Abstract

Purpose: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have had a significant impact on non–small-cell lung cancer (NSCLC) outcomes, particularly for patients with EGFR mutations. Resistance emerges after 9 to 12 months, primarily mediated by the T790M resistance mutation. We studied neratinib, an irreversible pan-ErbB TKI that may overcome T790M. Patients and Methods: Patients with advanced NSCLC underwent EGFR sequencing of available tumor tissue at enrollment. Those with ≥ 12 weeks of prior TKI therapy were placed in arm A if they were EGFR mutation positive or arm B if they were wild-type. Arm C included TKI-naïve patients with adenocarcinoma and light smoking histories (≤ 20 pack-years). All patients received daily oral neratinib, initially at 320 mg but subsequently reduced to 240 mg because of excessive diarrhea. The primary end point was objective response rate (RR). Results: One-hundred sixty-seven patients were treated: 91 in arm A, 48 in arm B, and 28 in arm C. Diarrhea was the most common toxicity; grade 3 incidence was 50% at 320 mg but improved to 25% after dose reduction. The RR was 3% in arm A and zero in arms B and C. No patients with known T790M responded. Notably, three of four patients with an exon 18 G719X EGFR mutation had a partial response and the fourth had stable disease lasting 40 weeks. Conclusion: Neratinib had low activity in patients with prior benefit from TKIs and in TKI-naïve patients, potentially because of insufficient bioavailability from diarrhea-imposed dose limitation. Responses were seen in patients with the rare G719X EGFR mutation, highlighting the importance of obtaining comprehensive genetic information on trials of targeted agents.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
