A Phase II Randomized Double-Blind Placebo-Controlled Study of Fisetin to Improve Physical Function in Breast Cancer Survivors
Jonsson Comprehensive Cancer Center
Summary
This phase II trial tests whether fisetin works to improve physical function in women who have received chemotherapy for stage I-III breast cancer treatment. Fisetin is a naturally occurring substance that is found in strawberries and other foods. Fisetin eliminates cells that have undergone a process called senescence. Senescence is when a cell ages and permanently stops dividing but does not die. Over time, large numbers of these cells build up in tissues throughout the body and can release harmful substances that causes inflammation and damages nearby healthy cells. Studies have shown that chemotherapy causes a build-up of these senescent cells. Giving fisetin may eliminate senescent cells and improve physical function in postmenopausal women who have received chemotherapy for breast cancer.
Description
PRIMARY OBJECTIVE: I. To determine the effect of fisetin on physical function, as assessed using the 6-minute walk distance (6MWD), in frail older breast cancer survivors. SECONDARY OBJECTIVES: I. To determine the effect of fisetin on other measures of physical function (grip strength, short physical performance battery \[SPPB\], frailty phenotype, physical function component of the 36 item short form survey \[SF-36\]). II. To determine the effect of fisetin on fatigability (Borg Rating of Perceived Exertion \[RPE\]). III. To determine the effect of fisetin on neuropathy (Quality of Life…
