E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to test whether 5-ASA reduces occurence of colonic benign or malignant neoplasia compared to placebo in LS patients as detected by any colonoscopy until the end of study. |
|
E.2.2 | Secondary objectives of the trial |
To test wheter 5-ASA reduces the number of neoplasms (tumor multiplicity) and tumor progression to placebo in LS patients at the end of the study. Advanced adenomas are defined by a diameter above 1 cm villous or tubulu villous histology or high grade dysplasia.
- To investigate if differences between 5-ASA effects and placebo effects on the occurrence of colonic neoplasia, tumor multiplicity or tumor
progression depend on the history of colorectal cancer, sex and patients age (LS patients below 45 years of age or 45 years of age and older).
- To investigate differences between low and high dose 5-ASA with respect to the occurrence of colonic neoplasia, to tumor multiplicity and
tumor progression. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Proven tumor-free (including patients in which the polyps are removed endoscopically) carriers of a germline pathologic mutation on one of the MMR genes including MLH1, MSH2 (including EpCAM) and MSH6.
- Male or female subjects with the age > 30 years
- Signed written informed consent prior to inclusion in the study |
|
E.4 | Principal exclusion criteria |
- Presence of colonic endoscopically non-removable benign neoplasia (patient can be included if the adenoma is removed)
- Carriers of germline mutations in PMS 2.
- Patients with history of stage 3 and 4 cancer are excluded
- Presence of metastatic disease
- Regular use of Aspirin: daily use of ≥100mg in more than 3 continuous months within the last year
- Regular use of NSAIDs or COX-2 inhibitors: daily use in more than 3 continuous months within the last year
- Hypersensitivity to 5-ASA
- Patients after total or subtotal colectomy
- Colorectal surgery within the previous 6 months
- Unwillingness to participate or who is considered incompetent to give an informed consent
- Pregnant or breastfeeding women
- Participation in another clinical study investigating another IMP within 1 month prior to screening
- Renal insufficiency (GFR <30ml/min/1.73m2)
- Severe liver disease or liver failure (elevation of liver enzymes above 3xULN)
- Current or history of serious psychiatric disorder or alcohol/drug abuse that in the opinion of the investigator may impact the assessment of
safety, efficacy or protocol adherence
- Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study
participation or ability to comply with study procedures, investigational product administration and, in the judgment of the investigator, would
make the subject inappropriate for entry into this study. |

E.5 End points |
E.5.1 | Primary end point(s) |
Occurrence of neoplasms between groups is described by absolute frequencies and percentages with 95 % confidence intervals. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Active treatment period and follow up period. |
|
E.5.2 | Secondary end point(s) |
- The number of neoplasms per patient will be tested between groups by an analysis of variance, adjusting for country and history of cancer before randomization. In case of non-normally distributed residuals a suitable transformation to achieve normal distribution is considered.
- The tumor progress in the 4 ordered stages will be tested between groups by a chi-square trend test stratified for country and and history of cancer before randomization and modelled by an ordinal logistic regression.Tumor progression will be tested between groups by a chisquare trend test.
- Tumor occurrence in the right and left colon (location) will be described by absolute and relative frequencies The dependence of treatment effects on history of colorectal cancer, sex and patients age (<45 years and ≥45 years) will be assessed by modelling interactions between these factors and treatment in the corresponding regression models.
- Differences between high and low dose ASA for the occurrence of colonic neoplasia, tumor multiplicity and tumor progression will be analysed by the same methods as for the comparison between ASA and placebo.
- Occurrence and location of serrated benign or malignant neoplasms will be described by absolute and relative frequencies all tests are two-sided and a significance level of 5% is used. |
