Choose ALUNBRIG® (brigatinib): A Well-Established Safety Profile Post-Crizotinib

Safety and tolerability were studied in 219 patients with anaplastic lymphoma kinase (ALK)-positive metastatic non-small cell lung cancer (mNSCLC)1

The safety of ALUNBRIG was evaluated in 219 patients with locally advanced or metastatic ALK+ NSCLC who received at least 1 dose of ALUNBRIG in ALTA after experiencing disease progression on crizotinib.

  • Serious adverse reactions occurred in 38% of patients in the 90-mg arm and 40% of patients in the 90→180-mg arm. The most common serious adverse reactions were pneumonia (5.5% overall, 3.7% in the 90-mg arm, and 7.3% in the 90→180-mg arm) and interstitial lung disease (ILD)/pneumonitis (4.6% overall, 1.8% in the 90-mg arm, and 7.3% in the 90→180-mg arm)
    • Fatal adverse reactions occurred in 3.7% of patients, consisting of pneumonia (2 patients), sudden death, dyspnea, respiratory failure, pulmonary embolism, bacterial meningitis, and urosepsis (1 patient each)
  • Most common adverse reactions (≥25% of any grade) in the 90-mg arm were nausea (33%), fatigue (29%), headache (28%), and dyspnea (27%) and in the 90→180-mg arm were nausea (40%), diarrhea (38%), fatigue (36%), cough (34%), and headache (27%)
  • Median duration of treatment was 7.5 and 7.8 months in the 90-mg arm and 90→180-mg arm, respectively

Discontinuation Rates1

  • In ALTA, permanent discontinuation of ALUNBRIG due to adverse reactions occurred in 2.8% of patients in the 90-mg arm and 8.2% of patients in the 90→180-mg arm
  • The most frequent adverse reactions that led to discontinuation were ILD/pneumonitis (0.9% in the 90-mg arm and 1.8% in the 90→180-mg arm) and pneumonia (1.8% in the 90→180-mg arm only)

Dose Modifications1

  • 14% of patients required a dose reduction due to adverse reactions (7.3% in the 90-mg arm and 20% in the 90→180-mg arm)
  • The most common adverse reaction that led to dose reduction was increased creatine phosphokinase (CPK) for both regimens (1.8% in the 90-mg arm and 4.5% in the 90→180-mg arm)

ILD/Pneumonitis1

  • Severe, life-threatening, and fatal pulmonary adverse reactions consistent with interstitial lung disease (ILD)/pneumonitis have occurred with ALUNBRIG
  • In ALTA, ILD/pneumonitis occurred in 3.7% of patients in the 90-mg arm and 9.1% of patients in the 90→180-mg arm

Early in Treatment2

  • In ALTA, 6.4% (14 of 219 treated patients) experienced reactions consistent with possible ILD within 9 days of initiation of ALUNBRIG (median onset was 2 days). None occurred after escalation to 180 mg, and 7 of the 14 patients were successfully re-treated with ALUNBRIG2
  • 2.7% of patients had Grade 3-4 events within the first 9 days of treatment2
