E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To assess the Disease Control rate after 4 months of treatment for each patient (complete response + partial response + stable disease) rate
|
|

• Progression Free Survival • Overall Survival • Time to tumour progression • Objective response rate • Tolerability/ toxicity • Biomarkers of response/resistance to therapy

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Translational biomarker research sub-study:
If consented to, in a separate sub-study research consent: - archived tissue (paraffin embedded tissue blocks) and fresh frozen tissues will be collected, where possible, for analysis of molecular determinants of response to treatment. - upper gastrointestinal tract endoscopy will be performed within 28 days prior to study dose. Other specimens will be taken at 1 month, and at time of tumour progression where possible. - 2x10ml blood samples (one plasma and one serum) will be taken at 28 days prior to study dose, at 1 month (before cycle 2 treatment), and at time of tumour progression where possible. Serum, plasma and white cells will be stored at site for later shipment for biomarker research analysis. Contact in St James’s Hospital is study Chief Investigator Dr Ken O’Byrne (see contacts list in appendix G of protocol).
Objectives: For predictive and drug effect markers, comparison of pre- and post-drug values will be performed. The transcriptone and proteomic data in those patients whose disease is controlled with therapy at 4 months will be compared to the transcriptone and proteomic data in those whose tumours progress. Through this work, a number of genes and or proteins may emerge as potential biomarkers predictive of sensitivity or resistance to sorafenib therapy. The epigenomic/genomic and proteomic data will be analysed by Dr Alan Kelly, Chartered Statistician, Senior Lecturer in Biostatistics, Trinity College. |

Men should use adequate birth control for at least three months after the last administration of sorafenib. • Ability to understand and the willingness to sign a written informed consent, given according to ICH/GCP, and national/local regulations. A signed informed consent must be obtained prior to any study specific procedures.

The patient must not be undergoing acute steroid therapy or taper (chronic steroid therapy is acceptable provided that the dose is stable for one month prior to and following screening radiographic studies). • Previous treatment with a tyrosine kinase inhibitor or anti-angiogenic agent (licensed or investigational) such as sunitinib or bevacizumab. • Any previous drug treatment (licensed or investigational) that targets the RAS, VEGF, VEGFR or EGFR pathway. • Investigational drug therapy during or within 30 days. • Concomitant treatment with rifampin or St. John's Wort. • Any cancer chemotherapy, immunotherapy, radiotherapy or hormonal treatment over the previous 4 weeks. Palliative radiotherapy to symptomatic disease sites is permitted. • Concurrent anti-cancer chemotherapy, immunotherapy or hormonal therapy except bisphosphonates. • Women who are pregnant, nursing, or planning pregnancy within 6 months after the last treatment (this includes men who plan to father a child within 6 months of the last treatment). • Therapeutic anticoagulation with vitamin K antagonists such as warfarin, or with heparins or heparinoids. Low dose warfarin (1 mg p.o. qd) is permitted if the INR is < 1.5. Low-dose aspirin is permitted. • Known or suspected allergy to sorafenib or any agent given in the course of this trial. • Previous cancer that is distinct in primary site or histology from oesophago-gastric junction cancer excluding cervical cancer in-situ, treated basal cell carcinoma, superficial bladder tumours [Ta and Tis] or any cancer curatively treated > 3 years prior to study entry. • Concurrent cancer that is distinct in primary site or histology from oesophago-gastric cancer. • Substance abuse, medical, psychological or social conditions that may interfere with the patient’s participation in the study or evaluation of the study results. • Any condition that impairs patient’s ability to swallow whole pills. • Any malabsorption condition. • Patients with seizure disorder requiring medication (such as steroids or anti-epileptics). • History of organ allograft. • Patients undergoing renal dialysis. • Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial.
