatinib is expected to cause fetal harm if used during pregnancy. Verify pregnancy status prior to initiating ponatinib treatment. Women of childbearing potential should use effective contraception during treatment and for 3 weeks after the last dose.
