  Purpose

Design: double blind controlled randomized trial with a parallel design and 3 treatment groups Description of subjects: Patients admitted in study centers for colorectal surgery under laporoscopy and/or laparotomy.

Product:

Product 1: BB536 and LA1 (10E9) Product 2: BB536 and LA1 (10E7) Placebo: Maltodextrin Number of patients: enrolled subjects: n=33, ITT data set: n=31, PP data set: n=30

Primary objective:

Colonization (biopsy+stools) of each bacteria for one of the dose at D0 (surgical procedure)

Secondary objectives:

  • Influence of the probiotic bacteria on the gut microflora
  • Modulation of the immune and inflammatory response

Additional objectives:

  • Investigate dose effect on La1 colonization
  • Investigate the effect of La1 colonization, treatment without La1 colonization, and absence of treatment and La1 colonization on other bacteria and on immunological parameters

Condition Intervention Phase
Colorectal Cancer Procedure: Probiotics (La1, BB536) Biological: probiotics (La1, BB536) Biological: placebo Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized Double-Blind Trial of Perioperative Administration of Probiotics in Colorectal Cancer Patients.
