Clinical Trial Summary

A randomized, double-blind placebo-controlled trial to study the effects of chicken extract and collagen on join, bone and muscle functions in comparison to an active comparator glucosamine

Description:

Osteoarthritis (OA) of the knee, which entails the destruction of knee cartilage and remodeling of the adjacent bone, is one of the leading causes of disability among elderly adults. Consequences of severe knee OA, including loss of mobility and limited daily activities, affect individuals and society economically. The World Health Organization (WHO) Global Burden of Disease Study, conducted in 21 epidemiological regions worldwide, reported a 26.6% increase in the burden of knee OA from 1990 to 2010.

Current therapies for OA include various over the counter analgesics, a number of non-steroidal anti-inflammatory drugs (NSAIDs), intra-articular injections of corticosteroids or hyaluronic acid, plus tramadol and other opioid analgesics to relieve severe pain. , While these therapies can alleviate symptoms in the near term, their ultimate impact on the pathophysiologic progression of OA is limited. In addition, there are considerable side effects associated with the use of these drugs. Total joint replacement is typically the final and only effective solution for relieving pain and disability.

As a result, OA sufferers always turn to natural nutraceuticals to ease their pain and discomfort. These products are commonly used because they are well tolerated and considered safe. Nutraceuticals are defined as functional foods, natural products, or parts of food that provide medicinal, therapeutic, or health benefits, including the prevention or treatment of disease. Currently, glucosamine and chondroitin are the two most commonly used nutraceuticals in humans to alleviate pain associated with arthritis. However, recent randomized controlled trials and meta-analysis of these supplements have shown only small-to-moderate symptomatic efficacy in OA.

It therefore seems appropriate to explore other natural supplements/ingredients. There is growing interest in hydrolyzed collagen (or collagen hydrolysate [CH]) as a nutraceutical supplement because collagen-derived peptides harbor a variety of interesting biological properties. CH has been found to down-regulate inflammatory markers involved in joint inflammation and cartilage degradation such as interleukins (ILs), IL-6, IL-7, IL-9 and IL-12 as well as monocyte-chemoattractant-1 (MCP-1) in chondrocytes induced with IL-1 beta. In addition, CH reduces bone resorption in an in vitro model for regulation of osteoclastic differentiation and bone resorption by RANKL system (unpublished data).

CH has received considerable attention in relieving OA-associated symptoms. The hypothesis of how CH may reduce OA-associated symptoms includes providing bioavailable substrate (building blocks) for the collagen fibrillar network, which provides tensile strength for the matrix of articular cartilage. Oesser et al. in a series of preclinical studies, demonstrated that CH passes across the mucosal barrier in the small bowel as a complete peptide that is no longer subject to enzymatic cleavage, accumulates in cartilage tissue, and stimulates production of type II collagen (the major protein in articular cartilage) and proteoglycans in the extracellular matrix of cartilage. , , In addition to these preclinical studies, open label, comparative, and prospective, randomized, placebo-controlled clinical trials and experimental findings have been published, with several studies providing evidence of a beneficial effect on measurements of joint health from the administration of collagen hydrolysate in a variety of patient populations, mostly OA patients. , , , , , CH per day for 3 months produced an improvement in joint health or function, such as reduction in pain,11,12,14 decreased dependency on pain medications,14 and improvement in leg strength.16 Given these observations, the investigators develop a supplementation of chicken essence with additive of CH—Brands Essence of Chicken plus CH (BEC-CH). The CH is derived from chicken cartilage. It is a soluble naturally occurring matrix of hydrolyzed collagen type II, chondroitin sulfate, and hyaluronic acid. The composition is similar to that of the human articular cartilage lining found in the synovial joints. Regarding BEC, it has been consumed for decades as a health tonic for energy boosting and fatigue recovery. In fact, BEC supplementation has been clinically proven to accelerate the recovery from exercise by increasing the rate of clearance of plasma lactate and ammonia and hence reduces muscle fatigue. However, all of these data are based on supplementation of either BEC of CH per se in clinical or in in vitro settings. Thus, it is crucial to investigate the efficacy of both BEC and CH when taken in combination on joint, bone, and muscle function. To answer these questions and to investigate its tolerability and efficacy, this randomized, double-blind, four-arm pilot study is thus carried out. It is hypothesized that supplementation with BEC-CH might relieve joint discomfort, restore joint function, and also be beneficial to bone and muscle.
