( 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. Mental status changes occurred in 1.3% of patients; 1.1% of these events were severe. Seizures occurred in 1.9% of patients, sometimes in conjunction with other neurologic findings. Sleep effects occurred in 12% of patients. The median time to first onset of any CNS effect was 1.4 months (1 day to 3.4 years). Overall, 2.1% of patients required permanent discontinuation of LORBRENA for a CNS effect; 10% required temporary discontinuation and 8% required dose reduction. Withhold and resume at the same dose or at a reduced dose or permanently discontinue LORBRENA based on severity [see Dosage and Administration (2.3) ] . 5.3 Hyperlipidemia Increases in serum cholesterol and triglycerides can occur in patients receiving LORBRENA [see Adverse Reactions (6.1) ] . Grade 3 or 4 elevations in total cholesterol occurred in 18% and Grade 3 or 4 elevations in triglycerides occurred in 19% of the 476 patients who received 100 mg LORBRENA once daily. The median time to onset was 15 days for both hypercholesterolemia and hypertriglyceridemia. Approximately 4% and 7% of patients required temporary discontinuation and 1% and 3% of patients required dose reduction of LORBRENA for elevations in cholesterol and in triglycerides in Study B7461001 and Study B7461006, respectively. Eighty-three percent of patients required initiation of lipid-lowering medications, with a median time to onset of start of such medications of 17 days. Initiate or increase the dose of lipid-lowering agents in patients with hyperlipidemia. Monitor serum cholesterol and triglycerides before initiating LORBRENA, 1 and 2 months after initiating LORBRENA, and periodically thereafter. Withhold and resume at the same dose for the first occurrence; resume at the same or a reduced dose of LORBRENA for recurrence based on severity [see Dosage and Administration (2.3) ]. 5.4 Atrioventricular Block PR interval prolongation and atrioventricular (AV) block can occur in patients receiving LORBRENA [see Adverse Reactions (6.1) , Clinical Pharmacology (12.2) ]. In 476 patients who received 100 mg LORBRENA once daily and who had a baseline electrocardiography (ECG), 1.9% experienced AV block and 0.2% experienced Grade 3 AV block and underwent pacemaker placement. Monitor ECG prior to initiating LORBRENA and periodically thereafter. Withhold and resume at a reduced dose or at the same dose in patients who undergo pacemaker placement.

The pooled safety population described in the Warnings and Precautions section reflects exposure to LORBRENA in 476 patients who received 100 mg LORBRENA once daily in Study B7461001 (N=327) and Study B7461006 (N=149). Among 476 patients who received LORBRENA, 75% were exposed for 6 months or longer and 61% were exposed for greater than 1 year. In this pooled safety population, the most frequent adverse reactions in ≥ 20% of 476 patients who received LORBRENA were edema (56%), peripheral neuropathy (44%), weight gain (31%), cognitive effects (28%), fatigue (27%), dyspnea (27%), arthralgia (24%), diarrhea (23%), mood effects (21%), and cough (21%). The most frequent Grade 3–4 laboratory abnormalities in ≥ 20% of 476 patients who received LORBRENA were hypercholesterolemia (21%) and hypertriglyceridemia (21%). Previously Untreated ALK-Positive Metastatic NSCLC (CROWN Study) The safety of LORBRENA was evaluated in 149 patients with ALK-positive NSCLC in a randomized, open-label, active-controlled trial for the treatment of patients with ALK-positive, locally advanced or metastatic, NSCLC who had not received previous systemic treatment for advanced disease [see Clinical Studies (14) ]. 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. The most frequent adverse reactions that led to dose reductions were edema (5%), hypertriglyceridemia (4.0%), and peripheral neuropathy (3.4%). Tables 2 and 3 summarize most frequent adverse reactions and laboratory abnormalities, respectively, in patients treated with LORBRENA in Study B7461006.

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.

Use in specific populations

Lactation : Advise not to breastfeed. ( 8.2 ) 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. 8.2 Lactation Risk Summary There are no data on the presence of lorlatinib or its metabolites in either human or animal milk or its effects on the breastfed infant or on milk production. Because of the potential for serious adverse reactions in breastfed infants, instruct women not to breastfeed during treatment with LORBRENA and for 7 days after the final dose. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating LORBRENA [see Use in Specific Populations (8.1) ] . Contraception LORBRENA can cause embryo-fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Females Advise female patients of reproductive potential to use effective non-hormonal contraception during treatment with LORBRENA and for at least 6 months after the final dose. Advise females of reproductive potential to use a non-hormonal method of contraception, because LORBRENA can render hormonal contraceptives ineffective [see Drug Interactions (7.2) ] . Males Based on genotoxicity findings, advise males with female partners of reproductive potential to use effective contraception during treatment with LORBRENA and for at least 3 months after the final dose [see Nonclinical Toxicology (13.1) ] . Infertility Males Based on findings from animal studies, LORBRENA may transiently impair male fertility [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use The safety and effectiveness of LORBRENA in pediatric patients have not been established. 8.5 Geriatric Use Of the patients in Study B7461001 (N=295) and Study B7461006 (N=149) who received 100 mg LORBRENA orally once daily, 18% and 40% of patients, respectively, were aged 65 years or older. No clinically important differences in safety or efficacy were observed between patients aged 65 years or older and younger patients. 8.6 Hepatic Impairment In patients with severe hepatic impairment (Child-Pugh C), the recommended dosage of LORBRENA is 50 mg orally once daily [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3) ] . No dose adjustment is recommended for patients with mild (total bilirubin ≤ ULN with AST > ULN or total bilirubin >1 to 1.5 × ULN with any AST) to moderate (Child-Pugh B) hepatic impairment [see Clinical Pharmacology (12.3) ] . 8.7 Renal Impairment In patients with CL cr 15 to <30 mL/min (estimated by Cockcroft‑Gault), the recommended dosage of LORBRENA is 75 mg orally once daily [see Dosage and Administration (2.6) and Clinical Pharmacology (12.3) ] . No dose adjustment is recommended for patients with CLcr 30 to 89 mL/min (estimated by Cockcroft‑Gault) [see Clinical Pharmacology (12.3) ] .

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.

Mechanism of action

12.1 Mechanism of Action Lorlatinib is a kinase inhibitor with in vitro activity against ALK and ROS1 as well as TYK1, FER, FPS, TRKA, TRKB, TRKC, FAK, FAK2, and ACK. Lorlatinib demonstrated in vitro activity against multiple mutant forms of the ALK enzyme, including some mutations detected in tumors at the time of disease progression on crizotinib and other ALK inhibitors. In mice subcutaneously implanted with tumors harboring EML4 fusions with either ALK variant 1 or ALK mutations, including the G1202R and I1171T mutations detected in tumors at the time of disease progression on ALK inhibitors, administration of lorlatinib resulted in antitumor activity. Lorlatinib also demonstrated anti-tumor activity and prolonged survival in mice implanted intracranially with EML4-ALK-driven tumor cell lines. The overall antitumor activity of lorlatinib in in vivo models was dose-dependent and correlated with inhibition of ALK phosphorylation.
