简要总结

The purpose of this study is to determine the safety and efficacy of intraarticular injection of Cell-free Stem Cell-derived Extract Formulation for treatment of knee osteoarthritis symptoms.

详细描述

Osteoarthritis and other orthopaedic acute and degenerative conditions affect millions of people each year, resulting in significant pain and disability. Conservative modalities are limited, as they may not reverse the underlying pathology and may only provide minimal relief.

To address the limitations of traditional conservative modalities, there has been substantial interest in biologics for musculoskeletal regenerative medicine applications. The efficacy of these biologics is attributed to the presence of stem cells, growth factors (GFs), cytokines (CKs), and extracellular vesicles (EVs) including exosomes.

However, first generation biologics, specifically whole stem cell products, are not without their own inherent limitations, including establishing a reliable source with a stable phenotype, genetic instability and chromosomal aberrations, intravenous administration related toxicities caused by the physical trapping of the cells in the lung microvasculature, rejection by the host, formation of ectopic tissue, and tumorigenicity.

When considering how to harness the value of current biologics into a next generation product that can address existing limitations, it is important to consider current foundational knowledge regarding the mechanism of action of stem cell products. Recent literature regarding the beneficial effects of mesenchymal stem cells (MSCs) postulates that the mechanism of action is not due to their ability to grow and differentiate. Rather, it is secondary to their secretion of bioactive molecules such as growth factors, cytokines, and exosomes. GFs, secreted from stem cells, induce signal transduction pathways that initiate cell migration, proliferation, growth, and differentiation. CKs, similarly, can regulate inflammation, immune response, cellular differentiation, and tissue remodeling. Exosomes also are secreted by mesenchymal stem cells and act as a paracrine mediator to target cells, providing a regenerative microenvironment for damaged tissues.

As existing literature establishes that these aforementioned components of stem cells lead to regenerative responses, we have accordingly sought to establish if a sub-cellular approach to biologics can provide similar benefits while avoiding the risk profile, including immunogenicity, infection, and the potential for tumorgenicity, associated with whole stem cell products. In support of this hypothesis, recent studies have demonstrated that MSCs-derived exosomes can act as a cell-free therapeutic alternative to whole cell therapy with great regenerative potential. In addition, to the benefits by means of risk elimination, there may be further therapeutic benefits of a cellular derived therapeutic approach. For example, exosomes due to their smaller size, have the potential to migrate to target organs efficiently after, without getting trapped in the lung microvasculature. Additionally, a higher concentration of "active ingredients" can be administered directly to the patient, which may induce a larger healing response than is possible with whole stem cell therapies.
