Mesenchymal Stem Cells for Age-Related Frailty

• Status: Not yet recruiting
• Trial end date: 2025-07-31
• Target enrollment: 0
• Participant gender: All

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.

• Severe neuromuscular disease (e.g., multiple sclerosis, Parkinson's disease, Amyotrophic lateral sclerosis)

• Renal impairment as defined by an estimated glomerular filtration rate (eGFR or less than 30 ml/min/1.73 m2)

• Have any clinically important screening laboratory values, including hemoglobin <10.0 g/dL, WBC <2.500/ul or platelet count<100,000/ul, AST or ALT > 3 times the upper limit of normal, INR>1.3 not due to reversible cause (e.g., warfarin)

• Treatment with another investigational drug or other intervention within three months

• A history or current evidence of any condition, laboratory abnormality, or other circumstance that might confound the interpretation of the results
