Phase III Study to Determine the Efficacy of Durvalumab in Combination With Chemotherapy in Completely Resected Stage II-III Non-small Cell Lung Cancer (NSCLC)

Inclusion criteria

Patients must be capable of giving signed informed consent, which includes a mandatory genetic informed consent and compliance with the requirements and restrictions listed in the informed consent forms (ICFs) and in this protocol. Provision of signed and dated, written ICFs must occur prior to any mandatory study-specific procedures, sampling, and analyses.

In addition to ICF1 and ICF2, patients will provide signed and dated written optional genetic informed consent prior to collection of a sample for optional genetic analysis at the time of second screening (Table 2). This is different from the genetic samples and testing covered by ICF1, which are mandatory for participation in this study.

Criteria and procedures initiated with the signing of ICF1

• ICF1 must be signed and dated prior to any study procedures and prior to the planned surgical resection of the primary NSCLC, with the exceptions noted below. This consent will cover the study-specific first screening procedures outlined in Table 1.

Exception: Patients will be permitted to sign ICF1 up to Week 3 (Day 21) postsurgery. Patients identified after Week 3 post-surgery but prior to Week 5 (Day 35) post-surgery may be allowed to sign ICF1 depending on the outcome of the discussion with the study physician. In these cases, a whole blood sample and resected tumor tissue must be collected and sent to the diagnostic lab as soon as possible after ICF1 is signed for development of the personalized panel. A plasma sample must still be collected at Week 3-5 (Day 21-35) post-surgery, even if creation of the personalized panel for MRD detection is delayed.

Age

• Age ≥18 years at the time of screening. Sex
• Male and/or female. Type of patient and disease characteristics
• Individuals who have diagnosis of histologically confirmed NSCLC (WHO 2015 classification) with resectable (stage II-III) disease (according to IASLC Staging Manual in Thoracic Oncology v8.0). Select (ie, T3N2 or T4N2) stage IIIB patients will be eligible, provided that they are upstaged to T3N2 or T4N2 based on confirmed pathology. Patients who are staged asT3N2 or T4N2 prior to surgery are not eligible.
• A contrast-enhanced CT or MRI scan of the chest 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 (contrastenhanced or low-dose CT component) in order to rule out detectable extrathoracic, extracranial metastasis and to assess for potential mediastinal lymph node involvement prior to surgery. In the absence of pre-operative FDG-PET CT imaging, pre-operative contrast-enhanced CT imaging or MRI scan must cover liver and adrenal glands. If only CT is available, or FDG-PET reveals suspicious lymph node mediastinal involvement, it is recommended that invasive pre-operative mediastinal staging is performed according to the algorithm of the European Society of Thoracic Surgeons guidelines (algorithm to follow for primary mediastinal staging if only pre-operative CT is available [De Leyn et al 2007], algorithm to follow for primary mediastinal staging when PET-CT is available [De Leyn et al 2014]). It is preferred that imaging occurs within 6 weeks prior to surgery. Brain MRI (preferred) or brain CT with IV contrast is required for complete staging of the tumor.
• Complete resection of the primary NSCLC is mandatory. The primary tumor must be deemed resectable by a multidisciplinary evaluation that must include a thoracic surgeon certified or trained according to local standards and who performs lung cancer surgery as a significant part of their practice. Surgical resection of the 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. Note: Patien
