concurrent neoadjuvant chemoradiotherapy plus durvalumab (medi4736) in resectable stage iii nsclc

Conditions: Potentially Resectable Stage II/IIIa NSCLC

Summary: combination treatment of durvalumab with chemoradiotherapy is ongoing for head/neck cancer, renal cell carcinoma, melanoma, and non-small cell lung cancer (nct02318771) and pancreatic cancer (nct02305186).combining durvalumab with neoadjuvant chemoradiotherapy is a promising strategy to improve clinical outcome in stage iii lung cancer. using serial biopsied and surgically resected fresh tissue through the novel/high-throughput rna sequencing technologies, we want to identify the change immune signature in tumor microenvironment of nsclc patients after durvalumab treatment. with hypothesis that pd-1 inhibitor as a component of neoadjuvant chemoradiotherapy followed by surgery could increase complete pathologic response rate and disease free survival, and overall survival, we suggest adding durvalumab to neoadjuvant chemoradiation in stage ii/iii resectable nsclc. and with immune marker study using facs, whole exome sequencing, or rnasequencing, we can find the potential predictive biomarker for anti-pd-l1 blockade. and in this study, we can get "whole" surgical specimen not biopsy sample after durvalumab treatment so the analysis for immune marker, tumor microenvironment, and various tumor infiltrating immune cells and their changes will be available.

menses for 1 year without an alternative medical cause; or history of hysterectomy, or history of bilateral tubal ligation, or history of bilateral oophorectomy) or must have a negative serum pregnancy test upon study entry. 9. subject is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up. exclusion criteria: subjects should not enter the study if any of the following exclusion criteria are fulfilled: 1. patients with metastatic lesions or clinical n3 lymph nodes 2. participation in another clinical study with an investigational product during the last 60 months 3. involvement in the planning and/or conduct of the study (applies to both astrazeneca staff and/or

pd-l1 inhibitor, including durvalumab 6. history of leptomeningeal carcinomatosis 7. brain metastases or spinal cord compression. subjects with suspected brain metastases at screening should have an mri (preferred) or ct each preferably with iv contrast of the brain prior to study entry 8. receipt of the last dose of anti-cancer therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies, other investigational agent) ≤ 36months prior to the first dose of study drug 9. mean qt interval corrected for heart rate (qtc) ≥470 ms calculated from 3 electrocardiograms (ecgs) using frediricia's correction 10. current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid 11. current or prior use of immunosuppressive medication within 14days (use 28 days if combining durvalumab with a novel agent) before the first dose of durvalumab, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid. the following are exceptions to this criterion: * intranasal, inhaled, topical steroids, or local steroid injections (eg, intra articular injection) * systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent * steroids as premedication for hypersensitivity reactions (eg, chemotherapy, ct scan premedication) 12. any concurrent chemotherapy, ip, biologic, or hormonal therapy for cancer treatment. concurrent use of hormonal therapy for non-cancer-related conditions (eg, hormone replacement therapy) is acceptable. 13. history of allogeneic organ transplant 14. active or prior documented

sarcoidosis syndrome, or wegener syndrome \[granulomatosis with polyangiitis, graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc\]). the following are exceptions to this criterion: * subjects with vitiligo or alopecia * subjects with hypothyroidism (eg, following hashimoto syndrome) stable on hormone replacement * any chronic skin condition that does not require systemic therapy * subjects without active disease in the last 5 years may be included but only after consultation with the study physician * subjects with celiac disease controlled by diet alone 15. uncontrolled
