| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| Description of the 1-year overall survival after chemo-radiation therapy with or without panitumumab in irresectable carcinoma of the oesophagus. The control arm is used to validate whether the historical cohort used for comparison is similar to our success-rate |
|
| E.2.2 | Secondary objectives of the trial |
| Determination of toxicity, quantification of biological markers of response (pharmacodynamics of panitumumab), response monitoring by quantitative FDG positron emission tomography and quantification of circulating tumour and endothelial cells |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
| Patients (18-70 yrs) with histology proven untreated irresectable squamous cell carcinoma or adenocarcinoma of the oesophagus, with a Karnofsky performance status ≥70% without distant metastases. Patients should have no contra-indications for cytotoxic therapy or panitumumab or other serious (mental) illnesses or medical conditions. Patients may not have prior exposure to any EGFR pathway targeting agents, participate in another interventional study and should be able to give informed consent. |
|
| E.4 | Principal exclusion criteria |
| Patients with prior treatment for oesophageal cancer or with prior treatment with radiation therapy at the tumour or other site that will interfere with proposed treatment, who are pregnant or breast feeding, or planning to become pregnant within 6 months after the end of treatment or subjects (male or female) not willing to use highly effective methods of contraception (per institutional standard) during treatment and for 6 months after the end of treatment are excluded. Patients with a history of other prior malignancy in past 5 years, other than basal cell carcinoma, squamous cell carcinoma of the skin, or cervical carcinoma in situ are excluded as well. |
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
One-year OS for patients treated with each regimen. One year is defined as 365.242199 days. The survival is defined as the interval between randomisation and disease- or treatment-related death. Patients still alive after 18 months follow-up, lost to follow-up or death clearly not related to disease or treatment (e.g. accident)), are censored at the date of the most recent follow-up or at the analysis cut-off date, whichever comes first. Survival of the interventional arm (arm A) will be compared to the historical control group (section 4.4, p31) to determine whether it is of interest to pursue to a phase-III clinical trial. One-year OS of our control group (arm B) will only be compared to the historical control group to define whether our group has similar outcome as the historical controls. We consider the regimen used in arm A of interest for a (comparative) phase III trial if: -Arm A has a 1-year OS ≥77.5% and Arm B is not worse than the historic controls (i.e. 1-year OS≥40%). In other words the Odds Ratio of surviving 1 year must be larger than 2.30 -In case arm B has a 1-year OS significantly (i.e. 1-year OS<40%) less than the historical controls (which have a 1-year OS≈40%), the Odds Ratio of surviving 1 year must be larger than 2.30. E.g. in case the 1-year OS in arm B is 35% instead of the expected 60% we consider arm A of interest for a phase-III trial when the 1-year OS in this group is at least 55.3%
