E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
First primary objective: To determine the time point of induction of VEGF expression in the tumour tissue of oesophagus carcinomas during chemoradiation. Second primary objective: To determine whether the tumour promoting effects of this induction of VEGF expression can be inhibited by administration of bevacizumab. |
Het onderzoek heeft 2 hoofddoelen: 1) Het bepalen van het tijdpunt van inductie van vascular endothelial growth factor (VEGF) expressie in het tumor weefsel van oesofagus carcinoom, gedurende chemoradiatie. 2) Bepalen of het effect van VEGF of de tumorbloedvaten kan worden gestopt door de toevoeging van bevacizumab bij de behandeling. |

E.2.2 | Secondary objectives of the trial |
(1) Determination of mRNA expression levels of other pro-angiogenic factors than VEGF and factors that may influence radiosensitivity in the tumour tissue. (2) Determination of protein expression of pro-angiogenic factors and factors that may influence radiosensitivity in the tumour tissue with IHC. (3) Determination of Epstein Barr virus (EBV) status in the tumour tissue. (4) Quantification of vascular parameters in the tumour tissue to assess on-going angiogenesis. (5) Measurement of the plasma concentration of pro-angiogenic factors to determine if this correlates with the expression levels in the tumour tissue. (6) Determination of the expression level of angioregulatory miRNAs in the tumour tissue to assess whether this is affected during neoadjuvant chemoradiation. (7) Immune cell profiling by flow cytometric analysis (FACS) |
(1) bepalen van de mRNA expressie in de tumor van andere pro-angiogene factoren, en van factoren die de gevoeligheid van radiotherapie kunnen beinvloeden.

(3) Bepalen van Epstein Barr virus (EBV) status in het tumor weefsel. (4) Quantificeren van actieve angiogenese in het tumor weefsel, door middel van het bepalen van verschillen vasculaire uitkomstmaten. (5) Meten van plasma concentraties van verschillende pro-angiogene factoren, om te bepalen of dit correleert met de expressie niveaus in de tumor. (6) Bepalen van de expressie niveau van verschillende angioregulatoire micro RNA's (miRNA) in het tumor weefsel.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary parameter is the alteration of the VEGF expression on mRNA level in the tumour before and during the course of neoadjuvant chemoradiation. In addition, in the bevacizumab treated cohort, the primary parameter is the activity (phosphorylation) of the VEGF receptor (VEGFR) in the tumour tissue obtained with biopsy and the microvessel density of the resection material of the tumour. |
De primaire uitkomstmaat is de verandering van VEGF expressie op mRNA niveau in de tumor vooraf aan de behandeling vergeleken met de expressie gedurende de chemoradiatie. Tevens zal in het bevacizumab cohort de activiteit (phosphorylatie) van VEGF receptor in het tumor weefsel bepaald worden dat verkregen is bij het biopt, en de vaatdichtheid van de tumor in het weefsel dat bij resectie is weggehaald. |

1st timepoint: after study biopsy of the tumour during the chemoradiation treatment. 2nd timepoint: after the surgical resection of the residual tumour. |
1ste tijdpunt: na afname van de studie-biopt van de tumor tijdens de chemoradiatie. 2e tijdpunt: na de chirurgie resectie van het overgebleven tumourweefsel. |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
The trial will be terminated if no enhanced VEGF expression on mRNA level is found during the first 4 weeks of chemoradiation. If enhanced VEGF expression is found, the last cohort of patients will also receive bevacizumab during fractionated irradiation, to study the effect on angiogenesis in the tumour. After the bevacizumab cohort the study will be closed. |
De studie zal beeindigd worden als er geen verhoogde VEGF expressie op mRNA niveau wordt gevonden tijdens de eerste 4 weken van chemoradiatie. Als er wel een verhoogde expressie wordt geobserveerd, zal het laatste cohort van patienten ook bevacizumab bij hun bestaande therapie krijgen, gedurende de gefractioneerde radiotherapie. Hiermee zal het effect van bevacizumab op angiogenese in de tumour onderzocht worden. Na het bevacizumab cohort zal de studie gesloten worden. |
