  • At initiation, 54% of patients had extrathoracic visceral metastases, including 34% with CNS metastases (including 11% with measurable CNS metastases) and 23% with liver metastases. Forty-two percent (42%) of patients had metastatic bone disease
  • A BICR assessment of CNS efficacy by RECIST v1.1 was conducted in the subgroup of 46/419 (11%) patients identified to have measurable CNS lesions on a baseline brain scan
  • This was an exploratory analysis and was not powered to show statistical significance

Clinically relevant adverse reactions in AURA3 in <10% of patients receiving TAGRISSO were epistaxis (5%), interstitial lung disease (3.9%), alopecia (3.6%), urticaria (2.9%), palmar-plantar erythrodysesthesia syndrome (1.8%), QTc interval prolongation (1.4%), keratitis (1.1%), erythema multiforme (0.7%), and skin hyperpigmentation (0.4%). QTc interval prolongation represents the incidence of patients who had a QTcF prolongation >500 msec.

Discontinuation rate and dose reductions due to ARs1

  • Dose reductions: 2.9% of patients treated with TAGRISSO
    • The most frequent adverse reactions leading to dose reductions or interruptions were prolongation of the QT interval as assessed by ECG (1.8%), neutropenia (1.1%), and diarrhea (1.1%)
  • Permanent discontinuations: 7% of patients treated with TAGRISSO
    • The most frequent adverse reaction leading to discontinuation of TAGRISSO was ILD/pneumonitis (3%)

Clinically relevant laboratory abnormalities in AURA3 that occurred in <20% of patients receiving TAGRISSO included increased blood creatinine (7%).

*NCI CTCAE v4.0.

Each test incidence, except for hyperglycemia, is based on the number of patients who had both baseline and at least one on-study laboratory measurement available (TAGRISSO 279, chemotherapy comparator 131).

Hyperglycemia is based on the number of patients who had both baseline and at least one on-study laboratory measurement available (TAGRISSO 270, chemotherapy 5; fasting glucose was not a protocol requirement for patients in the chemotherapy arm).

When patients progress on a first- or second-generation EGFR TKI, test for EGFR T790M resistance mutation

There are several FDA-approved, clinically validated diagnostic tests for the EGFR T790M mutation that use either tissue or plasma.1,3,4

Re-evaluate the feasibility of tissue testing with negative plasma results1,3,4

  • Select patients for the treatment of metastatic EGFR T790M mutation–positive NSCLC with TAGRISSO following progression on or after EGFR-TKI therapy based on the presence of an EGFR T790M mutation in tumor or plasma specimens
  • Testing for the presence of the T790M mutation in plasma specimens is recommended only in patients for whom a tumor biopsy cannot be obtained
  • If this mutation is not detected in a plasma specimen, re-evaluate the feasibility of biopsy for tumor tissue testing
