Prove the hypothesis that dietary supplementation with bioflavonoids will diminish the recurrence rate of colonic neoplasia, we will implement a clinical trial comparing bioflavonoids and placebo in a double blind randomized clinical trial. To use a standardised supplementation of bioflavonoids, a commercially available preparation (Flavo-Natin®) will be used.

Condition Intervention Phase

Estimated Enrollment: 382
Study Start Date: May 2015
Estimated Study Completion Date: December 2016

Arms Assigned Interventions
Experimental: I
Flavonoid treatment
Dietary Supplement: Flavonoids
Nutritional Supplement: flavonoid mixture with 20 mg apigenin and 20 mg epigallocathechin gallate as tablets per day

Detailed Description:
The preparation contains a mixture of 200mg chamomile and tea (green tea) extract which contains naturally occurring bioflavonoids (2%) together with vitamins and folic acid. This flavonoids mixture will be applied for 3 years and the compliance and effects of this treatment will be determined by measuring the serum concentrations of apigenin and EGCG of the patients.

Exclusion Criteria:

  • subjects with any major relevant clinical abnormality (as based on extensive medical history, physi-cal examination, vital signs)
  • subjects with active cancer
  • subjects with any major clinically relevant laboratory abnormality.
  • subjects who participated in another trial with any investigational substance within the last 4 weeks
  • subjects who are known or suspected to be (social) drug dependent, incl. those drinking more than moderately and who are not willing to abstain from alcohol abuse during the active study phase
