E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Possibly, outcomes of treatment can be further improved by adding atezolizumab to neoadjuvant chemoradiation. As a first step we aim to know whether the addition of atezolizumab feasible. That is, we want to know how the treatment is tolerated and whether the treatment can be given as scheduled. |
Mogelijk kunnen de uitkomsten van de behandeling verder verbeterd worden door voorafgaand aan de operatie een nieuw middel – atezolizumab - aan de behandeling toe te voegen. Als eerste stap in het onderzoek hiernaar willen we weten of de toevoeging van atezolizumab aan de behandeling haalbaar is. Dat wil zeggen: we willen weten hoe de behandeling wordt verdragen en of de behandeling volgens planning kan worden gegeven. |

E.2.2 | Secondary objectives of the trial |
Secondary endpoints are:
• Incidence and severity of toxicity defined according to CTCAE v4.03 and Radiation Oncology Group (RTOG) criteria.
• Percentage completion of chemotherapy and radiation treatment
• Percentage withdrawal rate from surgery
• Incidence and severity of post-operative complications according to the Dindo classification.
• Pathological response according to the Mandard criteria.
• R0 resection rate.
• Progression free survival
• Overall survival
Exploratory endpoints are:
• Potential biomarker development based on assessment of tumour biopsies, faeces and blood samples and the proposed mechanism of action of study drugs. |
Secundaire eindpunten zijn:
• De incidentie en ernst van de toxiciteit gedefinieerd volgens CTCAE v4.03 en Radiation Oncology Group (RTOG) criteria.
• Percentage voltooiing van chemotherapie en bestraling
• Percentage terugtrekking een operatie
• De incidentie en ernst van postoperatieve complicaties volgens de Dindo classificatie.
• Pathologische reactie volgens de Mandard criteria.
• Percentage R0 resectie.
• Progressievrije overleving
• Algemene overleving
Verkennende eindpunten zijn:
• Potentiële biomarker ontwikkeling op basis van de beoordeling van de tumor biopten, uitwerpselen en bloedmonsters en het voorgestelde werkingsmechanisme van de studie medicijnen

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is feasibility defined as percentage completion of treatment with atezolizumab. Patients that do not complete treatment with atezolizumab for reasons other than toxicity will be replaced and not included in the analysis of the primary end point |
Het primaire eindpunt is haalbaarheid gedefinieerd als percentage voltooiing van de behandeling met atezolizumab. Patiënten die de behandeling met atezolizumab niet afmaken voor andere redenen dan toxiciteit, worden vervangen en niet opgenomen in de analyse van het primaire eindpunt. |
