( 5.8 , 7.2 , 8.1 , 8.3 ) 5.1 Risk of Serious Hepatotoxicity with Concomitant Use of Strong CYP3A Inducers Severe hepatotoxicity occurred in 10 of 12 healthy subjects receiving a single dose of LORBRENA with multiple daily doses of rifampin, a strong CYP3A inducer. Grade 4 alanine aminotransferase (ALT) or aspartate aminotransferase (AST) elevations occurred in 50% of subjects, Grade 3 ALT or AST elevations occurred in 33% and Grade 2 ALT or AST elevations occurred in 8%. ALT or AST elevations occurred within 3 days and returned to within normal limits after a median of 15 days (7 to 34 days); the median time to recovery was 18 days in subjects with Grade 3 or 4 ALT or AST elevations and 7 days in subjects with Grade 2 ALT or AST elevations [see Drug Interactions (7.1) ] . LORBRENA is contraindicated in patients taking strong CYP3A inducers. Discontinue strong CYP3A inducers for 3 plasma half-lives of the strong CYP3A inducer prior to initiating LORBRENA [see Contraindications (4) , Drug Interactions (7.1) ] . 5.2 Central Nervous System Effects A broad spectrum of central nervous system (CNS) effects can occur in patients receiving LORBRENA. These include seizures, psychotic effects and changes in cognitive function, mood (including suicidal ideation), speech, mental status, and sleep. Overall, CNS effects occurred in 52% of the 476 patients who received 100 mg LORBRENA once daily in clinical trials [see Adverse Reactions (6.1) ] . Cognitive effects occurred in 28% of the 476 patients; 2.9% of these events were severe (Grade 3 or 4). Mood effects occurred in 21% of patients; 1.7% of these events were severe. Speech effects occurred in 11% of patients; 0.6% of these events were severe. Psychotic effects occurred in 7% of patients; 0.6% of these events were severe.

Drug interactions

7 DRUG INTERACTIONS • Strong CYP3A Inducers : Contraindicated. ( 2.4 , 7.1 ) • Moderate CYP3A Inducers : Avoid concomitant use. If concomitant use cannot be avoided, increase the LORBRENA dose. ( 2.4 , 7.1 ) • Strong CYP3A Inhibitors : Avoid concomitant use; reduce LORBRENA dose if concomitant use cannot be avoided. ( 2.4 , 7.1 ) • Fluconazole : Avoid concomitant use; reduce LORBRENA dose if concomitant use cannot be avoided. ( 2.4 , 7.1 ) • Certain CYP3A Substrates : Avoid concomitant use with CYP3A substrates for which minimal concentration changes may lead to serious therapeutic failures. ( 7.2 ) • Certain P-gp Substrates : Avoid concomitant use with P-gp substrates for which minimal concentration changes may lead to serious therapeutic failures. ( 7.2 ) 7.1 Effect of Other Drugs on LORBRENA Strong CYP3A Inducers LORBRENA is contraindicated in patients taking strong CYP3A inducers [see Contraindication (4) ] . Discontinue strong CYP3A inducers for 3 plasma half-lives of the strong CYP3A inducer prior to initiating LORBRENA [see Dosage and Administration (2.3) ] . Concomitant use of LORBRENA with a strong CYP3A inducer decreased lorlatinib plasma concentrations [see Clinical Pharmacology (12.3) ] , which may decrease the efficacy of LORBRENA. Severe hepatotoxicity occurred in healthy subjects receiving LORBRENA with rifampin, a strong CYP3A inducer. In 12 healthy subjects receiving a single 100 mg dose of LORBRENA with multiple daily doses of rifampin, Grade 3 or 4 increases in ALT or AST occurred in 83% of subjects and Grade 2 increases in ALT or AST occurred in 8%. A possible mechanism for hepatotoxicity is through activation of the pregnane X receptor (PXR) by LORBRENA and rifampin, which are both PXR agonists. Moderate CYP3A Inducers Avoid concomitant use of moderate CYP3A inducers with LORBRENA. If concomitant use is unavoidable, increase the LORBRENA dose [see Dosage and Administration (2.4) ] . Concomitant use of LORBRENA with a moderate CYP3A inducer decreased lorlatinib plasma concentrations, which may decrease the efficacy of LORBRENA [see Clinical Pharmacology (12.3) ] . Strong CYP3A Inhibitors Avoid concomitant use of LORBRENA with a strong CYP3A inhibitor. If concomitant use cannot be avoided, reduce the LORBRENA dosage [see Dosage and Administration (2.4) ] . Concomitant use with a strong CYP3A inhibitor increased lorlatinib plasma concentrations [see Clinical Pharmacology (12.3) ] , which may increase the incidence and severity of adverse reactions of LORBRENA. Fluconazole Avoid concomitant use of LORBRENA with fluconazole. If concomitant use cannot be avoided, reduce the LORBRENA dosage [see Dosage and Administration (2.4) ] . Concomitant use of LORBRENA with fluconazole may increase lorlatinib plasma concentrations [see Clinical Pharmacology (12.3) ] , which may increase the incidence and severity of adverse reactions of LORBRENA. 7.2 Effect of LORBRENA on Other Drugs Certain CYP3A Substrates Avoid concomitant use of LORBRENA with certain CYP3A substrates, for which minimal concentration changes may lead to serious therapeutic failures. If concomitant use is unavoidable, increase the CYP3A substrate dosage in accordance with approved product labeling. LORBRENA is a moderate CYP3A inducer. Concomitant use of LORBRENA decreases the concentration of CYP3A substrates [see Clinical Pharmacology (12.3) ] , which may reduce the efficacy of these substrates. Certain P-glycoprotein (P-gp) Substrates Avoid concomitant use of LORBRENA with certain P-gp substrates for which minimal concentration changes may lead to serious therapeutic failures. If concomitant use is unavoidable, increase the P-gp substrate dosage in accordance with approved product labeling. LORBRENA is a moderate P-gp inducer. Concomitant use of LORBRENA decreases the concentration of P-gp substrates [see Clinical Pharmacology (12.3) ] , which may reduce the efficacy of these substrates.

Pregnancy

8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1) ] , LORBRENA can cause embryo-fetal harm when administered to a pregnant woman. There are no available data on LORBRENA use in pregnant women. Administration of lorlatinib to pregnant rats and rabbits by oral gavage during the period of organogenesis resulted in malformations, increased post-implantation loss, and abortion at maternal exposures that were equal to or less than the human exposure at the recommended dose of 100 mg once daily based on AUC (see Data ) . Advise a pregnant woman 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 are 2 to 4% and 15 to 20%, respectively. Data Animal Data Preliminary embryo-fetal development studies investigating the administration of lorlatinib during the period of organogenesis were conducted in rats and rabbits. In rabbits, lorlatinib administration resulted in abortion and total loss of pregnancy at doses of 15 mg/kg (approximately 3 times the human exposure at the recommended dose of 100 mg) or greater. At a dose of 4 mg/kg (approximately 0.6 times the human exposure at the recommended dose of 100 mg) toxicities included increased post-implantation loss and malformations including rotated limbs, malformed kidneys, domed head, high arched palate, and dilation of the cerebral ventricles. In rats, administration of lorlatinib resulted in total loss of pregnancy at doses of 4 mg/kg (approximately 5 times the human exposure at the recommended dose of 100 mg) or greater. At a dose of 1 mg/kg (approximately equal to the human exposure at the recommended dose of 100 mg) there was increased post-implantation loss, decreased fetal body weight, and malformations including gastroschisis, rotated limbs, supernumerary digits, and vessel abnormalities.

The median duration of exposure to LORBRENA was 16.7 months (4 days to 34.3 months) and 76% received LORBRENA for at least 12 months. Serious adverse reactions occurred in 34% of patients treated with LORBRENA; the most frequently reported serious adverse reactions were pneumonia (4.7%), dyspnea (2.7%), respiratory failure (2.7%), cognitive effects (2.0%), and pyrexia (2.0%). Fatal adverse reactions occurred in 3.4% of patients treated with LORBRENA and included pneumonia (0.7%), respiratory failure (0.7%), cardiac failure acute (0.7%), pulmonary embolism (0.7%), and sudden death (0.7%). Permanent discontinuation of LORBRENA due to adverse reactions occurred in 6.7% of patients. The most frequent adverse reaction that led to permanent discontinuation of LORBRENA was cognitive effects (1.3%). Adverse reactions leading to dose interruptions occurred in 49% of patients treated with LORBRENA. The most frequent adverse reactions that led to dose interruptions of LORBRENA were hypertriglyceridemia (7%), edema (5%), pneumonia (4.7%) cognitive effects (4.0%), mood effects (4.0%), and hypercholesterolemia (3.4%). Adverse reactions leading to dose reductions occurred in 21% of patients treated with LORBRENA.
