Brief Summary

Diarrhea is a relatively common complication in patients with cancer. At its inception, several mechanisms participated; malabsorption on the basis of mucositis induced by chemotherapy, dysbiosis induced by broad-spectrum antibiotics and predisposition to infectious diarrhea in immunocompromised patients. Some cytostatics and their metabolites can also induce diarrhea directly due to effect on the intestinal mucosa. Use of probiotics in prevention and treatment of diarrhea relies on both the theoretical assumptions and the results of several clinical trials. Lactic acid bacteria involved in the treatment of dysbiosis, compete for substrate with pathogenic bacteria, produce bacterio-cins, increase transepithelial resistance. Their enzymatic activity affects activation or deactivation of metabolites which cause diarrhea. Production of short chain fatty acids, which are important for the maintenance of intestinal mucosal cells also contributes to their antidiarrhoeal effect. This randomized, double-blind, placebo controlled, multicentre trial was designed to evaluate potential of probiotics to prevent grade 3-4 diarrhea in patients treated by irinotecan based chemotherapy during first 6 weeks of irinotecan based chemotherapy

Outcome Measures

Primary Outcomes (1)

  • Prevention of grade 3-4 diarrhea induced by irinotecan based chemotherapy

    To determine the efficacy (as measured by prevention of grade 3/4 diarrhea) of probiotic formula Probio-Tec® BG-VCap-6.5 given orally to patients with colorectal cancer starting new line of irinotecan based chemotherapy. Response will be defined as prevention of grade 3/4 diarrhea according to definition of NCI CTC version 4.0

    first 6 weeks of irinotecan based chemotherapy

Secondary Outcomes (4)

  • Progression-free survival

    1 year

  • Prevention of any grade of diarrhea

    6 weeks

  • Prevention of other gastrointestinal symptoms

    6 weeks

  • Incidence of treatment-emergent adverse events [Safety and Toxicity]

    6 weeks

Study Arms (2)

active probiotic formula

ACTIVE COMPARATOR

Intervention: Probiotic formula Probio-Tec® BG-VCap-6.5 will be administered at a dose of 3x1 cps per day orally for 6 weeks. No premedication or patient monitoring after administration of probiotic formula is required. Probiotic formula may be taken after meals or snacks to reduce stomach upset. Swallow the capsule or in case of problems with swallowing, capsule can be opened, content mixed with small amount of food. Food must not be hot. Patients should receive full supportive care during the study, including transfusion of blood and blood products, treatment with antibiotics, anti-emetics, anti-diarrheal agents, analgesics, erythropoetin, or bisphosphonates, when appropriate.

Drug: Probio-Tec® BG-VCap-6.5

placebo

PLACEBO COMPARATOR

Intervention: Maltodextrin will be used for placebo group and will be administered at a the same dose as active formula (3x1 cps per day orally for 6 weeks). Patients should receive full supportive care during the study, including transfusion of blood and blood products, treatment with antibiotics, anti-emetics, anti-diarrheal agents, analgesics, erythropoetin, or bisphosphonates, when appropriate.

Drug: Placebo

Interventions

Each capsule contents: 2 lyophilized probiotic strains, total amount of minimum 2,7x10 9 CFU/cps, ratio LGG®: BB-12® = 50% : 50% (Culture percentages are based on cell concentration and are approximate) Lactobacillus rhamnosus GG® (ATCC 53103) Bifidobacterium animalis subsp. lactis BB-12® (DSM 15954) Additives: maltodextrin, microcrystalline cellulose, silicium dioxide, magnesium stearate
