Durvalumab (MEDI4736) With or Without SBRT in Clinical Stage I, II and IIIA Non-small Cell Lung Cancer

This is a randomized open label phase II trial of preoperative anti-PD-L1 antibody durvalumab
with or without concurrent non-ablative radiation followed by surgical resection and
postoperative monthly maintenance durvalumab for twelve months.

Inclusion Criteria

1. Patient has histologically or cytologically proven clinical stages I (tumors > 2 cm),
II, and IIIA NSCLC and is considered eligible for surgical resection with curative
intent. Patients with 2 primary non-small cell lung cancers are allowed.

2. Measureable disease, as defined by RECIST v1.1.

3. Written informed consent and HIPAA obtained from the subject prior to performing any
protocol-related procedures.

4. Age > 18 years at time of study entry

5. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

6. Adequate normal organ and marrow function as defined below:

- Haemoglobin ≥ 9.0 g/dL

- Absolute neutrophil count (ANC) ≥ 1.5 x 109/L (> 1500 per mm3)

- Platelet count ≥ 100 x 109/L (>100,000 per mm3)

- Serum bilirubin ≤ 1.5 x institutional upper limit of normal (ULN). This will not
apply to subjects with confirmed Gilbert's syndrome (persistent or recurrent
hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis
or hepatic pathology), who will be allowed only in consultation with their
physician.

- AST (SGOT)/ALT (SGPT), and alkaline phosphatase ≤ 2.5 x institutional upper limit
of normal (ULN).

- Serum creatinine CL>40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault
1976) or by 24-hour urine collection for determination of creatinine clearance:

7. Evidence of post-menopausal status or negative urinary or serum pregnancy test for
female pre-menopausal patients. Women will be considered post-menopausal 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 post-menopausal 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
post-menopausal range for the institution or underwent surgical sterilization
(bilateral oophorectomy or hysterectomy).

Women ≥50 years of age would be considered post-menopausal if they have been
amenorrheic 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 hysterectomy).

8. 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.

9. No prior therapy for their lung cancer.

Exclusion Criteria

Subjects should not enter the study if any of the following exclusion criteria are
fulfilled:

1. Participation in another clinical study with an investigational product during the
last 3 weeks.

2. History of another primary malignancy except for:

- Malignancy treated with curative intent and with no known active disease ≥3 years
before the first dose of study drug and of low potential risk for recurrence.

- Adequately treated non-melanoma skin cancer or lentigo maligna without evidence
of disease.

- Adequately treated carcinoma in situ without evidence of disease eg, cervical
cancer in situ, in-situ urinary bladder cancer , treated localized prostate
cancer and ductal carcinoma-in situ.

- Indolent hematological malignancies

3. Current or prior use of immunosuppressive medication within 14 days before the first
dose of durvalumab, with the exceptions of intranasal,inhaled, topical steroids, or
local steroid injections (e.g., intra articular injection), corticosteroids or
systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of
prednisone, or an equivalent corticosteroid, and steroids as premedication for
hypersensitivity reactions (e.g., CT scan premedication).

4. Any unresolved toxicity (CTCAE grade 2) from therapy for a prior malignancy with the
exception of alopecia, vitiligo, and the laboratory values defined in the inclusion
criteria.

- Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after
consultation with the Study Physician.

- Subjects with irreversible toxicity that is not reasonably expected to be
exacerbated by the investigational product may be included (e.g., hearing loss,
peripherally neuropathy).

5. Any prior Grade ≥3 immune-related adverse event (irAE) while receiving any previous
immunotherapy agent, or any unresolved irAE >Grade 1.

6. Active or prior documented autoimmune or inflammatory disorders (including
inflammatory bowel disease [e.g., colitis or Crohn's disease systemic lupus
erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with
polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc]). No
active diverticulitis within the previous 3 months. The following are exceptions to
this criterion:

- Patients with vitiligo or alopecia

- Patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on
hormone replacement

- Any chronic skin condition that does not require systemic therapy

- Patients without active disease in the last 5 years may be included but only
after consultation with the study physician

- Patients with celiac disease controlled by diet alone

7. Active or prior documented inflammatory bowel disease (e.g., Crohn's disease,
ulcerative colitis).

8. History of active primary immunodeficiency.

9. History of allogeneic organ transplant.

10. History of hypersensitivity to durvalumab or any excipient.

11. Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable
angina pectoris, cardiac arrhythmia, serious chronic gastrointestinal conditions
associated with diarrhea, or psychiatric illness/social situations that would limit
compliance with study requirement, substantially increase risk of incurring AEs or
compromise the ability of the patient to give written informed consent.

12. Active infection including tuberculosis (clinical evaluation that includes clinical
history, physical examination and radiographic findings, and TB testing in line with
local practice), hepatitis B (known positive HBV surface antigen (HBsAg) result),
hepatitis C, or human immunodeficiency virus (positive HIV 1/2 antibodies). Patients
with a past or resolved HBV infection (defined as the presence of hepatitis B core
antibody [anti-HBc] and absence of HBsAg) are eligible. Patients positive for
hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative
for HCV RNA.

13. History of leptomeningeal carcinomatosis.

14. Receipt of live attenuated vaccination within 30 days prior to study entry or within
30 days of receiving durvalumab.

15. Female patients who are pregnant or breastfeeding or male or female patients of
reproductive potential who are not willing to employ effective birth control from
screening to 90 days after the last dose of durvalumab monotherapy.

16. Any condition that, in the opinion of the investigator, would interfere with
evaluation of study treatment or interpretation of patient safety or study results

17. Subjects with uncontrolled seizures.

18. History of interstitial lung disease, idiopathic pulmonary fibrosis, pneumonitis
(including drug induced), or evidence of active pneumonitis on screening chest CT
scan.

19. Major surgical procedure within 28 days prior to Cycle 1, Day 1 or anticipation of
need for a major surgical procedure during the course of the study.

20. Receipt of the last dose of therapy (chemotherapy, immunotherapy, endocrine therapy,
targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies, or
other investigational agent) for an accepted other malignancy as defined in Section
3.3.2 within 30 first dose of study drug for lung cancer.

21. Prior randomisation or treatment in a previous durvalumab clinical study regardless of
treatment arm assignment.
