E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To assess the efficacy of eight weeks treatment with 2 x 1 mg/day or 2 x 2 mg/day budesonide orodispersible tablets vs. placebo for prevention of oesophageal strictures after endoscopic submucosal dissection. |
• Beoordeling van de werkzaamheid van een acht weken durende behandeling met 2 x 1 mg/dag of 2 x 2 mg/dag budesonide orodispergeerbare tabletten vs. placebo ter preventie van oesofagusstricturen na endoscopische submucosale dissectie. |
|
E.2.2 | Secondary objectives of the trial |
• To study safety and tolerability of budesonide orodispersible tablets vs. placebo by means of adverse events and laboratory parameters. • To assess patients’ quality of life.
|
• Onderzoek naar de veiligheid en verdraagbaarheid van budesonide orodispergeerbare tabletten vs. placebo aan de hand van ongewenste voorvallen en laboratoriumparameters. • Beoordeling van de kwaliteit van leven van de patiënten.

E.3 | Principal inclusion criteria |
• Signed informed consent, • Male or female patients, 18 to 80 years of age, • Estimated life expectancy of at least three years, • ECOG Performance Status of ≤ 2 at the randomisation visit (i.e. after the ESD-procedure), • Biopsy proven or endoscopically suspect oesophageal SCC and/or high grade dysplasia in a focal lesion of the squamous epithelium, treated with ESD, • Mucosal defect ≥ 75% oesophageal circumference after ESD, or patient with a complete circumferential ESD, • Negative pregnancy test in females of childbearing potential at the screening visit.

|
E.4 | Principal exclusion criteria |
• Any prior or intended chemotherapy for oesophageal cancer, • Any prior ESD in the area where ESD will be done, • Any prior or intended oesophageal surgery or surgery for the mediastinum, endoscopic mucosal resection (EMR), or radio frequency ablation (RFA), in the area where ESD will be done, • Evidence of regional lymph node metastases or distant metastases prior to ESD, • Any prior or intended radiotherapy which involves or affects the area of ESD, • Any prior endoscopic dilation for oesophageal stenosis, • Any other concomitant oesophageal disease, • Any severe concomitant disease, which in the opinion of the investigator might have an influence on the patient’s compliance or the interpretation of the results, or any disorder which in the opinion of the investigator might affect the patient’s safety, • Any systemic therapy for any reason that may affect assessment of primary or secondary endpoints.
