Inclusion Criteria
  • Histologically or cytologically documented N2 positive non-squamous NSCLC with resectable (Stage IIIA or T3-4N2 IIIB) disease (according to Version 8 of the IASLC Cancer Staging Manual [IASLC Staging Manual in Thoracic Oncology 2016]).
  • Complete surgical resection of the primary NSCLC must be deemed achievable, as assessed by a MDT evaluation (which should include a thoracic surgeon, specialized in oncologic procedures).
  • Eastern Cooperative Oncology Group (ECOG) PS of 0 or 1 at enrolment, with no deterioration over the previous 2 weeks prior to baseline or day of first dosing
  • A tumour which harbours one of the 2 common EGFR mutations known to be associated with EGFR-TKI sensitivity (Ex19del, L858R), either alone or in combination with other EGFR mutations (ie, T790M, G719X, Exon20 insertions, S7681 and L861Q).
Exclusion Criteria
  • Past medical history of ILD, drug-induced ILD, radiation pneumonitis which required steroid treatment, or any evidence of clinically active ILD.
  • History of another primary malignancy, except for the following: Malignancy treated with curative intent and with no known active disease ≥2 years before the first dose of investigational product (IP) and of low potential risk for recurrence; Adequately treated non-melanoma skin cancer or lentigo malignancy without evidence of disease; Adequately treated carcinoma in situ without evidence of disease
  • Patients who have pre-operative radiotherapy treatment as part of their care plan
  • Mixed small cell and NSCLC histology
  • T4 tumours infiltrating the aorta, the oesophagus and/or the heart; and/or any bulky N2 disease deemed unresectable
  • Patients who are candidates to undergo only segmentectomies or wedge resections
  • Prior treatment with any systemic anti-cancer therapy for NSCLC including chemotherapy, biologic therapy, immunotherapy, or any investigational drug
  • Prior treatment with EGFR-TKI therapy
  • Current use of (or unable to stop use prior to receiving the first dose of study treatment) medications or herbal supplements known to be strong inducers of cytochrome P450 (CYP) 3A4 (at least 3 weeks prior)

Primary Outcome Measures
NameTimeMethod
complete lymph node clearance rateFrom date of enrollment to an average of 12 weeks after the first dose

the ratio of ypN0 percentage after resection

Secondary Outcome Measures
NameTimeMethod
Major Pathological Response (MPR)From date of enrollment to an average of 12 weeks after the first dose

Defined as ≤10% residual cancer cells in the main tumour, as assessed per central pathology laboratory post-surgery

Disease free survival (DFS)From date of enrollment up to approximately 42 months after date of resection

DFS is defined as the time from the date of surgery until the first date of disease recurrence (local or distant) or date of death due to any cause, whichever occurs first.

DownstagingFrom date of enrollment to an average of 12 weeks after the first dose

Measured using pathologic mediastinal lymph node evaluation

Pathological complete response (pCR)From date of enrollment to an average of 12 weeks after the first dose

Defined as absence of any residual cancer cells in the dissected tumour samples, including the main tumour and lymph nodes, assessed post-surgery
