In the preoperative period, patients who have undergone adequate mediastinal evaluation and
are considered operable will be treated with durvalumab 1125 mg IV every 3 weeks (Q3W) in
combination with platinum doublet chemotherapy (cisplatin with pemetrexed or docetaxel,
depending upon histology).
Patients will undergo postoperative radiation (54Gy) within 4-10 weeks after surgery (unless
single station N2 at registration with resultant ypT0N0 after neoadjuvant therapy).
One to 6 weeks after completion of radiation, patients will receive adjuvant durvalumab 1500
mg IV every 4weeks (Q4W) for 1 year.
Patients who do not have surgery due to refusal, physician decision, or local and distant
progression will have to discontinue study treatment.
All participants will have imaging assessment prior to surgery after Cycle 2 (Week 6) and
after Cycle 4 (Weeks 13 15). Patients will undergo potentially curable surgery as per
standard of care.
Patients will undergo imaging assessment every 12 weeks after surgery for 2 years, then every
6 months for 3 years.
1. ECOG Performance Status 0-1.
2. Absence of major associated comorbidities that increase the surgery risk to an
3. Pulmonary function capacity capable of tolerating the proposed lung resection. FEV1 at
least 2 L. If less than 2 L, the predicted postoperative forced expiratory volume in 1
second (FEV1) must be >0.8 L or be >35% of the predicted value. Postoperative
predicted DLCO ≥35% is required.

4. Patients with potentially resectable IIIA/B (T1-3, N2) NSCLC (per the 8th
International Association for the Study of Lung Cancer classification) who are
candidates for surgery with intent of R0 resection. Invasive T3 disease (eg, phrenic
nerve, pericardium, chest wall other than Pancoast superior sulcus) may be included if
the surgeon and study team deem it to be resectable. T4 disease per AJCC 8th edition
staging system is excluded given the lack of benefit of surgery in T4N2.
5. Patients must be evaluated by a thoracic surgeon within 4 weeks of registration.
6. Operability is defined as having adequate pulmonary, cardiac, renal, nutritional,
musculoskeletal, neurologic, and cognitive capacity to undergo major pulmonary
resection with acceptable morbidity and mortality.
7. N2 nodes must be discrete (ie, not invading surrounding structures) and less than 3 cm
in maximum diameter.
8. Measurable disease according to Response Evaluation Criteria in Solid Tumors version
1.1 (RECIST v1.1).
9. Pathologically proven N2 disease within 4 weeks of registration. PET/CT positivity in
the ipsilateral mediastinal nodes will not be sufficient to establish N2 nodal status.
Mediastinal lymph node sampling biopsy is required pre-operatively by at least one of
- Endobronchial Ultrasound Transbronchial Needle Aspiration (EBUS-TBNA);
- Mediastinotomy (Chamberlain procedure);
- Endoscopic ultrasound guided node aspiration (EUS);
- Video-assisted thoracoscopy; OR
- Fine needle aspiration by image guidance.
- Endobronchial ultrasound (EBUS) or mediastinoscopy or other tissue sampling (at
least 2 stations must be biopsied, with at least one station positive for N2
disease). If there are any mediastinal nodes suspicious by CT (>1.5 cm) or PET in
N3 stations, they must be biopsied. If biopsy proven involvement in an N3
station, the patient is excluded.
10. Mediastinal nodal biopsy or aspiration can only be omitted in the special circumstance
in which ALL of the following are true:
- The tumor is left sided;
- The only mediastinal nodal involvement is a node visible in the AP (level 5)
region on CT scan;
- Distinct primary tumor separate from the nodes; AND
- Biopsy proven non-small cell histology from the primary tumor.
11. No prior history of thoracic radiation.
12. Organ and marrow function definitions (example below)
- leukocytes ≥3,000/mcL
- absolute neutrophil count ≥1,500/mcL
- platelets ≥100,000/mcL
- Hemoglobin >9.0 g/dL
- total bilirubin within normal institutional limits
- AST(SGOT)/ALT(SGPT) ≤2.5 × institutional upper limit of normal
- creatinine within normal institutional limits OR
- creatinine clearance ≥60 mL/min/1.73 m2 for participants with creatinine levels
above institutional normal.
13. Patients are capable of giving informed consent and/or have an acceptable surrogate
capable of giving consent on the subject's behalf.
14. Nonpregnant and non-nursing. The effect of durvalumab on the fetus is unknown.
15. Women of childbearing potential (WOCBP) must be willing to use 2 methods of birth
control or be surgically sterile, or abstain from heterosexual activity for the course
of the study through 3 months after the last dose of study medication. Patients of
childbearing potential are those who have not been surgically sterilized or have not
been free of menses >1 year.
16. Evidence of postmenopausal status or negative urinary or serum pregnancy test for
female premenopausal patients. Women will be considered postmenopausal if they have
been amenorrheic for 12 months without an alternative medical cause. The following
age-specific requirements apply:
- Women <50 years of age would be considered postmenopausal if they have been
amenorrheic for 12 months or more following cessation of exogenous hormonal
treatments and if they have luteinizing hormone and follicle-stimulating hormone
levels in the postmenopausal range for the institution or underwent surgical
sterilization (bilateral oophorectomy or hysterectomy).
- Women ≥50 years of age would be considered postmenopausal if they have been
amenorrheic for 12 months or more following cessation of all exogenous hormonal
treatments, had radiation-induced menopause with last menses >1 year ago, had
chemotherapy-induced menopause with last menses >1 year ago, or underwent
surgical sterilization (bilateral oophorectomy, bilateral salpingectomy, or
