5 WARNINGS AND PRECAUTIONS Hypertension : Monitor blood pressure and manage hypertension as clinically indicated. Interrupt, dose reduce or stop ICLUSIG if hypertension is not medically controlled. ( 2.2 , 5.5 ) Pancreatitis : Monitor serum lipase. Interrupt, then resume at the same or reduced dose or discontinue ICLUSIG based on severity. Evaluate for pancreatitis when lipase elevation is accompanied by abdominal symptoms. ( 2.2 , 5.6 ) Neuropathy : Monitor for symptoms of peripheral and cranial neuropathy. Interrupt, then resume at the same or reduced dose or discontinue ICLUSIG based on recurrence/severity. ( 2.2 , 5.8 ) Ocular Toxicity : Conduct comprehensive eye exams at baseline and periodically during treatment. ( 5.9 ) Hemorrhage : Monitor for hemorrhage and manage patients as clinically indicated. Interrupt, then resume at the same or reduced dose or discontinue ICLUSIG based on recurrence/severity. ( 2.2 , 5.10 ) Fluid Retention : Monitor for fluid retention and manage patients as clinically indicated. Interrupt, then resume at the same or reduced dose or discontinue ICLUSIG based on recurrence/severity. ( 2.2 , 5.11 ) Cardiac Arrhythmias : Monitor for signs or symptoms of arrhythmias and manage patients as clinically indicated. Interrupt, then resume at the same or reduced dose or discontinue ICLUSIG based on recurrence/severity. ( 5.12 ) Myelosuppression : Obtain complete blood counts every 2 weeks for the first 3 months and then monthly or as clinically indicated. If ANC less than 1 × 10 9 /L or platelets less than 50 × 10 9 /L, interrupt ICLUSIG until ANC at least 1.5 × 10 9 /L and platelets at least 75 × 10 9 /L, then resume at same or reduced dose. ( 2.2 , 5.13 ) Tumor Lysis Syndrome : Ensure adequate hydration and correct elevated uric acid levels prior to initiating ICLUSIG. ( 5.14 ) Reversible Posterior Leukoencephalopathy Syndrome (RPLS) : Interrupt ICLUSIG until resolution. The safety of resumption of ICLUSIG in patients upon resolution of RPLS is unknown. ( 5.15 ) Impaired Wound Healing and Gastrointestinal Perforation : Withhold ICLUSIG for at least 1 week prior to elective surgery. Do not administer for at least 2 weeks following major surgery and until adequate wound healing. The safety of resumption of ICLUSIG after resolution of wound healing complications has not been established. ( 5.16 ) Embryo-Fetal Toxicity : Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception. ( 5.17 , 8.1 , 8.3 ) 5.1 Arterial Occlusive Events Arterial occlusive events (AOEs), including fatalities, occurred in patients who received ICLUSIG [see Adverse Reactions (6.1) ] . In PhALLCON, 6% of 163 patients experienced AOEs, of which 3.1%, 1.8%, and 1.2% experienced cardiovascular, cerebrovascular, and peripheral vascular AOEs, respectively. The median time to onset of the first AOE was 11.3 months (range: 8 days to 2.8 years). Grade 3 or 4 AOEs occurred in 3.7% of patients; the most frequent Grade 3 or 4 AOEs were myocardial infarction (1.2%), peripheral arterial occlusive disease (1.2%), angina pectoris and cerebrovascular accident (0.6% each). Fatal AOE of sudden death occurred in 1 patient (0.6%). AOEs were more frequent with increasing age [see Use in Specific Populations (8.5) ] . In PhALLCON, patients with uncontrolled hypertension, hypertriglyceridemia, or diabetes were excluded. Patients with clinically significant, uncontrolled, or active cardiovascular disease, including any history of myocardial infarction, peripheral vascular infarction, revascularization procedure, venous thromboembolism, clinically significant atrial/ventricular tachyarrhythmias, unstable angina, or congestive heart failure within the 6 months prior to the first dose of ICLUSIG, were also excluded. In OPTIC, of the 94 patients who received a starting dose of 45 mg (45 mg → 15 mg), 18% experienced AOEs, of which 11%, 4.3%, and 3.2% experienced cardiovascular, cerebrovascula…

7 DRUG INTERACTIONS Strong CYP3A Inhibitors : Avoid coadministration or reduce ICLUSIG dose if coadministration cannot be avoided. ( 2.3 , 7.1 ) Strong CYP3A Inducers : Avoid coadministration. ( 7.1 ) 7.1 Effects of Other Drugs on ICLUSIG Strong CYP3A Inhibitors Coadministration of ICLUSIG with a strong CYP3A inhibitor increases ponatinib plasma concentrations [see Clinical Pharmacology (12.3) ] , which may increase the risk of ICLUSIG adverse reactions. Avoid coadministration of ICLUSIG with strong CYP3A inhibitors. If coadministration of ICLUSIG with strong CYP3A inhibitors cannot be avoided, reduce the ICLUSIG dosage [see Dosage and Administration (2.3) ] . Strong CYP3A Inducers Coadministration of ICLUSIG with a strong CYP3A inducer decreases ponatinib plasma concentrations [see Clinical Pharmacology (12.3) ] . Avoid coadministration of ICLUSIG with strong CYP3A inducers unless the benefit outweighs the risk of decreased ponatinib exposure. Monitor patients for reduced efficacy. Selection of concomitant medication with no or minimal CYP3A induction potential is recommended.

8.1 Pregnancy Risk Summary Based on findings in animals and its mechanism of action [see Clinical Pharmacology (12.1) ] , ICLUSIG can cause fetal harm when administered to a pregnant woman. There are no available data on ICLUSIG use in pregnant women. In animal reproduction studies, oral administration of ponatinib to pregnant rats during organogenesis caused adverse developmental effects at doses lower than human exposures at the maximum recommended human dose of 45 mg/day (see Data ) . Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data Ponatinib was studied for effects on embryo-fetal development in pregnant rats given oral doses of 0.3 mg/kg/day, 1 mg/kg/day, and 3 mg/kg/day during organogenesis (25 rats per group). At the maternally toxic dose of 3 mg/kg/day (equivalent to the AUC in patients receiving the maximum recommended dose of 45 mg/day), ponatinib caused embryo-fetal toxicity as shown by increased resorptions, reduced body weight, external alterations, multiple soft tissue and skeletal alterations, and reduced ossification. Embryo-fetal toxicities also were observed at 1 mg/kg/day (approximately 24% the AUC in patients receiving the maximum recommended dose of 45 mg/day) and involved multiple fetal soft tissue and skeletal alterations, including reduced ossification.

The most common adverse reactions identified in the Highlights of the Prescribing Information are based on two safety populations. The first is from a pooled safety population of 543 patients with CML or resistant or intolerant Ph+ ALL (OPTIC and PACE studies) who received ICLUSIG as a single agent at a starting dose of 45 mg orally once daily. In this pooled safety population, the most common (>20%) adverse reactions were rash and related conditions, arthralgia, abdominal pain, fatigue, headache, constipation, hypertension, dry skin, hepatotoxicity, fluid retention and edema, pyrexia, pancreatitis/lipase elevation, nausea, hemorrhage, anemia, AOEs and cardiac arrhythmias. The most common Grade 3 or 4 laboratory abnormalities (>20%) were platelet count decreased, neutrophil cell count decreased, and white blood cell decreased. The second safety population is from 163 patients with newly diagnosed Ph+ ALL (PhALLCON study) who received ICLUSIG in combination with chemotherapy at a starting dose of 30 mg orally once daily. The most common adverse reactions (>20%) included hepatotoxicity, arthralgia, rash and related conditions, headache, pyrexia, abdominal pain, constipation, fatigue, nausea, oral mucositis, hypertension, pancreatitis/lipase elevation, neuropathy peripheral, hemorrhage, febrile neutropenia, fluid retention and edema, vomiting, paresthesia, and cardi…
