| Scientific title | Addition of stereotactic body radiotherapy to systemic chemotherapy in locally advanced biliary tract cancers |
| Study acronym | ABC-07 |
| Study objectives | 1. The overall aim of the feasibility component of the trial is to determine if it is feasible to deliver SBRT in a multi-centre trial setting in a rare disease 2. The overall aim of the phase II trial is to evaluate the efficacy of 8 cycles of CisGem chemotherapy compared to 6 of cycles of CisGem chemotherapy followed by SBRT |
| Ethics approval(s) |
Approved 04/08/2015, London - Hampstead Research Ethics Committee (2 Redman Place, Stratford, London, E20 1JQ, United Kingdom; +44 (0)20 7104 8284; hampstead.rec@hra.nhs.uk), ref: 15/LO/1077 |
| Health condition(s) or problem(s) studied | Biliary tract cancer |
| Intervention | Current interventions as of 19/07/2017: All patients will be registered to receive 6 cycles of chemotherapy consisting of cisplatin 25 mg/m2 plus gemcitabine 1000 mg/m2 on days 1 and 8 of a 21-day cycle. Treatment takes about 2 hours each time. Patients will then be randomised to one of two groups. Investigational arm: Participants receive 5 or 15 fractions of SBRT over 5-21 days approximately 6 weeks after the start of cycle 6. (Number of fractions and duration of treatment depends on size of tumour on end of cycle 4 imaging). Standard arm: Participants receive 2 further cycles of CisGem (8 cycles in total) All patients will be followed up every 3 months for up to 2 years from date of registration. Previous interventions: All patients will be registered to receive 6 cycles of chemotherapy consisting of cisplatin 25 mg/m2 plus gemcitabine 1000 mg/m2 on days 1 and 8 of a 21-day cycle. Treatment takes about 2 hours each time. Patients will then be randomised to one of two groups. Investigational arm: Participants receive 5 fractions of SBRT over 5-15 days approximately 6 weeks after the start of cycle 6. Standard arm: Participants 2 further cycles of CisGem (8 cycles in total) All patients will be followed up every 3 months for up to 2 years from date of registration. |

| Key inclusion criteria | Current inclusion criteria as of 19/07/2017: 1. A histopathological/cytological diagnosis of locally advanced, non-resectable biliary tract carcinoma (intra or extrahepatic), or ampullary carcinoma 2. Not suitable for radical surgery, or medically unfit for surgery as decided by a hepatobiliary MDT 3. Tumour visible on crosssectional imaging 4. Measurable disease (according to RECIST criteria v1.1) (If disease is not measurable using RECIST v1.1, due to location in the vicinity of the hilum, the tumour must be visible for targeting with radiation using other multimodality imaging such as ERCP, MRCP) 5. Tumour (and nodes if involved) must be ≤12 cm in the longest dimension. For patients with non-measurable disease, sites should use the CT reconstructions (coronal or sagittal views) to measure tumour size. 6. Adequate biliary drainage 7. WHO performance status (PS) 0 or 1 8. Adequate haematological function: 8.1. Haemoglobin ≥ 100 g/L (the use of transfusion to achieve desired Hb is acceptable) 8.2.

Adequate renal function: 10.1. Serum urea < 1.5 x ULN 10.2. Serum creatinine < 1.5 x ULN 10.3. GFR ≥ 45 mL/min using a validated creatinine clearance calculation (e.g. CockroftGault or Wright formula). If the calculated creatinine clearance is less than 45 mL/min, GFR should be assessed using an isotopic clearance method to confirm GFR ≥ 45 mL/min 11. Life expectancy of more than 12 weeks 12. Aged 16 years or over 13. Patients may have had prior chemotherapy as long as patient meets all other inclusion/exclusion criteria 14.

| Key exclusion criteria | Current exclusion criteria as of 19/07/2017: 1. Metastatic disease 2. Direct tumour extension in the duodenum, stomach, small bowel or large bowel. 3. Previous abdominal radiotherapy or previous selective internal radiotherapy such as hepatic arterial Yttrium therapy 4. Previous hypersensitivity to platinum salts 5. Any evidence of severe or uncontrolled systemic diseases which, in the view of the investigator, makes it undesirable for the patient to participate in the trial (including diabetes with established sensory peripheral neuropathy, unstable or uncompensated respiratory, cardiac, hepatic or renal disease) 6. History of prior malignancy that could interfere with the response evaluation or survival. (Exceptions include: insitu carcinoma of the cervix treated by conebiopsy/resection, nonmetastatic basal and/or squamous cell carcinomas of the skin, or any early stage malignancy radically treated in the last two years, early prostate cancer under surveillance. 7. Other concomitant anticancer therapy (except steroids) 8. Any psychiatric or other disorder likely to impact on informed consent. 9. Women who are pregnant or lactating 10. Whilst not specifically excluded, patients with significant hearing impairment must be made aware of potential ototoxicity and may choose not to be included. If included, it is recommended that audiograms be carried out at baseline and prior cycle 2 of CisGem. Previous exclusion criteria: 1. Metastatic disease 2. Direct tumour extension in the duodenum, stomach, small bowel or large bowel. 3. Previous abdominal radiotherapy or previous selective internal radiotherapy such as hepatic arterial Yttrium therapy 4. Previous hypersensitivity to platinum salts 5.

History of prior malignancy that could interfere with the response evaluation (exceptions include insitu carcinoma of the cervix treated by conebiopsy/resection, nonmetastatic basal and/or squamous cell carcinomas of the skin, or any early stage (stage I) malignancy adequately resected for cure greater than 5 years previously) 7. Other concomitant anticancer therapy (except steroids) 8. Any psychiatric or other disorder likely to impact on informed consent. 9. Women who are pregnant or lactating 10. Whilst not specifically excluded, patients with significant hearing impairment must be made aware of potential ototoxicity and may choose not to be included.
