( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Takeda Pharmaceuticals at 1-844-817-6468 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. 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...

Drug Interactions

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.

Pregnancy and Breastfeeding

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.

Overdosage

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.
