Public criteria

Who may be able to participate

The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.

Requirements people may need to meetInclusion criteria
  • Written informed consent
  • Advanced biopsy-proven metastatic non-small cell lung cancer
  • Somatic activating mutation in EGFR in a tumor biopsy or plasma cfDNA liquid biopsy
  • Prior treatment with osimertinib with response followed by disease progression
  • No prior first or second generation EGFR inhibitor treatment (gefitinib, afatinib, erlotinib)
  • Archival tissue available from a tumor biopsy done after disease progression on osimertinib or willing to undergo a tumor biopsy or liquid biopsy after disease progression on osimertinib prior to study initiation
  • Measurable (RECIST 1.1) indicator lesion not previously irradiated
  • Karnofsky performance status (KPS) \>/= 70%
  • Age \>/= 18 years old
  • Ability to swallow oral medication
  • Adequate organ function
  • AST, ALT \</= 3 x ULN
  • Total bilirubin \</= 1.5x ULN
  • Creatinine \</= 1.5x ULN OR calculated creatinine clearance \>/= 60ml/min
  • Absolute neutrophil count (ANC) \>/= 1000 cells/mm3
  • Hemoglobin\>/=8.0 g/dL
  • Platelets \>/=75,000/mm3
Reasons someone may not be able to joinExclusion criteria
  • Pregnant or lactating women
  • Any radiotherapy within 1 week of starting treatment on protocol.
  • Any major surgery within 1 weeks of starting treatment on protocol.
  • Any evidence of active clinically significant interstitial lung disease
  • Continue to have unresolved \> grade 1 toxicity from any previous treatment Treatment
  • Patients with a known mechanism of resistance to osimertinib that will clearly not respond to dacomitinib therapy (i.e. known MET amplification, ALK fusion, RET fusion).
  • Symptomatic brain metastases or leptomeningeal disease requiring escalating doses of steroids

Important: This is the sponsor’s public criteria, not a determination of eligibility. The study team must review your individual situation.
