Brief Summary:
This phase II trial studies how well osimertinib works in treating participants with stage I-IIIA Epithelial Growth Factor Receptor (EGFR) -mutant non-small cell lung cancer before surgery. Osimertinib may stop the growth of tumor cells by blocking mutant EGFR signaling in cancer cells.

Detailed Description:


I. To evaluate the efficacy of osimertinib as neoadjuvant therapy in patients with surgically resectable EGFR-mutant non-small cell lung cancer (NSCLC).


I. To evaluate the safety of osimertinib given as neoadjuvant therapy in early stage EGFR-mutant NSCLC participants.

II. To evaluate whether neoadjuvant osimertinib treatment increases the frequency of tumors that are unresectable due to adverse events or disease progression.

III. To evaluate secondary measures of clinical efficacy in early stage EGFR-mutant NSCLC patients treated with osimertinib induction therapy.


I. To evaluate long-term measures of efficacy in patients treated with osimertinib neoadjuvant therapy.

II. To explore tissue and cell-free biomarkers that may be predictive of response or primary resistance to osimertinib neoadjuvant therapy.


Participants receive osimertinib orally (PO) once daily (QD) on days 1-28. Treatment repeats every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. Patients then undergo surgical resection of their cancer.

After completion of study treatment, participants are followed up at 30 days then every 3 months for up to 1 year.

Arm Intervention/treatment
Experimental: Treatment (osimertinib)
Participants receive 80mg osimertinib orally, once a day (PO QD) on days 1-28. Treatment repeats every 28 days for a minimum of 1 cycle prior to surgery in the absence of disease progression or unacceptable toxicity. Investigators will have the option to give a second cycle of study drug prior to surgery if clinically indicated. Depending on the timing of the final scans, patients may ultimately receive up to two weeks additional therapy with study drug beyond end of cycle 1 (or cycle 2) while awaiting surgery. Patients then undergo surgical resection of their cancer. No treatment with the study drug will be given after surgery.

  • AZD-9291
  • Tagrisso

Procedure: Therapeutic Conventional Surgery
Undergo surgery

Primary Outcome Measures :
  1. Major pathological response rate (MPR) [ Time Frame: Up to 1 year ]
    Tumors that exhibit =< 10% viable tumor will meet the criteria for a major pathological response. MPR rate will be determined in patients who receive at least one dose of study drug and become ineligible for surgery either because of disease progression or adverse event will be deemed not to have achieved MPR. The major pathological response rate will be reported with 95% confidence intervals.

Secondary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: Up to 70 days ]
    The frequency and percentages of patients with a best overall response rate of complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD) determined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria and by investigator's assessment will be determined from the time of treatment until surgery. The frequency and percentages of patients with a best ORR of CR, PR, SD, or PD will be determined. The ORR will be reported with 95% confidence intervals.

  2. Mean Disease-free survival (DFS) [ Time Frame: Up to 5 years ]
    DFS will be calculated as 1+ the number of days from date of surgical resection to documented radiographic relapse/progression or death due to any cause over a period of 60 months. The Kaplan-Meier analysis will be used to calculate the median DFS with 95% confidence interval.

  3. Disease-free survival rate (DFS) [ Time Frame: Up to 5 years ]
    DFS will be calculated as 1+ the number of days from date of surgical resection to documented radiographic relapse/progression or death due to any cause over a period of 60 months. The 5-year DFS rate will be calculated as the percentage of patients who are disease free at 5 years. This will be calculated using the Kaplan-Meier method

  4. Overall survival (OS) [ Time Frame: Up to 5 years ]
    5-year OS rate will be calculated using the Kaplan-Meier method . OS will be defined as the 1+ the number of days from surgical resection to death due to any cause over a period of 60 months. The Kaplan-Meier analysis will be used to calculate the median OS with 95% confidence interval.

  5. Depth of response (DpR) [ Time Frame: Up to 1 year ]
    DpR will be defined as the percentage change in tumor burden by RECIST criteria at best response versus baseline imaging. DpR will be summarized using descriptive statistics and correlated with patient outcomes using hazard ratios via the Cox proportional hazards model.

  6. Pathologic complete response rate (pCR) [ Time Frame: Up to 1 year ]
    The pCR is defined as absence of (0%) viable tumor present histologically in the resected tumor specimen

  7. Number of Treatment-emergent adverse events (AEs) [ Time Frame: Up to 1 year ]
    Treatment-emergent adverse events will be classified according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

  8. Percentage of participants unable to undergo surgical resection [ Time Frame: Up to 70 days ]
    Rate of conversion from operable to non-operative will be recorded as rate of patients initially assessed as surgically resectable, who are subsequently unable to undergo surgical resection due to either treatment-related adverse events (AEs) or disease progression.

  9. Percentage of surgical complications [ Time Frame: Up to 1 year ]
    Rate of surgical complications occurring prior to the end of treatment visit will be reported
