• 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:

• Centrally located tumours

• No regional or distant metastases are allowed (i.e. no stage II-IV disease)

• Oxygen usage or a FEV1 < 0.7 L and CO diffusion capacity < 30%

• Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site). Previous enrollment in the present study

• Participation in another clinical study with an investigational product during the last 4 weeks

• Any previous treatment with a PD1 or PD-L1 inhibitor, including durvalumab

• Second primary residual malignancy. Other malignancy diagnosed and treated > 5 years ago without relapse is allowed. (Carcinoma in situ of the cervix or adequately treated basal cell carcinoma of the skin < 5 years are allowed)

• Receipt of the last dose of anti-cancer therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies, other investigational agent) 28 days prior to the first dose of study drug

• Mean QT interval corrected for heart rate (QTc) ≥470 ms calculated from 3 electrocardiograms (ECGs) using Frediricia's Correction

• 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

• Active or prior documented autoimmune or inflammatory disorders . 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

• History of primary immunodeficiency

• History of allogeneic organ transplant

• History of hypersensitivity to durvalumab or any excipient

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure (NYHA III-IV), uncontrolled hypertension, unstable angina pectoris, interstitial lung disease, cardiac arrhythmia, active peptic ulcer disease, active bleeding diatheses

• 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). Subjects with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody [anti-HBc] and absence of HBsAg) are eligible. Subjects positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA

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

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

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