Official title
Impact of Probiotic Supplementation on Neuropathy Induced by Adjuvant Chemotherapy in Patients With Colon Cancer: a Phase III Randomized Study
Overview
The pbjective of this study is to assess the impact of a multi-strain bacteria probiotic OXXYSLAB® on the reduction of oxaliplatin-induced peripheral neuropathy in patients with stage III colon cancer receiving FOLFOX or XELOX regimen in adjuvant treatment, assessed using the oxaliplatin-specific scale of Levi.
Detailed description
Patients are randomized (1:1 ratio), between:
* Experimental group: Multi-strain PROBIOTIC treatment (OXXYSLAB®) 1.5 g sachet containing maltose and the OXXYSLAB® multi-strain probiotic formulation (eight different live bacterial strains, 200 billion bacteria). * Control group: PLACEBO treatment 1.5 g sachet strictly identical to OXXYSLAB®, containing maltose only.
Interventions
- Dietary supplement PROBIOTIC SUPPLEMENTATION BY OXXYSLAB®
PROBIOTIC treatment (OXXYSLAB®) starts 1 week before first administration of chemotherapy (XELOX or FOLFOX) and be continued until 1 week after end of the last cycle of chemotherapy. PROBIOTIC treatment (OXXYSLAB®) is administered orally , in 1 daily dose. - Dietary supplement PLACEBO supplementation
PLACEBO supplementation starts 1 week before first administration of chemotherapy (XELOX or FOLFOX) and be continued until 1 week after end of the last cycle of chemotherapy. PROBIOTIC treatment (OXXYSLAB®) is administered orally , in 1 daily dose.
Primary outcome measures
- Proportion of patients who experience a grade ≥2 peripheral neuropathy [Time frame: Around week 12 (+/- 7 days) after initiation of treatment]
