Prevention of Frailty With Fisetin and Exercise in Breast Cancer Survivors
(PROFFi)
What this study is about
This phase II trial tests how well fisetin and exercise works in preventing frailty in breast cancer survivors. Fisetin is a natural substance found in strawberries and other foods and is available as a nutritional supplement. Nutritional supplements may be useful in eliminating cells that have undergone a process called senescence.
View original scientific description
This phase II trial tests how well fisetin and exercise works in preventing frailty in breast cancer survivors. Fisetin is a natural substance found in strawberries and other foods and is available as a nutritional supplement. Nutritional supplements may be useful in eliminating cells that have undergone a process called senescence. Senescence is when a cell ages and permanently stops dividing but does not die.

Primary outcome measures
Change in 6 minute walk distance (6MWD)
Time frame: From baseline to day 120
The 6MWD will assess the distance walked over 6 minutes and is measured in meters. A linear model will be fit to outcome variable (change score) with a factor variable representing the four study arms and control for baseline 6MWD, site, and age stratum. The analysis will be conducted as intention-to-treat analysis. Will conduct an as-treated analysis, comparing the treatments received (instead of as-randomized).
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Women who are postmenopausal at the start of study treatment
- Postmenopausal status will be established as follows: Women who are 50 years or older and who are not menstruating for greater than 12 months will be considered postmenopausal. Women who are less than 50 years with an intact uterus and ovaries must have chemically induced menopause (e.g., ovarian suppression) to be considered postmenopausal
- Women with a diagnosis of early-stage breast cancer (stage I, II, III) treated with neo/adjuvant chemotherapy within 12 months of starting study treatment
- No evidence of active/recurrent breast cancer or other serious chronic illnesses
- Have evidence of pre-frail health, defined as a 6-minute walk distance (400-480m) at baseline
- Platelets \> 60,000/mm\^3
- White blood cell count \> 2,000/mm\^3
- Absolute neutrophil count \> 500/mm\^3
- Hemoglobin ≥ 8.0 g/dL
- Total bilirubin ≤ 3.0 X upper limit of normal (ULN)
- Aspartate aminotransferase (AST) ≤ 4.0 x UL

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
