Informed consent
1 Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the ICFs and in this protocol.
2 Provision of signed and dated, written informed consent form prior to any mandatory study-specific procedures, sampling, and analyses.
i. ICF1 must be signed and dated prior to initiation of the first screening and surveillance activities.
ii. ICF2a must be signed and dated prior to initiation of the second screening activities and randomization.
iii. ICF2b must be signed and dated prior to initiation of the study-specific observation period and procedures.
3 Provision of signed and dated written optional genetic informed consent prior to collection of the optional sample for genetic analysis. This consent should be signed at the time of second screening. This optional sample and analyses are separate from the mandatory genetic testing consent included in ICF1.
4 Age ≥18 years at the time of screening.
5 Male and/or female.
6 Histologically confirmed NSCLC with resectable stage II-III disease (according to IASLC Staging Manual in Thoracic Oncology v8.0) who have undergone curative intent therapy (complete resection of the primary tumor ± neoadjuvant and/or adjuvant therapy) per SoC. Select stage IIIB (ie, T3N2 or T4N2) patients will be eligible, provided they are upstaged to T3N2 or T4N2 based on confirmed pathology after surgery. Patients who are staged as T3N2 or T4N2 prior to surgery are not eligible.
7 A contrast-enhanced CT/MRI scan of the chest and abdomen (including liver and adrenal glands) along with brain MRI (preferred) or brain CT with IV contrast must have been done for surgical planning prior to surgery. It is recommended that patients undergo combined FDG-PET (18F-Fluoro-deoxyglucose positron emission tomography) and CT scan (computerized tomography) within the 6 weeks prior to surgery in order to rule out detectable extrathoracic, extracranial metastasis and to assess for potential mediastinal lymph node involvement prior to surgery.
8 Complete resection of the primary NSCLC is mandatory. Invasive (pre-operative or intraoperative) exploration of hilar and mediastinal lymph nodes must have been performed to confirm primary tumor nodal status (prior to or after surgery). primary NSCLC can occur by open thoracotomy or by video-assisted thoracic surgery (VATs) and resection can be achieved by segmentectomy, lobectomy, sleeve resection, bilobectomy or pneumonectomy. Patients undergoing wedge resection are not eligible for this study.
9 Patients should have completed (or be undergoing) curative intent therapy (surgery ± neoadjuvant and/or adjuvant therapy; adjuvant therapy can include PORT) with exceptions noted below:
i. Patients who discontinue chemotherapy and/or PORT for toxicity prior to completion of all planned therapy are eligible.
ii. Patients who have not received any neoadjuvant and/or adjuvant chemotherapy, and meet all other eligibility criteria, may be eligible under the following circumstances:
iii. All patients who are eligible for adjuvant chemotherapy MUST be offered adjuvant chemotherapy.
iv. The patient has declined adjuvant chemotherapy, and in the opinion of the Investigator, this is the patient s final decision after receiving appropriate information and adequate time to make the decision. The patient s refusal of adjuvant chemotherapy must be documented.
v. If in the view of the Investigator, adjuvant chemotherapy is contraindicated due to an underlying intercurrent illness/laboratory abnormality, which is not considered reversible within a reasonable timeframe for the patient to be eligible for adjuvant therapy, which must be documented.
10 Confirmation of suitable biosamples for WES and central PD-L1 testing. Resected tumor tissue and whole blood samples must be provided to the diagnostic laboratory for WES of tumor and germline DNA, respectively as soon as possible following pathology confirmation. Samples must be sent no later than 1-2 weeks after completion of adjuvant therapy or 3-5 weeks after surgery (if no adjuvant therapy is given) for development of the Sponsor-approved personalized panel for MRD detection at a central reference laboratory. Germline sequencing of whole blood is mandatory. must also be provided for PD-L1 testing at a central reference laboratory (see inclusion criteria 15).
11 Post-adjuvant therapy or post-surgery (if no adjuvant therapy is given) CT scan of the chest and abdomen (including liver and adrenal glands) and brain MRI [preferred] or brain CT with IV contrast should be available to confirm no evidence of metastasis. If scans were not performed post-curative intent therapy, additional scans must be done prior to start of surveillance.
12 Consents to be accessible for q6w±3d plasma sample collection for MRD evaluation and for q12w±1w CT scans during the 96-week surveillance period.
13 The plasma sample that marks the start of surveillance must be collected 8±1 weeks after completion of adjuvant therapy (if administered) or 12±1 weeks after surgery (where adjuvant therapy is not given).
i. A patient who is determined to be MRD- based on analysis of this plasma sample (ie, MRD- at the start of surveillance) may continue in surveillance provided all other eligibility criteria are met.
ii. A patient who is determined to be MRD+ based on analysis of this plasma sample (ie, MRD+ at the start of surveillance) may be eligible for immediate randomization provided all other eligibility criteria are met.
iii. A patient who becomes MRD+ during surveillance is eligible to enter the second screening period and may be randomized in the study if all other eligibility criteria are met.
14 CT scan of the chest and abdomen (including liver and adrenal glands) and brain MRI [preferred] or brain CT with IV contrast performed within the 28 days ± 7 days prior to randomization to confirm no evidence of RECIST 1.1-defined disease recurrence and/or metastasis.
15 Known tumor PD-L1 status determined at a central reference laboratory testing service using a validated Ventana SP263 PD-L1 immunohistochemistry (IHC) assay prior randomization. Patients with unknown PD-L1 status are not eligible for the study.
16 WHO/Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1.
17 Complete post-operative wound healing must have occurred prior to randomization; patients must have recovered from all acute, reversible toxic effects from prior treatments (excluding alopecia) that could potentially adversely impact further administration of durvalumab/placebo according to the Investigator s judgment.
18 Must have recovered from all acute, reversible toxic effects from chemotherapy that could potentially adversely impact further administration of durvalumab or placebo according to the Investigator s judgment

ExclusionCriteria
Details
Diagnostic assessments
1 EGFR and/or ALK mutant as assessed either from the tumor biopsy taken prior to surgery or the resected tumor tissue. Testing must be performed using a well-validated, local regulatory-approved test. EGFR/ALK may be tested centrally if local testing is unavailable.
2 Mixed small cell and NSCLC histology.

Brief Summary
This is a Phase III, randomized, multicenter, double-blind, placebo-controlled
study to evaluate the efficacy and safety of durvalumab adjuvant therapy
compared to placebo in patients with stage II-III NSCLC who have undergone
curative intent therapy (complete resection ± neoadjuvant and/or adjuvant
therapy), who have no evidence of RECIST 1.1- defined disease recurrence, and
who become MRD+ during a 96-week surveillance period.
The study will screen approximately 1500 patients and randomize
approximately 284 MRD+ patients with stage II-III NSCLC (select Stage IIIB
[T3N2 or T4N2] patients) whose tumors are EGFR and ALK wild type, and who have
completed curative intent therapy. The study will be conducted in approximately
250 centers globally.
Approximately 284 MRD+
patients will be randomized 1:1 to treatment with Durvalumab monotherapy or
placebo every 4 weeks (q4w) intravenously (IV). Patients will be treated for up
to a total of 24 months (26 cycles), until disease recurrence, or until other specific
treatment discontinuation criteria are met (whichever comes first). This study
will be fully blinded
