  Grade 3 OR Grade 4	Withhold LORBRENA until symptoms resolve to less than or equal to Grade 2 or baseline. Resume LORBRENA at reduced dose.

  5.7 Hyperglycemia

  Hyperglycemia can occur in patients receiving LORBRENA

  [see Adverse Reactions (6.1)]

  . Hyperglycemia occurred in 9% of patients who received 100 mg LORBRENA, including Grade 3 or 4 in 3.2% of patients. The median time to onset of hyperglycemia was 4.8 months (1 day to 2.9 years), and 0.8% of patients temporarily discontinued LORBRENA for hyperglycemia.

  Assess fasting serum glucose prior to initiation of LORBRENA and monitor periodically thereafter. Withhold and resume at a reduced dose or permanently discontinue LORBRENA based on severity

• •Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus. Advise males and females of reproductive potential to use an effective non-hormonal method of contraception. (
  5.8 Embryo-Fetal Toxicity

  Based on findings from animal studies and its mechanism of action, LORBRENA can cause fetal harm when administered to a pregnant woman. 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 area under the curve (AUC).

  Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use an effective non-hormonal method of contraception, since LORBRENA can render hormonal contraceptives ineffective, during treatment with LORBRENA and for at least 6 months after the final dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with LORBRENA and for 3 months after the final dose

  7.2 Effect of LORBRENA on Other Drugs

  Certain CYP3A Substrates

  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. 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.

  Certain P-glycoprotein (P-gp) Substrates

  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. 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.

  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.

  8.3 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
