Fisetin + Exercise for Breast Cancer
(PROFFi Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines whether fisetin, a natural supplement found in strawberries, combined with exercise, can prevent frailty in breast cancer survivors. Fisetin may help remove old cells that stop dividing but don't die, which can otherwise cause harm. Participants will either take fisetin or a placebo and follow an exercise plan to determine which approach is most effective. Women who have completed treatment for early-stage breast cancer and feel less energetic might be suitable for this trial. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, providing participants an opportunity to contribute to important findings.
Will I have to stop taking my current medications?
The trial requires you to stop taking certain medications, especially those with senolytic properties like curcumin or St. John's wort, 2 days before and during the study. Some medications may need to be temporarily adjusted, and others are prohibited, so it's best to discuss your current medications with the study team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that fisetin, a natural substance found in strawberries and other foods, is generally safe for people. Studies indicate that fisetin offers health benefits by reducing inflammation and acting as an antioxidant. Although researchers are still studying fisetin's effects on cancer patients, it has shown potential in reducing inflammation without significant side effects.
Exercise, the other part of the trial, is well-known for its safety and benefits, especially for breast cancer survivors. Regular physical activity can lower the risk of cancer recurrence and improve quality of life. It also enhances overall well-being and fitness.
This trial explores whether combining fisetin and exercise can help prevent frailty in breast cancer survivors. Current research suggests that these treatments are safe, with minimal risks for participants.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for breast cancer because they combine fisetin, a natural compound found in fruits like strawberries, with exercise to potentially enhance cancer treatment. Unlike standard treatments that primarily focus on chemotherapy or hormonal therapy, this approach leverages the anti-inflammatory and antioxidant properties of fisetin, which may help inhibit cancer growth. Additionally, the inclusion of tailored exercise programs could improve overall patient health, reduce treatment side effects, and boost the immune system, offering a holistic approach to cancer care. This combination aims to provide a dual benefit by directly targeting cancer cells and strengthening the body's natural defenses.
What evidence suggests that this trial's treatments could be effective for preventing frailty in breast cancer survivors?
Research shows that fisetin, a natural substance in strawberries, may help fight cancer cells. It reduces harmful cell activity and inflammation. Studies have also found that it might slow cancer cell growth and help destroy them. In this trial, some participants will receive fisetin with a physical activity handout, while others will receive fisetin combined with tailored exercise training.
Exercise greatly benefits cancer survivors by improving their quality of life, physical abilities, and energy levels. Regular physical activity is linked to lower chances of cancer returning and reduced death rates in breast cancer patients. In this trial, some participants will receive tailored exercise training with either fisetin or a placebo, while others will receive a physical activity handout with either fisetin or a placebo. Combining fisetin with exercise might enhance these benefits and help reduce frailty in survivors.36789Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for postmenopausal women who have had early-stage breast cancer treated with chemotherapy within the last year. They should be in a pre-frail state but without active cancer or serious chronic illnesses. Participants must be able to swallow pills, not on certain medications, and not involved in other similar studies.Inclusion Criteria

Treatment
Participants receive fisetin or placebo orally on days 1-3 of each cycle, with treatment repeating every 14 days for 8 cycles. Exercise training or physical activity handouts are provided depending on the arm.
Follow-up
Participants are monitored for safety and effectiveness after treatment completion, with follow-up visits on days 120 and 180, and then annually for up to 3 years.

Trial Overview
The PROFFi trial is testing if fisetin (a natural substance) combined with exercise can prevent frailty in breast cancer survivors by eliminating aged cells that may damage healthy ones. The study includes physical tests, biospecimen collection, educational sessions, and quality-of-life assessments.

Experimental Treatment
Active Control
Patients receive fisetin PO on days 1-3 of each cycle. Treatment repeats every 14 days for 8 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive individually tailored supervised exercise training consisting of 30-45 minutes of aerobic training and 20-30 minutes of resistance training three times a week over 16 weeks. Patients undergo collection of blood samples on study.
