Alleviation by Fisetin of Frailty, Inflammation, and Related Measures in Older Women

• Status: Recruiting
• Trial end date: 2022-06-30
• Target enrollment: 0
• Participant gender: Female

Summary

This is a pilot study to evaluate whether targeting inflammation will help reduce markers of insulin resistance inflammation, bone resorption and physical dysfunction in elderly women with gait disturbance. Positive results of this study would lead to the development of a larger clinical trial examining the effects of this intervention on age-related dysfunction.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Mayo Clinic
