Brief Summary
Patients with cancer are increasingly being treated with drugs designed to modulate the response of their immune system, broadly to boost their body's defences against cancer. However, there is an unmet need to identify which patients are unlikely to benefit. Deciding on benefit from therapy uses standard imaging methods (e.g. CT scans), which can take time (months) whereas DNA in the bloodstream could be measured more rapidly. The main aim of this study is to assess whether changes in the level of circulating tumour DNA (ctDNA) can quickly determine a patients response. This would enable patients to change therapies more quickly if they are not responding and reduce exposure to unnecessary side effects.

Study Arms (1)
Durvalumab
EXPERIMENTALPatients with advanced oesophageal cancer will be administered with 1500mg of durvalumab once every 4 weeks for up to 6 months.
Interventions
Durvalumab will be administered via an infusion in the arm, over a duration of up to 1 hour.
Eligibility Criteria
You may qualify if:
- Provide written, informed consent to participate
- Aged ≥ 18 years at time of consent
- Confirmed advanced oesophageal cancer for which the patient must have received at least one prior line of standard of care treatment
- Predicted life expectancy ≥ 3 months
- Eastern Cooperative Oncology Group (ECOG) PS 0 or 1
- Measurable disease, as defined by RECIST v1.1.
- In the investigator's opinion, have an accessible and biopsiable tumour lesion for additional research biopsy, to which the patient will have to consent at screening.
- Adequate hematologic and organ function, defined by:
- ANC ≥ 1500 cells/μL (no GCSF support 2 weeks prior to trial entry)
- Platelet count ≥ 100,000/μL
- Haemoglobin ≥ 9.0 g/dL
- AST or ALT ≤ 2.5 times the upper limit of normal (ULN), (except patients with documented liver metastases where AST and/or ALT can be ≤ 5×ULN)
- Serum bilirubin ≤1.5 × ULN. (Except patients with confirmed Gilbert's syndrome)
- INR and APTT ≤ 1.5×ULN.
- Calculated creatinine clearance (CrCl) ≥ 40 mL/min (Cockcroft-Gault formula)
- +1 more criteria
You may not qualify if:
- Weight of ≤30kg
- Any concurrent chemotherapy, immunotherapy, biologic or hormonal therapy for cancer treatment.
- Participation in other clinical trials involving active treatment for the malignant disease.
- Received radiotherapy treatment on a wide body field, or an equivalent to more than 30% of the bone marrow, within the last 4 weeks.
- Any unresolved symptom NCI CTCAE Grade ≥2 from previous anticancer therapy (with the exception of alopecia and vitiligo).
- Active or prior documented autoimmune or inflammatory disease (except vitiligo) within the last 3 years, for example:
- Intestinal: Inflammatory Bowel Disease (Colitis, Crohn's Disease), Diverticulitis (with the exception of Diverticulosis), Coeliac Disease, Irritable Bowel Disease
- Vascular: any type of Vasculitic disorder, i.e.: Wegner syndrome.
- Endocrine: any endocrine alteration related to an auto-immune process i.e.: Hashimoto syndrome. NOTE: patients with hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement treatment may be included at the discretion of the CI.
- Respiratory: Active Pneumonitis (of any origin: inflammatory or infectious), Sarcoidosis.
- Dermatological: Psoriasis, Lupus/SLE.
- Other: Rheumatoid Arthritis, Hypophysitis, Uveitis.
- History of organ transplant that requires use of immunosuppressive medications or any medical condition in which immunosuppressive agents were administered, including but, not limited to:
- Systemic corticosteroids.
- Methotrexate, azathioprine
