11This is a single center phase 1 trial, which evaluates the pharmacokinetic profile of T-ChOS™ (food supplement Benecta™) in subjects with advanced solid tumors.
YKL-40 (also named chitinase 3 like-1 protein, CHI3L1), is a member of the mammalian chitinase like proteins and is a highly conserved glycoprotein. YKL-40 is produced by cancer cells and macrophages and promotes cancer progression by activating inflammation and inhibiting tumor angiogenesis. Thus, YKL-40 could be a new therapeutic target for patients with cancer.
T-ChOS™ is a technical name for a food supplement product that is marketed in Iceland under the name Benecta™. 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.
Safety and tolerability data will be collected to expand the safety/tolerability database for patients with advanced solid malignancies treated with oral T-ChOS. Patients will be allowed to receive T-ChOS on a continuous basis and therefore have the possibility to gain clinical benefit, if any. Safety and tolerability data collected after pharmacokinetic part of the study will be also added to the safety database for patients with advanced solid malignancies treated with oral T-ChOS.
T-ChOS 600 mg (two capsules, each 300 mg) daily in the morning 30 minutes before food.
The active substance used in the T-ChOS capsule formulation is a chitooligosaccharide blend.

For men and women of child-producing potential, the use of effective contraceptives methods during the study and at least 3 months after discontinuations of the investigational product is required. The following contraceptive methods are regarded as effective: intrauterine devices, hormonal contraceptives (contraceptive pills, implants, transdermal patches, hormonal vaginal devices or injections with prolonged release). Sterilised or infertile patients are exempt from the requirement to use contraception. In order to be considered sterilised or infertile, patients must generally have undergone surgical sterilisation (vasectomy/bilateral tubectomy, hysterectomy or bilateral ovariectomy) or be postmenopausal defined as 12 months or more with no menses prior to enrolment Not pregnant or nursing Be able to adhere to the study visit schedule and other protocol requirements EXCLUSION CRITERIA: Simultaneous participation in any other study involving investigational drugs or having participated in a study within 2 weeks prior to start of study treatment Current use of anticoagulation therapy such as heparins both unfractionated and low molecular weighted Symptomatic brain metastases Intake of any prohibited concomitant medication Prior and Concurrent Therapy at least 2 weeks prior to 1st dosing: Biologic/immunotherapy Chemotherapy Radiotherapy Major or laparoscopic surgery Other concurrent anticancer therapy Corticosteroids or other immunosuppressive medications. Inhaled or topical steroids are permitted.
