Astra Zeneca (Immuno Stereotactic Ablative Body Radiotherapy) ISABR Study: Randomized Phase I/II Study of Stereotactic Body Radiotherapy
Stopped: Low accrual
United States, Australia18 participantsStarted 2017-10-11
Plain-language summary
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
. Written informed consent obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluation.
. 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.
. 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.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Phase I: The number and severity of study participants' treatment-related adverse events as assessed by CTCAE v4.0.
. Eastern Cooperative Oncology Group (ECOG) performance status of 0 - 1.
. Adequate normal organ and marrow function as defined below:
. 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.
Exclusion criteria
. ECOG Performance status \>1.
. Patients with metastatic or node positive NSCLC.
. Patients with prior radiation therapy to the same bronchopulmonary segment.
. History of automimmune disease including myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus erythematous, rheumatoid arthritis, inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis), vascular thrombosis associated with antiphospholipid syndrome, Wegner's granulomatosis, Sjogren's syndrome, Guillain-Barre syndrome, multiple sclerosis, or glomerulonephritis.
. Patients with history of idiopathic pulmonary fibrosis, idiopathic pneumonitis, drug induced pneumonitis, or evidence of active pneumonitis on screening chest CT scan.
. Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).
. Participation in another clinical study with an investigational product during the last 6 months.
. Any previous treatment with a Programmed Death-1 (PD1) or Programmed Death-Ligand 1(PD-L1) inhibitor, including durvalumab, and therapeutic anticancer vaccine.
