NCT02467582

Brief Summary

Following complete resection of their primary tumor, potentially eligible stage II or stage III colon cancer patients will undergo central PIK3CA testing. Patients with somatic mutations will be 2:1 randomized to daily aspirin 100 mg versus placebo for a a maximum of 3 years or until disease recurrence, patient death or withdrawal of consent, whichever occurs first. Patients will be followed up for at least 3 years from the date of surgery. The intake of aspirin or placebo is independent of adjuvant chemotherapy, and does not impact on the indication to give (or not to give) adjuvant chemotherapy.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically confirmed diagnosis of adenocarcinoma of the colon.
  • Stage II (pT3/T4 N0 cM0) or stage III (pTx pN+ cM0) colon cancer.
  • Availability of cancer tissue for central molecular testing.
  • Presence of predefined, activating PIK3CA mutation in exons 9 or 20 (centrally assessed).
  • Complete resection of the primary tumor (R0) within 14 weeks maximum before registration.
  • WHO performance status 0-2.
  • Age between 18-80 years.
  • Adequate hematological values: hemoglobin ≥ 80 g/L, platelets ≥ 50 x 109/L.
  • Adequate hepatic function: total bilirubin ≤1.5xULN, AST ≤2.5xULN, ALT ≤2.5xULN, AP ≤2.5xULN.
  • Calculated creatinine clearance \> 30 mL/min, according to the formula of Cockcroft-Gault.

You may not qualify if:

  • Previous or concomitant malignancy within 3 years of registration, except for adequately treated cervical carcinoma in situ or localized non-melanoma skin cancer.
  • Multiple adenocarcinomas of the colon.
  • Rectal cancer (defined as distance from anal verge to proximal/oral tumor edge ≤15 cm).
  • Severe or uncontrolled cardiovascular disease (congestive heart failure NYHA III or IV, unstable angina pectoris, history of myocardial infarction) within three months prior to registration.
  • Systemic rheumatic diseases or degenerative disorders affecting the musculoskeletal system with a relevant risk of requiring treatment with NSAIDs in the future.
  • Comorbidities that require regular (i.e. more than 3x per month, any dose) intake of acetylsalicylic acid or other NSAIDs or COX-2 inhibitors.
  • Clinically relevant upper gastro-intestinal bleeding within 12 months prior to registration.
  • Presence of any bleeding disorder that is an absolute contraindication to the use of aspirin.
  • General tendency to hypersensitivity and history of asthma triggered by salicylates or substances with a similar mechanism of action, and non-steroidal anti-inflammatory drugs in particular
  • Any serious underlying medical condition, at the judgment of the investigator, which could impair the ability of the patient to participate in the trial (e.g. uncontrolled infection, active autoimmune disease, uncontrolled diabetes).
  • Concurrent treatment with other experimental drugs or treatment in an interventional clinical trial within 30 days prior to trial entry. Concomitant use of adjuvant chemotherapy for stage III and high risk stage II colon cancer according to international treatment guidelines is allowed (chemotherapy regimens include intravenous 5-fluorouracil or oral capecitabine either alone or in combination with intravenous oxaliplatin).
  • Psychiatric disorder precluding understanding of trial information, giving informed consent or interfering with compliance for oral drug intake.
  • Any familial, sociological or geographical condition potentially hampering proper staging and compliance with the trial protocol.
  • Known or suspected hypersensitivity to any component of the trial drug or any agent given in association with this trial.
  • Known galactose-1-phosphate uridyl transferase deficiency, UDP galactose 4 epimerase deficiency, galactokinase deficiency, orFanconi-Bickel syndrome, congenital lactase deficiency,or glucose-galactose malabsorption (due to the lactose-containing placebo).
