This is a Phase II open-label, single-arm, multicenter, international study to evaluate the
clinical activity of durvalumab in patients with Stage III unresectable NSCLC who are deemed
to be ineligible for chemotherapy per Investigator assessment. Patients will be enrolled into
2 cohorts according to radiotherapy pretreatment dose (Cohort A: standard radiation therapy
[60 gray (Gy) ± 10% or hypofractionated bioequivalent dose (BED)]; Cohort B: palliative
radiation therapy [40 to < 54 Gy or hypofractionated BED]).
This is a Phase II open-label, single-arm, multicenter, international study to evaluate the
clinical activity of durvalumab in patients with Stage III unresectable NSCLC who have an
Eastern Cooperative Oncology Group (ECOG) PS of 0 to 2 and who were treated with radiotherapy
but are ineligible for chemotherapy. Patients will be enrolled into 2 cohorts according to
the dose of radiotherapy received prior to study entry (Cohort A: Standard Radiotherapy [60
Gy ± 10% or hypofractionated BED]; Cohort B: Palliative Radiotherapy [40 to < 54 Gy or
hypofractionated BED]). Patients must not have progressed following radiation therapy, and
radiation therapy must be completed within 6 weeks (42 days) prior to first study drug
administration. The last dose of radiation therapy is defined as the day of the last
radiation treatment session. All patients will receive 1500 mg durvalumab via IV infusion
every 4 weeks (q4w) for up to a maximum of 12 months (up to 13 doses/cycles)
Inclusion Criteria:
1. Capable of giving signed informed consent.
2. Age ≥ 18 years at study entry.
3. Histologically or cytologically documented NSCLC with locally-advanced, unresectable
Stage III disease.
4. Deemed ineligible for chemotherapy per Investigator assessment.
5. Receipt of radiation therapy that was completed within 42 days prior to first study
drug administration.
6. Must have received a total dose of radiation of 40 to 66 Gy (standard or
hypofractionated BED).
7. Must not have progressed following radiation therapy, as per Investigator assessed
RECIST 1.1 criteria: a) Patients with measurable disease and/or nonmeasurable and/or
no evidence of disease assessed at baseline by computed tomography /magnetic resonance
imaging will be eligible for this study. b) Prior irradiated lesions may be considered
measurable and selected as target lesions (TLs) providing they fulfill the other
criteria for measurability.
8. World Health Organization/ECOG performance status of ≤2.
9. No prior exposure to immune-mediated therapy including, but not limited to,
anti-CTLA-4, anti-PD-1, anti-PD-L1, and antiprogrammed cell death ligand 2
(anti-PD-L2) antibodies, excluding therapeutic anticancer vaccines.
10. Patients must have adequate organ and marrow function as defined below:
- Hemoglobin ≥ 9.0 g/dL
- Absolute neutrophil count ≥ 1.0 × 109 /L
- Platelet count ≥ 75 × 109/L
- Serum bilirubin ≤ 1.5 × the upper limit of normal (ULN). This will not apply to
patients with confirmed Gilbert's syndrome.
- Alanine aminotransferase and aspartate aminotransferase ≤ 2.5 × ULN
- Measured creatinine clearance > 30 mL/min or calculated CL > 30 mL/min as
determined by Cockcroft-Gault
11. Life expectancy of greater than 12 weeks.
12. Body weight greater than 30 kg at study entry and at first study drug administration
Exclusion Criteria:
1. Patients with locally-advanced NSCLC whose disease has progressed following radiation
therapy.
2. Mixed small cell lung cancer and NSCLC histology.
3. History of allogeneic organ transplantation.
4. Active or prior documented inflammatory bowel disease (e.g., Crohn's disease,
ulcerative, systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome).
5. Uncontrolled intercurrent illness (e.g., ongoing or active infection, symptomatic
congestive heart failure, uncontrolled hypertension, unstable angina pectoris)
6. History of another primary malignancy except for (a) malignancy treated with curative
intent and with no known active disease ≥ 5 years before the first study drug
administration, (b) adequately treated nonmelanoma skin cancer or lentigo maligna
without evidence of disease, and c) treated carcinoma in situ without evidence of
disease.
7. History of leptomeningeal carcinomatosis
8. History of active primary immunodeficiency
9. Active infection including tuberculosis, hepatitis B, hepatitis C, or human
immunodeficiency virus
10. Any unresolved toxicity NCI CTCAE Grade ≥ 2 from previous anticancer therapy with the
exception of alopecia, vitiligo, lymphopenia, and the laboratory values defined in the
inclusion criteria
11. Known allergy or hypersensitivity to any of the study drugs or any of the study drug
excipients.
12. Receipt of live attenuated vaccine within 30 days prior to the first dose of
durvalumab
13. Major surgical procedure (as defined by the Investigator) within 28 days prior to the
first dose of durvalumab.
14. Current or prior use of immunosuppressive medication within 14 days before the first
dose of durvalumab.
15. Participation in another clinical study with an IP administered in the last 4 weeks.
16. Concurrent enrollment in another clinical study, unless it is an observational
(noninterventional) clinical study or during the follow-up period of an interventional
study
17. Prior randomization or treatment in a previous durvalumab clinical study regardless of
treatment arm assignment
18. Patients who refuse chemotherapy by their own decision.
19. Involvement in the planning and/or conduct of the study
20. Female patients who are pregnant or breastfeeding or male or female patients of
reproductive potential who are not willing to employ effective birth control.

22. Genetics research study (optional):
Exclusion criteria for participation in the optional genetics research component of the
study include: a) Previous allogeneic bone marrow transplant b)Nonleukocyte-depleted whole
blood transfusion within 120 days of genetic sample collection.
