Type of patient and disease characteristics
5. Histologically or cytologically documented NSCLC with resectable (Stage IIA to select [ie, N2] Stage IIIB) disease (according to Version 8 of the International Association for the Study of Lung Cancer Staging Manual in Thoracic Oncology).
i).At screening, complete surgical resection of the primary NSCLC must be deemed achievable, as assessed by a multidisciplinary evaluation, which must include a thoracic surgeon who performs lung cancer surgery as a prominent part of his/her practice.
ii).Nodal status should be investigated with whole body 18F-fluoro-deoxyglucose positron emission tomography (FDG-PET), plus contrast-enhanced computed tomography (CT) in addition to or in combination with PET before surgery. If PET/CT scan is positive in the mediastinum, or if scan is negative but there is T>3 cm, central tumor, or clinical N1 (cN1), then nodal status should be proven by biopsy via endobronchial ultrasound, mediastinoscopy, or thoracoscopy. (preoperative mediastinal lymph node staging).
iii).Mandatory brain magnetic resonance imaging (MRI; preferred) with IV contrast or brain CT with IV contrast at the time of staging.
6. World Health Organization (WHO)/ECOG PS of 0 or 1 at enrolment.
7. At least 1 lesion, not previously irradiated, that qualifies as a RECIST 1.1 target lesion (TL) at baseline. Tumor assessment by CT or MRI scan must be performed within 28 days prior to randomization.
8. No prior exposure to immune-mediated therapy including, but not limited to, other anti-CTLA-4, anti-PD-1, anti-PD-L1, and anti-PD-L2 antibodies, excluding therapeutic anticancer vaccines.
9. Adequate organ and marrow function as defined below:
i).Hemoglobin ≥9.0 g/dL
ii).Absolute neutrophil count ≥1.5 × 109/L
iii).Platelet count ≥100 × 109/L

vi).Measured creatinine clearance (CL) >40 mL/min or Calculated creatinine CL >40 mL/min as determined by Cockcroft-Gault (using actual body WT)
Males:
Creatinine CL is equal to WT (kg) × (140-Age) (mL/min) 72 × serum creatinine (mg/dL)
Females:
Creatinine CL is equal to WT (kg) × (140-Age) × 0.85(mL/min) 72 × serum creatinine (mg/dL)
10. Must have a life expectancy of at least 12 weeks.
11. Body WT >30 kg.
Sex
12. Male and/or female.
Tumor sample requirements:
13. Confirmation of a patient’s tumor PD-L1 status must occur prior to randomization using Ventana PD-L1 (SP263) immunohistochemistry (IHC) assay applied to formalin fixed paraffin embedded tissue sample with testing completed by the central laboratory.
Samples for PD-L1 testing may include the following:
i).Newly acquired tumor tissue (preferred) or archival tissue (<3 months old).
ii).If the patient’s PD-L1 status has already been assessed using the analytically validated Ventana assay as a part of the screening process for another AstraZeneca/MedImmune study, this test result can be used for the determination of eligibility.
14. Documented EGFR and ALK status (local testing is preferred; if not feasible, central testing will be performed). If the local laboratory will perform the test, a well-validated, local regulatory-approved kit must be used. EGFR/ALK status should be available prior to randomization. If the number of patients with EGFR or ALK mutations (ie, the total number of patients summed across both types of mutations) reaches approximately 20% of the total randomization target patient number, the incoming patients with EGFR/ALK
mutations will not be randomized.
Surgery eligibility (these criteria must be assessed within 30 days prior to surgery, following neoadjuvant treatment)
15. Surgery to be performed will be lobectomy, sleeve resection, bilobectomy, or pneumonectomy, as determined by the attending surgeon based on the intraoperative findings.
16. Received 4 cycles of platinum-based chemotherapy concurrent with durvalumab or placebo
i).Receipt of 3 cycles of platinum-based chemotherapy concurrent with durvalumab or placebo will be permitted only if the patient experienced chemotherapy related toxicities and Investigators judge additional safety issue will be expected with additional cycles of chemotherapy.
17. Surgery should happen within 40 days from the last IP administration.
18. Patients must have recovered from all acute, reversible toxic effects from chemotherapy (excluding alopecia) and durvalumab or placebo that could potentially adversely impact the surgical procedure or outcome according to the Investigator’s judgement.
19. A contrast enhanced CT/MRI scan of chest and abdomen (including the entire liver and both adrenals) are required for RECIST 1.1 assessment and for surgical planning prior to surgery. A supplemental (whole body) FDG-PET scan may also be acquired prior to surgery in order to help identify mediastinal lymph node involvement, according to investigators judgement.
20. If preoperative CT and/or PET are suspicious for mediastinal nodal involvement, or should those be negative for mediastinal lymph node but there is T>3 cm, cN1, or central tumor, then it is recommended that invasive mediastinal staging with thoracoscopy or mediastinoscopy or endobronchial ultrasound-guided transbronchial needle aspiration be performed if those were not performed at screening and/or according to the multidisciplinary evaluation and Investigator’s judgment.
21. Complete surgical resection of the primary NSCLC must be deemed achievable, as assessed by a multidisciplinary evaluation, which must include a thoracic surgeon who perform lung cancer surgery as a prominent part of his/her practice.
22. Deemed adequate cardiac and lung function, according to the multidisciplinary assessment. A pre- or post-bronchodilator forced expiratory volume in 1 second (FEV1) of 1.0 L or >40% postoperative predicted value and diffusing capacity of the lungs for carbon monoxide (DLCO) >40% predicted value is recommended.
Post-surgery durvalumab or placebo administration eligibility (these criteria must be assessed within 10 weeks from surgery, prior to starting adjuvant treatment)
23. Patients must have recovered from all acute, reversible toxic effects from previous treatments that could potentially adversely impact further administration of durvalumab or placebo according to the Investigator’s judgement.
24. Patients should be able to start durvalumab or placebo administration as soon as clinically feasible and within 10 weeks from surgery. A minimum of 3 weeks is recommended between NSCLC surgery and durvalumab/placebo treatment start (first post-surgical scan must be performed prior to starting adjuvant treatment). Complete post-operative wound healing must have occurred following any surgery.
25. Patients with N2 disease or patients with R1/2 post-surgical findings can receive adjuvant post-operative radiation therapy (within 8 weeks after surgery) and are eligible to receive post-surgery durvalumab/placebo (within 3 weeks from end of post-operative radiation therapy). The post-operative radiation therapy must be completed prior to durvalumab/placebo administration.

This is a Phase III, double-blind, placebo-controlled, multi-center international study of neoadjuvant/adjuvant durvalumab for the treatment of patients with resectable Stages II and III NSCLC.
Approximately 800 patients with resectable NSCLC (Stage IIA to select Stage IIIB; either squamous or non-squamous) will be randomized in a 1:1 ratio to receive either durvalumab plus platinum-based chemotherapy before surgery followed by durvalumab post-surgery or placebo plus platinum-based chemotherapy before surgery followed by placebo post-surgery.
Patients will be stratified by disease stage (Stage II versus Stage III) and by PD-L1 expression status (<1% versus ≥1%). The percentage of patients with EGFR/ALK mutations will be capped at approximately 20% of the patients randomized. Once the cap is reached, EGFR/ALK mutated patients will no longer be allowed to enter the study.
Patients will receive 4 cycles of durvalumab or placebo plus platinum-based chemotherapy (q3w) followed by surgery. Surgery may consist of lobectomy, sleeve resection, bilobectomy, or pneumonectomy as determined by the attending surgeon based on the intraoperative findings. Patients who are candidates to undergo only segmentectomies or wedge resections at eligibility assessment are not eligible for this study.
All patients must be staged and managed according to the National Comprehensive Cancer Network 2018 Guidelines (version 4).
An early safety evaluation by an IDMC will review the data from the first 40 patients across both treatment arms who have undergone surgery and had 21 days of follow-up, in order to assess perioperative mortality and surgery delays. Surgery is expected within 40 days from the last IP dose. The IDMC will then meet regularly at 6-month intervals to review the safety and tolerability of durvalumab plus chemotherapy as neoadjuvant regimen and of durvalumab post-surgery, until all patients across both treatment arms have undergone surgery and have had at least 6 months of follow-up. Safety reviews will be carried out by the IDMC in an unblinded manner. The IDMC will report back to the Sponsor with any recommendations regarding modifications to the study.
Patients should be able to start durvalumab or placebo administration following surgery as soon as clinically feasible and within 10 weeks from surgery (except for patients receiving post-operative radiation therapy, which must be started within 8 weeks after surgery; durvalumab/placebo must be given within 3 weeks from the end of post-operative radiation therapy). Patients randomized to receive durvalumab plus platinum-based chemotherapy prior to surgery will receive an additional 12 cycles of durvalumab 1500 mg q4w, while patients randomized to receive placebo plus platinum-based chemotherapy prior to surgery will receive an additional 12 cycles of placebo q4w.
Tumor evaluation using RECIST 1.1 will be conducted at screening (within 28 days prior to randomization); after the completion of neoadjuvant chemotherapy prior to surgery; every 12 weeks (q12w)±1 week (relative to the date of surgery) for the first year; every 24 weeks (q24w)±1 week (relative to the date of surgery) for years 2, 3, and 4; and then yearly (relative to the date of surgery) thereafter, until RECIST 1.1-defined radiological PD, consent withdrawal, or death. For patients who do not have surgery and therefore will not have a first post-surgical scan or adjuvant treatment, scans will be conducted q12w±1 week (relative to the date of the planned pre-surgery scan) for the first year; q24w±1 week (relative to the date of the pre-planned surgery) for years 2, 3, and 4; and then yearly (relative to the date of the pre-planned surgery) thereafter, until RECIST 1.1-defined radiological PD, consent withdrawal, or death.
