in a first degree family member (father/mother/brother/sister/son/daughter)
• Allergy or intolerance to salicylates
• Patients with local or distant recurrent disease
• Previous malignancies other than CIN or SCC with a disease free survival less than 5 years
• Presence of 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 |
|
E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is 5 year Overall Survival (5y-OS).
The time to an event for OS is defined as the time interval between the date of randomisation and
the date of death. A patient that is still alive at the last date of follow-up patient is censored for
analysis and the time at risk corresponds to the time interval between the date of randomisation
and the date of last follow up. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
• Disease Free Survival (DFS). The time to an event for DFS is defined as the time interval between the
date of randomisation and the date of disease recurrence or death, whichever comes first. The date of
radiological evidence, e.g. CT, MRI, etc, or colonoscopy will be considered as date of recurrence.
• Time to Treatment Failure (TTF). The time elapsed between randomisation until treatment
discontinuation due to disease progression, unacceptable toxicity, death or any other event of interest. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Whenever disease recurs, disease progresses, toxicity issues arise or the patient dies. |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
The study will be terminated when there is one of the following criteria:
-Serious adverse side effects related only to acetylsalicylic acid use in >5 % of the
subjects
-If the results of the interim analysis do not show survival benefit for
acetylsalicylic acid use or if these results show a survival gain for
control group.
OR LVLS |
De studie zal vroegtijdig beëindigd worden op basis van de volgende criteria:
- Ernstige bijwerkingen gerelateerd aan acetylsalicylzuur gebruik bij meer dan 5% van
de proefpersonen
- Als de resultaten van de interim analyse geen betere overleving geven
voor de acetylsalicylzuur gebruikers of als de resultaten een betere
overleving laten zien voor de controle groep
Of: laatste bezoek van de laatste proefpersoon. |
