Intranasal, inhaled or topical steroids, and adrenal replacement steroid doses >10mg daily oral prednisone equivalent, are permitted in the absence of active autoimmune disease. 14. Positive test for hepatitis B surface antigen (HBsAg) indicating acute or chronic infection. Participants with a past or resolved HBV infection (defined as the presence of anti-HBc and absence of HBsAg) are eligible. 15. Positive test for hepatitis C virus antibody (HCV antibody) , unless polymerase chain reaction is negative for HCV RNA. 16. History of other significant, or active, infection, including HIV or tuberculosis (TB). HIV testing is not mandatory unless clinically indicated. Clinical evaluation for active TB may include clinical history, physical examination and radiographic findings, or tuberculosis testing in line with local practice. 17. Receipt of a transplanted solid organ (kidney, liver, heart or lung) or of an allogeneic bone marrow transplant. 18. Receipt of a live attenuated vaccine within 30 days prior to registration. 19. Use of alternative or traditional medicines within 14 days prior to registration. 20. Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring adverse events or compromise the ability of the patient to give written informed consent. 21. Pregnancy, lactation, or inadequate contraception. Women must be post-menopausal, infertile, or use a reliable means of contraception to avoid pregnancy for 90 days after the last dose of durvalumab. Women of childbearing potential must have a negative pregnancy test within 24 hours prior to trial registration. Men must have been surgically sterilized or use a double barrier method of contraception if they are sexually active with a woman of childbearing potential for a period of 180 days after the last dose of durvalumab and chemotherapy, or 90 days after the last dose of durvalumab monotherapy (whichever is the longer time period). Sperm donation is not permitted for 180 days after the last dose of durvalumab and chemotherapy, or 90 days after the last dose of durvalumab monotherapy (whichever is the longer time period). |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Progression free survival rate is the proportion of patients alive and progression free (the cancer has not worsened) assessed by CT Scan and clinical review. | The interval from the date of participant registration to the date of a progression free survival event:
date of the first CT scan to show disease progression patient is judged to have progressed by the responsible investigator (in the event that no RECIST assessment is available) death occurs. |
6 months | |
Secondary | Duration of dysphagia relief | Maintenance of Mellow score at least 1 point above baseline. Mellow score may be optionally assessed at days 22, 36 and 50 if the participants attend the clinic for any other unscheduled visit. Mellow score ranges from grade 0-4. Grade 0 indicating no dysphagia and grade 4 indicating inability to swallow. | Mellow score will be assessed at days 1, 8, 15, 29, 43, 57 and then every 4 weeks thereafter until the end of treatment visit (30days after the last dose). | |
Secondary | Nutritional status | Determined by clinical review and collected from the participant using the scored Patient-generated subjective global assessment (PG_SGA) tool. | To be administered by a qualified dietician from date of randomisation until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 96 weeks. | |
Secondary | Quality of life change using the - European organisation for the research and treatment of cancer quality of life questionnaire QLQ-C30 | Assessment of European organisation for the research and treatment of cancer quality of life questionnaire QLQ-C30 | Through study completion, an average of 1 year, using the 4-point ordinal scale - not at all, a little, quite a bit and very much | |
Secondary | Quality of life change using the - European organisation for the research and treatment of cancer quality of life questionnaire QLQ-OES18 | Assessment of European organisation for the research and treatment of cancer quality of life questionnaire QLQ-OES18 | Through study completion, an average of 1 year, using the 4-point ordinal scale - not at all, a little, quite a bit and very much | |
Secondary | Response rate in metastatic lesions | Assessed using radiological imaging with Contrast Cat Scan (chest and abdomen, + neck) | Assessment with imaging scans is performed at baseline then every 6 weeks while in treatment, then every 12 weeks until disease progression or date of death from any cause, whichever came first, assessed up to 96 weeks. | |
Secondary | Physician graded toxicity | Adverse events will be graded using the NCI Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. | Assessed from baseline to 90 days following last treatment dose. | |
Secondary | SAE Rate | Assessed as reported by the participant and by clinician assessment from consent signing to 100 days after last dose durvalumab regardless of relationship to drug. Adverse events will be documented in the patient medical record. A serious adverse event (SAE) is any untoward medical occurrence that at any dose: 1) results in death, 2) is life-threatening (i.e. the participant is at risk of death at the time of the event), 3) requires inpatient hospitalisation or prolongation of existing hospitalisation, 4) results in persistent or significant disability or incapacity, 5) is a congenital anomaly/birth defect, 6) other important medical events which may jeopardize the patient or may require intervention to prevent one of the listed outcomes in the definition above, which, in the opinion of the Investigator, are likely to become serious if untreated. | Days 1, 8, 15, 29, 43, 57 and then every 4 weeks thereafter until to 100 days after last dose durvalumab regardless of relationship to drug. | |
Secondary | Overall survival. | Overall survival will be reported with Kaplan Meier curves and summarized by their medians, and proportions event-free | Throughout study completion, average 2 years |
