durvalumab (medi4736) with or without sbrt in clinical stage i, ii and iiia non-small cell lung cancer

Conditions: Carcinoma, Non-Small-Cell Lung

Summary: the purpose of this study is to find out the effectiveness of the drug durvalumab (medi4736) with or without stereotactic body radiation therapy (sbrt) as treatment for stage i (tumors \> 2cm), ii, and iiia non-small cell lung cancer (nsclc) prior to surgery and one year following surgery.

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, following standard of care postoperative therapy.

Eligibility criteria:
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.
