Safety and Tolerability Studied in 219 Treated ALK+ NSCLC Patients In ALTA

The safety of ALUNBRIG was evaluated in 219 patients with locally advanced or metastatic ALK-positive non-small cell lung cancer 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 Rates

  • In ALTA, permanent discontinuation of ALUNBRIG® (brigatinib) 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 Modifications

  • 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)

  • 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 Treatment

  • 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 ALUNBRIG1
  • 2.7% of patients had Grade 3-4 events within the first 9 days of treatment

Recommendations for Management

  • Monitor for new or worsening respiratory symptoms (eg, dyspnea, cough, etc), particularly in the first week of initiating treatment with ALUNBRIG
  • Withhold ALUNBRIG in any patient with new or worsening respiratory symptoms, and promptly evaluate for ILD/pneumonitis or other causes of respiratory symptoms (eg, pulmonary embolism, tumor progression, and infectious pneumonia)
  • For Grade 1-2 adverse reactions, either resume ALUNBRIG with dose reduction as recommended 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
