 T-ChOSTM is a technical name for a food supplement product that is marketed in Iceland under the name BenectaTM. T-ChOS is manufactured using shellfish derived chitin as a raw material and is produced by Genis in Iceland. It is a blend of chitooligosaccharides that are hetero-complexes of N-acetyl-glucosamine and D-glucosamine. T-ChOS chitooligosaccharides have been specially selected to have high bioactivity in inflammatory models and strong binding affinity to YKL-40. Chitooligosaccharide induced blockade of YKL-40 signalling pathways may represents a promising approach. Pharmacokinetic profile of the T-ChOS in patients with advanced solid malignancies is not available.
