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.

2.2 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.

2.3 Dosage Modifications for Adverse Reactions

ALUNBRIG dosage reductions for adverse reactions are summarized in Table 1.

Once reduced for adverse reactions, do not subsequently increase the dosage of ALUNBRIG. Permanently discontinue ALUNBRIG if patients are unable to tolerate the 60 mg once daily dose.

Recommendations for dosage modifications of ALUNBRIG for the management of adverse reactions are provided in Table 2.

2.4 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.

2.5 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.

2.6 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)].

2.7 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)].

5.1 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)].

5.2 Hypertension

In ALTA 1L, hypertension was reported in 32% of patients receiving ALUNBRIG; Grade 3 hypertension occurred in 13% of patients.

In ALTA, hypertension was reported in 11% of patients in the 90 mg group who received ALUNBRIG and 21% of patients in the 90→180 mg group. Grade 3 hypertension occurred in 5.9% of patients overall.

Control blood pressure prior to treatment with ALUNBRIG. Monitor blood pressure after 2 weeks and at least monthly thereafter during treatment with ALUNBRIG. Withhold ALUNBRIG for Grade 3 hypertension despite optimal antihypertensive therapy. Upon resolution or improvement to Grade 1, resume ALUNBRIG at the same dose. Consider permanent discontinuation of treatment with ALUNBRIG for Grade 4 hypertension or recurrence of Grade 3 hypertension [see Dosage and Administration (2.3), Adverse Reactions (6.1)].

Use caution when administering ALUNBRIG in combination with antihypertensive agents that cause bradycardia [see Warnings and Precautions (5.3)].

Monitor heart rate and blood pressure during treatment with ALUNBRIG. Monitor patients more frequently if concomitant use of drug known to cause bradycardia cannot be avoided [see Warnings and Precautions (5.2)].

For symptomatic bradycardia, withhold ALUNBRIG and review concomitant medications for those known to cause bradycardia. If a concomitant medication known to cause bradycardia is identified and discontinued or dose adjusted, resume ALUNBRIG at the same dose following resolution of symptomatic bradycardia; otherwise, reduce the dose of ALUNBRIG following resolution of symptomatic bradycardia. Discontinue ALUNBRIG for life-threatening bradycardia if no contributing concomitant medication is identified [see Dosage and Administration (2.3)].

Monitor AST, ALT and total bilirubin during treatment with ALUNBRIG, especially during first 3 months. Withhold ALUNBRIG for Grade 3 or 4 hepatic enzyme elevation with bilirubin less than or equal to 2 × ULN. Upon resolution or recovery to Grade 1 or less (less than or equal to 3 × ULN) or to baseline, resume ALUNBRIG at a next lower dose as described in Table 2. Permanently discontinue ALUNBRIG for Grade 2 to 4 hepatic enzyme elevation with concurrent total bilirubin elevation greater than 2 times the ULN in the absence of cholestasis or hemolysis [see Dosage and Administration (2.3), Adverse Reactions (6.1)].

5.8 Hyperglycemia

In ALTA 1L, 56% of patients who received ALUNBRIG experienced new or worsening hyperglycemia. Grade 3 hyperglycemia, based on laboratory assessment of serum fasting glucose levels, occurred in 7.5% of patients.

In ALTA, 43% of patients who received ALUNBRIG experienced new or worsening hyperglycemia. Grade 3 hyperglycemia, based on laboratory assessment of serum fasting glucose levels, occurred in 3.7% of patients. Two of 20 (10%) patients with diabetes or glucose intolerance at baseline required initiation of insulin while receiving ALUNBRIG.

Assess fasting serum glucose prior to initiation of ALUNBRIG and monitor periodically thereafter. Initiate or optimize antihyperglycemic medications as needed. If adequate hyperglycemic control cannot be achieved with optimal medical management, withhold ALUNBRIG until adequate hyperglycemic control is achieved and consider reducing the dose of ALUNBRIG as described in Table 1 or permanently discontinuing ALUNBRIG [see Dosage and Administration (2.3), Adverse Reactions (6.1)].

In ALTA 1L, photosensitivity occurred in 3.7% of patients who received ALUNBRIG, with 0.7% Grade 3 to 4.

In ALTA, 0.9% of patients who received ALUNBRIG in the 90 mg group experienced photosensitivity and 0.9% of patients in the 90 mg→180 mg group. Grade 3 to 4 photosensitivity was not reported in patients in the 90 mg group or in the 90→180 mg group.

Advise patients to limit sun exposure while taking brigatinib, and for at least 5 days after discontinuation of treatment. Advise patients, when outdoors to wear a hat and protective clothing, and use a broad-spectrum Ultraviolet A (UVA)/ Ultraviolet B (UVB) sunscreen and lip balm (SPF ≥30) to help protect against sunburn. Based on the severity withhold ALUNBRIG, then resume at the same dose, or reduce the dose, or permanently discontinue as described in Table 2 [see Dosage and Administration (2.3), Adverse Reactions (6.1)].

5.10 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. Advise males with female partners of reproductive potential to use effective contraception during treatment and for at least 3 months after the last dose of ALUNBRIG [see Use in Specific Populations (8.1, 8.3), Clinical Pharmacology (12.1)].

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 to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

7.1 Effect of Other Drugs on ALUNBRIG

8.1 Pregnancy

8.2 Lactation

8.3 Females and Males of Reproductive Potential

8.4 Pediatric Use

The safety and effectiveness of ALUNBRIG in pediatric patients have not been established.

8.5 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.

8.6 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)].

8.7 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)].

12.1 Mechanism of Action

Brigatinib is a tyrosine kinase inhibitor (TKI) with in vitro activity at clinically achievable concentrations against multiple kinases including ALK, ROS1, insulin-like growth factor-1 receptor (IGF-1R), and FLT-3 as well as EGFR deletion and point mutations. Brigatinib inhibited autophosphorylation of ALK and ALK-mediated phosphorylation of the downstream signaling proteins STAT3, AKT, ERK1/2, and S6 in in vitro and in vivo assays. Brigatinib also inhibited the in vitro proliferation of cell lines expressing EML4-ALK and NPM-ALK fusion proteins and demonstrated dose-dependent inhibition of EML4-ALK-positive NSCLC xenograft growth in mice.

At clinically achievable concentrations (≤500 nM), brigatinib inhibited the in vitro viability of cells expressing EML4-ALK and 17 mutant forms associated with resistance to ALK inhibitors including crizotinib, as well as EGFR-Del (E746-A750), ROS1-L2026M, FLT3-F691L, and FLT3-D835Y. Brigatinib exhibited in vivo antitumor activity against 4 mutant forms of EML4-ALK, including G1202R and L1196M mutants identified in NSCLC tumors in patients who have progressed on crizotinib. Brigatinib also reduced tumor burden and prolonged survival in mice implanted intracranially with an ALK-driven tumor cell line.

12.2 Pharmacodynamics

Brigatinib exposure-response relationships and the time course of the pharmacodynamic response are unknown.

12.3 Pharmacokinetics

The geometric mean (CV%) steady-state maximum concentration (Cmax) of brigatinib at ALUNBRIG doses of 90 mg and 180 mg once daily was 552 (49%) ng/mL and 1452 (60%) ng/mL, respectively, and the corresponding area under the concentration-time curve (AUC0-Tau) was 8165 (45%) ng∙h/mL and 20276 (62%) ng∙h/mL. After a single dose and multiple dosing of ALUNBRIG, systemic exposure of brigatinib was dose proportional over the dose range of 60 mg (0.3 times the recommended dose of 180 mg) to 240 mg (1.3 times the recommended dose of 180 mg) once daily. The mean accumulation ratio after repeat dosing was 1.9 to 2.4.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity studies have not been performed with brigatinib.

Treatment with brigatinib resulted in chromosomal damage in an in vivo mammalian erythrocyte micronucleus in the rat, but was not mutagenic in the Ames or in vitro mammalian chromosome aberration tests.

Dedicated animal fertility studies were not conducted with brigatinib. Testicular toxicity was observed in repeat-dose animal studies at doses resulting in exposure as low as 0.2 times the exposure in patients at the 180 mg dose. In rats, findings included lower weight of testes, seminal vesicles and prostate gland, and testicular tubular degeneration; these effects were not reversible during the 2 month recovery period. In monkeys, findings included reduced size of testes along with microscopic evidence of hypospermatogenesis; these effects were reversible during the recovery period.

TKI-naïve Advanced ALK-positive NSCLC (ALTA 1L Study)

The efficacy of ALUNBRIG was demonstrated in a randomized (1:1), open-label, multicenter trial (ALTA 1L, NCT02737501) in adult patients with advanced ALK-positive NSCLC who had not previously received an ALK-targeted therapy. The study required patients to have an ALK rearrangement based on a local standard of care testing. Eligible patients were allowed to have up to 1 prior regimen of chemotherapy in the locally advanced or metastatic setting and were required to have an ECOG Performance Status of 0-2. Neurologically stable patients with treated or untreated central nervous system (CNS) metastases, including leptomeningeal metastases, were eligible. Patients with a history of interstitial lung disease, drug-related pneumonitis, or radiation pneumonitis were excluded. The major efficacy outcome measure was progression-free survival (PFS) as evaluated by a Blinded Independent Review Committee (BIRC) according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1). Additional efficacy outcome measures included confirmed overall response rate (ORR), duration of response (DOR), intracranial ORR, and intracranial DOR as evaluated by BIRC, and overall survival (OS).

A total of 275 patients were randomized to receive ALUNBRIG 180 mg orally once daily with a 7-day lead-in at 90 mg once daily (n = 137) or crizotinib 250 mg orally twice daily (n = 138). Of the 275 enrolled patients, 239 had positive results using the companion diagnostic test, the Vysis ALK Break Apart FISH Probe Kit; central results were negative for 20 patients and unavailable for 16 patients. Crossover from the crizotinib arm to the ALUNBRIG arm was permitted following disease progression.

Randomization was stratified by CNS metastases (present vs absent) and prior chemotherapy use for locally advanced or metastatic disease (yes, no).

Baseline demographic characteristics of the overall study population were: median age 59 years (range: 27 to 89, 32% 65 and over), 59% White and 39% Asian, 55% female, 39% ECOG PS 0 and 56% ECOG PS 1, and 58% never smokers. The disease characteristics of the overall study population were: 93% with Stage IV disease; 27% received chemotherapy in the locally advanced or metastatic setting; 14% had received CNS radiation; 31% had bone metastases; and 20% had liver metastases. CNS metastases were present in 35% (n = 96) of patients; 41 of those patients had measurable CNS lesions.

ALTA 1L demonstrated a statistically significant improvement in PFS by BIRC. Efficacy results from this study are described in Table 7 and Figure 1.

Figure 1: Kaplan-Meier Plot of Progression-Free Survival by BIRC in ALTA 1L

At the final analysis of overall survival, conducted approximately 3 years after the last patient enrolled, there were 92 deaths (33% of all patients) including 41 deaths on the ALUNBRIG arm and 51 deaths on the crizotinib arm; median OS was not reached on either arm.

BIRC assessment of confirmed intracranial ORR and intracranial DOR according to RECIST v1.1 in the subgroup of 41 patients with measurable CNS metastases (≥10 mm in longest diameter) at baseline are summarized in Table 8. Duration of intracranial response was measured from date of first intracranial response until intracranial disease progression (new lesions, intracranial target lesion diameter growth ≥20% from nadir, or unequivocal progression of intracranial nontarget lesions) or death.

ALK-positive Advanced or Metastatic NSCLC Previously Treated with Crizotinib

The efficacy of ALUNBRIG was demonstrated in a two-arm, open-label, multicenter trial (ALTA, NCT02094573) in adult patients with locally advanced or metastatic ALK-positive non-small cell lung cancer (NSCLC) who had progressed on crizotinib. The study required patients to have a documented ALK rearrangement based on an FDA-approved test or a different test with adequate archival tissue to confirm ALK arrangement by the Vysis® ALK Break-Apart fluorescence in situ hybridization (FISH) Probe Kit test. Key eligibility criteria included an ECOG Performance Status of 0-2 and progression on crizotinib. Neurologically stable patients with central nervous system (CNS) metastases were permitted to enroll. Patients with a history of interstitial lung disease or drug-related pneumonitis or who had received crizotinib within 3 days of the first dose of brigatinib were excluded. The major efficacy outcome measure was confirmed overall response rate (ORR) according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1) as evaluated by an Independent Review Committee (IRC). Additional efficacy outcome measures included Investigator-assessed ORR, duration of response (DOR), intracranial ORR, and intracranial DOR.

A total of 222 patients were randomized to receive ALUNBRIG either 90 mg once daily (90 mg arm; n = 112) or 180 mg once daily following a 7-day lead-in at 90 mg once daily (90→180 mg arm; n = 110). Randomization was stratified by CNS metastases (present vs absent) and best prior response to crizotinib (complete or partial response vs any other response/unevaluable).

Baseline demographic characteristics of the overall study population were: median age 54 years (range: 18 to 82, 23% 65 and over), 67% White and 31% Asian, 57% female, 36% ECOG PS 0 and 57% ECOG PS 1, and 95% never or former smokers. The disease characteristics of the overall study population were: Stage IV disease in 98%, adenocarcinoma histology in 97%, prior systemic chemotherapy in 74%, CNS metastases in 69% (61% had received prior CNS radiation), bone metastases in 39%, and liver metastases in 26% of patients. Sixty-four percent of patients had an objective response to prior crizotinib.

The median duration of follow-up was 8 months (range: 0.1 to 20.2). Efficacy results from ALTA are summarized in Table 9.

IRC assessment of intracranial ORR and intracranial DOR according to RECIST v1.1 in the subgroup of 44 patients with measurable CNS metastases (≥10 mm in longest diameter) at baseline are summarized in Table 10. Duration of intracranial response was measured from date of first intracranial response until intracranial disease progression (new lesions, intracranial target lesion diameter growth ≥20% from nadir, or unequivocal progression of intracranial nontarget lesions) or death.

Store at controlled room temperature 20°C to 25°C (68°F to 77°F); excursions permitted between 15°C to 30°C (59°F to 86°F) (see USP).
