Clinical Trial Summary

Frailty is a health state related to the aging process in which multiple body systems gradually lose their built-in reserves. It is a medical condition of reduced function in older adults which is associated with increased risks of adverse outcomes such as falls, disability, admission to hospital, or need for long-term care. Currently, there is no specific medical treatment of frailty. Mesenchymal stem cells (MSCs) are undifferentiated cells that self-replicated, and some may change into a particular cell type. These cells go to areas of injury due to signals released by injured cells. Upon reaching, the target tissue, MSCs repair injury by releasing growth factors and immune modulators to assist in the body's repair process. This initial study will assess the practicability of using MSCs for age-related frailty and provide information for planning a future full study of MSCs for maximizing Veteran's functional independence.

Description:

Frailty is an aging-related syndrome of impaired physiologic reserve and function across multiple organs, leading to increased vulnerability for adverse health outcomes. Frailty is associated with an increased risk for falls, disability, hospitalization, and mortality. Given the rapid growth in the aging population, the prevalence of frailty will continue to increase. In fact, Veterans receiving care at Veterans Health Administration are a high risk population for onset of frailty due to being predominantly older associated with a larger proportion of minorities, lower socioeconomic and educational status, higher prevalence of comorbidities, and higher rates of unemployment. Frailty now affects at least 3 of every 10 U.S. Veterans aged 65 years and older and is strongly associated with mortality. It is increasingly being recognized that frailty may be an appropriate target for intervention to reduce disability and dependence in older adults. However, there are no specific medical or biologic treatments that ameliorate or reverse frailty. Conversely, stem cell depletion is a key mechanism for age-related frailty. There is a strong link between frailty, inflammation, and the impaired ability to repair tissue injury due to decreases in endogenous stem cell production. Accordingly, a cell-based, regenerative treatment strategy i.e., allogenic bone-marrow derived mesenchymal stem cell (MSC) therapy may represent a novel therapy for aging frailty. MSCs migrate into the site of injury and home to the affected tissue, where they act to reduce inflammation and promote cellular repair. The advantages of MSCs as a therapeutic strategy for age-related frailty include availability, ease of isolation and expansion, multilineage differentiation and immunosuppression, free from ethical issues, and limited replicative lifespan. In this 6-month pilot study, the investigators will assess 1) the feasibility of MSC therapy in age-related frailty as it relates to functional improvement and 2) develop/refine MSC therapy as a new intervention in older Veterans with frailty, and thus provide preliminary participant response to inform a future trial.

Related Conditions & MeSH terms

• Frailty

Intervention

Drug:
• Mesenchymal Stem Cells (MSCs)
The MSCs are recovered from bone marrows of healthy donors. Each donor is carefully screened for pathogens to assure the product is safe. The MSCs are strictly compliant with FDA standards under Current Good Manufacturing Practice (cGMP) regulations.
