Efficacy and Safety of HEP-40 Chitosan for Mild to Moderately Elevated Cholesterol
Chitosan is a natural product that is produced commercially through the deacetylation of chitin, which is found in the exoskeleton of crustaceans. It has been suggested that chitosan has a lipid-lowering effect.
This study was designed to determine if HEP-40 chitosan (Enzymatic Polychitosamine Hydrolysate - 40kDa), a short-chained chitosan with a molecular weight of 40 kDa, is safe and effective in lowering LDL-cholesterol levels in patients with mild to moderately elevated cholesterol levels and who have not been previously treated with other lipid-lowering agents.
Chitosan is a natural product that is produced commercially through the deacetylation of chitin, which is found in the exoskeleton of crustaceans. It has been suggested that chitosan has a lipid-lowering effect by binding to fatty acids and cholesterol in the gastrointestinal tract and restricting their absorption.
This study was designed to determine if HEP-40 chitosan (Enzymatic Polychitosamine Hydrolysate - 40kDa), a short-chained chitosan with a molecular weight of 40 kDa, is safe and effective in lowering LDL-cholesterol levels in patients who have not been previously treated with lipid-lowering agents and who have cholesterol levels that are mild to moderately above the levels recommended by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines.
This is a multi-centre, randomized, double-blind, placebo-controlled study. Following a 4-week Pre-Randomization Phase where patients will be instructed to maintain a stable diet, patients will be randomized to one of the following study groups for a 12-week Active Treatment Phase:
- HEP-40 400 mg three times a day (400 mg TID)
- HEP-40 800 mg twice a day (800 mg BID)
- HEP-40 800 mg three times a day (800 mg TID)
- HEP-40 2400 mg once a day (2400 mg QD)
- Placebo, three times a day (placebo)
The primary objective is to evaluate the clinical benefit of administering HEP-40 chitosan at different doses and at different dosing regimens compared with placebo. Clinical benefit will be defined as the reduction in LDL-cholesterol after 4 weeks of active treatment.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Medical and Biotech [MESH] Definitions
A linear polysaccharide of beta-1->4 linked units of ACETYLGLUCOSAMINE. It is the second most abundant biopolymer on earth, found especially in INSECTS and FUNGI. When deacetylated it is called CHITOSAN.
Deacetylated CHITIN, a linear polysaccharide of deacetylated beta-1,4-D-glucosamine. It is used in HYDROGEL and to treat WOUNDS.
A condition with abnormally high levels of CHOLESTEROL in the blood. It is defined as a cholesterol value exceeding the 95th percentile for the population.
An oily liquid extracted from the seeds of the safflower, Carthamus tinctorius. It is used as a dietary supplement in the management of HYPERCHOLESTEROLEMIA. It is used also in cooking, as a salad oil, and as a vehicle for medicines, paints, varnishes, etc. (Dorland, 28th ed & Random House Unabridged Dictionary, 2d ed)
High molecular weight polysaccharides present in the cell walls of all plants. Pectins cement cell walls together. They are used as emulsifiers and stabilizers in the food industry. They have been tried for a variety of therapeutic uses including as antidiarrheals, where they are now generally considered ineffective, and in the treatment of hypercholesterolemia.
The "dry eye syndrome" DES is a highly prevalent ocular disease, in particular in the elderly population. One mainstay of therapy for patients suffering from DES is the use of topically ad...
Purpose: This study is aimed to be a prospective clinical trial to investigate the efficacy of a chitosan-coated nasal packing (ChitoFlex® used in conjunction with the HemCon Nasal Plug)...
The purpose of this study is to determine if the use of HemCon chitosan-based dressings is effective to facilitate safe, effective debridement of chronic wounds in the operating room and i...
The primary objectives of this study are to evaluate the safety of MD-0727 in patients with primary hypercholesterolemia and to determine the low density lipoprotein cholesterol (LDL-C) lo...
The purpose of this study is to evaluate the lipid lowering effects of an investigational drug in patients with hypercholesterolemia (high cholesterol).
In this study, a cell-penetrating peptide, the transactivating transcriptional factor (TAT) domain from HIV, was linked to a chitosan/doxorubicin (chitosan/DOX) conjugate to form a chitosan/DOX/TAT hy...
Hepatocellular carcinoma (HCC) is frequently associated with paraneoplastic hypercholesterolemia. However, cholesterol overproduction in HCC tissue has never been demonstrated. An aim of this study is...
Pure chitosan nanogels were produced, used to adsorb copper(II), and their antimicrobial activities were assessed. The complexation of copper(II) with chitosan solutions and dispersions was studied us...
This study investigated the antimicrobial effect of a chitosan coating+allyl isothiocyanate (AIT) and nisin against Salmonella on whole fresh cantaloupes. Cantaloupes were inoculated with a cocktail o...
The adsorption behavior and mechanism of chitosan in aqueous LiOH solution was studied systemically. The results showed that the adsorption of chitosan was mainly due to the breakage of its hydrogen b...
