Tumor with somatic alterations in PIK3CA, PIK3R1 or PTEN
- Colon or rectal cancer tumor stage II-III
- Patient between18-80 years (including)
- Radical surgery according to surgeon and pathologist
- Karnofsky performance status =70%
- Platelets = 100 x 109 / L
- Clean Colonoscopy or Computed Tomography (CT) colon within 3

Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 240
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 360
Hereditary colorectal cancer linked to familial colonic polyposis or
Lynch syndrome
- Inflammatory bowel disease (Crohn's disease or ulcerative colitis)
- Distant metastases
- Other cancers (excluding colorectal cancer or other skin cancer than
melanoma) within 3 years from screening
- Known bleeding diathesis (such as hemophilia)
- Concomitant antiplatelet therapy (eg clopidrogrel or ticlopidine) or
anticoagulant therapy (warfarin or low molecular weight heparin).
Postoperative
treatment with low molecular weight heparin must be
withdrawn before administration of study treatment
- Active gastritis or peptic ulcer, or significant surgical post-op bleeding,
within the previous three months assessed at screening and
randomization
- Ongoing regular use of corticosteroids, Nonsteroidal Anti-Inflammatory
Drug (NSAID)
- Uncontrolled hypertension according to Investigator's judgment
- Clinically significant liver impairment according to Investigators
judgment
- Existing renal failure according to Investigator's judgment. Renal
failure with decreased creatinine clearance <60 should lead to
consultation with a nephrologist.
- Significant medical illness that would interfere with study participation
- Pregnancy or breastfeeding females
- Known allergy to NSAIDs or ASA
- Current participation in another clinical trial that will be in conflict with
the present study
- Patients who are unlikely to comply with the protocol (e.g.
uncooperative attitude, inability to return for subsequent visits) and/or
otherwise considered by the Investigator to be unlikely to complete the
study
Patients with regular administration of ASA, defined as >3 doses/week,
will be included in the observation group. Other additional regular use of
ASA must be withdrawn before randomization.
