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 …

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 USE IN SPECIFIC POPULATIONS Lactation : Advise not to breastfeed. ( 8.2 ) 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. 8.2 Lactation Risk Summary There are no data on the presence of ponatinib in human milk, the effects on the breastfed child, or on milk production. Because of the potential for serious adverse reactions in the breastfed child, advise women not to breastfeed during treatment with ICLUSIG and for 1 week after the last dose. 8.3 Females and Males of Reproductive Potential ICLUSIG can cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1) ] . Pregnancy Testing Verify the pregnancy status of females of reproductive potential prior to initiating ICLUSIG. Contraception Females Advise females of reproductive potential to use effective contraception during treatment with ICLUSIG and for 3 weeks after the last dose. Infertility Females Based on animal data, ponatinib may impair fertility in females of reproductive potential [see Nonclinical Toxicology (13.1) ] . It is not known whether these effects on fertility are reversible. 8.4 Pediatric Use Safety and effectiveness of ICLUSIG have not been established in pediatric patients. Juvenile Animal Toxicity Data A juvenile toxicity study in 15 day old rats was conducted with daily oral gavage administration of ponatinib at 0.75 mg/kg/day, 1.5 mg/kg/day, or 3 mg/kg/day for 21 days. There were no adverse effects of ponatinib on juvenile rat developmental parameters (vaginal opening, preputial separation or bone measurements) observed in this study. Once daily oral administration of 3 mg/kg/day ponatinib to juvenile rats beginning on Day 15 postpartum (pp) resulted in mortality related to inflammatory effects after 6 to 7 days following initiation of treatment. The dose of 3 mg/kg/day is approximately 0.32 times the maximum recommended human dose of 45 mg/day on a mg/m 2 basis for a child. 8.5 Geriatric Use Of the 163 patients with Ph+ALL who received ICLUSIG in PhALLCON, 21% were 65 years and older and 7% were 75 years and older. Overall, no differences in efficacy of ICLUSIG were observed between patients 65 years of age or older compared to younger patients. AOEs occurred in 21% (7/34) of patients 65 years and older and 2.3% (3/129) of patients less than 65 years of age. Of the 94 patients with CP-CML who received ICLUSIG at a starting dose of 45 mg in OPTIC, 17% were 65 years and older and 2.1% were 75 years and older. Patients aged 65 years and older had a lower ≤1% BCR::ABL1 IS rate at 12 months (27%) th …

12.1 Mechanism of Action Ponatinib is a kinase inhibitor. 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. Ponatinib inhibited the 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. Ponatinib inhibited the in vitro viability of cells expressing native or mutant BCR::ABL, including T315I. In mice, treatment with ponatinib reduced the size of tumors expressing native or T315I mutant BCR::ABL when compared to controls.

11 DESCRIPTION Ponatinib is a kinase inhibitor. The chemical name for ponatinib hydrochloride is 3-(imidazo[1,2-b]pyridazin-3-ylethynyl)-4-methyl-N-{4-[(4-methylpiperazin-1-yl)methyl]-3-(trifluoromethyl)phenyl}benzamide hydrochloride. The molecular formula is C 29 H 28 ClF 3 N 6 O which corresponds to a formula weight of 569.02 g/mol. Its structure is shown below: Ponatinib HCl is an off-white to yellow powder with pKa of 2.77 and 7.8. The solubility of ponatinib in pH 1.7, 2.7, and 7.5 buffers is 7790 mcg/mL, 3.44 mcg/mL, and 0.16 mcg/mL, respectively, indicating a decrease in solubility with increasing pH. Each tablet for oral administration contains 10 mg, 15 mg, 30 mg or 45 mg of ponatinib equivalent to 10.68 mg, 16.03 mg, 32.05 mg, and 48.08 mg of ponatinib hydrochloride with the following inactive ingredients: lactose monohydrate, microcrystalline cellulose, sodium starch glycolate (type B), colloidal silicon dioxide, magnesium stearate and a tablet coating. The tablet coating consists of talc, polyethylene glycol, polyvinyl alcohol, and titanium dioxide. Chemical Structure

10 OVERDOSAGE Overdoses with ICLUSIG were reported in clinical trials. One patient was estimated to have been administered 540 mg via nasogastric tube. Two hours after the overdosage, the patient had an uncorrected QT interval of 520 ms. Subsequent ECGs showed normal sinus rhythm with uncorrected QT intervals of 480 ms and 400 ms. The patient died 9 days after the overdosage from pneumonia and sepsis. Another patient self-administered 165 mg on Cycle 1 Day 2. The patient experienced fatigue and non-cardiac chest pain on Day 3. Multiple doses of 90 mg per day for 12 days in a patient resulted in pneumonia, systemic inflammatory response, atrial fibrillation, and a moderate pericardial effusion. In the event of an overdosage, stop ICLUSIG, observe the patient and provide supportive treatment as appropriate.
