Alunbrig Prescribing Information
ALUNBRIG is indicated for the treatment of adult patients with anaplastic lymphoma kinase (ALK)-positive metastatic non-small cell lung cancer (NSCLC) as detected by an FDA-approved test [see Dosage and Administration (2.1)].
Patient Selection
Select patients for the treatment of metastatic NSCLC with ALUNBRIG based on the presence of ALK positivity in tumor specimens [see Clinical Studies (14)].
Information on FDA-approved tests for the detection of ALK rearrangements in NSCLC is available at http://www.fda.gov/CompanionDiagnostics.
Recommended Dosage
The recommended dosage for ALUNBRIG is:
- 90 mg orally once daily for the first 7 days; then increase the dose to 180 mg orally once daily.
Administer ALUNBRIG until disease progression or unacceptable toxicity.
If ALUNBRIG is interrupted for 14 days or longer for reasons other than adverse reactions, resume treatment at 90 mg once daily for 7 days before increasing to the previously tolerated dose.
ALUNBRIG may be taken with or without food. Instruct patients to swallow tablets whole. Do not crush or chew tablets.
If a dose of ALUNBRIG is missed or vomiting occurs after taking a dose, do not administer an additional dose and take the next dose of ALUNBRIG at the scheduled time.
Dosage Modifications for Adverse Reactions
ALUNBRIG dosage reductions for adverse reactions are summarized in Table 1.

Dosage Modifications for Strong or Moderate CYP3A Inhibitors
Avoid coadministration of strong or moderate CYP3A inhibitors during treatment with ALUNBRIG [see Drug Interactions (7.1), Clinical Pharmacology (12.3)]. If coadministration of a strong CYP3A inhibitor cannot be avoided, reduce the ALUNBRIG once daily dose by approximately 50% (i.e., from 180 mg to 90 mg, or from 90 mg to 60 mg). If coadministration of a moderate CYP3A inhibitor cannot be avoided, reduce the ALUNBRIG once daily dose by approximately 40% (i.e., from 180 mg to 120 mg, 120 mg to 90 mg, or from 90 mg to 60 mg). After discontinuation of a strong or moderate CYP3A inhibitor, resume the ALUNBRIG dose that was tolerated prior to initiating the CYP3A inhibitor.
Dosage Modifications for Moderate CYP3A Inducers
Avoid coadministration of moderate CYP3A inducers during treatment with ALUNBRIG [see Drug Interactions (7.1), Clinical Pharmacology (12.3)]. If coadministration of a moderate CYP3A inducer cannot be avoided, increase the ALUNBRIG once daily dose in 30 mg increments after 7 days of treatment with the current ALUNBRIG dose as tolerated, up to a maximum of twice the ALUNBRIG dose that was tolerated prior to initiating the moderate CYP3A inducer.
After discontinuation of a moderate CYP3A inducer, resume the ALUNBRIG dose that was tolerated prior to initiating the moderate CYP3A inducer.
Dosage Modifications for Patients with Severe Hepatic Impairment
Reduce the ALUNBRIG once daily dose by approximately 40% (i.e., from 180 mg to 120 mg, 120 mg to 90 mg, or from 90 mg to 60 mg) for patients with severe hepatic impairment (Child-Pugh C) [see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].
Dosage Modifications for Patients with Severe Renal Impairment
Reduce the ALUNBRIG once daily dose by approximately 50% (i.e., from 180 mg to 90 mg, or from 90 mg to 60 mg) for patients with severe renal impairment [creatinine clearance (CLcr) 15 to 29 mL/min by Cockcroft-Gault] [see Use in Specific Populations (8.7), Clinical Pharmacology (12.3)].

- 30 mg: round, white to off-white film-coated tablets with "U3" debossed on one side and plain on the other side
Pregnancy
Risk Summary
Based on its mechanism of action and findings in animals, ALUNBRIG can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no clinical data on the use of ALUNBRIG in pregnant women. Administration of brigatinib to pregnant rats during the period of organogenesis resulted in dose-related skeletal anomalies at doses as low as 12.5 mg/kg/day (approximately 0.7 times the human exposure by AUC at 180 mg once daily) as well as increased post-implantation loss, malformations, and decreased fetal body weight at doses of 25 mg/kg/day (approximately 1.26 times the human exposure at 180 mg once daily) or greater (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
In an embryo-fetal development study in which pregnant rats were administered daily doses of brigatinib during organogenesis, dose-related skeletal (incomplete ossification, small incisors) and visceral anomalies were observed at doses as low as 12.5 mg/kg/day (approximately 0.7 times the human exposure by AUC at 180 mg once daily). Malformations observed at 25 mg/kg/day (approximately 1.26 times the human AUC at 180 mg once daily) included anasarca (generalized subcutaneous edema), anophthalmia (absent eyes), forelimb hyperflexion, small, short and/or bent limbs, multiple fused ribs, bent scapulae, omphalocele (intestine protruding into umbilicus), and gastroschisis (intestines protruding through a defect in the abdominal wall) along with visceral findings of moderate bilateral dilatation of the lateral ventricles.
Lactation
Risk Summary
There are no data regarding the secretion of brigatinib in human milk or its effects on the breastfed infant or milk production. Because of the potential for adverse reactions in breastfed infants, advise lactating women not to breastfeed during treatment with ALUNBRIG and for 1 week following the final dose.
Females and Males of Reproductive Potential
Pregnancy Testing
Verify pregnancy status in females of reproductive potential prior to initiating ALUNBRIG [see Use in Specific Populations (8.1)].
Contraception
ALUNBRIG can cause fetal harm [see Use in Specific Populations (8.1)].
Females
Advise females of reproductive potential to use effective contraception during treatment with ALUNBRIG and for at least 4 months after the final dose.
Males
Because of the potential for genotoxicity, advise males with female partners of reproductive potential to use effective contraception during treatment with ALUNBRIG and for at least 3 months after the final dose [see Nonclinical Toxicology (13.1)].
Infertility
Based on findings in male reproductive organs in animals, ALUNBRIG may cause reduced fertility in males [see Nonclinical Toxicology (13.1)].
Pediatric Use
The safety and effectiveness of ALUNBRIG in pediatric patients have not been established.
Geriatric Use
Of the 359 patients enrolled in the ALTA 1L ALUNBRIG arm and in ALTA, 26.7% were 65 and older and 7.5% were 75 and older. No overall differences in safety or effectiveness were observed between patients ≥65 years and younger patients.
Hepatic Impairment
No dose adjustment is recommended for patients with mild hepatic impairment (Child-Pugh A) or moderate hepatic impairment (Child-Pugh B). Reduce the dose of ALUNBRIG for patients with severe hepatic impairment (Child-Pugh C) [see Dosage and Administration (2.6), Clinical Pharmacology (12.3)].
Renal Impairment
No dose adjustment is recommended for patients with mild or moderate renal impairment [creatinine clearance (CLcr) 30 to 89 mL/min by Cockcroft-Gault]. Reduce the dose of ALUNBRIG for patients with severe renal impairment (CLcr 15 to 29 mL/min) [see Dosage and Administration (2.7), Clinical Pharmacology (12.3)].
None.
Interstitial Lung Disease (ILD)/Pneumonitis
Severe, life-threatening, and fatal pulmonary adverse reactions consistent with interstitial lung disease (ILD)/pneumonitis have occurred with ALUNBRIG.
In Trial ALTA 1L, ILD/pneumonitis occurred in 5.1% of patients receiving ALUNBRIG. ILD/pneumonitis occurred within 8 days of initiation of ALUNBRIG in 2.9% of patients, with Grade 3 to 4 reactions occurring in 2.2% of patients.
In Trial ALTA, ILD/pneumonitis occurred in 3.7% of patients in the 90 mg group (90 mg once daily) and 9.1% of patients in the 90→180 mg group (180 mg once daily with 7-day lead-in at 90 mg once daily). Adverse reactions consistent with possible ILD/pneumonitis occurred within 9 days of initiation of ALUNBRIG (median onset was 2 days) in 6.4% of patients, with Grade 3 to 4 reactions occurring in 2.7%.
Monitor for new or worsening respiratory symptoms (e.g., dyspnea, cough, etc.), particularly during the first week of initiating ALUNBRIG. Withhold ALUNBRIG in any patient with new or worsening respiratory symptoms, and promptly evaluate for ILD/pneumonitis or other causes of respiratory symptoms (e.g., pulmonary embolism, tumor progression, and infectious pneumonia). For Grade 1 or 2 ILD/pneumonitis, either resume ALUNBRIG with dose reduction according to Table 1 after recovery to baseline or permanently discontinue ALUNBRIG. Permanently discontinue ALUNBRIG for Grade 3 or 4 ILD/pneumonitis or recurrence of Grade 1 or 2 ILD/pneumonitis [see Dosage and Administration (2.3), Adverse Reactions (6.1)].

Embryo-Fetal Toxicity
Based on its mechanism of action and findings in animals, ALUNBRIG can cause fetal harm when administered to pregnant women. There are no clinical data on the use of ALUNBRIG in pregnant women. Administration of brigatinib to pregnant rats during the period of organogenesis resulted in dose-related skeletal anomalies at doses as low as 12.5 mg/kg/day (approximately 0.7 times the human exposure by AUC at 180 mg once daily), as well as increased post-implantation loss, malformations, and decreased fetal body weight at doses of 25 mg/kg/day (approximately 1.26 times the human exposure at 180 mg once daily) or higher.
Advise women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with ALUNBRIG and for at least 4 months following the final dose.
