Fisetin for Breast Cancer Survivors
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether fisetin, a natural substance in strawberries, can improve physical function in women recovering from chemotherapy for stage I-III breast cancer. Chemotherapy can cause cells to age and stop dividing, leading to inflammation and harm to other healthy cells. Fisetin might help remove these aged cells, possibly enhancing physical ability. Women who are postmenopausal, have undergone chemotherapy for early-stage breast cancer in the past year, and experience frailty (such as difficulty walking) might be suitable for this trial. Participants will receive either fisetin or a placebo to compare outcomes. As a Phase 2 trial, this research focuses on measuring fisetin's effectiveness in an initial, smaller group, offering participants a chance to contribute to important findings.
Do I need to stop my current medications to join the trial?
The trial protocol does not specify if you must stop all current medications. However, you cannot take certain medications with senolytic properties like curcumin or St. John's wort during the trial. Some medications may need to be withheld temporarily during dosing intervals. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that fisetin is likely to be safe for humans?
Research has shown that fisetin, a natural substance found in strawberries and other foods, is generally safe for humans. Studies have found that fisetin offers several benefits, such as reducing inflammation and acting as an antioxidant. It may also help fight cancer.
In cancer-focused trials, researchers have used fisetin without major safety issues. Available studies report no serious side effects linked to fisetin, suggesting it is safe for humans, especially since it comes from natural sources.
Researchers are currently studying fisetin in a trial to see if it can improve physical function in breast cancer survivors. Its presence in a Phase 2 trial indicates that earlier trials found it safe enough to continue studying its benefits. This phase usually focuses more on efficacy, as safety has already been assessed.
Overall, fisetin appears to be a promising and safe option for those considering alternative treatments after chemotherapy.12345Why do researchers think this study treatment might be promising for breast cancer survivors?
Unlike the standard treatments for breast cancer survivors, which often include hormone therapy, chemotherapy, and radiation, fisetin offers a unique approach. Fisetin is a natural flavonoid found in many fruits and vegetables, known for its antioxidant and anti-inflammatory properties. Researchers are excited about its potential because it might offer a gentler alternative by targeting inflammation and oxidative stress, which are linked to cancer progression, without the harsh side effects typical of conventional therapies. This treatment could provide a novel way to support breast cancer survivors in maintaining their health and preventing recurrence.
What evidence suggests that fisetin might be an effective treatment for improving physical function in breast cancer survivors?
Research has shown that fisetin, a natural substance found in strawberries, offers several health benefits. It possesses antioxidant and anti-inflammatory properties, which can help combat cancer and other diseases. Notably, fisetin can remove senescent cells—old cells that stop dividing but don't die. These cells can accumulate after chemotherapy, causing inflammation and harming healthy cells. Studies have demonstrated that fisetin can reduce the number of these harmful cells, potentially improving physical function in breast cancer survivors. In this trial, participants in Arm A will receive fisetin, while those in Arm B will receive a placebo. Early findings suggest fisetin may enhance physical well-being in individuals who have undergone chemotherapy.13467

Are You a Good Fit for This Trial?
This trial is for postmenopausal women aged 65 or older who have had stage I-III breast cancer treated with chemotherapy within the last year. Participants must be able to walk on their own, even if they use a cane or walker, but have a reduced walking ability (less than 400m in 6 minutes). They should not have had surgery or radiation in the past month and must agree to stop certain natural medications before and during the study.Inclusion Criteria
