Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Group 1: TCF Regimen
Docetaxel (T): 30 mg/m2 Calculated to the nearest mg and administered as an intravenous (IV) infusion on day 1 and day 8 of each cycle
Cisplatin (C):60 mg/m2 administered as an intravenous (IV) infusion on day 1 of each cycle.
Peripheral Venous Infusion (PVI) 5 - Fluorouracil (5FU) : 160 mg/m2 daily, by continuous infusion administered via an indwelling venous line [Peripherally Inserted Central Catheter (PICC)] line or infusaport according to local practice)
Or
Capecitabine: 500 mg/m2 Oral twice daily for 21 days (42 doses)

Group 2: TCF regimen (as above) + Panitumumab
Pantiumumab: Administered intravenously (IV) by an infusion pump through a peripheral line or indwelling catheter 9mg/kg on day 1

Treatment described above will continue for a maximum total of 8 cycles ([1 cycle=3 weeks] x 8 cycles) which equates to 24 weeks.

Treatment: Drugs
Comparator / control treatment
Group 1: TCF Regimen (weekly docetaxel, cisplatin, fluoropyrimidine) without panitumumab.
Control group
Active

Outcomes
Primary outcome [1] 5316 0
To evaluate the response rates of wTCF given with or without panitumumab in the treatment of patients with metastatic or locally recurrent oesophago-gastric cancer.
Timepoint [1] 5316 0
Treatment will continue for 24 weeks and tumour response will be assessed according to Response Evaluation Criteria in Solid Tumours (RECIST v1.1) guidelines. Assessments will be carried out every 6 weeks during treatment and 12 weekly thereafter until disease progression, and then according to best-practice until death.
Secondary outcome [1] 9149 0
Overall survival
Timepoint [1] 9149 0
Overall survival will be measured from the date of patient entry to the date of death from any cause. Following completion of study treatment, patients will be followed up every 12 weeks until death.
Secondary outcome [2] 9150 0
Progression-free survival
Timepoint [2] 9150 0
Progression-free survival is measured from the date of patient randomisation to the study date of first evidence of disease progression or patient death. Disease progression will be defined by the RECIST v1.1 criteria every 6 weeks on study and 12 weekly from the end of study treatment (in follow up) until progression.
Secondary outcome [3] 9151 0
Treatment related toxicity
Timepoint [3] 9151 0
Toxicities will be recorded as adverse events on the Adverse Event case report form and must be graded using the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE) version 3.0, with the exception of skin- or nail-related toxicities, which must be graded using CTAE version 3.0 with modifications (Appendix 7 in study protocol). Adverse events will be assessed at baseline and at every cycle (every 3 weeks). A safety visit will be performed at 4 weeks +/- 7 days after the last study drug administration. In addition, every effort should be made to obtain blood for urea and electrolyte measurement, 8 weeks +/- 3 days after the last study drug administration.
Secondary outcome [4] 9152 0
Disease associated symptoms
Timepoint [4] 9152 0
Disease associated symptoms will be dervived from Quality of Life (QoL) questionnaires which will be completed 3 weekly for the first 12 weeks, then 6 weekly for the next 12 weeks, then 12 weekly until disease progression.
Secondary outcome [5] 9153 0
Quality of life during treatment.
Timepoint [5] 9153 0
Quality of life will be rated by EORTC QLQ-C30 together with the oesophageal specific module (OES18) or the gastric module (STO22) according to their primary tumour site. Patients with tumours involving the OGJ will complete the oesophageal module. Questionnaires will be completed 3 weekly for the first 12 weeks, then 6 weekly for the next 12 weeks, then 12 weekly until disease progression.

Eligibility
Key inclusion criteria
a) Age over 18.
b) Histological diagnosis of metastatic or locally recurrent oesophago-gastric cancer (squamous cell, adenocarcinoma or undifferentiated carcinoma)
c) Any primary oesophago-gastric site (oesophagus, oesophago-gastric junction (OGJ) or stomach)
d) Unidimensional measurable disease as assessed by computed tomography (CT) scan (RECIST v1.1 criteria). There must be at least one lesion > or equal to 20mm as measured by conventional computed tomography (CT) scan or > or equal to 10mm as measured by spiral computed tomography (CT) scan. All sites of disease must have been evaluated within 21 days of initiating study treatment and diagnosed by the investigator.
e) Prior palliative radiotherapy is allowed provided no concurrent chemotherapy was administered, all radiation toxicities have resolved to grade 1 or less and at least 14 days has elapsed from the last dose of radiotherapy until the start of chemotherapy in ATTAX 3. Furthermore, the site(s) of measurable disease must include at least one that is outside the radiation field unless this site has demonstrated clear progression, prior to randomisation.
f) World Health Organisation (WHO) performance status 0, 1 or 2 (Patients who ahave a performance status (PS) 2 should have serum albumin >30 g/L)

Adequate renal function (measured creatinine clearance>50ml/min) assessed by 24 hour urine or glomerular filtration rate (GFR) scan is also acceptable in cases where the Cockcroft-Gault method is considered inaccurate.
j) Adequate electrolytes, with serum magnesium level within the normal range and corrected serum calcium within the normal range.
k) Adequate hepatic function with serum total bilirubin <1.25 x upper limit of normal range and alanine aminotransferase (ALT)/aspartate aminotransferase (AST) <2.5x upper limit of normal range and alkaline phosphatase <5x upper limit of normal range

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be carried out by site staff via a web based randomisation system.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients will be randomised to receive one of the two treatment regimens using the method of minimisation, stratified by primary tumour site, histology (adenocarcinoma vs squamous), WHO performance status (0-1 vs 2) use of 5FU vs capecitabine and institution.
