Outcome Measures

Primary Outcomes (1)

  • Overall Response Rate

    Overall response rate (partial and complete responses) of dacomitinib in participants with EGFR-mutant lung cancers and disease progression on osimertinib

    1 year

Secondary Outcomes (2)

  • Progression-free survival

    1 year

  • Overall survival

    1 year

Study Arms (2)

Cohort 1: Participants treated with dacomitinib alone

EXPERIMENTAL

Participants in this cohort have a somatic activating mutation in EGFR in a tumor biopsy or plasma cfDNA liquid biopsy.

Drug: Dacomitinib

Cohort 2: Participants treated with dacomitinib in combination with osimertinib

EXPERIMENTAL

Participants in this cohort have a secondary acquired EGFR mutation in addition to the sensitizing mutation

Drug: DacomitinibDrug: Osimertinib

Interventions

Cohort 1 Dacomitinib Dosing: Dose level 1: Dacomitinib 45mg daily Dose level -1: Dacomitinib 30mg daily Dose level -2: Dacomitinib 15mg daily Cohort 2 Dacomitinib Dosing: Dose level 1: Dacomitinib 30 mg daily Dose level -1: Dacomitinib 15 mg daily

Cohort 1: Participants treated with dacomitinib aloneCohort 2: Participants treated with dacomitinib in combination with osimertinib

In cohort 2, participants will begin on dacomitinib orally daily in combination with Osimertinib Dose level Osimertinib Dosing: Dose level 1: Osimertinib 80 mg daily Dose level -1: Osimertinib 40 mg daily

Cohort 2: Participants treated with dacomitinib in combination with osimertinib

  • 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
