Randomized Phase I/II Study of Ablative Radiotherapy +/- MEDI 4736 (Durvalumab) for Medically Inoperable Early-Stage Non-Small Cell Lung Cancer

17-000004

This study uses durvalumab (MEDI 4736), an experimental type of drug made by Astra Zeneca Pharmaceuticals, (limited partnership) LP, which in early studies has shown to possibly reduce the growth of certain types of lung cancer. The Investigators will enroll up to 105 subjects into the study. After an initial safety sample of 15 individuals receiving durvalumab (MEDI 4736) and Stereotactic Ablative Body Radiotherapy (SABR), if it is shown to be safe to administer this combination of therapies, the next enrolled subjects will be randomized in a 1:1 fashion (each subject with a "50-50 chance" like the flip of a coin) to receive either SABR and durvalumab (MEDI 4736), or SABR alone. Once treatment is completed, all subjects will return to the University of California at Los Angeles (UCLA) for regular follow-up visits to check on their health and outcomes. At visits both prior to and after treatment special blood samples will be drawn to be studied by UCLA scientists to look into the basic science aspects of how durvalumab (MEDI 4736) and radiation work in the body. It is hoped that we will learn more about the basic safety and science of durvalumab (MEDI 4736) combined with Stereotactic Ablative Body Radiotherapy (SABR) vs. SABR alone, while extending the life and quality of life of these subjects.

Inclusion Criteria: For inclusion in the study subjects must fulfill all of the following criteria: 1. Written informed consent obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluation. 2. Newly diagnosed, untreated, biopsy proven non-small cell lung cancer. 3. Medically inoperable or patient refusal to surgery as defined by any single of the following criteria: a. Determined unfit for surgery by thoracic surgeon or radiation oncologist as documented in the medical record b. Pulmonary function test (PFTS) showing Forced Expiratory Volume in the first second (FEV1) ≤ 1.2 L or diffusing Lung Capacity (DLC) \<60%, c. Poor exercise tolerance or failed pre-operative cardiac work-up, d. Patient refusal to undergo definitive surgery as documented in clinical note by a surgeon, pulmonologist, medical oncologist, or radiation oncologist. 4. Clinically stage I disease by American Joint Committee on Cancer (AJCC) 7th edition. (N0, M0, T stages T1-T2a) or patients with stage T2bN0M0 (clinical stage IIA) disease who are medically unfit for standard of care chemotherapy as documented by a medical oncologist or radiation oncologist, or who refuse standard of care chemotherapy as documented by a medical oncologist or radiation oncologist. 5. Age \> 18 years at time of study entry. 6. Eastern Cooperative Oncology Group (ECOG) performance status of 0 - 1. 7. 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.\>\> * aspartate aminotransferase (AST) serum glutamic oxaloacetic transaminase (SGOT)/ alanine aminotransferase (ALT) serum glutamic pyruvic transaminase (SGPT) ≤ 2.5 x institutional upper limit of normal unless liver metastases are present, in which case it must be ≤ 5x ULN. * Serum creatinine creatinine clearance (CL) \>40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance: Males: Creatinine CL (mL/min) = Weight (kg) x (140 - Age) . 72 x serum creatinine (mg/dL) Females: Creatinine CL (mL/min) = Weight (kg) x (140 - Age) x 0.85 72 x serum creatinine (mg/dL) 8. Female subjects must either be of non-reproductive potential (i.e. post-menopausal by history: ≥60 years old and no 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: 1. ECOG Performance status \>1. 2. Patients with metastatic or node positive NSCLC. 3. Patients with prior radiation therapy to the same bronchopulmonary segment. 4.

However, patients with type 1 diabetes mellitus, vitiligo, alopecia, hypothyroidism requiring hormone replacement, Graves disease, or skin disorders not requiring systemic treatment are permitted to enroll. 5. Patients with history of idiopathic pulmonary fibrosis, idiopathic pneumonitis, drug induced pneumonitis, or evidence of active pneumonitis on screening chest CT scan. 6. Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site). 7.
